Lub thawv tswj tau siv rau kev tswj hwm, ntsuas, tiv thaiv, kis thiab xa tawm ntawm cov khoom txawb lossis lub tshuab hluav taws xob me me. Nws feem ntau yog cov qauv hlau kaw, stamped thiab welded nrog zoo hlau daim hlau.
Lub thawv tswj tau feem ntau yog ntsia rau sab nraum qab ntawm lub tshuab hluav taws xob los ntawm kev siv lub tshuab hluav taws xob thiab yog siv ua ke nrog lub tshuab hluav taws xob. Daim duab 13-4 qhia txog KXDF hom tshuab hluav taws xob teeb tsa tswj lub thawv. Lub vaj huam sib luag yog nruab nrog ammeter, voltmeter, zaus ntsuas hluav taws xob, ntsuas hluav taws xob, hloov hluav taws xob hloov, qhov ntsuas qhov tshwm sim, qhov hloov hluav taws xob tsis siv neeg thiab AC / DC lub qhov (socket), thiab lwm yam, uas tuaj yeem yooj yim saib xyuas lub zog hluav taws xob ua haujlwm ntawm cov xwm txheej thiab ua haujlwm.
Sab ntawm lub npov tswj kav kuj tseem nruab nrog rheostat lub chaw sib nqus kom thiaj li hloov qhov ntsuas hluav taws xob lossis lub zog ntawm lub tshuab hluav taws xob teeb. Tus naj npawb ntawm cov meters rau ntawm cov tswj lub thawv vaj huam sib luag sib txawv nrog lub peev xwm ntawm lub tshuab hluav taws xob teeb thiab cov neeg siv xav tau. Qhov ua kom zoo siab ntawm lub tshuab hluav taws xob teeb tau sib txawv, thiab cov cuab yeej siv los kho lub tshuab hluav taws xob voltage kuj txawv. Ntxiv rau qhov hais los saum toj no rheostat sib nqus teb rheostat, qee cov siv reactors siv, thiab kev tswj qhov tsis zoo no feem siv (AVR) yog siv rau cov kev cai hluav taws xob siab.
