Description
Technical field
The present invention relates to a kind of mutually insulated copper sheet coil that adopts and replace traditional wire envelope curve circle, and structure is simple, easily manufactured, wind cooling temperature lowering is effective, effectively can increase again the high-capacity reactor be made up of the mutual insulated copper skin of multilayer of inductance value and capacity simultaneously, belong to reactor and manufacture field.
Background technology
Existing high-capacity reactor is in structural design, and principle is the electrical equipment relying on the induction reactance of coil to hinder curent change.7 kinds can be divided into: (1) current limiting reactor: be series in power circuit, with the numerical value of limiting short-circuit current by purposes.(2) shunt reactor: be generally connected between the end of ultra high-tension transmission line and ground, plays inactive power compensation.(3) communicate reactor, also known as trap: be connected on and double as in the transmission line of communication line, in order to stop carrier signal, makes it to enter receiving equipment.(4) arc-suppression reactor, also known as arc suppression coil: be connected between the neutral point of three-phase transformer and ground, in order to the supply inductive current when a phase ground connection of three phase network, to compensate the capacitive current flowing through earth point, make electric arc not easily ignition, thus eliminate because electric arc is repeatedly restriked the overvoltage caused.(5) filter reactor: the amplitude reducing ripple on direct current in rectification circuit; Also can form with capacitor and the circuit that resonates can occur, to eliminate voltage or the electric current of power circuit subharmonic to certain frequency.(6) electric furnace reactor: connect with furnace transformer, limits its short circuit current.(7) starting reactor: with motor in series, limits its starting current.Its weak point is: one be due to large reactor operationally, coil heating can produce a large amount of heats, directly affects the operating efficiency of reactor, and in order to reach the object of cooling, people think various to the greatest extent mode, and as water-cooled, air-cooled etc., one is that power capacity is limited; Two is that manufacturing cost is high, takes a lot of work, time-consuming.
Summary of the invention
Purpose of design: avoid the weak point in background technology, a kind of mutually insulated copper sheet coil that adopts of design replaces traditional wire envelope curve circle, and structure is simple, easily manufactured, air cooling effect is good, effectively can increase again the high-capacity reactor be made up of multiple turn, multiple layer mutually insulated copper sheet and the manufacture method of inductance value simultaneously.
Design: in order to realize above-mentioned purpose of design.In reactor, coiling bag coil is made up of multiple turn, multiple layer mutually insulated copper sheet wound core, and be equipped with many isolated insulation bars between mutually insulated copper sheet insulated from each other and the mutual insulated copper skin of multilayer and form the design of cooling air passage, be technical characteristics of the present invention.The object done like this is: reactor is the long-term normal time run at rated loads, be exactly the useful life of reactor, and reactor determined by the material manufacturing it useful life, and the material manufacturing reactor has metal material and the large class of insulating material two.Metal material is high temperature resistant, and insulating material is for a long time under higher temperature, Electric and magnetic fields effect, original mechanical property and insulation property can be lost gradually, such as, 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 faster; Insulating material moisture content is the more, aging also fast.Insulating material in reactor will bear reactor and run the load and the effect of surrounding environment that produce, the summation of these loads, intensity and determine useful life of insulating material action time.The application adopts mutually insulated copper sheet to replace conventional coil, not only drastically increase ability and the reactor inductance of loaded current, and greatly extend the useful life of line bag, the more important thing is that it and the isolated insulation bar be erected at therebetween constitute the air channel that mutually insulated copper sheet can be made to cool completely, the formation in this air channel can the working temperature of control line bag artificially, both losing of the original mechanical property of isolated insulation bar and insulation property had been avoided, the work of reactor is made again to be in best operating state, meanwhile, manufacture craft is simple.
Technical scheme 1: a kind of high-capacity reactor be made up of multiple turn, multiple layer mutually insulated copper sheet, it comprises reactor, in described reactor, coiling bag coil is made up of the mutual insulated copper skin of multilayer, is 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 be made up of the mutual insulated copper skin of multilayer, it comprises reactor, in described reactor coiling bag by the mutual insulated copper skin of multilayer around forming, many isolated insulation bars are vertically equipped with between multilayer mutual insulated copper skin and the mutual insulated copper skin of multilayer, and the isolated insulation bar that many isolated insulation bars between multilayer are adjacent multilayer is interspersed, thus form many mutually insulated copper sheet cooling air channels, on many mutually insulated copper sheet cooling air channel end faces face, cold wind water conservancy diversion cavate chassis corresponding thereto, multiple cold wind exhaust outlet is relative, when the cold wind of multiple cold wind exhaust outlet blowout passes through many mutually insulated copper sheet cooling air channels in mutually insulated copper sheet coiling bag, the heat produced in mutually insulated copper sheet is taken out of, mutually insulated copper sheet is made to be in suitable temperature all the time, reactor is made to be in low temperature normal operating conditions.
The present invention is compared with background technology, and one is the technical barrier that solution those skilled in the art do not solve for a long time, namely due to a difficult problem for overheated the caused reactor quality decline of large reactor winding, Frequent Accidents; Two is not only significantly reduce manufacturing cost, and saving of labor, save time, efficiency is high; Three is effectively significantly improve the carrying ability of overcurrent and the inductance of reactor.
