Transformer bushings raug cais raws li lawv cov qib voltage, cov khoom siv, thiab kev siv. Ntawm no yog cov hom tseem ceeb ntawm transformer bushings:
Raws li Voltage Levels
- Tsawg Voltage Bushings (LV Bushings):
Siv rau sab qis-voltage ntawm transformer.
Tsim los rau qhov voltages feem ntau tsawg dua 1 kV.
- High Voltage Bushings (HV Bushings):
Siv rau sab high-voltage ntawm transformer.
Tsim los rau qib siab dua voltage, xws li los ntawm ob peb kV mus rau ntau pua kV.
Raws li Insulating Medium
- Porcelain Bushings:
Ua los ntawm cov plooj (porcelain) muaj zog heev.
Paub txog zoo mechanical thiab hluav taws xob insulating zog.
Feem ntau nyob rau hauv ob qho tib si tsawg thiab high voltage daim ntawv thov.
- Composite Bushings:
Muab cov ntaub ntawv xws li cob, fiberglass, thiab silicone roj hmab.
Lub teeb thiab tiv taus ntau dua rau ib puag ncig yam xws li cov pa phem thiab UV hluav taws xob.
Nce nrov vim lawv durability thiab kev ua tau zoo.
- Resin Impregnated Paper (RIP) Bushings:
Siv daim ntawv impregnated nrog cob ua cov khoom tseem ceeb insulating.
Muab cov hluav taws xob rwb thaiv tsev zoo heev thiab feem ntau siv rau hauv cov ntawv siv hluav taws xob siab.
- Resin Bonded Paper (RBP) Bushings:
Zoo ib yam li RIP tab sis nrog cov txheej txheem kev thov sib txawv.
Kuj siv nyob rau hauv high voltage daim ntaub ntawv, muab zoo hluav taws xob thiab txhua yam khoom.
- Roj-Impregnated Paper (OIP) Bushings:
Siv ntawv rwb thaiv tsev impregnated nrog roj.
Feem ntau nyob rau hauv high voltage kev siv.
Yuav tsum tau kho ntau dua vim muaj roj.
Raws li Kev Tsim Kho
- Khoom-hom Bushings:
Ua los ntawm cov khoom siv rwb thaiv tsev xws li epoxy resin lossis porcelain.
Yooj yim tsim thiab dav siv nyob rau hauv ntau yam kev siv.
- Capacitor-Type Bushings:
Muaj cov txheej txheem capacitive nyob rau hauv lub rwb thaiv tsev los tswj cov hluav taws xob xa hluav taws xob.
Siv nyob rau hauv high voltage daim ntawv thov kom txo hluav taws xob kev nyuaj siab thiab txhim kho kev ua tau zoo.
Raws li Daim Ntawv Thov
- Sab hauv Bushings:
Tsim los siv sab hauv tsev, tiv thaiv los ntawm ib puag ncig cov ntsiab lus.
Feem ntau hauv kev lag luam thiab kev lag luam kev teeb tsa.
- Sab nraum zoov Bushings:
Tsim los rau kev siv sab nraum zoov, muaj peev xwm tiv taus ib puag ncig xws li nag, plua plav, thiab UV raug.
Feem ntau nyob rau hauv substations thiab lwm qhov chaw sab nraum zoov.
Hom tshwj xeeb
- Draw-Lead Bushings:
Tso cai rau kev hloov pauv yooj yim thiab txij nkawm ntawm kev sib txuas sab hauv.
Siv rau hauv cov ntawv thov tshwj xeeb uas yuav tsum tau saib xyuas tas li.
- Gas-Insulated Bushings:
Siv cov roj (feem ntau yog SF6) ua qhov nruab nrab insulating.
Feem ntau hauv gas-insulated switchgear (GIS) thiab lwm yam kev siv tshwj xeeb.
Xaus
Kev xaiv ntawm transformer bushing nyob ntawm seb cov kev cai tshwj xeeb ntawm daim ntawv thov, nrog rau qib voltage, ib puag ncig, kev tu ncua kev xav tau, thiab cov nqi xav tau. Txhua hom bushing muaj nws qhov zoo thiab haum rau cov kev siv tshwj xeeb hauv kev faib hluav taws xob thiab kev sib kis network.
