Description
The utility model belongs to appliance field, is specially adapted to single-phase watt-hour meter.
At present, all there is watt-hour meter in family, is used for measuring oneself power consumption, pays the electricity charge according to oneself power consumption.Since some other in order to pay the electricity charge less, change the circuit of watt-hour meter privately, make the watt-hour meter metering inaccurate, reach the purpose of paying the electricity charge less.Change the circuit of watt-hour meter, its main method is that connecting to neutral promptly reaches watt-hour meter and do not walk over the ground, does not measure, and just can not pay the electricity charge with live wire and zero line transposition.In order to change such situation at present, will be on the basis of existing watt-hour meter, design a kind of circuit phase line recognizer that live wire and zero line can not be replaced.
The purpose of this utility model will design the phase line recognizer that a kind of live wire and zero line can not replace exactly, is installed on the single-phase watt-hour meter, prevents stealing.
The utility model major technique is on former watt-hour meter circuit, connects a phase line recognizer, and the phase line recognizer is made up of two parts, recognizer and electronic switch; Recognizer is connected on going out between end line and the electronic switch of live wire, and electronic switch is connected on the inlet side line of zero line and goes out between the end line.Recognizer is going out to hold on the live wire exactly, connects a step-down current limiting capacitance, delivers to bridge rectifier through the electric current of step-down current limliting, and the direct current after rectification is delivered to another capacitor filtering, delivers to relay through the filtering after-current, and on bridge rectifier ground wire is arranged.Electronic switch is to be connected on zero line inlet side line and to go out between the end line; electronic switch triggers the contact that is connected to a relay on the loop; this contact is closed after the adhesive of recognizer repeat circuit; promptly connected the The Trigger of Bidirectional Triode Thyristor loop, triggered the loop and form, after controllable silicon triggers by resistance and diac and relay normally open contact; make zero line inlet side line and go out the end line connection; face and resistance is arranged, the capacitance-resistance absorption circuit that electric capacity is formed is as the bypass of controllable silicon overvoltage protection.
The advantage of phase line recognizer is: after single-phase watt-hour meter had been used, the user is the commutation stealing arbitrarily, and after this mainly was commutation, relay can not get due electric current, just can not adhesive, and triggering the loop can not conducting, and therefore, the user can not get power supply.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is according to the wiring diagram that the utility model proposes, and is master map; Fig. 2 is a wiring diagram of the present utility model.
Describe in detail according to detail and the working condition that the utility model proposes below in conjunction with Fig. 1, Fig. 2.
On the wiring diagram of original watt-hour meter, as shown in Figure 2, connect a phase line recognizer as shown in Figure 1, the phase line recognizer is made up of two parts, recognizer (16) and electronic switch (17), recognizer (16) is connected on live wire and goes out between end line (2) and the electronic switch (17), and electronic switch is connected on the inlet side line (3) of zero line and going out between the end line (4) of zero line.Recognizer goes out to connect step-down current limiting capacitance (12) on the end line (2) at live wire exactly, through the electric current of step-down current limliting through bridge rectifier (13) rectification, through filter capacitor (14) filtering, deliver on the relay (15) again, and a ground wire (5) is arranged on bridge rectifier.Therefore recognizer (16) is made up of step-down current limiting capacitance (12), bridge rectifier (13), filter capacitor (14), relay (15), ground wire (5).Electronic switch (17) is connected on zero line inlet side line (3) and goes out between the end line (4), the composition of electronic switch is to have the triggering loop of a two-way controllable silicon (7) and a capacitance-resistance to absorb the bypass composition, the capacitance-resistance that has resistance (6), electric capacity (8) to form absorbs bypass, the triggering loop that another has resistance (10), diac (11) and relay normally open contact (9) to form.Relay contact (9) is promptly closed after relay (15) adhesive, and the triggering loop of just having connected bidirectional triode thyristor (7) makes the inlet side line (3) of zero line and goes out end line (4) conducting, and watt-hour meter just can normally use.If the user is in order to pay the electricity charge less, zero line and live wire transposition, relay (15) just can not get power supply, relay (15) just can not adhesive, bidirectional triode thyristor triggers the loop and can not conduct electricity, inlet side line (3) with go out end line (4) just can not conducting, the user just can not electricity consumption.
Claims (3)
1, a kind of anti-electricity-theft phase line recognizer is characterized in that: phase line is known device and is made of recognizer (16) and electronic switch (17) two parts; Recognizer is connected on live wire and goes out between end line (2) and the electronic switch (17), and electronic switch is connected on the inlet side line (3) of zero line and going out between the end line (4) of zero line.
