[tu paub] yuav ua li cas kom paub qhov tseeb ntawm kev tseeb thiab tsis tseeb lub teb chaws tus qauv
Nws yog qhov tseeb tias nws yeej muaj tseeb thiab tsis tseeb, thiab nws yeej muaj tseeb thiab tsis tseeb. Niaj hnub no, tus qauv uas tsis yog standard thiab lub teb chaws tus qauv xaim thiab cable ntawm kev ua lag luam yog tiag tiag. Qee yam ntawm cov khoom uas ua los ntawm cov kab uas tsis yog tus qauv muaj kev txawj ntau dua li lub teb chaws. Nws yog tiag tiag nyuaj rau paub qhov txawv ntawm qhov tseeb thiab tsis tseeb, yog li yuav ua kom paub qhov tseeb qhov tseeb thiab tsis tseeb teb chaws kab. Cov nram qab no rau 6 txoj kev pom zoo:
1. Saib cov ntawv pov thawj khoom tsim
Saib cov ntawv pov thawj zoo; pom yog tias daim ntawv pov thawj yog tsim kho; xyuas yog tias muaj lub koom haum lub npe, qhov chaw, tshuaj ntsuam tshooj, hnub pib siv; saib yog tias lub cim yog luam tawm ntawm cov hlau, specifications, voltage, thiab lwm yam. Ib daim ntawv pov thawj ntawm cov tuam txhab tsim muaj. Yog tias tsis muaj ntaub ntawv pov thawj tseeb daim ntawv pov thawj, lub tuam txhab kev ua lag luam yuav tau xyuas nws kom zoo zoo.
2. Weighing, ntev
Cov xov zoo zoo yog feem ntau hauv cov nyhav nyhav. Piv txwv li, feem ntau siv cov yas tho hlua khi uas muaj ib qho hlua khau tooj hlau uas muaj qhov sib npaug ntawm 1.5mm2 yog 1.8-1.9kg rau 100m; cov yas tho hlua tiv thaiv ib leeg kheej-tooj hlau tooj hlau xaim ntawm 2.5mm2 yog 3 ~ 3.1kg rau 100m; cov yas ntawm 4.0mm2 Insulated single-strand tooj liab hlau yog 4.4 mus rau 4.6 kg ib 100 m qhov ceeb thawj. Puas yog cov neeg pluag tsis zoo nyhav dhau los? Los yog nws tsis ntev txaus? Los yog xaim muaj ntau hom tooj liab tseem ceeb. Muaj ntau qhov, lub teb chaws tsis yuam kom ua si, tab sis muaj ntau lub lag luam kuj ua si nplej, ua si txhom tsis yog lub teb chaws tus qauv, tab sis feem ntau lub teb chaws feem ntau tsis ua si mov. Cov txhuv tsis muaj txuj cai tsuas yog muaj kev txhais tau tias, lub teb chaws tus qauv kab dav ntev yog 100 meters. Koj yuav tsum ntsuas qhov ntsuas kab hlau nrog lub micrometer. Tam sim no qhov tsawg kawg nkaus hlau loj hauv tsev yog 2.5 square meters. 1.5 yog tsis ua si ntxiv lawm. Niaj hnub no cov lag luam feem ntau txiav qhov chaw tiaj, BV2.5 square-ib plhis yas tooj liab hlau tub ntxhais yuav tsum yog 1.78mm, sab diameter (nrog rau tawv) 3.9mm. BV4 square single-strand yas tooj liab hlau tub ntxhais yuav tsum yog 2.25 hli, txheej inch (nrog rau tawv) 4.4mm.
3. Saib ntawm tooj
Qhov ntau dua qhov ci ci ntawm tooj liab, qhov zoo dua qhov tooj liab, thiab qhov smoothness, luster, thiab tsis muaj layering. Tus tsim nyog tooj liab tub ntxhais cov tub ntxhais yuav tsum yog xim liab, ci iab thiab muag. Yog tias koj tuaj yeem txiav tawm ntawm daim tawv nqaij ntawm daim tawv nqaij, ua tib zoo saib ntawm tooj hlau xaim hauv qab, kov sab saum toj ntawm tus tooj liab hlau nrog koj xibtes, muaj kev sib txoos thiab tingling, xav softer, thiab tub tooj tooj liab ntawm qhov tsis tshuav tooj liab tseem ceeb yog liab dub. , daj los yog dawb, nrog ntau impurities, pluag txhua yam muaj zog, pluag toughness, yuav ua txhaum thaum siv me ntsis, thiab muaj ntau zaus tawg tawg nyob rau hauv lub xaim. Thaum kuaj xyuas, koj tsuas tau tev lub xaim 2CM ntawm ib kawg, ces siv ib daim ntawv dawb los txhuam nws me ntsis ntawm tus tub tooj tooj liab. Yog tias muaj cov yeeb tshuaj dub rau ntawm daim ntawv dawb, nws txhais tau tias muaj ntau impurities ntau hom tooj liab. Tsis tas li ntawd, qhov tsis zoo ntawm cov hlau thaiv txheej zoo li yuav tuab heev, thiab qhov tseeb nws yog ua los ntawm cov khoom yas siv. Dhau lub sij hawm, qhov txheej txheem tiv thaiv kab yuav muaj hnub nyoog thiab xau tawm.
4. Kev sim siab
Nws yog ib qho tsim nyog kom pheej khoov ib lub taub hau xuas tes. Tus neeg twg uas muaj tes xuas tes, zoo rau qaug zog, muaj zog yas lossis rubber zoo thiab tsis tawg rau ntawm cov hlau thaiv kev yog qhov khoom zoo tshaj plaws. Nyob rau tib lub sijhawm, vim tias cov nqi ntawm cov cuav thiab cov hlua khau khov yog tsawg, li ntawd yuav muaj qhov txawv txav hauv kev xav. Nws yog feem ntau muag ntawm ib qho tsawg nqi thiab pheej yig, ua rau nws nyuaj rau qhov txawv qhov tseeb.
5. Kev kuaj xyuas
Cov rwb thaiv tsev ntawm cov khoom cuav zoo li yuav tuab heev? Tab sis qhov tseeb, lawv feem ntau yog tsim los ntawm cov khoom siv coj los siv. Cov khoom muaj pluag toughness, pluag tsis kam mus puas tsuaj, thiab yooj yim rau tev tawm tawg. Tshwj xeeb tshaj yog nyob rau hauv tus txheej txheem ntawm tsev kho kom zoo nkauj, nws yog ib qho yooj yim heev hnav. Muaj kev ruaj ntseg loj loj. . Ntev npaum li cas qhov kev thaiv txoj hlua qub tsis muaj hlau impurities rau hauv cov khoom, nws tuaj yeem dhau kev sim siab. Txawm li cas los xij, tus neeg siv nruab nrab tuaj yeem txawv qhov zoo ntawm lub tsho los ntawm txoj kev ncab yooj yim. Cov insulating sheath ntawm cov ntaub ntawv tuaj yog feem ntau doped nrog calcium carbonate, uas yuav tshwm sim dawb thiab yooj yim so thaum lub sij hawm ncab.
6. Hlawv nrog hluav taws.
Cov xov hlau thiab cov cab cab yuav kub hnyav sai sai nrog hluav taws, thiab yuav muaj qhov qhib hluav taws thiab pa taws. Cov cab zoo zoo hlawv qeeb, muaj pa taws tsawg lossis haus luam yeeb, thiab tsis muaj hluav taws qhib.
