Dab tsi yog ib qholub tshuab hluav taws xob xau?
Lub tshuab hluav taws xob xau, yog siv los tiv thaiv kev poob hluav taws xob. Thaum muaj kev xau, lub zog sib nqus raug tsim los ntawm lub ntsiab sib cuag, lub kauj faib sib cuag, lub kauj faib sib cuag thiab lub qhov hloov tseem ceeb.
Lub tshuab hluav taws xob xaukev ua haujlwm: thaum lub voj voog luv luv lossis overload tuaj yeem ua tiav raws sijhawm, txiav tawm lub zog fais fab.
Thaum muaj ib lub cuab yeej tiv thaiv kev xau hauv lub voj voog, yog tias muaj teeb meem xau lossis overload tshwm sim, lub cuab yeej tiv thaiv kev xau yuav tsis ua haujlwm thiab yuav xa suab thiab lub teeb ceeb toom. Tsis tas yuav txiav tes.
Lub hom phiaj tseem ceeb:
1. Tiv thaiv kev nyab xeeb ntawm tus kheej thaum muaj kev xau ntawm cov khoom siv hluav taws xob hauv tsev lossis cov khoom siv ua ke.
2. Nws yuav tsum tau teeb tsa rau hauv cov chaw pej xeem thiab cov chaw uas yooj yim tawg (xws li cov chaw ua haujlwm tsim khoom, cov tsev rau khoom, thiab lwm yam) uas tib neeg feem ntau tsiv mus los kom tiv thaiv hluav taws thiab lwm yam xwm txheej uas tshwm sim los ntawm kev xau hluav taws xob.
Tsis tuaj yeem sib koom lub zog hluav taws xob nrog lwm cov khoom siv hluav taws xob.
1. Lub qhov hluav taws xob tiv thaiv kev xau tuaj yeem txiav tawm lub hwj chim sai sai yog tias muaj ib theem grounding luv luv lossis grounding fault hauv lub zog hluav taws xob qis-voltage, yog li ua kom muaj kev nyab xeeb ntawm tus kheej thiab cov khoom siv tiv thaiv kom tsis txhob raug puas tsuaj.
2. Yog tias lub qhov hluav taws xob thiab cov khoom siv hluav taws xob ua tsis tiav tib lub sijhawm, qhov teeb meem ntawm cov khoom siv hluav taws xob tuaj yeem raug tshem tawm kom tsis txhob ua rau lub zog hluav taws xob poob tag, yog li ua kom muaj kev nyab xeeb ntawm tus kheej thiab tiv thaiv kev nthuav dav ntawm kev raug mob hluav taws xob.
3. Hauv peb-theem plaub-xaim hluav taws xob qis-voltage fais fab grid, thaum muaj qhov txhaum av ib-theem tshwm sim, lub zog muab hluav taws xob tuaj yeem txiav tawm sai thiab raws sijhawm kom tiv thaiv kev nthuav dav ntawm qhov xwm txheej.
4. Qhov kev xaiv ntawm qhov kev tiv thaiv kev xau yog qhov zoo heev vim nws muaj ob txoj haujlwm ntawm kev tso tawm overcurrent (TN -C) thiab kev tso tawm overload (TT-B).
5. Thaum ob lub ntsiab lus ntawm lub cev muaj zog raug av vim yog hluav taws xob poob siab lossis vim qee qhov laj thawj, lub zog fais fab tuaj yeem raug txiav tawm sai thiab ntseeg tau.
Tsis txhob siv hluav taws xob ib theem rau teeb pom kev zoo.
Kev teeb tsa kev tiv thaiv kev xau: 1. Kev teeb tsa kev tiv thaiv kev xau yuav tsum ua raws li cov cai tswjfwm, nws qhov chaw yuav tsum ruaj khov thiab txhim khu kev qha, thiab yuav tsum tau xauv raws li qhov xav tau.
2. Tus neeg siv yuav tsum txiav txim siab qhov ntsuas ntawm cov khoom tiv thaiv kev xau raws li kev siv tshwj xeeb, tab sis feem ntau yuav tsum tsis pub tshaj qhov tam sim no ua haujlwm zoo (30mA).
3. Tus qauv thiab cov lus qhia ntawm tus tiv thaiv kev xau yuav tsum tsim nyog rau txoj kab txuas.
4. Cov kawg ntawm cov khoom tiv thaiv kev xau thiab ob qho kawg ntawm txoj kab thauj khoom yuav tsum muaj kev sib cuag zoo thiab yuav tsum ruaj khov thiab txhim khu kev qha.
5. Yog tias pom tias siv lub tshuab tiv thaiv xau muaj suab nrov txawv txawv, kub nce, tes tsis zoo li qub, thiab lwm yam, yuav tsum nrhiav tus kws hluav taws xob kom kuaj xyuas thiab kho.
6. Cov khoom tiv thaiv xau yuav tsum tsis txhob siv ntev thiab feem ntau yuav tsum tsis txhob siv ntau tshaj ib nrab xyoo. Yog tias tsim nyog siv cov khoom tiv thaiv no, yuav tsum tau kuaj xyuas tag nrho ua ntej siv.
Tsis tuaj yeem hloov pauvlub tshuab hluav taws xob xaunrog lub qhov (socket) ib txwm muaj.
Vim tias lub qhov (socket) ib txwm muaj lub plhaub hlau thiab cov xov hlau sab hauv uas tsis tuaj yeem tiv thaiv tau, yog li thaum muaj kev xau, hluav taws xob yuav nkag mus rau hauv lub cev los ntawm lub qhov (socket), ua rau muaj kev sib tsoo hluav taws xob.
Kev siv hluav taws xob kom muaj kev nyab xeeb yog qhov tseem ceeb heev. Nws tsis yog tsuas yog txhawj txog peb txoj kev nyab xeeb xwb, tab sis kuj txhawj txog cov neeg nyob ib puag ncig peb thiab. Yog tias koj tsis ua tib zoo saib xyuas kev siv hluav taws xob thaum muaj kev nyab xeeb, kev tsis saib xyuas me ntsis yuav ua rau muaj hluav taws xob poob. Yog li ntawd, hauv lub neej txhua hnub, koj yuav tsum tsim kom muaj tus cwj pwm zoo ntawm kev siv hluav taws xob kom muaj kev nyab xeeb.
Lub qhov hloov tiv thaiv kev xau tuaj yeem ua tiav kev ceeb toom hluav taws xob ua ntej, kev saib xyuas hluav taws xob, kev pov tseg hluav taws xob thiab lwm yam haujlwm. Lub qhov hloov tiv thaiv kev xau tuaj yeem ntsia tau rau hauv chav faib khoom thiab tuaj yeem ntsia tau rau txhua qhov xav tau los tiv thaiv qhov chaw, tuaj yeem txo qhov tshwm sim ntawm kev sib tsoo los ntawm kev xau.
Thaum siv ib qholub tshuab hluav taws xob xau, cov teeb meem hauv qab no yuav tsum tau sau tseg:
1. Ua ntej yuav txhim kho lub tshuab hluav taws xob xau, yuav tsum tau kuaj xyuas seb cov kab txuas ntawm lub tshuab hluav taws xob xau puas zoo thiab seb cov xov hlau puas ua tau raws li cov lus qhia. Yuav kom ntsuas seb tus nqi tam sim no ntawm lub tshuab hluav taws xob xau puas nyob hauv qhov ntau thiab tsawg, yuav tsum tsis muaj qhov tshwm sim tsis zoo ua ntej lub tshuab hluav taws xob xau ua haujlwm.
2. Thaum txhim kho lub tshuab hluav taws xob xau, yuav tsum tau ua tib zoo saib xyuas kev siv lub fuse nrog tus nqi tam sim no thiab yuav tsum txiav lub hwj chim ua ntej kuaj xyuas lub tshuab tiv thaiv xau. Tsis txhob siv cov tshuab hluav taws xob xau yog tias muaj lub voj voog sab nraud nkag los lossis yog tias muaj qhov yuam kev luv luv tshwm sim.
3. Thaum txhim kho lub tshuab hluav taws xob uas xau, lub tshuab hluav taws xob yuav tsum muab tso rau ntawm qhov av tiaj tiaj thiab khov kho thiab yuav tsum tau grounded lossis zeroed kom ruaj khov.
4. Tom qab kev teeb tsa, lub tshuab hluav taws xob xau yuav tsum tau kuaj xyuas tas li los ntawm kev txiav tawm lub hwj chim, thiab yog tias nws tsis tuaj yeem txuas nrog hauv 2 feeb, lub hwj chim tuaj yeem txuas nrog dua.
