Description

The air break switch is an essential component for high voltage outdoor electrical systems, specifically designed for AC 50Hz applications. The GW4 outdoor disconnecting switch is available in rated voltage grades of 40.5kV, 72.5kV, and 126kV, making it suitable for various high-voltage environments. This switch is engineered to facilitate the reliable switching on and off of high circuits under load, providing electric isolation for appliances such as circuit breakers and maintenance of high voltage bus systems. Furthermore, it is capable of handling small capacitive or inductive currents, ensuring versatility in its application.

The structure of the discharging switch consists of a base, insulation post, conductive parts, and an operation mechanism. Each pole features two posts, with conductive switch blades assembled at the top. The contact points are strategically positioned between the two posts, allowing for efficient operation. The design incorporates bearing housings at the lower end of the posts, enabling the switch blade to rotate 90 degrees horizontally, thus facilitating reliable disconnection or connection.

This disconnecting switch is primarily a single pole type but can be configured as a three-pole type using linking rods. It can be integrated with either the Cs11 or Cs17 type manual operation mechanisms, with the CS17 model specifically designed for disconnecting switches with earthing equipment. An electric mechanism can also be integrated based on user requirements. Overall, the disconnecting switch boasts a reasonable structure, flexible operation, convenient installation, and a large gap between switch blades, allowing for single or three-pole configurations and adaptable earth control options.
