Abstract
The invention relates to a manufacturing method for a saturable reactor and a discus used for a large rectifier transformer. According to the invention, the method not only can effectively prevent eddy-current and circulation losses of the, but also reduce the noise generated by silicon sheets at run-time. The saturable reactor comprises a discus, a bracket, a copper bar and an oil tank, wherein the bracket is made from a non-magnetic material, shelves of the bracket use a partition magnetic circuit closed ring to avoid the eddy-current and circulation losses; a paint film is arranged between the silicon sheets in the discus; unidrectional binding tape tension devices are arranged between lower pressing plates on the discus. The invention has the advantages that the shelves adopt the partition magnetic circuit closed ring to avoid the eddy-current and circulation losses; and the iron core adopts a vacuum pressure impregnating vanish treatment to reduce the noise generated by the silicon sheets at run-time.
Description
Technical field
The present invention relates to a kind of generation that can prevent reactor eddy current and circulation loss effectively, the large rectifier transformer that silicon steel sheet produces noise in the time of reducing operation again belongs to large rectifier transformer and makes the field with saturable reactor with saturable reactor and discus manufacture method.
Background technology
At present, the type rectifier transformer is that discus rolls with up-coiler with the traditional method one of saturable reactor, unreels part and provides tension force with a brake rubber block, if brake rubber block tension force deficiency causes discus to roll not enough consolidation easily; If brake rubber block overtension one is a coil winding machine not necessarily draw moving, the 2nd, silicon steel sheet is also had certain damage.And in winding process, the situation of pausing in the middle of can occurring unavoidably, coil winding machine one stops, and silicon steel sheet is just loose; The 2nd, discus is dipping lacquer (only being to be coated with the end face lacquer) or antivacuum dipping lacquer not, and it is not fine causing the insulating varnish infiltration; The 3rd, adopt the screw rod tension to compress discus between discus pressing plate up and down, doing the problem of bringing like this is that when saturable reactor moved, because circulation appears in the generation of a large amount of leakage fields on metalwork, metalwork generated heat easily.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of generation that can prevent reactor eddy current and circulation loss effectively, can reduce when operation silicon steel sheet large rectifier transformer of producing noise again with saturable reactor and discus manufacture method.
Design: in order to realize above-mentioned purpose of design.1, adopt import orientation silicon steel sheet, the uninterrupted coiling forms, and vacuum annealing is handled, reach the silicon steel sheet lowest loss and improve magnetic property, because the voltage of large rectifier transformer is low, and electric current is very big, so leakage field is just very big, in order to reduce the eddy current loss that leakage field produces, we adopt new structure at this reactor, and fixed mount adopts no magnetic material, and all shelfs all adopt and cut off the magnetic circuit closed hoop, prevent the generation of eddy current and circulation loss, thereby reach the purpose that reduces the wastage.2, iron core adopts vacuum pressure impregnation to handle, and silicon steel sheet produces noise when reducing operation.By traditional screw rod take-up device, used no latitude band take-up device instead, effectively reduce noise.
Technical scheme 1: a kind of large rectifier transformer saturable reactor, it comprises discus, support, copper bar and fuel tank, and described support is no magnetic material, and its shelf adopts and cuts off the generation that the magnetic circuit closed hoop prevents eddy current and circulation loss; Be equipped with paint film between the silicon steel sheet in the described discus; Adopt no latitude band take-up device between the lower platen on the described discus.
Technical scheme 2: a kind of large rectifier transformer saturable reactor discus manufacture method, discus adopts the coiling of automatic paper tinsel formula coil winding machine, all adopt argon arc welding spot welding before and after the coiling, the intact iron core of coiling adopts volume core annealing technology to carry out annealing in process, it is that the vacuum pressure pouring can of 0.15-0.5mpa carries out vacuum pressure impregnation and handles that iron core after the annealing is put into pressure, make face dipping lacquer between the silicon steel sheet, adopt the transformer curing oven to carry out the hot setting processing behind the dipping lacquer and get final product.
The present invention compares with background technology, and the one, shelf all adopts and cuts off the magnetic circuit closed hoop, prevents the generation of eddy current and circulation loss; The 2nd, the vacuum pressure impregnation that adopts unshakable in one's determination is handled, and silicon steel sheet produces noise when reducing operation.
