Circuit Breakers Ob qho AIS thiab GIS siv tib yam ntawm lub tank tuag SF6 puffer Circuit Court breaker. Txawm li cas los xij, nrog GIS systems, Hloov ntawm SF6-to-air bushings mounted ntawm lub Circuit Court breaker enclosure, GIS Circuit Court breaker yog txuas ncaj qha mus rau GIS module uas nyob ib sab.
Tam sim no Transformers rau GIS ApplicationsCurrent transformers yog cov cuab yeej uas tau teeb tsa insubstations rau lub hom phiaj ntawm kev hloov cov high-tam sim no los ntawm tus neeg xyuas pib rau hauv cov qauv, sib npaug, uas yog siv rau lub hom phiaj ntawm kev ntsuas, ntsuas, thiab kev tiv thaiv. Installation Qhov Chaw - Tam sim no transformers ntsia nyob rau hauv aGIS system yog ntawm inductive-ntiv nplhaib, thiab tuaj yeem ntsia sab hauv lossis sab nraum GIS enclosure. Metering thiab kev tiv thaiv - yog ua nyob rau hauv lub thib ob winding sab ntawm lub transformer. GIS tus neeg xyuas pib yog ib zaug tig thawj zaug rau chav tsev tam sim no transformer.
Kev txiav txim siab rau tam sim no TransformersFor CTs ntsia rau sab hauv ntawm lub thawv - lawv yuav tsum tau tiv thaiv los ntawm cov hluav taws xob hluav taws xob uas tsim los ntawm cov hluav taws xob hluav taws xob hluav taws xob, txwv tsis pub cov hluav taws xob hloov pauv siab tuaj yeem tshwm sim ntawm cov cua ntsawj ntshab thib ob los ntawm kev sib txuas ua ke. Rau CTs mounted rau sab nraum lub enclosure - lub enclosure nws tus kheej yuav tsum muaj ib tug insulating sib koom, thiab enclosure tam sim no shuntedaround lub CT. Ob qho tib si ntawm GIS kev tsim kho tau dav siv.
Digital Output Signals los ntawm CTs - Analog RelaysAdvanced hom CTs tau tsim los kom txuag tau qhov chaw thiab txo tus nqi ntawm GIS, los ntawm kev tshem tawm cov tub ntxhais sib nqus los yog Rowgowski coil. Cov teeb liab tso zis ntawm cov hom CT units yog nyob rau theem qis, tso cai rau kev hloov pauv tam sim ntawd los ntawm lub kaw lus-mounted ntaus ntawv, mus rau hauv lub teeb liab digital. Thaum lub teeb liab yog digital, Nws tuaj yeem kis tau mus ntev los ntawm kev xaim lossis fiber ntau optic cabling, mus rau kev tswj lossis kev tiv thaiv relays. Ib qhov teeb meem yog, tias ntau qhov kev tiv thaiv relays siv los ntawm cov khoom siv hluav taws xob tam sim no tsis lees txais cov tswv yim digital txawm tias tus relay yuav hloov pauv cov teeb liab analog rau digital, ua ntej ua.
Voltage Transformers Voltage transformers (VTs) siv hauv GIS daim ntawv thov yog hom inductive nrog cov tub ntxhais hlau. Lub VT feem ntau yog ib lub tsev kaw nrog cov roj thaiv hluav taws xob. Installation Option 1 - VT yog tshem tau yooj yim yog li GIS tuaj yeem kuaj qhov hluav taws xob siab yam tsis muaj kev puas tsuaj rau chav tsev.Installation Option 2 - VT yog muab los ntawm kev hloov pauv los yog tshem tawm tus neeg xyuas pib txuas. Thawj winding - tau txais kev txhawb nqa ntawm ib zaj duab xis yas insulating rau hauv SF6.Txawm li cas los tiv thaiv capacitive coupling ntawm transient voltages - VT yuav tsum muaj ib qho hluav taws xob tiv thaiv ntawm thawj thiab theem nrab windings.
