Description
What the utility model Anti-electricity-stealing device related to is that the user can be cut off the power supply when stealing automatically, warning device.
Usually stealing electricity phenomenon mainly contains three kinds: the firstth, and the ammeter external connection, ammeter does not change; The secondth, ammeter turnover line also connects, and the ammeter rotating speed is slack-off; The 3rd is that ammeter passes in and out line to transfer, makes the ammeter counter-rotating.Preceding two kinds of methods easily realize, the third method is difficult, because of the kilowatt-hour meter link cover of FIG by lead sealing, easily discovery.Because stealing electricity phenomenon brings numerous difficulties for the management cause of electricity, causes a large amount of energy losses, waste, simultaneously electricity filching person has also been brought the disaster that is difficult to expect, though relevant department has also taked corresponding anti-electricity-theft device, effect is undesirable.
The purpose of this utility model provides a kind of Anti-electricity-stealing device, aims at the user and can cut off the power supply automatically at off-balancesheet wiring and ammeter turnover line and when connecing, and sound and light alarm reduces stealing to reach, alleviates energy shortage situation, saves energy, safety utilization of electric power purpose.
Anti-electricity-stealing device takes following scheme to realize: Anti-electricity-stealing device has the Anti-electricity-stealing device shell, electric power incoming line, outlet are housed on the shell, and the mutual inductor connecting line is equipped with alarm, indicator light on the housing face-plate, the Anti-electricity-stealing device electric circuit board is housed in the shell, electronic devices and components are housed.Electric wiring is by forming with power detection circuit, stealing cut-offing alarming circuit.With power detection circuit by mutual inductor L1, L2, transformer B, bridge rectifier D1, D2, D3, capacitor C 1, C2, C3, C4, regulator block IC1, IC2, variable resistor W1, W2, resistance R 1, R2, R3, R4, amplifier ic chip 3 is formed.The on/off warning circuit is made up of resistance R 5, capacitor C 5, LED, triode BG, diode D4, relay J, buzzer Y.With regulator block IC1 in the power detection circuit, IC2 can adopt 7805 integrated packages, and amplifier ic chip 3 can adopt UA741 amplifier integrated package.
Anti-electricity-stealing device two coil L1, L2 electric current when normal electricity consumption equate, relay J is not worked, when stealing occurring, promptly the user passes in and out line with kilowatt-hour meter and connects, and makes the ammeter rotating speed slack-off, or the off-balancesheet wiring is not when changeing ammeter, the electric current of coil L1 is greater than the electric current of coil L2, and discharge circuit IC3 disequilibrium, relay J get electroacoustic light and report to the police, caveat people family stealing does not become, and cuts off user's power supply.This Anti-electricity-stealing device can reduce stealing electricity phenomenon, alleviates the energy shortage situation, saves energy, and safety utilization of electric power, easy for installation, cost is low, and stealing power cuts off the power supply when 10W is above automatically, and is sensitive reliable, easy to utilize.
