Dab tsi yog txoj kev saib xyuas ntawm hloov fais fab fais fab?
1. Khij cov rectification thiab lim dej hauv Circuit Coill. Yog tias lub fuse sab hauv xim dub thiab str-f6454 (NCB21) Kev siv tau Cread80, CE, C827 (qee cov qauv tsis muaj C827) R823, UB222).
2. Tshawb xyuas tias Str-F6454 (4) Pin Sab Nraud Circuit Court yog lub zog hluav taws xob terminal rau kev pib lub zog hluav taws xob, thiab cov kev ntsuas hluav taws xob zoo yog 18.2V. Yog tias qhov hluav taws xob ntawm tus pin tsawg dua 11V thiab tseem nyob ruaj khov, khij cov hluav taws xob hluav taws xob nrog Cheebtsam xws li V801, 18v), VD8003 (22V) raws li tus tseem ceeb; Yog tias muaj kev hloov pauv ntawm LLV ~ L5V, nws qhia tau tias hloov fais fab fais fab tau pib tshee. Tom qab ntawv xyuas seb puas muaj luv luv txoj kev siv luv luv, cov khoom siv lim, thiab hluav taws xob cov chaw ntawm tus kab hloov pauv, tshwj xeeb tshaj yog nyob rau hauv kab ke hauv Circuit Court.
3. Xyuas cov hluav taws xob kev tswj hwm tswj lub voj. Yog tias lub + b voltage maj mam poob ntawm 160v rau xoom ntawm lub zog ntawm lub zog ntawm, tom qab xyuas cov khoom siv ntawm cov kev cai tswj cov voj. Koj tuaj yeem hloov cov Optocoudler N830 ua ntej, thiab tom qab ntawd hloov qhov yuam kev Amplify N831. Nws yog qhov zoo tshaj plaws los kuaj yog R807 yog qhib Circuit Court.
Cov lus qhia: tus schottky diode ako3 yog sab nraud txuas nrog pins (4) thiab (5) ntawm no IC. Thaum lub sij hawm kho tiag tiag, cov diode no tuaj yeem raug rho tawm lossis hloov nrog RU2 RU4, 55295 thiab lwm hom dodes.
