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(tǒng)中最關(guān)鍵最重要的設(shè)備之一，斷路器開(kāi)合空載架空線路是電力系統(tǒng)中常見(jiàn)的操作，操作過(guò)程中通常會(huì)出現(xiàn)過(guò)電壓，對(duì)系統(tǒng)絕緣造成威脅，嚴(yán)重時(shí)會(huì)破壞系統(tǒng)的絕緣性能，發(fā)生事故，隨著電力系統(tǒng)電壓等級(jí)的提高、輸電線路不斷延長(zhǎng)及傳輸容量的增大，由操作過(guò)電壓引起的絕緣閃絡(luò)、設(shè)備破壞事故的幾率更加突出。
For the circuit - breakers of rated voltage 252kv up , the synthetic test methods are introduced according now condition because of the limitation of the transformer short - circuit capacity . the correlative prescribes on switching line - charging current in gb / t1984 - 200x " alternating - current high - voltage circuit - breaker " are discussed according to the test results and theoretic analysis
由于開(kāi)合空載架空線路試驗(yàn)對(duì)電源側(cè)的阻抗有明確的規(guī)定，這就要求試驗(yàn)電源必須具有足夠大的短路容量，實(shí)驗(yàn)室很難滿足要求，因此，一般對(duì)較高電壓等級(jí)的斷路器采用合成試驗(yàn)方法，本文介紹了利用現(xiàn)有條件，對(duì)252kv以上電壓等級(jí)的斷路器采用合成試驗(yàn)時(shí)的試驗(yàn)線路。
