Yuav ua li cas yog tias koj sim sim FireWire cable nrog lub stylus tawg?
Lub stylus feem ntau yog tsim los ntawm ib tug siab resistor, neon raj thiab lub caij nplooj ntoos hlav thiab lwm qhov chaw ntawm no high resistance resistor tus nqi yog feem ntau nyob rau hauv lub MΩ theem, nws kev sib raug zoo nrog lub neon raj nyob rau hauv series, lub luag hauj lwm yog txwv tsis pub tam sim no, zam kev sim cov dej ntws loj dua los ntawm cov raj neon thiab tib neeg lub cev. Qhov muaj peev xwm ntawm kev puas tsuaj rau cov resistor yog me me, tab sis cov resistor thiab neon raj thiab lub caij nplooj ntoos hlav yog tias muaj kev sib cuag tsis zoo ntawm qhov kev ua tsis tiav, thaum tsis muaj kev paub txog qhov txhaum, tus cwj mem los ntsuas lub cev them nrog AC siab. -voltage, lub sij hawm no lub neon raj yuav tsis ci (los yog brightness yog heev qaug zog), yuav muaj ib tug misjudgement, yog li electrocuting tus neeg siv. Tsis tas li ntawd, yog hais tias lub stylus inadvertently mus rau hauv cov dej nyob rau hauv, nyob rau hauv lub ntub dej ntau, lub sij hawm no tus cwj mem los ntsuas qhov voltage AC220V, nws kuj yog ib qho yooj yim heev rau electrocution, yog li nyob rau hauv kev siv cov stylus ua ntej lub stylus yuav tsum tau kuaj ua ntej. lub stylus yog qhov zoo los yog phem, kom paub meej tias tsis muaj qhov yuam kev thiab tom qab ntawd mus siv.
Nrog lub tshuab hluav taws xob digital es tsis txhob siv lub stylus los txiav txim qhov xoom kab thiab kab hluav taws, koj tuaj yeem hloov nws qhov ntau rau AC 200V voltage iav, tus cwj mem dub kov hauv av lossis phab ntsa, tus cwj mem liab tau nyob rau hauv kev sib cuag. nrog rau ob lub xov hlau, yog tias tus cwj mem liab yog nyob rau hauv kev sib cuag nrog xoom kab, lub multimeter qhia ib tug me me voltage, ze rau 0 volts, yog hais tias tus cwj mem liab yog nyob rau hauv kev sib cuag nrog cov hluav taws kab, lub multimeter qhia qhov voltage yog feem ntau ntau. tshaj kaum tawm volts. Nws muaj kev nyab xeeb dua los ntsuas AC high voltage nyob rau hauv txoj kev no, tsis zoo li lub stylus, uas yuav muaj tam sim no ntws los ntawm lub cev.
① Nws yog qhov txaus ntshai!
② Txawm li cas los xij, qhov phom sij tsis tshwm sim thaum koj siv lub stylus los ntsuas FireWire. Lub siab resistors siv nyob rau hauv lub stylus yog cov khoom-core resistors, kuj hu ua ntim resistors, uas tau muab faib ua ob pawg: organic synthetic solid-core resistors thiab inorganic synthetic solid-core resistors. Cov resistors no yog nias los ntawm kev sib xyaw ntawm cov khoom siv granular conductive, cov khoom siv hmoov tsis siv los ua cov khoom ntim, thiab cov ntawv khi. Granular conductive khoom yog carbon dub thiab graphite; Cov khoom siv uas tsis yog-conductive yog mica hmoov, quartz hmoov, iav hmoov, titanium dioxide (titanium dioxide hmoov), thiab lwm yam.; binder yog siv nyob rau hauv tej rooj plaub uas siv cov organic binder, ib co siv inorganic binder, lub aforementioned organic solid-core resistors thiab inorganic solid-core resistors ob pawg yog raws li hom binder kom paub qhov txawv. Hom resistor no muaj zog tiv thaiv overload, muaj kev ntseeg siab, thiab tsis yooj yim puas. Nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj, nws kuj tau nthuav tawm raws li lub xeev disconnected, uas yog, lub neon raj tsis puas tab sis tsis kaj, tab sis tus neeg tuav lub stylus los ntsuas cov hluav taws xob yuav tsis raug electrocuted.
Kev phom sij ntawm hluav taws xob tshwm sim thaum muaj hluav taws xob hauv hluav taws xob, thiab thaum lub resistor ntawm lub stylus puas thiab yuam kev qhia tias tsis muaj hwj chim, nws yog ib qho yooj yim rau ib tug neeg kov cov hluav taws xob los ntawm kev yuam kev thiab raug hluav taws xob!
Lub stylus resistor (feem ntau yog cov khoom compression resistor, tus nqi kuj nyob rau hauv ob peb M) yog phem, yuav muab faib ua ob rooj plaub: ib tug yog disconnected (qhov no yog feem ntau cov ntaub ntawv), lwm yam yog disconnected.
Ib qho yog disconnected (qhov no yog ntau dua), tom qab qhov kev tiv thaiv yog disconnected, lub hwj chim Circuit Court yog disconnected, lub stylus neon npuas tsis muaj tam sim no, neon npuas tsis teeb, yooj yim rau kev ntsuas ntawm lub Circuit Court them qhov teeb meem tshwm sim los ntawm misjudgment;
Qhov thib ob yog luv luv Circuit Court (cov ntaub ntawv no tsawg dua), lub stylus neon raj vim lub siab ceev ceev thiab tawg (neon npuas ib txwm ua hauj lwm voltage ntawm 70V), ces, lub neon raj ua si lub luag hauj lwm ntawm kev tuav pov hwm, yuav tsis ua. ua mob rau tib neeg.
