  1. A change in the power status of the computer is detected, such as a switch from battery power to a c

    檢測到計算機電源狀態的更改,如從電池電源切換到交流電源。
  2. Because of forecasting reactive load at first, it can detect the change of voltage at low - voltage bus from the change of reactive load or the change of voltage at high - voltage bus, then it can decide that adjusting transformer tap or capacitor switch, and avoid blindly and deficient adjusting. on the condition the reactive power is balanced and voltage qualified, it can realize the switching times of loaded taps and capacitors being efficiently decreased

    由於預先預測出無功負荷,提前了解了無功功率變化的趨勢,可以有助於判定低壓母線電壓變化是由無功負荷變化引起還是由高壓側電壓變化引起,從而適時決定是調有載調壓變壓器分接頭還是投切電容器,以此避免了盲目和不充分的調節,實現在保證無功基本平衡和電壓合格率的前提下,減少有載調壓變壓器分接頭的調節和並聯電容器組的投切次數。
  3. By the development of high frequency switch, low frequency transformer has been withdrawn from many domains. but in the domain of ups, linear power amplifier and the inverter output low frequency ac, for the purpose of isolation and change voltage, there is no choice but to use low frequency transformer

    高頻開關技術的發展,使工頻變壓器從許多領域中退了出來,但是在需要隔離的ups不間斷電源、數碼線性功率放大器、要求輸出低頻正弦波的dc ac變換器等許多領域中,為了隔離或變換電壓的需要,以至不得不保留了低頻變壓器。
