Abstract
A zigzag phase-shifting insulating structure of a rectifier transformer comprises a low voltage coil, a basic coil and a phase-shifting coil, wherein the basic coil and the phase-shifting coil are arranged on the same main hollow channel and are respectively an upper portion and a lower portion of a coil in the same main hollow channel, the amplitude sizes of the basic coil and the phase-shifting coil are basically consistent, and an insulator is arranged between the tail segment of the basic coil and the initial segment of the phase-shifting coil. The zigzag phase-shifting insulating structure of the rectifier transformer improves the reliability of the rectifier transformer, and meanwhile, leads the insulating radius of the coil to be reduced because of reducing a main hollow channel, thereby reducing material consumption, saving material cost, and since the structure is simplified, thereby improving the working efficiency of products, and saving labor cost.
Description
[technical field]
The utility model relates to a kind of insulation system of transformer, particularly a kind of phase shift insulation system that is applicable to rectifier transformer after improving.
[background technology]
Along with the fast development of Chinese national economy, the electrochemistry industry of China has also obtained fast development.The maximum characteristics of electrochemistry industry are that interchange is become direct current, then non-ferrous metal compound or salt etc. are carried out electrolysis, to produce products such as aluminium, copper, zinc or chlor-alkali.In the process of AC-DC, system can produce a large amount of high order harmonic components, if these high order harmonic components are injected public electric wire net, the electrical network quality of power supply is descended.In order to address this problem, often need the rectifier transformer in the system is carried out phase shift, with the more relatively pulse number of acquisition, thereby reduce the harmonic content that injects public electric wire net.At present, the most frequently used phase shift system has indentation phase shift, extend-triangle phase shift and hexagon phase shift etc., selects for use according to the difference of the mode of connection.
For the indentation phase shift, the branch of phase shift of voltage regulating transformer indentation and the phase shift of rectifier transformer indentation is arranged again.
At present, the insulation system schematic diagram of existing rectifier transformer indentation phase shift as shown in Figure 3, phase shift coil 2, basic coil 3, low-voltage coil 4 are separately positioned in three adjacent main empty paths 11,12,13, this insulation system, when the phase shift angle was less, the width of cloth of phase shift coil can become very thin to size (shown in B among Fig. 3), and compressing of coil is difficult to guarantee to put in place, make the stability and the anti-short circuit capability of coil all relatively poor, thereby reduced the reliability of transformer.
[utility model content]
The purpose of this utility model is to provide the indentation phase shift insulation system of the rectifier transformer after a kind of the improvement, move down to solve the less situation of transformer phase shift angle that the width of cloth of phase coil is thin partially to size, coil compress be difficult to guarantee to put in place, the stability and all relatively poor problem of anti-short circuit capability of coil.
The technical solution of the utility model is: a kind of indentation phase shift insulation system of rectifier transformer, comprise low-voltage coil, basic coil and phase shift coil, described basic coil and phase shift coil are arranged in same main empty path and are respectively two parts up and down of same main empty path coil, the width of cloth of described basic coil and phase shift coil is provided with insulator to the size basically identical between first section of the latter end of basic coil and phase shift coil.
Its further technical scheme is: the insulator that is provided with between first section of the latter end of described basic coil and phase shift coil is that U-shaped paper groove adds cross-over block and transformer oil.
The indentation phase shift insulation system of the rectifier transformer of the utility model is compared with the insulation system of existing rectifier transformer indentation phase shift, lacked a main empty path, the width of cloth that has not only solved phase shift coil in the original insulation system effectively is thin partially to size, the stability and all relatively poor problem of anti-short circuit capability of coil, has also improved the reliability of transformer; Simultaneously,, the insulation radius of coil is reduced, thereby reduced material consumption, saved material cost owing to reduced by a main empty path; And, owing to simplify the structure, thereby improved the operating efficiency that product is made, saved human cost.

Fig. 1 is the structural representation of indentation phase shift insulation system of the rectifier transformer of the utility model;
Fig. 2 is a kind of insulator structure schematic diagram that is provided with between first section of the basic coil latter end of indentation phase shift insulation system of rectifier transformer of the utility model and the phase shift coil;
Fig. 3 is the structural representation of the indentation phase shift insulation system of existing a kind of rectifier transformer.
[embodiment]
Below, the indentation phase shift insulation system to the rectifier transformer of the utility model is further described in conjunction with the accompanying drawings and embodiments.
As shown in Figure 1, the indentation phase shift insulation system of the utility model rectifier transformer comprises transformer core 1, low-voltage coil 4, basic coil 3 and phase shift coil 2, described basic coil 3 is arranged in same main empty path 11 with phase shift coil 2 and is respectively two parts up and down of same main empty path 11 coils, described low-voltage coil 4 is positioned at another main empty path 13, the width of cloth of described basic coil 3 and phase shift coil 2 is to size (shown in A among Fig. 1) basically identical, because relative the increasing of voltage between first section of described basic coil latter end and the phase shift coil, so between first section of described basic coil latter end and phase shift coil, be provided with the insulator that is used to insulate, this insulator is the structure (as shown in Figure 2) that U-shaped paper groove 6 adds cross-over block 5 and transformer oil in the present embodiment, and simultaneously the width c of the oil duct 7 between 2 first sections of described basic coil 3 latter ends and phase shift coils should suitably strengthen.
Owing to adopt said structure, under the less situation of transformer phase shift angle, the basic coil 3 of the indentation phase shift insulation system of the utility model rectifier transformer is bigger to size (shown in B among Fig. 3) than the width of cloth of existing phase shift coil to size (shown in A among Fig. 1) with the width of cloth of phase shift coil 2, and the width of cloth that efficiently solves phase shift coil in the original insulation system is thin partially to size, the stability and all relatively poor problem of anti-short circuit capability of coil.
