Technical Field
The utility model relates to an enameled round copper wire, especially a 180 level polyester imide enameled round copper wire.
Background
The enameled round copper wire is a round copper enameled wire which is formed by taking a round copper wire as a base material and painting an insulating paint film on the surface of the round copper wire. However, the structure of the currently used enameled wire mainly comprises a metal wire core and a polyester paint layer coated outside the metal wire core, and the enameled wire coating with the structure is a single coating, so that the enameled wire has general heat resistance, and the coil can be heated and burnt out after being used for a long time, and cannot bear higher breakdown voltage, thereby affecting the normal use of the motor. Therefore, the prior art has the problems of poor high temperature resistance and incapability of bearing higher breakdown voltage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a 180 level polyester imine enameled copper round wire. The utility model has the characteristics of can effectively improve high temperature resistance and can bear higher breakdown voltage.
The technical scheme of the utility model: 180 level polyester imide enameled copper round wire, including the copper round wire body, copper round wire body surface is equipped with nylon paint layer in proper order, anti-oxidant protective layer surface is equipped with a set of ring channel, is equipped with nanometer ceramic fiber in the ring channel and pastes the layer, and anti-oxidant protective layer surface is equipped with miscellaneous naphthalene biphenyl polyarylether nitrile ketone coating, jade fibre and pastes layer, polyacetyl acetal resin insulating varnish, aromatic polyimide paint layer and polyester imide paint layer.
In the 180-grade polyesterimide enameled round copper wire, the annular groove comprises an annular groove body, and a group of annular distributed tooth-shaped grooves are formed in two sides of the annular groove body.
In the 180-level polyester imide enameled round copper wire, the thickness ratio of the nylon paint layer, the antioxidant protection layer, the heteronaphthalene biphenyl polyarylether nitrile ketone coating, the jade fiber pasting layer, the polyacetyl acetal resin insulating paint, the aromatic polyimide paint layer and the polyester imide paint layer is 1: 1.5: 1: 0.5: 1: 0.8: 2.
compared with the prior art, the utility model discloses a coating in proper order is in this external nylon paint layer of copper circle line, anti-oxidant protective layer, jade fibre paste layer, miscellaneous naphthalene biphenyl poly aromatic ether nitrile ketone coating, polyacetyl acetal resin insulated paint, aromatic polyimide lacquer layer and the mutually supporting between the polyester imide lacquer layer, rationally optimizes the position of each coating for the enamelled copper flat wire that obtains not only can be able to bear the high temperature of 180 degrees, also has simultaneously and bears higher breakdown voltage. And simultaneously, the utility model discloses still constitute the ring channel through setting up a set ofly by annular groove body and flute profile groove on anti-oxidation protection layer surface to set up nanometer ceramic fiber in the ring channel and paste the layer, can further improve high temperature resistance on the one hand, on the other hand pastes the layer cooperation with jade fibre, and through improving the holistic heat dispersion of enameled wire, further promote the holistic high temperature resistance of enameled wire. Furthermore, the utility model discloses still paste the layer through setting up miscellaneous naphthalene biphenyl polyarylether nitrile ketone coating between anti-oxidant protective layer and jade fibre for the holistic pliability of enameled wire prevents that the paint film from tearing, can also improve the adhesion that layer and jade fibre were pasted to the nanometer ceramic fibre. To sum up, the utility model has the characteristics of can effectively improve high temperature resistance and can bear higher breakdown voltage.
Additionally, the utility model discloses a ring channel comprises annular groove body and flute profile groove, not only can increase area of contact, promotes high temperature resistance, and the nanometer ceramic fibre of still being convenient for simultaneously pastes the installation and the fixed on layer.
