Power System Lightning Arresters (Surge Protection)
In power system lightning protection, surge protectors (SPDs) serve as the primary defense against lightning surges and switching overvoltages. High-voltage doorknob capacitors, featuring a unique ceramic dielectric and epoxy resin encapsulation structure, play a critical role in high-frequency filtering and energy buffering.
Technical Performance
When lightning electromagnetic pulses (LEMPs) or switching overvoltages (such as from switch trips) enter the system, doorknob capacitors rapidly absorb high-frequency surge energy to suppress voltage spikes. They work in conjunction with varistors (MOVs) or gas discharge tubes (GDTs) to achieve multi-stage discharge. The low-inductance design ensures nanosecond response times, effectively controlling residual voltage below equipment insulation withstand levels (e.g., ≤1.5kV), preventing damage to downstream precision equipment.
Applications in Renewable Energy
On the DC side of inverters in new energy installations (photovoltaic and wind power), DC SPDs must withstand high temperatures and humidity at 1500VDC. The low loss factor and high insulation resistance characteristics of doorknob capacitors significantly enhance SPD reliability in these demanding environments.
