chav hloov . ib cheeb tsam uas muaj kev sib dhos ntawm hluav taws xob khoom siv rau kev tswj thiab kev tiv thaiv ntawm hluav taws xob circuits. a chav hloov tej zaum yuav cuam tshuam rau lub substation tab sis tsuas muaj hloov . lub ntsiab hloov cais tawm hluav taws xob yog nyob rau hauv lub ntsiab chav hloov.
Kuj kom paub yog, dab tsi yog chav switchgear?
Nyob rau hauv ib qho hluav taws xob system, switchgear yog kev sib txuas ntawm hluav taws xob disconnect keyboards, fuses lossis Circuit Court breakers siv los tswj, tiv thaiv thiab cais cov khoom siv hluav taws xob. Switchgears yog siv ob qho tib si los de-energize cov cuab yeej tso cai rau kev ua hauj lwm kom ua tiav thiab tshem tawm qhov yuam kev hauv qab.
Ib yam li ntawd, dab tsi hauv chav hluav taws xob? Ib chav hluav taws xob yog a chav los yog qhov chaw nyob rau hauv ib lub tsev tshwj xeeb rau hluav taws xob khoom siv. Nws qhov loj me feem ntau yog proportional rau qhov loj ntawm lub tsev; cov tsev loj yuav muaj lub ntsiab chav hluav taws xob thiab subiary chav hluav taws xob . Hluav taws xob switchboards. Distribution boards.
Ntawm no, LV chav tsev txhais li cas?
Hauv hluav taws xob engineering tsis tshua muaj hluav taws xob yog ib lub sij hawm txheeb ze, lub txhais txawv ntawm cov ntsiab lus. Cov ntsiab lus sib txawv yog siv rau hauv kev xa hluav taws xob hluav taws xob thiab kev xa tawm, thiab cov lej kev nyab xeeb hluav taws xob txhais " tsis tshua muaj hluav taws xob " circuits uas raug zam los ntawm kev tiv thaiv yuav tsum tau nyob rau ntawm qhov siab dua voltages.
Chav hluav taws xob loj npaum li cas?
Basic chav NEC kuj xav kom 3 mus rau 4 ko taw (1m mus rau 1.3m) ntawm txoj kab qhov chaw nruab nrab nyob hluav taws xob Cheebtsam ntawm 600 volts los yog tsawg dua, nyob ntawm seb cov khoom nyob rau ntawm ib los yog ob sab ntawm txoj kab. Qhov kev xav tau no tuav txawm tias cov khoom muaj kev tiv thaiv los ntawm kev ruaj ntseg enclosures lossis cov ntxaij vab tshaus.

Ntxig txhua lub xaim rau hauv lub qhov tsim nyog hauv qhov chaw txais khoom tshiab thiab ceev cov ntsia hlau davhlau ya nyob twg kom ruaj ntseg. Qhwv qhov kawg ntawm cov tooj liab liab lossis ntsuab xaim (hauv av) nyob ib ncig ntawm cov ntsia hlau ntsuab thiab nruj. Maj mam thawb lub qhov hluav taws xob rov qab rau hauv lub thawv thiab ceev cov ntsia hlau mounting
Dab tsi ua rau lub qhov hluav taws xob muaj hluav taws xob tsawg?
Ib qho laj thawj uas lub qhov hluav taws xob yuav muaj lowvoltageis uas nws hnav tawm. Cov hluav taws xob hluav taws xob tuaj yeem hnav tawm tib yam li txhua yam khoom siv lossis cov khoom siv hluav taws xob.Qhov txuas tsis tu ncua thiab tshem tawm cov hlua rau hauv lub qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas
Puas tuaj yeem tiv thaiv hluav taws xob tiv thaiv hluav taws xob?
Surge protectors tiag tiag yuav tiv thaiv cov khoos phis tawj thiab lwm yam khoom siv hluav taws xob los ntawm lub zog hluav taws xob thiab feem ntau cov xob laim nyob deb, tab sis lawv tsis tuaj yeem tiv thaiv lub teeb pom kev ncaj qha los ntawm kev puas tsuaj rau cov khoom siv sib txuas
Yuav ua li cas koj xaim lub tshuab hluav taws xob mus rau qhov ntsuas hluav taws xob?
Muaj peb cov xov hlau uas yuav tsum tau txuas mus rau qhov tseeb regulator davhlau ya nyob twg. Weld lub regulator mount rau lub tsheb laij teb ncej. Txuas lub regulator rau lub mount. Txuas lub roj teeb zoo cable hlau - feem ntau yog liab - rau tus tswj. Polarize lub generator los yog alternator los ntawm tus regulator
Puas yog txhua lub tshuab hluav taws xob muaj GFCI qhov hluav taws xob?
Duplex (ob chav) qhov hluav taws xob muaj nyob rau ntawm lub tshuab hluav taws xob nqa tau thiab txhua qhov khoom siv 120 volts. Hauv av txhaum kev tiv thaiv qhov hluav taws xob (GFCI) yog qhov tshwj xeeb ntawm qee cov qauv thiab tiv thaiv tus neeg siv los ntawm hluav taws xob shocks
