Wuhan Switchgear

Main Features of Wuhan Switchgear:

Novel Structure

The switchgear's trolley is connected to the rotating guide rail via a pusher. Closing the rotating guide rail automatically pushes the trolley from the test position to the working position; opening the rotating guide rail automatically pulls the trolley from the working position to the test position. Pressing down the connecting rod of the pusher allows the trolley to be pulled along the opened rotating guide rail from the test position to the maintenance position outside the switchgear. This structure features simple and effortless pushing and pulling of the trolley; accurate positioning of the trolley with strong interchangeability; and unaffected trolley movement by floor height.

High Reliability of Main Switch Operation

Combining mining characteristics, the ZK1 vacuum circuit breaker, optimized by our company's technical personnel, features a simple structure, fewer components, and high operational reliability.

In frequent operation scenarios, our company's general manager's invention, the BC switch—award-winning product at the Paris Invention Exhibition—can replace traditional vacuum circuit breakers. The BC switch integrates the main functions of a circuit breaker and a contactor. During normal operation, it operates like a contactor, featuring a simple operating mechanism, high reliability, frequent operation capability, and long mechanical and electrical life. Upon encountering short-circuit current, the BC switch automatically switches to circuit breaker mode to interrupt the short-circuit current.

Small Footprint and Light Weight

The standard single-layer trolley-type high-voltage vacuum switchgear has external dimensions of width*depth*height as 800mm*1150mm*1700mm. Its small footprint helps save infrastructure investment and facilitates underground transportation.

Comprehensive Protection Functions

The switchgear can be configured for various protection functions according to different uses, including short-circuit, overcurrent, leakage, high-voltage cable core insulation monitoring, undervoltage, and operational overvoltage protection. Protection devices can be traditional electromechanical relays or microcomputer-based comprehensive protection devices, as well as comprehensive automation protection devices with remote control, telemetry, and telemetry functions.

High Enclosure Protection Level

The switchgear's enclosure protection level is IP54, higher than that of ordinary switchgear.
