GIS Tank Type Surge Arrestors

설명

Introduction:
The Tank Type GIS Surge Arrester is a state-of-the-art protective device meticulously engineered to shield sulfur hexafluoride gas-insulated substation combined electrical equipment (GIS) from potential damages caused by lightning and operational over-voltages. This AC gapless, gas-insulated, metal-enclosed metal oxide arrester is a testament to our company’s commitment to quality and innovation, with over six years of impeccable operational track record.

Advancements:
In line with the evolving needs of GIS, our company has pioneered the development of large-capacity high-gradient metal oxide resistors to cater to the miniaturization trend in the market. The unique structural design ensures the resistor remains intact during bumpy transits or heavy vibrations, eliminating the risk of partial discharges due to loosening.

Key Components:

1. Zinc Oxide Valve Piece: The primary component that facilitates surge protection.
2. Pressure Equalizing Cover: Ensures uniform distribution of voltage across the arrester.
3. Casing: A metal enclosure that houses the main components of the arrester.
4. Monitor for Lightning Arrester: Facilitates regular checks and monitoring of the arrester’s performance.
5. Basin Insulator: Ensures that the arrester remains insulated from the ground.
6. Electrical Connector: Links the arrester to the electrical circuit of the enclosed device.

Operational Mechanism:
The zinc oxide valve, which is the heart of the arrester, is securely encased within a grounded metal housing. One end of this valve connects to the ground via the arrester’s monitor, while the opposite end forms an electrical connection with the circuitry of the enclosed appliance. For enhanced insulation and performance, the casing is filled with SF6 gas and maintained at a pressure ranging between 0.4 MPa to 0.50 MPa.

Benefits:

• Durability: Withstands strong vibrations and transportation challenges without loosening the resistive piece.
• Safety: Negates the risk of partial discharges, ensuring the uninterrupted functioning of the GIS.
• Flexibility: Can be installed in various forms including dressing, paperback, or flip-chip, as per user requirements.

Recommendations for Users:
For optimal performance and longevity, users are urged to:

1. Adhere to correct installation and testing standards.
2. Schedule regular observations and monitoring to ensure the arrester’s efficiency.
3. Refer to the arrester’s specification, crafted based on relevant standards and long-standing operational experiences, for best practices.

Conclusion:
The Tank Type GIS Surge Arrester is a hallmark of technological advancement and reliability, promising unparalleled protection for your GIS equipment. Trust in its design and capabilities to ensure your systems’ safe and efficient operation.
