Abstract

The invention provides a drawer type switch cabinet which comprises a cabinet body and a drawer arranged in the cabinet body. The draw comprises a drawer body; a molded case circuit breaker which comprises a circuit breaker body and a plurality of first conductive pieces arranged on one side of the wire inlet end of the circuit breaker body, wherein the length extension direction of the circuit breaker body is the same as the extraction direction of the drawer; and plug-in assemblies which are arranged on one side of the wire inlet end of the circuit breaker body and extend out of the drawer body, wherein the plug-in assemblies are connected with the first conductive pieces and are suitable for being in plug-in connection with a wire inlet busbar, since the circuit breaker body is installed in the drawer body in the length direction of the circuit breaker body same as the draw-out direction of the drawer, the wire inlet end of the circuit breaker body extends out of the drawer body, therefore, the widths of the drawer and the cabinet body are greatly reduced, sheet metal materials for manufacturing the drawer and the cabinet body are saved, switching copper bars are reduced, the temperature rise in the drawer is reduced, the production cost is also reduced, and meanwhile, the occupied area of a power distribution room for placing the cabinet body is also greatly reduced.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a drawer type switch cabinet. Background technique [0002] The drawer-type switch cabinet is a closed shell made of steel plate. The electrical components of the incoming and outgoing circuit circuits are installed in drawers that can be drawn out. As a centralized control distribution center, the drawer-type switch cabinet has high reliability, safety and interconnection. It is widely used in industrial and mining enterprises and high-rise buildings that require high power supply reliability. [0003] Existing drawer type switchgear, such as Figure 27-29 As shown, it includes a cabinet body and a drawer that can be drawn out from the cabinet. The drawer includes a drawer body 100, a first panel 101 and a second panel 102 that are respectively arranged on the front and rear sides of the drawer body 100, and the first panel 101 is provided with an operating handle. 103,...
