Abstract

The invention provides a position limiting device for a drawer unit of a pull-out type low-voltage switch cabinet. Two fixed grooves are fixedly fomred in a position of each drawer in a cabinet body of a drawer cabinet, a support frame is arranged at the outer side of the two fixing grooves, a plurality of pulleys are arranged between the support frame and the fixing grooves, the support frame slides along the fixing grooves through the pulleys, the pull-out ends of the two fixing grooves are respectively provided with position limiting blocks, and drawer are hung on the support frame. The position limiting device has the following advantages and beneficial effects that 1, the drawer unit can be effectively prevented from generating sliding-down or sliding-out phenomenon; 2, the position limiting device is used for hanging the drawers on the support frame, and the drawers cannot generate the slide-down phenomenon even when the drawers slide out of the fixing grooves; 3, the structure is simple, and the use is convenient.

Description

Technical field: [0001] The invention belongs to a low-voltage complete switchgear, in particular to a drawer unit limiting device of a drawer-type low-voltage switchgear. Background technique: [0002] There are many types of low-voltage complete switchgear, and the structure is quite different. Among them, the structure of the withdrawable low-voltage switchgear is the most complicated. Withdrawable low-voltage switchgear is composed of compartments such as busbar area (horizontal busbar and vertical busbar), cable area and functional unit area. Several functional units, namely drawer units, are installed in the functional unit area. A functional unit is connected by several electrical components and installed in a replaceable structural unit, which is called a drawer. [0003] The drawer unit generally needs to set the working position, test position, separation position and withdrawal position. When designing the operation mode of the drawer, it is often necessary to ...
