Description

Technical Field

[0001] The utility model relates to the technical field of isolating switches, in particular to a safe high and low voltage isolating switch. Background Art

[0002] Disconnectors generally refer to high-voltage disconnectors, that is, disconnectors with a rated voltage of 1kV or above, usually referred to as disconnectors. They are the most commonly used type of high-voltage switchgear. Their working principle and structure are relatively simple, but due to their large usage and high requirements for working reliability, they have a great impact on the design, establishment and safe operation of substations and power plants. Existing disconnectors are usually directly exposed to the power plant environment, and the dust in the plant area is in direct contact with the switch, affecting the service life of the dust. At the same time, the switch may also be attached with water mist, posing a threat to the life of the user. Utility Model Content
