Tam sim no Transformer vs Voltage Transformer (Tsev Muaj Peev Xwm Transformer)
A transformer yog ib yam khoom uas hloov hluav taws xob los ntawm ib lub voj voog mus rau lwm qhov siv electromagnetic induction los ntawm inductively coupled conductors, kuj hu ua transformer's coils. Raws li tus naj npawb ntawm kev tig nyob rau hauv lub coil thib ob, lub zog hluav taws xob thiab qhov cuam tshuam tam sim no raug cuam tshuam rau hauv lub kauj thib ob. Nws yog siv los tswj cov tam sim no thiab li no qhov voltage nyob rau hauv lub thib ob Circuit Court.
Nyob ntawm cov zis tseem ceeb hauv cov kauj theem ob (tam sim no / voltage), transformer hu ua voltage (muaj peev xwm) transformer lossis tam sim no transformer. Voltage transformers thiab tam sim no transformers yog tsuas yog siv nyob rau hauv instrumentation li no collectively hu ua ntsuas transformers. Nws lwm yam kev siv yog lub zog tiv thaiv thiab tswj.
Ntau txog Voltage (Tswj Muaj Peev Xwm) Transformer
A transformer yog ib qho cuab yeej siv los nce lossis txo qhov voltage ntawm lub kaw lus, ua kom lub zog poob qis tsawg. Lub transformer siv los ua kom qhov voltage yog hu ua step-up transformer, thiab ib tug transformer siv los txo qhov voltage yog hu ua kauj ruam down transformers. Cov zis voltage ntawm lub peev xwm transformer yog proportional rau tus naj npawb ntawm turns nyob rau hauv lub thib ob kauj, uas yog ib kauj ruam down transformer.
Xav tias hauv thawj thiab thib ob coils, tus lej hloov pauv yog NP & NS, thiab qhov voltages yog VP & VS. Tom qab ntawd qhov voltage hauv qhov thib ob tuaj yeem tau txais los ntawm VS / VP=NS / NP.
Muaj peev xwm hloov pauv tau siv rau hauv kev ntsuas, kom tau txais qhov tseeb qhov tso tawm hluav taws xob nrog qhov muaj peev xwm tswj tau qhov sib txawv thoob plaws lub nra. Feem ntau qhov nruab nrab ntawm qhov muaj peev xwm hloov pauv tau ntsuas rau 69 V lossis 120 V rau qhov muab ntsuas thawj qhov hluav taws xob, tsim los ua kom sib haum nrog cov kev ntaus nqi ntawm kev tiv thaiv relays.
Ntau txog Tam Sim No Transformer
A tam sim no transformer yog ib tug transformer tsim los muab cov theem nrab tam sim no proportional rau tam sim no ntws nyob rau hauv nws thawj kauj. Tam sim no transformers feem ntau yog siv rau hauv kev ntsuas cov cuab yeej thiab kev tiv thaiv relays siv nyob rau hauv cov hluav taws xob hluav taws xob tes hauj lwm, qhov chaw uas lawv tso cai ntsuas qhov loj tam sim no yam xyuam xim, uas yog feem ntau nrog high voltages. Tam sim no transformer muaj kev ruaj ntseg cais qhov ntsuas thiab tswj circuitry hauv lub ntsuas los ntawm high voltages uas feem ntau muaj nyob rau hauv lub hwj chim kis circuits.
tam sim no transformers feem ntau muaj xws li ib tug thawj tig thiab ib tug zoo-insulated toroidal theem nrab nrog ntau yam tig. Tam sim no nyob rau hauv theem nrab tuaj yeem tau los ntawm Is/IP=NS/NP. Tam sim no transformers feem ntau yog qhia los ntawm qhov tam sim no piv ntawm thawj mus rau theem nrab. Kev ceev faj yuav tsum tau ua kom tsis txhob cuam tshuam lub voj voog thib ob thaum lub sijhawm tam sim no ntws los ntawm lub hauv paus, vim tias qhov hluav taws xob loj yog induced nyob rau hauv theem ob.
Dab tsi yog qhov txawv ntawm Tam sim no Transformer thiab Voltage Transformer (muaj peev xwm Transformer) ?
• Muaj peev xwm transformers txo qhov voltage nrog qhov nce ntawm tam sim no hauv theem nrab, thaum tam sim no transformers txo qhov tam sim no nrog qhov nce ntawm qhov voltage.
• Lub peev xwm hloov pauv tau siv los ua cov ntsuas hluav taws xob siab thiab cov voltmeters zoo tib yam. Tam sim no transformers yog siv rau qhov chaw ntawm cov ammeters zoo tib yam, los ntsuas qhov muaj nuj nqis ntawm cov tam sim no nyob rau hauv high voltage fais fab kev thov.
• Hauv cov transformers muaj peev xwm, thawj yuav muaj ob peb windings, tab sis nyob rau hauv tam sim no transformer thawj feem ntau muaj ib tug tig.
• Hauv peb theem hluav taws xob xa mus, rau kev ntsuas hauv tib kab, peb lub tshuab hloov tam sim no yuav tsum tau siv, thaum tsuas yog ib lub peev xwm hloov pauv tau txaus.
