Abstract
The utility model relates to a transformer coil, in particular to a full continuous transformer coil with an angle ring, which does not have welding heads or shielding wires among sections. The full continuous transformer coil comprises a paper barrel, one side of the paper barrel is provided with a stay, a coil is wound on the stay, the stay is divided into a negative section I, a positive section I, a negative section II and a positive section II, the negative section I is connected with the positive section I, the positive section I is connected with the negative section II, the negative section II is connected with the positive section II, and at least one of the positive section I, the negative section II and the positive section II is provided with the angle ring. The full continuous transformer coil is compact in structure and fine in radiating effect, can guarantee electrical strength of the coil, increases winding technique of the coil, shortens coil winding time, increases coil filling rate and strengthens whole mechanical strength of the coil.
Description
Technical field
The utility model is a kind of transformer coil, and particularly a kind of intersegmental nothing is entangled with the fully continuous type transformer coil that has square ring of the unshielded line of plumb joint.
Background technology
Of the prior art in electric power system, can't stand this overvoltage and damaged when reasons such as atmospheric over-voltage (impact to wait to cause as thunderbolt) can cause that transformer coil holds.Be head it off, the winding method of traditional 110kV, 220kV transformer coil is as follows: 1. adopt and be entangled with continous way, welding again after the place of being entangled with needs lead cut off in this method coil will increase coiling man-hour like this, also be not easy to take up, thereby can reduce the coil mechanical strength.2. adopt the inner shield continous way, this method requires to insert shielding conductor between the circle of active line, and whole space availability ratio is reduced, and during coiling shielding conductor not with active line around, thereby need to increase winding process, manufacturing cost is increased.
Chinese patent CN2327055 discloses a kind of improved small distribution transformer coil.The utility model belongs to the parts of transformer, particularly the small distribution transformer coil.This coil is formed on the basis at existing coil, paper web and insulating paper, changes traditional cylindrical layer winding into more than two sections coiling, has paper circle and cardboard cushion block to separate between every section coil, is set with paper circle and cardboard cushion block at the two ends of paper web.Transformer coil described in this utility model is to adopt the company of being entangled with, and the coil overall mechanical strength is low, and the coiling time is long, and the transformer coil heat dispersion is poor.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of fully continuous type transformer coil that has square ring that is provided with intersegmental axial oil duct and square ring on transformer coil is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of fully continuous type transformer coil that has square ring, comprise paper web, one side of paper web is provided with stay, be wound with coil on the stay, described stay is divided into anti-section I, positive section I, anti-section II and positive section II, an anti-section I and a positive section I are connected, positive section I is connected with an anti-section II, anti-section II and a positive section II are connected, and described positive section I, anti-section II and a positive section II are provided with square ring for last at least one section.
As preferably, be respectively equipped with square ring on described positive section I, anti-section II and the positive section II, described square ring is located at the outer end of the inner and positive section II of the outer end of positive section I, anti-section II respectively.
As preferably, be respectively equipped with intersegmental axial oil duct on described anti-section I, positive section I, anti-section II and the positive section II, described intersegmental axial oil duct comprises paperboard strip, and the two ends of paperboard strip and centre are respectively equipped with the paper washer piece, and described paper washer piece and paperboard strip are bonding.
Therefore, the utility model provides the fully continuous type that has square ring transformer coil, compact conformation, good heat dissipation effect can guarantee coil electric intensity, increases the coil winding manufacturability, shorten coil winding man-hour, raising coil filling rate and energy intensifier coil overall mechanical strength.
