Yuav ua li cas xaiv qhov tam sim no transformer?

Tam sim no transformers (CTs) thiab voltage transformers (VTs), tseem hu ua lub peev xwm hloov pauv (PTs), yog cov khoom tseem ceeb hauv kev tsim ntau lub zog, nrog rau kev ntsuas hluav taws xob, kev tiv thaiv relays, thiab kev saib xyuas hluav taws xob zoo. Xaiv txoj cai transformer yog qhov tseem ceeb los xyuas kom meej qhov tseeb thiab kev ntseeg siab ntawm cov tshuab no. Hauv tsab xov xwm no, peb yuav tshawb txog cov ntsiab lus tseem ceeb los txiav txim siab thaum xaiv CTS thiab VTS.

• Chav Kawm raug: Thawj qhov kev xav tau los txiav txim siab yog chav kawm raug ntawm lub tshuab hloov pauv. Qhov no txiav txim siab theem ntawm qhov tseeb uas lub transformer tuaj yeem muab tau raws li kev ua haujlwm sib txawv. Lub International Electrotechnical Commission (IEC) tau txhais ntau qhov kev kawm raug, xws li {{0}}.1 txog 10, nrog 0.1 yog qhov tseeb tshaj plaws. Cov chav kawm raug txiav txim siab los ntawm CT lossis VT lub peev xwm los tswj cov qib kev ua yuam kev hauv cov teeb liab tso tawm raws li cov xwm txheej tau teev tseg.
• Ntau zaus: Qhov tseem ceeb tom ntej yuav xav txog yog qhov ntau zaus ntawm daim ntawv thov. Qhov no yuav txiav txim siab cov khoom tseem ceeb thiab cov qauv winding uas yuav siv tau. CTs thiab VTs tsim los rau cov ntawv thov tsawg zaus feem ntau muaj cov cores ua los ntawm cov laminated silicon steel, thaum cov uas tsim los rau cov ntawv thov ntau zaus yuav muaj cov cores ua los ntawm ferrite lossis hmoov hlau. Tsis tas li ntawd, cov qauv winding yuav tsum tau tsim los txo cov kab mob parasitic capacitance thiab inductance.
• Ratio thiab Burden: Qhov piv thiab lub nra ntawm lub transformer kuj tseem ceeb heev. Qhov sib piv txiav txim siab txog kev sib raug zoo ntawm cov thawj thiab theem nrab tam sim no lossis voltages, thaum lub nra hnyav txiav txim siab qhov siab tshaj plaws uas lub tshuab hloov pauv tuaj yeem daws yam tsis muaj kev cuam tshuam cov teeb liab tawm. Qhov piv thiab lub nra hnyav yuav tsum tau ua tib zoo xaiv los xyuas kom meej tias lub tshuab hloov pauv tuaj yeem muab cov kev ntsuas raug thiab txhim khu kev qha nyob rau hauv txhua qhov kev ua haujlwm.
• Rwb thaiv tsev Level: Cov theem rwb thaiv tsev ntawm lub transformer yog lwm qhov tseem ceeb rau kev txiav txim siab. Qhov no txiav txim siab qhov siab tshaj plaws voltage uas lub transformer tuaj yeem tiv taus yam tsis muaj kev puas tsuaj. Cov qib rwb thaiv tsev yuav tsum raug xaiv raws li qhov siab tshaj qhov system voltage thiab qhov kev cia siab ntawm overvoltage tej yam kev mob.
• Environmental Conditions: Qhov kawg yam uas yuav tsum xav txog yog ib puag ncig tej yam kev mob uas lub transformer yuav raug rau. Qhov no suav nrog yam xws li kub, av noo, qhov siab, thiab kev co. CTs thiab VTs tsim rau sab nraum zoov lossis hnyav ib puag ncig yuav tsum muaj peev xwm tiv taus qhov kub thiab txias, noo noo, thiab lwm yam kev ntxhov siab ib puag ncig.

Hauv kev xaus, xaiv txoj cai CT lossis VT yog qhov tseem ceeb los xyuas kom meej qhov tseeb thiab kev ntseeg siab ntawm cov tshuab fais fab. Cov kws kho tsheb yuav tsum xav txog yam xws li cov chav kawm raug, qhov ntau zaus, qhov sib piv thiab lub nra, qib rwb thaiv tsev, thiab ib puag ncig ib puag ncig thaum xaiv lub transformer rau lawv daim ntawv thov. Los ntawm kev ua tib zoo soj ntsuam cov xwm txheej no, engineers tuaj yeem xaiv txoj cai transformer rau lawv cov kev xav tau tshwj xeeb thiab txhim kho kev ua haujlwm ntawm lawv lub zog hluav taws xob.Yog xav paub ntxiv, thov hu rau peb ntawmsales@xfullstar.com
