Abstract

The invention discloses an all-insulated and all-sealed alternating-current metal closed fixed switch cabinet which comprises a cabinet body. A first partition plate and a second partition plate are transversely arranged in the cabinet body from top to bottom in sequence, and the cabinet body is divided into a cooling bin, a switch bin and an electrical bin which are arranged up and down by the first partition plate and the second partition plate. A third partition plate is vertically arranged between the first partition plate and the second partition plate, the third partition plate divides the switch bin into a gas insulation cabinet and a solid insulation cabinet which are arranged left and right, a cooling assembly is included, a gas control assembly is arranged in the electrical bin, a controller is arranged on the cabinet door, and the cooling assembly comprises a gas cooling assembly and an in-cabinet cooling assembly. The air cooling assembly is arranged, air blown out by an air pump passes through a buffer box, then enters a transverse pipe through an air inlet pipe and is finally exhausted from the right end of the transverse pipe, hot air in the transverse pipe is blown out, the transverse pipe is cooled, the temperature of the air pipe making contact with the outer side of the transverse pipe is reduced, and therefore the effect of cooling air in the air pipe is achieved.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a fully insulated and fully sealed AC metal-enclosed fixed switch cabinet. Background technique [0002] Switch cabinet is a kind of electrical equipment often used in power system. For example, the patent whose authorization number is CN204577973 discloses a solid fully insulated load switchgear, including a shell and a cabinet door, and a load switch, a disconnector, and an operating mechanism are installed inside the shell; connected, the operating mechanism is connected to the load switch and the isolating switch, the load switch is a solid-sealed vacuum load switch, and the isolating switch is a solid-sealed isolating switch. However, this device only cools down by connecting an external oil cooling device, and the cooling method is single. When there is no external oil cooling device, it cannot effectively cool down by itself, and its adaptability is poor. Conten...
