Abstract

The invention discloses an insulating switch cabinet, which comprises a switch cabinet body, wherein the switch cabinet body comprises a steel plate layer, an insulating layer and a protection surfacelayer; the insulating layer is arranged on the inner wall of the steel plate layer, and the protection surface layer is arranged on the outer wall of the steel plate layer. According to the insulating switch cabinet disclosed by the invention, the inner wall of the steel plate is provided with the insulating layer, the insulating performance and the heat-proof and weather-proof performance of theswitch cabinet body can be greatly improved, and the use safety of the switch cabinet body is improved; the outer surface of the steel plate layer is provided with the protection surface layer, so that the mechanical strength, the weather fastness and the stability of the switch cabinet body can be improved, effective protection can be formed for the switch cabinet body, and the service life of the switch cabinet is prolonged. The invention also can carry out real-time monitoring on temperature and current situations in the switch cabinet body, and the safety performance of the switch cabinetcan be further improved.

Description

technical field [0001] The invention relates to the field of switchgear equipment, in particular to an insulating switchgear. Background technique [0002] Switchgear is an important device in the power system and is widely used in various industries. Switchgear or power distribution cabinet is the collective name of the motor control center, which is the final equipment of the power distribution system; the power distribution cabinet is used in occasions with concentrated loads and many circuits, and is responsible for distributing the power of a certain circuit of the upper-level power distribution equipment Give the nearest load. [0003] However, the insulation performance and weather resistance performance of the existing switch cabinets are difficult to meet the requirements, and there are great potential safety hazards, and the service life is short. Therefore, it is necessary to provide an insulating switchgear to solve the above problems. Contents of the inventi...
