摘要(Abstract)：
分析了变压器有载分接开关CMA9型电动机构的电气工作原理,通过对某35 kV变电所此型电动机构一起典型故障的分析,提出了一些常见故障的现场处理方法,对电动机构的运行维护工作提出了建议。
This paper analyzes the electrical working principles of CMA9 motor-driven mechanism for transformer on-load tap-changer.Through the analysis on a typical fault of this type of mechanism in a 35 kV substation,the on-site treatment methods for some common faults are proposed together with the proposals on the operation and maintenance of the motor-driven mechanism.
