Product Description

Product Description

        For power systems with different voltage levels, the neutral point grounding mode is different, according to China's national conditions, China's 6~66KV distribution system mainly uses small current grounding operation mode. In order to effectively prevent the arc grounding of the system, eliminate the grounding fault, and improve the quality of power supply, according to the new regulations of the national design code for overvoltage protection, when the capacitor current of the power grid exceeds 10A, the arc suppression coil device should be installed.
        Our company produces the LY-PTH series of turn type arc suppression coil device, the complete set of devices adopts standard industrial computer system, bus structure, multi-layer circuit board design, full color LCD screen, full Chinese character display. It has the characteristics of stable and reliable operation, intuitive display, strong anti-interference ability, etc. At the same time, the system has perfect parameter setting and information query function. The system overcomes the limitation of small adjusting range of previous arc-suppressing coil devices and can be adjusted comprehensively.

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
