Abstract

A solar inversion three-dimensional rolling iron core dry type transformer lead structure is characterized by comprising an A-phase coil, a B-phase coil and a C-phase coil which are wound on an iron core leg, each phase coil consists of a primary coil and a second coil; the head end (22) of the A-phase primary coil is connected with the tail end (27) of the B-phase primary coil, the head end (23) of the B-phase primary coil is connected with the tail end (25) of the A-phase high-tension coil, the head end (24) of a C-phase high-tension coil is connected with the tail end (26) of a B-phase high-tension coil, and the head end (22) of the A-phase primary coil, the head end (23) of the B-phase primary coil and the head end (24) of the C-phase primary coil are also used as outgoing terminals at the primary side; the head ends of the A-phase, B-phase and C-phase secondary coils are used as the outgoing terminals (12), (13) and (14) at the secondary side, a binding terminal (11) is connected with the tail ends of the A-phase, B-phase and C-phase secondary coils. By adopting the structure, the solar inversion three-dimensional rolling iron core dry type transformer lead structure is especially suitable for connection of hanging type installed three-dimensional rolling iron core dry type transformer lead structures, is simple in structure and practical and attractive, saves space, meets installation customs of the traditional power supply, and is convenient to install.

Description

Solar energy inversion three dimensional wound core dry-type transformer pin configuration

Technical field

The utility model belongs to the technical field of power equipment, specifically is meant a kind of solar energy inversion three dimensional wound core dry-type transformer pin configuration.

Background technology

Traditional in the market three-phase transformer, primary side and secondary side lead-in wire offside are drawn.This kind outlet method has increased the overall dimension of transformer vertical and horizontal to a certain extent.In some specific occasions, like places such as locomotive, photovoltaic generations, stricter requirement all can be arranged for the profile of transformer and weight, the power transformer product that therefore is used for this occasion must compact conformation and in light weight.

The utility model content

The purpose of the utility model is to provide a kind of wiring construction simple, the solar energy inversion three dimensional wound core dry-type transformer pin configuration that draw primary side and secondary side lead-in wire both sides.

For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: solar energy inversion three dimensional wound core dry-type transformer pin configuration; A kind of solar energy inversion three dimensional wound core dry-type transformer pin configuration; It is made up of around the coil on the core limb A, B, C three-phase, and each phase coil is made up of primary winding and secondary coil respectively; Wherein the first head of A phase primary winding connects the tail head of C phase primary winding; The first head of B phase primary winding connects the tail head of A phase high-tension coil; The first head of C phase high-tension coil connects the tail head of B phase high-tension coil, simultaneously the first head of the first head of A phase primary winding, B phase primary winding, first double as primary side outlet terminal of C phase primary winding; A phase, B mutually and C the first head of secondary coil is as the secondary side outlet terminal mutually, binding post connects A phase, B mutually and the tail head of C secondary coil mutually.

A kind of solar energy inversion of the utility model three dimensional wound core dry-type transformer pin configuration; Owing to adopt such structure; This kind winding protruding head mode and pin configuration have effectively dwindled the horizontal and vertical overall dimension of transformer, have reduced the shared space of transformer.Be particularly suitable for the connection of the three dimensional wound core dry-type transformer pin configuration of suspension type installation, simple in structure, practical and attractive is saved the space, and meets traditional the power supply installation custom, convenient installation.

Description of drawings

Fig. 1 is the wiring sketch of the utility model primary winding;

Fig. 2 is the wiring sketch of the utility model secondary coil;

Fig. 3 is the stereogram of the utility model.

Embodiment

Be described in further detail below in conjunction with the embodiment of accompanying drawing, but do not constitute any restriction the utility model to the utility model.

Like Fig. 1, Fig. 2, shown in Figure 3; A kind of solar energy inversion of the utility model three dimensional wound core dry-type transformer pin configuration; Form around the coil on the core limb by A, B, C three-phase; Each phase coil is made up of primary winding and secondary coil respectively; It is as shown in Figure 3 that primary winding and secondary coil are lifted one's head the position, first 22 of A phase primary winding tail head 27 that connects C phase primary winding wherein, first 23 tail head 25 that connects A phase primary winding of B phase primary winding; First 24 of C phase primary winding tail head 26 that connects B phase primary winding, first 22 of A phase primary winding simultaneously, first 23 of B phase primary winding, first 24 double as primary side outlet terminal of C phase primary winding.

The first head of A phase, B phase and C secondary coil mutually is as secondary

side outlet terminal

12,13,14, and binding post 11 connects the tail head of A phases, B phase and C secondary coil mutually.

The primary side lead-in wire also can adopt star connection for delta connection, and low-voltage lead is a star connection.

The modes of emplacement of this kind binding post has effectively been saved the transformer locational space at both ends up and down, and then has dwindled the volume of transformer.

Above-described only is the preferential execution mode of the utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is regarded as the protection range of the utility model.
