Key issues in proceeding of intelligent Middle-voltage vacuum circuit breaker

In view of functions related to intelligent control and data collection of middle voltage breaker, the article describes construction and functions of DSP core controller. It is possible to inspect and measure current, voltage, operation positions, working environment and other states of the system on line by designing and developing some key modules, such as Rogowski Coil current transformer, resistance divider voltage transformer,position-sensor, which work together organically for the core control module＇s intelligent analysis, control and protection. Meanwhile,an ideal solution is provided for the middle-voltage vacuum breaker＇s intelligent functioning.
