Qhov sib txawv ntawm HVCT thiab HVCT hauv cov qauv thiab daim ntawv thov feem ntau yog qhia hauv cov hauv qab no:
I. Cov qauv sib txawv
Rwb thaiv tsev
High voltage tam sim no transformer (HPCT): HPCT yuav tsum tau tiv taus high voltage, feem ntau yog roj ntawv rwb thaiv tsev, SF6 gas rwb thaiv tsev los yog ceramic vaj tse, los xyuas kom meej uniform faib ntawm hluav taws xob teb thiab siab rwb thaiv tsev zog. Piv txwv li, 220kV system, siab -voltage transformer tuaj yeem txhim kho qhov hluav taws xob zoo nrog cov qauv hluav taws xob sib npaug.
Tsawg voltage tam sim no transformers: Lawv muaj tsawg voltage theem, feem ntau yog insulated los ntawm resin txhaj, yog compact nyob rau hauv cov qauv thiab me me loj. Piv txwv li, lub tsev nyob ntawm qis-voltage transformers hauv qab 0.66kV feem ntau yog ua los ntawm siab - cuam tshuam nplaim hluav taws- cov khoom siv ABS thiab cov khoom siv txhawb nqa perforation.
Plhaub thiab ntim
High voltage tam sim no transformer: los xyuas kom meej rwb thaiv tsev deb thiab tshav kub dissipation, nws ntim kuj loj, siv porcelain tes tsho thiab lwm yam high voltage resistant cov ntaub ntawv. Transformers ntawm 110kV thiab saum toj no, piv txwv li, tej zaum yuav muaj tag nrho cov hlau casings.
Tsawg voltage tam sim no transformer: qauv yooj yim, compact compact resin encapsulation, txo ntim, yooj yim rau nruab. Piv txwv li, lub txee tsis muaj siab muaj CT peb- theem kev tsim qauv nrog qhov ntawm 20mm lossis 35mm, uas txuag tau ntau qhov chaw.
Txheej txheem tsim
High voltage tam sim no transformer: muaj peev xwm txais yuav ib tug capacitive voltage vaj huam sib luag qauv los yog doublecore tsim kom tau raws li kev ntsuas thiab kev tiv thaiv raws. Piv txwv li, cov tub ntxhais hlau siv rau kev ntsuas tau yooj yim saturated thaum lub sij hawm ib qho - ib sab luv luv Circuit Court los txwv qhov thib ob tam sim no, thaum cov tub ntxhais hlau siv rau kev tiv thaiv tseem tsis tau saturated thaum lub sij hawm luv luv los xyuas kom meej qhov sib npaug tam sim no.
Tsawg voltage tam sim no transformer: nrog kev lag luam, installation yooj yim raws li lub ntsiab, txheej txheem yooj yim. Piv txwv li, qee qhov qis -voltage transformers muaj ob npaug - winding qauv, nrog rau ib qho winding rau ntsuas (5A cov zis) thiab lwm qhov winding rau telemetry (0-20mA tso zis).
II. Qhov sib txawv ntawm daim ntawv thov
Daim ntawv thov scenarios
High voltage tam sim no transformer: dav siv nyob rau hauv 1kV rau 220kV fais fab system, xws li substation kis kab kev ntsuas, relay tiv thaiv, rwb thaiv tsev xyuas. Piv txwv li, 10kV thiab 220kV systems yog cov feem ntau daim ntawv thov scenarios, nrog rau tus qauv tso zis nqi ntawm 5A los yog 1A rau theem ob.
Tsawg voltage tam sim no transformer: feem ntau yog siv rau alternating tam sim no Circuit Court hauv qab no 0.66kV, xws li hluav taws xob lub zog ntsuas, industrial tis saib xyuas, tiv thaiv lub cev muaj zog, thiab lwm yam.
High voltage CT
Cov kev xav tau ua haujlwm
High voltage tam sim no transformer: yuav tsum tau ua kom tau raws li qhov yuav tsum tau ntawm high precision ntsuas thiab txhim khu kev qha relay tiv thaiv. Piv txwv li, kev tiv thaiv kev hloov pauv yuav tsum ua kom qhov tseeb ntawm 10 feem pua ntawm qhov siab tshaj plaws luv luv -circuit tam sim no (20 mus rau 30 npaug ntawm qhov ntsuas tam sim no), thiab 10 feem pua kev ua yuam kev nkhaus yog qhov tseem ceeb parameter.
Tsawg voltage tam sim no transformer: ntau dua qhov tseem ceeb ntawm tus nqi -kev ua tau zoo thiab kev yooj yim installation. Piv txwv li, qee qhov qis -voltage transformers txhawb kev txhim kho perforation yam tsis tau tshem tawm cov thawj busbar, zoo heev txo cov nqi zog thiab cov khoom siv ntawm kev kho dua tshiab.
Load thiab yuam kev yam ntxwv
High voltage tam sim no transformer: theem nrab load muaj kev cuam tshuam zoo ntawm transformer yuam kev thiab yuav tsum tau sib phim nrog lub peev xwm ntsuas. Piv txwv li, lub peev xwm ntsuas ntawm tib lub tshuab hloov pauv tuaj yeem sib txawv ntawm qib sib txawv (piv txwv li . 0.5, 10P qib).
Tsawg voltage tam sim no transformer: Load yuav tsum tau so, tab sis kom tiv thaiv overheating xwm txheej vim tsis zoo kev sib cuag ntawm lub ntsiab connector. Piv txwv li, qhov ntev - lub sijhawm ua haujlwm tam sim no yuav tsum tsis pub tshaj 1.1 npaug ntawm tus nqi ntsuas thiab 1.2 npaug ntawm qhov tso cai siv rau lub sijhawm luv luv (txog 1 teev).
III. Cov xwm txheej sib piv
High voltage vaj tse: LZZB series tam sim no transformer yog haum rau 110kV systems. Nws yog tus cwj pwm los ntawm cov roj- ntawv rwb thaiv tsev thiab dual- tus qauv tsim, ntsuas cov chav kawm raug yog 0.2, chav kawm tiv thaiv yog 10P20, ua tau raws li qhov yuav tsum tau muaj kev ntsuas siab thiab kev tiv thaiv sai.
Tsis tshua muaj hluav taws xob: AKH-0.66K series ntawm qhib tam sim no transformers rau kev lag luam hauv nroog fais fab kev kho dua tshiab, txhawb kev teeb tsa tsis muaj kev cuam tshuam. Nrog rau cov zis thib ob ntawm 5A lossis 0-20mA thiab qhov tseeb ntawm 0.5S, nws ua ke nrog kev ntsuas ntsuas thiab telemetry.
Cov ntsiab lus
High voltage tam sim no transformer (HVCT) muaj zog rwb thaiv tsev siab, complex qauv thiab meej tiv thaiv raws li nws cov tub ntxhais. Tsawg voltage tam sim no transformer muaj qhov zoo ntawm kev lag luam, yooj thiab yooj yim installation. Nws yog dav siv nyob rau hauv tsawg voltage tis. Muaj qhov sib txawv hauv kev rwb thaiv tsev tsim, ntim tswj, ua haujlwm kom pom tseeb thiab tswj kev thauj khoom. Kev xaiv yuav tsum yog raws li qhov tseeb voltage theem thiab daim ntawv thov.
