双断口快速真空开关分闸速度对短路电流短燃弧时间开断特性影响
Influence of Opening Speed of Double-break Fast Vacuum Switch on the Interruption Characteritics of Short-circuit Current with Short Arcing Time
摘要
Abstract
Phase-controlled fast interruption technology for short-circuit currents can effectively reduce the arcing time during interruption,thereby enhancing the performance of vacuum circuit breaker.The study of the influence of the opening speed on short circuit current short arcing time of double-break fast vacuum circuti breaker can provide theoretical base for phase-controlled short arcing interruption of the double-break fast vacuum circuit breaker.In this paper,two sets of 12 kV rapid vacuum circuit breakers and the driving control system are adopted in the test,the syn-thetic experimental circuit system for short circuti current arcing interruption of the vacuum circuti breaker is set up to obtain the relationship curve between double break short arcing time and the critical arc extinguishing clearance and the opening speed.The experimental results indicate that both short arcing time of the double-break short circuit current interruption and the critical arx extinguishing clearance show monotonic decrease with the increase of the opening speed.关键词
