Abstract
The utility model relates to a novel corona resistant transposition winding wire which comprises an enameled flat wire core, lining paper and an insulating layer, wherein the enameled flat wire core is arranged in a transposition way and is provided with the lining paper in the middle, and the insulating layer is arranged outside the whole of the enameled flat wire core. The novel corona resistant transposition winding wire is characterized in that a corona resistant film layer is arranged between the whole of the enameled flat wire core and the insulating layer. The corona resistant layer is a corona resistant polyamide imide insulating film layer and plays a role of improving the overvoltage resistance and the corona resistance, and an outer layer adopts electrical insulating paper or other insulating materials to carry out multi-layer continuous winding according to the requirements of voltage grades. The corona resistant polyamide imide insulating film layer is made of a material with more favorably thermal stability, improves the resistance of the insulating layer on local discharge degradation, is beneficial to diffusing charge accumulation, can rapidly dissipate heat, effectively play roles of high-frequency pulse voltage resistance and corona resistance, can reduce the temperature rise of a transformer and a reactor and achieve safe and reliable performance.
Description
Technical field
The utility model relates to a kind of electromagnetic wire application technology, particularly a kind of novel anti-corona transposition winding wire.
Background technology
At present, around the conductor of band high-tension electricity, can produce very strong electric field.If electric field strength has surpassed band conductor ambient gas or breakdown of Liquid Dielectrics intensity, will make the gas or the ionization of liquid, the serious partial discharge phenomenon that presents.Here it is usually said " corona phenomenon ".This phenomenon generally shows as: under high-tension line and high pressure is defeated, around the converting equipment, often can hear the sound.In the zone that " corona " also often occurs in the uneven electric field and electric field strength is very high.The generation of " corona " will cause the loss of power, and transformer and transmission facility temperature are raise, and also near radio and communication line be caused interference simultaneously, serious may having influence on safe operation defeated, the power transformation circuit.
Therefore, providing a kind of novel anti-corona transposition winding wire simple in structure, reasonable in design, safe in utilization, is one of these those skilled in the art problem that should address.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of novel anti-corona transposition winding wire simple in structure, reasonable in design, safe in utilization is provided.
The technical scheme that the utility model adopted is for achieving the above object: a kind of novel anti-corona transposition winding wire comprises: enameled sheet wire core, lining paper, insulating barrier; Described enameled sheet wire core transposition is provided with, and the centre is provided with lining paper, and the described enameled sheet wire core integral body outside is provided with insulating barrier; It is characterized in that: be provided with the corona-resistant film layer between described enameled sheet wire core integral body and the insulating barrier.
Described corona-resistant film layer is the polyamidoimide of anti-a corona insulating thin layer.
The beneficial effects of the utility model are: novel anti-corona transposition winding wire not only has whole premium properties of transposed conductor, also set up the layer of anti-the corona, make it have the usefulness that anti-corona, anti overvoltage impact, reduce " electromagnetic pollution " environment-friendly and further energy savings.Because nm inorganic compound is incorporated in the insulating material, increased the resistance of insulating barrier to the partial discharge degraded, and this nano-inorganic substance is thermally-stabilised material preferably, it helps the diffusion charge accumulation dielectric heat of dissipation rapidly itself, play the effect of the anti-corona of anti-high-frequency pulse voltage effectively, can reduce transformer and reactor temperature rise.The utility model architecture is simple, and is reasonable in design, safe in utilization, is widely used.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1 enameled sheet wire core, 2 lining papers, 3 corona-resistant film layers, 4 insulating barriers.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
As shown in Figure 1, a kind of novel anti-corona transposition winding wire comprises: enameled sheet wire core 1, lining paper 2, insulating barrier 4; Described enameled sheet wire core 1 transposition is provided with, and the centre is provided with lining paper 2, and the described enameled sheet wire core 1 whole outside is provided with insulating barrier 4; It is characterized in that: be provided with corona-resistant film layer 3. between described enameled sheet wire core 1 integral body and the insulating barrier 4
Described corona-resistant film layer 3 is the polyamidoimide of anti-a corona insulating thin layer.
In the enforcement (below be of a size of nominal size): with 4.75mm * 1.32mm * 15 piece is example, adopts 4.89mm * 1.48mm enameled sheet wire core (single enamelled wire); Forming profile through transposition is 11.92mm * 9.78mm core (not coating the enamelled wire integral body of any insulating barrier after the transposition), middle lining is with the wide lining paper of 10mm, the layer of anti-corona the in the wrapped nano material of this core external spiral, be the polyamidoimide of anti-corona insulating thin layer, overall dimension is 11.98 * 9.84mm; Outside the layer of anti-the corona, be provided with the insulating material spiral and coat formed insulating barrier, form the finished product transposed conductor of overall dimension 13.57mm * 11.29mm.Particularly between enameled sheet wire core and insulating barrier, be provided with the polyamidoimide of anti-corona corona-resistant film layer, play and improve anti overvoltage ability and anti-corona effect, and then it is outer with electrician's insulating paper or other insulating material, it is wrapped continuously to carry out multilayer by the electric pressure requirement, because nm inorganic compound is incorporated in the insulating material, increased the resistance of insulating barrier to the partial discharge degraded, and this nano-inorganic substance is thermally-stabilised material preferably, help diffusion charge accumulation heat dissipation rapidly, play the effect of the anti-corona of anti-high-frequency pulse voltage effectively, can reduce transformer and reactor temperature rise.
Above-mentioned with reference to embodiment to the detailed description that this novel anti-corona transposition winding wire carries out, be illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection range of the present utility model.
