Lub luag haujlwm tseem ceeb ntawm transformer bushing yog kom ua tiav cov khoom siv hluav taws xob sib txuas ntawm sab hauv windings ntawm lub transformer thiab sab nraud Circuit Court, thaum muab kev ruaj ntseg rwb thaiv tsev, kev txhawb nqa txhua yam, thiab kev tiv thaiv kev sib khi. Nws yog ib qho tseem ceeb tshaj plaws ntawm kev hloov pauv, cuam tshuam ncaj qha rau kev nyab xeeb thiab ruaj khov ntawm cov khoom siv.
Kev piav qhia ntxaws txog cov haujlwm tseem ceeb
Kev sib txuas hluav taws xob thiab kev sib kis tam sim no: Raws li qhov tam sim no - nqa cov khoom, lub transformer bushing muaj kev nyab xeeb ua rau cov coj ntawm sab hauv siab - thiab qis -voltage windings mus rau sab nraud ntawm lub tank thiab txuas rau cov kab hluav taws xob sab nraud. Thaum lub sijhawm ua haujlwm ib txwm muaj, nws nqa cov khoom thauj tam sim no rau lub sijhawm txuas ntxiv thiab yuav tsum tiv taus qhov siab tam sim no - tam sim no surges thaum lub sijhawm ua txhaum xws li luv luv circuits.
Rwb thaiv tsev thiab kev rho tawm: Lub bushing yog lub hauv paus thaiv kev tiv thaiv ntawm cov coj thiab lub hauv paus transformer tank, kom ntseeg tau tias muaj hluav taws xob txaus nyob nruab nrab ntawm qhov siab -voltage conductor thiab hauv av los tiv thaiv kev sib tsoo lossis kev sib tsoo. Nws cov rwb thaiv tsev kev ua tau zoo txais ntau cov qauv tsim raws li qib voltage nce, xws li capacitive designs rau uniformly faib hluav taws xob teb.
Mechanical Fixing and Support: Muab cov khoom siv dag zog txaus, nws kho txoj haujlwm ntawm cov coj, tiv thaiv tus neeg xyuas pib nro, cua vibration, seismic rog, thiab kev ua haujlwm kev ntxhov siab, tiv thaiv kev sib cuag tsis zoo lossis kev puas tsuaj vim xoob.
Ib puag ncig sealing ua kom tiav kev sib cais ntawm lub transformer lub internal insulating roj system los ntawm sab nraud ib puag ncig, tiv thaiv cov roj to thiab intrusion ntawm huab cua thiab noo noo, yog li tswj kev rwb thaiv tsev kev ua tau zoo thiab cov khoom siv lifespan. Feem ntau cov bushings raug kaw tag nrho, nrog cov roj sab hauv ncig ntawm nws tus kheej thiab tsis cuam tshuam los ntawm huab cua.
