고전압 차단기용 디지털 파이로트 액츄에이터 개발 = Development of a Digital Pilot Actuator for High-Voltage Circuit Breaker

다국어 초록 (Multilingual Abstract)

In this paper, the digital pilot actuator with a solenoid for high-voltage circuit breaker was studied. The solenoid is made of a soft magnetic iron bar with a large number of coil windings. when an electric current passes through this, this stationary core becomes the strong magnet used for hydraulic and pneumatic valve of a solenoid operated valve.
For the performance evaluation of the solenoid for high-voltage circuit breaker, electromagnetic characteristics and dynamic characteristics were analyzed. And, the parameters which is related to performance improvement were investigated. From the experiment of a digital pilot actuator, it was confirmed that time constant of a solenoid is 7㎳ and digital pilot actuator is 54㎳.
