The technical scheme is as follows that the current by-pass structure comprises an upper clip (4), a lower clip (5), electrical cables (2), a pulling board (6), an iron core (7), wherein the upper clip and the lower clip are respectively disposed on the upper end and the lower end of the iron core, both ends of the pulling board are attached to the upper clip and the lower clip, and are arranged in parallel with the iron core, both ends of the electric cable are also attached to the upper clip and the lower clip, and connected in parallel with the pulling board, and a novel current by-pass circuit is formed between the electric cables and the iron core clip. The beneficial effect of the utility model is that a novel current by-pass circuit is formed between the electric cable and the iron core clip through the parallel attachment between the electric cable and the pulling board, so that the circulation current pass through the pulling board is reduced, eddy flow loss within the iron core pulling board of the converter transformer is reduced, and the by-pass pulling board with relatively smaller current blocking area is prevented from being overheated. The internal circulation by-pass structure overcomes the shortcoming of the technique in the prior art, has simple structure and little occupied space, can effectively solve the problem that several members are overheated because of overcurrent for circulation current within the iron core frame of the ultra-high voltage converter transformer.
Description
Affiliated technical field:
The utility model relates to circulating current bypass structure in a kind of ultra high voltage converter transformer framework unshakable in one's determination, belongs to technical field of transformer manufacturing.
Background technology:
High-voltage commutation transformer core framework is made of parts such as upper clamping piece, lower clamping piece, arm-tie, fagging, pad pin, when the change of current becomes normal operation, be in the inner circulating current that can produce to a certain degree of framework unshakable in one's determination in the magnetic field, for the high-voltage commutation transformer, the circulating current numerical value that near the folder great current lead wire causes in framework unshakable in one's determination is less, and framework eddy current loss unshakable in one's determination is within tolerance band; But for the ultra high voltage converter transformer, the initiation circulating current numerical value of great current lead wire in framework unshakable in one's determination is bigger near the folder, and framework eddy current loss unshakable in one's determination is bigger, at indivedual less parts of current-carrying area, as other post arm-tie, is prone to potential safety hazards such as overheated.Former high-voltage commutation becomes the iron core frame shelf structure can not be applicable to the ultra high voltage converter transformer, Given this, needs the iron core frame shelf structure is improved.
The utility model content:
The utility model purpose provides circulating current bypass structure in a kind of ultra high voltage converter transformer framework unshakable in one's determination, and simple in structure, it is little to take up space, and can effectively solve the overheated problem of the excessive initiation individual component of circulating current in the ultra high voltage converter transformer framework unshakable in one's determination
The technical solution of the utility model is:
The circulating current bypass structure comprises upper clamping piece, lower clamping piece, cable, arm-tie, iron core in the ultra high voltage converter transformer framework unshakable in one's determination, upper clamping piece, lower clamping piece are separately positioned on top and bottom unshakable in one's determination, the arm-tie two ends are connected on upper clamping piece and the lower clamping piece, be arranged in parallel with iron core, the two ends of cable also are connected with lower clamping piece with upper clamping piece, in parallel with arm-tie, between cable and core clamping, form new current bypass.
Said cable is in parallel with arm-tie, is valve side upper clamping piece is connected by cable with net side lower clamping piece with valve side lower clamping piece and net side upper clamping piece.
The utility model also is provided with fixed head and pressure joint, and fixed head is separately fixed on upper clamping piece and the lower clamping piece, and the cable two ends are provided with pressure joint, and pressure joint is arranged on the fixed head.
The cable quantity of the utility model setting is arbitrarily, and for example: four jiaos of frameworks unshakable in one's determination one group of cable is set respectively, totally four groups of cables, every group of cable all are provided with up and down two fixed heads and pressure joint, amount to eight fixed heads and pressure joint.
The beneficial effects of the utility model are as follows: in parallel with arm-tie by cable, between cable and core clamping, form new current bypass, thereby reduce the circulating current of the arm-tie of flowing through, reduce eddy current loss in the convertor transformer arm-tie unshakable in one's determination, avoid the less other post arm-tie of current-carrying area overheated.The utility model overcomes the deficiency of prior art, and is simple in structure, and it is little to take up space, and can effectively solve the overheated problem of the excessive initiation individual component of circulating current in the ultra high voltage converter transformer framework unshakable in one's determination.
