Abstract
The present invention is a kind of device of anti-electricity-theft usefulness, be contained in the watt-hour meter lead sealing cover, by the cross-over connection signal circuit, unhook signal circuit, control circuit and display circuit constitute, run into the stealing of cross-over connection live wire or throw off the stealing of verification hook and can cut off the electricity supply immediately, and light pilot lamp, device is in off position during normal power supply, does not have energy consumption.
Description
The present invention relates to a kind of electromechanical assembly that is used to measure the electric power time integral, in particular for the device of indication duplicity use.
Though existing anti-electricity-theft device is existing multiple; but weak point is arranged respectively; as CN89208254.2 three-phase anti-tamper device and the multi-functional power protector of CN90202871.5 under the normal power supply situation; energy consumption is all arranged; and all can only prevent cross-over connection live wire stealing before show, it is powerless to collude (making ammeter stop walking) stealing for the verification of throwing off ammeter.
The objective of the invention is to disclose and a kind ofly when normal power supply, do not consume energy, and can prevent the stealing of cross-over connection live wire, can the anticreep verification collude the device of stealing again.
A kind of arrangement on watt-hour meter for avoiding fraudulent use has inlet side live wire and the thief-proof circuit of being with screen layer, it is characterized in that anti-electricity-theft route cross-over connection signal circuit, takes off and colludes signal circuit and control circuit formation.
The cross-over connection signal circuit is that a termination is advanced the live wire screen layer, the lead of other end connection control circuit; Take off and collude signal circuit and constitute by mutual inductor, diode rectifier and controllable silicon, elementary and the school face of mutual inductor colludes in parallel, secondaryly connects a diode rectifier, and the rectifier output plus terminal connects the controllable silicon trigger electrode, negative terminal connects the controllable silicon negative pole, and the controllable silicon positive pole is connected on the live wire; Control circuit is in series by latching relay and diode, and the normally closed contact of relay is connected on respectively on live wire and the ground wire.
The present invention is installed in the watt-hour meter, and when live wire was pierced the foreskin cross-over connection, the cross-over connection signal circuit was connected live wire and control circuit, and control circuit is activated, and supply lines is cut off; Collude when being thrown off when verification, take off and collude signal circuit, live wire and control circuit are connected, the start-up control circuit cuts off supply lines, owing to passive cut-off part in ammeter lead sealing cover, not opening lead sealing can't restore electricity; This device is in off position during normal power supply, does not have energy consumption.
To further describe in conjunction with the accompanying drawings by embodiment below.
Description of drawings:
Fig. 1 is a block scheme of the present invention;
Fig. 2 is the circuit diagram of embodiment 1;
Fig. 3 is the circuit diagram of embodiment 2.
1 is the cross-over connection signal circuit among Fig. 1, the 2nd, and take off and collude signal circuit, the 3rd, control circuit, the 4th, live wire inlet wire.
Embodiment 1 is an arrangement on watt-hour meter for avoiding fraudulent use that is contained in the DD28 type single-phase watt-hour meter, entire circuit and element all are contained in the watt-hour meter lead sealing cover, the screen layer of one termination live wire 4 of cross-over connection signal circuit 1, another termination latching relay 13, taking off mutual inductor 5 primary coils that collude signal circuit 2 colludes in parallel with verification, a termination live wire just, the voltage circle 7 of one termination ammeter, the secondary coil of mutual inductor connects one by diode 8, electric capacity 9, the rectifier that resistance 10 constitutes, the trigger electrode of the positive termination controllable silicon 11 of rectifier, negative terminal connects the controllable silicon negative pole, the controllable silicon positive pole is connected on the live wire on the ammeter electric current circle left side, the latching relay 13 1 termination controllable silicon negative poles of control circuit 3, the other end is by diode 14 connecting to neutral lines 20, two normally closed contacts of latching relay are connected on respectively on live wire and the zero line, and the contact on the live wire should be connected on the left side of controllable silicon contact; For electricity filching behavior easily is found, install a display circuit additional, display circuit is in series by resistance 19 and light emitting diode 18, the one termination zero line other end of circuit is by the normally opened contact of the latching relay line of starting to exchange fire, disturb in order to eliminate extraneous signal, between live wire 4 and zero line 20 and the two ends of mutual inductor all be connected to capacitor 21 and 19.Present embodiment runs into the cross-over connection stealing or takes off verification and collude stealing and can cut off the electricity supply immediately and light pilot lamp, even electricity filching person is stood the hardship of power failure willingly, to the report of power supply fire, luminous pilot lamp can not make him escape the only eyes of the person of tabling look-up yet.
