摘　　要：高压线路在线监测设备的供电问题一直是在线监测技术中的热点话题。基于特制电流互感器的感应取电技术得到普遍的认可,但是大多数的悬浮取电装置存在取电电路过于复杂的问题,复杂的电路设计会对装置的稳定性产生影响。本文提出了一种基于双向可控硅电压控制的简易高压线路取电装置的设计方法,重点介绍了电流互感器二次侧电压控制部分的设计原理与方法。实验验证了该设计的可靠性与实用性,有效地解决了取电电路过于复杂的问题。Power supply of on-line monitoring equipment is always the hot topic of high voltage line monitoring technology.The draw-out power technology based on the special current transformer induction was widely used,but the circuits of most induction draw-out power devices are too complex.Complex circuit design may influence the stability of the device.This paper puts forward a simply and effectively high voltage line draw-out power device design method which is based on triac voltage control.Introduced the design methods and control principles of current transformer secondary side voltage.The experiment results verified the reliability and practical of the design.
