1. Narrative
Three phase combined lightning arrester, also known as overvoltage protector, is a new type of protector developed to address the weak protection level of traditional lightning arresters against phase to phase overvoltage. The product adopts a four star structure, which can provide protection for both phase to ground overvoltage and phase to phase overvoltage. It provides excellent protection against the overcurrent and reignition overvoltage caused by the disconnection of vacuum circuit breakers. Mainly used to protect electrical equipment such as transformers, new energy switchgear, busbars, motors, etc., it can provide good protection against atmospheric overvoltage, cut-off overvoltage caused by vacuum circuit breaker breaking, and various operating overvoltages.
