I-LV Surge Arresters In Action Against Lightning

Ukwenyuka kokuboshwa ngokumelene nombani

Incazelo yokufakwa

Isiza siqukethe amahhovisi (ikhompyutha hardware, ukukhanyisa nokushisa iyunithi), okuthunyelwe kwezokuphepha (i-alamu yomlilo, i-alamu yokugqekeza, ukulawula ukufinyelela, ukubhekwa kwevidiyo) kanye nezakhiwo ezintathu zokwenza inqubo kumahektha ayi-10 Isifunda sase-Avignon saseFrance (amathuba ombani yiziteleka ezi-2 nge-km2 ngonyaka).

I-LV Surge Arresters In Action Against Lightning

Kukhona izihlahla nezakhiwo zensimbi (ama-pylon) eduze kwesiza. Zonke izakhiwo zifakwe abaqhubi bombani. Amandla we-MV ne-LV angaphansi komhlaba.

Izinkinga ohlangane nazo

Isiphepho sishaye isiza, sachitha ukufakwa kwe-LV eposini futhi kwabangela I-36.5 kE yokulahleka kokusebenza. Ukuba khona kwabaqhubi bombani kuvimbele isakhiwo ukuthi singabi nomlilo, kepha okokusebenza kukagesi okwacekelwa phansi akuzange kuvikelwe ngabashushumbisi bokuqhuma, okuphikisana nesincomo kumazinga e-UTE C-15443 ne-IEC 62305.

Ngemuva kokuhlaziya ukufakwa kwamandla nokuqedwa kohlelo lwamandla, kulandelwe ukuqinisekiswa kokufakwa kwabaqhubi bombani nokubheka amanani ama-electrode womhlaba, isinqumo sithathiwe ukufakwa kwabazoboshwa.

Ama-Surge arresters afakwa ekhanda lokufakwa (ibhodi enkulu yokusabalalisa ye-LV) nase-cascade esakhiweni ngasinye sokwenza (bheka isithombe 1 ngenhla). Njengoba uxhumano lwamaphoyinti angathathi hlangothi kwakuyi-TNC, ukuvikelwa kuzonikezwa kuphela ngemodi ejwayelekile (phakathi kwezigaba ne-PEN).

Umdwebo 2 - Ukuboshwa kwamandla kagesi okuphansi

Umdwebo 2 - Uhlobo lwe-SPD 2 no-3 - Ukuvikelwa kwenethiwekhi yamandla okuvuthwa / okudlulayo

  • In (8 / 20µs) kusuka ku-5 kA kuye ku-60 kA
  • Imax (8 / 20µs) kusuka ku-10 kA kuye ku-100 kA
  • Up isuka ku-1 kV iye ku-2,5 kV
  • Uc = 275V, 320V, 385V, 440V, 600V
  • 1P kuye ku-4P, 1 + 1 kuye ku-3 + 1
  • Monoblock futhi pluggable
  • TT, TNS, IT
  • Oxhumana naye oshintshashintshayo ezintantayo

Ngokuhambisana nomhlahlandlela I-UTE C-15443 maqondana nokusebenza phambi kwabaqhubi bombani, izici ze-LSP (Arrester Electric) SPDs SLP40 kanye ne-FLP7 surge arresters zimi kanje:

  • Enhloko yokufakwa
    In = 20 kA, minamax = 50 kA, Up = 1,8 kV
  • Ku-cascade (okungenani i-10 m kude)
    In = 10 kA, minamax = 20 kA, Up = 1,0 kV

E-cascade, ukuvikelwa okuhle kunikezwa amabhodi okusabalalisa wesibili (amahhovisi kanye nokuthunyelwe kwezokuphepha).

Njengoba ukuxhumeka kwephoyinti elingathathi hlangothi kwaguqulwa kwaba yi-TNS, ukuvikelwa kwakudingeka kunikezwe ngemodi efanayo (phakathi kwesigaba ne-PE) nemodi yokuhlukanisa (phakathi kwezigaba nokungathathi hlangothi). Amadivayisi wokunqamula, kuleli cala, angama-breaker wesifunda anamandla okuphula we I-22 kA.

Isifundo // Ukufakwa koMvikeli Wokwanda

Ividiyo ikhombisa ukufakwa okulungile kokuvikelwa kokuqhuma, okuhambisana nokuvikelwa kokusekelayo (okwephula isekethe). I- "Ukuchazwa kwentambo ka-50 cm ”incazelo kuzokusiza ukuthi uqonde ukuxhuma okuqondile ngokuya nge-standard IEC 60364-5-534.
