Yuav ua li cas yog hais tias ob qho tib si nyob hlau thiab hluav taws xob xeem cwj mem puas?
Sab hauv ntawm tus cwj mem xeem feem ntau yog tsim los ntawm cov khoom siv hluav taws xob siab, cov raj neon thiab cov springs. Qhov kev tiv thaiv ntawm qhov kev tiv thaiv siab tiv thaiv no feem ntau yog nyob ntawm MΩ theem, thiab nws txuas nrog hauv koob nrog neon raj. Tam sim no ntws 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 yog tias muaj qhov txhaum xws li kev sib cuag tsis zoo ntawm cov resistor, lub neon raj thiab lub caij nplooj ntoos hlav, yog tias qhov txhaum tsis paub, siv lub cwj mem hluav taws xob los ntsuas seb lub cev hluav taws xob puas muaj AC. high voltage. Thaum lub raj neon yuav tsis teeb (lossis qhov ci ntsa iab tsis muaj zog), kev txiav txim siab yuav tshwm sim, uas yuav ua rau tus neeg siv tau txais hluav taws xob poob siab. Tsis tas li ntawd, yog tias dej tau nkag mus rau sab hauv ntawm tus cwj mem xeem, thiab sab hauv yog qhov ntub dej, lub sijhawm no, siv tus cwj mem ntsuas los ntsuas AC220V voltage kuj ua rau hluav taws xob poob siab, yog li ua ntej siv tus cwj mem xeem, koj yuav tsum xyuas seb tus cwj mem xeem puas zoo los tsis siv dua yam tsis muaj teeb meem.
Thaum siv lub tshuab hluav taws xob digital es tsis txhob siv qhov kev xeem coj los txiav txim rau cov xaim nruab nrab thiab cov xaim nyob, koj tuaj yeem kho nws qhov hloov pauv mus rau AC 200V voltage ntau, kov qhov ntsuas dub ua rau hauv av lossis phab ntsa, thiab qhov kev kuaj liab ua rau kov ob lub xov hlau sib. Yog hais tias qhov kev ntsuam xyuas liab kov kov xoom Kab, qhov hluav taws xob tso tawm los ntawm multimeter me me, ze rau 0 volts, yog tias tus cwj mem liab kuaj yog nyob rau hauv kev sib cuag nrog cov nyob hlau, qhov voltage tso tawm los ntawm multimeter feem ntau yog siab tshaj kaum tawm volts. Siv cov qauv no los ntsuas AC high voltage tsis zoo li tus cwj mem hluav taws xob, yuav muaj qhov tam sim no ntws los ntawm tib neeg lub cev, uas muaj kev nyab xeeb dua.
① txaus ntshai heev!
②Txawm li cas los xij, qhov phom sij tsis tshwm sim thaum ntsuas cov hlau nyob nrog tus cwj mem xeem. Cov resistors siab-resistors siv nyob rau hauv lub xeem cwj mem yog solid-core resistors, tseem hu ua ntim resistors, uas tau muab faib ua ob pawg: organic synthetic solid-core resistors thiab inorganic synthetic solid-core resistors. Hom kev tiv thaiv no yog tsim los ntawm kev sib xyaw thiab nias cov khoom siv hluav taws xob, cov khoom siv hmoov tsis yog siv los ua cov khoom ntim, thiab cov ntawv khi. Granular conductive cov ntaub ntawv yog carbon dub thiab graphite; Cov ntaub ntawv uas tsis yog-conductive yog mica hmoov, quartz hmoov, iav hmoov, titanium dioxide (titanium dioxide hmoov), thiab lwm yam.; Qee cov nplaum siv cov nplaum nplaum, thiab qee qhov siv cov nplaum nplaum Cov ob hom organic khoom core resistors thiab inorganic solid core resistors tau hais los saum no yog qhov txawv raws li hom nplaum. Hom resistor no muaj zog tiv thaiv overload, muaj kev ntseeg siab, thiab tsis yooj yim rau kev puas tsuaj. Nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj, nws tseem yuav qhia ib tug qhib lub xeev Circuit Court, uas yog, lub neon raj yuav tsis teeb txawm tias nws tsis puas, tab sis tus neeg tuav lub hwj chim cwj mem los ntsuas cov nyob hlau yuav tsis tau ib tug hluav taws xob shock.
③ Qhov phom sij ntawm hluav taws xob poob siab tshwm sim thaum lub xov hlau nyob yog siv, tab sis lub resistor ntawm tus cwj mem xeem raug puas tsuaj thiab qhia tsis tseeb tias tsis muaj hwj chim. Tib neeg yuav kov cov hlau nyob ntawm qhov yuam kev thiab tau txais hluav taws xob poob siab!
Yog tias qhov kev tiv thaiv ntawm tus cwj mem hluav taws xob tawg (feem ntau yog cov khoom pressed tsis kam, tus nqi kuj yog ob peb M), nws tuaj yeem muab faib ua ob qhov xwm txheej:
Ib qho yog kom tshem tawm (qhov no feem ntau yog qhov teeb meem), tom qab qhov kev tiv thaiv raug txiav tawm, lub tshuab hluav taws xob raug txiav, lub neon teeb ntawm lub ntsuas cwj mem tsis muaj tam sim no, thiab lub teeb neon tsis teeb, uas yooj yim rau kev txiav txim siab tsis zoo. ntawm lub electrification ntawm Circuit Court nyob rau hauv kev sim;
Qhov thib ob yog luv luv Circuit Court (qhov xwm txheej no tsis tshua muaj). Lub raj neon ntawm lub ntsuas mem tawg vim qhov hluav taws xob siab rau ib pliag (qhov ua haujlwm ib txwm ua haujlwm ntawm lub teeb neon yog 70V). Lub sijhawm no, lub raj neon ua lub luag haujlwm pov hwm thiab yuav tsis ua mob rau tib neeg.
