Lawv yuav tsum ua haujlwm yooj yim yam tsis muaj kev cuam tshuam. Kev sib cuam tshuam yuav tsum ua tau raws li "Tsib-Kev Tiv Thaiv" cov cai. Tom qab ntawd, siv cov roj lubricating rau cov khoom txav mus los.
◇ Raws li Tshooj 3 ntawm phau ntawv no thiab daim ntawv qhia txog lub Hoobkas, xyuas cov txheej txheem rwb thaiv tsev, lub voj tsis kam ntawm lub switchgear, thiab cov yam ntxwv ntawm lub tshuab hluav taws xob. Cov txiaj ntsig kev xeem yuav tsum ua raws li lossis zoo ib yam li daim ntawv tshaj tawm ntawm lub Hoobkas.

Kho thiab Overhaul

◆ Cov neeg siv yuav tsum tsis tu ncua tu thiab kho dua tshiab ntawm lub switchgear. Cov ntsiab lus muaj xws li:
◇ Ntxuav cov plua plav tawm ntawm txhua qhov chaw, tshwj xeeb tshaj yog cov plua plav pov tseg ntawm qhov chaw ntawm cov khoom siv insulating;
◇ Tshawb xyuas cov khoom txav mus los thiab tsis tu ncua siv cov roj lubricating kom lawv hloov tau thiab txhim khu kev qha hauv kev ua haujlwm;
◇ Kev saib xyuas cov khoom xws li cov khoom siv hluav taws xob, cov hloov hluav taws xob cais, thiab cov hloov hluav taws xob hauv av yuav tsum tau ua raws li lawv cov ntawv qhia;
◇ Tshawb xyuas seb qhov chaw tiv thaiv hluav taws xob puas nyob zoo, seb puas muaj cua sov, thiab seb qhov hluav taws xob hluav taws xob puas muaj hluav taws xob;
◇ Tsis tu ncua xyuas seb cov fasteners raug nruj.
◆ Cov neeg siv feem ntau ua teeb meem nrog kev pab ntawm cov chaw tsim khoom. Yog tias nws tsuas yog hloov me me lossis qhov ua txhaum me me xwb, tus neeg siv yuav tsum xa mus rau phau ntawv no thiab cov lus qhia ntawm cov khoom tseem ceeb rau tus kheej - kho.
