When avoltage surge occurs , it activates a circuit breaker in the surge protector , protecting the computer system 電壓浪涌發生時,就會激活浪涌電壓保護器中的斷路器,從而保護計算機系統。
Most microcomputer users buy a surge protector , a device that separates the computer from the power source of the wall outlet 大多數微機用戶購買浪涌電壓保護器,一種將計算機與壁裝電源插座的電源分開的設備。
When the wave wells up the regulation that the voltage is greater than the gas and in charge of , gas in charge of discharge earth connection too high voltage , protect the apparatus systematically 當浪涌電壓大于氣體管的規定時,氣體管會將過高的電壓放電接地,保護系統器材。
At the severalty microseconds twinkling of an eye , well up to the dozens ofth kilovolt of at voltage at waves / rice , bear enormous load of whole systems , may damage the equipment in consequence 在幾微秒的瞬間,浪涌電壓高達幾十千伏/米,整個系統將承受巨大的負載,后果可能損壞設備。
In all interleaving two - transistor forward switches , zero voltage switching can be obtained which can apparently improve the power density . however the isolated boost converters need to resolve two problems 但是隔離boost變換器需要重點解決兩個問題: 1 )減小功率開關關斷時兩端浪涌電壓; 2 )隔離boost變換器的起動。
Among them insulated the insulation resistance testing instrument to adopt the high direct voltage testing method ; the ac insulate testing instrument adopt to the instrument of ac high voltage , and we also designed the protected circuit with excessive current ; the coil insulate testing instrument is adopt surge voltage impact testing method 其中絕緣電阻測試儀采用了直流高電壓測試法;工頻耐壓測試儀采用高壓工頻測試,并設計了過流保護電路;匝間耐壓測試儀采用浪涌電壓測試法,并設計了多路可控硅控制脈沖輸出電路。
