About motor insulation
Breakdown strength of insulating materials
1. Thermal breakdown. Under the action of an alternating electric field, heat is generated inside the insulating material due to dielectric loss. If it cannot be dissipated in time, the temperature inside the material will rise, leading to breakdown of the molecular structure and breakdown, which is called thermal breakdown. The thermal breakdown voltage decreases with the increase of the surrounding medium temperature, the material thickness increases, the heat dissipation conditions become worse, and the breakdown strength decreases; when the frequency increases, the dielectric loss increases, and the breakdown strength also decreases.
2. Discharge breakdown. Under the action of a strong electric field, the bubbles contained in the insulating material are discharged due to ionization; the impurities are also vaporized by the electric field heating, resulting in bubbles, so that the bubble discharge further develops, leading to the breakdown of the entire material, which is called discharge breakdown.
The breakdown of insulating materials often occurs in the above two forms at the same time, and it is difficult to separate them completely. Impregnating insulating materials with insulating varnish or glue can not only improve the electric field distribution and increase the electrical breakdown strength, but also improve the heat dissipation conditions and increase the thermal breakdown strength.
