Muab cais nyob ib leegtransformeryog ib qho khoom siv hluav taws xob muaj kev nyab xeeb heev, feem ntau yog siv rau kev kho tshuab, kev tiv thaiv, kev tiv thaiv xob laim thiab lim. Tus tswj transformer yog siv los hloov qhov chaw ntawm AC voltage thiab yog ua los ntawm cov tub ntxhais hlau thiab coil hlau. Nws tuaj yeem tsis tsuas yog hloov qhov voltage ntawm lub alternating tam sim no, tab sis kuj hloov lub impedance, thiab hloov tam sim no thaum nws tsis tshaj lub zog tsim. Peb-theem reactor yog siv nyob rau hauv series nrog lub inlet thiab qhov hluav taws xob terminals ntawm lub zaus converter, raws li lub inlet thiab qhov hluav taws xob reactors ntawm lub zaus converter, uas yuav txo tau cov harmonics generated thaum lub zaus converter ua hauj lwm. Ib tug transformer nrog hluav taws xob cais ntawm cov input winding thiab cov zis winding. Kev rho tawm transformer yog siv los tiv thaiv kev sib chwv lub cev nyob rau tib lub sijhawm. Kev rho tawm transformer yog siv los cais cov tam sim no ntawm thawj theem nrab winding coil. Vim hais tias kev rho tawm transformer yog 1/1 transformer, nws lub luag haujlwm yog kev sib cais muaj kev nyab xeeb. Txhawm rau kom koj muaj kev nkag siab ntau ntxiv ntawm kev sib cais transformer, cia peb saib ze dua ntawm txoj cai ua haujlwm ntawm transformer.
1. Lub hauv paus ntsiab lus yog tib yam li cov transformer zoo tib yam. Siv electromagnetic induction. Kev rho tawm transformer feem ntau yog hais txog 1: 1 transformer. Txuas los ntawm theem nrab dissonance. Tsis muaj peev xwm sib txawv ntawm ib qho xov tooj thib ob thiab hauv av. Kev nyab xeeb siv. Feem ntau siv los ua ib qho khoom siv hluav taws xob tu.
2. Kev rho tawm transformers tsis yog tag nrho 1: 1 transformers. Nws tseem yog lub zog siv rau kev tswj cov transformers thiab cov khoom siv raj. Xws li tube amplifier, raj xov tooj cua thiab oscilloscope, tshuab dhos tswj transformer thiab lwm yam khoom siv fais fab yog nws. Piv txwv li, txhawm rau kom muaj kev nyab xeeb ntawm cov xim TV, 1: 1 cais transformers feem ntau yog siv. Dav dav siv, kuj siv rau hauv cov cua txias.
3. cov lag luam circuits. Txhawm rau kom tsis txhob muaj kev cuam tshuam ib puag ncig no, thawj zaug thiab theem nrab windings ntawm kev sib cais transformer feem ntau muab tso rau ntawm ib sab sib txawv kom txo tau qhov capacitance ntawm kev loj hlob ntawm ob. Tseem muaj cov kev tshawb fawb siv thawj thiab theem nrab winding concentric qhov chaw, tab sis ntxiv electrostatic shielding ntawm windings, thiaj li yuav tau txais kev tiv thaiv kev cuam tshuam.
4, electrostatic shielding yog rau nruab ib daim ntawv uas tsis yog-kaw tooj liab los yog tsis-magnetic daim ntawv ntawm cov thawj thiab thib ob windings, hu ua lub shielding txheej. Daim ntawv tooj liab lossis ntawv tsis-permeable txuas nrog lub vaj tsev los ntawm cov hlau. Qee lub sij hawm txhawm rau txhawm rau tiv thaiv zoo dua, lub npog thaiv npog kuj tau nruab rau ntawm tag nrho cov hloov pauv. Cov hlau lead tawm davhlau ya nyob twg ntawm lub winding kuj yog shielded los tiv thaiv lwm yam sab nraud electromagnetic cuam tshuam. Nyob rau hauv txoj kev no, nws tsuas yog tsim nyog kom paub qhov sib nqus coupling ntawm thawj winding thiab theem nrab winding, thiab qhov sib npaug faib capacitance ntawm qhov thib ob winding yog tsawg dua 0.01pf, uas zoo heev txo cov capacitance tam sim no ntawm lub thawj winding thiab theem nrab winding, thiab zoo tswj cov kev cuam tshuam ntau yam ntawm lub hwj chim mov thiab lwm yam circuits.
