GW4-12(D)W light torque maintenance-free outdoor high-voltage isolating switch is an outdoor high-voltage electrical equipment with a frequency of 50HZ~60HZ, which is used for high-voltage line switching under voltage and no load.

And electrical isolation of the high-voltage busbars, circuit breakers and other electrical equipment to be repaired and the charged high-voltage lines. It can also be used to separate small and small capacitor currents and inductor currents.

According to the grounding switch: no grounding、 single grounding、 double grounding.

By region of use: normal type、 stain-resistant、 high prototype

1. isolation switch action principle
The operating mechanism of the isolating switch is connected to the active stage of the isolating switch through a connecting pipe. The main shaft of the mechanism rotates by 90°, and the insulating pillar that drives the active stage rotates by 90°. The connecting rod in the base drives the other insulating pillar to rotate in the opposite direction to realize the splitting and closing action. The active stage passes through the inter-pole linkage tube to drive the other two. The moving poles rotate to maintain the three-phase synchronous action. The auxiliary switch in the mechanism is connected to the main output shaft of the mechanism, and sends a corresponding split signal when the switch is closed.

2. the grounding switch action principle
The main shaft of the three-phase grounding switch is connected by a horizontal connecting pipe through a joint, and the handle of the operating mechanism is rotated horizontally by 90°, and the horizontal connecting pipe driven by the connecting rod is rotated to realize the grounding switch closing and closing action.

3. manual mechanism action principle
The operating mechanism is connected to the main shaft of the isolating switch and the grounding switch through the connecting pipe. The CS8-6D manual mechanism is equipped with an isolating switch with a grounding knife, and the output shaft is provided with a mechanical interlocking plate to ensure operation according to the prescribed procedure.
