Indlela ukuba uhlole i capacitor

Capacitors zisetyenziswa kakhulu yaye ubhetyebhetye iteknoloji, ingakumbi elektroniki. engineering unomathotholo nomabonwakude izixhobo, radar, zeefoni kunye telegraphy, isilawuli esizisebenzelayo kunye remote control, izixhobo computing kunye nezixhobo zombane, laser iteknoloji - oku uluhlu alupheli yeendawo kwesicelo. Zisetyenziswa phantse onke amacandelo ezoqoqosho.

Kucacile ukuba ebanzi isicelo capacitors izizathu kunye neyantlukwano kweentlobo. Kunye capacitors ezincinane, kukho zinde ngokwenene anobunzima aliqela. umthamo wabo lisukela iqhezu PF kumakhulu amawaka microfarads, kwaye amandla ombane sokusebenza kuba asukela volts ezimbalwa ukuya amakhulu ezininzi kilovolts.

Ekuhambeni kwexesha bethu, kuyo yonke indlu kukho zonke iintlobo zasendlini, kwaye, ngenxa yoko, kunye capacitors. Ngelishwa, kaninzi baye lungangaphumeleli ngenxa yezizathu ezahlukeneyo, ngoko umbuzo lo mbuzo, ukuvavanya indlela capacitor kunye multimeter, ngumhloli okanye ohmmeter.

Ukuziqhelisa, amaxesha amaninzi kufuneka ahlole ku isampula kunye ukulahleka kwenxalenye umthamo. Isizathu sokuba ikhefu lu dityanisiwe ezithile ebalulekileyo obuvumelekileyo ombane yokusebenza. Ngokuqhelekileyo, imiqondiso yangaphandle yokuwa kunokubonwa kwi element izindlu - amabala, ukudumba, iintanda, etc ...

Indlela ukukhangela le capacitor multimeter

isixhobo sesandla jikelele uvavanyo zombane - multimeter. Phambi kokuba khangela capacitor, kufuneka sisothula. Kubaluleke ngokukodwa ukuba agcine, ukuqala bokuqinisekisa capacitor polar, ebonakala umthamo omkhulu, ombane aphezulu yokusebenza. Ukungaphumeleli ukwenjenjalo kuya umonakalo imitha. Ukuze ifeze ephantsi ombane capacitor kwanele elifutshane wesekethe kwizigqibo zayo, yaye ukuba ikhulule capacitor eliphezulu-ombane kukwenza ngenxa resistor ukuya ohms-10, ukunqanda iintlantsi. Ngelo xesha izandla zakhe bachukumise izigqibo ayinakuba, okanye kukothuka ezimbi enikiweyo.

Kubalulekile ukwazi ukujonga indlela capacitor kuyo nayiphi na imeko, ngoba iindlela zovavanyo zixhomekeke kwizinto ezininzi.

Indlela elula kodwa ukuqinisekisa ukuba multimeter kokuba umsebenzi womlinganiselo capacitance,, ngelo xesha ke kufuneka ungalibali imfuneko bahloniphe imithetho wokwephuka xa usebenzisa capacitors ezibandayo.

Khangela capacitors multimeter abangenawo umsebenzi okhethekileyo, oko kunokwenzeka yokulinganisa ukuxhathisa mode. Xa wayicima imitha kule imo, kufuneka ukubamba kuphando ukuya umkhondo capacitor ulinde imizuzwana embalwa ukujonga ukufundwa. Ukuba isixhobo wabonakala ixabiso ukumelana ngamabona enkulu - capacitor ngu Kulungile, ukuba kwiqanda - aphume oda. Ukuba inani kwidispleyi kubonisa ukubaluleka kwenye, lo capacitor kukho ukuvuza kwaye ingazehlela ethile.

Ngenxa yoko, umthamo yemitha ngaphandle umsebenzi yokuqinisekisa ikuvumela ukuba ukhankanye kuphela iimpawu ubunjani le capacitor, kodwa, ubuncinane, yenza kube lula ukwenza izigqibo malunga imfuneko yokukhupha kuyo.

Nangona kunjalo, olu vavanyo kushiya ayiphendulwanga umbuzo olandelayo - ukujonga njani yesekethe capacitor. Ukonakala yale hlobo kunokwenzeka ukuba ngokungaphelelanga okanye ngokupheleleyo lungqubano ingqibelelo Heating ngaphakathi kwi seli. Loo capacitor lubonisa ukunganyangeki ongapheliyo, kodwa bathembele eli nani njengobungqina okulungileyo yayo akunakwenzeka.

Ukwazi ukuba ukujonga njani capacitor tester, unako kwakhona ukuqinisekisa ukuba imida yayo umthamo elikhankanyiweyo nokumelana. Ulwazi amandla ngokwenene kuyimfuneko ukuba wenze isigqibo malunga ozothatha indawo yakhe okanye ukusetyenziswa ngakumbi.
