Yog vim li cas vim li cas xoom kab thiab kab nyob txhua qhov ci nrog lub cwj mem hluav taws xob
Nws yuav tsum yog tias cov kab nruab nrab yog nyob rau hauv kev sib cuag tsis zoo nyob rau qhov twg, thiab qhov hloov pauv tsis tswj cov kab theem. Yog tias qhov kev ntsuam xyuas ntawm cov kab nruab nrab yog qhov ci, cov kab nyob txuas nrog los ntawm cov hluav taws xob hluav taws xob.
Cov hlau nruab nrab tau tawg ua ntej qhov chaw koj ntsuas nrog lub cwj mem hluav taws xob, uas yog hais tias, hluav taws xob tawm ntawm cov hlau nyob, qhov hloov koj kaw, los ntawm cov khoom siv hluav taws xob, mus rau qhov chaw koj ntsuas, vim tias cov hlau nyob thiab cov nruab nrab hlau yuav tsum tsim ib lub voj nrog cov khoom siv hluav taws xob. Cia cov khoom siv ua haujlwm. Yog li, koj yuav tsum tau tos kom txog thaum koj pom qhov tawg, sab nraud ntawm qhov tawg yog qhov xoom kab
Kev tshuaj xyuas ntawm cov laj thawj vim li cas ob qho tib si nruab nrab thiab nyob ntawm cov xov hlau raug them:
1. Cov hlau nruab nrab ntawm lub faulty jack muaj kev sib cuag tsis zoo, nws tsis tawg lossis kev sib cuag tsis zoo. Keeb kwm, cov hlau nruab nrab tsis muaj zog, tab sis yog tias lub plugboard muaj lub teeb pom kev zoo ntawm lub teeb, lub zog ntawm cov hlau nyob yuav los ntawm lub teeb qhia no. .
2. Zoo ib yam li saum toj no, tab sis tsis muaj qhov taw qhia lub teeb ntawm lub rooj tsav xwm ntsaws no, thiab nws qhia tau tias lub rooj tsav xwm ntsaws yog dotted. Qhov no feem ntau yog vim hais tias lub rooj tsavxwm ntsaws yog qias neeg, piv txwv li, nws tau tsau rau hauv dej, thiab tom qab nws qhuav, tsis muaj luv luv Circuit Court nyob rau hauv multimeter ntsuas, thiab tus nqi kuj yog infinite. Tab sis txawm tias muaj kev tiv thaiv ntawm kaum ntawm megohms, 220-volt AC Circuit Court yuav muaj ntau lub microamperes ntawm tam sim no, yog li qhov xwm txheej no txaus los teeb pom kev kuaj cov hlau lead, (tshwj xeeb tshaj yog cov ntawv xeem digital, uas muaj kev nkag siab zoo dua) thiab kev txiav txim tsis ncaj yog xoom. Txuas nrog hluav taws xob
3. Cov av noo ntawm ib puag ncig thiab induction ntawm AC. Thaum cov kab ntub dej, txawm hais tias ib puag ncig qhuav heev, kab kuj tseem yuav ntub. Piv txwv li, thaum lub plugboard raug coj los ntawm chav txias mus rau chav sov, yuav muaj ib txheej ntawm cov dej zoo heev ntawm nws, uas koj tsis tuaj yeem pom txhua. Vim tias koj yuav tsis siv lub iav tsom iav kom pom zoo li lub plugboard. Yog tias koj pom luv luv, yuav muaj ib txheej pos huab ntawm koj lub tsom iav sai li sai tau thaum koj nkag mus rau hauv chav, koj yuav pom tam sim ntawd thiab nrhiav ib daim ntaub los so. Nyob rau tib lub sijhawm, koj yuav tsis so lub phaj ntxig uas koj nqa tuaj nrog ib daim ntaub qhuav. Ntxiv dua thiab, txawm tias lub plugboard kuj tseem npog nrog ib txheej ntawm cov dej ntws.
Tsis tas li ntawd, AC tuaj yeem raug ntxias. Lo lus raug yuav tsum hu ua electromagnetic radiation. Txawm hais tias nws tsuas yog 50 Hz, kuj tseem muaj hluav taws xob, tab sis tus nqi hluav taws xob yog tib yam. Qee zaum lub raj neon ntawm lub cwj mem hluav taws xob teeb vim yog hluav taws xob. Lub high-voltage kab ntawm lub qub TV, hluav taws xob cwj mem Lub neon raj pib lub teeb ntawm qhov deb ntawm 200 mm, vim hais tias ntawm high-voltage thiab high-frequency hluav taws xob. Yog li ntawd, nws tsis yog qhov kev xeem cwj mem qhia tau hais tias nws raug them, yog li nws raug nqi tiag tiag.
Piv txwv li: Yog tias koj xav txiav txim siab seb cov kab nruab nrab puas raug them tiag tiag lossis kev txiav txim tsis raug, txuas lub teeb lub teeb rau lub teeb lub qhov (socket), ntsaws ib kawg rau hauv qhov nruab nrab kab qhov uas ntseeg tau tias muaj hluav taws xob, thiab ntsaws rau lwm qhov kawg. ib qho yooj yim nruab nrab kab qhov. Yog hais tias nws yog nyob rau, lub nruab nrab hlau yog tiag tiag powered. Yog tias nws tsis muaj zog heev, nws txhais tau hais tias cov hlau nruab nrab nrog lub qhov no tawg, thiab muaj qhov muag luv luv ntawm cov hlau nyob thiab lub qhov nruab nrab ntawm cov hlau. Cov luv luv luv luv yog feem ntau qias neeg los yog oily. Los yog tau nyob hauv dej. Tej zaum koj yuav hais tias kuv lub plugboard yeej tsis tau dej nyab, tab sis tej zaum koj tus poj niam tau nchuav dej thaum nws dhau ntawm no, lossis nws ib zaug siv lub plugboard los ntsaws rau hauv lub tshuab hluav taws xob ua noj, thiab cov mov tau siav. Nws puv, koj tsuas tsis paub nws.
