Description
Technical field
This utility model belongs to field of electronic devices, particularly relates to a kind of vacuum circuit breaker.
Background technology
Being provided with vacuum interrupter in traditional vacuum circuit breaker, the moving contact of vacuum extinction indoor is by insulation push rod
Drive motion, and push rod is substantially and is connected on drive mechanism.Because operator produce when operating drive mechanism folding
Power the most linearly and inevitably to have influence on the closing speed of contact the most uniform.Closing speed mainly affects the electricity of contact
Abrasion.As closing speed is the lowest, then pre arcing time is long, and the time that electric arc exists is long, and contact surface electrical wear is big, even makes to touch
First melt is welded and is clung, and reduces the electric life of arc-chutes.But speed is the highest, easily producing closing rebound, operating mechanism output work is also
Increase, big to arc-chutes and complete machine mechanical shock, affect dependability and the mechanical life of product.And, use machinery
Structure driven can produce vibrations, and vibrations not only can affect the air-tightness of vacuum interrupter, and between quiet, moving contact can be affected
Contact, easily forms the half-open state narrowed between contact, can cause electric fault time serious.
Therefore, prior art existing defects, need to improve.
Utility model content
In view of this, the purpose of this utility model is i.e. to provide a kind of vacuum circuit breaker.
To achieve these goals, a kind of vacuum circuit breaker provided by the utility model, including support, be arranged on described
Electric magnet, battery component and the wireless switching that three-phase vacuum interrupter on support, armature are mutually matched with described armature,
Described electric magnet, described battery component, described wireless switching and described electric magnet are sequentially connected electrically formation loop, described vacuum
Arc-chutes are provided with the insulation push rod being connected to moving contact, and the end of described insulation push rod is connected on the side of described armature, institute
Stating armature and be connected to support by back-moving spring, described electric magnet is arranged at described armature and connects the back of the body of the side having insulation push rod
Face；When wireless switching closes, electric magnet attracts described armature, and it is described that described armature overcomes the pulling force of described back-moving spring to drive
Insulation push rod disconnecting circuit；This vacuum circuit breaker also includes being arranged at the temperature sensor of the inwall of described vacuum interrupter, bag
Wrap up in a layer of ceramic heat layer and temperature controller on the outer wall being arranged at vacuum interrupter, this temperature controller and described pottery
Porcelain zone of heating and described temperature sensor are electrically connected.
Further, the axle center of described vacuum interrupter constitutes three summits of equilateral triangle.
Further, described moving contact is elastic conduction post.
Further, described wireless switching is infrared switch, Bluetooth switch or radio-frequency (RF) switch.
The vacuum circuit breaker that this utility model provides, owing to being provided with wireless switching, can control this by wireless signal
The switch of vacuum circuit breaker, owing to being provided with temperature sensor, ceramic heat layer and temperature controller, it is possible to achieve to vacuum
The temperature of arc-chutes controls so that this vacuum circuit breaker can also normally use at low ambient temperatures.
Accompanying drawing explanation
Fig. 1 is the structural representation of the vacuum circuit breaker that this utility model embodiment provides.
Detailed description of the invention
