Kodi cholumikizira chingwe ndi chiyani

Chingwe chapakati chapakati ndi chipangizo chomwe chimagwirizanitsa chingwe ndi bokosi lolowera, ndipo chimagwiritsidwa ntchito kugwirizanitsa chingwe chachitsulo kapena sheath, kutsekemera ndi sheath kwa wina ndi mzake.M'mapulogalamu amagetsi, chiwerengero cha maulumikizidwe apakati ndi okwera.Zolumikizana zapakatikati zodziwika bwino zimakhala ndi mtundu wowongoka (womwe umadziwika kuti "wowongoka") ndi mtundu wa bend.

Makhalidwe amtundu wowongoka ndi awa:
(1) Kapangidwe kosavuta, kakulidwe kakang'ono ndi kulemera kopepuka;

(2) Kumangako ndikosavuta, ndipo kumatha kuyendetsedwa popanda kuvula chingwe chakunja cha chingwe pakuyika;

(3) Mtengo ndi wotchipa, koma kutayika kwa mzere pambuyo pa kuyika ndi kwakukulu.

Makhalidwe a mtundu wopindika ndi awa:
(1) Mapangidwewo ndi ovuta kwambiri;

(2) Kutayika kwa mzere wopangidwa pambuyo pa kuyika ndi kochepa kusiyana ndi mtundu wowongoka;

(3) Kumangako kumakhala kovuta kwambiri;

(4) Mtengo ndi wokwera pang'ono.

Muukadaulo wothandiza, njira yokanira ya DC nthawi zambiri imagwiritsidwa ntchito kuzindikira momwe ntchito ikuyendera.Mfundo ya njira ya DC kukana ndi yakuti magetsi a DC akagwiritsidwa ntchito pa ma electrode awiri a kupyolera, mtengo wotsutsa umakhala wofanana ndi lalikulu la magetsi ogwiritsidwa ntchito.

Chifukwa chake, malinga ngati kukula kwa kukana kwa DC kumayesedwa, ma conductivity odutsa amatha kudziwika.Njira zoyezera kukana kwa DC zimagawidwa m'magulu awiri: njira yachindunji ndi njira yosalunjika:
Njira yolunjika ndikuyesa mwachindunji kutsika kwamagetsi a DC pakati pa ma electrode awiri okhala ndi multimeter kuti mudziwe zabwino ndi zoyipa za kuwongoka.

Njira yosalunjika ndiyo kuweruza ngati ili yoyenerera kapena ayi poyesa njira yosinthira pakati pa ma elekitirodi awiri, yomwe imatchedwa njira ya AC impedance kapena ma frequency amphamvu kupirira njira yoyesera magetsi.Njira yoyeserera yamagetsi yamagetsi ndi imodzi mwa njira zodziwika bwino komanso zothandiza kuweruza ngati gawo lina la conductor ndiloyenera kapena ayi..

Pamene mphamvu yamagetsi yamagetsi yamtengo wotchulidwa (nthawi zambiri 50hz) ikugwiritsidwa ntchito kumapeto kwa kondakitala yoyesedwa, onani ngati chinthu choyesedwacho chili ndi vuto losweka.Sizikugwira ntchito pagawoli lawaya.
