Yuav ua li cas yog hais tias ob qho tib si nyob hlau thiab hluav taws xob xeem cwj mem puas?
Neon raj, springs, thiab high-resistance resistors feem ntau pom nyob rau hauv cov cwj mem xeem. Qhov no high-resistance resistor, uas txuas nrog lub neon raj hauv series, feem ntau muaj qhov tsis kam ntawm M qib. Lub raj neon thiab tib neeg lub cev yog ob qho tib si cuam tshuam los ntawm qhov tam sim no. Qhov tshwm sim ntawm cov resistor puas yog qhov tsawg kawg nkaus, tab sis yog tias muaj qhov txhaum, xws li kev sib cuag tsis txaus ntawm lub resistor, neon raj, thiab lub caij nplooj ntoos hlav, thiab yog tias qhov txhaum tsis paub, siv lub cwj mem hluav taws xob los xyuas qhov ntau dhau ntawm AC voltage. lub cev hluav taws xob.Lub raj neon yuav tsis teeb ntawm qhov taw tes no (los yog nws yuav tsis tshua muaj teeb meem), thiab tus neeg siv yuav ua yuam kev uas yuav ua rau muaj hluav taws xob poob. Tsis tas li ntawd, siv tus cwj mem ntsuas los ntsuas AC220V qhov hluav taws xob yog qhov cuam tshuam rau hluav taws xob poob siab yog tias dej tsis txhob txwm nkag mus rau sab hauv thiab sab hauv yog qhov ntub. Yog li ntawd, koj yuav tsum kuaj xyuas tus cwj mem kuaj mob ua ntej siv nws. Tsis muaj teeb meem, siv nws ib zaug ntxiv.Yuav ntsuas AC siab voltage thaum kho AC220V kab, nws yog qhov zoo dua los siv cov digital multimeter's AC voltage ntau vim qhov yooj yim ntsuas cwj mem qhov kev cia siab qis dua.
Txhawm rau txiav txim siab cov xaim nruab nrab thiab cov xaim nyob thaum siv digital multimeter nyob rau hauv qhov chaw ntawm kev sim cov hlau lead, teeb tsa qhov hloov pauv mus rau AC 200V qhov hluav taws xob ntau, kov cov xim dub coj mus rau phab ntsa lossis hauv av, thiab qhov ntsuas liab ua rau qhov tsim nyog ob kab. Thaum cov hlau kuaj liab ua rau kev sib cuag nrog xoom kab, lub multimeter qhia tau hais tias muaj qhov tsis tshua muaj hluav taws xob uas nyob ze ze rau xoom volts; Txawm li cas los xij, thaum qhov kev ntsuam xyuas liab ua rau kev sib cuag nrog cov hlau nyob, tus nqi feem ntau yog ntau tshaj kaum tawm volts. Siv txoj kev no txhawm rau txheeb xyuas AC high voltage muaj kev nyab xeeb dua li siv tus cwj mem hluav taws xob vim tias tam sim no yuav dhau los ntawm tib neeg lub cev.
① txaus ntshai heev!
Txawm li cas los xij, qhov kev pheej hmoo tsis muaj nyob thaum siv tus cwj mem ntsuas los ntsuas cov hlau nyob. Solid-core resistors, qee zaum hu ua ntim resistors, yog cov resistors siab siv rau hauv cov cwj mem. Cov resistors tuaj nyob rau hauv ob ntau yam: organic hluavtaws solid-core resistors thiab inorganic hluavtaws solid-core resistors. Hom kev tiv thaiv no yog tsim los ntawm kev sib txuas thiab nias cov khoom siv ua cov ntaub ntawv, cov khoom ntim uas muaj cov hmoov tsis zoo, thiab cov binders.Carbon dub thiab graphite yog cov khoom siv granular, thaum mica hmoov, quartz hmoov, iav hmoov, titanium dioxide (titanium dioxide hmoov. ), thiab lwm yam, yog cov khoom siv hmoov tsis zoo. Qee cov nplaum siv cov nplaum nplaum, thaum lwm tus siv cov nplaum nplaum. Raws li hom kua nplaum, ob hom organic khoom core resistors thiab inorganic solid core resistors teev saum toj no tuaj yeem sib cais. Hom resistor no muaj kev ntseeg siab heev, muaj kev tiv thaiv zoo rau overload, thiab nyuaj rau kev puas tsuaj. Thaum puas lawm, nws tseem yuav tso saib lub xeev qhib hluav taws xob, uas txhais tau hais tias txawm tias lub raj neon tsis puas, nws yuav tsis teeb, tab sis tus neeg siv lub cwj mem hluav taws xob los ntsuas cov hlau nyob yuav tsis muaj hluav taws xob poob.
3Thaum cov hlau nyob muaj zog tab sis tus cwj mem ntsuas tus tiv thaiv raug rhuav tshem thiab ua yuam kev qhia tias tsis muaj zog, yuav muaj kev pheej hmoo ntawm hluav taws xob poob. Tib neeg tuaj yeem kov cov hlau nyob thiab tau txais hluav taws xob poob siab.
Muaj ob qhov tshwm sim tau yog tias tus cwj mem hluav taws xob tsis kam tawg (feem ntau yog qhov nyuaj-nias tsis kam nrog tus nqi tsis kam ntawm ntau M):
Ib qho yog kev tsis sib txuas (qhov no nquag tshwm sim), thaum lub tshuab hluav taws xob raug txiav tawm tom qab qhov kev tiv thaiv raug txiav tawm thiab qhov ntsuas tus cwj mem lub neon teeb pom kev tsis muaj tam sim no thiab tsis muaj teeb pom kev zoo, ua rau nws yooj yim rau kev ntseeg yuam kev tias Circuit Court raug kuaj tau hluav taws xob;
Qhov thib ob scenario yog luv luv, uas tsis tshua muaj. Vim tias qhov hluav taws xob siab rau lub sijhawm luv luv (lub teeb neon lub teeb ua haujlwm ib txwm yog 70V), qhov ntsuas tus cwj mem lub neon tube ua haujlwm tsis zoo. Lub raj neon tam sim no ua haujlwm raws li kev tuav pov hwm thiab tsis muaj kev phom sij rau tib neeg.
