I-FZN25-12D Series Indoor High Voltage Vacuum Load Switch + Fuse Combination Appliance Umfanekiso obonisiweyo

I-FZN25-12D Series Indoor High Voltage Vacuum Load Switch + Isixhobo Sokudibanisa iFuse

Inkcazo emfutshane:

Iswitshi yomthwalo we-AC ephezulu yangaphakathi ye-FN25-12D/T630-20 ye-AC yangaphakathi ene-voltage ephezulu yesigaba sesithathu se-AC 50Hz. Ukufakelwa kwangaphakathi nge-voltage elinganisiweyo ye-12KV. Ifanelekile ukusasazwa kunye nesitishi esingaphantsi kwamashishini emizi-mveliso kunye nemigodi, njengokhuseleko kunye nolawulo lwezixhobo zombane, ukwahlula i-load current, i-closed-loop current, i-transformer engenamthwalo kunye ne-cable charger current. I-FZRN25-12DmD-31.5 uhlobo lwe-AC yangaphakathi ene-voltage ephezulu ye-vacuum load switch indibaniselwano yi-AC 50Hz yesigaba sesithathu, i-voltage elinganisiweyo ye-12KV yesixhobo sangaphakathi, esifanelekileyo kwiiofisi zokusasazwa kwamashishini emizi-mveliso kunye nemigodi kunye nezinye iindawo. Ukulawula umthwalo kunye nokukhusela i-short circuit. Ixhotyiswe nge-ground switch, inokumelana ne-short-circuit current, indlela yokusebenza ingaba yesandla kunye neyombane, ingabizi kakhulu ukufezekisa iimfuno ezintathu zolawulo olukude lwenkqubo yamandla. Iiswitshi zomthwalo zohlobo lwe-FZN25-12D, FZRN25-12D kunye nezixhobo zombane ezidibeneyo zifanelekile kwinethiwekhi yeringi yesigaba sesithathu okanye kwizikhululo zokusasazwa kwamandla esiphelo kunye nezixhobo zombane zoshishino, zokulawula umthwalo kunye nokukhusela isekethe emfutshane kuba indibaniselwano yezixhobo zombane ze-transformers kunye nezinye izixhobo zombane zikhuselekile ngakumbi kune-circuit breakers, zinoqoqosho ngakumbi, zifanelekile ngakumbi kwinethiwekhi yeringi, iiyunithi zombane zemitha ephindwe kabini kunye nezikhululo zohlobo lwebhokisi.
