| Item | Unit | Parameter |
| Rated voltage | kV | The rated voltage of the capacitor is selected according to the technical protocol requirements of the series package |
| Rated frequency | Hz | 50, 60 |
| Rated capacity | kvar | The rated capacity of the capacitor is selected according to the technical agreement requirements of the series package |
| Loss Angle tangent value(tanδ) | ≤0.0003 | |
| Phase | Single | |
| Insulation level | kV | 42/75, 50/125 |
| Discharge resistance | The capacitor is equipped with discharge resistance, and after disconnecting from the grid, the voltage on the terminal can be reduced to less than 75V within 10 minutes | |
| Capacitance deviation | -3%~+5% | |
| Protection method | Inner fuse or No fuse |
1. Bushing: cold-pressed, anti-pollution type bushing, creepage distance is not less than 31mm/kV.
2. Mature internal fuse technology.
2.1 After the test, the internal fuse can isolate the faulty component within a voltage of 0.5√2UN ~ 2.6√2UN and a time of 0.2ms, and the energy released at the fault point is not more than 0.3kJ, and the remaining intact components are not affected.
2.2 Advanced hidden internal fuse structure, using oil gap arc extinguishing, reduce the possibility of capacitor case bursting.
2.3 Internal fuse protection and relay protection have perfect coordination standards to ensure the safe and reliable operation of the entire device.
3. Liquid medium: 100% benzyl toluene (M/DBT) is used, which has excellent low temperature performance and partial discharge performance.
4. The main insulation adopts composite insulation structure, which ensures excellent electrical performance and has certain mechanical strength, ensuring that the ground insulation of the capacitor complete set is 100% reliable without protection.
5. Good sealing performance: annual leakage rate is less than 0.1%, through automatic argon arc welding, vacuum leakage test, hot aging and other measures to ensure the sealing performance of the capacitor.
6. Partial discharge level: the extinguishing voltage is not less than 1.5Un, and each capacitor is tested for partial discharge during factory test.
1. Rated voltage; 2. Rated capacity; 3. Rated frequency; 4. Standards,
5. Service conditions (altitude, temperature, indoor or outdoor, humidity, etc.), 6. Other special requirements.
