Induction transformer (Instrument Transformer) yog ib hom tshwj xeeb ntawm transformer siv los ntsuas, saib xyuas thiab tiv thaiv tam sim no thiab voltage hauv lub zog hluav taws xob. Lawv ua lub luag haujlwm tseem ceeb hauv cov tshuab hluav taws xob, pab xa cov cim ntsuas kom raug rau kev saib xyuas, tswj thiab tiv thaiv kev ua haujlwm.
Induction transformers muaj ob hom: Tam sim no Transformer (CT) thiab VoltageHloov pauv(VT).
Yuav ua li cas ib tug tam sim no transformer (CT) ua hauj lwm: tam sim no transformers yog siv los ntsuas loj tam sim no nyob rau hauv lub hwj chim systems, feem ntau yuav txo tau siab tam sim no mus rau ib tug ntau yam haum rau ntsuas ntsuas. Nov yog nws ua haujlwm li cas:
Primary Coil: Thawj kauj ntawm lub transformer tam sim no xa cov tam sim no siab (feem ntau pua mus rau kaum tawm txhiab amps) rau hauv lub transformer.
Secondary coil: Lub ntsiab kauj yog nyob ib puag ncig los ntawm lub kauj thib ob, thiab tus naj npawb ntawm cov lem nyob rau hauv ob kauj ruam yog me me. Qhov kev tsim kho no ua rau muaj kev hloov pauv tam sim no uas hloov siab tam sim no mus rau qhov tsis tshua muaj tam sim no.
Sib nqus coupling: Tam sim no nyob rau hauv thawj kauj induces tam sim no nyob rau hauv lub thib ob kauj nyob rau hauv qhov kev txiav txim ntawm magnetic teb. Vim qhov kev faib ua feem ntawm coil tig, qhov tam sim no raug txo.
Cov zis tam sim no ntawm tam sim no transformer yog proportional rau tam sim no ntawm lub ntsiab coil. Nws feem ntau tso tawm cov qauv me me tam sim no, xws li 5A lossis 1A, txhawm rau pab txhawb kev sib txuas rau cov cuab yeej ntsuas lossis cov cuab yeej tiv thaiv.
Ua hauj lwm hauv paus ntsiab lus ntawm voltage transformer (VT): Voltage transformer yog siv los ntsuas high voltage nyob rau hauv lub hwj chim system thiab txo cov high voltage mus rau ib tug ntau yam kev nyab xeeb. Nov yog nws ua haujlwm li cas:
Main winding: Lub ntsiab winding ntawm voltage transformer yog txuas nrog rau sab voltage siab thiab tau txais high voltage signals.
Secondary winding: Tus naj npawb ntawm cov lem nyob rau hauv lub thib ob winding yog me me, cia lub high voltage ntawm thawj winding yuav tsum tau hloov mus rau hauv ib tug qis voltage.
Sib nqus coupling: Lub teeb liab hluav taws xob siab yog induced mus rau hauv qhov thib ob winding nyob rau hauv qhov kev txiav txim ntawm lub magnetic teb, yog li ua tiav voltage hloov dua siab tshiab.
Cov zis voltage ntawm lub voltage transformer yog proportional rau qhov voltage ntawm lub ntsiab winding. Nws feem ntau outputs tus qauv me me voltage, xws li 110V lossis 220V, los pab txhawb kev sib txuas rau cov cuab yeej ntsuas lossis cov cuab yeej tiv thaiv.
