Kutchinjiriza kukana: kufunika miyezo

Ngati muli bwino nkhani magetsi (ngakhale pang'ono), ziyenera kudziwika ndi mbali monga magetsi Kulumikizana kutchinjiriza kulimbikira mawaya zitsulo. kutchinjiriza khalidwe Mzimuyo kudalirika kwa Kulumikizana, dongosolo la zipangitsa Mwachangu wa akubera kwa zinthu zimene akufuna. Zikugwira ntchito malamulo amasonyeza kuvomerezedwa nthawi review mlingo ofunikira kutchinjiriza ntchito Kulumikizana ndondomeko yomwe imakhala mu kuyeza kukana pogwiritsa pansi.

Mfundo macheke zonse kutchinjiriza ntchito kunyumba ndi ntchito m'malamulo wapadera zipangizo zamagetsi alipo. Pakati pawo, GOST, PUE (malamulo a zipangizo zamagetsi) ndi ena. Mulimonsemo, mayeso a kutchinjiriza kukana ziyenera ziziyezedwa Megger. chipangizo ali mu kapangidwe kake ndi voteji gwero, gwero la resistances zina ndi magneto-magetsi chiŵerengero-mita. Monga jenereta voteji kutenga mphamvu, koma chimake abwino ndi galimoto Buku.

Popeza megaommetry ntchito pamaso pa gwero la padziko mwachindunji, n'zotheka kudziwa kutchinjiriza kukana pa voteji okwera. Tisaiwale kuti mu nkhani ya kulumikiza megger kuti unit mayeso, omwe amasonyeza kukana kwambiri saganizira, ndiye amachepetsa monga chipangizo linanena bungwe voteji chingwe.

Kuyeza kutchinjiriza kukana ayenera kukhala mu masiteji:

1. mu dera mayeso, voteji-free.
2. Ngati mtengo dera kukana Sizikudziwika m'pofunika kukhazikitsa pakhomo la muyeso kwa phindu pazipita.
3. Short-circuited kapena kwathunthu kuletsa onse zinthu yogwira dera ndi pamlingo wochepa wa kutchinjiriza, kuphatikizapo capacitors, zipangizo ndi semiconductors.
4. Kuuluka dera poyesedwa pa ntchito choyezera.
5. Kupereka mphamvu kwa megohmmeter mkati mphindi. Kuyeza pamlingo chipangizo.
6. Atamaliza miyezo, ndi malekezero a chipangizo kusagwirizana ku dera la, kuchotsa anasonkhanitsa mlandu pa njira dera grounding.

Muyeso wa kutchinjiriza kulimbikira madera Kulumikizana ndi phindu lalikulu capacitance bwino anachita pambuyo kutha lathunthu la oscillation wa chida Cholozera. Gawo mu kuunikira ndi mphamvu Intaneti kuthamanga mu mode likhale lawo, anaika pa lama fuyusi-kugwirizana ndi sakukhudzidwa ndi mmene zopezera amalandira magetsi.

Malamulo zoletsedwa kugwira miyezo pa mizere anaika pafupi mzere, amene ali pansi pa voteji mkulu, komanso akuletsedwa ntchito pa chiphaliwali. Makamaka mu kutchinjiriza kukana amakhudza boma kutentha. Kuti idzitha kuyezeka pa kutentha madigiri 5 kapena pamwamba.

Pali makhazikitsidwe DC, pamene chipangizo kulamulira amachita ngati voltmeter kuyeza kutchinjiriza kukana, ndi digiri yapamwamba ya kukana mkati. Pankhaniyi, kuyang'ana pa ntchito a mitundu itatu nkhawa: pakati pa mizati pakati pa dziko lapansi ndi chilichonse mtengo.

zamagetsi ZIMAKHALA ndi zitsanzo za pakompyuta mamita megohm: F4101, F4102; iwo ndinazolowera ntchito pa voteji 100, 500 ndi 1000 V. Komanso mu njira ya mitundu wamkulu mamita megohm ku M4100 / 1 ndi M4100 / 5, ndi MS-05.
