Description

technical field [0001] The invention relates to a 24kV central switchgear. Background technique [0002] Compared with the 10kV voltage level system, the current 20kV voltage level system has the advantages of wide power supply range, low line loss, and less equipment investment. With the rapid development of China's power grid, many areas have begun to build 20kV voltage level power grids, but the current 20kV switchgear has a complex structure, relatively large devices, and relatively poor safety performance. Contents of the invention [0003] The invention provides a 24kV mid-mounted switchgear, which not only has a simple structure, strong versatility, is convenient for maintenance, but also has good safety performance. [0004] The present invention adopts the following technical solutions: a 24kV mid-mounted switchgear, which includes a cabinet body, in which a handcart room, a busbar room, a cable room and a relay instrument room are distributed, and the relay inst...
