摘要

操作机构是断路器的核心部分,而断路器的优劣直接影响电力系统的安全运行.因为电力系统对断路器分合闸要求的不断提高,为了获得更快更好的分合闸操作,提出了一种新型双线圈并行驱动的永磁高速操作机构.分别对单驱动线圈操作机构和双驱动线圈操作机构的工作原理进行了阐述,应用Ansoft软件,建立了单驱动线圈操作机构和双驱动线圈操作机构的二维仿真模型,并对仿真结果进行了对比分析.实际设计制作了单驱动线圈操作机构和双驱动线圈操作机构的实验样机进行实验研究,仿真和实验结果均表明,双驱动线圈的永磁高速操作机构和单驱动线圈的永磁操作机构相比,具有更快更好的动作性能,从而达到了对单驱动线圈的永磁高速操作机构的一种优化.%Operating mechanism is the main part of breaker,and the quality of breaker will directly influence the safe operation of power system.Because of the continuous improvement requirements of switch,in order to mak this actuator faster and more powerful closing,this paper proposes a double coil parallel driven permanent magnet actuator at a high speed.This paper expounds the working principle of single and double coil parallel driven permanent magnet actuator.It uses Ansoft building model and contrasts test results.In pratice we designed and produced the single and double coil parallel driven permanent magnet actuator for experimental study.The simulation and experiment results show that double coil parallel driven permanent magnet actuator,compared with single coil parallel driven permanent magnet actuator,has a better and faster action performance.Thus,the double coil parallel driven permanent magnet actuator achieves a kind of optimization.
