基于电容式传感器的双投控制装置的研制

摘要

This paper designed an automated control device used for double throw switch switching. In order to meet the power source requirement of control devices in project design plan, in the design plan without a voltage transformer, the device adopted a kind of en-tirely new chopper stable voltage electronic power supply circuit based on the normal current transformer as induction coil. With the help of normal energy storage element, power supply energy met the whole working process of control devices, thus to realize state stability of device working and action reliability, to make automatic transfer switch electrical function of medium voltage power distribution load switch more practical.%　　设计了一款用于双投开关切换的自动控制装置，为满足工程设计方案的控制装置电源需求，在电压互感器被取消的设计方案下，该装置全新采用了一种基于常规电流互感器作为取能线圈的斩波稳压电子电源电路，借助常规储能元件，使得电源能量总能满足控制装置的整个工作过程，从而实现装置工作的状态稳定性和动作可靠性，使得中压配电负荷开关的自动转换开关电器功能更加实用。
