Description

half drawer unit

technical field

The utility model patent relates to switch cabinet components, in particular to a half-drawer unit.

Background technique

The drawer-type switch cabinet is made of steel plate to make a closed shell, and the electrical components of the incoming and outgoing circuit are all installed in the drawer, which constitutes a functional unit that can complete a certain type of power supply task. The functional unit is separated from the bus bar or cable by a grounded metal plate or a plastic functional plate to form three areas: bus bar, functional unit and cable. There are also isolation measures between each functional unit. Drawer-type switchgear has high reliability, safety and interchangeability, and is a relatively advanced switchgear. Most of the switchgears currently produced are drawer-type switchgears. They are suitable for industrial and mining enterprises and high-rise buildings that require high reliability of power supply, as a centralized control power distribution center.

The drawer type switch cabinet is usually equipped with a primary connector and a secondary connector. The primary connector mainly refers to the connector used on the primary line in the power distribution cabinet. The circuit conduction is completed through the insertion of the dynamic and static plug-in. The secondary control circuit in the distribution cabinet.

The secondary plug-in in the existing switch cabinet is installed on the drawer of the switch cabinet. The circuit of the secondary plug-in is controlled by the interlock device, which takes up a lot of space, resulting in fewer electrical components and fewer functions. The arrangement is tight and cannot effectively dissipate heat.

Utility model content

The technical problem to be solved and the technical task proposed by the utility model are to improve the prior art and provide a half-drawer unit. The utility model has the advantages of small space occupation, simple structure and convenient maintenance.

In order to solve the above technical problems, the technical solution of the utility model is that a half-drawer unit includes a mounting frame, the mounting frame is arranged on the guide rail in the switch cabinet, and the primary plug-in and the secondary plug-in are connected to the mounting frame , the primary plug-in is electrically connected to the secondary plug-in.

Preferably, both ends of the installation frame are provided with support grooves along the horizontal direction, and the support grooves are embedded on the guide rails in the switch cabinet.

Preferably, the mounting bracket includes a "C"-shaped bracket and a detachable flat plate, and the flat plate is installed on the opening side of the "C"-shaped bracket.

Preferably, a wire hole is provided on the plate, and a wire passes through the wire hole, and the wire connects the primary plug-in and the secondary plug-in.

Preferably, the primary plug-in is provided with an insulating shell, the insulating shell is provided with a convex groove, and the mounting frame is provided with a groove, and the convex groove of the primary plug-in is mated with the groove on the mounting frame .

According to the utility model, one side of the mounting frame is a detachable mounting plate, which has the advantage of convenient maintenance. The interlocking structure saves the layout space in the switch cabinet, and has the advantages of compact structure, reasonable layout and small space occupation.

The utility model provides a half-drawer unit, which has the advantages of small occupied space, simple structure and convenient maintenance.
