Water outlet power failure intelligent electric leakage protector and control method thereof

Abstract

The invention discloses a water outlet power failure intelligent electric leakage protector and a control method thereof. The water outlet power failure intelligent electric leakage protector comprises a rectification and voltage stabilization circuit for power supply. The water outlet power failure intelligent electric leakage protector comprises a ground wire abnormality live detection module, a voltage / current mode switching module, a logic control driver, a zero sequence electric leakage detector, a zero sequence electric leakage self-detector, a power-on coil and a maintaining coil. According to the water outlet power failure intelligent electric leakage protector and the control method thereof, defects and potential safety hazards of all existing electric leakage protector are overcome, and the water outlet power failure intelligent electric leakage protector is intelligent, safe and reliable; when a water outlet power failure occurs, the water-electricity isolation using effect is achieved, and no potential using safety hazards exist; the abnormality caused by all power-on and grounding errors of a ground wire is overcome, and the system can achieve effective recognition detection and control; the self-detection function is added, and potential failure safety hazards are eradicated.

Description

technical field [0001] The invention relates to an electrical safety device, in particular to an intelligent leakage protector for water outlet and power failure and a control method thereof. Background technique [0002] The protection function of the leakage protector is based on the premise that the power supply is normal, and the ground wire is abnormally charged or the load is leaking to provide the protection function of cutting off the load power supply circuit. Because users generally use the socket switch to cut off the power supply of the leakage protector. The purpose of energy saving has been achieved by stopping the machine. Because of this, if the leakage protector loses its working power, if the ground wire is abnormally charged at this time, the leakage protector will not trip and cause an electric shock. And so on, poor contact with the socket is also equivalent to turning off the power supply of the leakage protector, which seriously affects personal safety...

[0002] The protection function of the leakage protector is based on the premise that the power supply is normal, and the ground wire is abnormally charged or the load leaks to provide the protection function of cutting off the load power supply circuit. Because users generally use the socket switch to cut off the power supply of the leakage protector. The machine stops working to achieve the purpose of energy saving. Because of this, if the leakage protector loses its working power, if the ground wire is abnormally charged at this time, the leakage protector will not trip and cause an electric shock.

And so on, the poor contact of the socket is also equivalent to turning off the power supply of the leakage protector, which seriously affects the hidden danger of personal safety.
