Integral electronic module of intelligent molded case circuit breaker

Abstract

The invention discloses an integral electronic module of an intelligent molded case circuit breaker, and the integral electronic module comprises a box type support capable of being integrally plug-in connected or fixed in a case of the molded case circuit breaker, a magnetic flux convertor, a plurality of electronic transformers and a circuit board, wherein the circuit board is fixed at the top part of the box type support, the magnetic flux converter is arranged in the middle part of the box type support, the plurality of the electronic transformers are arranged in the bottom part of the box type support in parallel, the outputs of all the electronic transformers are connected with the input of the circuit board respectively, and the output of the circuit board is connected with the magnetic flux converter. By integrating the magnetic flux converter, the electronic transformers and the circuit board into one module, on the one hand, the disadvantage that the structure of the circuitboard is not compact because the structures of electronic devices in the prior art are dispersed is solved, on the other hand, the electronic devices for the circuit breaker have the characteristics of being convenient for disassembly and assembly, convenient to test and convenient to maintain.

Description

technical field [0001] The invention relates to an intelligent molded case circuit breaker, in particular to an integral electronic module of the intelligent molded case circuit breaker. Background technique [0002] Molded case circuit breaker is a kind of circuit breaker. Molded case refers to the use of plastic insulators as the casing of the device to isolate conductors and grounded metal parts. Molded case circuit breakers are generally used for power distribution and can also be used to protect motors. Molded case circuit breakers can be installed in the line to protect the load equipment. When there are abnormal phenomena in the line, such as leakage, overload or short circuit, the molded case circuit breaker The circuit breaker can cut off the power supply to the load equipment in time to achieve the purpose of protecting the line, load equipment and personal safety. Intelligent molded case circuit breakers usually include housings, releases, contact parts, flux con...

AI Technical Summary

Problems solved by technology

In the existing molded case circuit breaker, the electronic components are respectively installed in different positions of the housing, that is, the magnetic flux converter, the electronic transformer and the circuit board are respectively installed in different positions of the housing. This structure mainly brings The disadvantages are as follows: first, the structure of the electronic device is scattered, resulting in an uncompact structure; second, the disassembly and assembly of the electronic device is inconvenient; third, it is not convenient to test the electronic device. When testing, the entire molded case circuit breaker needs to be It is used for testing; Fourth, it is not convenient for the maintenance of electronic devices. When an electronic device fails, the entire molded case circuit breaker needs to be disassembled
