Problems solved by technology

[0002] At present, when people use household appliances, they directly connect the household appliances to the mains power supply. When there is a leakage, the power supply is automatically disconnected, which has potential safety hazards. On the other hand, some existing leakage protection switches are not compact in structure and safe Low resistance, prone to short-circuit faults, easy to cause personal electric shock and damage to household appliances

Abstract

The invention discloses an electric leakage protector. When electric leakage of an electrical appliance occurs and reaches an electric leakage set value, a tripping device acts to cut off connection between the live line, neutral line and ground line of a power supply and loads and protect personal safety and the electrical appliance. When circuit break of any of the live line, neutral line and ground line of the power supply occurs, the electric leakage protector cuts off the power supply to prevent electric shock accidents due to connected live line. The electric leakage protector has the advantage that the live line is connected before connecting of the neutral line and the ground line and cut off after cutting off of the neutral line and the ground line.

Description

[Technical Field] [0001] The invention relates to a leakage protector. [Background technique] [0002] At present, when people use household appliances, they directly connect the household appliances to the mains power supply. When there is a leakage, the power supply is automatically disconnected, which poses safety hazards. On the other hand, some existing leakage protection switches are not tightly structured and safe. Low performance, prone to short-circuit failure, easy to cause personal electric shock and damage to household appliances. [Summary of the Invention] [0003] The present invention overcomes the shortcomings of the above-mentioned technology and provides a leakage protector, which has strong safety protection performance, simple structure, reasonable design, can monitor the leakage fault of the power cable in real time and cut off the connection between the power supply and the load, and has a ground The advantage that the line is connected before the fire-zero ...
