Abstract
The utility model provides a transformer body structure of an amorphous alloy transformer, and comprises an amorphous alloy iron core and a rectangular coil. The utility model is characterized in that the utility model comprises a rectangular insulating framework arranged in a low tension coil, an insulating plate tightened between outphase high tension coils, clamping pieces at the both ends, insulating plates fixed on the clamping pieces at the both ends, an upper clamping piece, and a lower clamping piece. The coil is positioned on the lower clamping piece, the iron core is hung on the coil, the upper clamping piece and the lower clamping piece make the coil fixed and clamped, in addition, the high tension coils on the both sides and the iron core of a side column are tightened through the insulating plates fixed on the clamping pieces at the both ends. The utility model makes the radial force of the coil when the transformer shorts not oppress the amorphous alloy iron core, but be only transmitted to the rectangular framework and the clamping pieces at the both ends, thus the utility model is the transformer body structure of a rigid body frame, which has the short circuit resisting ability.
Description
(1) technical field
The utility model relates to the machine body structure of amorphous alloy transformer.
(2) background technology
Though existing amorphous alloy transformer can obtain application with its less good performance such as no-load loss, but, because amorphous alloy core can not bear the effect of mechanical force, in addition the mechanical strength of square coil a little less than, therefore the amorphous alloy transformer anti-short circuit capability is relatively poor, generally is difficult to the short circuit test by standard code.
(3) utility model content
The purpose of this utility model is to provide a kind of machine body structure that can improve anti-short circuit capability effectively, have the amorphous alloy transformer of rigid body framework.
A kind of machine body structure of amorphous alloy transformer, be made up of amorphous alloy core and square coil, it is characterized in that: it also is included in a rectangle insulation framework being provided with in the low-voltage coil, the insulation board at stretching between the high-tension coil of out-phase, two ends folder, fixing insulation board and upper and lower folder on the folder of two ends.Coil holder drops on the lower clamping piece, and iron core is suspended on the coil, and folder from top to bottom clamps coil stationary, in addition, carries out stretching by the insulation board that is fixed on the folder of two ends between both sides high-tension coil and the other post iron core.
Owing to adopted above-mentioned technical solution, a firm rectangle insulation framework is set in low-voltage coil, the alternate insulation board stretching of using of high-tension coil, between both sides high-tension coil and the other post iron core fagging is set, when transformer short-circuit, make the diametral force of coil not oppress amorphous alloy core, only reach rectangular framework and two ends folder, therefore, the utility model is the machine body structure with rigid body framework of anti-short circuit capability.
(4) description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
(5) embodiment
As shown in Figure 1, the utility model, i.e. a kind of machine body structure of amorphous alloy transformer, the unshakable in one's determination coiling with amorphous alloy strips forms, and adopts the square-section, four frame pentastyle structures.
Low-voltage coil adopts Copper Foil or copper cash coiling, and firm insulation framework 10 is set in low-voltage coil, and the inside electric power of extruding of interior loop is alleviated the excessive extruding force that the amorphous alloy core surface may be subjected to when contending with transformer short-circuit.High-tension coil directly is wound on the low-voltage coil.The high and low pressure coil is the rectangular coaxial layer coil.
The device body mainly is made of three-major-items: folder, coil 3, unshakable in one's determination 4.Upper clamping piece 2, lower clamping piece 9 and two ends folder 1 are coupled to the frame structure of rigid body.Coil holder drops on the lower clamping piece, presses nail 6 that coil is compressed on the upper clamping piece, prevents coil displacements, the axial electric power when overcoming transformer short-circuit.High-tension coil is alternate with insulation board 5 stretchings, uses insulation board 7 stretchings that are fixed on the folder of two ends between the other post iron core of both sides high-tension coil and non-crystaline amorphous metal.The characteristics of this kind machine body structure are that the radial electric power that high-tension coil expands outwardly during with transformer short-circuit reaches the two ends folder, bear the diametral force of high-tension coil by the two ends folder, thereby avoid other post iron core to be subjected to electrodynamic effect, strengthened the anti-short circuit capability of amorphous alloy transformer.
The utility model has the advantages that machine body structure compact and reasonable, volume are little, easy to assembly, axial at coil All have enough anti-short circuit capabilities with radial, and demonstrate,proved by the short-circuit test of many amorphous alloy transformers Real.
Claims (1)
1. the machine body structure of an amorphous alloy transformer, formed by amorphous alloy core and square coil, it is characterized in that: it also is included in a rectangle insulation framework being provided with in the low-voltage coil, the insulation board at stretching between the high-tension coil of out-phase, two ends folder, fixing insulation board and upper and lower folder on the folder of two ends, coil holder drops on the lower clamping piece, iron core is suspended on the coil, folder from top to bottom clamps coil stationary, in addition, carry out stretching by the insulation board that is fixed on the folder of two ends between both sides high-tension coil and the other post iron core.
