Mounting structure of standby protective module of breaker replacement controller

Abstract

A mounting structure of a standby protective module of a breaker replacement controller comprises a circuit breaker (1) and is characterized in that a signal switching device (3) disposed inside a controller base (2) of the circuit breaker (1) can switch protective function control signals of the circuit breaker (1) between a controller (4) and the standby protective module (5). The mounting structure has the advantages that the circuit breaker is protected during controller replacement; once distribution lines short, the standby protective module immediately transmits a closing signal to the circuit breaker to break the circuit breaker; burnout of the circuit breaker is avoided, and the breaker replacement controller is safer.

Description

technical field [0001] The invention belongs to the technical field of circuit breakers, and specifically relates to a circuit breaker replacement controller protection module installation structure, which is used to protect the circuit breaker when the main circuit of the circuit is powered off and the circuit breaker replacement controller is operated. Trip the circuit breaker in the event of a short-circuit fault, enhancing safety. Background technique [0002] Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Low-voltage circuit breaker, also known as automatic switch, commonly known as "air switch", also refers to low-voltage circuit breaker. It is an electrical appliance that not only has the function of manual switch, but also can automatically protect against voltage loss, undervoltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors i...

Problems solved by technology

[0004] The purpose of the present invention is to provide a circuit breaker for the existing circuit breaker in the process of replacing the controller, the circuit breaker is in an unprotected state, and once the distribution line is disconnected, the circuit breaker will be burned out or even a safety accident will occur Replacing the installation structure of the controller protection module can protect the circuit breaker when the controller is replaced. Once a short circuit occurs in the distribution line, the protection module will issue a circuit breaker opening command, which avoids the occurrence of circuit breaker burnout and improves Safety of Circuit Breaker Replacement Controllers
