Abstract
The invention relates to the technical field of a transformer coil, in particular to a shaping method of an amorphous alloy transformer coil, which comprises the following steps that I, a wound coil is placed on a pressing plate in a hoisting manner; II, a beforehand shaping mold is installed for preparing for compression shaping of a radial straight part of the coil; III, a bolt on the shaping mold is screwed down, the geometric dimension of the coil is measured by a ruler, and the bolt is not tightened until the geometric dimension meets the dimension requirement; IV, the coil and the shaping mold are placed into a drying tank to be dried, and the drying time is 8-12 hours; and V, after the coil is discharged, the boundary dimension of the coil is checked, and the qualified coil is stored for standby use. The method has the characteristics that firstly, an existing crane and an existing drying system are adopted without adding new equipment, so that the overlapping phenomenon of wires is avoided, and the measurement size precision of every other turns is ensured; secondly, the phenomenon that bound insulation layers cannot wrap the coil is avoided, and the electric insulation strength is improved; and finally, a large number of raw materials are saved, and the product quality and the production efficiency are effectively improved.
Description
Technical field
The present invention relates to the transformer coil technical field, be specifically related to the amorphous alloy transformer coil shaping methods.
Background technology
Nowadays, transformer coil all needs through shaping process after coiling is finished usually, as not adopting shaping process, then be prone to wire overlapping, every circle measurement size inaccuracy, easily cause insulating wrapping number of plies bag do not enter, affect electric insulation intensity, breakdown between adjacent turns rate high, make its a large amount of waste of raw materials, affect product quality and production efficiency.
Summary of the invention
The purpose of this invention is to provide that a kind of technique is simple, step is easy, easy to operate, avoid the wire overlapping phenomenon occurring, guarantee every the circle measurement size accurately, Effective Raise electric insulation intensity and improving the quality of products and the amorphous alloy transformer coil shaping methods of production efficiency.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the amorphous alloy transformer coil shaping methods may further comprise the steps:
(1), the coil of coiling being finished hangs on pressing plate;
(2), preprepared shaping mould is installed, prepare the shaping of pressurizeing of the radial straight line portion of coil;
(3), tighten the bolt on the described shaping mould, the physical dimension with the ruler measuring coil is fastened to till the requirement that meets size;
(4), together with described coil, shaping mould, put into drying chamber dry, be 8～12 hours drying time;
(5), come out of the stove after, check the coil shape size, deposit after qualified, stand-by.
The present invention has following beneficial effect: amorphous alloy transformer coil shaping methods of the present invention, has following characteristics, at first adopt existing crane and drying system, need not increases new equipment, avoid occurring the wire overlapping phenomenon, guarantee accurate every the circle measurement size; Secondly, avoid causing the insulating wrapping number of plies bag phenomenon of not entering, improve electric insulation intensity; At last, save a large amount of raw material, and Effective Raise product quality and production efficiency.In addition, the present invention has the characteristics such as technique is simple, step is easy, easy to operate, mainly is applicable to voltage 10KV level, range of capacity is the radial shaping of 30～1600Kva oil immersed amorphous alloy iron core transformer coil.
