Chotsalira Chotsegula Dera: Chitsimikizo cha Magetsi Otetezeka

KumvetsetsaZotsalira za Circuit Breakers: Buku Lotsogolera Lonse

Pankhani ya chitetezo chamagetsi, ma residual current circuit breakers (RCBs) amagwira ntchito yofunika kwambiri poteteza anthu ndi katundu ku zolakwika zamagetsi. Chipangizochi chapangidwa kuti chizindikire kusalingana kwa mphamvu zamagetsi ndikutsegula dera pamene vuto lapezeka, motero kupewa zoopsa zomwe zingachitike monga kugwedezeka kwa magetsi ndi moto. M'nkhaniyi, tiwona bwino momwe ma earth leak circuit breakers amagwirira ntchito, ubwino wawo, ndi momwe amagwiritsidwira ntchito.

Kodi chotsegula dera lotayira madzi n'chiyani?

Chotsekera magetsi chotsalira, chomwe nthawi zambiri chimatchedwa chipangizo chamagetsi chotsalira (RCD) kapena chotsekera magetsi chotsalira (RCCB), ndi chipangizo chamagetsi chomwe chimayang'anira magetsi mu dera lamagetsi. Chimayerekeza nthawi zonse magetsi omwe akuyenda kudzera mu mawaya amoyo ndi osalowerera. Nthawi zambiri, magetsi mu mawaya onse awiri ayenera kukhala ofanana. Komabe, ngati vuto lachitika, monga dera lalifupi kapena munthu wina akakhudza waya wamoyo, magetsi amatha kusalinganika. RCB imazindikira kusalinganika kumeneku ndikutsegula dera mwachangu, nthawi zambiri mkati mwa ma milliseconds ochepa.

Kodi chodulira dera chotuluka madzi chimagwira ntchito bwanji?

Kugwira ntchito kwa zotsekera ma circuit zotuluka m'nthaka kumadalira mfundo ya kulowetsedwa kwa maginito. Chipangizochi chili ndi chitsulo chokhala ndi ma coil awiri: chimodzi cha waya wamoyo ndi china cha waya wopanda mbali. Pamene ma current ali bwino, maginito omwe amapangidwa ndi ma coil awa amasiyana. Komabe, ngati pali leakage current (kusonyeza vuto), maginito sadzaleka, zomwe zimapangitsa kuti njira yosinthira maginito igwetse dera.

Ma RCB ambiri amapangidwira kuti agwe pa mphamvu inayake yotulutsa madzi, nthawi zambiri kuyambira 30 mA kuti adziteteze payekha mpaka 100 mA kapena kuposerapo kuti ateteze zida. Kuzindikira kumeneku kumatsimikizira kuti ngakhale kutayikira pang'ono komwe kungayambitse kugwedezeka kwa magetsi kumadziwika mwachangu ndikuthetsedwa.

Ubwino wogwiritsa ntchito chotsukira mafunde cha earth leakage

1. Chitetezo Chowonjezereka: Phindu lalikulu la RCB ndi chitetezo chowonjezereka chomwe chimapereka. Mwa kutseka dera ngati pakhala vuto, chiopsezo cha kugwedezeka kwa magetsi ndi moto wamagetsi chikhoza kuchepetsedwa kwambiri.

2. Chitetezo cha Zipangizo: Kuwonjezera pa kuonetsetsa kuti miyoyo ya anthu ndi yotetezeka, RCB imathanso kuteteza zipangizo zamagetsi ndi zida ku kuwonongeka komwe kumachitika chifukwa cha zolakwika zamagetsi.

3. KUTSAMIKIZIRA MALAMULO: Ma code ambiri achitetezo chamagetsi ndi ma code omangira nyumba amafuna kuti pakhale ma residual circuit breakers m'nyumba ndi m'mabizinesi. Kugwiritsa ntchito RCB kumatsimikizira kuti miyezo imeneyi ikutsatira malamulo.

4. Mtendere wa Mumtima: Kudziwa kuti chotchingira mafunde chayikidwa kungapatse eni nyumba ndi eni mabizinesi mtendere wa mumtima, zomwe zingawathandize kugwiritsa ntchito zida zamagetsi popanda kuda nkhawa ndi zoopsa zomwe zingachitike.

Kugwiritsa ntchito chotsukira dera chotulutsa madzi cha earth leakage

Zothyola ma circuit breaker a Earth leakage amagwiritsidwa ntchito kwambiri pazochitika zosiyanasiyana, kuphatikizapo:

- KUMANGA NYUMBA ZOKHALA: Ma RCB nthawi zambiri amaikidwa m'nyumba kuti ateteze ku kugundana kwa magetsi, makamaka m'malo omwe madzi amalowa m'malo monga zimbudzi ndi khitchini.

- Malo Ogulitsa: Mabizinesi amagwiritsa ntchito RCB kuti atsimikizire chitetezo cha antchito ndi makasitomala, komanso kuteteza zida zobisika.

- Malo Ogwirira Ntchito Zamakampani: M'mafakitale ndi m'malo ogwirira ntchito, ma RCB ndi ofunikira kuteteza makina ndikuwonetsetsa kuti ogwira ntchito m'malo omwe ali pachiwopsezo chachikulu ali otetezeka.

Powombetsa mkota

Mwachidule, zotchingira magetsi zotayira madzi m'nthaka ndi gawo lofunika kwambiri pamagetsi amakono, zomwe zimateteza kwambiri ku zolakwika zamagetsi. Kutha kwake kuzindikira kusalingana komwe kulipo ndikuchotsa magetsi mwachangu kumapangitsa kuti ikhale chida chofunikira kwambiri chotetezera m'nyumba, mabizinesi ndi m'malo opangira mafakitale. Pomvetsetsa kufunika ndi ntchito za zotchingira magetsi zotayira madzi m'nthaka, anthu ndi mabungwe amatha kuchitapo kanthu mwachangu kuti akonze chitetezo chamagetsi komanso kutsatira malamulo. Kuyika ndalama mu RCB sikungokhudza kutsatira malamulo; ndi kudzipereka ku chitetezo ndi moyo wabwino m'dziko lathu lomwe likugwiritsa ntchito magetsi ambiri.
