Abstract
The utility model relates to the technical field of enamelled wire, in particular to a variable frequency electromagnetic wire which comprises a metal wire core, the outer wall of which is coated with an AI paint layer. As the AI paint is coated outside the metal wire core, the variable frequency electromagnetic wire can avoid the electric discharge phenomena and heating problem of an insulating medium, effectively ensures a variable frequency motor to operate safely, and prolongs the service life of the motor.
Description
Technical field:
The utility model relates to the enamelled wire technical field, particularly the variable-frequency electromagnetic line.
Background technology:
At present, motor adopts variable frequency power supply, and its output voltage waveforms parameter is subjected to the influence of output to motor input factors such as " connection length ".Igbt Inverter Application particularly, input at motor can produce extra-pulse voltage and " upper punch ", be actually and be applied on the motor stator winding, cause partial discharge phenomenon and dielectric heating phenomena between adjacent winding enamelled wire gap, and then cause motor to burn out or shorted-turn fault.Variable-frequency motor in the process of using, exists partial discharge and dielectric heating problems between adjacent winding wire gap with electromagnetic wire, causes easily to burn out, and the useful life of motor is short.
The utility model content:
The purpose of this utility model is to provide the variable-frequency electromagnetic line at the deficiencies in the prior art, it can avoid partial discharge phenomenon and dielectric heating problems between adjacent winding space, can effectively ensure the safe operation of variable-frequency motor, prolong the useful life of motor.
For achieving the above object, the utility model adopts following technical scheme:
It comprises the metal core, and the outer wall of metal core is coated with AI (polyamidoimide) enamelled coating.
The outer wall of described metal core is coated with the frequency conversion enamelled coating, and the AI enamelled coating is coated on outside the frequency conversion enamelled coating.
Described metal core is a copper core.
The beneficial effects of the utility model are, by apply the AI lacquer outside the metal core, can avoid electric discharge phenomena and dielectric heating problems, can effectively ensure the safe operation of variable-frequency motor, prolong the useful life of motor.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a schematic cross-section of the present utility model
Wherein, corresponding label and title are:
1---the metal core, 2---the AI enamelled coating, 3---the frequency conversion enamelled coating.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
See accompanying drawing 1,2, the utility model comprises: metal core 1, wherein, described metal core 1 is a copper core, and the outer wall of metal core 1 is coated with AI enamelled coating 2, behind the coating AI lacquer, can effectively improve the thermal level and the correlated performance of enamelled wire product, make properties of product that certain nargin be arranged.
The outer wall of described metal core 1 is coated with frequency conversion enamelled coating 3, and AI enamelled coating 2 is coated on outside the frequency conversion enamelled coating 3,
The priming paint of the utility model metal core 1 is coated with the frequency conversion lacquer, guarantees that properties of product meet instructions for use, and surface layer is coated with the AI lacquer, improves the thermal level and the performance of product.
The utility model can be avoided partial discharge phenomenon and the dielectric heating problems between adjacent winding space, can prolong the useful life of motor.
The variable-frequency electromagnetic line of employing said structure can adapt to the environment for use of variable-frequency motor, has improved to use and has received the order, and has reduced use cost; There is essential difference in the variable-frequency electromagnetic line with paint vehicle and ordinary lines, can add the nano level metal material in the frequency conversion lacquer to improve, to adapt to " discharge " phenomenon.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
