Problems solved by technology

Because the cabinet type is a welded structure, not only the production cycle is long, the structural error is large, and the welding stress cannot be avoided, but also the size of the cabinet body is large, the feudal investment of the power distribution room is large, and the installation, maintenance and repair of the main components in the cabinet are very inconvenient.
In addition, the cabinet type has poor anti-corrosion performance; the protection level is only IP2X, and the protection level is low; the reliability of the five-proof locking is poor and the operation is difficult

Abstract

The present invention relates to a metal-clad movable metal-enclosed switchgear, which comprises a housing, a clapboard that surround the housing to be closed space of a bus-bar room, a cart room, a electric relay meter cabinet and a cable house; a circuit breaker cart is set in the cart room; the housing and the clapboard are made of Al-Zn coated steel sheet and they two riveted as a whole after bending; the circuit breaker cart is disposed on the chassis. The housing and the insulating clapboard in the invention is assembled but not welded with good-look appearance, welding stress is avoided, furthermore, the present invention is secure and reliable in use, and has good protective performance.

Description

technical field [0001] The invention relates to an armored removable metal-enclosed switchgear. Background technique [0002] At present, the cabinet frame of XGN17-40.5 box-type fixed AC metal-enclosed switchgear is welded by angle steel. The cabinet is divided into circuit breaker room, busbar room, cable room, relay room, etc., and the rooms are separated by steel plates. Because the cabinet type is a welded structure, not only the production cycle is long, the structural error is large, and the welding stress cannot be avoided, but also the size of the cabinet body is large, the feudal investment of the power distribution room is large, and the installation, maintenance and repair of the main components in the cabinet are very inconvenient. In addition, the cabinet type has poor anti-corrosion performance; the protection level is only IP2X, which is low; the five-proof locking has poor reliability and difficult operation. Contents of the invention [0003] The object ...
