Description

Intelligent vacuum circuit breaker Technical Field The utility model relates to the field of vacuum circuit breakers, in particular to an intelligent vacuum circuit breaker. Background The vacuum circuit breaker is named because the arc extinguishing medium and the insulating medium of the contact gap after arc extinction are both high vacuum, has the advantages of small volume, light weight, suitability for frequent operation and no maintenance for arc extinction, and is more popular in power distribution networks. The vacuum circuit breaker is an indoor distribution device in a 3-10 kV 50Hz three-phase alternating current system, can be used for protecting and controlling electrical equipment in industrial and mining enterprises, power plants and substations, is particularly suitable for use places requiring oilless maintenance and frequent operation, and can be arranged in a centrally installed switchgear, a double-layer cabinet and a fixed cabinet to be used for controlling and protecting high-voltage electrical equipment. The traditional structure is generally lack of a physical isolation or interlocking device, operators can directly contact an operation part, misoperation is easily caused by negligence or misjudgment, such as miscontact of a brake-separating button during brake-on, electrical accidents are caused, the traditional structure is insufficient in tightness, dust, moisture, corrosive gas and the like are easy to invade the interior, the insulation performance is reduced or mechanical jamming is caused, and in a high-temperature, high-humidity or strong electromagnetic interference environment, the traditional structure is easy to cause faults due to material aging or electromagnetic interference. Disclosure of utility model The utility model aims to solve the defect that the protection of a vacuum circuit breaker is inconvenient in the prior art, and provides an intelligent vacuum circuit breaker. In order to solve the problems existing in the prior art, the utility model adopts the following technical scheme: An intelligent vacuum circuit breaker comprises a protective frame, a vacuum circuit breaker body, a protective plate and a convenient-to-detach assembly; A vent is arranged at one side of the protective frame; The vacuum circuit breaker body penetrates through the top of the protection frame; the protection plate is embedded with the protection frame; The convenient-to-detach assembly is arranged in the protection plate and comprises a limiting mechanism used for fixing the protection plate and a transmission mechanism used for driving the limiting mechanism to move, wherein the limiting mechanism comprises limiting plates, and the two limiting plates are arranged on the protection plate in a sliding manner and are clamped with the protection frame.
