Ibha ye-HRC yokuhlukanisa iswishi ene-160A yesixhumi se-fuse switch
I-HR17 Fuse-switch Disconnector isetshenziswa ngaphansi kwe-Rated Voltage 690V.Okuyinhloko yamanje yi-160A kuya ku-630A.Isetshenziswa kakhulu njengokushintsha kwamandla, ukushintshwa kwe-isolator kanye nokushintsha okuphuthumayo ohlelweni lwamandla.
Izixhumanisi ze-fuse ezinhlobonhlobo: I-NH00 ye-160A, i-NH1 ye-250A, NH2 ye-400A kanye ne-NH3 ye-630A
Izilinganiso zamanje: 4, 6, 10, 16, 20, 25, 32, 35, 40, 50, 63, 80, 100, 125, 160, 200, 224, 250, 300, 315, 305, 4 kanye ne-630 fuse, fuse switch,
HR17 fuse uhlobo isolation switch, ukalwe insulating voltage AC800V.rated ukusebenza voltaged 690V.I-400V, imvamisa elinganiselwe ngu-50HZ.amanani amanje angu-160A ~ 630A ikakhulukazi asetshenziswa njengokushintsha kwamandla, ukushintshwa okuhlukanisayo kanye nokushintsha kwezimo eziphuthumayo nomsebenzi wokuvikela kusekethe enomjikelezo omfushane omfushane wamanje kanye nesekethe yemoto, le swishi ayisetshenziselwa ukusebenzisa injini eyodwa.
Lapho ummese we-isolator uthatha indawo ye-fuse, le swishi ayinayo isekethe kagesi ukuze ilayishe kakhulu ngamasekethe amafushane umsebenzi wokuvikela, yanelisa kuphela isilinganiso le swishi eshiwo ukuthi izosifaka phakathi nomzuzu wephula i-abilitu, yenza umugqa uhlukanise ukusetshenziswa.
lo mkhiqizo uhambisana ne-GB14048.3-2002.IEC 947-3(1999) ejwayelekile
Imvelo Esebenzayo
1. Izinga lokushisa le-ambient akufanele lidlule +40℃;isilinganiso phakathi kwamahora angu-24 ngeke seqe +35℃;umkhawulo ophansi wezinga lokushisa le-ambient ngu--5℃.
2. Iswishi izofakwa endaweni ephakeme engengaphezu kuka-2,000m.
3. I-RH ezungezile yendawo yokufaka akufanele yeqe u-50% ngaphansi kwezinga lokushisa eliphezulu elingu-+40℃ futhi inani eliphakeme le-RH livunyelwe ngaphansi kwezinga lokushisa eliphansi;isilinganiso sokushisa esiphansi senyanga emanzi kakhulu akumele seqe +25℃ futhi isilinganiso esiphezulu se-RH senyanga akumele sidlule ku-90℃.
4. Iswishi izofakwa endaweni lapho isigaba sayo sokunukubezeka kwemvelo singu-3.
5. Isigaba sokufakwa kweswishi sizoba III.
6. Iswishi izofakwa endaweni ngaphandle kokudlidliza kanye nomthelela.
