Vim li cas kuv yuav tsum tau grounding, thiab yuav ua li cas mus cuag ib tug private tsev

Zoo tag nrho cov khoom uas muaj feem rau hluav taws xob, nws yog tsim nyog los tiv thaiv cov neeg los ntawm hluav taws xob poob siab. Sawv daws yeej paub yog vim li cas koj yuav tsum av, tab sis heev ob peb cov neeg, yuav ua li cas kom zoo zoo teem kom nws siab fulfills nws zog.

Yog hais tias koj xa mus rau ib tug grounding ntaus tag nrho cov hlau qhov chaw ntawm cov khoom, ces thaum koj yuj dua lawv tej zaum hluav taws xob tam sim no yuav mus rau hauv lub hauv av. Ces, thaum koj kov cov hlau los ntawm ib tug txiv neej tuav ib tug ntau me me tam sim no yog tsis txaus ntshai rau nws.

Yuav ua li cas yog hluav taws xob txais kev pab?

Hluav taws xob nkag los ntawm ib qhov chaw ntawm thawj hwj chim kav nyob rau hauv ib tug substation, thiab ces - qhov tau txais kev pab. Rau kis tau tus mob siv peb theem conductors. Qhov thib plaub neeg xyuas pib yog lub ntiaj teb. Lub peb-theem substation transformer windings yog kev cob cog rua nyob rau hauv ib tug "lub hnub qub". Cov hom point (nruab nrab) tej zaum-grounded. Qhov no yog tsim nyog rau lub qub lag luam los ntawm hluav taws xob khoom. Tej grounding yog hu ua ib tug ua hauj lwm es tsis tiv thaiv.

Nyob rau hauv chav tsev feem ntau yog thov voltage ntawm 220 V ntawm lub theem thiab nruab nrab conductors mus rau ib tug ntau hluav taws xob ntaub thaiv npog. Nyob rau hauv ib tug ntiav tsev yuav tsum xeem nyob rau 380 - peb theem thiab nruab nrab. Cov ua yog ces diverge rau hauv outlets thiab teeb pom kev zoo pab kiag li lawm rau tag nrho cov thaj chaw. Nws yuav tsum tsis txhob hnov qab txog vim li cas koj yuav tsum av. Yuav kom tiv thaiv hluav taws xob poob siab, ua ke nrog rau cov theem thiab nruab nrab conductors nteg lwm - grounding.

Yuav ua li cas los tiv thaiv koj tus kheej los ntawm hluav taws xob poob siab?

Ib txoj kev ntawm suav hluav taws xob poob siab los yog zoo heev txo nws, yog lub installation ntawm grounding pab kiag li lawm. Vim li cas peb yuav tsum tau av voj? Nws yog tsim nyog rau cov khoom siv nrog hlau tsev nyob: ntxuav machines, hluav taws xob cookers, tub yees, etc.

Thaum koj yuj lub peev xwm nyob rau hauv nws yog xim hlau tsev nyob tsev neeg cov khoom tam sim no yuav tsum mus rau hauv av. Tab sis rau no koj thawj zaug yuav tsum ua kom ib tug ntaus ntawv nyob rau hauv daim ntawv ntawm hlau, ua rau hluav taws xob kev sib cuag nrog rau hauv av. Tej zaum nws yuav khoom los yog muaj conductive ntsiab kos nyob rau hauv lub ntiaj teb.

grounding qhov hluav taws xob

Vim li cas peb yuav tsum tau grounding ntawm hluav taws xob khoom siv nyob rau hauv lub xub ntiag ntawm hlau tus neeg mob los yog lwm yam khoom? Lo lus nug no yog to taub los ntawm ntau yam. Lawv yuav ua tau ntawd energized puas hlau rwb thaiv tsev los yog luv luv Circuit Court, uas yog txaus ntshai rau ib tug neeg nyob rau hauv lub sij hawm ntawm kov ub kov no.

Qhov no kuj siv rau hlau qhov chaw ntawm lub teeb thiab chandeliers. Nyob rau hauv pej xeem lub tsev hlau loj ntawm los ntawm 2.5 hli ² yog pw nyob rau txhua lub qhov hluav taws xob. Yog vim li cas peb yuav tsum tau grounding nyob rau hauv lub nplos? Nws yog tsim nyog mus cuag lub ntiaj teb no los nws hu mus rau ib tug neeg hauv tsev neeg kws. Txwv tsis pub, lub tsheb yuav muaj rau yuav pw thoob plaws hauv lub chav tsev thiab ua los ntawm cov kev twb kev txuas rau lub cev ntawm txhua ntaus ntawv uas yog tsis heev aesthetically pleasing.

Hauv pem teb hu cov txheej txheem thiaj li hais tias lawv muaj kev cob cog thawj, sai li sai raws li lub plug los ntawm cov tsev neeg kws qaum mus rau hauv lub hwj chim qhov hluav taws xob. Yog hais tias lub nplos yog kev cob cog rua lub voj, av yog thov nyias mus nyias ntawm lawv los ntawm lub hlws ris lub thawv.

Nruab av

Yog li ntawd, yog vim li cas peb yuav tsum tau av nyob rau hauv ib tug tu tsev? Nws yog tsim nyob rau hauv daim ntawv ntawm ib tug kaw lub voj. Daim ntawv tej zaum yuav muaj, tab sis yam tsawg kawg ntawm tag nrho cov ntaub ntawv consumed nyob rau hauv lub voos. Nrog lub perimeter ntawm equilateral triangle trench yog khawb nyob rau hauv lub hauv av mus rau ib tug tob ntawm 1 m, thiab cov vertices yog hammered steel kav dej lossis cov ces kaum ntawm 2.5 m. Nyob rau hauv thiaj li yuav tiv thaiv xeb yog zoo dua siv ntaub ntawv nrog ib tug zinc los yog tooj liab plated. lub electrodes yuav tsis tau pleev xim rau. Ua tau tsuas yog cov kua roj vanish weld cheeb tsam.

Lub electrodes yuav tsum protrude 20 cm los ntawm lub hauv qab ntawm lub trench. Circuit Court hlab sawb, thiab nws yog muab los ntawm cov neeg xyuas pib grounding ntawm tib cov ntaub ntawv uas mus rau lub tsev. Thaum cov dawb kawg ntawm lub ntsia liaj qhov rooj yog welded, thiab yog cov tswv yim rau hluav taws xob tswj nyob ntawm tej PE-section 6 hli ² los yog ntau tshaj. Ib ohmmeter qhia tau tseeb lub fais kuj ntawm lub Circuit Court. Raws li cov SAE yuav tsum rau thaj vaj tse, nws yuav tsum muaj tsawg tshaj 30 ohms.

Yog hais tias lub Performance index tshaj qhov kws txwv, ib co ntxiv Circuit Court daig cov fab, thiab ua ib tug jumper. Yog li, los ntawm kev ua cov cheeb tsam ntawm kev sib cuag nrog rau hauv pem siv. Yuav kom txo tau cov kuj ntawm lub Circuit Court yog nqa los ntawm nws ntau xyoo tooj liab muaj siab conductivity. Tom qab lub trench yog lawm ua tus sau nrog av. Tawg pob zeb, gravel los yog siv pov tseg los siv rau qhov no yog tsis tau tso cai. Siv ceev cov ntaub ntawv uas ya raws: av nplaum, peat, av zoo ua qoob.

tej zaum equalization

Niaj hnub no, txawm yog me nyuam paub yog vim li cas koj yuav tsum av. Nws yog ib qho tseem ceeb los xyuas kom meej ib tug yuav txo tau ntawm lub peev xwm sib txawv rau ntawm qhov chaw rau tib neeg kov thiab yog tsis ua stepwise voltage. Nyob rau ntawm qhov chaw, nyob rau hauv ib lub kaw Circuit Court, lub peev xwm hloov ntseeg nkaws, thiab sab nraum muaj ib tug poob sharply. Yuav kom tiv thaiv no, sab nraum faus kab rov tav steel ib daim hlab tau kev cob cog rua rau lub electrodes.

Raws li cov kev cai ntawm lub SAE tiv thaiv lub ntiaj teb no yog ua los ntawm tooj liab. Ntawm kev muag khoom muaj cov tshwj xeeb cov khoom siv, tab sis lawv yeej kim heev. Rau grounding designs private tsev feem ntau yog siv steel qhov chaw.

Yuav kom saib lub ntsab lug. Yog li ntawd, yog vim li cas peb yuav tsum grounding nyob rau hauv ib tug ntiav tsev? Ua ntej ntawm tag nrho cov nws yog kev cob cog rua nrog lub tiv thaiv ntawm cov neeg los ntawm hluav taws xob poob siab tsis muaj. Nws yog ib qho tseem ceeb los npaj hauv av voj thiab ua qhov tsim nyog hluav taws xob sib txuas. Yuav ua li cas nqa tawm nws installation, thiab xaiv cov ntaub ntawv, nyob rau hauv lub noj qab haus huv thiab kev nyab xeeb ntawm neeg.
