Smart Grid Lightning Protection Applications
With the advancement of smart grid technology, lightning protection systems are evolving from passive protection to active monitoring and predictive maintenance solutions. In smart SPDs integrated with NB-IoT technology, our high-voltage doorknob capacitors serve dual functions:
- Traditional filtering capabilities for surge protection
- Providing stable voltage sampling references for online monitoring circuits
For instance, in Dekai Technology's smart capacitor cabinet SPDs, these capacitors enable real-time data transmission of leakage current and temperature measurements via RS485 communication. The capacitors' exceptional performance characteristics include:
- Low voltage coefficient
- Linear temperature characteristics (±0.5% value change from -40°C to +85°C)
These features ensure precise monitoring data accuracy. In UHV substations, our custom doorknob capacitors (voltage ≥ 300kV) form RC absorption circuits with ZnO varistors, achieving:
- Over 60% reduction in switching overvoltage steepness
- Effective protection for GIS (gas insulated switchgear) against VFTO (fast transient overvoltage)
