Lub caij ntuj sov yog lub caij uas nquag cua daj cua dub, rau sab nraum zoovhnub ci txoj kev teeb, Nws yog ib qho tsim nyog yuav tsum tau teeb tsa kev tiv thaiv xob laim, vim nws qhov siab, thiab lwm yam Nws yog ib qho yooj yim rau kev tawm tsam los ntawm hluav taws xob xob laim, hnub ci txoj kev teeb ci xob laim feem ntau muaj plaub hom: hloov overvoltage, yuav tsum yog xob laim, hluav taws xob hluav taws xob, hluav taws xob ncaj qha. .Yog li hnub ci txoj kev teeb yuav ua li cas tiv thaiv xob laim?Rau qhov teeb meem no, tom ntej no amber teeb pom kev zoo rau txhua leej txhua tus los qhia.
Ua ntej, tus ncej lub cev tau txais flash
Txhawm rau tiv thaiv kom tsis txhob xob laim los ntawm kev sib tsoo lub hnub ci txoj kev teeb ncej, tus ncej yuav tsum tau ua rau hauv lub teeb nyem, yog li ntawd thaum xob laim tuaj yeem ua rau xob laim ncaj qha rau nws tus kheej, ua haujlwm ncaj qha hluav taws xob tawm.
Thib ob, hluav taws xob grounding
1. Kev tiv thaiv hauv av
Txhawm rau tiv thaiv cov khoom xau thaum ua rau muaj kev phom sij rau kev nyab xeeb ntawm tus kheej thiab cov cuab yeej siv, txhua yam khoom siv hluav taws xob nthuav tawm cov khoom siv hluav taws xob los ntawm cov xaim hluav taws xob hauv av yuav tsum ua raws li cov kev cai tiv thaiv kev tiv thaiv.
2. Kev ua haujlwm hauv av
Ncaj nraim hauv av qhov nruab nrab ntawm qhov hluav taws xob qis hluav taws xob, qhov system grounding kuj yuav tsum tsawg dua 10Ω.
3. xob laim av
Txhawm rau tiv thaiv cov khoom siv hluav taws xob los ntawm xob laim hluav taws xob, cov hlua hluav taws xob, cov hlua hluav taws xob thiab cov khoom siv hluav taws xob thiab lwm yam khoom siv tiv thaiv hluav taws xob rau hauv av, kev tiv thaiv hauv av yuav tsum tsawg dua 10Ω.
Peb, hlau zeroing
Lub plhaub hlau ntawm cov khoom siv hluav taws xob, hlau thav duab, thiab lwm yam thiab kev sib txuas hauv av nruab nrab.Grounding hlau yuav tsum tau siv insulated hlau, thiab siv tag nrho cov kab, tsis muaj pob qij txha nyob rau hauv nruab nrab.xob laim ntes cov kab hauv av yuav tsum tau xaiv rau qhov luv luv rau txoj kab hauv av.Cov cuab yeej tiv thaiv kab kab hla ntu ntawm S ≤ 16mm2, grounding wire thiab tiv thaiv kab me me cross-sectional cheeb tsam ntawm S, 16 ≤ 35 grounding wire thiab tiv thaiv kab me me hla ntu ntawm 16, S > 35 grounding wire thiab tiv thaiv kab me me cross-sectional cheeb tsam ntawm S / 2, grounding hlau vuam ntev ca steel ≥ 2 npaug ntawm qhov dav ntawm lub tiaj tus hlau.
Plaub, kev tiv thaiv Circuit Court
Kev teeb tsa tshwj xeeb hnub ci hluav taws xob tiv thaiv, raws li lub hnub ci txoj kev teeb hluav taws xob tsim hluav taws xob tsim hluav taws xob, huab cua xob laim, hnub ci txoj kev teeb hluav taws xob yuav raug tsim los ntawm electrostatic induction lossis electromagnetic induction ntawm lub ncov siab tam sim no lossis tam sim no ncov los ntawm, cuam tshuam rau lub hnub ci LED cov khoom siv teeb pom kev zoo.Hnub ci txoj kev teebhluav taws xob tiv thaiv tshwj xeeb yog los tiv thaiv cov kab hluav taws xob hluav taws xob hluav taws xob, tuaj yeem zam tib thaj tsam ntawm hnub ci txoj kev teeb pom kev puas tsuaj tshwm sim.
Cov saum toj no ntawm lub hnub ci txoj kev teeb yuav ua li cas tiv thaiv xob laim tawm tsam rau koj los qhia ntawm no, luv luv, nyob rau lub caij ntuj nag xob nag cua tsis tu ncua, hnub ci txoj kev teeb hluav taws xob tiv thaiv kev ua haujlwm yuav tsum tau ua ua ntej, raws li txoj kev ua haujlwm saum toj no, tuaj yeem zam kom zoohnub ci txoj kev teebnyob rau hauv cov ntaub ntawv ntawm xob laim tshwm sim los ntawm qhov tsis tsim nyog raug mob.
