Rainproof electric leakage breaker

Abstract

A rainproof electric leakage breaker disclosed by the present invention comprises a closing handle, a rainproof cover and an action chamber, a handle chute is arranged at the upper side of the closing handle, and a lower contact fastening screw is arranged at the lower side of the closing handle. A lower incoming line chamber is arranged at the lower side of the lower contact fastening screw, a ceramic clapboard is arranged at the inner side of the handle chute, and an upper contact fastening screw is arranged at the upper side of the handle chute. The rainproof cover is arranged at the top of a device, and an inclined incoming line hole is arranged at the front end of the rainproof cover, so that a circuit generates a downward arc when being arranged and installed, and the rainwater drops to the outer side of the breaker along the arc when dropping along the circuit, and does not enter the breaker along the circuit, and accordingly, the usage reliability of the breaker at rainy day is guaranteed. Moreover, the ceramic clapboards are arranged between the breakers, so that when one circuit goes wrong, the normal operation of the whole breaker is not influenced, and the normal power consumption of the residents is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a rainproof leakage circuit breaker. Background technique [0002] Leakage circuit breaker is a switch that can automatically operate when the leakage current in the circuit exceeds a predetermined value. Commonly used leakage circuit breakers are divided into voltage type and current type, and current type is divided into electromagnetic type and electronic type. Leakage circuit breakers are used to prevent personal electric shock, and should be selected according to the different requirements of direct contact and indirect contact protection against electric shock. [0003] Some of the original circuit breakers need to be installed in the outdoor meter box, but the rainproof facilities above may be damaged by external force after a long time. Sometimes, rainwater will slowly drip along the line to the meter and circuit breaker, causing the circuit breake...

AI Technical Summary

Problems solved by technology

[0003] Some of the original circuit breakers need to be installed in the outdoor meter box, but the rainproof facilities above may be damaged by external force after a long time. Sometimes, rainwater will slowly drip along the line to the electric meter and circuit breaker, causing the circuit breaker to trip and cut off the power supply, affecting the normal electricity consumption of citizens.
