Dense switch cabinet group

Abstract

The invention relates to a dense switchgear group, comprising a cylindrical cabinet group shell, the top of which is closed by a fixed plate, and the bottom is closed by a rotating chassis, and the rotating chassis is driven to rotate by a stepping drive device; the cylindrical cabinet group There is a sealed opening and closing door body on the front of the shell; multiple sealed switch cabinets are installed on the rotating chassis in a divergent shape; any sealed switch cabinet can be driven by a linear drive device to move back and forth in the direction of divergence to the sealed opening and closing door Outside the body; at the initial position, there is a slit between two adjacent sealed switch cabinets; the cold air for heat dissipation of the sealed switch cabinets enters from the side of the sealed switch cabinet close to the center line of the shell of the cylindrical cabinet group, and from the side close to the cylindrical cabinet The sealed switch cabinet on the side wall of the cabinet group shell is exported from the other side; in the case of occupying a small space, it can realize a good guarantee for the inspection space of the maintenance personnel, the heat dissipation effect of the switch cabinet is good, and it can save energy significantly; Maintenance safety.

Description

technical field [0001] The invention relates to a dense switch cabinet group and belongs to the field of electrical equipment. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs; the main function of the switch cabinet is to generate, transmit, distribute and In the process of power conversion, switch, control and protect electrical equipment. [0003] When the switchgear is running, because there are many heating components in the cabinet, the excessive temperature rise will cause the mechanical and electrical properties of the electrical appliances to decline, and finally lead to the failure of the high-voltage electrical appliances, and even cause serious accidents. In order to ensure the safe operation of high-voltage electrical appliances within the working life, th...

Problems solved by technology

[0004] In addition, there are many switch cabinets concentrated in power distribution rooms in factories, communities, buildings, etc. Due to the need for maintenance, each switch cabinet needs to leave enough space for maintenance personnel to operate. Therefore, the entire power distribution room requires a large space , First, it takes up valuable space, second, it is easy to cause mess and confusion during the maintenance process; third, it consumes a lot of energy to dissipate heat for the entire power distribution room
