Product Description

Product Description
Used for 6-35kV systems, in cable powered systems, the grounding capacitor current is relatively high. When the current exceeds the specified value, there is a possibility of arc grounding overvoltage. The purpose of using a resistor grounding method for the neutral point is to inject resistive current into the fault point, with the resistive component current being 1.05 to 1.1 times the capacitive component current. It is possible to limit the fault current moderately, improve the sensitivity of relay protection, and limit the fault point to only local minor damage. The transient overvoltage can be limited to 2.6 times the normal relative neutral point voltage to prevent arc overvoltage from damaging the main equipment. At the same time, it has a significant effect on the ferromagnetic resonance overvoltage.
The resistors produced by our company are made of stainless steel or stainless steel electric heating alloy materials, which have the characteristics of high conductivity, high temperature coefficient, corrosion resistance, high temperature resistance, strong oxidation resistance, high tensile strength, and stable resistance value. The product operates safely and reliably.
Product Parameters
Introduce:1. Resistance stabilization:The temperature coefficient of resistance is 2.17 × 10-5 Ω ºC(The temperature coefficient of resistance 315 ºC 0.000225/C,426 ºC 0.000249/C,537 ºC 0.000283/C,648 ºC 0.000313/C),ensuring the sensitivity of protection.
2. It can maintain good antioxidant performance at a high temperature of 1000 ºC and is suitable for environments with severe pollution.
3. Good toughness at high temperatures, does not deteriorate, is not easy to break, and has a long service life (promised 20 years).
4. High tensile strength, able to effectively resist the action of electric force.
5. Melting point up to 1500 ºC, short-term allowable temperature rise of 760 ºC, continuous allowable temperature rise of 385 ºC.
6. Reasonable heat dissipation structure, the resistor element adopts a grid structure, with the best cooling airflow channel, avoiding local high temperature points and easily burned points.
7. Product serialization: Applicable voltage: 110V~66KV; Allow flow: 5A to 5000A; Nominal resistance: 0.1 Ω~1500 Ω; Allowable flow time: 10S, 30S, 60S, 2H continuous operation
8. Modular resistor components. It can be combined in series and parallel to meet the needs of different currents, voltages, and resistance values
