I-YC9VA Voltage Protection Relay
Ukubukeka Nobukhulu Bekhiphedi
Incazelo
I-voltage ye-YC9VA kanye ne-current display relay iyithuluzi lokuqapha i-voltage elisuselwa ku-microprocessor kumanethiwekhi e-AC esigaba esisodwa ukuvikela okokusebenza kukagesi ku-voltage yokuqhuma.Idivayisi ihlaziya i-voltage eyinhloko futhi ibonise inani layo lamanje kusibonisi sedijithali.Umthwalo ushintshwa yi-electromagnetic relay.Umsebenzisi angasetha inani lamanje le-voltage kanye nesikhathi sokulibaziseka ngokusebenzisa inkinobho.
Inani ligcinwa kumemori engaguquki.Izintambo ze-Aluminium nezintambo zethusi zingasetshenziselwa ukuxhuma.
Isicelo
I-voltage ye-YC9VA kanye ne-relay yesibonisi yamanje esetshenziswa ezakhiweni zokuphatha, zezimboni nezindawo zokuhlala futhi inomsebenzi wokuvikela imigqa yesigaba esisodwa:
Ukuvikelwa kwe-undervoltage;
Ukuvikelwa kwe-overvoltage;
Isebenza ngaphansi kwemodi ye-voltmeter.
Imisebenzi yokuSebenza nokufaka
Uma i-voltage isetshenziswa kudivayisi, inkomba yedijithali izobonisa inani lamanje le-voltage kunethiwekhi.
Ukukhanya okukhanyayo kubonisa ukuthi ayikho i-voltage ekuphumeni kwedivayisi.Uma i-voltage yokuhlinzeka ingaphakathi kwebanga elimisiwe, ngemva kwe-Ton (okuzenzakalelayo imizuzwana engu-30), umthwalo uzovuleka futhi inkomba izoyeka ukukhanya.Uma i-voltage ingekho phakathi kwebanga elicacisiwe, umthwalo ngeke uxhunywe kulayini kuze kube yilapho i-voltage ibuyela evamile.Okwamanje, uma i-voltage iphansi kunomkhawulo obekiwe ophansi ngesikhathi sokuqala kabusha, inkomba yephutha izokhanya.Uma i-voltage ingaphezu komkhawulo ongenhla obekiwe, inkomba yephutha izohlala ivuliwe.
1. Faka futhi uvikele i-relay.
2. Xhuma izintambo ku-relay ngokuya ngohlelo.
3. Setha inani le-voltage oyifunayo.
4. Setha isikhathi sokuphendula esidingekayo.
