Hauv transformer: general kev piav qhia thiab daim ntawv thov

Yuav kom ho txhim kho lub kev nyab xeeb tej yam kev mob ntawm hluav taws xob thiab teeb pom kev zoo circuits nyob rau hauv Feem ntau, pom zoo kom siv ntawm ib lub teeb voltage yog ho qis tshaj uas siv nyob rau hauv tus qauv network (220). Feem ntau xws kev pab them nqi kho nyob rau hauv chav qab lawj, chav dej, cellars, thiab lwm yam ntub dej chaw. Rau lub hom phiaj no, qhov thiaj li hu ua halogen lub teeb siv rau hnub tim, uas lub operating voltage yog 12 V siv ib tug ntaus ntawv xws li ib tug hluav taws xob transformer rau powering xws teeb. Qhov no ntaus ntawv muaj peev xwm sawv ntawm transforming lub mains voltage ntawm 220 V 12 V (rau cov pom tau hauj lwm ntawm halogen lub teeb).

Yog hais tias koj saib nyob rau hauv qhov transformer, nws yuav tsum to taub hais tias cov sab nraud ntaus ntawv nws yog heev yooj yim. Nws yog ib tug me me yas los yog hlau box, uas yog tso zis los ntawm cov plaub nyob ntawm tej: ob tug mej zeej (sau tias 220), thiab ob ntsaws (sau tias 12).

Lub hauv paus ntsiab lus ntawm cov lag luam ntawm tej pab kiag li lawm, xws li hluav taws xob transformer, yog yooj yim heev. Dimming yog ua los ntawm thyristor controllers (hu ua dimmers). Cov ntawm lwm yam uas yog los ntawm lub high voltage (tswv yim). Yuav kom ib tug dimmer yuav kev cob cog rua ntawm lub tib lub sij hawm ib tug ntau ntawm pab kiag li lawm xws li hluav taws xob transformers. Lawm, muaj raug circuits incorporating xws kiag li lawm thiab tsis muaj regulators. Nws yog ib qho tseem ceeb kom nco ntsoov lub mob: hluav taws xob transformer yuav tsis khiav tsis muaj load. Nws yog tsim nyog them sai sai kuj mus rau lub hwj chim. Niaj hnub no txoj kev tuam txhab uas muag cov hluav taws xob transformers rau hwj chim los ntawm 60 mus rau 250 watts.

Tus ntaus ntawv - ib tug laub-rub oscillator rau ntawm ib nrab-choj Circuit Court. Lub ob txhais tes ntawm tus choj - qhov no yog transistors. Tus lwm yam ob txhais tes - capacitors. Uas yog vim li cas xws li ib tug choj yog hu ua ib nrab-choj. Nyob rau hauv ib kab pheeb ces kaum yog nkag ib tug voltage uas yog rectified los ntawm ib tug diode choj. Nyob rau hauv lwm yam kab pheeb ces kaum kev cob cog rua load. Rau kev tswj kev khiav haujlwm hauv lub transistor diagonally nyob rau hauv lawv cov saw muaj kev cob cog tawm tswv yim winding ntawm lub transformer. Lub rectified choj voltage yuav them cov capacitor thiab thaum twg lub capacitor voltage nce mus txog cov kev txwv, thiab yuav tsum tsim nyob rau dynistor mem tes txhais tam sim no converter.

Nyob rau hauv xws li ib tug ntaus ntawv raws li ib tug hluav taws xob transformer, muaj ntau ntau ntawm indisputable zoo. Ua ntej, mention yuav tsum tau ua los ntawm me me zuag qhia tag nrho qhov ntev thiab tsis muaj ceeb thawj. Qhov no yuav qhia ib qho zoo heev lub sij hawm mus tsim ib qho kev siv hluav taws xob transformer zoo nyob qhov twg (txawm nyob rau hauv tej thaj chaw deb qhov chaw). Ib txhia niaj hnub teeb pom kev zoo khoom uas hais tias yog yeej tsim siv rau cov halogen lub teeb, twb nyob rau hauv ua ntej muaj ntau yam ua-nyob rau hauv hluav taws xob transformer. Tej schemes tau thov nyob rau hauv lub tsev, rau piv txwv, nyob rau hauv chandeliers ntaus ntawv. Hauv transformers tam sim no teev nyob rau hauv cov rooj tog, xws li tej chaw, los tsim highlights hangers thiab txee.

Tab sis qhov no yog tsis yog txhua txhua qhov kev siv ntawm xws li ib tug ntaus ntawv raws li ib tug hluav taws xob transformer. Piv txwv li, muaj ib co kev txhim kho, uas feem ntau tsis txawm yuav qhib qhov rooj, txawm li cas los, tso cai rau koj los mus tsim ib tug switching fais fab mov ntawm ib tug hluav taws xob transformer (UPS).
