Zoteteza lapansi: chitetezo eletropriborov

nthaka zoteteza imatengedwa kuti mwapadera kugwirizana magetsi pansi pa moyo mbali zitsulo, amene, chifukwa cha kutsekedwa kwa chipangizo nyumba akhale moyo. Izi zimachitika pa kugwirizana mwachisawawa magetsi a moyo mbali zachitsulo wa amagetsi ndi zinthu conductive, ndi voteji zingachitikenso Mwachitsanzo, mphezi.

Ndi dziko lapansi oteteza kumatha ngozi mantha magetsi pamene wokhudza mbali moyo wa thupi chitsulo kapena zida zomwe, chifukwa cha earthing anaonekera amayesetsa.

Ayenera kukhala wosiyana ntchito earthing zoteteza, limene lakonzedwa kuti kugwira bwino ntchito makhazikitsidwe magetsi, komanso nthaka kutetezera mphezi. Ndi ntchito zingaphatikizepo grounding Mafunde ndale za jenereta kumulowetsa wa mphamvu thiransifoma ndi zipangizo zina.

Pakuti grounding chipangizo mukufuna kugwiritsa ntchito zipangizo zachilengedwe ndi zipangizo: zitsulo ndi mipope madzi amene alibe odana ndi dzimbiri ❖ kuyanika, kupatulapo mapaipi ndi mpweya zachiwawa kapena flammable kapena zakumwa. Oyenera grounding kutsogolera chingwe sheathing, mavavu ndi zinthu zitsulo za analimbitsa nyumba simenti kapena nyumba. Monga kudziwa kuti dzikoli ayenera kugwirizana ndi dziko lapansi. Komanso dowels abwino zitsulo kapena casing. Koma adamchitira zotayidwa ochititsa ndi chingwe sheathing zoletsedwa ntchito za nkhaniyi.

Popeza maelekitirodi masoka achilengedwe kapena ngati ali ndi kukana mkulu angagwiritsidwe ntchito ndi yokumba, amene analenga grounding zozitetezera. Iwo zopangidwa ndi zitsulo ngodya zigawo 5h5h0,5 masentimita kutalika mamita 2-3, kukula yemweyo a mipope zitsulo ndi awiri a 5 cm zitsulo zigawo zozungulira (kutalika 5 m, awiri 12,0 - 14,0 mm). mbali ntchito (maelekitirodi) ayenera kumizidwa mu nthaka pa mtunda Chrixitu mamita 3-5, zinthu zonse ziyenera kuti chikugwirizana pakati pa Mzere zitsulo, chigawo mtanda wa mamilimita 40x4.

Mzere polumikiza aikidwa mu ngalande kuti akuya mamita 0,70, mtunda wofanana pamwamba ndi malekezero chapamwamba maelekitirodi lapansi. zinthu zonse ogwirizana ndi kuwotcherera. chiwerengero cha maelekitirodi kuchita masamu, zochokera resistivity nthaka, elekitirodi kukula, ndi yozizira koopsa mozama ndi zinthu zina.

Zoteteza grounding magetsi voteji kwa zikwi B akhoza bungwe ntchito zitsulo nyumba ya nyumbayi (pamaso pa kulumikiza odalirika zinthu dera), wirings machubu zitsulo, zotayidwa m'chimake chingwe, mapaipi zachitsulo (kupatula kachitidwe chapakati Kutentha, ndi payipi zimbudzi). zitsulo trays, mabokosi, m'makola mwawo ndi busbars madera ziro waya (zoteteza lapansi ndi ndale) amagwiritsidwanso ntchito.

Monga ochititsa zoteteza ziro zoletsedwa ntchito zitsulo ndi zipolopolo woonda kutsogolera mawaya ndi zingwe. Air AC kudzatha kudzera wochititsa ndale, amene anaika pa zogwiriziza mofanana ochititsa gawo.

Komabe, zikutha sikuti sitingakumane chitetezo koyenera kuti anthu pokhudzana ndi unsembe magetsi. Nthawi zina, m'madera ndi chiopsezo zikutha, pamodzi ndi kukonzanso ntchito earthing yoteteza kapena shutdown chitetezo kuchuluka ntchito. Zoteteza mawaya ndale zoletsedwa ntchito kwa zikutha za magetsi magetsi, kudya mizere ena, monga iwo angakhoze iyimitsidwe chifukwa tikukonza.

Kuti zipangizo zodzitetezera monga breakers dera kanthu pa kutayikira panopa. Kugwiritsa ntchito zipangizo izi mu nyumba ya kusintha chitetezo magetsi.
