中文摘要：
利用基于永磁操动机构的真空开关,结合以单片机MC 68332为核心的控制器,研制出同步于电网相位信息的可控型同步断路器.该装置采用零交越相位分析算法,可快速、准确地提取电网的相位信息,产生同步跟踪脉冲;当远方控制指令到达时,断路器根据电网的相位信息进行同步动作,以保证真空开关触头能精确地在正确的位置上开、合.最后在试验过程中实测了同步断路器的参数,试验结果表明该装置动作准确、可靠.
英文摘要：
A controllable SCB synchronizing to the phase information of power grid is developed by using vacuum circuit breaker （VCB） with permanent magnet actuator and the controller based on single chip microprocessor MC68332, in which the algorithm of average series for zero-crossover phase difference is adopted, so the phase information of power grid can be extracted rapidly and accurately and synchronous tracking pulses can be procreated; when remote control instructions are received, according to the phase information of power grid the VCB acts synchronously to ensure that the contactors of VCB can be opened or closed in right position, The test parameters of synchronous VCB are measured in the testing, testing results show that the action of the developed equipment is correct and reliable.
