Structure Feature of Oil-Immersed Type Current Transformer

It is oil/paper insulation system, the primary 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 desiccation under vacuum. It has advantages of stable and reliable performance of insulation, rich successful experience, a long life time and convenient maintenance. 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.
The current ratio can be changed easily by change the connection method of connecting plate on oil conservator to series or parallel connection.
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 and refilling.
The primary terminal and secondary terminal of earth screen in the terminal box.
The oil conservator and base etc use DACRAL (Zinc/Chromate coatings) for resistance to corrosion, which gives a high degree of corrosion resistance.
The primary over-voltage protection device and secondary open circuit over-voltage protection device can be provided according to the requirements of user.
