Abstract
The invention discloses a lead structure of a suspended C-level three-dimensional wound core dry-type transformer and belongs to the technical field of power equipment. The lead structure of the suspended C-level three-dimensional wound core dry-type transformer consists of an A-phase coil, a B-phase coil and a C-phase coil which are wound on a core limb. Each phase coil respectively consists of a high-voltage coil and a low-voltage coil. Three wire connecting terminals (31, 32, 33) of the high-voltage coils and four wire connecting terminals (41, 42, 43, 44) of the low-voltage coils are respectively arranged on lead brackets (1) positioned at both sides of the transformer, wherein a head end of the A-phase high-voltage coil is connected with the wire connecting terminal (31) and a tail end of the C-phase high-voltage coil; a head end of the B-phase high-voltage coil is connected with the wire connecting terminal (32) and a tail end of the A-phase high-voltage coil; a head end of the C-phase high-voltage coil is connected with the wire connecting terminal (33) and a tail end of the B-phase high-voltage coil; three wire connecting terminals (41, 42, 43) of the low-voltage coils are respectively connected with the head ends of the three low-voltage coils; and the wire connecting terminal (44) is connected with the tail ends of the three low-voltage coils.
Description
Technical field
The invention belongs to the technical field of power equipment, be meant that specifically a kind of high pressure is that delta connection, low pressure are the three dimensional wound core dry-type transformer pin configuration of star connection, Y connection.
Background technology
Traditional in the market Pedestal mounted three-phase transformer, high and low pressure lead-in wire offside is drawn, and makes things convenient for terminal block.The three dimensional wound core dry-type transformer wiring for the convenience of the user that suspension type is installed, the offside that also high and low pressure must be gone between is drawn, but as the connecting method of lead-in wire when adopting conventional planar to arrange, will cause the wiring complexity, in disorder, problem such as big takes up room.In addition, three dimensional wound core low pressure is because reasons in structure is difficult for the D.C. resistance balance.
Summary of the invention
The object of the present invention is to provide a kind of wiring construction simple, the three dimensional wound core dry-type transformer pin configuration that draw high and low pressure lead-in wire both sides.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of three dimensional wound core dry-type transformer pin configuration is by A, B, the C three-phase is formed around the coil on the core limb, each phase coil is made up of high-tension coil and low-voltage coil respectively, three binding posts of high-tension coil and four binding posts of low-voltage coil are arranged in respectively on the down-lead bracket that is positioned at the transformer both sides, wherein the first head of A phase high-tension coil connects the tail head of binding post and C phase high-tension coil, the first head of B phase high-tension coil connects the tail head of binding post and A phase high-tension coil, and the first head of C phase high-tension coil connects the tail head of binding post and B phase high-tension coil; Three binding posts of low-voltage coil connect the first head of three low-voltage coils respectively, and binding post connects the tail head of three low-voltage coils.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, and user's wiring when making things convenient for the transformer suspension type to install.
Owing to adopted above-mentioned structure, wherein the first circle double as transition lead-in wire of two-phase high-tension coil causes on the binding post of the same side high pressure three phase terminals, and low-voltage lead causes on the binding post of opposite side of high-voltage connection terminal.The present invention is suitable for three dimensional wound core dry-type transformer lead-in wire and connects, and is particularly suitable for the connection of the three dimensional wound core dry-type transformer pin configuration of suspension type installation, and is simple in structure, practical and attractive, saves the space.The set-up mode 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, and user's wiring when making things convenient for the transformer suspension type to install.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail, but does not constitute any limitation of the invention.
As Fig. 1, Fig. 2, shown in Figure 3, described 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 high-tension coil and low-voltage coil respectively, and high-tension coil has three binding posts 31,32,33 and low-voltage coil to have four binding posts 41,42,43,44 to be arranged in respectively on the down-lead bracket 1 that is positioned at the transformer both sides;
Wherein the first head of A phase high-tension coil connects the tail head of binding post 31 and C phase high-tension coil, the first head of B phase high-tension coil connects the tail head of binding post 32 and A phase high-tension coil, and the first head of C phase high-tension coil connects the tail head of binding post 33 and B phase high-tension coil;
Three binding posts 41,42,43 of low-voltage coil connect the first head of three low-voltage coils respectively, and binding post 44 connects the tail head of three low-voltage coils.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, and user's wiring when making things convenient for the transformer suspension type to install.
In the present invention, high-voltage connection is a delta connection, also can adopt star connection; Low-voltage lead is a star connection.
Above-described only is preferential execution mode of the present invention.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
