Abstract

The utility model discloses a single-phase reactor winding structure, which comprises an outer layer winding, an inner layer winding and an iron core, wherein four diagonal braces are arranged and connected between the iron core and the inner layer winding; an upper brace, a lower brace, an outer side brace and an inner side brace are arranged and connected between the outer layer winding and the inner layer winding; and the thickness of the outer side brace is larger than that of the inner side brace. Due to the adoption of the single-phase reactor winding structure disclosed by the utility model, the radiating condition of a winding is improved under the condition of keeping structural reliability, the radiating performance of a reactor is enhanced, temperature rise is reduced effectively, and heat energy loss is reduced.

Description

Single-phase reactor winding construction

Technical field

The utility model relates to the reactor technical field, is specifically related to a kind of single-phase reactor winding construction of improvement, is applied to play the secondary filtering effect in the auxiliary converter system of locomotive.

Background technology

Most single-phase reactor winding air flues all are evenly to place stay around adopting, and window width size unshakable in one's determination is bigger, and two windings face mutually in the window, and the air flue concurrent condition is relatively poor, and it is bad to dispel the heat.And the product weight restriction ratio that has is strict, and the requirement of customization is also very harsh, guarantee to guarantee that parameters comprises that temperature rise meets the requirements under the not overweight condition.

Temperature rise and weight are important parameters very in reactor and similar electronic product, especially use product ON TRAINS.In design reactor parameter, also to design the structure of reactor.The reactor structural design is unreasonable, can cause that inductance is saturated, temperature rise is too high, weight surpasses and defective such as require, and reactor is lossy in running; The ectonexine winding can generate heat, and the heat of generation distributes through ectonexine winding and air contact-making surface, but the heat of winding distributes least easily in window unshakable in one's determination; Because space relative closure; The cross-ventilation condition does not have the good of outside, so will make the whole better heat loss through convection of reactor, then must improve existing reactor structure.

Summary of the invention

The utility model technical problem to be solved is: solve the problem that above-mentioned prior art exists; And a kind of single-phase reactor winding construction of improvement is provided; Keeping improving the radiating condition of winding under the reliable structure situation, make the reactor heat dispersion better; Effectively reduce temperature rise, reduce heat energy loss.

The technical scheme that the utility model adopts is: this single-phase reactor winding construction; Comprise outer winding, internal layer winding and iron core; Install between iron core and the internal layer winding and be connected with four diagonal angle stays; Be connected with stay, following stay, outside stay and inboard stay and install between outer winding and the internal layer winding, outside stay thickness is greater than inboard stay thickness.

In the technique scheme, outside stay thickness is 2 times of inboard stay thickness.

In the technique scheme, the reactor winding conducting wire adopts aluminum conductor.

The utility model since outside stay thickness greater than inboard stay thickness; Thereby the air flue that makes the reactor winding is inhomogeneous is arranged in outside the window unshakable in one's determination; Improved the air flue concurrent condition; Make better heat loss through convection of reactor integral body, the heat in the window is dispersed into skin along the edge transfer of winding.Therefore, the utility model is keeping having improved the radiating condition of winding under the reliable structure situation, makes the reactor heat radiation better, effectively reduces intensification, has reduced heat energy loss, has prolonged reactor useful life, has improved the reactor technical performance.

Description of reference numerals:

The outer winding of 1-, 2-internal layer winding, 3-is unshakable in one's determination, the 4-air flue, 5-diagonal angle stay,

The last stay of 6-, stay under the 7-, 8-outside stay, the inboard stay of 9-.

Embodiment:

Referring to Fig. 1, Fig. 2; The single-phase reactor winding construction of the utility model, comprise outer winding 1, internal layer winding 2 and unshakable in one's determination 3, unshakable in one's determination 3 and internal layer winding 2 between install and be connected with four diagonal angle stays 5; Be connected with stay 6, following stay 7, outside stay 8 and inboard stay 9 and install between outer winding 1 and the internal layer winding 2; Outside stay 8 thickness are greater than inboard stay 9 thickness, and outside stay thickness is 2 times of inboard stay thickness, and the reactor winding conducting wire adopts aluminum conductor.

Because reactor is lossy in running; The ectonexine winding can generate heat, and the heat that produces distributes through ectonexine winding and air contact-making surface, and especially the heat of winding distributes least easily in window unshakable in one's determination; Because space relative closure; The cross-ventilation condition does not have the good of outside, so the stay in the utility model internal layer winding outside makes better heat loss through convection of reactor integral body than the inboard thick 12mm of stay.Heat in the window can be dispersed into skin along the edge transfer of winding, is keeping under the reliable structure situation, and the utility model has improved the radiating condition of winding, makes the reactor heat radiation better, and has the effect that reduces temperature rise.Simultaneously, the utility model reactor winding adopts aluminum conductor, has alleviated the weight of winding.

Stay uneven distribution around the utility model, outside stay thickness is 24mm, and inboard stay thickness is 12mm, and iron yoke length is 215mm then, has shortened iron yoke length, has alleviated iron yoke weight, has saved material and resource.
