用途

  HUVT數(shù)顯系列電壓繼電器主要用于繼電保護(hù)線路中，作為欠電壓或過(guò)電壓監(jiān)視的動(dòng)作元件。報(bào)警電壓值可在產(chǎn)品啟動(dòng)后進(jìn)入菜單自行設(shè)備，且每相報(bào)警電壓設(shè)備相互獨(dú)立。輔助電源電壓一經(jīng)饋入，綠色電壓指示燈亮，將被測(cè)電壓和設(shè)定值進(jìn)行比較，若被監(jiān)測(cè)電壓任意一相達(dá)到報(bào)警狀態(tài)，紅色報(bào)警指示燈閃爍提示報(bào)警，若被測(cè)電壓在延時(shí)時(shí)間內(nèi)恢復(fù)，報(bào)警指示燈停止閃爍，輸出繼電器保持復(fù)位狀態(tài)；若超過(guò)設(shè)定的延時(shí)時(shí)間，輸入電壓還未恢復(fù)，輸出繼電器重位。
   當(dāng)發(fā)生報(bào)警助理輸出繼電器復(fù)位后，若所有被測(cè)電壓又恢復(fù)到正常狀態(tài)，此時(shí)紅色報(bào)警指示燈停止閃爍，輸出繼電器復(fù)位。
  多路監(jiān)視顯示：U1燈亮，數(shù)碼管顯示U1端輸入電壓值；U2燈亮，數(shù)碼管顯示U2端輸入電壓值；U3燈亮，數(shù)碼管顯示U3端輸入電壓值；電壓顯示10S自動(dòng)切換一次，也可以手動(dòng)按“↑”和“↓”鍵切換。
