Lub Circuit Court txhaum ntawm lub twj tso kua mis submersible muaj xws li qhib Circuit Court (uas yog, tsis muaj kev sib txuas ntawm cov kab), thiab muaj to (cov rwb thaiv tsev txheej ntawm cov enameled hlau puas lawm los yog lub kauj yog grounded)
Yuav ua li cas los daws cov kab txhaum? Rau kev qhib Circuit Court, peb tuaj yeem siv lub tshuab multimeter los hloov kho rau Fengming qib, uas yog, qib diode los ntsuas qhov ntsuas tus nqi ntawm txhua pawg coils. Feem ntau, qhov tseem ceeb tsis kam ntawm peb lub twj tso kua mis submersible yog nyob ze rau ib leeg. Yog tsis muaj Resistance, uas yog, lub kauj yog thaiv, uas yog, lub Circuit Court yog tawg.
Muaj lwm hom kev xau. Rau qhov txhaum no, peb yuav tsum siv ib lub 'meter'. Lub 'meter' muaj ob kab. Peb txuas ib qho mus rau ib txheej ntawm cov coils thiab lwm qhov rau cov ntawv hlau, thiab tom qab ntawd tig tus kov ntawm lub ntsuas kom pom Cov kev taw qhia ntawm tus taw tes ntawm lub vijtsam viav vias, yog tias tus taw tes tig mus rau 500, nws txhais tau hais tias lub kauj tsis xau, uas yog qhov qub. Yog hais tias nws hloov mus rau 0, nws txhais tau hais tias lub kauj yog to, thiab nws yuav tsum tau kho.
Los ntawm kev siv txoj kev co lub 'meter' los ntsuas qhov tsis kam ntawm txhua qhov ntawm peb txheej ntawm coils thiab hauv av, nws muaj peev xwm txiav txim seb txoj kab puas zoo los yog phem.
Tsis tas li ntawd, thaum lub twj tso kua mis submersible raug tshem tawm ntawm cov dej, nws yog ib qho tsim nyog yuav tsum tau xyuas seb lub twj tso kua mis lub cev puas raug puas lawm. Seb lub gasket puas. Yog tias muaj teeb meem, nws yuav tsum tau hloov tam sim ntawd kom tsis txhob muaj kev puas tsuaj ntxiv los ntawm cov dej nkag mus rau hauv lub twj tso kua mis tom qab tso tawm.
Yog hais tias nws yog los xyuas lub Circuit Court, ces pib los ntawm lub ntsiab Circuit Court, thiab ces xyuas cov tswj Circuit Court, nws yuav tsum tau kho raws li cov duab kos.
Yog tias koj xav txheeb xyuas qhov txhaum ntawm lub twj tso kua dej nws tus kheej, nws tsis txaus los tso siab rau ib leeg ib leeg. Lub multimeter tuaj yeem ntsuas qhov tsis kam ntawm lub twj tso kua mis lub cev muaj zog winding, tab sis vim tias qhov voltage ntawm lub multimeter nws tus kheej qis heev, nws tsis tuaj yeem ntsuas qhov tseeb seb qhov rwb thaiv tsev ntawm lub twj tso kua mis lub cev muaj zog puas tsim nyog. Rau cov twj submersible, rwb thaiv tsev puas yuav tsum yog ib qho tsis ua hauj lwm.
Txhawm rau txheeb xyuas qhov rwb thaiv tsev ntawm lub cev muaj zog, lub ntsuas hluav taws xob qis qis nrog qhov ntsuas hluav taws xob ntawm 500 volts yog xav tau. Txuas ib kawg ntawm lub megger mus rau lub plhaub ntawm lub twj tso kua mis dej, thiab lwm qhov kawg rau peb windings ntawm lub cev muaj zog (qhov peb windings yuav tsum tau luv luv-circuited ua ntej), thiab ces co lub kov ntawm megger ntawm ib tug. ceev ntawm 120 revolutions ib feeb. Yog tias qhov ntsuas yog tias tus nqi qis dua li tus nqi ib txwm muaj, nws txhais tau tias lub tshuab hluav taws xob ntawm lub twj tso kua mis tau raug puas tsuaj thiab siv tsis tau lawm.
