Fuse (F2) is connected above-mentioned first output (30).
With reference to above-mentioned Fig. 7 and Fig. 8, describe the work to power supply commonly used and the automatic conversion of emergency power supply of the embodiment of the invention in detail.
By not shown resident family of unit meter and circuit breaker, when using power supply always from using power input terminal (12) input always, the power supply commonly used of this input is applied to converter section (26).At this moment, when power supply commonly used is too high, utmost point fuse (POLE-FUSE) (F1) will cut off the supply of using power supply always.In addition, power supply commonly used, by resistance (R1, R2) and be applied to behind capacitor (C1) regulation voltage by the bridge diode (rectification part (42) that D1~D4) and capacitor (C2) constitute.Power supply commonly used is carried out full-wave rectification to rectification part (42) and filter is flat, output dc voltage.Zener diode (ZD1) control overvoltage makes from the certain commutating voltage of above-mentioned rectification part (42) output.Direct voltage by above-mentioned rectification part (42) output, be applied to the induction coil (L1) of first relay (RY1), the switch of first relay (RY1) (SW1~SW2) alternation when above-mentioned induction coil (L1) has electric current to flow through, common terminal (c) is connected to contact (a), supply with power supply commonly used to first and second output (30,32).In addition, (R6, R7), (R6, R7) dividing potential drop adds to the base stage of transistor (Q1) outward, transistor (Q1) connection by above-mentioned bias resistance to be applied to bias resistance by the voltage of rectification part (42) output by resistance (R4) and diode (D5).At this moment, Zener diode (ZD2) is controlled the overvoltage of the voltage that adds by above-mentioned resistance (R4) and diode (D5).Above-mentioned transistor (Q1) one is connected, then the induction coil (L2) of second relay (RY2) has electric current to pass through, the switch (SW3) of second relay (RY2) carries out work, common terminal (c) is connected to contact (b), makes the emergency power supply that supplies to emergency power supply input (10) not be applied to commonly used/emergency light (36) or emergency load (38) thereby cut off emergency power supply.Like this, do not having under the normal condition that has a power failure, converter section (26) makes the power supply of introducing by power input terminal (12) commonly used commonly used supply to commonly used/emergency light (36).If supply with power supply commonly used to commonly used/emergency light (36), then the user can console switch (40), lights or extinguishes commonly used/emergency light (36), is used as primary light and uses.In addition, when the supply that power supply commonly used is arranged, for example make first light-emitting diode (LED1) light up as green, allow the user can confirm power supply condition of supplying commonly used by resistance (R3).
But,, supply with emergency power supply by emergency power supply input (10) because of having a power failure or the cut-out of power transmission sequence can't supply with power supply commonly used the time.If the not supply of power supply commonly used at this moment, rectification part (42) does not just have voltage output, and the induction coil (L1) of first relay (RY1) does not have electric current to pass through.If do not have passing through of electric current at induction coil (L1), the switch of first relay (RY1) (SW1~SW2) alternation then, common terminal (c) is connected to contact (b), cut off power supply commonly used to first and second output (30,32) supply, and the conversion emergency power supply, make the emergency power supply that is input to emergency power supply input (10) to first and second output (30,32).In addition, because of rectification part (42) has voltage output, so the bias-voltage that adds to the base stage of transistor (Q1) not, transistor (Q1) disconnects.Above-mentioned transistor (Q1) one disconnects, then the induction coil (L2) at second relay (RY2) does not have electric current, thereby the switch (SW3) of second relay (RY2) carries out work, common terminal (c) is connected to contact (a), changes emergency power supply to the three outputs (34) that make to emergency power supply input terminal (10) supply.Like this, during power failure, converter section (26) conversion emergency power supply makes that lighting input by the emergency power supply of emergency power supply input terminal (10) introducing uses always/emergency light (36), supplies to emergency load (38) simultaneously.At this moment, in case supply with emergency power supply to commonly used/emergency light (36), then irrelevant with the operation of switch (40), light commonly used/emergency light (36) and be used as the primary light use.In addition, when the supply of emergency power supply, such as making second light-emitting diode (LED2) be lit up as redness, allow the user can confirm the state of emergency power supply by resistance (R8).
Moreover, will be by the power supply of power input terminal (12) introducing commonly used, by converter section (26), when supplying with, be cut off if use power supply always because of having a power failure by first and second output (30,32), then the charging of delay circuit (44) is at capacitor (C3, C4, power supply discharge certain hour C5).(till power supply discharge C5), transistor (Q1) continues to keep conducting state for C3, C4, and the induction coil (L1) of second relay (RY2) has electric current to pass through, and the 3rd switch (SW3) makes common terminal (c) be connected to contact (a) at capacitor in above-mentioned charging.Afterwards, after the discharge of certain hour finished, transistor (Q1) disconnected, and the induction coil (L1) of second relay (RY2) does not have electric current to flow through.If on the induction coil (L1) of above-mentioned second relay (RY2), do not have flowing through of electric current, then second relay (RY2) makes the 3rd switch (SW3) connect common terminal (c) and contact (b), the conversion emergency power supply makes the power supply of introducing by emergency power supply input (10) supply to commonly used/emergency light (40) and emergency load (38).Therefore,, supply with emergency power supply, prevent that the short circuit of power supply commonly used and emergency power supply from taking place because of after the power supply commonly used that has a power failure is cut off a period of time.
In contrast, will be by the emergency power supply of emergency power supply input terminal (10) introducing, by converter section (26), when supplying with by first~the 3rd output (30,32,34), if power supply commonly used is supplied to once more, then by the voltage of rectification part (42) output capacitor (C3, C4, C5) charging certain hour to delay circuit (44).(till C5) charging finished, transistor (Q1) continued to keep off-state for C3, C4, and the induction coil (L1) of second relay (RY2) does not flow through because of there being electric current, and the 3rd switch (SW3) makes common terminal (c) be connected to contact (b) to above-mentioned capacitor.Afterwards, after the discharge of certain hour finishes, transistor (Q1) conducting, the induction coil (L1) of second relay (RY2) has electric current to flow through.In case the induction coil (L2) of above-mentioned second relay (RY2) has electric current to flow through, then the 3rd switch (SW3) of second relay (RY2) work, make common terminal (c) be connected to contact (a), make power supply commonly used supply to commonly used/emergency light (40) by power input (12) commonly used.Therefore, because of power failure is supplied with when the supply of power supply commonly used being arranged once more after the emergency power supply, through supplying with power supply commonly used after the certain hour, thereby prevent power supply commonly used and emergency power supply is short-circuited, prevent that simultaneously power supply adverse current commonly used is to emergency power supply input terminal (10).
The function of unaccounted here fuse (F2) is, is connected first output (30), if detect overvoltage when the supply of emergency power supply or power supply commonly used, then cuts off the electricity supply automatically, prevents the fire that causes because of electric leakage etc.
As mentioned above, according to the present invention, can be stably to building supply powers such as apartment house and office buildings; Can reduce the raw material original cost; Supply with at the power supply of load-side wired circuit, adopt commonly used/emergency button (SWITTCHING) dual-purpose three-circuit mode to replace four circuit of existing each two circuit commonly used, emergent two circuit with emergent common two circuit commonly used, reduce the prices of raw and semifnished materials thereby can reduce to connect up.Use apparatus of the present invention, when resident family of unit and circuit one side and load one side generation electrification, can in time cut off power supply commonly used and emergency power supply, prevent that the electrical equipment accident that invades other resident families from taking place, and keep with operating switch easily.
Under existing unidirectional situation, MCCB (MOLDED CASE CIRCUIT BRAKER) and ELCB (EARTH LEAKAGE CIRCUIT BERAKER, ELCB), can not use input of TW two wire power supply and TW two wire power supply to export and realize the commonly used of power supply and four inputs of meeting an urgent need.But the present invention can enough two inputs commonly used, emergent two import automatic control power supplies and realize the three-wire type input, enough first and second outputs (30 of civil time energy, 32) output, and energy enough first reaches~the three output (30 when the supply of emergency power supply, 32,34) supply with emergency power supply, can supply with emergency power supply to emergency load (38) and commonly used/emergency light (36) during power failure.At this moment switch (40) conducting between second output (34) and the commonly used/emergency light (36), so even emergency power supply is input into from commonly used/emergency light (36) or emergency load (38), first to the 3rd switch (SW1~SW3) conducting because of converter section (26), so can't adverse current extremely use mains side always, prevent that the power supply adverse current is to other resident families.
In addition; resident family of the described power supply automatic converting device of the present invention unit of being arranged on distribution board the time; even when emergent particularly in fire incident or when the power supply accident, line short etc. of load-side takes place in the resident family when having a power failure; also can protect the circuit of each resident family; thereby power supply supplies to the emergency load, can stably provide power supply by resident family.
In addition, when in the resident family of building ground unit of apartment house and office building etc., device of the present invention being set, provide stable power, and primary light is used as dual-purpose electric light emergent, commonly used replaces use, can save cost economically by emergency power supply commonly used; Can supply with the emergency load to the three-wire type out-put supply that supplies to emergency light commonly used.
As mentioned above, the present invention possesses the commonly used/emergency power supply converter section of automatic conversion power supply commonly used and emergency power supply at resident family of unit distribution board, make that supply is used power supply always, supplies with emergency power supply when emergent under normal condition, and emergency light is also used as often lamp, emergency light, therefore need not possess emergency light in addition, reduce expense.
Moreover, need not the vertical stringing of mode side by side be set in order when having a power failure, to light emergency light between resident family, prevented the interlayer noise, eliminated that private life is encroached on and many lives of causing because of noise inconvenient.
In addition, the situation of family expenses automatic equipment has following several advantage: the emergency power supply is provided, need not prepares reserve battery, the container body of outer cover that has dwindled the family expenses automatic equipment that is used to pack into is long-pending, has reduced the root that crackle takes place; The charging device and the reserve battery that do not need reserve battery are so reduced expense.
In addition, also has following advantage: can provide emergency power supply in Automatic Fire Extinguisher during breaking out of fire during power failure, can suppress fire in early days, take precautions against the generation of the greatest damage that brings by fire, and when having a power failure, supply with emergency power supply in gas alarm valve, the fire incident that advance preventing causes because of coal gas leaks outside.
