Problems solved by technology

[0002] With the progress of society and the improvement of the automation level of appliances, the types of electrical appliances and electric tools are becoming more and more complete, which puts forward new requirements in terms of electricity safety. The previous leakage protectors were integrated with air switches and installed on the circuit. In the middle end, if the electrical equipment is far away from the switch, the reliability will be reduced, and it will not be automatically reset after the fault is removed after the action, which is very inconvenient to use

Abstract

The invention discloses an automatic reset device for leakage protection, comprising: an eight-pin 555 time base circuit, a relay (J), diodes (D1, D2), diode rectifier bridge stacks (D3-D6), capacitors (C, C1, C2, C3, C4, C5, C6), Zener tube (DW), resistors (R, R1), a triode (Q), a light-emitting diode, an inductor (L), of which: 555 time base circuit ground pin ( 1) Connect the capacitor (C1), the trigger pin (2) to the collector of the triode (Q), the output pin (3) to the anode of the light-emitting diode, and the reset pin (4) to connect between the resistors (R, R1) to control the voltage Pin (5) is connected to capacitor (C4), threshold voltage pin (6) is connected between resistor (R1) and capacitor (C5), discharge pin (7) is connected between resistor (R1) and capacitor (C5) , the power pin (8) is connected between the resistors (R, R1). The invention can greatly shorten the action time and improve the reliability and safety of electricity consumption.

Description

technical field [0001] The invention relates to a safety protection device for a power consumption system, in particular to an automatic reset device for leakage protection Background technique [0002] With the progress of society and the improvement of the automation level of appliances, the types of electrical appliances and electric tools are becoming more and more complete, which puts forward new requirements in terms of electricity safety. The previous leakage protectors were integrated with air switches and installed on the circuit. In the middle end, if the electrical equipment is far away from the switch, the reliability will be reduced, and it will not be automatically reset after the fault is removed after the action, which is very inconvenient to use. In order to improve the reliability of power consumption and improve work efficiency, we need a new leakage protection automatic reset device, which will automatically cut off the power supply when there is an elect...
