Description

Technical Field

[0002] High-voltage disconnectors are important switchgear in the electrical systems of power plants and substations. They have a great impact on the safe operation of substations and power plants. Therefore, high reliability requirements are placed on their operation, and frequent maintenance is required.

[0003] Since most high-voltage disconnectors are used outdoors at high places, maintenance equipment is often required during maintenance. At present, maintenance personnel are generally transported to the location of the high-voltage disconnector using a maintenance bracket. During maintenance, the components that need to be repaired are disassembled, and the maintenance personnel and components are transported down together using the maintenance bracket. The disassembled components are repaired on a separate maintenance platform. After the maintenance is completed, the components are transported to the location of the high-voltage disconnector and installed. This is not only troublesome to operate, increasing the workload of maintenance personnel, but also relying solely on the extension and retraction of the piston rod of the hydraulic cylinder to achieve the lifting and lowering of the maintenance bracket. During the lifting and lowering process, the maintenance bracket may be offset, the lifting and lowering are not stable enough, the safety is low, and the maintenance platform has a poor fixing effect on the components, which is not convenient for maintenance personnel to perform maintenance operations on the components, and the applicability is not strong. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Utility Model Content
