Problems solved by technology

In this case, a safety accident may occur, for example, the breaker body falls before a part of the breaker body is inserted and the worker is injured, etc.
[0010] In addition, when the breaker body is drawn out from the inside of the case, that is, when the breaker body is separated from the inside of the case, if the breaker body is completely separated from the inside of the case at one time, it may occur that the breaker body falls. Safety accidents in which it falls on the operator and injures the user, etc.

Abstract

The invention relates o a circuit breaker. According to one embodiment of the invention, the circuit breaker may includes: a housing; a circuit breaker body which is connected to the housing; and at least one of a slide unit and a body anti-disconnection portion, wherein the slide unit is connected to the circuit breaker body and can match a railway arranged on the housing to move so as to allow the circuit breaker body to move, and the body anti-disconnection portion is arranged on the housing and is configured to be clamped on the circuit breaker body so as to prevent disconnection of the circuit breaker from the housing.

Description

technical field [0001] The present invention relates to a circuit breaker (CIRCUIT BREAKER), more particularly, relates to a circuit breaker with a guide rail or when the circuit breaker body is drawn out from the case, the circuit breaker body cannot be separated from the case at one time. Background technique [0002] When a fault occurs in a power system, a high fault current equivalent to dozens of times the rated current may flow due to a sharp decrease in load resistance. In order to prevent the spread of the fault area and damage to other devices in the event of a power system accident, it is necessary to cut off the fault current by itself quickly. [0003] The circuit breaker used in this case is a device that automatically cuts off the circuit to prevent damage caused by overload or short circuit in the circuit. The reliability of the circuit breaker has a core influence on the reliability of the entire system. [0004] In particular, among such circuit breakers, ...
