Purpose
♦It is outdoor, single phase and oil immersed hair-pin type current transformer,
which
is used for metering and relay protection of 33/36kV, 50 or 60Hz systerm.
Standards
♦ IEC61869-1: Instrument transformers – Part 1 General requirements
♦ IEC61869-2 Instrument transformers - Part 2 Additional requirements for current
transformers
Service condition
♦ Ambient temperature:-40~+40℃
♦ Altitude: LB-33(W1,W2,W3) less than 1000m
♦ LB-33GY(W1,W2,W3) less than 3500m
Overview:
♦ It is outdoor, single phase and oil immersed top-heaad type current transformer,
which is used for metering and relay protection of 66/69/72.5kV, 50 or 60Hz systerm.
It is oil/paper insulation structure, the primary is wound from voltage cable paper,
and is placed sevral capacitor screen of voltage division in the primary insulation,
which can improve electric fied distributing and increase the consumption of
insulation material. It will be immersed with transformer oil after desicating under
cacuum. It has advantages of stable and reliable performance of insulation, rich
successful experience, a long life time.
Service condition
♦ Ambient temperature is -40~+40℃.
♦Altitude: ≤2000m(If above 2000m,the producer will be customized according to
user's request)
♦ Environment pollution level: Ⅱ,Ⅲ,IV
