永磁真空开关在低压无功补偿装置中的应用

Application of permanent magnet vacuum switch in low-voltage reactive power compensation installation

"十二五"规划以来,为了改善内蒙古地区城市低压电网无功功率补偿不足等问题,提出了一种新型永磁真空开关控制的低压无功补偿装置,该装置由微控制器、投切电容器用永磁真空开关、熔断器、电容器等部件组成。通过DSP控制器从电网采集三相电压、电流等数据,并通过DSP控制器调节配电网各项参数。应用结果表明,该装置能有效调节内蒙古低压电网无功功率补偿不足,改善电能质量,降低能耗等问题,具有较好的实用意义。

Since the ＂12th Five-Year＂ Plan,in order to improve the insufficient reactive power compensation in Inner Mongolia city,a new permanent magnetism vacuum switch control of low voltage reactive compensation device was proposed,including micro controller,and shooting,cut with permanent magnet capacitor vacuum switch,fuse,capacitor,and etc.Through the DSP controller,three-phase voltage,current,and other data were collected from grid,and the parameters of distribution network were adjusted.The application results show that the device can effectively regulate the insufficient low voltage power grid reactive power compensation in Inner Mongolia city,improve the quality of power,and reduce the energy consumption with good practical significance.
