Chitetezo cha kutayikira kuti chikhale chotetezeka.

Kodi ndi chiyanichosokoneza dera lotayikira?

Chotsekera dera chotayikira, imagwiritsidwa ntchito poletsa kugwedezeka kwa magetsi. Pakagwa kutayikira, mphamvu ya maginito imapangidwa ndi cholumikizira chachikulu, cholumikizira cholumikizira chogawa, cholumikizira cholumikizira chogawa ndi switch yayikulu.

Chotsekera dera chotayikirantchito: pamene dera lafupikitsa kapena kuchulukira kwa magetsi kungakhale koyenera, dulani magetsi.

Ngati pali choteteza kutayikira mu dera, ngati kutayikira kapena kutayikira kwachitika, choteteza kutayikira sichigwira ntchito ndipo chidzatumiza chizindikiro cha alamu yamawu ndi kuwala. Sikofunikira kuletsa ndi manja.

Zolinga zazikulu:

1. Kuteteza chitetezo cha munthu payekha ngati zipangizo zamagetsi zapakhomo kapena zamagulu onse zitatayikira.

2. Iyenera kuyikidwa m'malo opezeka anthu ambiri komanso m'malo oyaka moto komanso ophulika (monga malo opangira zinthu, malo osungiramo katundu, ndi zina zotero) komwe anthu nthawi zambiri amasamukira kuti apewe moto ndi ngozi zina zomwe zimachitika chifukwa cha kutayikira kwa magetsi.

Sizingagawidwe gwero lamagetsi ndi zida zina zamagetsi.

1. Chotchingira choteteza kutayikira kwa madzi chimatha kutseka magetsi mwachangu ngati magetsi agwera pagawo limodzi kapena vuto la nthaka pa netiweki yamagetsi otsika mphamvu, motero kuonetsetsa kuti zida za munthu payekha siziwonongeka.

2. Ngati chosinthira choteteza kutuluka kwa madzi ndi zida zamagetsi zalephera nthawi imodzi, vuto la kutuluka kwa madzi pa zida zamagetsi likhoza kuchotsedwa mwachisawawa kuti lisatayike mphamvu zonse zamagetsi, motero kuonetsetsa kuti munthu ali otetezeka komanso kupewa kufalikira kwa ngozi zamagetsi.

3. Mu gridi yamagetsi yotsika ya mawaya anayi ya magawo atatu, pamene vuto la nthaka ya gawo limodzi lachitika, magetsi amatha kuzimitsidwa mwachangu komanso panthawi yake kuti apewe kukula kwa ngoziyo.

4. Kusankha kwa switch yoteteza kutayikira ndi kwabwino kwambiri chifukwa cha ntchito zake ziwiri: kutulutsidwa kwa overcurrent (TN -C) ndi kutulutsidwa kwa overload (TT-B).

5. Pamene mfundo ziwiri za mota zakhazikika chifukwa cha kugwedezeka kwa magetsi kapena pazifukwa zina, magetsi amatha kuzimitsidwa mwachangu komanso modalirika.

Musagwiritse ntchito magetsi a gawo limodzi powunikira.

Kukhazikitsa chitetezo cha kutayikira: 1. Kukhazikitsa chitetezo cha kutayikira kuyenera kutsatira malamulo oyenera, malo ake ayenera kukhala olimba komanso odalirika, ndipo ayenera kutsekedwa ngati pakufunika kutero.

2. Chiwerengero cha choteteza kutayikira chiyenera kutsimikiziridwa ndi wogwiritsa ntchito malinga ndi momwe amagwiritsidwira ntchito, koma nthawi zambiri sichiyenera kupitirira mphamvu yogwira ntchito yotetezeka (30mA).

3. Chitsanzo ndi tsatanetsatane wa choteteza kutayikira ziyenera kukhala zoyenera pa chingwe cholumikizira.

4. Ma terminal a choteteza kutayikira ndi malekezero onse awiri a chingwe chonyamula katundu ayenera kukhala ogwirizana bwino ndipo ayenera kukhala olimba komanso odalirika.

5. Ngati zikupezeka kuti choteteza kutayikira kwa madzi chili ndi phokoso losazolowereka, kutentha kukwera, kumva kosazolowereka kwa manja, ndi zina zotero, katswiri wamagetsi ayenera kupezeka nthawi yake kuti akawunikenso ndi kukonza.

6. Zoteteza kutayikira kwa madzi siziyenera kugwiritsidwa ntchito kwa nthawi yayitali ndipo nthawi zambiri siziyenera kugwiritsidwa ntchito kwa nthawi yoposa theka la chaka. Ngati pakufunika kupitiriza kugwiritsa ntchito zotetezazi, ziyenera kuyang'aniridwa mokwanira zisanagwiritsidwe ntchito.

Sizingatheke kusinthachodulira dera chotayikirandi soketi wamba.

Chifukwa chakuti soketi wamba yokha ndi chipolopolo chachitsulo komanso kutchinjiriza kwa mawaya amkati sikungathe kuteteza, kotero pamene kutayikira kukuchitika, magetsi amalowa m'thupi kudzera mu soketi, zomwe zimapangitsa ngozi yamagetsi.

Kugwiritsa ntchito magetsi mosamala n'kofunika kwambiri. Sikukhudza chitetezo chathu chokha, komanso anthu otizungulira. Ngati simusamala kugwiritsa ntchito magetsi poteteza, kusasamala pang'ono kungayambitse kugwedezeka kwa magetsi. Chifukwa chake, m'moyo watsiku ndi tsiku muyenera kukhala ndi chizolowezi chabwino cha magetsi otetezeka.

Chosinthira choteteza kutayikira kwa madzi chimatha kupereka chenjezo la moto wamagetsi, kuyang'anira moto wamagetsi, kutaya moto wamagetsi ndi ntchito zina. Chosinthira choteteza kutayikira kwa madzi chikhoza kuyikidwanso m'chipinda chogawa madzi chingathenso kuyikidwa pakufunika kulikonse kuti chiteteze malowo, ndipo chingachepetse bwino ngozi zomwe zingachitike chifukwa cha kutayikira kwa madzi.

Mukagwiritsa ntchitochodulira dera chotayikira, zinthu zotsatirazi ziyenera kukumbukiridwa:

1. Musanayike chotseka dera chotuluka madzi, ndikofunikira kuyang'ana mosamala ngati mawonekedwe ndi mizere yolumikizira ya chotseka dera chotuluka madzi ili bwino komanso ngati mawaya omwe agwiritsidwa ntchito akukwaniritsa zofunikira. Kuti muyese ngati mtengo wa zero sequence current wa chotseka dera chotuluka madzi uli mkati mwa mulingo wabwinobwino, sipayenera kukhala vuto lililonse lodziwika bwino chotseka dera chotuluka madzi chisanayambe kugwira ntchito.

2. Mukayika chotseka mafunde, muyenera kusamala kwambiri kuti fuse ndi mphamvu yake yamagetsi igwiritsidwe ntchito moyenera ndipo magetsi ayenera kudulidwa musanayang'ane choteteza mafunde. Zotseka mafunde siziyenera kugwiritsidwa ntchito ngati dera lakunja lalowa mchipindamo kapena ngati vuto la short-circuit lachitika.

3. Mukayika chotseka dera chotulutsa madzi, chotseka dera chiyenera kuyikidwa pamalo osalala komanso olimba ndipo chiyenera kukhazikika bwino kapena kuyikidwa pa zero.

4. Pambuyo poyika, chodulira magetsi chotuluka chiyenera kuyesedwa nthawi zonse podula magetsi, ndipo ngati sichingathe kulumikizidwa mkati mwa mphindi ziwiri, magetsi akhoza kulumikizidwanso.
