本系列電流互感器適用于戶肉 , 額定頻率50Hz或60Hz額定電壓35kV及以下的小接地電流系統(tǒng)中供三棺電纜接地保護(hù)用, 也可與繼電器配套使用。
安裝時(shí)可將互感器分為兩半, 然后合并為一體, 用抱箍抱緊卡住??梢栽诓煌k姞顟B(tài)下進(jìn)行安裝。
These series of current transformers are used indoor. They are used for three plases overdriven current protection in the electric not-useful-ground neutral system up to rated freguency 50Hz or 60Hz and rated voltage 35kV. The transformers are fitting with the relay too.
Being installed , at first, make the product dimidiation. Then make it coalition use bolt. Can be loaded at hot-line condition.
