Lub cev muaj zog, lub zog loj ntawm lub cev muaj zog winding grounding txhaum tshuaj ntsuam thiab kho, nrog kev ua haujlwm siab, txuag hluav taws xob, suab nrov me me, lub teeb me me, lub teeb yuag, kev ntseeg tau, yooj yim txhim kho thiab txij nkawm, thiab lwm yam Txij li thaum muab tso rau hauv lub lag luam tau ua haujlwm ib txwm, tab sis hauv Lub Kaum Ob Hlis kawg, hauv kev ua haujlwm ntawm lub cev muaj zog hauv kev tiv thaiv kev tiv thaiv, kev soj ntsuam pom tau tias lub cev muaj zog stator winding grounding teeb liab, ua ntej rooj tuav lub rooj ntsuas cov kab hluav taws xob thiab hluav taws xob rwb thaiv tsev, pom qhov xwm txheej tom qab, tom qab peb tau txais daim ntawv ceeb toom, lub cev muaj zog lub thawv kom daws tau. cable sib koom ua ke, ntsig txog, ntsuas ntawm cable thiab lub cev muaj zog siv 2500 v megohmmeter, ntsuas lub cev muaj zog rwb thaiv tsev mus rau hauv av yog 0.5 M Ω, cable yog 3500 M Ω, nws tuaj yeem txiav txim siab rau lub cev muaj zog stator winding grounding.
Peb paub tias qhov pib txhaum ntawm lub cev winding tuaj yeem tshwm sim hauv cov xwm txheej hauv qab no:
1. Lub sijhawm ntev dhau mus ntawm lub cev muaj zog thiab lub rwb thaiv tsev laus thiab kev tiv thaiv tsis zoo ua rau rwb thaiv tsev puas ntsoog rau hauv av;
2, xaim hluav taws xob xaim overvoltage lossis kev ua haujlwm overvoltage sib tshooj rwb thaiv tsev;
3. Thaum lub tshuab hluav taws xob synchronous dheev txiav tawm qhov sib txuas ntawm lub siab zoo, qhov ntsuas hluav taws xob siab hluav taws xob yuav tsim tawm;
4. Vim tias muaj cov plua plav conductive, qhov nkag ntawm qhov chaw tiaj yuav tsum raug txo qis, ua rau tawg lossis flashover rau hauv av;
5, qhov cua lub puab tsaig groove gasket, ntiv tes hniav nias phaj qhib vuam lossis rivet kev so, hlau tub ntxhais overpressing tsis yog nruj, txhawm rau hniav thiab khoov hniav nias phaj phaj scraping thiab sib tsoo coil rwb thaiv tsev, uas ua rau winding grounding txhaum;
6. Lub rwb thaiv tsev ntawm kev ntog zoo ntawm cov hluav taws xob asynchronous lub hnub nyoog lub cev thiab cov ntawv cog lus, feem ntau vibrates, uas ua rau rwb thaiv kev puas tsuaj ua rau tawg rau hauv av hauv kev pib nquag thiab nres ntawm lub cev muaj zog;
7, vim yog lub luv luv ntawm lub kauj vuam hluav taws xob rwb thaiv tsev, ua rau muaj kev txhaum rau hauv av.
