Abstract

The invention discloses an armoured central alternating-current closed metal switch cabinet which comprises a cabinet body. A cable chamber and a component cavity are arranged in the cabinet body. The cable chamber is arranged on one side of the component cavity, a bus chamber is arranged inside the cable chamber and close to the top of the cabinet body, an instrument chamber, a breaker chamber and an observation room are sequentially arranged in the component cavity from top to bottom, and a first pressure release channel, a second pressure release channel and a third pressure release channel are arranged at the top of the cabinet body, wherein the first pressure release channel is communicated with the cable chamber and used for conducting pressure releasing on the cable chamber, the second pressure release channel is communicated with the bus chamber and used for conducting pressure release on the bus chamber, and the third pressure release channel is communicate with the breaker chamber and used for conducting pressure release on the breaker chamber. Due to the fact that the pressure release channels which are communicated with the breaker chamber, the bus chamber and the cable chamber respectively are arranged at the top of the cabinet body, internal pressure can be released as quickly as possible when the switch cabinet breaks down. Thus, it is guaranteed that the switch cabinet is not damaged, and meanwhile, the working safety of an operator is also guaranteed.

Description

technical field [0001] The invention relates to a power distribution cabinet, in particular to an armored middle-mounted AC metal-enclosed switch cabinet. Background technique [0002] Switchgear is a commonly used equipment in power transmission and distribution of power grids. It is widely used in power plants, small and medium-sized generators for power transmission, power distribution for industrial and mining enterprises, and secondary substations in power systems for power reception, power transmission and large-scale High-voltage motor starting, etc., are mainly composed of cabinets and their internal functional parts. Due to structural problems, large volume, inconvenient installation and maintenance, short service life, and potential safety hazards, its improvement and innovation are problems that the industry hopes to solve. Contents of the invention [0003] The object of the present invention is to provide an armored mid-mounted AC metal-enclosed switchgear, w...
