Movable door mechanism of high voltage switch cabinet

Abstract

The invention discloses a movable door mechanism of a high voltage switch cabinet, the movable door mechanism comprises a movable door and is characterized in that the movable door is a roller shutter door capable of being movably and oppositely opened up and down, and the roller shutter door comprises an upper roller shutter door panel and a lower roller shutter door panel; guide rails used for guaranteeing the synchronous movement and accuracy of the two sides are installed on the two sides of the roller shutter door; the guide rails have curve shapes slightly protruding outwards; the movable door mechanism further comprises a driving mechanism used for driving the roller shutter door to open and close; the driving mechanism comprises a soft steel wire, dead pulleys and a slide block; one end of the soft steel wire is fixedly connected with the end part of the middle position of the roller shutter door and is respectively led out from the end parts of the guide rails along the guide rails, and the soft steel wire is fixedly connected with the slide block after rounding the other ends of a plurality of dead pulleys. The movable door mechanism of high voltage switch cabinet provided by the invention is safe and reliable, flexible in operation and convenient in use.

Description

technical field [0001] The invention relates to a valve mechanism of a high-voltage switch cabinet. Background technique [0002] At present, the requirements for the technical performance, operation and use, maintenance and other aspects of the removable high-voltage switchgear in the power system are getting higher and higher, especially the requirements for safety. As the cover of the charged body of the high-voltage switchgear, the accuracy and reliability of the opening and closing of the valve are particularly important. [0003] In high-voltage switchgear, in order to prevent the contacts from being electrified during maintenance and endanger the personal safety of the maintenance personnel, a valve mechanism is generally installed in the switch cabinet. When the handcart is pushed into the switch cabinet to work, the valve is opened; when the handcart is pulled out for maintenance, the valve is closed. , shield live contacts, thereby protecting the personal safety o...

AI Technical Summary

Problems solved by technology

Since the main components of the cabinet are vertically arranged, in order to avoid the valve and other components, especially the busbar, causing failures caused by mutual interference, generally only increase the cabinet space, the valve transmission mechanism is often jammed, and the left and right movements are inconsistent, causing the valve to tilt, so Causes a series of problems such as unsafe maintenance switchgear, loose cabinet structure, unreliable operation, etc.
