Choyamba, tiyeni tiwunike ntchito yalow voltage circuit breakerndi fuse mu low voltage magetsi circuit:

1. Low Voltage Circuit Breakers

Amagwiritsidwa ntchito ponyamula chitetezo chapano kumapeto kwamagetsi okwana, poteteza chitetezo chapano pa thunthu ndi malekezero a nthambi za mizere yogawa, komanso chitetezo chapano kumapeto kwa mizere yogawa.

Pakachulukirachulukira, kuzungulira pang'ono, kapena kutayika kwamagetsi pamzere, ulendo wanthawi yomweyo wamagetsi otsika amadula magetsi kuti ateteze chitetezo cha chingwecho.

Chotsalira Chatsopano Chozungulira CircuitAmagwiritsidwa Ntchito Poteteza Munthu Wowopsa

2. Mafusi

Amagwiritsidwa ntchito poteteza katundu wambiri pamzere ndi chitetezo chafupipafupi pakati pa gawo ndi gawo ndi malo achibale.

Fuse ndi chipangizo choteteza.Pakalipano ikadutsa mtengo wokhazikika ndikudutsa nthawi yokwanira, kusungunuka kumasungunuka, ndipo dera lomwe limalumikizidwa nalo limachotsedwa, lomwe limapereka chitetezo chochulukirapo kapena chitetezo chachifupi cha dera ndi zida.

Kupyolera mu kusanthula kosavuta, zitha kudziwika kuti zowononga ma circuit ndi ma fuse ziyenera kuikidwa pazida zamagetsi zotsika, kaya zogwiritsidwa ntchito m'mafakitale kapena zapakhomo.

Kodi akatswiri amagetsi onse akudziwa: Ntchito yamagetsi iyenera kutsatira kwambiri "Malamulo Otsika Pazida Zamagetsi".Pali mitu iwiri mu "Low Voltage Electrical Device Regulations" yomwe imapanga mwapadera kuyika kwa main switch (circuit breaker) ndi fuse.

Kufananiza kwa wophwanyira dera ndi fusesi komanso kufananiza kwa waya kuyeneranso kuyang'aniridwa pa chipangizo chenichenicho.

Ma fuse ovoteledwa pakalipano ya fuyusi ya chipangizocho muderali iyenera kukhala yayikulu kuposa kapena yofanana ndi nthawi 1.2 mpaka 1.3 yanthawi yovotera ya woyendetsa dera.

Kusungunuka kwa fuseji ndi nthawi zosakwana 0,8 za nthawi yotetezeka ya woyendetsa waya.

Nthawi zambiri, mphamvu yosungunuka ya fuseyi iyenera kukhala yayikulupo kuposa momwe kondakitala amanyamulira komanso kuchepera mphamvu yonyamula yotetezeka ya kondakitala.

Mphamvu yamagetsi yamagetsi yamagetsi iyenera kukhala yayikulu kuposa kapena yofanana ndi mzere wapano, ndipo kuchuluka kwa mzere wapano kuyenera kukhala nthawi 1.2 kuposa kuchuluka kwa mzere wapano.Ikhozanso kusintha katundu wa mzere moyenera malinga ndi chikhalidwe cha katundu wa mzere, monga kutentha kwa magetsi.Koma mphamvu yamagetsi yamagetsi yamagetsi iyenera kukhala yocheperako kuposa fuse yosungunuka.

Kuphatikiza apo, pali zida zambiri zamagawo opanda ma fuse, omwe ali otetezeka komanso olakwika.Pakakhala cholakwika pamzere, zimakhala zosavuta kuyambitsa moto.M'mbuyomu ngozi zamoto, ma fuse sanali kuyikidwa kapena kuyikidwa molakwika.Pali maphunziro ambiri oti aphunzire.Chifukwa chake, ma fuse ndi zowononga madera ziyenera kukhazikitsidwa muzokongoletsa kunyumba.Musakhale osasamala ndi otetezeka poyamba.
