Product Description

Product Description

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

This switch is ingeniously engineered for single-phase usage within three-phase line systems, renowned for its straightforward design, cost-effectiveness, and user-friendly operation. It boasts an impressive range of available rated currents: 200, 400, 600, 800, 1000, and 1250 amps. Comprising a robust base, post insulators, conductive components, and a mechanical section, each switch employs a sophisticated gate knife structure designed for precise circuit control. Each phase's gate knife features two conductive blades, fortified with external compression springs on both sides. By adjusting the height of these springs, the desired contact pressure for the switch's gate knife is flawlessly achieved. Operated via an insulated hook stick, the switch not only ensures efficient opening and closing actions but also incorporates a reliable self-locking device for enhanced safety.

Working Environment:

Elevation: Max altitude not exceeding 1000 meters;

Ambient temperature range: Maximum not above +40°C and minimum not below -30°C;

Outdoor conditions: Wind speeds not surpassing 35 meters per second;

Seismic resilience: Capable of withstanding seismic intensity not exceeding 8 degrees. The installation site should be free from frequent severe vibrations to ensure operational stability.

Environmental purity: The installation site should maintain an atmosphere devoid of harmful gases, chemical deposits, salt mist, dust, dirt, or any other explosive or corrosive mediums that could severely impact the switch's insulation and conductivity.

Note:

WHEN STANDARD OPERATING CONDITIONS ARE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS CUSTOM SOLUTIONS WITH THE COMPANY.

 

Installation, Use and Adjustment

Pre-installation Work

1. Thoroughly cleanse all components by removing dust and dirt, and delicately wipe the surface of the insulating porcelain bottle to ensure optimal performance.
2. Clean the wiring surface of the ground screw to maintain effective connectivity.
3. Apply a protective layer of industrial Vaseline to all rotating parts and contact areas to ensure smooth operation and longevity.
4. Inspect the contact surface and adjust the height of the compression spring to ensure the contact pressure aligns with specifications detailed in Table II.
5. Specifically designed for hoisting applications, this switch is seamlessly used in conjunction with the transformer on the line for enhanced efficiency.
6. The rated current for this switch encompasses 200-400 ampere hours, typically utilizing three mounting holes. For 600-1000A, three mounting holes are similarly employed to ensure stability.

Conduct a meticulous annual inspection of the following switch components:
Diligently remove any dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to ensure superior performance.

Examine all components for damage, with particular focus on the insulating porcelain bottle for any signs of damage or cracks.

Assess the contact surfaces of conductive parts to confirm their optimal condition and performance.
