kilovolt-ampere

Intelligent electricity quantity concentration display instrument is a kind of intelligent instrument used to measure combined parameter of ac electricity quantity , which can simultaneously measure each phase electricity parameter in the tri - phase ac loop such as voltage , current , active power , reactive power , apparent power , power factor , frequency , active kilowatt hour , reactive kilovolt ampere - hour and so on 智能電量集中顯示儀是一種用于交流電量綜合參數測量的智能儀表,它可以同時測量三相交流回路的每一相電壓電流有功功率無功功率視在功率功率因數頻率有功電度無功電度等參數。

Hvdc is an abb innovation that transports large power loads over long distances with low losses and minimal environmental impact , requiring just two 500 kilovolt ( kv ) dc power lines to carry the same power load as five alternating current ( ac ) lines Hvdc技術是abb的一項創新，在長距離的傳輸中，它傳送大量的電量，而損失很低，而且對環境的影響也達到最小化，只需要兩條500千伏的直流電線就可以運載相當于五條交流電線輸送的電量。

The ultrahigh - voltage direct current ( uhvdc ) link comprises two substations and a power transmission system using breakthrough technology to transmit electricity at ultrahigh voltage ( 800 kilovolts ) , which will minimize the amount of power lost in transmission 該超高壓直流輸電( uhvdc )線包括兩個變電站以及一個采用了突破性超高壓（ 800千伏）電力傳輸技術的電力傳輸系統，這將減少傳輸過程中的電力損失。

The 500 - kilovolt electricity transmission line ， extending from fangzheng , mudanjiang , dunhua to baojia , as part of the project of “ electricity transmission from north to south ” of the province ， has been completed and will be put into operation in succession 近日，黑龍江“北電南送” 500千伏方正牡丹江敦化包家輸變電工程的線路架設全部竣工，并即將陸續投入運營。

Abb will replace an existing outdoor 275 kilovolt ( kv ) substation now nearing the end of its service - life with an indoor substation based on compact , state - of - the - art , gas insulated switchgear ( gis ) Abb將用基于體積較小的頂級的氣體絕緣接電開關裝置（ gis ）的室內變電站替換現有的服務年限將到的室外275千伏特的變電站。

At 400 kilovolts , a standard value for long - distance transmission , an alternating current 30 metres ( 100 feet ) from the ground has a fortieth of the loss of a similar cable at ground level 在遠距離傳輸的標準電壓400千伏下，電纜離地30米（ 100英尺）時的電量損耗是同樣電纜在地面時損耗的四十分之一。

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。

Transmission losses will be less than 7 percent , significantly less than the losses from conventional 500 - kilovolt ( kv ) high - voltage direct current ( hvdc ) transmission schemes 電力的傳輸損失將少于7 % ，遠遠低于傳統500千伏高壓直流( hvdc )傳輸計劃的損失量。
