Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, also renowned as an isolation disconnect switch, is meticulously engineered for deployment on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is adept at opening and closing single-phase or three-phase circuits, without load yet under the presence of voltage. This switch stands as an indispensable component in modern power management.

This switch is crafted for single-phase use within three-phase line systems, marked by its straightforward design, economic viability, and user-friendly operation. It is available in an array of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. The switch comprises a robust base, post insulators, conductive elements, and a mechanical section. The innovative gate knife structure ensures efficient circuit opening and closing. Each phase's gate knife includes two conductive blades, augmented by external compression springs on either side. The spring height can be adjusted to achieve the desired contact pressure for optimal performance. An insulated hook stick facilitates the switch's opening and closing, while a self-locking device enhances operational security.

Working Environment:

Altitude constraints: not exceeding 1000 meters;

Ambient temperature: maximum of +40°C; minimum of -30°C;

Outdoor conditions: wind speed not exceeding 35 meters/second;

Seismic resilience: capable of withstanding seismic intensity up to 8 degrees; installation sites should remain free from frequent severe vibrations.

The installation site must remain free of gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could significantly impair the switch's insulation and conductive capabilities.

Note:

IN CASE OF CONDITIONS EXCEEDING THE STANDARD USAGE REQUIREMENTS, CUSTOMERS ARE ENCOURAGED TO CONSULT AND NEGOTIATE WITH THE COMPANY.

 

Installation, Use and Adjustment

Pre-installation work

1. Ensure all parts are free from dust and dirt by thoroughly cleaning them, with particular attention to the surface of the insulating porcelain bottle.
2. Meticulously scrub the wiring surface of the ground screw to ensure optimal conductivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to enhance durability and performance.
4. Inspect the contact surface and adjust the compression spring height to ensure the contact pressure aligns with the specifications outlined in Table II.
5. This switch is exclusively designed for hoisting use, working harmoniously with the transformer on the line to ensure reliable power distribution.
6. For switches rated at 200-400 ampere hours, typically three mounting holes are utilized. For those rated at 600-1000A, three mounting holes are consistently used to ensure stability and performance.

Annual maintenance checklist: Regularly inspect the following components:
Thoroughly clean dirt from the conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain optimal performance.

Conduct a detailed examination of all parts for any signs of damage, with special emphasis on identifying damage or cracks in the insulating porcelain bottle.

Assess whether the contact surface of the conductive parts is intact and functioning efficiently.
