LV Akukwera Kumangidwa Potsutsana Ndi Mphezi

Akukonda akumanga motsutsana ndi mphezi

Kufotokozera za kukhazikitsa

Tsambali limakhala ndi maofesi (makina apakompyuta, zowunikira, ndi zotenthetsera), malo achitetezo (alamu yamoto, alamu akuba, kuwongolera mwayi, kuwonera makanema) ndi nyumba zitatu zopangira mahekitala 10 Dera la Avignon ku France (kuthekera kwa mphezi ndikumenya kawiri pamakilomita2 pachaka).

LV Akukwera Kumangidwa Potsutsana Ndi Mphezi

Pali mitengo ndi miyala yazitsulo pafupi ndi tsambalo. Nyumba zonse zimakhala ndi oyendetsa mphezi. MV ndi LV magetsi amapereka mobisa.

Mavuto omwe anakumana nawo

Mkuntho unawomba pamalopo, ndikuwononga kuyika kwa LV pamalo achitetezo ndikupangitsa 36.5 kE zotayika pantchito. Kukhalapo kwa oyendetsa mphezi kunalepheretsa nyumbayo kuti igwire moto, koma zida zamagetsi zomwe zidawonongedwa sizinatetezedwe ndi omwe amamangirira, mosemphana ndi malingaliro a UTE C-15443 ndi IEC 62305.

Pambuyo pofufuza za equipotentiality ndi earthing ya magetsi, ndikutsimikizira kukhazikitsidwa kwa oyendetsa mphezi ndikuwunika momwe maelekitirodi apadziko lapansi alili, chigamulocho chidatengedwa kuti akhazikitse omanga opaleshoni.

Surge arresters adakhazikitsidwa pamutu pakukhazikitsa (bolodi yayikulu yogawa LV) ndikuwonongeka munyumba iliyonse yopanga (onani chithunzi 1 pamwambapa). Popeza kulumikizana kwa ndale komwe kunali TNC, chitetezo chimangoperekedwa munjira yofananira (pakati pamagawo ndi PEN).

Chithunzi 2 - SPD Type 2 ndi 3 - Kuteteza / kuthamanga kwakanthawi kwamphamvu zamagetsi

  • In (8 / 20µs) kuchokera ku 5 kA mpaka 60 kA
  • IMax (8 / 20µs) kuchokera ku 10 kA mpaka 100 kA
  • Up kuchokera 1 kV mpaka 2,5 kV
  • Uc = 275V, 320V, 385V, 440V, 600V
  • 1P mpaka 4P, 1 + 1 mpaka 3 + 1
  • Monoblock ndi pluggable
  • TT, TNS, IT
  • Kuyanjana kosintha koyandama

Mogwirizana ndi kalozera UTE C-15443 Ponena za kugwira ntchito pamaso pa oyendetsa mphezi, mawonekedwe a LSP (Arrester Electric) SPDs SLP40 ndi FLP7 omwe amangidwa ndi awa:

  • Pamutu pa kukhazikitsa
    In = 20 kA, ineMax = 50 kA, Up = 1,8 kV
  • Powonongeka (osachepera 10 m kupatukana)
    In = 10 kA, ineMax = 20 kA, Up = 1,0 kV

Pachitseko, chitetezo chabwino chimaperekedwa kumabwalo achiwiri ogawa (maofesi ndi malo achitetezo).

Pomwe kulumikizana kosaloza nawo mbali kumasinthidwa kukhala TNS, chitetezo chimayenera kuperekedwa munjira yofananira (pakati pa gawo ndi PE) ndi njira zosiyanitsira (pakati pazigawo ndi ndale). Zida zodumphira, pankhaniyi, ndizoyendetsa dera lomwe likutha 22 kA.

Phunziro // Kukhazikitsa kwa Protector Protector

Kanemayo akuwonetsa kukhazikitsidwa koyenera kwa chitetezo cha surge, kuphatikiza ndi chitetezo chobwezeretsa (breaker breaker). Pulogalamu ya "Lamulo la 50 wiring wiring ”kufotokozera ikuthandizani kuti mumvetse zolumikizira zolondola malinga ndi kukhazikitsa IEC 60364-5-534.
