Switch layout structure of convertible current voltage transformer

Abstract

The invention relates to a switch layout structure of convertible current voltage transformer, the structure comprises a self body oil tank provided for a receiver self body, and three switch oil tanks provided respectively for receiving three single phase switches, the three single phase switches provide outside convex openings on one tank wall side, the three switch oil tank outside convex openings are detachable and joined with self body oil tank outside side wall, the receiver self body voltage regulator and the wire guide together with the single phase switch voltage regulator and the wire guide adopts detachable link structure and one-to-one respective links inside and outside convex openings. The structure effectively resolves the issue that the weight and width of convertible current voltage transformer are restricted by conditions of rail route transport, the structure possesses reliable insulation ability, places simple structure and configuration, costs comparatively low and possesses compact overall structure, reinforces oil tank strength, saves oil consumption for voltage transformer.

Description

[0001] Field [0002] The invention relates to a transformer layout structure, in particular to a converter transformer switch layout structure. Background technique [0003] The converter transformer is an important equipment in the DC transmission system. It is at the core position between the AC grid side and the converter valve. The reliability of the converter transformer plays a very important role in the safe and stable operation of the entire DC transmission system. At present, the transportation methods of converter transformers are limited to road transportation and railway transportation. With the increase of transmission power and voltage level of DC transmission projects, the weight of converter transformers and the width and length of fuel tanks also increase. The weight and width of the conventional structure converter transformer connected to the switch arrangement and one end of the body inside the fuel tank cannot meet the requirements of railway transportati...
