Electric leakage circuit breaker

Abstract

The invention provides an electric leakage circuit breaker, which comprises an L-phase pole module, an N-phase pole module, a reclosing pole module and electric leakage protection modules, wherein the electric leakage protection modules are arranged in the N-phase pole module and the reclosing pole module in a dispersed mode, the electric leakage protection modules are provided with test button loops, the on-off of the test button loops is controlled by test buttons arranged on the reclosing pole module, an indicating lamp is arranged on the circuit board of the reclosing pole module, and comprises a test button arranged on the reclosing pole module in a penetrating mode and a light-emitting element arranged in the reclosing pole module, and the test button is arranged near the light-emitting element, and is used as a light guide column to guide the working state of the light-emitting element out of the reclosing pole module for displaying the working state of the circuit breaker. According to the structure of the test button serving as the light guide column of the indicating lamp, when the test button is pressed, the indicating lamp does not pop up, and the size of the circuit breaker can be reduced.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a leakage circuit breaker. Background technique [0002] Leakage circuit breakers are mainly used to protect electrical appliances to prevent personal electric shock and electrical fires when the circuit or electrical insulation is damaged and short-circuited to ground. Existing leakage circuit breakers are provided with test devices for simulating leakage actions, but such test devices occupy a large space in the circuit breaker, which is not conducive to the miniaturization design of the product, and has defects such as unreliable contact. In addition, the existing leakage circuit breaker also has a leakage indication device. Usually, two buttons are arranged on the circuit breaker, one is a leakage test button, and the other is a leakage indication button; the traditional leakage indication button adopts a mechanical interlock device. After the circuit breaker trips due to a leakage fault...

AI Technical Summary

Problems solved by technology

The existing leakage circuit breaker is equipped with a test device for simulating leakage action, but because this test device occupies a large space in the circuit breaker, it is not conducive to the miniaturization design of the product, and there are defects such as unreliable contact

In addition, the existing leakage circuit breaker also has a leakage indication device. Usually, two buttons are arranged on the circuit breaker, one is a leakage test button, and the other is a leakage indication button; the traditional leakage indication button adopts a mechanical interlocking device. After the circuit breaker trips due to leakage fault, the indicator will act to indicate the leakage trip of the circuit breaker. This method of separately setting the indicator and the test button is not conducive to the miniaturization of the circuit breaker
