Yuav ua li cas ib tug Transformer Bushing ua hauj lwm
Internal qauv ntawm ib tug transformer bushing
Cov qauv sab hauv ntawm lub transformer bushing feem ntau muaj xws li: lub hauv paus rau kev ua tam sim no, "lub siab" muab rwb thaiv tsev, thiab kev txhawb nqa sab nraud rau kev sib txuas thiab kho. Lub luag haujlwm tseem ceeb yog tso cai rau lub siab -voltage conductor kom nyab xeeb "xov" hauv av transformer tank.
ua hauj lwm hauv paus ntsiab lus ntawm ib tug transformer bushing
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm bushing yog raws li nram no:
Yog hais tias koj xav txog lub transformer raws li ib tug loj "hluav taws xob kettle," nws muaj high -voltage hluav taws xob, thiab lub plhaub sab nrauv yog grounded hlau (zero peev xwm).
Lub luag haujlwm tseem ceeb ntawm bushing yog kom muaj kev nyab xeeb coj lub siab - hluav taws xob hluav taws xob los ntawm "kho" mus rau sab nraud uas siv "straw," tsis muaj qhov to.
Qhov kev sib tw tseem ceeb yog: yog tias lub siab- hluav taws xob xaim ncaj qha dhau los ntawm lub qhov hauv lub plhaub hlau, ntawm ntug ntawm lub qhov, qhov siab - hluav taws xob hluav taws xob yuav ua rau "dhau" mus rau lub plhaub hauv av, ua rau muaj "hluav taws xob" (xws li, hluav taws xob qhov chaw concentration, ua rau tawg).
Lub bushing yog zoo li "ntse thiab robust multi-txheej straw," daws qhov teeb meem no nrog peb hauv qab no - txheej txheej:
Sab hauv txheej (voltage equalization txheej): Dissipating siab.
Qhov no yog txheej txheem ntse tshaj plaws. Nws tsis yog yooj yim yas, tab sis ntau txheej ntawm "insulating ntawv sandwiching hlau ntawv" qhwv nyob ib ncig ntawm lub conductive pas nrig, tsim ib tug capacitive voltage divider qauv. Nws sib npaug faib qhov sib txawv loj ntawm qhov sib txawv ntawm "sab hauv" thiab "sab nraud" ntawm lub transformer (piv txwv li, 220,000 volts) mus rau ntau pua lub zog me me. Zoo li hloov lub pob zeb ntxhab mus rau hauv ib qho yooj yim staircase, hluav taws xob "siab" yog sib npaug, tiv thaiv nws los ntawm kev tawg ntawm ib qho chaw.
Nruab nrab Txheej (Insulation thiab Sealing Layer): Sealing thiab Txhawb nqa
Qhov no yog ib qho khoom siv hluav taws xob zoo los yog cov khoom siv sib xyaw ua ke uas kaw thiab kaw "sab hauv txheej." Nws ua haujlwm rau ob lub hom phiaj: thawj zaug, kev rwb thaiv tsev tsis muaj tseeb, kom ntseeg tau tias qhov siab - hluav taws xob hluav taws xob yog ruaj khov rau hauv; thib ob, txhua yam kev txhawb nqa thiab kev sib khi, zoo li lub raj mis stopper, ruaj khov kho nws mus rau lub transformer casing kom tiv thaiv kom tsis txhob ntws ntawm cov roj insulating sab hauv.
Txheej Txheej Txheej (Cov Txheej Txheem Tiv Thaiv): Tiv Thaiv Sab Nraud Ib puag ncig
Qhov chaw raug huab cua muaj qhov tshwj xeeb tsim nto (xws li lub kaus mom lub kaus mom lossis cov roj hmab silicone) los tiv thaiv los nag, av, thiab flashover. Zoo li txheej txheej straw nrog cov txheej txheem dej tsis zoo, nws ua kom lub zog tam sim no tsis khiav raws phab ntsa sab nrauv thaum nws los nag los yog qias neeg.
Khoom Description
40.5kV bushing insulatoryog haum rau peb -theem AC systems fais fab chaw nres tsheb thiab substation faib khoom nrog ib tug rated voltage ntawm 40.5kV thiab ib tug zaus ntawm 50 ~ 60Hz. Nws yog siv los tso cai rau cov khoom siv hluav taws xob kom dhau los ntawm kev faib tawm, phab ntsa, lossis lwm yam khoom siv hauv av, thiab ua haujlwm raws li kev txhawb nqa rwb thaiv tsev thiab kev sib txuas ruaj khov ntawm cov khoom siv sab nraud (busbars).
