Abstract

This utility model discloses an intelligent medium-voltage switchgear cabinet door limiting device. The device is to add a retractable rod to the original switchgear cabinet door. When the switchgear cabinet door is opened, the retractable rod limits the door and also provides support. When maintenance personnel are present, it can prevent the cabinet door from closing automatically due to its own weight or other external forces.

Description

Cabinet door limit device for intelligent medium voltage switchgear

technical field

The utility model relates to a cabinet door limiting device of an intelligent medium voltage switchgear.

Background technique

With the expansion of the scope of use of medium-voltage switchgear, higher requirements are put forward for the details of use. In the past, the doors of medium voltage switchgear were not particularly perfect. There is often the phenomenon that the instrument door is automatically closed due to its own gravity, which causes inconvenience to the maintenance personnel.

Contents of the invention

The purpose of this utility model is to provide a cabinet door limit device of an intelligent medium voltage switchgear that prevents the instrument door from being automatically closed due to its own gravity or other external forces.

In order to achieve the above purpose, the cabinet door limit device of the intelligent medium voltage switchgear of the utility model is a retractable rod type device, which is composed of a helical compression spring, a stretchable rotating shaft connected to the door and a mounting piece. .

The utility model is installed on the original equipment cabinet door that can be moved at will, and the cabinet door is limited, and it can play a supporting role when it is opened. When the maintenance personnel are present, the cabinet door can be prevented from being broken due to its own gravity or other external forces. Automatically shuts off.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described in detail:

Fig. 1 is the position figure that the utility model is installed.

Fig. 2 is a structural schematic diagram of the utility model.

Detailed ways

In Fig. 1, 1 is an intelligent medium-voltage switchgear, 2 is the front lower door of the equipment, and 3 is the position indication of the installation of the utility model.

In Fig. 2, the utility model is a kind of retractable rod-type device, which is composed of a helical compression spring 4, a stretchable rotating shaft 5 connected to the door and a mounting piece 6, wherein the rotating shaft 5 is also engraved with Open limit indicating groove 7 and close limit indicating groove 8. The utility model is fixed on the door frame through the mounting piece 6, and the rotating shaft 5 is fixed on the door foot of the cabinet door. The cabinet door is limited by the utility model. When the cabinet door is opened, the rotating shaft 5 of the utility model will follow the door The opening and stretching, but when the opening limit is reached, the door will be stuck in the opening limit indicating groove 7, which can prevent the cabinet door from automatically closing due to its own gravity or other external forces.

Claims (2)

1, a kind of cabinet door limiting device of intelligent medium voltage switchgear equipment is characterized in that: it is a kind of device of the rod-pulling type that contracts, and is made up of spiral compression spring (4), the stretchable rotation axis (5) and the installation sheet (6) that are connected on the door.

2, the cabinet door limiting device of intelligent medium voltage switchgear equipment according to claim 1 is characterized in that: also be carved with out spacing indication groove and close spacing indication groove on stretchable rotation axis (5).
