BTK-126/252 Transformer Neutral Protection Device


BTK-126/252 transformer neutral auxiliary combination mainly includes the following equipmentsneutral disconnector; discharging clearance; zinc-oxide lightning arrester and current transformer for measuring discharging current ect . when transformer neutral point appear light-ning over-voltage, it has protective function when operating over-voltage and transient over-voltage. Lightning arrester undertakes lightning over-voltage protection, when the system occur single phase earthing fault and in the process of single phase close, horizontal stick should not discharge. The characteristic of compound clearance: when lightning over-voltage, lightning arrester operate,clearance doesn’t operate; on the condition of inner over-voltage, lightning arrester doesn’t operate, clearance operate.
