Self-healing capacitor
-
- Commodity name: Self-healing capacitor
- Commodity ID: 1362032596631572480
- 类型: Electrical energy remediation
- 品牌: Capni
Brand: Zhiyuan New Energy Description: Self-healing low-voltage shunt capacitors are primarily used to improve the power factor of power systems operating at industrial frequency, enhance the quality of power supply in the grid, and increase the reliability of electricity consumption. They feature stable and reliable operation, low temperature rise, high cost performance, and can meet the demand for large-capacity capacitors in single-unit applications.

Self-healing: Excellent self-healing capability—once punctured, the insulation performance can quickly and automatically recover.
Permissible deviation: no more than -2% to +3% of the rated value.
Low Loss: The tangent of the loss angle (tan δ) is no greater than 0.001 (@ rated power frequency voltage, 20℃).
Overvoltage capability: Long-term operation at 1.1 Un.
Overcurrent capability: Long-term operation at 1.3 In.
Withstand Voltage: Apply 2.15Un between poles for 2 seconds without breakdown;
Apply 3.5 kV AC to the extreme shell for 10 seconds without breakdown.
Protection mechanism: Equipped with a built-in pressure protection device.
Implementation standards: GB/T12747-2017 “Self-healing Low-Voltage Shunt Capacitors” and IEC60831.
