GN30-12M series rotary indoor high voltage disconnect switch is a new type of touch rotating knife type disconnect switch,
the main structure in three phase chassis of the upper and lower two plat,
fixed two set of insulato rand contact, by rotatirlg contactor,realize the divide and combine the switch.
The main function of an indoor high voltage isolating switch is to provide a visible and reliable method of isolating electrical equipment or parts of a circuit from the power supply. It safely maintains, repairs or inspects electrical systems without the risk of electric shock or equipment damage.
Indoor High Voltage Disconnect Switch Operation: Disconnect switches are usually manually operated using a handle or lever. When a switch is in the closed position, it allows current to flow through a circuit or device. When the switch is open or in the off position, it breaks the electrical connection, isolating the circuit or device from the power source.
Application: Indoor high voltage disconnectors are commonly used in distribution systems, substations, switchgear and other high voltage applications. They provide a means of isolating transformers, circuit breakers, busbars, and other equipment for maintenance or repair work.
