Stainless Steel Neutral Point Grounding Resistor for Generator
Product Introduction
In HVDC or UHVDC,the neutral point grounding of convertor station's AC switch connecting transformer(side of value)is used with resistor to prevent damage to high voltage cable and other electrical equipment due to sudden short circuit,intermittent arc grounding overvolatge and etc,improve operation reliability and safety level of electrical system.
Main Features:
1. Quick thermal dissipation: Plate shaped structure with large area,dissipation is quick;
2. Low noise: The adjacent resistant wire inside the disc may be made in the reverse direction of current to offset the magnetic field,the operation niose is little;
3. Large thermal capacity: The unique processing technology brings about increased effective energy of the resistor discs,the rated power of a single disc can reach 2000W;
4. High insulation performance: Special insulation material is used to separate the resistor discs to ensure the excellent insulation performance;
5. Sound and artistic: Special resistor disc edge clipping mode ensures the soundness of discs,free from vibration and artistic;
6. Durable: Resistor disc is made of alloy materials thus being durable and never broken.
