Umvikeli Wamanje We-Transformer Secondary Overvoltage
ububanzi besicelo
Isivikeli sesibili se-overvoltage yamanje ye-transformer sifaneleka kakhulu ukujikajika okuhlukile, ukujika kwe-overcurrent, ukujika kwesilinganiso, ukujika kokuvikela ibhasi kanye nokujika kwesipele kohlangothi lwesibili lwe-CT.Isetshenziselwa ukuvimbela i-overvoltage edlulayo engaphansi komthelela we-overvoltage yezinto zokusebenza kanye nokukhipha amandla okushisa, ukuze kuvikelwe isekethe yesistimu kanye nemishini.
Izimo zesevisi ezijwayelekile nezimo zokufaka
1. Izimo zesevisi ezijwayelekile
a.I-Voltage: Amandla kagesi asetshenziswa ngokuqhubekayo phakathi kwamatheminali avikela amandla kagesi akufanele eqe umkhawulo wawo omkhulu
I-voltage enkulu eqhubekayo yokusebenza.
b.Izinga lokushisa le-ambient: -20℃ ~70℃.
c.Kusetshenziswe umswakamo we-ambient: <95%RH.
d.Izinga lokuvikelwa kwezindlu: IP20.
e.Izinga lokungcola: Izinga lokungcola endaweni yokufaka lisezingeni lesi-2.
2. Izimo zokufaka
a.Isigaba sokufakwa: ngokwezinga lokuvikela i-voltage yedivayisi yokuvikela i-overvoltage ihlukaniswe izigaba ezimbili;
b.isayithi lokufaka:

| indlela yokufaka | Uhlobo lwethrekhi |
1. Kunconyelwe iziza ezingavezwanga kangako;
2. Izofakwa ngaphandle kokudlidliza okubalulekile nomthelela.
3. Indlela yokufaka: sebenzisa isitimela sohlobo lwe-TH35-7.5 ukuze ufakwe.
4. Imodi yocingo: i-wiring yokucindezela isikulufa.
Ukubukeka nosayizi wokufaka
Usayizi uwonke: 115 * 90 * 40 (ubude * ububanzi * ukujula) (CTB-6) iyunithi: mm
