Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, known as an isolation disconnect switch, is expertly engineered for seamless operation on 10(12, 15, 24)kV high voltage power transmission and distribution lines. It is meticulously crafted to facilitate the opening and closing of single-phase or three-phase circuits efficiently, without load, but with voltage present.

Designed for single-phase applications within three-phase line systems, this switch is renowned for its straightforward architecture, cost-efficiency, and user-friendly operation. It is available in rated currents of 200, 400, 600, 800, 1000, and 1250 amps, ensuring versatility for various needs. Comprising a base, post insulators, conductive components, and a mechanical section, it employs a gate knife structure for circuit engagement and disengagement. Each phase's gate knife features dual conductive blades, complemented by external compression springs on both sides to achieve optimal contact pressure. Spring height adjustments are made to ensure precise pressure. The switch is operated effortlessly with an insulated hook stick, and it includes a reliable self-locking device for enhanced security.

Working Environment:

Altitude not exceeding 1000 meters;

Ambient temperature: maximum not above +40°C; minimum not below -30°C;

Outdoor wind speed not exceeding 35 meters per second;

Seismic intensity not exceeding 8 degrees; the installation site should be free from frequent severe vibrations.

The installation site should be devoid of gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive substances that could significantly impact the switch's insulation and conductivity.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY.

 

Installation, Use, and Adjustment

Pre-installation work

1. Thoroughly remove dust and dirt from all components, meticulously wiping the surface of the insulating porcelain bottle to ensure cleanliness.
2. Scrub the wiring surface of the ground screw to maintain optimal connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to reduce friction and enhance durability.
4. Inspect the contact surface meticulously and adjust the compression spring height to ensure the contact pressure aligns precisely with the standards detailed in Table II.
5. This switch is specifically tailored for hoisting use and is designed to operate seamlessly in tandem with transformers on the line.
6. The switch caters to rated currents of 200-400 amperes, typically requiring only three mounting holes. For 600-1000A, three mounting holes are used to ensure stability and safety.

Perform a comprehensive annual inspection of the following switch components:
Diligently remove dirt and residues from conductive parts, contact surfaces, and the insulating porcelain bottles to maintain optimal performance.

Conduct a thorough examination of all components for potential damage, with particular focus on identifying any damage or cracks in the insulating porcelain bottle.

Verify the integrity of the conductive part's contact surfaces to ensure they are in excellent condition.
