Traditional contactors product-oriented design methods, using trial and error methods

DC contactors as an automatic control of electrical, mechanical, electrical industry, an important basic element in the national economy plays an irreplaceable  mcb circuit breaker  role. High-power DC contactor design a collection of mechanical, electrical, magnetic, thermal and other multi-disciplinary theories,  Voltage stabilizer  difficult. Traditional contactors product-oriented design methods, using trial and error methods, development and production cycle is long, low efficiency, high cost; and product performance and other aspects of electrical life is often difficult to achieve the desired. The dynamic characteristics affecting the merits of high-power DC contactors and electrical life good or bad performance, mechanical longevity is an important factor.
