Remote-control air circuit breaker

Abstract

The invention discloses a remote-control air circuit breaker, which comprises a hollow shell with an opening in one side, wherein two baffle plates which are arranged at an interval along the verticaldirection are arranged in the shell; the baffle plates divide the inside of the shell into a first placement groove, a second placement groove and a third placement groove; an automatic circuit breaker and an alarming apparatus are arranged in the first placement groove; a circuit switch is arranged in the second placement groove; a remote control opening and closing device is arranged in the third placement groove; a first rotating shaft which is connected with the automatic circuit breaker, the circuit switch and the remote control opening and closing device at the same time is arranged inthe shell; the automatic circuit breaker device is capable of automatically stirring the circuit switch to cut off a power supply; and the remote control opening and closing device is capable of remotely controlling power-off or power-on. The invention aims at providing the remote-control air circuit breaker which integrates automatic power-off, remote control power-off and remote control power-onand is capable of giving an alarm after automatic power-off.

Description

technical field [0001] The invention relates to the technical field of circuit breaker equipment, in particular to a remote-controlled air circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch. Combination with overheating and underheating relays, etc. Moreover, there is generally no need to change parts after breaking the fault current. At present, it has been widely used. [0003] The common circuit breakers on the market generally need to be manually reset after the circuit is br...

AI Technical Summary

Problems solved by technology

[0003] The common circuit breakers on the market generally need to be manually reset after the circuit is broken. Not only is it troublesome, but also there may be a danger of leakage, accidents, and personal safety. In addition, after the circuit is automatically powered off due to a short circuit, a reminder signal cannot be issued.
