Description
Technical field
The present invention relates to a kind of enamel-covered wire, particularly a kind of corona-resistant lacquered wire for variable-frequency motor.
Background technology
In response to the energy-saving and emission-reduction that country advocates, owing to converter technique has preferable energy-saving effect, therefore obtain big
The development of power.But the high-frequency impulse pressure that existing frequency conversion motor produces is very big, and frequency conversion motor employing at present is common
Enamel-covered wire winding cannot bear high-frequency impulse pressure, causes coiling group the most breakdown, thus shortens the service life of frequency conversion motor,
And enamel-covered wire is for a long time by high-frequency pulse voltage, also can accelerate the aging of insulating barrier, affect the service life of motor.
Summary of the invention
It is an object of the invention to, it is provided that a kind of corona-resistant lacquered wire for variable-frequency motor.It has can bear higher
The feature in the service life of pulsating pressure and prolongation frequency conversion motor.
Technical scheme: a kind of corona-resistant lacquered wire for variable-frequency motor, including copper round wire, sets outside copper round wire successively
There are the first insulating barrier, the second insulating barrier and the 3rd insulating barrier；Described first insulating barrier includes two layers polyester imines enamelled coating, adjacent
Metal-oxide polyester-imide enamelled coating it is provided with between polyester-imide enamelled coating；Described second insulating barrier includes the first shielding enamelled coating, titanium
Metallic shield enamelled coating, silicon metallic shield enamelled coating, antimony metal shielding enamelled coating, chromium metallic shield enamelled coating and secondary shielding enamelled coating；Described
3rd insulating barrier includes two-layer polyamidoimide enamelled coating, is provided with metal-oxide polyamides between adjacent polyamidoimide enamelled coating
Amine acid imide enamelled coating.
In aforesaid a kind of corona-resistant lacquered wire for variable-frequency motor, described first insulating barrier, the second insulating barrier and the 3rd are exhausted
The ratio of the thickness between edge layer three is 1:4:1.
In aforesaid a kind of corona-resistant lacquered wire for variable-frequency motor, described first shielding enamelled coating and secondary shielding enamelled coating set
There is metal oxide nano particles.
Compared with prior art, the present invention passes through at the first insulating barrier metal-oxide polyester-imide enamelled coating, can be to wearing
The high-frequency pulse voltage crossing screen layer shields again, sub-by arranging metal-oxide polyamide acyl in the 3rd insulating barrier
Amine enamelled coating, can be slowed down the high-frequency pulse voltage impact to screen layer, then shielded by the second insulating barrier, by upper
State three kinds of measures and can be effectively improved the corona-resistance property of enamel-covered wire, improve the ability of its anti-high-frequency pulse voltage；By by
The screen layer that two insulating barriers are arranged to be contained different metal by multilamellar forms, and can utilize the shielding of metal to greatest extent
Can, improve its corona-resistance property；It addition, by arranging nano-metal-oxide in the first screen layer and secondary shielding layer
Grain, utilizes metal oxide nano particles with the characteristic of chemical bonds, and formation is that the paint film with metal-oxide has more
Strong corona-resistance property, can play preferably buffering and shielding action, thus extend frequency conversion motor high-frequency pulse voltage
Service life；By arranging above-mentioned paint film so that enamel-covered wire can bear high-frequency pulse voltage, slow down the aging speed of insulating barrier
Degree, extends the service life of frequency conversion motor.In sum, the present invention have can bear higher pulsating pressure and extend become
Frequently the feature in the service life of motor.
