Abstract
The utility model relates to a reactor with conductor layer contour enveloping insulation which belongs to a non magnetic core reactor. The utility model is suitable for an air-cooled dry-typed reactor. The utility model comprises a coil, an upper bus bar, a lower bus bar, an insulation prop, etc. The utility model is characterized in that besides the innermost conductor layer of the coil, the conductor layers of the coil are all padded with insulating pad strips which can make the close windings of the conductor layers have equal height; the insulating pad strips of the conductor layers of the same encapsulation are evenly distributed and have same position. The utility model solves the problems in prior art that manufacturability is poor, the electrical inductance value is inaccurate, the insulating strength is low, the operational reliability is poor, etc.
Description
The utility model belong to power supply with or the no magnetic core reactor of prescribed use not, mainly be applicable to air cooled dry reactor, as current limiting reactor, series reactor, shunt reactor, starting reactor, test reactor, smoothing reactor, filter reactor etc.
Existing conductor layer is contour holds the insulation reactor, by coil, go up bus-bar, bus-bar, electroceramics pillar etc. constitute down.Its objective is to the networking reactance is provided.Its weak point is: 1, for reaching the contour purpose of each conductor layer that constitutes coil, coil except that inside conductor layer, all the other each conductor layers are even need rare around, cause the displacement of adjacent layer lead, make every layer conductor around injustice, and increased adjacent layer turn-to-turn voltage, reduced dielectric strength; 2, rarely fill by the fiber that is coated with insulating cement, not only fill out unreally, form air gap easily, guiding discharge, the reliability that seriously endangers reactor around locating the turn-to-turn space; 3, coil upright around the time, pile under the whole winding, the whole winding lower diameter is increased, make inductance value overproof, manufacturability is relatively poor.
The purpose of this utility model is to overcome the weak point in the prior art, and provide dielectric strength height, good manufacturability, inductance value accurately, conductor layer that operational reliability is high contour hold the insulation reactor.
The purpose of this utility model can reach by following measure: it comprises coil, goes up bus-bar, bus-bar, insulation column etc. down, and its special character is: all be lined with in all the other each conductor layers except that inside conductor layer in coil and make each conductor layer close around highly identical insulation filler strip; Even distribution of insulation filler strip in each conductor layer in same sealing and position are identical.Like this, change the width and the quantity of insulation filler strip in each conductor layer, make all closely coilings of lead in each conductor layer, and the height of each conductor layer is equated.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the coil half-sectional view of the utility model embodiment;
See figures.1.and.2, be multi-layer cylinder formula structure by several 8 coils that constitute 1 of sealing, each is sealed 8 and is made up of 1-6 layer drum type brake conductor layer 7.7 of per two conductor layers are surrounded with insulating cement bundle 6 as layer insulation, and scribble insulating cement 10 and fill each turn-to-turn space, become a firm integral body after coil 1 is solidified.Present embodiment adopts and is soaked with rare latitude of resin glue or does not have the latitude glass tape as insulation micella 6, adopts epoxy resin or polyester as insulating cement 10.Seal 8 by stay 9 supports, dispel the heat for per two to form cooling airway.Last bus-bar 2 and following bus-bar 3 place the top and bottom of coil 1 respectively and connect with coil electric.Last bus-bar 2 and following bus-bar 3 are tightly wrapped by insulation micella 11 each other 1 of coil.Insulation micella 11 solidifies with the insulation micella 6 and the insulating cement 10 of 7 of conductor layers, to strengthen the overall mechanical strength of product.The insulation micella 11 of present embodiment is to adopt the no latitude glass fiber micella that is soaked with insulating cement.Outstanding feature of the present utility model is to begin at from inside to outside several second conductor layers of coil 1, is lined with insulation filler strip 5 in each conductor layer 7, and is identical in same position of sealing the filler strip 5 that respectively insulate in 8, can be different in the different positions of sealing insulation filler strip 5 in 8.7 li of same conductor layers, insulation filler strip 5 evenly distributes.Sealing of ragged edge has 3 insulation filler strips 5, each 1/4th, 1/2nd, 3/4ths place at conductor layer 7 height, its position in the present embodiment in 8 li each conductor layers 7; First seals 1/2nd places that the filler strip 5 that respectively insulate in the 2nd, 3,4 conductor layers 7 in 8 is separately positioned on each conductor layer 7 height the inside; Second filler strip 5 that respectively insulate of sealing 8 li is placed on each conductor layer 7 1/3rd and 2/3rds place highly respectively.Change the width or the quantity of insulation filler strip 5, guarantee the evenly closely coiling of each layer conductor, and the height of each conductor layer 7 is equated.The thickness of insulation filler strip 5 equates with the diameter of lead or thickness or is smaller, and is smooth to guarantee each conductor layer 7.For avoiding calculating the dispersiveness of inductance, insulation filler strip 5 should not be too wide.The width of present embodiment insulation filler strip 5 is between 5-35mm.Insulation column 4 is contained in the bottom of coil 1.
Because the utility model is provided with the insulation filler strip in the conductor layer of coil, make the closely coiling of each conductor layer, overcome in the prior art lead rare around the time be difficult to accomplish uniform difficulty, therefore improved coiling manufacturability, eliminated that lead is uneven phenomenon and the flatness that guaranteed every layer conductor; Since lead close around, prevented the mutual displacement of lead of adjacent layer, avoided adjacent layer turn-to-turn current potential too high and improved the dielectric strength of product, and inductance value is comparatively accurate; The close of lead eliminated the air gap that turn-to-turn and interlayer form around simultaneously, stops the discharge that gas causes, thereby improved reliability of operation. Therefore compared with the prior art the utility model has good manufacturability, inductance value is accurate, dielectric strength is high and the operational reliability advantages of higher.
