Abstract
The invention discloses a manufacturing process of a binding type iron core cake for a dry type iron core reactor, comprising the procedures of piling up, binding, impregnating, high-temperature curing, surface treatment and the like of the iron core cake. The manufacturing process improves the quality of the iron core cake, simplifies the steps, saves the labor cost and simultaneously betters the appearance quality of the iron core cake. The iron core cake manufactured by the process overcomes the phenomenon that the outer silicon sheets of the traditional iron core cakes tilt in the process of pull screw tensioning, reduces the noises of the dry type iron core reactor in the running process after being used on the reactor and has technical indexes superior to the technical indexes of the reactors manufactured by the traditional pull screw fastening process.
Description
Technical field
The present invention relates to a kind of manufacture craft of the cake unshakable in one's determination that in dry-type iron-core reactor, uses.
Background technology
Dry-type iron-core reactor is that winding is the compound inslation medium by resin compounded insulating material castable, with the air, is flux circuit with the iron core and the iron yoke that contain non-magnetic gap that discus and gap, iron yoke and winding are the chief components of dry-type iron-core reactor.The iron-core reactor structure of band gap is because the relative permeability of core portion is higher than the magnetic permeability of the compound inslation of resin and air far away; The magnetic resistance of magnetic circuit nearly all is made up of gap portion, and promptly the size of magnetic resistance depends primarily on the length in gap, and the nonmagnetic substance between discus adopts the epoxy glass fabric panel material of disk shape high rigidity, different-thickness; Thickness is generally several millimeters; Under electrodynamic action, for guaranteeing unshakable in one's determination in running, do not vibrate and misplace, the screw rod bolt fastening structure is drawn in traditional cake employing unshakable in one's determination; The easy perk of tension back both sides silicon steel sheet unshakable in one's determination, and in manufacturing process, have following shortcoming:
1, processing technology is complicated: increase silicon steel sheet punching operation, silicon steel sheet closed assembly after the punching is difficult to guarantee cake end face unshakable in one's determination.
2, production efficiency is low: all silicon steel sheet thickness 0.3mm of cake unshakable in one's determination, and quantity is big, needs the time longer during the silicon steel sheet punch work,
3, cost is higher: tap operation needs special-purpose tapping equipment, mould etc., while labor manpower, and production cost and human cost are higher.
4, behind the punching silicon steel sheet closed assembly with drawing screw rod to clamp, need add insulation between screw rod and the silicon steel sheet, the product long-play, ageing of insulation is prone to cause cake short-circuit conditions unshakable in one's determination to take place.
Summary of the invention
For solve the problems referred to above that traditional cake unshakable in one's determination exists in manufacture craft, the invention provides a kind of manufacture craft of binding type iron core cake for dry type iron core reactor, its technical scheme of taking is:
The processing step of making this iron core cake is following:
(1) will have a plurality of silicon steel sheets of same widths and different length and thickness, and be positioned at same vertical plane according to long limit, broadside is stacked around conglobate mode, forms that to keep flat highly be the column type iron core cake of 50～100cm;
(2) do not have the latitude band along the centre position colligation of silicon steel sheet broadside cake unshakable in one's determination with glass fiber, the glass fiber of institute's colligation does not have the latitude tape thickness and accounts for cake unshakable in one's determination and keep flat 10%～25% of height;
(3) with epoxy resin E-51, curing agent methyl tetrahydro phthalic anhydride and altax P-30 be 100: 85: 0.5 ratio preparation epoxide-resin glue according to mass ratio;
(4) put into the glue pond after earlier the epoxide-resin glue for preparing being heated to 40～60 ℃, put into the glue pond after then the cake unshakable in one's determination after the colligation being heated to 80 ℃, make cake unshakable in one's determination impregnation 10 minutes in epoxide-resin glue;
(5) cake unshakable in one's determination behind the impregnation is put into the high temperature oven hot setting, solidified 2 hours at 100 ℃ earlier, solidified 3 hours at 120 ℃ then, treat to take out when temperature is reduced to below 40 ℃ in the baking oven cake unshakable in one's determination;
(6) promptly get binding-type cake unshakable in one's determination after the circular end surface of the cake unshakable in one's determination after will solidifying polishes flat.
This manufacture craft adopts glass fiber not have latitude band colligation cake unshakable in one's determination; The epoxide-resin glue that adopts preparation is to cake impregnation unshakable in one's determination; And, make smooth the tightening together of each silicon steel sheet to cake hot setting unshakable in one's determination, overcome the phenomenon of traditional cake unshakable in one's determination outside silicon steel sheet perk in the process of drawing the screw rod tension; Improve the fabricating quality of cake unshakable in one's determination, reduce the noise of reactor in running.
The invention has the beneficial effects as follows: the product quality that has improved cake unshakable in one's determination; Simplified processing step; Practiced thrift labour cost; Improved the presentation quality of cake unshakable in one's determination simultaneously, the cake unshakable in one's determination of pressing the making of this kind technology is after using on the dry-type iron-core reactor, and each item technical indicator all is superior to drawing according to tradition the reactor of the fastening technology making of screw rod.
