摘要
针对高压交流接触器在电力系统中频繁接通与断开负载回路这一特点,在分析对其触头造成侵蚀的主要因素的基础上,利用电力电子器件的优点,设计出一款新型高压交流接触器控制电路。经计算机虚拟仪器进行全程数字记录表明,该设计达到了预期的效果,提高了接触器的整体效能。
Aim at the characteristic of high-voltage AC contactors which frequently switch load circuit in the power system, based on the analysis of the main factors for contact erosion, combining with the advantages of power electronic device, a brand new high voltage AC contactor controlling circuit is developed. The record of computer virtual instrument indicates that the prospected goal of the research hare achieved and the design is improved the overall effect of the contactnr.
