Description
Technical field
The present invention relates to a kind of manufacturing approach of lead, particularly a kind of manufacturing approach of pressing from both sides the screen combined shifting lead.
Background technology
At present; What electric energy transmitting generally used in the power transmission and distribution system is the mode of movement of high-voltage alternating; But the characteristics of China's electrical network are that energy resources and economic development geographical distribution are extremely unbalanced; Must the long distance of development, big capacity electric energy transmission technology, adopt new or higher one-level electric pressure realizes that southwestern water power east is sent with thermoelectricity south, North China and send.Research both at home and abroad at present concentrates on HVDC and ultra-high voltage AC transmission technology.Wherein, high voltage dc transmission technology and ultra-high voltage AC transmission compared with techniques, high voltage dc transmission technology has its special advantage:
1, high voltage direct current transmission is the two poles of the earth DC power transmission line that adopts two-wire system, and high-voltage AC transmission is to adopt three three-wire system transmission lines now; DC power transmission line than transmission line of alternation current province a power transmission line, save power transmission material 1/3 naturally.
2, carry same electric energy, DC power transmission line has lacked single line than the transmission line of alternation current, thus the loss on the line resistance also than ac transmission little 1/3.
3, in the seabed or underground transmission must use cable, and cable line always has the electric capacity of can not ignore, and adds alternating voltage; Capacitance current is just arranged on the circuit; It has reduced the ability to transmit electricity of cable, and uses direct current transportation, though cable has electric capacity; But do not have capacitance current, ability to transmit electricity is than much bigger under the interchange situation.
4, during direct current transportation, the AC system of generating and the AC system of electricity consumption need not synchronous operation, and the AC system at two ends can be by frequency and phase place operation separately; And during ac transmission, the AC system of generating and the AC system of electricity consumption must synchronous operations, and in the AC system of China, the frequency of alternating current is 50 hertz, and each system must be by this Frequency Synchronization operation, otherwise, cause power outage easily, even damage equipment.
5, the two poles of the earth in the DC power transmission line are independent regulation and work, did not influence to each other, therefore, and when a utmost point breaks down, the fault of need only the stopping transport utmost point, another utmost point still can be worked, and the electric energy of just carrying has reduced; And when ac transmission, as long as have one to break down mutually, will all fronts interruption maintenance.
6, but the DC power transmission line built by separate periods puts into operation by stages, builds a utmost point earlier, and constitutes the loop with the earth or seawater, waits to load after the increase, builds another utmost point again.
7, direct current transportation is to the interference of communication equipment and all much little than ac transmission to the pollution of environment.
8, the structure of the transmission of electricity bar on the DC power transmission line, tower is also light and simple than ac transmission bar, tower with capacity, also can improve the job stability of two ends AC system simultaneously.
Must use the high voltage direct current converter device in the high voltage dc transmission technology, i.e. high voltage direct current converter transformer, the special-purpose winding wire that the screen combined shifting lead is applied to the high voltage direct current converter transformer is pressed from both sides in the present invention.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, and a kind of manufacturing approach of pressing from both sides the screen combined shifting lead is provided.
Technical scheme of the present invention is: a kind of manufacturing approach of pressing from both sides the screen combined shifting lead, and this folder screen combined shifting lead comprises copper strap wire, paint film layer, middle lining paper, insulating barrier, shielding conductor, shielding conductor insulating barrier and external insulation layer, its manufacturing approach comprises:
One, the manufacturing of transposed conductor:
A, with wire-drawing equipment the copper bar is drawn and to roll into copper strap wire;
The material of B, paint film layer is 120 grades of acetal paints, outside through the copper strap wire behind the high annealing, coats paint film layer with enamelling machine, processes enameling copper strap wire;
C, many enameling copper strap wires are combined into two row of wide contact; On request on two row enameling copper strap wires with below do the same transposition that turns to along leptoprosopy; Middle lining paper is set in the centre of two row enameling copper strap wires, and is used in the outer lapped insulation layer of two row enameling copper strap wires, process transposed conductor;
Two, the manufacturing of shielding conductor: through extrusion equipment the copper bar is squeezed into shielding conductor, utilizes paper bag equipment wrapped shielding conductor insulating barrier outside shielding conductor then.
Three, two transposed conductor combinations, the shielding conductor of the outer wrapped shielding conductor insulating barrier of therebetween, wrapped again external insulation layer.
The further technical scheme of the present invention is: when outside copper strap wire, coating paint film layer with enamelling machine, be 215～470 ℃ through the stoving temperature in the enamelling machine burner hearth.
The present invention more further technical scheme be: in the enamelling machine burner hearth cure warm area be with the burner hearth height from top to bottom the equispaced be divided into three districts, wherein 1 district: 320 ℃～360 ℃, 2 districts: 430 ℃～470 ℃, 3 districts: 215 ℃～255 ℃.
The present invention has been owing to adopted the structural design of shielding conductor in the combined shifting lead, thereby solved the technical barrier that overvoltage and short circuit influence the DC converter transformer in the prior art, compared with prior art; Have shock-resistant, anti-overvoltage, and characteristics such as anti-short circuit; Prolong the useful life of converter transformer valve coil winding effectively, guaranteed the normal operation of transformer and supply network, reduced power supply cost; And this product simplification the manufacturing process of the complicated loop construction of DC converter transformer; Can improve the manufacturing efficient of coil, can dwindle the transformer size simultaneously, reduce manufacturing cost.
