Abstract
The utility model relates to a saturable reactor for a large-scale rectifier transformer, which can effectively prevent the loss of both eddy current and circulating current and reduce noise generated by silicon sheets during operation. 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 adopt partition magnetic circuit closed rings to prevent the loss of both eddy current and circulating current; paint films are arranged among the silicon sheets in the discus; and non-latitude belt tightening devices are arranged among lower pressing plates on the discus. The utility model has the advantages that firstly, all the shelves adopt partition magnetic circuit closed rings to prevent the loss of both eddy current and circulating current; and secondly, an iron core is subjected to vacuum pressure paint dipping, so that noise generated by the silicon sheet in the operation is reduced.
Description
Technical field
The utility model relates to a kind of generation that can prevent reactor eddy current and circulation loss effectively, and silicon steel sheet produces the large rectifier transformer saturable reactor of noise in the time of reducing operation again, belongs to large rectifier transformer and makes the field with saturable reactor.
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.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of reactor eddy current and circulation loss of can preventing effectively and produce the large rectifier transformer saturable reactor that the silicon steel sheet noise produces in the time of reducing operation again.
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: 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.
The utility model is compared 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.

Fig. 1 is the structural representation of large rectifier transformer with saturable reactor.
Fig. 2 is the side-looking structural representation of Fig. 1.
Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.A kind of large rectifier transformer saturable reactor, it comprises discus 1, support 2, copper bar 3 and fuel tank, and described support 2 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 1; Adopt no latitude band take-up device between the lower platen on the described discus 1.Described no latitude band epoxy resin dipping glue-line.Its large rectifier transformer is with 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.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model simple text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection range of the present utility model.
