33kV Oil immersed Dead Tank Current Transformer
Scope
◆It is outdoor, single phase and oil immersed hair-pin type current transformer, which is used for metering and relay protection of 20~35kV, 50 or 60Hz system.
Standards
◆IEC 61869-1; IEC 61869-2
Service conditions
◆Ambient temperature: -40~+45℃
◆Altitude: ≤1000m (If above 1000m,the product will be customized according to user’s request)
◆Pollution level: II, III, IV
Design features
◆It is oil/paper insulation structure. The main insulation is wound from high voltage cable paper, and is placed several capacitor screen of voltage division in the primary insulation, which can improve electric field distributing and decrease the consumption of insulation material. It will be immersed with transformer oil after desiccating under vacuum. It has advantages of stable and reliable performance of insulation, rich successful experience, a long life time.
◆Perfect fluidity performance of transformer oil is good for heat dissipation, it also has self recover ability for the failure of partial discharge caused by air bubble and dust.
◆Hermetically sealed stainless steel metallic bellows is installed on the top, which protect the transformer oil from moisture and extend the life time, also there is a oil level gauge on the bellows for observing the changing of oil volume.
◆There is a multi function oil drain valve on the base, which make it more convenient for sampling, draining .
◆The current ratio can be changed easily by change the connection method of connecting plate on oil conservator to series or parallel connection.
◆All adopted insulation parts are environmental protection material.
◆Secondary terminal board is made of epoxy casting, the seal performance is more reliable.
◆The base uses spray painting or hot galvanizing, which gives a high degree of corrosion resistance.
◆Fasteners and nameplate are stainless steel.
