③ 摘要
廣泛應(yīng)用于輸電和供電線路上的有效反事故措施。即當(dāng)線路出現(xiàn)故障，繼電保護(hù)使斷路器跳閘后，自動重合閘裝置經(jīng)短時間間隔后使斷路器重新合上 。大多數(shù)情況下，線路故障（如雷擊、風(fēng)害等）是暫時性的，斷路器跳閘后線路的絕緣性能（絕緣子和空氣間隙）能得到恢復(fù)，再次重合能成功，這就提高了電力系統(tǒng)供電的可靠性。少數(shù)情況屬永久性故障，自動重合閘裝置動作后靠繼電保護(hù)動作再跳開，查明原因，予以排除在送電。一般情況下，線路故障跳閘后重合閘越快，效果越好。重合閘允許的最短間隔時間為0.15～0.5秒 。線路額定電壓越高，絕緣去電離時間越長。自動重合閘的成功率依線路結(jié)構(gòu)、電壓等級、氣象條件、主要故障類型等變化而定。據(jù)中國電力部門統(tǒng)計(jì)，一般可達(dá)60％～90％。用電部門的另一種廣泛應(yīng)用的反事故措施是備用電源自動投入，通常所需時間為0.2～
0.5秒。它所需投資不多而維持正常供電帶來的經(jīng)濟(jì)效益甚大。


Widely used in transmission and distribution lines, the effective anti-accident measures. That is, when the line failure, the relay circuit breaker tripping, the device auto-reclosing after a short time interval, so that a re-breaker. In most cases, fault lines (such as lightning, wind, etc.) is temporary, after tripping circuit breaker insulation performance (insulator and air space) can be restored, coincidence can be successful again, which increased the power supply system reliability. Limited circumstances permanent fault, automatic re-closing devices on the move after the opening relay action Zaitao to identify reasons, be excluded from the power supply. Under normal circumstances, line fault reclosing after tripping sooner, the better. Reclosing allow for the shortest time interval 0.15 to 0.5 seconds. Rated voltage lines higher insulation to the longer ionization time. Automatic reclosing the success rate structure on line, voltage levels, weather conditions, fault type, and other major changes may be. According to statistics of China's power sector, usually ranging from 60% to 90%. Another electricity sector widely used anti-accident measures are automatic standby power input, the time usually required for the 0.2 ~
0.5 seconds. It required little investment in the maintenance of normal supply substantial economic benefits.
