Abstract

A dry transformer coil air way structure comprises an air way line crossing rib, an air way, an air way outer wall and an air way inner wall. The dry transformer coil air way structure is characterized in that the air way line crossing rib is arranged in the air way, and the air way line crossing rib is arranged at a wiring connecting plate between the air way outer wall and the air way inner wall. According to the dry transformer coil air way structure, the air way line crossing rib is arranged at the wiring connecting plate between the air way outer wall and the air way inner wall in a concentrating mode, and electric breakdown caused by the fact that transition guiding wire insulation distance of the inner wall and the outer wall because of insufficient air way line crossing rib space can be avoided during pouring piece and mould assembling.

Description

Dry-type transformer coil air passage structure
Technical field
The utility model relates to transformer structure, particularly a kind of dry type transformation coil airway structure.
Background technology
Existing dry-type transformer, it is all by the circumference quartering that its coil airway is crossed line muscle, as shown in Figure 2, the shortcoming of this structure is that air flue is crossed line muscle and distributed too much, in reality, only need to use a place, utilance is low, has reduced effective air flue area, and to cross line muscle space little at every place, while crossing line from inwall to outer wall, because bulk is less than normal, cause transition wire insulation distance to form not electric puncturing.
Summary of the invention
The purpose of this utility model is just to provide the dry-type transformer coil air passage structure that a kind of security performance is high.
Dry-type transformer coil air passage structure of the present utility model, comprise that air flue crosses line muscle, air flue, air flue outer wall and air flue inwall, it is characterized in that, an air flue is set in air flue and crosses line muscle, described air flue is crossed line muscle and is arranged in the terminal block place between air flue outer wall and air flue inwall.
Dry-type transformer coil air passage structure of the present utility model, air flue is crossed the terminal block place of line muscle centralized arrangement between air flue outer wall and air flue inwall, in the time of avoiding pouring piece and die assembly, it is inadequate that air flue is crossed line muscle space, causes inwall to the transition lead wire insulation distance of outer wall to cause not electric puncturing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is existing dry-type transformer coil air flue schematic diagram.
Embodiment
A kind of dry-type transformer coil air passage structure, comprise that air flue crosses line muscle 1, air flue 2, air flue outer wall 3 and air flue inwall 4, it is characterized in that, an air flue is set in air flue 2 and crosses line muscle 1, described air flue is crossed line muscle 1 and is arranged in the terminal block place between air flue outer wall 3 and air flue inwall 4.
