Kho cov lus qhia rau cov khoom siv hlawv cov khoom hauv kev sib tw ntawm kev tiv thaiv ntau yam
Nws yog ib txwm muaj rau cov kev tiv thaiv ntau ntawm cov ntau ntawm kev hlawv tawm vim tsis muaj kev xaiv tsis raug.
Noj cov r × 1 thaj tsam ntawm U-10 puv ua piv txwv, nws cov kev yooj yim tau qhia hauv daim duab 5-22.
Ntawm no, R5 yog lub resistance patentiometer, R16 yog lub shunt deistor rau r × 1 ntau yam, thiab tus nqi nruab nrab ntawm ntau npaum li cas yog 10 ω. Qhov ua rau muaj kev tsis zoo yog qhov kev siv tsis yog ntawm r × 1 iav kom ntsuas lub zog loj, ua rau muaj hluav taws kub ntawm R16. Muaj ob txoj hauv kev los kho lub shunt tiv:
Thawj txoj kev: Siv cov hlau manganese tooj liab kwv yees li 1m ntev thiab 1 {}}}}}}} ... 6}} 1 hli nyob rau hauv lub cheeb thiab qhwv nws ib ncig ntawm cov roj hmabwood thav duab. Thaum tsis muaj roj carbon monoxide, lub zog tiv thaiv lub cev, cov resistor nrog kaum ntawm k ω thiab 1/2w tseem siv tau los hloov chaw. Siv lub siab-precision mulcension, xws li MF18 hom, txhawm rau ntsuas qhov tsis kam ntawm manganese tooj liab hlau. Xaiv ib ntu ntawm 40 ± 0.4 ω thiab qhwv nws ib ncig ntawm cov roj hmab roj hmab hnav lossis cov resistor. Weld ob leeg ua ke thiab hloov lawv. Ntawm chav kawm, nws yog qhov zoo tshaj plaws los siv cov digital motimeter lossis choj kom ntsuas qhov tsis kam ntawm manganese tooj liab xaim, uas yog qhov tseeb dua. Yog tias koj tsis muaj cov hlau manganese tooj liab ntawm tes, koj tuaj yeem hloov nws nrog lub qhov txhab uas muaj zog ntawm cov hlau core los ntawm kev tshem tawm cov hlau kub. Tab sis qhov ntsuas kub ntawm cov xov hluav taws xob cua sov yog cov neeg pluag. Txhawm rau tiv thaiv cov kab luv luv ntawm cov lem thaum lub sij hawm winding, wiring grooves tuaj yeem foob rau ntawm cov roj hmab hnav.
Qhov thib ob txoj kev yog siv ob 20 ω, 1 / 4w hlau zaj yeeb yaj kiab tawm tsam hauv series hloov rau R16. Cov kev tsis kam ua yuam kev yuav tsum tsawg dua 1%.
