Power System Lightning Arresters (Surge Protection)
Technical Cornerstone: The Core Role of High-Voltage Doorknob Capacitors in Lightning Arresters
In power system lightning protection, surge protectors (SPDs) are the first line of defense against lightning surges and switching overvoltages. High-voltage doorknob capacitors, with their unique ceramic dielectric and epoxy resin encapsulation structure, play a key role in high-frequency filtering and energy buffering. When lightning electromagnetic pulses (LEMPs) or switching overvoltages (such as a switch trip) intrude into the system, doorknob capacitors quickly absorb high-frequency surge energy, suppressing voltage spikes. They then work with varistors (MOVs) or gas discharge tubes (GDTs) to achieve multi-stage discharge. Their low-inductance design ensures nanosecond response speed, effectively controlling residual voltage below the equipment's insulation withstand level (e.g., ≤1.5kV), preventing damage to downstream precision equipment due to overvoltage. For example, on the DC side of the inverter in new energy sites (photovoltaic and wind power), the DC SPD needs to withstand high temperature and high humidity at 1500VDC. The low loss factor and high insulation resistance characteristics of the door handle capacitor can significantly improve the reliability of the SPD in harsh environments.
