Yuav ua li cas yog tias koj sim sim FireWire 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 qhov kev tiv thaiv tus nqi ntawm no siab resistor 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. , kom tsis txhob muaj qhov kev ntsuam xyuas muaj qhov loj dua tam sim no los ntawm lub 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 high voltage. , lub sij hawm no lub raj neon yuav tsis ci (los yog tsis muaj zog brightness), yuav muaj ib tug tsis ncaj ncees lawm kev txiav txim, uas yuav ua rau electrocution ntawm 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 nrog 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 soj ntsuam. 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.
Vim cov duab saum toj no qhia tau hais tias qhov yooj yim stylus kev ntseeg siab tsis yog siab heev, nyob rau hauv kev saib xyuas ntawm AC220V kab, nws yog qhov zoo tshaj plaws los siv cov multimeter AC voltage iav los ntsuas AC high voltage.
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 mus rau 200V AC voltage iav, tus cwj mem dub tiv tauj nrog av lossis phab ntsa, tus cwj mem liab nyob hauv kev sib cuag nrog ob lub xov hlau, yog tias tus cwj mem liab sib cuag nrog xoom kab, lub multimeter qhia tau hais tias qhov hluav taws xob me me, ze li ntawm 0 volts, yog tias tus cwj mem liab tiv nrog kab hluav taws, lub multimeter qhia tau hais tias qhov voltage feem ntau yog kaum ob volts lossis ntau. 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 ntsuas FireWire nrog lub stylus. 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 tsim los ntawm kev sib xyaw ntawm cov khoom siv granular conductive, tsis yog cov khoom siv hmoov rau cov khoom ntim, thiab cov nplaum. 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 nthuav tawm ib tug tawg Circuit Court, uas yog, txawm hais tias lub neon raj tsis puas, tab sis nws tsis teeb, tab sis tus neeg tuav lub stylus los ntsuas cov hluav taws xob hlau yuav tsis raug electrocuted.
Kev phom sij ntawm hluav taws xob tshwm sim thaum, thaum xub thawj, muaj lub zog hluav taws xob hauv hluav taws xob, vim hais tias cov resistor ntawm lub stylus puas lawm thiab qhia yuam kev tias tsis muaj hwj chim, nws yog ib qho yooj yim rau tib neeg kov cov hluav taws xob los ntawm kev ua yuam kev thiab 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 kis.
Ib qho yog disconnected (qhov no yog ntau dua), qhov kev tiv thaiv yog txiav, 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 raug them kom tsis ncaj ncees lawm;
Qhov thib ob, luv luv Circuit Court (qhov no tsawg dua), lub stylus neon raj vim lub siab ceev ceev thiab tawg (neon npuas ib txwm ua haujlwm voltage ntawm 70V), tom qab ntawd, neon raj ua lub luag haujlwm ntawm kev tuav pov hwm, yuav tsis ua mob rau tib neeg. .
