Description of the Invention: [Technical Field of the Invention] The present invention relates to a hybrid relay including a mechanical contact switch and a semiconductor switch. [Prior Art] Conventionally, in order to switch between power supply and disconnection of a load (load) of an inverter circuit that has an inverter control such as a lighting fixture, a parallel connection is always used. Hybrid relay for mechanical contact switches and semiconductor switches. A load having an inverter circuit is provided with a large-capacity smoothing capacitor in order to convert an alternating voltage into a direct voltage. When an AC power supply (alternadngp〇wer supply) is connected to the load, a large current flows into the smoothing capacitor, so that an impulse current flows into the load. In particular, in the case of a high load with a high power supply voltage, since the flushing key flowing into the load is large, the connection between the load and the alternating current power source == there is a large current based on the inrush current. Therefore, in the hybrid relay, in order to avoid the large current flowing to the mechanical contact based on the inrush current, the mechanical contact contact pair (pair-like pair) is transferred, firstly, In the following description, the "opening state of the semiconductor" and "closing the mechanical contact switch" are respectively ★ ° ^ to make the semi-conductive 4 201222609 39558pif body open, 〇N", "make mechanical" Contact switch 0N". In the following description, "the semiconductor switch is turned off and the non-conducting contact switch is turned off" is referred to as "conducting the semiconductor" and "turning the mechanical contact _OFF". After flowing the semiconductor switch to the load, the electric power is supplied to the load, so that the τ mechanical contact switch flows into the large electric power, and the two-point welding is connected before the touch and a hybrid relay is provided to constitute the point switch and the semiconductor switch before the device The same type of mechanical contact switch is added to the half === switch (for example, refer to Patent Document 1). Refer to the schematic _ of the two pairs of circuits. The hybrid relay 1 of the metering age relay is connected to the alternating current supply 2 and to the alternating current source 2 and negative ', Λ, and negative =:=. The mixing_includes: the terminal is connected to the AC power supply 2 of the end of the load 3, and the other end is connected to the load 3. The other end of the mechanical contact switch ^ 201222609 39558pif includes both ends connected to the terminal 10, The contact portion S1 of the u; the second machine contact switch 13' includes a charm S2, the 1 is connected to the connection node of the end of the switch 1 and the contact portion si; the semiconductor switch M includes the three-terminal bidirectional switch (4) The T1 electrode is connected to the other end of the contact portion and the T2 electrode is connected to the terminal u; and the signal processing circuit 16 performs the ON of each of the first and second mechanical contact switches 12, 13 and the semiconductor switch ( Close) / 〇 FF (disconnect) control. The supply of electric power from the AC power source 2 to the load 3 via the hybrid relay 1 is performed in accordance with an instruction from the signal processing circuit 16. Specifically, the second mechanical contact switch 13 and the semiconductor switch 14 are respectively (10) in accordance with an instruction from the signal processing circuit 16. Further, after the electric power is supplied from the AC power supply 2 to the load 3, the first mechanical connection is connected in parallel to the second mechanical contact switch 13 and the semiconductor switch 14 connected in series, in response to an instruction from the signal processing circuit 16. The dot switch 12 is 〇1^, and then the semiconductor switch 14 and the second mechanical contact switch 13 are sequentially turned FF in accordance with an instruction from the 彳§ number processing circuit 16. As described above, the start of the supply of electric power from the AC power source 2 to the load 3 is a timing at which the three-terminal bidirectional controllable switch S3 of the semiconductor switch 14 is turned ON, via the second mechanical contact switch 13 and the semiconductor. The switch circuit 4 is formed by a feeder circuit. Further, the power supply from the AC power source 2 to the load 3 is performed after the second mechanical contact switch 13 and the semiconductor switch 14 are both FF, and then passed through the feed circuit including the first mechanical contact switch 12. Next, in the state where the first mechanical contact switch 12 is ON, the supply of electric power from the AC power supply 2 to the load 3 via the hybrid relay 1 is turned off according to an instruction from the signal processing circuit i6. Specifically, the second mechanical contact switch 13 and the +conductor switch U are turned ON according to an instruction from the signal processing circuit 16. Thereby, the feed circuit that passes through the second mechanical contact switch 13 and the semiconductor switch 14 is established and flows to the load 3 for electric pickup. [5 knives flow to the second mechanical type (4) head 13 and the semiconductor switch Μ to reduce the current flowing to the ith mechanical contact switch 丨2. Immediately after the instruction from the signal processing circuit 16, the "the mechanical contact switch 12" is turned OFF, and the semiconductor switch 14 and the second mechanical contact switch 13 are sequentially turned OFF. Further, the disconnection of the power supply from the AC power source 2 to the load 3 is performed in synchronization with the OFF of the semiconductor switch 。. The hybrid relay i disclosed in Patent Document 1 is one in which the i-th mechanical contact _ 12 provided on the load-oriented feed circuit is set to a flash-lock type, and only the ith mechanical contact is opened and closed. The switch η 7' ^ causes the second mechanical contact switch 13 and the semiconductor switch 14 to move, thereby reducing the power consumption when the hybrid relay 1 is used.

EXAMPLES [Embodiment] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings which form a part of this specification. In the entire drawings, the same reference numerals will be given to the same or like parts, and the description will be omitted. <First Embodiment> A hybrid relay according to a first embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic circuit diagram showing a circuit 2 of the hybrid relay 1 of the first embodiment. 1. Configuration of Hybrid Relay 1 As shown in Fig. 1, the hybrid relay of the first embodiment is closed to the AC power supply 2 and the load 3 by the AC power supply 2 and the load 3 connected in series. That is, the power supply from the AC power source 2 to the load 3 is 201222609. The 39558pif force supply is disconnected by the hybrid relay 1 being in an ON state and an OFF state. The AC power source 2 is, for example, a commercial power of 100 V:; 3 is set to include, for example, a illuminator of fluorescent light = - including: terminal 1G, which is connected to the other end of the load 3 #都^父抓电源2; terminal 1 is directly connected to the end; · 1st The mechanical contact switch 12 has a contact portion S1 that is connected to the end, and the second mechanical contact point S2 has one end connected to the end *1〇 and the connection node 2, the connection node; I#门关甘—S3, j: T1歼, eight w two-terminal bidirectional controllable switch, the u electrode is connected to the other end of the contact part S2 and =__路16' The circuit configuration in which the first and second mechanical or the semiconductor switches 14 are respectively in the state of (10) and the hybrid relay 1 is performed will be described in detail. Mixed! In the middle of the contact switch of the second mechanical contact switch 13! The series circuit of the three-terminal bidirectional controllable pin of the 4th is 疋1. The mechanical contact switch 12 is connected in parallel at the terminals 1〇 and 丨丨. The first mode is irrelevant 丨 2 is the _ handle mechanical contact opening, 'and includes an electromagnetic coil L1 that generates an electromagnetic force for switching the contact portion S1 to the (10) state, and is generated for the contact point The portion S1 is switched to the electromagnetic coil L2 of the electromagnetic force in the 0FF state. That is: the electromagnetic coils L1, U constitute the first! The first § zone of the mechanical contact switch 12. The second mechanical contact switch 13 is of the rated excitation type (the seventh is connected to the field 201222609 39558pif, and the title includes the electromagnetic coil B which generates the electromagnetic force for the contact portion S2 to be in the 々 state. That is, the electromagnetic wire surround constitutes the second driving portion of the second mechanical contact switch 13. In the mechanical contact switch 12, the electromagnetic coil is connected to the diode (the cathode electrode of the ", the above-mentioned diode L = one end of the pole electrode connected to the money processing circuit 16 m 1 is connected to the cathode electrode of the diode D4 ^ is connected to the signal processing circuit 16. The other electromagnetic wires are connected to each other. In addition, the electromagnetic coils u, L2 The remote ϋ rm is connected to the anode electrodes of the diodes m and D2; ΐ ;;: “grounding” means connected to the hybrid relay 1: and the cathode electrodes of the 'diodes m and 02 are connected to 3 strings = ^ from the cathode electrode. Therefore, the 'first mechanical contact switch 12 = connected: the electromagnetic coils L1, L2, the anode of the anode electrode, and the potential plate D5. An anode electrode of the electromagnetic coil L3 Connected to the ground, the connection point κ 14 formed by the electromagnetic cathode electrode is made up of three ends The 201222609 39558pif capacitor CM, the resistor R1 and the capacitor C2 connected to the controllable (four) phantom, parallel connection between the T2 electrode and the inter-polar email of the two-way two-way controllable switch S3 are connected to the three-terminal bidirectional controllable 矽The resistor R2 of the T1 electrode of the switch S3 and the photo triac coupler 15 including the optical bidirectional thyristor S4 (the T1 electrode is connected to the other end of the resistor R2) are also formed. When the contact portion S2 of the mechanical contact switch 13 is ON, a large current based on the inrush current also flows to the semiconductor switch 14, so the resistor R2 is preferably a surge resistance. In addition, the capacitor C2 is opposed to the optical bidirectional thyristor S4. And a series circuit of the resistor R1 is connected in parallel and connected in series with the resistor R2. The resistor R2 is connected in series with the capacitor C2 to form a buffer circuit in the semiconductor switch 14. As shown in Fig. 1, the buffer circuit is opposite to The first mechanical contact switch 12 is disposed in parallel connection. The optical two-way thyristor 15 further includes a light emitting diode LD (Laser Diode), and the anode electrode of the light emitting diode LD is connected via a resistor R3 is connected to the signal processing circuit 16 and the cathode electrode is grounded. Further, in the optical two-way thyristor 15, the optical signal from the light-emitting diode LD is incident on the optical bidirectional thyristor S4, and the T2 electrode is connected to the three-terminal bidirectional The gate electrode G of the switch S3 can be controlled. In addition, the light bidirectional thyristor S4 is a semiconductor switching element having a zero cross point of arc function, and when an optical signal from the light emitting diode LD is incident The conduction is started after the center voltage (reference voltage) of the AC voltage of the AC power source 2 is detected on the T2 electrode side of the optical bidirectional thyristor S4. 2. Power Supply of Hybrid Relay 1 Referring to the timing chart of FIG. 2, the operation of the hybrid relay 1 when the power is supplied from the AC power supply 12 201222609 39558pif clear power supply unit is 1 load 3 is passed through the first embodiment. Hybrid relay ΐϊ Mixed relay crying! The gas is a timing chart of an example in which the power is supplied to the load 3 and the operation is performed at the time of the operation. Hai ^ 'rich from the turbulent power supply 2 to the load 3 supply a θ processing circuit 16 indicates that the power is indicated by the signal, the drive current is supplied, and the power n is included in the electromagnetic coil according to the signal. Generate electromagnetic suction on the force, package t! Diode D5 as a use. 6. The flow connected in parallel with the electromagnetic coil L3 prevents the diode from being used; the reverse voltage portion S2 of the current flowing through the electromagnetic coil [3] is connected to the voltage at the time / ^ 32 mechanical contact switch 如图 as shown in FIG. 2 Lower ^ Forgiveness, so the junction of the contact part of the semi-guided Hin shown in Figure 1 'in the semiconductor switch 14, Sa Jifeng ¥ body _ 14 resistance R2, and (10) wrong consists of: 1 series circuit in parallel When the electric connection body J4 and the resistance force are connected, the generation of noise can be suppressed when the time = the negative supply is ON, and the contact portion S2 can be controlled by the malfunction of the X-switch S3 (see the figure, 6) ° Three-terminal bidirectional snubber circuit, the rendezvous relay i of the first embodiment is supplied with power of the load 3 at a preferred = 201222609 39558 pif source 2 by the malfunction of the bidirectional (four) switch S3. After the contact portion S2 of the mechanical contact switch 13 is turned ON at the time u, the signal processing circuit 16 supplies the _ current to the light-emitting diode LD at time t2. Thereby, in the light-direction thyristor H 15 , the light-emitting diode LD emits light, and the light-directed thyristor fluid S4 receives the light-emitting optical signal. The optical two-way thyristor S4 has a zero-crossing point arc function. As shown in FIG. 2, when it is detected that the AC voltage from the AC power source 2 becomes the center voltage as the reference voltage (time t3), the optical two-way thyristor S4 becomes ON. status. By the ON state of the optical bidirectional thyristor S4, the AC current from the AC power source 2 flows to the parallel circuit of the resistor R1 and the electric valley state C1 via the resistor R2 and the optical bidirectional thyristor S4. The parallel circuit of the resistor ri and the capacitor ci operates to supply a current to the gate electrode G of the triac S3, and flows current to the T1 electrode-T2 electrode of the triac S3. The inter-electrode becomes the 〇N state, that is, the triac control S3 becomes the 0N state (time t3). Thereby, the load 3 is electrically connected to the AC power source 2 via the second mechanical contact switch 13 and the semiconductor switch 14' of the hybrid relay 1, so that the power of the AC power source 2 is supplied to the load 3. At this time, since the inrush current flows from the AC power source 2 to the load 3, the three-terminal bidirectionally controllable neon switch s3 and the optical bidirectional gate fluid S4 in the ON state also flow into a large current based on the inrush current. Since the optical two-way thyristor S4 has a zero-crossing point arc function, the timing of the optical two-way thyristor S4 in the 〇N state is not uneven with respect to the period of the alternating current voltage from the alternating current power source 2, so that the rush current can be suppressed. Uneven current flow. 201222609 39558pif After the two-terminal bidirectional control switch S3 changes to the 〇N state at time t3, the signal processing circuit 16 supplies the current that becomes the drive current to the electromagnetic coil u via the diode D3 at time t4. At this time, the first mechanical contact switch 12, the diode D1 functions as a countercurrent prevention diode for preventing current flow to the electromagnetic coil Li, and the diode 〇4 prevents current from flowing to the electromagnetic coil L2. As a result, the j-pulse current flows to the electromagnetic coil L1, and the electromagnetic attraction force temporarily acts. 帛1 The contact portion S1 of the mechanical contact switch 12 is in the 〇N state (time t5). And because of the first! Since the mechanical contact switch 12 is of the question lock type, the contact portion S1 is kept in the ON state even if no current is supplied to the electromagnetic coil L1. Further, the contact portion S1 of the first mechanical contact switch 12 is turned ON at time t5. The current from the AC power source 2 flows to the contact portion S1, and the current does not flow to the three-terminal bidirectional controllable port. Switch magic. Therefore, in synchronization with the state of 〇N of the contact portion S1 of the first mechanical contact switch 12, at time t5, the electrode of the third electrode of the three-way bidirectionally controllable switch S3 is turned OFF to make the three ends Two-way controllable stone eve _ % becomes 〇 ff sad. Further, even after the time t5, the contact portion S1 of the i-th mechanical contact switch 12 is in the ON state, so that the electric power from the AC power source 2 to the load 3 is continuously supplied. When the two-terminal bidirectional controllable switch S3 is turned OFF at time t5, the ^th processing circuit 16 stops supplying the drive current to the electromagnetic coil L3 of the second mechanical contact switch 13 at time 16. #, Since the supply of current to the electromagnetic coil L3 is stopped, the electromagnetic attraction force of the rated excitation exciter 2 mechanical contact switch 15 201222609 39558pif disappears, and the contact portion S2 of the second mechanical connection 13 becomes 〇 FF status. Further, at time t5, the L (6)' signal processing circuit 16 stops supplying the drive current to the light-emitting diode LD. when? When the two-terminal bidirectional controllable switch s3 becomes 0, the dog switch 13 is in the OTF state, so that the contact current is distributed in the feed circuit formed by the second mechanical switch and the semiconductor switch 14, the contact Qiu Jun 9 recognizes that the contact point of the machine is OTF. Therefore, in the state where the second ϋ 3 is _, the contact portion S2 can be prevented from being generated, so that the power supply of the second mechanical type switch-off 13 can be prevented from being disconnected six times, and the reference is made. The timing chart of FIG. 3 is a description of the operation when the power supply is turned off by the power supply of the hybrid relay 1 from the y_ to the load 3 or the like. Fig. 3 is a view showing a state in which the hybrid relay according to the first embodiment is mounted. In the case of FF, the timing chart of the example of the operation sequence of the flap relay 1 when the power supply to the carrier 3 is turned off is exemplified. To the negative ί:,: Before the t7, the state of the AC power supply 2 (10) includes the three-terminal contact switch 13 and the point S2 is OFF. The semiconductor switch 14 to the controllable switch S3 is connected to the power supply 2 from the parent power supply 2 to the load 3. The hybrid relay 1 (10) is indicated by the signal processing circuit 16 16 201222609 39558pif. When power is supplied to the load 3 as shown in FIG. 3, the processing circuit 16 supplies a drive current from the AC power supply L3, and outputs a current for the electromagnetic coil at the time t7, and the drive is supplied to the electromagnetic coil C according to the signal. The second mechanical magnetic attraction force of the circle L3 includes that the electromagnetic wire timing t8 becomes 0N. The contact portion S2 of the contact switch 13 is lowered as indicated by 3. The voltage between the contacts that owe the contact portion S2 is as shown in the above. In the above, the semiconductor switch 14 Θ, _ is the resistance of the main switch 14 of the 槿 仏 仏 t t t t t t + + + + The capacitor c2 provided in such a manner that the bidirectional thyristor S4 is connected in parallel with the resistor path has a snubber circuit. When the power from the AC power supply 2 to the load 3 is turned off, the snubber circuit can suppress the generation of noise when the second mechanical contact unit S2 is turned on at time t8, and the result is == The bidirectional (four) switch S3 malfunctions (see Fig. 6). In other words, with the snubber circuit, the hybrid relay i of the first embodiment can supply and disconnect the power from the AC power source 2 to the load 3 at an appropriate timing without causing malfunction of the two-terminal unidirectionally steerable switch S3. After the contact portion S2 of the second mechanical contact switch 13 is in the ON state of the time (4), the signal processing circuit 16 is copied at the time, and the pulse current serving as the drive current is supplied to the electromagnetic coil [2 via the two body D4. At the time of °, the J-mechanical contact switch 12 Yin, the diode acts as a countercurrent to the current of the long electromagnetic coil L2 to prevent the diode from being pinched ''the diode m prevents the current from flowing to the electromagnetic coil". Thereby, the punch = flow 17 201222609 39558pif = the magnetic coil L2 'the electromagnetic force temporarily acts, and the contact portion S1 of the second mechanical contact switch 2 is turned OFF (time t10). The current connected to the contact switch u flows to the second mechanical S3 axle switch 14. Further, the signal processing circuit 16, ^ J t7 supplies a drive current to the light-emitting body LD. Thereby, the T1 electrode of the thyristor S4 is applied to the thyristor fluid; and the micro S1 is applied to the junction of the contact point portion T1 of the $1 _ type contact switch 12 before the _t9. The T1 electrode-T2 electrode of the 'three-terminal bidirectional controllable Shihua switch S3 is synchronously turned into the 〇n state at time u〇.

Therefore, the flow source 2 supplies electric power to the load 3 at time (10). The sub-point 1 continues, and only the time after U0, the signal processing circuit 16 supplies the drive current of the photodiode LD. The τ stop 赉 fluid S4 is irradiated from the light-emitting diode LD, and the alternating current voltage of the optical two-way gate power source 2 becomes the center voltage, and the field from the parent fluid S4 is turned OFF. Two-way with the light: two first 〇 = 18 201222609 39558pif %, the two-terminal bidirectional controllable switch S3 becomes the 〇FF state, so that the semiconductor switch 14 as a whole becomes the 〇FF state. Thereby, the feed circuit from the AC power source 2 to the load 3 is turned off, so that the power supply from the AC power source 2 to the load 3 is stopped. Further, after the "no-number processing circuit 16 stops supplying the driving current to the light-emitting diodes", the supply of the driving current to the electromagnetic coil L3 is stopped at time t13. In other words, after the semiconductor switch 14 as a whole is in the 〇 ff state, the excitation of the electromagnetic coil L3 is stopped, and the contact of the contact portion S2 of the second mechanical contact switch 13 is brought to the 0FF state. At this time, the semiconductor switch 14 as a whole has been turned OFF, and the current does not flow to the second mechanical contact switch 13, so that the arc does not occur even when the contact of the contact portion S2 is in the 〇FF state. Thereby, the contact of the second mechanical contact switch 2 3 can be prevented from being consumed. In the hybrid relay unit of the first embodiment, a snubber circuit is connected in parallel to the first mechanical contact switch 12, and the snubber circuit pack 3 constitutes a resistor R2 of the semiconductor switch 丨4 and a bidirectional gate with the light. A series circuit of capacitors C2 provided in a manner in which fluids S4 are connected in parallel. In the hybrid relay 1 of the first embodiment, the number of components is not increased more than necessary by simply providing the capacitor C2, and even in the 〇N state corresponding to the second mechanical contact switch 13, When the contact of the mechanical contact switch 13 includes a noise component, the occurrence of malfunction of the semiconductor switch 14 and the load 3 can be effectively suppressed. <Modification 1 of First Embodiment> As shown in Fig. 1, the snubber circuit of the hybrid relay i of the first embodiment is a resistor R2 constituting the semiconductor switch 14, and a bidirectional gate 201222609 39558pif fluid S4 The series circuit of the capacitor C2 provided in parallel with the series circuit of the resistor R1 is formed. In order to reduce the number of components of the hybrid relay 1, it is preferable that the circuit configuration of the hybrid relay 1 of the first embodiment is 0. However, in the hybrid relay of the present invention, the snubber circuit is not limited to the resistor R2 and the capacitor C2. An example of formation. In the first modification of the first embodiment, another example of the formation of the snubber circuit will be described with reference to Fig. 4 . FIG. 4 is a schematic circuit diagram showing a circuit configuration of a hybrid relay 1a according to a first modification of the first embodiment. In the hybrid relay ia shown in Fig. 4, the same reference numerals are given to the same components as those of the hybrid relay 1 shown in Fig. 1. Since the operations of the respective portions denoted by the same reference numerals are the same as those of the respective portions of the hybrid relay 1 of the first embodiment, the description of the operation will be omitted. In the hybrid relay 1a of the first modification of the first embodiment, a snubber circuit is formed by a series circuit of a resistor R4 and a capacitor C4 provided in parallel with the semiconductor switch 14a. In other words, compared with the hybrid relay 1 of the first embodiment, the modification of the second embodiment: "the relay la" is the additional resistor R4 and the capacitor C4, so that the number of zeros is increased, but similarly, even When the 0N state of the second mechanical contact _ is in contact with the contact component between the contacts of the 机械2 mechanical contact switch 13, the occurrence of malfunction of the semiconductor can be effectively suppressed. 'For example, and specifically, when the power is supplied from the AC power source 2 to the load 3, the flat 20 201222609 39558pif Fig. 2 Similarly, the second mechanical contact switch can be turned on at the time U by the resistor R4 and the capacitor C4.
