摘　　要：目前,我们经常使用的电容器投切开关在实际的运行过程中还存在着很多问题,新型的过零投切开关主要利用的先进技术为微电子技术,同时企业对电路的结构等开展了进一步的优化与调整,从而能够从根本上进一步的提高开关的安全稳定性,使得电容器组能够在开展过零投切的过程中更加的精确与迅速。通过利用循环投切控制,以及利用共分补优化组合的方式,能够使得过零投切过程的工作效率得到进一步的提升,同时也能使得电容器的使用寿命得到进一步的增长,同时低压电网的无功动态补偿变得更加的高效智能。At present, there are still many problems in the actual operation of capacitor switching switches which we often use. The advanced technology used by the new zero-crossing switching switches is microelectronics technology. At the same time, enterprises have further optimized and adjusted the circuit structure, which can fundamentally further improve the safety and stability of the switch, making the capacitor bank more accurate and rapid in the process of zero-crossing switching. Through the use of cyclic switching control and co-compensation optimization combination, the working efficiency of zero-crossing switching process can be further improved,and the service life of capacitors can be further increased. At the same time, reactive power dynamic compensation of low-voltage power grid becomes more efficient and intelligent.
