Frequency conversion enameled wire, also known as corona resistant enameled magnet wire, corona-resistant enameled wire, as its name implies, is able to withstand corona and extend the service life of frequency conversion motor, a special enameled wire, mainly widely used in various frequency conversion motors, speed regulation motors, crane motors, elevator motors.
With the development of power electronics technology, frequency conversion speed regulation has been rapidly promoted. Frequency conversion speed regulation has the following characteristics: 1. Energy saving, making motor energy saving about 30-40%. 2. High speed regulation level, simple speed regulation structure, small size and low investment cost. 3. Easy to use, is conducive to control the production process and improve quality. Therefore, the frequency conversion motor has a wide application prospect in mining, metallurgy, electricity, transportation, household appliances, military industry and other fields, and gradually replaces mechanical speed change and DC speed regulation, which is one of the ten high-tech key popularization in China. However, the pulse wave provided by frequency conversion IGBT and PWM speed regulating device has high peak (peak voltage), steep rise time, variable or extremely high frequency, partial discharge and partial dielectric heating etc. which cause serious damage to the insulating film of enameled wire and make the frequency conversion motor easy to use. Interturn breakdown. This greatly shortens the service life of enameled wires, so corona resistant enameled magnet wire must be developed.
How can enameled wires withstand corona? Henan Signi Aluminum has launched a three-coated enameled polyesterimide/polyamide imide wire with shielding layer, which is an organic coating doped with solid metal compounds such as titanium, silicon, antimony and chromium. The composite corona resistant enameled magnet wire with shielding layer has corona resistance. Henan Signi Aluminum has refined organic coatings by nanotechnology, improved adhesion and basically stabilized the mainstream characteristics of corona resistant enameled magnet wire, which are still in use today.
