Problems solved by technology

However, none of the circuit breaker products on the existing market can immediately determine whether there is a fault in the moving and static contacts after the circuit breaker trips, which causes a delay in the diagnosis of the circuit breaker fault

Abstract

The invention provides a circuit breaker with a perspective window, which comprises a circuit breaker shell and a perspective window, wherein the perspective window is in a shape of a transparent sheet; the circuit breaker shell comprises a left part and a right part; the front end surface of the circuit breaker shell is provided with a groove with the consistent outer diameter with the perspective window; and the perspective window and the circuit breaker shell are clamped and fixed through the groove. According to the circuit breaker with the perspective window, after opening of the circuitbreaker happens, whether fault exists in a dynamic or static contact is judged at the first time through the perspective window on the circuit breaker, and the fault of the circuit breaker can be timely diagnosed.

Description

technical field [0001] The invention belongs to the field of circuit breakers, in particular to a circuit breaker with a perspective window. Background technique [0002] Low-voltage circuit breaker, also known as air switch, is mainly used to connect or disconnect the circuit under no-load conditions. The disconnection and closing can be clearly seen through the perspective window, so as to play a safe use of electricity or maintenance, which is convenient for maintenance and has a lock function. It is used to connect or isolate the line and the power supply. After the low-voltage circuit breaker trips due to a fault, it cannot be ended simply by closing the switch, but should be observed first. Because the static contacts, moving contacts, springs, coils, and other components of low-voltage circuit breakers are prone to failure. Determine whether the static contact should be replaced by observing the burn on the surface of the static contact, so as not to reduce the pres...
