Tam sim no transformer (CT) yog ib qho cuab yeej hluav taws xob siv los ntsuas qhov hloov pauv tam sim no lossis muab cov teeb liab cais tawm tam sim no. Kev khiav hauj lwm ntawm lub hauv paus ntsiab lus ntawm electromagnetic induction, nws hloov lub siab - magnitude tam sim no mus rau hauv proportionally qis tam sim no, yog li ua kom muaj kev nyab xeeb kev ntsuas thiab tswj los ntawm instrumentation, tiv thaiv cov cuab yeej, los yog relays. Nyob rau hauv lub tshuab fais fab, tam sim no transformers tsis tsuas yog xyuas kom meej ntsuas qhov tseeb tab sis kuj zoo cais high-voltage circuits, yog li tiv thaiv ob qho tib si khoom thiab cov neeg ua hauj lwm.
Raws li lawv cov qauv thiab daim ntawv thov, tam sim no transformers tuaj yeem muab faib ua ntau hom. Nyob rau hauv cov nqe lus ntawm winding qauv, lawv muab faib mus rau hauv toroidal, columnar, thiab split-core hom; ntawm no, toroidal transformers feem ntau yog siv nyob rau hauv lub hwj chim faib systems, columnar transformers yog haum rau siab -voltage ib puag ncig, thiab phua-core transformers pab yooj yim ntawm - site installation thiab txij nkawm. Hais txog daim ntawv thov, lawv tau faib dav rau hauv kev ntsuas -chav kawm thiab kev tiv thaiv- hom chav kawm; yav dhau los ua qhov tseem ceeb ntawm kev ntsuas qhov tseeb, thaum yav tas los hais txog cov lus teb ceev ceev thaum lub sijhawm ua txhaum los xyuas kom muaj kev nyab xeeb ntawm lub zog hluav taws xob.
Tam sim no transformers tuaj yeem muab faib ntxiv raws li cov txheej txheem mounting, ntsuas theem tam sim no, thiab polarity. Piv txwv li, hais txog mounting txoj kev, lawv yuav categorized li busbar-los ntawm hom los yog nto-mounted hom; hais txog cov qib tam sim no, lawv tau muab faib ua qib qis-voltage, nruab nrab-voltage, thiab high- qib voltage; thiab hais txog polarity, lawv txawv raws li pem hauv ntej-polarity lossis thim rov qab-polarity transformers. Hauv kev siv cov tswv yim, xaiv qhov tsim nyog hom transformer tam sim no tseem ceeb heev; nws tsis tsuas cuam tshuam kev ntsuas qhov tseeb tab sis tseem cuam tshuam ncaj qha rau kev ua haujlwm kev nyab xeeb ntawm lub zog hluav taws xob thiab lub neej kev pab cuam ntawm cov khoom siv sib txuas.
