Kev nyab xeeb kev ua haujlwm txoj cai rau siab thiab qis voltage switchgear

1. Thaum ua hauj lwm rau tag nrho los yog ib feem ntawm cov energized disks, cov khoom tu thiab cov khoom siv khiav lag luam yuav tsum tau muab cais los ntawm cov cim pom tseeb.

2. Qhov thib ob winding nrog tam sim no transformer thiab voltage transformer yuav tsum muaj ruaj khov thiab txhim khu kev qha tiv thaiv grounding.

3. Thaum ua hauj lwm nyob rau hauv lub thib ob Circuit Court ntawm lub tam sim no transformer nyob rau hauv lub lag luam, yuav tsum tau ua raws li nram no kev ruaj ntseg ntsuas:

3.1 Nws yog nruj me ntsis txwv tsis pub disconnect lub voj tam sim no.

3.2 Txhawm rau kom ntseeg tau lub voj voog luv luv ntawm cov kauj ruam thib ob ntawm lub tshuab hloov tam sim no, yuav tsum siv lub voj voog luv luv thiab luv-circuit xaim, thiab cov xaim winding raug txwv.

3.3 Nws yog txwv tsis pub ua ib qho kev ua haujlwm ntawm lub voj thiab xaim ntawm qhov tam sim no transformer thiab luv luv-circuit davhlau ya nyob twg.

4. Thaum ua hauj lwm nyob rau hauv lub thib ob Circuit Court ntawm voltage transformer nyob rau hauv lub lag luam, yuav tsum tau ua raws li nram no kev ruaj ntseg ntsuas:

4.1 nruj me ntsis tiv thaiv luv luv Circuit Court lossis grounding

4.2 Siv cov cuab yeej insulating, hnav cov hnab looj tes insulating, thiab lov tes taw cov khoom tiv thaiv relay ua ntej ua haujlwm yog tias tsim nyog.

4.3 Thaum txuas cov khoom thauj ib ntus, cov keyboards tshwj xeeb thiab fuses yuav tsum tau nruab.

4.4 Thaum lub sij hawm energization ntawm lub thib ob Circuit Court, nyob rau hauv thiaj li yuav tiv thaiv qhov rov qab voltage ntawm lub thib ob sab mus rau lub hauv paus, ntxiv rau disconnecting lub thib ob Circuit Court, thawj fuse yuav tsum tau muab tshem tawm.

4.5 Ua ntej hluav taws xob lossis tiv thaiv qhov ntsuas hluav taws xob ntawm lub voj voog thib ob, tus tub ceev xwm thiab cov neeg ua haujlwm cuam tshuam yuav tsum tau ceeb toom, thiab cov neeg ua haujlwm yuav tsum raug xa mus saib xyuas qhov chaw saib xyuas lub Circuit Court thiab paub meej tias tsis muaj leej twg ua haujlwm ua ntej lub zog.

4.6 Cov neeg ua haujlwm uas kuaj xyuas qhov kev tiv thaiv hluav taws xob thiab lub voj voog thib ob tsis raug tso cai ua haujlwm hloov pauv yam tsis tau tso cai los ntawm cov neeg ua haujlwm hauv lub luag haujlwm.
