Electrical cabinets with variable-volume mounting chambers

Abstract

The invention relates to electrical equipment, and discloses electrical device placement equipment with a variable-volume installation cavity. The electrical device placement equipment comprises an equipment body (1), wherein a volume expansion body (3) is arranged in the equipment body (1), can extend out of a front end surface of the equipment body (1) and do linear motion in a reciprocating wayalong a width direction of the equipment body (1), the volume expansion body (3) is a rectangular frame, the rectangular frame comprises four side plates, and a door body (4) is arranged at a front end surface. By arranging the volume expansion body (3) capable of stretching and contracting in the equipment body (1), the internal volume of the whole equipment body (1) is changed, the applicationrange of the equipment is expanded, so that the equipment can be reasonably arranged, and the demand is fully satisfied.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to an electrical device placement equipment. Background technique [0002] Electrical device placement equipment includes electrical cabinets, control cabinets, and electrical boxes. It is a cabinet made of steel to protect the normal operation of components.

[0003] The general structure of the electrical device placement equipment is composed of an external shell and an internal bracket. The internal bracket is used to place various components, and is generally in the shape of a cuboid. Due to the large number of components inside, the overall volume is large, which is relatively large for the working space. This type of electrical cabinet can fully meet the needs of large factories or workshops, but for some factories or workshops with small working space, some larger electrical cabinets are difficult to arrange reasonably, while smaller electrical cabinets cannot meet the demand
