有载抽头变换器
摘要：
一种有载抽头变换器开关机构(200)，包括：环形凸轮(210)，其限定多个凸起部(311)以及开关组件(220)，其至少部分地布置在环形凸轮内并相对于该环形凸轮旋转，该开关组件包括电开关(224a)和与环形凸轮的内表面接合的凸轮从动件(222a)，其中多个凸起部配置为能够在环形凸轮与开关组件相对旋转时致动该凸轮从动件，该对凸轮从动件的致动引起电开关的操作。
摘要（英）：

An on-load tap-changer switching mechanism (200) comprising: an annular cam (210) defining a plurality of raised portions (311); and a switch assembly (220) disposed at least partly within and rotatable relative to the annular cam, the switch assembly including an electrical switch (224a) and a cam follower (222a) engaged with the inner surface of the annular cam, wherein the plurality of raised portions are configured to actuate the cam follower on relative rotation of the annular cam and switch assembly, actuation of the cam follower causing operation of the electrical switch.
