Abstract

The invention relates to a 110 kV double-winding vehicle-loaded transformer lead structure. The 110 kV double-winding vehicle-loaded transformer lead structure comprises a high-voltage lead structureand a low-voltage lead structure, wherein the high-voltage lead structure comprises A-phase, B-phase and C-phase high-voltage phase lines; ends of A-phase and B-phase high-voltage phase lines are discharged in the axial direction; the lines are horizontally distributed along an iron core upper clamping piece and are lead to the end, which is close to a C phase, of a fuel tank; the end of the C-phase high-voltage phase line is discharged in a radial direction on a short axis side of the fuel tank; the A-phase, B-phase and C-phase high-voltage phase lines are fixed and guided to the position ofa lower heightening seat on the short axis side of the fuel tank; and after being fixedly clamped in the heightening seat, the A-phase, B-phase and C-phase high-voltage phase lines are connected witha high-voltage sleeve. On the premise of meeting safe and stable running of a transformer, the size of the transformer is greatly reduced, the space of the fuel tank is utilized fully, the volume of the fuel tank is greatly reduced, the using amount of transformer oil and steel is reduced, the transportation size of the transformer is reduced, the economy of a 110 kilovolt double-winding vehicle-mounted transformer is improved remarkably, and transportation flexibility is also improved.

Description

technical field [0001] The invention relates to the technical field of transformer lead wire structure, in particular to a 110kV double-winding vehicle-mounted transformer lead wire structure. Background technique [0002] With the increasing demand for small and medium-sized transformer products and the increasingly fierce market competition, all manufacturers are striving to improve product performance and reduce manufacturing costs in order to obtain greater profit margins. Power transformers designed by traditional methods are large in size, high in cost, and waste of raw materials are no longer suitable for today's development trend. Vehicle-mounted transformers with small size, light weight, and variable voltage transportation are imperative. [0003] As we all know, the miniaturization of vehicle-mounted transformers is mainly restricted by the transportation size of the transformer and the design of its main and longitudinal insulation structures. Therefore, a reaso...
