Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0024] In addition, in t...

Abstract

The invention discloses a circuit breaker with an earthquake protection function. The circuit breaker comprises a circuit breaker body and an earthquake sensing protection mechanism. When an earthquake occurs, the overhanging end of a second touch plate vibrates along with the earthquake, the second touch plate is in lap joint with a first touch plate, and at the moment, the circuit is switched on. Due to the fact that a permanent magnet is arranged on the second contact plate, the first contact plate and the second contact plate are in magnetic contact for a long time through the magnetic attraction effect, and the circuit is continuously connected. Because electric equipment is not connected into the circuit, short circuit is caused, the circuit short circuit triggers the open circuit protection of the circuit breaker body, the tripping is caused, and the overall circuit is cut off. A common circuit breaker cannot actively break a circuit when an earthquake occurs, an electric wire is possibly damaged in the earthquake process, the circuit still supplies power at the moment, and an escaper or a rescuer is easily injured. According to the circuit breaker with the earthquake protection function, circuit breaking is actively achieved when an earthquake occurs, a power source is cut off, and therefore casualties caused by electric leakage are avoided.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker with an earthquake protection function. Background technique [0002] A circuit breaker is 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. [0003] 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 or short-circuited or under-voltage. However, when an earthquake occurs, the existing circuit breaker cannot actively cut off the power, which brings potential safety hazards for earthquake escape and rescue operations. Contents of the invention [0004] The main purpose of the present invention is to provide a circuit breaker with an earthquake protection function, ...
