Description
Technical field
The present invention relates to a kind of employing mutually insulated copper sheet coil and replace traditional wire envelope curve circle; And simple in structure, easily manufactured, wind cooling temperature lowering is effective; Can increase simultaneously the high-capacity reactor that constitutes by multilayer mutually insulated copper sheet of inductance value and capacity again effectively, belong to reactor manufacturing field.
Background technology
Existing high-capacity reactor is on structural design, and principle is to rely on the induction reactance of coil to hinder the electrical equipment that electric current changes.Can be divided into 7 kinds by purposes: the ⑴ current limiting reactor: be series in the power circuit, with the numerical value of limiting short-circuit current.⑵ shunt reactor: generally be connected between the end and ground of ultra high-tension transmission line, play inactive power compensation.⑶ the reactor of communicating by letter is claimed trap again: be connected in the transmission line that the double as communication line uses, in order to stop carrier signal, make it to get into receiving equipment.⑷ arc-suppression reactor; Claim arc suppression coil again: be connected between the neutral point and ground of three-phase transformer; In order to supply with inductive current when the phase ground connection of three phase network; Cross the capacitive current of earth point with flow compensated, make electric arc be difficult for ignition, thereby eliminate because the overvoltage that electric arc is repeatedly restriked and caused.⑸ filter reactor: be used for the amplitude that rectification circuit reduces ripple on the direct current; Also can constitute the circuit that resonance can take place certain frequency, to eliminate the voltage or the electric current of power circuit subharmonic with capacitor.⑹ electric furnace reactor: connect with furnace transformer, limit its short circuit current.⑺ starting reactor:, limit its starting current with motor in series.Its weak point is: the one, because big reactor is when work, coil heating can produce great amount of heat, directly influences the operating efficiency of reactor, and in order to reach the purpose of cooling, people think most variety of way, like water-cooled, air-cooled etc., the one, power capacity is limited; The 2nd, manufacturing cost is high, takes a lot of work, time-consuming.
Summary of the invention
Purpose of design: avoid the weak point in the background technology; Design a kind of employing mutually insulated copper sheet coil and replace traditional wire envelope curve circle; And it is simple in structure; Easily manufactured, air cooling effect is good, can increase simultaneously the high-capacity reactor and the manufacture method that are made up of many circles multilayer mutually insulated copper sheet of inductance value again effectively.
Design: in order to realize above-mentioned purpose of design.Coil was made up of many circles multilayer mutually insulated copper sheet wound core during coiling was wrapped in the reactor; And being equipped with many isolated insulation bars between mutually insulated copper sheet insulated from each other and multilayer mutually insulated copper sheet and forming the design of cooling air passage, is major technique characteristic of the present invention.The purpose of doing like this is: reactor is the long-term normally time of operation under nominal load, be exactly the useful life of reactor, and reactor is determined by the material of making it useful life, and the material of making reactor has metal material and insulating material two big classes.Metal material is high temperature resistant; And insulating material is for a long time under higher temperature, electric field and the action of a magnetic field; Can lose original mechanical property and insulation property gradually, for example become fragile, mechanical strength weakens, electrical breakdown etc., the process of this gradual change is exactly the aging of insulating material.Temperature is higher, and the mechanical property of insulating material and insulation property weaken soon more; Insulating material contains moisture the more, and is aging also faster.Insulating material in the reactor will bear the load of reactor operation generation and the effect of surrounding environment, determines the summation of these loads, intensity and action time the useful life of insulating material.The application adopts the mutually insulated copper sheet to replace conventional coil; The ability and the reactor inductance of loaded current have not only greatly been improved; And greatly prolonged useful life of line bag, and the more important thing is that it and the isolated insulation bar that is erected at have therebetween constituted the air channel that the mutually insulated copper sheet is cooled off fully, the formation in this air channel is the working temperature of control line bag artificially; Both avoided losing of original mechanical property of isolated insulation bar and insulation property; Make the work of reactor be in best operating state again, simultaneously, manufacture craft is simple.
Technical scheme 1: a kind of high-capacity reactor that constitutes by many circles multilayer mutually insulated copper sheet; It comprises reactor; Coil was made up of multilayer mutually insulated copper sheet during coiling was wrapped in the said reactor, was equipped with many isolated insulation bars between mutually insulated copper sheet and mutually insulated copper sheet.
Technical scheme 2: a kind of manufacture method of the high-capacity reactor that constitutes by multilayer mutually insulated copper sheet; It comprises reactor; Coiling is wrapped by multilayer mutually insulated copper sheet around constituting in the said reactor; Vertically be equipped with many isolated insulation bars between multilayer mutually insulated copper sheet and multilayer mutually insulated copper sheet; And the isolated insulation bar that many isolated insulation bars between multilayer are adjacent multilayer is interspersed, thereby constitutes many mutually insulated copper sheet cooling air channels, and a plurality of cold wind exhaust outlets are relative on many mutually insulated copper sheet cooling air channel end faces cold wind water conservancy diversion cavate chassis face relative with it; When the cold wind that a plurality of cold wind exhaust outlets blow out passes through many mutually insulated copper sheet cooling air channels in the mutually insulated copper sheet coiling bag; The heat that produces in the mutually insulated copper sheet is taken out of, made the mutually insulated copper sheet be in suitable temperature all the time, make reactor be in the low temperature normal operating conditions.
The present invention compares with background technology, and the one, solve the technical barrier that those skilled in the art do not have solution for a long time, promptly because the difficult problem that the overheated reactor quality that causes of big reactor winding descends, accident takes place frequently; The 2nd, not only greatly reduced manufacturing cost, and the saving of labor, save time, efficient is high; The 3rd, effectively significantly improved and carried the ability of overcurrent and the inductance of reactor.
