I-LV yokuBamba abaSebenzi ngokuSebenza ngokuchasene noMbane

Ukunyuka kokubanjwa ngokuchasene nombane

Inkcazo yofakelo

Indawo ineeofisi (izixhobo zekhompyuter, izibane kunye neyunithi yokufudumeza), iposi yokhuseleko (ialam yomlilo, ialam yokugqekeza, ulawulo lofikelelo, ucupho lwevidiyo) kunye nezakhiwo ezintathu zenkqubo yokwenziwa kweehektare ezili-10. Ummandla waseAvignon waseFrance (amathuba ombane ziimigca ezi-2 ngeekhilomitha2 ngonyaka).

I-LV yokuBamba abaSebenzi ngokuSebenza ngokuchasene noMbane

Kukho imithi kunye nolwakhiwo lwesinyithi (iipylon) kwindawo ekufutshane nesiza. Zonke izakhiwo zixhotyiswe ngabaqhubi bombane. Amandla ombane e-MV kunye ne-LV aphantsi komhlaba.

Iingxaki ekuhlangatyezwane nazo

Isaqhwithi sabetha isiza, sonakalisa ukufakwa kwe-LV kwisithuba sokhuseleko kwaye sabangela I-36.5 kE yelahleko yokusebenza. Ubukho babaqhubi bombane babuthintele ubume ekubambeni umlilo, kodwa izixhobo zombane ezatshatyalaliswayo zazingakhuselwanga ngababanjiweyo, ngokuchasene nengcebiso kwimigangatho ye-UTE C-15443 kunye ne-IEC 62305.

Emva kokuhlalutya ubuxhakaxhaka kunye nokuqhekeka kwenkqubo yamandla, kulandelwe kukuqinisekiswa kofakelo lwabaqhubi bombane kunye nokujonga amaxabiso e-electrode zomhlaba, isigqibo sathatyathwa ukuze kufakwe ababanjiweyo.

Ukufakwa kokubanjwa kufakelwe kwintloko yofakelo (ibhodi yokuhambisa i-LV ephambili) nakwindawo ekwisakhiwo ngasinye sokwenza (jonga umfanekiso 1 ngentla). Njengoko unxibelelwano lwendawo engathathi hlangothi yayiyi-TNC, ukhuseleko lwaluya kubonelelwa kuphela kwimowudi eqhelekileyo (phakathi kwezigaba kunye nePEN).

Umzobo 2 -Uhlobo lwe-SPD 2 kunye no-3 -Ukonyuka / okwexeshana ukhuseleko kumbane wenethiwekhi

  • In (8 / 20s) ukusuka kwi-5 kA ukuya kwi-60 kA
  • Imax (8 / 20s) ukusuka kwi-10 kA ukuya kwi-100 kA
  • Up ukusuka kwi-1 kV ukuya kwi-2,5 kV
  • Uc = 275V, 320V, 385V, 440V, 600V
  • 1P ukuya ku-4P, 1 + 1 ukuya ku-3 + 1
  • Monoblock kwaye pluggable
  • I-TT, TNS, IT
  • Umdibaniso wotshintsho oludadayo

Ngokuhambelana nesikhokelo UTE C-15443 ngokubhekisele ekusebenzeni phambi kwabaqhubi bombane, iimpawu ze-LSP (Arrester Electric) i-SPDs SLP40 kunye ne-FLP7 yokubanjwa kwabantu abalandelayo zezi zilandelayo:

  • Kwintloko yofakelo
    In = 20 kA, mnamax = 50 kA, Up = 1,8 kV
  • Kwicascade (ubuncinci i-10 m ukuqelelana)
    In = 10 kA, mnamax = 20 kA, Up = 1,0 kV

Kwi-cascade, ukhuseleko olufanelekileyo lunikezelwa kwiibhodi zokuhambisa eziziisekondari (iiofisi kunye neposi yokhuseleko).

Njengoko unxibelelwano lwendawo engathathi hlangothi yaguqulwa yenziwa i-TNS, ukhuseleko kuye kwafuneka lubonelelwe kwimodi eqhelekileyo (phakathi kwesigaba kunye ne-PE) kunye nemo yokwahlula (phakathi kwezigaba nokungathathi hlangothi). Izixhobo zokuqhawula unxibelelwano, kulo mzekelo, zizaphuli zesekethe ezinesakhono sokuqhekeka 22 kA.

Isifundo // Ukufakwa koMkhuseli weSave

Ividiyo ibonisa ufakelo oluchanekileyo lokukhuselwa kokudibana, okunxulunyaniswa nokhuseleko lokugcina (umaphuli wesekethe). Inkqubo ye- "Umgaqo we-50 cm wiring ”inkcazo izakunceda uqonde i-wiring echanekileyo ngokokumiselweyo komgangatho we-IEC 60364-5-534.
