Mmene mungayese makina osakanikirana

Chimodzi mwa magawo ofunikira kwambiri omwe amachititsa mbali iliyonse ya dera lamagetsi ndi kukana kwa magetsi. Malingaliro ake enieni ndi omwe ali otsogolera kutsutsa njira ya magetsi. Zimadalira zochitika za atomiki za zinthu zakuthupi ndi zakunja. Kuwerengera kwa magetsi kwa mbali iliyonse ya dera kumatha kudziŵika mosavuta podziwa magetsi pamapeto a kusiyana kwake ndi pakali pano. Kuti mudziwe kukanika, ndikokwanira kugawaniza mphamvu yamagetsi ndi yamakono. Ichi ndi mawonekedwe otchuka a Ohm (ntchito yake yonse).

Kuphatikiza pa kuwerengetsera molunjika, mu ntchito yogwira ntchito ndi magetsi, njira yeniyeni ya kukana imagwiritsidwa ntchito nthawi zambiri. Zida zofunikira zimagwiritsidwa ntchito pa izi. Mmodzi mwa otchuka kwambiri, kulola ngakhale munthu wosadziwika ali ndi zamagetsi kupanga magetsi, akuyimiridwa ndi multimeter (digito kapena analogog). Cholembera cha chipangizocho chimapanga mphamvu yeniyeni komanso yamakono, podziwa kuti, ndi zophweka kudziwa momwe mungatsutsire ndikuwonetsa mtengo wake mwa mawonekedwe pawonetsero kapena kupotoza kwa chithunzi.

Kuyeza kwa kukana sizongopeka, koma zothandiza. Ntchito yokhudzana ndi kukonza maulendo a magetsi amafunikira kugwiritsa ntchito nthawi zambiri zipangizo zoyesera. Kupanga nthawi yeniyeni ya kukana kwa zinthu zawo, mukhoza kutsimikiza kuti ntchito yonse ikupitirizabe.

Munthu aliyense amene amadziwidwa ndi magetsi amadziwika bwino ndi njira zomwe makina osakanikirana nawo amayeza . Zina mwa izo, zosavuta komanso zofikira kwambiri ndizogwiritsira ntchito chipangizo chapadera - o ohmmeter. Ndikoyenera kulitcha "megger" (megaohmmeter), popeza kutetezedwa kwachingwe kwa chingwe, pambuyo pake, kumayesedwa mu zikwi zambiri za ma ohm.

Mayeso oteteza kusakanikirana ayenera kuchitidwa pamaganizo alionse okhudzidwa ndi kusintha kwake. Ngati pali kuwonongeka kwanuko (makina, kutentha, mankhwala), ndiye kuti kuyang'anitsitsa mwachindunji sikukwanira. Kufufuza kusungunula n'kofunikira ngati madzi akulowa pakati pa zowonongeka kwa chingwe, komanso kuti asagwiritse ntchito nthawi yaitali. Ma meghmeter amafunika kuti ayesedwe, malire ake omwe amalola kuyerekezera kusakanikirana, ndi kumapeto kwa chingwe. Kukhazikika kwachilendo koyipa kumadalira mphamvu yomwe chipangizocho chimagwirira ntchito. Mwachitsanzo, ngati chingwecho chikugwiritsidwa ntchito kupititsa zikwi za volts, ndiye kuti zikhoza kuonedwa ngati zachilendo (ngati zili zovomerezeka), ngati mliriwu ndi 1 miliyoni imodzi pa 1 kilovolt. Kusintha kwapansi kumasintha makalata: 1 kilo kuti 1 volt.

Ambiri a meggerometers amagwiritsa ntchito dynamo ngati gwero la magetsi, kotero muyenera kuzungulira mphutsi paulendo woyenera kuti muyese. Kusungunula kwa chingwe chotsekemera kumayambika kuchokera kufalikira kwa magetsi kumbali zonse ziwiri za gawolo, ngati n'kotheka (ngati kugwirizana kwawo kumbali imodzi, kukanika kumayang'aniridwa, komwe kuli kovomerezeka, ngakhale kosavomerezeka). Pulojekiti imodzi ya megger imagwiritsiridwa ntchito mosavuta kwa woyendetsa aliyense pamutu, ndipo yachiwiri pansi (misa).

Pamene chogwedeza cha chipangizochi chikusinthika, kusakanikirana kwazomwekukuwonetseratu kumawonetsedwa poyambirira ndi maziko. Ngati ziri mkati mwa malire ololedwa, zotsatirazi zikutsatiridwa: kutsutsana pakati pa mapiritsi kumayang'aniridwa. Kuti tichite izi, kafukufuku wina amakhudza mitsempha yotsutsana, ndipo yachiwiri - mwachindunji kwa zotsatirazi. Kusinthasintha mphuno, fufuzani mtengo wokaniza. Poyesedwa ndi megger, mpweya waukulu umagwiritsidwa ntchito ku chingwe , kotero simungakhoze kuchigwira. Pambuyo poyesa miyeso, chigawo chilichonse chiyenera kumasulidwa mwa kuchigwira icho ku chinthu chachitsulo chokhazikika.
