Thaum txhim kho ntau yam khoom siv hauv tsev, feem ntau nws yuav tsum tau tswj hwm thiab txwv lub zog ntawm cov zis tam sim no. Cov khoom siv hluav taws xob ruaj khov nrog ntau yam ntawm cov zis hluav taws xob ntau thiab cov teeb meem hloov kho tau tam sim no yuav pab daws qhov teeb meem no.
Tsim nyog
- - qhov ntsuas hluav taws xob transistor;
- - tam sim no hloov dua siab tshiab.
Cov Lus Qhia
Kauj ruam 1
Yog tias koj npaj siab yuav txo qhov tam sim no ntawm koj tus kheej, tsis tas siv cov khoom siv sib txawv thiab cov kab hluav taws xob, siv cov ntsuas hluav taws xob transistor. Cov cuab yeej yuav pab txwv lossis nce ntxiv rau tam sim no thiab tau txais lub zog xav tau ntawm cov zis.
Kauj ruam 2
Ntawm kev tawm tswv yim ntawm tus neeg tswj hwm zoo li no, koj tuaj yeem muab hluav taws xob tsis ruaj tsis khov mus txog 40 V. Thaum tso tawm ntawm lub cuab yeej, koj yuav tau txais qhov yuav tsum tau muaj tam sim no, thiab koj tuaj yeem tua nws tawm yam tsis tau hloov mus rau lub pob hluav taws xob. Qhov siab tshaj plaws tam sim no xa mus rau lub ntsaws yuav yog los ntawm 10 microamperes mus rau 3 amperes.
Kauj ruam 3
Siv lub zog fais fab transistor qauv KT # 803 ua lub hauv paus rau hauv Circuit Court. Cov cuab yeej siv hauv tsev muaj ntau cov qauv siv piv txwv, piv txwv, txawv teb transistor qauv 2N3055. Ib qho kev ua haujlwm ntawm daim duab txuas hluav taws xob yog kev suav nrog ntawm transistor VT3, uas yuav hloov pauv thiab tswj txoj haujlwm tam sim no tsawg. Cov kev txuas ua ke yuav muab cov taws kub ua kom tsis sib haum raws li qhov kev txwv. Lub hauv paus-emitter yuav tswj cov fais fab transistor VT4.
Kauj ruam 4
Txuas resistor R5 rau cov zis hluav taws xob, thiab lub resistor R6 rau qhov txwv tam sim no. Koj yuav tau txais kev hloov pauv tam sim no.
Kauj ruam 5
Kev lag luam network muag cov hloov pauv npaj txhij txiav tawm tam sim no mus rau qhov yuav tsum tau siv uas muaj zog. Piv txwv li, cov qauv hloov pauv FE No. 1890-AD yog tsim rau AC thiab DC lub hwj chim hluav taws xob nrog lub zaus ntawm 50 Hz. Cov cuab yeej tuaj yeem muab ntsia tsis tuaj yeem lossis ua ib feem ntawm kev siv cov tshuab tsis siv neeg.
Kauj Ruam 6
0-10V LTTJ tus qauv hloov khoom siv tam sim no tso cai rau koj tsis tsuas hloov lub load lub zog, tab sis kuj rau ntawm nws tus kheej xaiv qhov ntau xav tau.
Kauj Ruam 7
Txhim kho txhua tus qauv ntawm cov hloov ua ntej raws li cov qauv txheej txheem hauv kev sib txuas ntawm cov khoom siv thiab txais tam sim no. Koj yuav tau txais cov ntau yam koj xav tau los ntawm 30 microamperes mus rau 3 amperes. Qhov no yuav tso cai rau koj los kho cov kab kev los yog kho cov kev hloov kho tsis siv neeg.
