Abstract
The invention discloses a method for winding a secondary winding of a parallel damping arc suppression coil. The secondary winding is divided into two sections, the two sections are wound on two upper yoke core columns of the arc suppression coil respectively by one layer, in the winding process of the secondary winding, the techniques of adding supporting bars, splay binding, insulation reinforcement at the head end and the tail end and the like are adopted, and finally the secondary winding is formed by casting epoxy resin normal-temperature casting materials. The secondary winding has the advantages of being high in mechanical intensity, good in insulating performance, low in loss and low in cost, the production cost and the operation cost of the arc suppression coil are lowered, and the reliability of operation of an arc suppression coil body is improved.
Description
Technical field
The present invention relates to winding method that is a kind of and damping arc suppression coil secondary winding.
Background technology
And damping arc suppression coil needs to play the object suppressing Cascade System resonance, the independent coiling of secondary winding with secondary winding is in parallel with damping resistance, complete and high pressure winding is isolated.In the structure of the secondary winding of individual layer, single hop coiling, add the height of secondary winding, and the length of iron yoke stem stem, the total height of air gap, the height of each iron-cored cake and window height are fixing, decrease the quantity of air gap, while adding the height of each air gap, add the diffraction area of each air gap, cause the more magnetic line of force through high-tension coil thus produce eddy current loss in wire inside.Wire normally directly tightens up with glass tape by present conventional production technology, and with glue at external coating one deck confining bed, bad mechanical strength, easily loosens, thus causes turn-to-turn insulation and to problems such as the insulation of high pressure winding.
Summary of the invention
For solving the problems referred to above that prior art exists, body invention provides winding method that is a kind of and damping arc suppression coil secondary winding, and its concrete operation is as follows:
(1) processing length of upper yoke stem stem is determined: winding upper surface is more than or equal to 50mm apart from upper yoke stem stem lower surface distance, winding lower surface is more than or equal to 20mm apart from upper yoke stem stem lower surface, the number of turn of secondary winding corresponding different according to each capacity and the height of wire gauge calculating secondary winding, determine the length of upper yoke stem stem;
(2) on upper yoke stem stem, the top and bottom of winding are marked with marking pen, below the mark being close to winding lower end, unshakable in one's determination evenly place that 4 diameters are φ 14, ethylene-propylene rubber highly for 10mm is excellent around, be wound around with glass tape and tighten up, on the correspondence position of the winding of mark, use a grid cloth and 2 DMD paper (width wider than the winding upper and lower side of mark go out 10mm) bottoming respectively, to wrap upper yoke stem stem one week, finally tighten up with glass tape, then on the DMD paper of bottoming, mark the top and bottom of winding again with marking pen and play the position of tail head;
(3) secondary winding from lower end starts around, right in 90 ° around place's wire bending of starting to, winding, carry out 1/2 folded insulating wrapping at bending place DMD paper and glass tape;
(4) starting by insulating strength process, from the grid cloth of bottoming with between DMD paper and iron core, along the minimum level of core limb and the step place of time little level, from the bottom up through grid cloth and the DMD paper of bottoming, and the place's of starting glass tape is tightened up, fixes;
(5) coiling wire turn is started, separate with DMD paper between the place of starting and adjacent turn wire, and in winding process, 4 places are circumferentially being fixed to the first circle wire glass tape, fixing glass tape is pressed in below 3 ~ 5 adjacent circle wires, beat wire simultaneously, to the top 3 circle wire of coil, also tighten up with glass tape;
(6) after the number of turn of the complete design of wire coiling, rear-end correspondence position blocks after wire is left certain surplus, is then bent by wire in 90 °, carries out 1/2 folded insulating wrapping, finally fixed by tail end with glass tape at bending place DMD paper and glass tape;
(7) after wire coiling completes, the method of " Eight characters colligation " is adopted with glass tape, from the lower end oblique pull of winding to the upper end of winding, again from the upper end oblique pull of winding to the lower end of winding, repeatedly, secondary winding is closely linked to be an entirety the most at last, and two DMD paper of wrapping again outside wire, tighten up with glass tape;
(8) use the same method again by another section of secondary winding coiling on the other yoke stem stem, this winding around to for left around to;
After (9) two sections of secondary coil coilings complete, with 0.5mm thick epoxy plate, the same iron-cored cake of yoke stem stem, lower yoke stem stem on arc suppression coil are wrapped together, then use epoxy resin normal temperature castable moulding by casting, finally the two ends of two sections of secondary winding are caused on upper clamping piece.
The method is excellent as lower support with support, effectively avoid winding to glide, winding can be fixed in aggregates by " Eight characters colligation ", ensure that its mechanical strength, add the insulating strength of the insulating material such as DMD paper, glass grid cloth, finally with poured with epoxy resin material moulding by casting, ensure that mechanical strength and the insulation property of secondary winding, avoid the Insulation Problems between the circle of secondary winding and circle, between winding and iron core, between winding and high-tension coil.
Have that mechanical strength is high by the secondary winding of the method coiling, good insulation preformance, loss is low, cost is low advantage, while the production cost reducing arc suppression coil and operating cost, improve arc suppression coil body reliability of operation.
