Description
Technical field
The utility model relates to enamelled wire technical field, refers more particularly to a kind of self-adhering-type enamelled wire of resistance to corona.
Background technology
Along with developing rapidly of variable-frequency control technique, the application of variable-frequency motor is more and more extensive, especially alternating-current variable frequency motor, and when alternating-current variable frequency motor uses, electricity is impulse wave, waveform has towering spike, and has precipitous rise time and high frequency.Conventional variety enamelled wire is used on this alternating current machine, a little less than ability because of the anti-high frequency of this enamelled wire and momentary pulse peak voltage, enamelled wire winding is easy to occur breakdown between adjacent turns phenomenon, has shortened motor useful life, under these circumstances, the enamelled wire of resistance to corona that variable-frequency motor is used is urgently developed.The anti-corona performance of enamelled wire is in the market low, and a little less than stretch-proof performance, useful life is short.
Chinese patent 200720112935.4 discloses a kind of pair of coating electric corona-resistant enamelled wire, formed by miniature circular copper cash, it is characterized in that miniature circular copper cash scribbles the anti-corona layer of one deck outward and makes priming paint, described anti-corona layer priming paint is corona-resistant wire enamel, scribbles one deck polyamidoimide paint outward do finish paint at anti-corona priming paint.It is two layers of japanning that this utility model changes three layers of japanning of traditional enamelled wire, the complete resistance to corona effects that reaches three layers of emerging envelope curve of resistance to corona in performance, and stretch-resistance is good.But the anti-corona performance of this utility model is low, and useful life is short, two coating results of use are not fine.
