Technical field
The utility model is related to electromagnetic wire technical field, more particularly to a kind of latent oil circle electromagnetic wire.
Background technology
Submersible electric machine with oil is a kind of hydrogenerator being arranged in generator and bearing etc. in the seal casinghousing of shaped like light bulbs,
Feature is structure characteristics of compact layout, complexity, with particular/special requirements such as moistureproof leakproofs.Submersible electric machine with oil is used for oil field oil recovery, in high temperature
Lower work.In order to keep internal and external pressure balance, its inside is all immersed in (such as 10 MPas) wet oil of high pressure including winding.
To avoid joint, the multiplex single electromagnetic wire of winding from being passed around repeatedly in motor slot and formed, therefore it is required that its insulating barrier has well
Wearability.Therefore it is required that its insulating barrier has good wearability.Submersible electromagnetic oil line insulating layer in the market is generally adopted
Formed with Kapton coiling.Electromagnetic wire is partly put up wrapped by film, then carries out high temperature sintering, makes fluoro- 46 fusing
Form the integral insulation of continuous sealing.
In the market is widely used that polyimides-F46 justifies electromagnetic wire, is made of around-packing technology, and the technique is to sintering
Temperature control requirement is higher, and easily seam weak spot occurs in wrapped sintering, and complex process, efficiency is relatively low.Additionally, polyamides is sub-
Amine-F46 latent oils justify electromagnetic wire, and under conditions of strong mineral matter erosion is met, seam crossing is easily destroyed, and causes submersible electric machine with oil to damage.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of new latent oil circle electromagnetic wire, in copper conductor outer cladding
The insulation protective jacket that one layer of special expressing technique of use is molded, so as to overcome drawbacks described above.
The utility model is adopted the following technical scheme that：A kind of latent oil justifies electromagnetic wire, including copper conductor and extrusion in copper conductor
Outer insulating jacket layer, the insulating jacket layer include internal layer and outer layer, be evenly distributed between internal layer and outer layer support with
Cavity.The outer surface of insulation protective jacket outer layer is evenly distributed with triangular hill, and the material of insulating jacket layer is polyimides tree
Fat, insulating jacket layer internal layer, insulating jacket layer outer layer are one pultrusions with support.
Good effect of the present utility model is as follows：Insulating jacket layer of the present utility model uses electrical property and mechanical strength more
Height, the polyimide resin of long-term use can make under the conditions of the erosion medium resistances such as phosphorus, acid, alkali, salt, and insulating jacket layer passes through
Special expressing technique production, insulating jacket layer one-shot forming, without splicing overlap.Avoid and produced using around-packing technology
Defect, improve production efficiency and product quality stability.
The inside and outside two-layer of insulating jacket layer point is evenly distributed with support and cavity between internal layer and outer layer.In submersible electric machine with oil work
During work, once outer layer is damaged because some external factor are produced, internal layer still can provide protection to copper conductor, it is ensured that motor continues
Use, on the one hand can reduce the maintenance cost of submersible electric machine with oil, extend the use time of submersible electric machine with oil, improve the production effect of oil field
Rate；On the other hand when being overhauled to submersible electric machine with oil, breakage can be rapidly found, improves maintenance efficiency, reduce operating personnel
Labour intensity.Under some requirements occasion less high, outer layer is damaged, and the intact electromagnetic wire of internal layer can be continuing with, enter
The production cost of one step reduction enterprise, improves the utilization rate that latent oil justifies electromagnetic wire.
Equally distributed cavity and support between insulating jacket layer internal layer and outer layer.This structure can improve insulation shield
The mechanical strength of jacket layer, because the presence of cavity, when being wound to rotor, winding extruding, cavity mutually between electromagnetic wire
Be under pressure volume-diminished, it is possible to reduce the gap between electromagnetic wire, and the air in cavity for being compressed can be applied to cavity outer wall
Plus a reverse active force, make the even closer of electromagnetic wire winding.Equally distributed cavity is in, latent oil electricity between ectonexine
Vibrations can be absorbed during machine rotor work, is reduced because of the generation caused by vibrations situations such as electromagnetic wire abrasion, breakage.
In the equally distributed triangular hill in the outer surface of insulating jacket layer outer layer, the utility model can be further improved
Tensile property, and the usage amount of material can be reduced, reduce production cost.Outermost layer of the present utility model is complex abrasion-proof
Layer, can further improve wearability, reduce the wear rate during winding and use.
