Description
Technical field
The utility model relates to a kind of enamelled wire of frequency control compressor, is a kind of 200 grades of enamelled wires that are applied to high speed winding frequency-changeable compressor stator specifically.
Background technology
At present, the frequency control compressor that adopts in the production application, it all can produce the high-frequency impulse ripple in the course of the work, this pulse wave energy makes the insulation position accelerated ageing of motor and produces corona, insulation paint film to enamelled wire produces destruction, common enamelled wire variable-frequency motor is easy to produce breakdown between adjacent turns, and the life-span of motor reduces significantly.
In addition, variable-frequency motor is used for compressors such as air-conditioning, refrigerator more, and these compressors all contain refrigerants such as R22, R134a, R407C, and these refrigerants have certain corrosivity.Enamelled wire is being if having refrigerant, refrigerator oil, high temperature, high pressure, long-term work under the environment of corrosion is being arranged, and it must have good cold-resistant matchmaker, high temperature resistant, corrosion-resistant, anti-high-tension ability except can anti-corona effects.
Because of enamelled wire is worked under frequency conversion, hyperbaric environment, the macromolecule of its insulation paint film is easy to generate partial ionization, causes the destruction of paint film, quickens the aging of paint film.In the improvement technology, be to improve the anti-corona performance of paint film, in the lacquer based high molecular, add the nano metal compound particles and shield particle, pulse voltage is dispersed dissolves, avoid producing partial ionization and puncture paint film as quantum.
Yet, because anti-corona paint has added the nano metal compound particles, these metallic compound particles mixes with lacquer liquid and the coating in later stage, baking, solidification process in understand and exert an influence the high molecular link strength that insulate, thereby anti-high voltage, the corrosion resistance of the insulating varnish that weakened cause the destruction of cold-producing medium to the insulation paint film easily.
In addition, added the enamelled wire of nano metal compound particles, its sliding property decline is easy to generate in the rotor winding process and breaks, and drawing-down line, scratch line have directly influenced the anti-corona ability of the enamelled wire of anti-corona the, the useful life of reducing enamelled wire.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of anti-corona effects good, can effective cold-resistant matchmaker, wear-resisting, and self-lubricating effect is good, the enamelled wire of the frequency control compressor of long service life.
Goal of the invention of the present utility model is achieved in that a kind of enamelled wire of frequency control compressor, comprise the conduction sandwich layer and be wrapped in the outer enamel-cover coating of conduction sandwich layer, it is characterized in that: described enamel-cover coating is cold-resistant matchmaker's insulating barrier, anti-corona insulating barrier, cold-resistant matchmaker's abrasion-proof insulating layer and the self-lubricating insulated layer that from-inner-to-outer is provided with in turn, on the surface of cold-resistant matchmaker's insulating barrier attached to the conduction sandwich layer.
Described conduction sandwich layer is a copper cash.
Described conduction sandwich layer is an aluminum steel.
Described conductive cores layer cross section is circular.
Described conductive cores layer cross section is a deltiod.
The utility model improves the enamelled wire of frequency control compressor in the prior art, the enamel-cover coating of enamelled wire is made as cold-resistant matchmaker's insulating barrier that from-inner-to-outer is provided with in turn, anti-corona insulating barrier, cold-resistant matchmaker's abrasion-proof insulating layer and self-lubricating insulated layer, make that enamelled wire can be in frequency conversion, work under the hyperbaric environment, has higher anti-corona ability, prevent film aging, also can refrigerant arranged, refrigerator oil, high temperature, high pressure, have under the environment of corrosion, has cold-resistant preferably matchmaker, high temperature resistant, corrosion-resistant, anti-high-tension ability, and, enamelled wire also has good self-lubricating effect, be convenient to the coiling of motor stator, make enamelled wire no matter under what environment, work and all have better comprehensive performance, prolong its useful life greatly.
Description of drawings
Accompanying drawing 1 is the section of structure of the utility model embodiment 1.
Accompanying drawing 2 is the section of structure of the utility model embodiment 2.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to illustrated in figures 1 and 2, the enamelled wire of frequency control compressor of the present utility model, comprise conduction sandwich layer 1 and the enamel-cover coating that is wrapped in outside the conduction sandwich layer 1, wherein, conduction sandwich layer 1 can be copper cash or aluminum steel, and, for electric wire makes things convenient for coiling, conduction sandwich layer 1 cross section can be circle, also can be deltiod.And the utility model is for overcoming the deficiencies in the prior art part, described enamel-cover coating is cold-resistant matchmaker's insulating barrier 2, anti-corona insulating barrier 3, cold-resistant matchmaker's abrasion-proof insulating layer 4 and the self-lubricating insulated layer 5 that from-inner-to-outer is provided with in turn, on the surface of cold-resistant matchmaker's insulating barrier 2 attached to conduction sandwich layer 1.During this time, cold-resistant matchmaker's insulating barrier 2 is interior one deck of enamel-cover coating, it is better by screening characteristics, the preferable material of tack is formulated, be attached directly on the conduction sandwich layer 1, its purpose be solve cold-resistant matchmaker's performance and anti-corona lacquer is poor as the screening characteristics of priming paint, with the bad shortcoming of tack of copper, ratio of its shared whole layer is between 5%～20%; The second layer: anti-corona insulating barrier 3, it guarantees anti-high frequency, anti-corona performance, the shared whole stratum proportion of this layer is between 30%～60%; The 3rd layer: cold-resistant matchmaker's abrasion-proof insulating layer 4, this layer mainly are to strengthen cold-resistant matchmaker, decay resistance, 15%～35% of the shared whole enamel-cover coating of this layer; Outermost layer is self-lubricating insulated layer 5, and it mainly strengthens the self-lubricating property of whole enamel-cover coating, makes its high speed that adapts to compressor coiling.The utility model is by a kind of novel coating structure combination, utilize the different characteristics of different insulative layer self, with its orderly combining, thereby the motor that has effectively solved the frequency control compressor is in high-frequency percussion and have under the environment of refrigerant machine oil of refrigerant, require the difficult problem of enamelled wire good abrasion resistance and lubrification in the anti-high frequency of enamelled wire, anti-corona, cold-resistant matchmaker, corrosion-resistant, high voltage withstanding and high speed coiling process at high temperature, high voltage, compressor that long-term work under the condition of corrosion arranged, prolonged the useful life of enamelled wire.
