Disconnect Switch

Disconnect Switch

Disconnect switches generally refer to high voltage disconnect switches with 1kv or above rated voltage. In the circuit, disconnect switches have the function of isolation. They are the most commonly used switches among all high voltage switching apparatus. Its operating principle and structure are simpler. However, as they have a large usage amount, a high operational reliability is required, which has great influence on the design, building and safe operation of electric power substations and electric power plants. The disconnecting link has no arc extinction ability, so it only can seperate and close circuits when there is no load current.
According to the method of installation, disconnect switches can be divided into indoor disconnect switches and outdoor disconnect switches. Outdoor disconnect switches can work in bad environment and is resistant to the corrosion of wind, rain, snow, dew, ice, heavy frost and dirty things. High voltage disconnect switches are suitable for working outdoors and are mainly applied to rural power grids and rural-urban fringe zone with a large market. The low voltage disconnect switches are suitable for low voltage end power distribution system in home, building and other places.
