Internet of things miniature circuit breaker

Abstract

The invention relates to an internet of things miniature circuit breaker which comprises a shell, a circuit breaker unit, an electric operating mechanism and an intelligent control circuit board, and is characterized in that the circuit breaker unit comprises an operating mechanism, an L-line contact assembly, an N-line contact assembly and a bimetallic strip tripping mechanism, and the operating mechanism comprises an operating handle, a support, a tension spring, a lock catch, a torsion spring and a jump pin; a pull rod is arranged between the jump pin and the operation handle and forms the linkage matching of the jump pin and the operation handle, the L-line contact assembly comprises an L-line moving contact and an L-line static contact, and a first torsion spring is arranged between the L-line moving contact and the support; the N-line contact assembly comprises an N-line moving contact arranged at the other side of the support in a linkage mode and an N-line static contact matched with the N-line moving contact, a second torsional spring is arranged between the N-line moving contact and the support, and a double-coil electromagnetic tripping mechanism matched with the lock catch is arranged in the shell. The internet of things miniature circuit breaker of the invention has the advantages of simple structure, stable and reliable performance, small volume and high breaking capacity.

Description

Technical field[0001]The present invention relates to the field of circuit breaker, and more particularly to an Internet of Things small circuit breakers.Background technique[0002]At present, small circuit breakers are widely used in low-voltage distribution networks, mainly used in various places such as industrial, commercial, high-level and civil houses, can overcurrently protect and leak electricity for electric vehicles, distribution lines, lighting circuits. protection. The traditional small circuit breaker is divided, the closing action, which requires manual manual operation. With the development of my country's smart grid, under the premise of the safety operation of the grid, the intelligence of the control appliance is increasingly eager. In order to cope with the new situation, the existing small circuit breaker should have an automatic reclosing function. The electric operating mechanism of the small circuit breaker is a communication remote control or by the CPU progra...

AI Technical Summary

Problems solved by technology

The existing Internet of Things miniature circuit breaker includes a circuit breaker unit and an automatic reclosing device assembled with the circuit breaker unit. The circuit breaker unit of the existing Internet of Things miniature circuit breaker includes a neutral line circuit breaker module, a live line circuit breaker The wire circuit breaker module and the live wire circuit breaker module respectively need two sets of operating mechanisms to control the opening or closing of the circuit breaker, so the IoT circuit breaker has the defects of complex structure, large volume, low reliability, and weak breaking capacity
