Abstract
The utility model relates to an annular tapping disk structure for a traction transformer, which belongs to the technical field of transformers. The utility model has the technical scheme that the annular tapping disk structure for the traction transformer comprises basic coil tapping joint inserts (1), a tapping piece fulcrum (2), phase-shifting coil tapping joint inserts (3) and a tapping piece (4); the tapping piece is fixed on the tapping piece fulcrum; and the two ends of the tapping piece are respectively fixed on the basic coil tapping joint inserts and the phase-shifting coil tapping joint inserts through screw bolts. The annular tapping disk structure has the positive effects that the defects of tedious adjustment work and insufficient space for tapping are overcome; and a basic coil and a phase-shifting coil are correspondingly tapped at the corresponding positions of a disk, so that the tapping can be quickly and simultaneously adjusted so as to save space, and the lead structure becomes simple.
Description
Technical field
The utility model relates to a kind of annular tap dish structure that is used for traction transformer, belongs to the transformer technology field.
Background technology
Urban light rail adopts the structure of net sidesway phase ± 7.5 ° with traction rectifier transformer, and the traction transformer separate unit is 12 arteries and veins transformers, two sections parallel connections of net lateral coil, so each net lateral coil is made up of four small coils.Owing to require basic coil and phase shift coil all can adjust tap; Therefore; Background technology often each net lateral coil has four components to connect the adjustment structure; The problem that exists is: the work when transferring tap of such structure is loaded down with trivial details, and small-capacity product coil space outerpace is less, arranges that so many tap adjustment structure has difficulties.
The utility model content
The purpose of the utility model provides a kind of annular tap dish structure that is used for traction transformer, can adjust tap fast simultaneously, saves the space, and pin configuration becomes simply the problems referred to above that the solution background technology exists.
The technical scheme of the utility model is:
A kind of annular tap dish structure that is used for traction transformer; Comprise the basic coil tap inserts, branch contact pin fulcrum, phase shift coil tap inserts, the branch contact pin that are arranged on the disk body; Divide contact pin to be fixed on the branch contact pin fulcrum, divide the contact pin two ends to be separately fixed on basic coil tap inserts and the phase shift coil tap inserts through bolt.
A plurality of basic coil tap inserts and phase shift coil tap inserts are circumference on disk body.
Basic coil tap inserts is connected with the basic coil tap of transformer, and phase shift coil tap inserts is connected with transformer phase shift coil tap.
Adopt the utility model; The tap of basic coil and phase shift coil drawn respectively be connected to corresponding inserts; Divide the corresponding winding protruding head of inserts that contact pin connects promptly to become first and the tail head of phase shift coil of fundamental line circle; Require this common point drawn according to connection set and be connected to the corresponding tail head of basic coil mutually, promptly accomplish extend-triangle and connect.When needing the adjustment tap, take off the fixing bolt that divides contact pin of basic coil tap inserts and phase shift coil tap inserts, rotate basic coil tap inserts and phase shift coil tap inserts, fixing again getting final product to corresponding tap position.
The good effect of the utility model is: solved the defective of the loaded down with trivial details and insufficient space of tap adjustment work, with basic coil and the corresponding correspondence position at disk of phase shift coil tap, can adjust tap fast simultaneously, save the space, and pin configuration has become simple.
Description of drawings
Fig. 1 is the utility model embodiment sketch map;
Among the figure: 1. basic coil tap inserts, 2. minute contact pin fulcrum, 3. phase shift coil tap inserts, 4. minute contact pin.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
A kind of annular tap dish structure that is used for traction transformer; Comprise the basic coil tap inserts 1, branch contact pin fulcrum 2, phase shift coil tap inserts 3, the branch contact pin 4 that are arranged on the disk body; Divide contact pin to be fixed on the branch contact pin fulcrum, divide the contact pin two ends to be separately fixed on basic coil tap inserts and the phase shift coil tap inserts through bolt.A plurality of basic coil tap inserts and phase shift coil tap inserts are circumference on disk body.Basic coil tap inserts is connected with the basic coil tap of transformer, and phase shift coil tap inserts is connected with transformer phase shift coil tap.
