Abstract

The invention relates to an insulated high-voltage switch cabinet, and the switch cabinet comprises a cabinet body which is internally provided with an installation space for the arrangement of electric parts, and is provided with a cabinet door for sealing the installation space; the cabinet body is also provided with a mounting groove; the cooling assembly comprises a heat absorption piece which is arranged on the inner wall of the cabinet body and covers the mounting groove in a sealing mode, and the heat absorption piece is used for absorbing heat in the cabinet body; one part of the heat exchange part is connected with the heat absorption part, and the other part of the heat exchange part penetrates through the mounting groove and extends out of the cabinet body; and the heat exchange piece is used for exchanging heat with the heat absorption piece so as to discharge heat in the cabinet body. Therefore, electric fires caused by too high temperature in the cabinet body are avoided, and the problem that dust and oxygen entering from the vent holes accelerate aging of electric devices in the high-voltage switch cabinet is avoided.

Description

technical field [0001] The present application relates to the technical field of power switchgear, in particular to an insulated high-voltage switchgear. Background technique [0002] With the development of industry, all walks of life have increasing requirements for power supply reliability and stability of the power system. A large number of switchgears are required in the power system to house various control switches or other control equipment, among which high-voltage switches The cabinet plays the role of power generation, power transmission, power distribution, power conversion, on-off, control and protection in the power system. [0003] In related technologies, phenomena such as overload operation and aging of electrical components often occur in the long-term operation of high-voltage switchgear, and these phenomena can easily lead to local temperature rise inside the switchgear, resulting in electrical fires, so ensure that the high-voltage switchgear It is very...
