  1. When switching the no - load overhead lines by alternating - current high - voltage circuit breaker which is a kind of daily operations in electric power system, over - voltage is probably bringed out and insulating property of the electric devices is breakdowned sometimes, especially, when occuring re - strike. the main purposes that the tests on switching line - charging current are performed in the laboratory are assessing re - strike performance of circuit - breakers. according to the test results, the design of the circuit - breaker is optimized and re - strike performance is improved

    交流高壓斷路器是電力系統中最關鍵最重要的設備之一，斷路器開合空載架空線路是電力系統中常見的操作，操作過程中通常會出現過電壓，對系統絕緣造成威脅，嚴重時會破壞系統的絕緣性能，發生事故，隨著電力系統電壓等級的提高、輸電線路不斷延長及傳輸容量的增大，由操作過電壓引起的絕緣閃絡、設備破壞事故的幾率更加突出。
