Combined low-voltage control switch cabinet

Abstract

The invention belongs to the technical field of low-voltage control switch devices and particularly relates to a combined low-voltage control switch cabinet. The combined low-voltage control switch cabinet is safe in use and convenient to operate and overhaul. The technical scheme is that the combined low-voltage control switch cabinet comprises a cabinet body and is structurally characterized in that a main bus chamber is arranged at the upper end of the cabinet body, a switch chamber is arranged at the front portion of the cabinet body, a cable chamber is arranged at the side portion of the cabinet body, an auxiliary bus chamber is arranged at the rear portion of the cabinet body, and a vertical auxiliary busbar in the auxiliary bus chamber is connected with a transverse main busbar in the main bus chamber. The switch chamber comprises multiple vertically-arranged switch cavities, wherein each switch cavity comprises a fixed support box, a movable support box is arranged on the front side of the fixed support box, a vertical busbar provided with a plug at the front end is fixed to the fixed support box and connected with the auxiliary busbar, and a plugging-connection chuck is arranged on the movable support box, corresponding to the plug of the vertical busbar, and is connected with the input end of a breaker through an inner side current guide bar.

Description

technical field [0001] The invention belongs to the technical field of low-voltage control switch devices, and in particular relates to a combined low-voltage control switch cabinet. Background technique [0002] Based on the continuous development of the power industry, higher requirements are put forward for the power distribution system. High protection, uninterrupted power supply, independent cavity formation of each sub-circuit, and minimized circuit fault range have become higher requirements for products in the market. [0003] The existing low-voltage power distribution cabinet is a frame-type box structure. Various components in the cabinet share a box. When a sub-circuit fails, other components in the same box will be affected by it. If the circuit needs to be replaced, it needs to be replaced. It can be overhauled only after the main circuit switch is disconnected, which will expand the scope of the fault. How to divide the circuit to seal the cavity and how to a...

Problems solved by technology

[0003] The existing low-voltage power distribution cabinet is a frame-type box structure. Various components in the cabinet share a box. When a sub-circuit fails, other components in the same box will be affected by it. If the circuit needs to be replaced, it needs to be replaced. It can be overhauled only after the main circuit switch is disconnected, which will expand the fault range

How to divide the circuit to seal the cavity and how to avoid affecting other adjacent circuits in the event of an accident have always been the difficulties in the design of the cabinet; when a circuit in the cabinet needs to be overhauled in the traditional cabinet, the main switch must be disconnected before maintenance. As a result, the power supply of adjacent circuits in the same cabinet is affected. How to realize the maintenance of sub-circuits without affecting the adjacent circuits is a difficult point in cabinet design
