High-altitude high-voltage isolation switch electric operating mechanism box

Abstract

The invention relates to a high-altitude high-voltage isolation switch electric operating mechanism box, and the box comprises a box body, a top cover, an air-bag type top surface sealing strip, a double-layer door, an outer door frame, an outer door, an inner door frame, an inner door, and an automatic door closer hinge. The top of the box body is connected with the top cover through a fastening part, and at least one side of the periphery of the box body is provided with the double-layer door. The double-layer door comprises the outer door frame, the inner door frame, the outer door and the inner door. The outer door frame is disposed on the box body, and is connected with the box body through a hinge. The outer door achieves the sealing fit with the outer door frame. The inner door frame is disposed in the outer door frame, and the inner door is connected with the outer door frame through the automatic door closer hinge. The inner door achieves the sealing fit with the inner door frame. The box is simple in structure, is good in sealing effect, is high in reliability, is resistant to a low-temperature environment, is convenient to operate and maintain, and is also convenient for popularization and application.

Description

technical field [0001] The invention relates to an electric operating mechanism box for an isolating switch, in particular to an electric operating mechanism box for a high-altitude high-voltage isolating switch used in an open-type (AIS) intelligent substation in a high-altitude area. Background technique [0002] With the rapid development of the power system, the requirements for the safety and reliability of the power grid, the protection level of electrical equipment and the ability to adapt to extreme environments are constantly increasing. At present, the sealing ability of the electric operating mechanism box of the conventional high-voltage isolating switch is not strong, especially when it is used in the high-altitude area of ​​Northwest China, wind and sand can easily enter the electrical components in the mechanism box, resulting in poor contact of the electrical components or contact jamming of the operating components when the electrical components are energized...

AI Technical Summary

Problems solved by technology

In high-altitude areas, the temperature is low all year round, and the grease on the transmission part of the outdoor high-voltage isolating switch, the inside of the bearing seat and the reducer of the operating mechanism is easy to solidify. If the ambient temperature is lower than the freezing point of the grease, the outdoor high-voltage isolating switch will be stuck stagnant
