Product Description

Product Description

(H)GWBEB type outdoor high-voltage isolation switch, renowned as an isolation disconnect switch, is expertly crafted for deployment on high voltage power transmission and distribution lines rated at 10(12, 15, 24)kV. This robust device is engineered to seamlessly open and close single-phase or three-phase circuits without bearing any load but with voltage present, ensuring reliable performance in demanding environments.

Designed specifically for single-phase deployment within three-phase line systems, this switch stands out for its uncomplicated structure, economic viability, and user-friendly operation. It supports a diverse range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. The assembly comprises a base, post insulators, conductive elements, and a mechanical section. Its circuit operation employs a gate knife mechanism, featuring dual conductive blades for each phase, fortified with external compression springs on either side. By adjusting spring height, optimal contact pressure for the gate knife is attained. An insulated hook stick facilitates operational actions of opening and closing, complemented by a self-locking device for security.

Working Environment:

Elevation must not exceed 1000 meters;

Ambient temperature: maximum no higher than +40°C; minimum no lower than -30°C;

Outdoor wind velocity should not exceed 35 meters per second;

The seismic intensity should be no greater than 8 degrees; the installation area should be devoid of frequent severe vibrations.

The installation location must be free from gases, chemical residues, salt mist, dust, dirt, or any other explosive or corrosive mediums that could significantly impair the switch's insulation and conductivity.

Note:

SHOULD THE CONDITIONS FOR NORMAL USE BE EXCEEDED, USERS ARE ENCOURAGED TO DISCUSS ALTERNATIVE OPTIONS WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Eliminate dust and dirt from all parts, and delicately clean the surface of the insulating porcelain bottle for optimal performance.
2. Thoroughly clean the wiring surface of the grounding screw to ensure efficient conductivity.
3. Apply a protective layer of industrial Vaseline at the rotation points and contact areas to ensure smooth operation.
4. Inspect the contact surfaces and adjust the height of the compression spring to meet the specifications outlined in Table II, ensuring proper contact pressure.
5. This switch is specifically designed for hoisting applications and operates in synergy with transformers on the line.
6. For rated currents between 200-400 amp hours, three mounting holes are typically utilized. For 600-1000A configurations, three mounting holes are also employed.

Conduct an annual inspection of these switch components to maintain peak performance:
Remove any accumulated dirt from conductive parts, contact surfaces, and the surface of insulating porcelain bottles to maintain efficiency.

Inspect all components for potential damage, with particular focus on the insulating porcelain bottle for any signs of damage or cracking.

Verify the integrity of the contact surface on the conductive components to ensure reliable connectivity.
