Medium-frequency DC qhov chaw vuam tshuab yog cov cuab yeej tseem ceeb hauv ntau daim ntawv thov kev lag luam, tab sis lawv kuj tuaj nrog cov khoom siv hluav taws xob siab uas yuav tsum tau ua tib zoo saib xyuas kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Hauv tsab xov xwm no, peb yuav tham txog cov lus ceeb toom tseem ceeb uas yuav tsum tau ua thaum ua haujlwm nrog cov khoom siv hluav taws xob siab ntawm cov tshuab no.
- Cov Neeg Ua Haujlwm Tsim Nyog: Tsuas yog cov neeg ua haujlwm raug cob qhia thiab tsim nyog yuav tsum ua haujlwm lossis ua haujlwm ntawm qhov nruab nrab zaus DC qhov chaw vuam tshuab. Qhov no yog qhov tseem ceeb kom txo qis kev pheej hmoo ntawm kev sib tsoo thiab xyuas kom zoo ntawm cov khoom siv hluav taws xob siab.
- Hluav taws xob cais: Ua ntej kev saib xyuas lossis tshuaj xyuas, xyuas kom meej tias lub tshuab raug txiav tawm tag nrho ntawm lub zog. Cov txheej txheem kaw tawm / tagout yuav tsum tau ua raws li txhawm rau tiv thaiv kev ua kom lub zog tsis txaus ntseeg.
- Cov iav tiv thaiv: Ib txwm hnav cov khoom tiv thaiv tus kheej tsim nyog, suav nrog cov hnab looj tes tiv thaiv thiab tsom iav kev nyab xeeb, thaum ua haujlwm nrog cov khoom siv hluav taws xob siab. Cov iav no pab tiv thaiv hluav taws xob poob siab thiab lwm yam kev phom sij.
- Kev tshuaj xyuas tsis tu ncua: Ua haujlwm niaj hnub tshuaj xyuas cov khoom siv hluav taws xob siab, suav nrog cov cables, cov khoom txuas, thiab cov rwb thaiv tsev. Nrhiav cov cim qhia ntawm kev hnav, kev puas tsuaj, lossis kub dhau, thiab hloov cov khoom tsis raug tam sim ntawd.
- Hauv av: Xyuas kom lub tshuab ua kom zoo hauv av kom tsis txhob muaj hluav taws xob tawm thiab txo qhov kev pheej hmoo ntawm hluav taws xob poob. Tsis tu ncua xyuas cov av hauv av kom muaj kev ncaj ncees.
- Kev ntsuas hluav taws xob: Siv cov ntsuas hluav taws xob kom paub meej tias cov khoom siv hluav taws xob siab yog de-energized ua ntej ua haujlwm rau lawv. Tsis txhob xav tias lub tshuab muaj kev nyab xeeb vim tias nws tau muab tua; ib txwm txheeb xyuas nrog cov cuab yeej ntsuas tsim nyog.
- Zam dej thiab noo noo: Khaws cov khoom siv hluav taws xob ntau kom deb ntawm dej los yog noo noo kom tiv thaiv hluav taws xob arcing thiab muaj peev xwm luv luv. Khaws lub tshuab rau hauv qhov chaw qhuav thiab siv cov ntaub ntawv tsis muaj dej noo thaum tsim nyog.
- Kev cob qhia: Muab kev cob qhia zoo rau txhua tus neeg ua haujlwm uas ua haujlwm lossis tswj lub tshuab vuam. Xyuas kom lawv paub txog lub tshuab cov khoom siv hluav taws xob siab thiab cov txheej txheem kev nyab xeeb.
- Teb ceev xwm ceev: Muaj cov phiaj xwm daws teeb meem thaum muaj xwm txheej ceev, suav nrog cov txheej txheem los daws cov teeb meem hluav taws xob. Xyuas kom txhua tus neeg ua haujlwm paub yuav ua li cas teb thaum muaj xwm txheej ceev.
- Cov ntaub ntawv: Khaws cov ntaub ntawv ntxaws ntxaws ntawm kev saib xyuas, kev tshuaj xyuas, thiab kev hloov kho uas tau ua rau qhov siab-voltage seem ntawm lub tshuab. Cov ntaub ntawv no tuaj yeem yog qhov tseem ceeb rau kev daws teeb meem thiab ua kom muaj kev ua raws li cov cai tswj kev nyab xeeb.
Hauv kev xaus, thaum nruab nrab zaus DC qhov chaw vuam tshuab yog cov cuab yeej tseem ceeb hauv kev lag luam, lawv kuj ua rau muaj kev pheej hmoo vim lawv cov khoom siv hluav taws xob siab. Los ntawm kev ua raws li cov kev ceev faj no thiab ua ntej kev ntsuas kev nyab xeeb, cov neeg ua haujlwm thiab cov neeg ua haujlwm saib xyuas tuaj yeem ua haujlwm ruaj khov thiab ua haujlwm zoo nrog cov tshuab no, txo qis kev pheej hmoo ntawm kev sib tsoo thiab ua kom lawv muaj kev ntseeg siab ntev.
