Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an action circuit breaker that utilizes residual current combined with magnetization traction and cutting warning to solve the problem that the air circuit breaker only simply protects the circuit, and after a long time of use, the aging phenomenon of parts will occur, which is easy to The transmission of the tripping parts is blocked. It seems that the switch shaft has jumped on the surface, but the actual internal parts still make the live wire and the neutral wire connected. That is, the circuit breaker leaks electricity and does not respond to the open circuit warning device, which is likely to cause electric shock to the user. life-threatening problems

Abstract

The invention discloses an operated circuit breaker using a residual current to cooperate with magnetized traction cutting warning. The structure comprises an electric connecting rod, an air circuit breaker, a disconnection start lever, and a current traction device. Through using main contact bounce during disconnection, an extrusion screw rod is connected to the electric connecting rod, and a movable magnetization device and a null line complete a closed loop. At this time, if the air circuit breaker is in an electric leakage state, a current on a null line is transmitted to a fixed verticalrod through the electric connecting rod, and a magnetization coil generates a strong magnetic field so as to attract an electromagnetic block to carry out magnetic induction line cutting motion, realize an alarm light flash action, and remind a user of electric leakage of the air circuit breaker. A hidden danger of electric shock is maximumly avoided and accidents are prevented. Due to an unstable leakage current voltage after disconnection, there is a large fluctuation. At this time, an attractive force of a magnetization coil continuously changes. Under pulling of a telescopic rod, the magnetic induction line cutting motion can be continuously or intermittently performed so as to avoid directly connecting between alarm light and a main circuit and prevent a large current after the electric leakage from being directly connected to the alarm light.

Description

technical field [0001] The invention relates to an action circuit breaker which utilizes residual current and coordinates magnetization traction and cutting alarm, and belongs to the field of household circuit breakers. Background technique [0002] As one of the essential energy sources in daily life, electric energy is divided into live wire and neutral wire when connected. The two are connected through an air circuit breaker. When the current is too large, the air circuit breaker will automatically pass through a series of mechanical transmissions. , to separate the live wire from the neutral wire to achieve protection. However, when the air circuit breaker is aging or the parts are stuck, the switch rotation axis will recover at this time, but the actual live wire and the neutral wire are still connected. [0003] However, the existing circuit breakers have the following disadvantages: [0004] The air circuit breaker simply protects the circuit. After a long time of us...
