本係列電流互感器適用於戶肉 , 額定頻率50Hz或60Hz額定電壓35kV及以下的小接地電流係統中供三棺電纜接地保護用, 也可與繼電器配套使用。
安裝時可將互感器分為兩半, 然後合並為一體, 用抱箍抱緊卡住。可以在不停電狀態下進行安裝。
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.
