Circuit breaker controlled by remote wireless signal

Abstract

The invention discloses a circuit breaker controlled by a remote wireless signal, which comprises a circuit breaker body equipped with a manual control handle, an automatic reclosing mechanism, and a remote signal controller, wherein the automatic reclosing mechanism comprises an outer casing, an automatic control handle, a linkage rod, a reset torsion spring, a coil, a coil bracket, an electromagnet, and an integrated circuit board; the electromagnet is electrically connected with and controlled by the integrated circuit board; an electric leakage time delay protection module, an overvoltage and undervoltage protection module, a rectifying transformation module, and a communication module kept in communication with the remote signal controller are further arranged on the integrated circuit board. Through the structure, a user can remotely control the open and close of the circuit breaker body through a wireless signal, so that the user can control the circuit more conveniently, and the safety and the reliability of electricity using are increased.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a circuit breaker which can be controlled by remote wireless signals. Background technique [0002] The circuit breaker is a current protection device commonly used in the existing low-voltage power grid. Once a short circuit or other fault occurs in the circuit, it will be disconnected in time to protect the safety of the load. However, the reclosing of the existing circuit breaker after disconnection, and the temporary disconnection or closing of the circuit breaker during use require people to go to the scene for manual operation, which not only seems very troublesome, but also It is even more laborious for some circuit breakers that are placed in high places, remote or hidden environments, and there are certain safety hazards in manual operation. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a circuit breaker that can be ...
