Product Description

Product Description

The (H)GWBEB type outdoor high-voltage isolation switch, which is often referred to as an isolation disconnect switch, is expertly crafted to function 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 while sustaining voltage, but without load, making it essential for efficient power management and reliability.

This switch is specially designed for single-phase operations within three-phase line systems, offering simplicity, affordability, and user-friendly handling. It is available in a range of rated currents: 200, 400, 600, 800, 1000, and 1250 amps. The switch is comprised of a sturdy base, robust post insulators, highly conductive components, and a mechanical section. It employs a precise gate knife mechanism for circuit operation. Each phase's gate knife features dual conductive blades with external compression springs on both sides. The necessary contact pressure for the gate knife is achieved by finely adjusting the spring height. An insulated hook stick facilitates the switch's operational maneuvers, and a self-locking device ensures secure usage.

Working Environment:

This switch is designed to operate efficiently at altitudes not exceeding 1000 meters, ensuring optimal performance and reliability.

It is engineered to function within a broad range of ambient temperatures, with a maximum of +40°C and a minimum of -30°C, accommodating various climatic conditions.

The switch withstands outdoor wind speeds up to 35 meters/second, maintaining its integrity and operational stability.

It is built to endure seismic intensities up to 8 degrees, provided that the installation site does not experience frequent intense vibrations, ensuring durability and safety.

The installation site must be free from gases, chemical deposits, salt mist, dust, dirt, or other explosive or corrosive mediums that could severely impair the switch’s insulation and conductivity, guaranteeing long-lasting performance.

Note:

WHEN THE USAGE CONDITIONS SURPASS THE NORMAL PARAMETERS AS DESCRIBED, USERS ARE ENCOURAGED TO DISCUSS ALTERNATIVE SOLUTIONS WITH THE COMPANY TO ENSURE CONTINUED EFFECTIVENESS.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly remove any dust and dirt from the switch components, and delicately clean the insulating porcelain bottle surfaces to ensure pristine conditions for installation.
2. Carefully scrub the wiring surface of the ground screw to maintain optimal electrical connectivity.
3. Apply a generous layer of industrial Vaseline to the rotating parts and contact areas to facilitate smooth operations and prolong the switch's lifespan.
4. Inspect the contact surfaces and precisely adjust the compression spring heights to meet the standards outlined in Table II, ensuring secure connections and reliable performance.
5. This switch is designed exclusively for hoisting applications, meant to be used in conjunction with transformers along the power line, adding versatility to its functionality.
6. With a rated current between 200-400 ampere hours, the switch typically utilizes three mounting holes, whereas for 600-1000A, the same three mounting holes are used to ensure stability and support.

Conduct an annual examination of the following switch components:
Diligently remove dirt from conductive components, contact surfaces, and insulating porcelain bottles to maintain seamless operation and avoid any disruptions.

Inspect all parts for any potential damage, giving special attention to the insulating porcelain bottles for any cracks or breaks that could compromise safety and functionality.

Examine the conductive components to ensure the contact surfaces maintain their intended quality and efficiency.
