Problems Existing in the Research of Intelligent Circuit Breakers

Although intelligent circuit breakers have many excellent performances, they also face many problems that need to be improved.

First of all, the transition from the traditional mechanized operating mechanism to the electronic operating mechanism makes the reliability of the control loop face the test of the aging of electronic devices and strong electromagnetic interference. The mismatch between the service life of complex electronic equipment and the service life of primary equipment will seriously affect the development of intelligent circuit breakers. Therefore, the fundamental change in the action mode of circuit breakers makes many manufacturers extremely cautious when developing intelligent circuit breaker products.

Secondly, complex intelligent controllers will greatly increase the production cost of intelligent circuit breakers, which also hinders the popularization of such products. Insulation monitoring equipment occupies an important position in intelligent circuit breakers, but its development and production costs remain high.

The intelligentization of circuit breakers is a work of upgrading, which involves technological progress and innovative development in many fields, such as sensor technology, computer technology, microelectronic technology, information technology and electromagnetic compatibility technology, etc., which requires more investment and development. .
