Abstract

The invention provides a 10KV oil-immersed transformer. The 10KV oil-immersed transformer comprises an oil tank, an iron core, windings, insulating sleeves and an oil temperature measuring device. Transformer oil for cooling and insulating the windings is arranged in the oil tank. A high-permeability crystal orientation cold rolling silicon sheet is adopted in the iron core. The iron core is a core-type iron core. The windings are each of a multilayer cylinder type structure. The oil tank is provided with a conservator for storing and replenishing oil for the oil tank. The conservator is a capsule type conservator. The oil temperature measuring device is arranged at the top of the oil tank. The oil tank is provided with a pressure relief valve. The side wall of the oil tank is a corrugated wall. Dust is sprayed to the surface of the oil tank, and a film is painted to the surface of the oil tank so that an outer protective layer can be formed. The 10KV oil-immersed transformer is low in cost, easy to maintain, good in heat dissipation, high in overload capacity and wide in adaptive environment. It is guaranteed that oil does not need to be replaced when the oil-immersed transformer normally runs, the maintenance cost of the transformer is greatly reduced, and meanwhile the service life of the transformer is prolonged.

Description

Technical field [0001] The invention relates to a 10KV oil-immersed transformer. Background technique [0002] transformer It is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core or magnetic core. The main functions of the transformer are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, etc. According to the purpose, it can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc. Transformer installation insulation cooling is classified into oil-immersed transformers and dry-type transformers. The oil-immersed transformer is to strengthen the insulation and cooling conditions. The core and windings of the transfor...
