Abstract

The embodiment of the invention provides a 110kV three-phase dry-type transformer, and the 110kV three-phase dry-type transformer comprises three connected single-phase dry-type transformers, whereineach single-phase transformer comprises a wire inlet side high-voltage coil and a wire outlet side high-voltage coil; the wire inlet side high-voltage coil is provided with a wire inlet end and a wireoutlet end, and the wire outlet side high-voltage coil is provided with a wire inlet end and a wire outlet end; the wire outlet end of the wire inlet side high-voltage coil is connected with the wireinlet end of the wire outlet side high-voltage coil, and the wire inlet side high-voltage coil is in series connection with the wire outlet side high-voltage coil. According to the invention, the wire inlet ends are arranged at the middles of the high-voltage coils at all sides, so the lightning impulse voltage resistance of the wire inlet ends of the high-voltage coils at all sides is improved,the lightning impulse voltage resistance of the whole three-phase dry type transformer is further improved, and the requirement for the voltage resistance of insulation of the three-phase dry type transformer under the 110kV voltage level is met.

Description

technical field [0001] The present application relates to the technical field of power transformers, in particular, to a 110kV three-phase dry-type transformer. Background technique [0002] At present, most of the existing three-phase dry-type transformers are used for low voltage levels, such as 35kV. In the case of higher voltage levels (such as 110kV voltage level), the existing three-phase dry-type transformers will have insufficient insulation level and cannot meet 110kV The problem of the voltage withstand capability requirements of the voltage level insulation. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide a 110kV three-phase dry-type transformer, which is used to solve the problem that the existing three-phase dry-type transformer has insufficient insulation level and cannot meet the requirements of the voltage withstand capacity of the transformer insulation in the case of a voltage level of 110kV. . ...
