Circuit Breaker RCD: Mhinduro Yekudzivirira Kaviri

KunzwisisaMacircuit Breakers neRCDs: Zvikamu Zvakakosha zveKuchengetedzwa kweMagetsi

Munyaya dzekuchengetedza magetsi, michina miviri mikuru inoonekwa: macircuit breakers nemidziyo yemagetsi inosara (RCDs). Zvese zvinoita basa rakakosha mukuchengetedza simba remagetsi uye, chinonyanya kukosha, hupenyu hwevanhu. Blog rino rinotsanangura mashandiro, mutsauko, uye kukosha kwemidziyo iyi kuti ipe varidzi vedzimba, mainjiniya emagetsi, uye chero ani zvake anofarira kuchengetedzeka kwemagetsi kunzwisisa kwakazara.

Chii chinonzi circuit breaker?

Circuit breaker iswitch yemagetsi inongoerekana yagadzirwa kuchengetedza circuit yemagetsi kubva mukukuvadzwa kunokonzerwa nekuwanda kwemagetsi kana short circuit. Basa rayo guru nderekumisa kuyerera kwemagetsi mushure mekuona chikanganiso. Kusiyana nemafuse, anoshanda kamwe chete uye anofanira kutsiviwa, macircuit breaker anogona kudzoserwa patsva (nemaoko kana otomatiki) kuti atangezve kushanda kwakajairika.

Rudzi rwemuchina wekupwanya dunhu

1. Miniature Circuit Breaker (MCB): MCB inoshandiswa mumacircuit ane voltage shoma kudzivirira overloads uye short circuits. Inowanzo kuwanikwa muzvivakwa zvekugara uye zvemabhizinesi.
2. Molded Case Circuit Breaker (MCCB): MCCB yakakodzera kushandiswa nesimba rakawanda, inopa magadzirirwo ekufamba anogadziriswa, uye inoshandiswa munzvimbo dzemaindasitiri.
3. Ground Fault Circuit Interrupter (GFCI): GFCI dzakagadzirirwa kudzivirira zvikanganiso zvepasi uye dzakakosha munzvimbo dzine hunyoro hwakawanda dzakadai sedzimba dzekugezera nemakicheni.

Chii chinonzi RCD?

Mudziyo weResidual Current (RCD), unozivikanwawo seGround Fault Circuit Interrupter (GFCI) mune dzimwe nzvimbo, mudziyo unovhura dunhu remagetsi nekukurumidza kudzivirira kukuvara kwakanyanya kubva mukuvhunduka kwemagetsi kwenguva refu. Unoshanda nekuona kusawirirana pakati pewaya dziri mhenyu nedzisina kusimba. Kana magetsi ari kuyerera newaya dziri mhenyu akasiyana nemagetsi ari kuyerera newaya dzisina kusimba, RCD inogumburwa, ichibvisa magetsi.

Rudzi rweRCD

1. RCD yakagadziriswa: Yakaiswa muyuniti yemutengi (bhokisi refuse) uye inodzivirira maseketi akawanda.
2. Socket RCD: Yakavakwa muma socket akajairwa kuti ipe dziviriro kumidziyo yakabatana.
3. RCD inotakurika: Inoiswa muchikamu chero chipi zvacho chemagetsi, ichidzivirira chero mudziyo wakabatanidzwa mairi.

Musiyano Pakati peCircuit Breaker neRCD

Kunyange zvazvo zvishandiso zvose zviri zviviri zvakakosha pakuchengetedzwa kwemagetsi, zvinoshanda zvakasiyana:

- Basa: Circuit breaker inodzivirira kubva pa overcurrent uye short circuits, ukuwo RCD inodzivirira kubva pa ground failures uye electric shock.
- KUSHANDA: Circuit breaker inodonha kana magetsi adarika mwero wakatarwa uye RCD inodonha kana paine kusawirirana pakati pemagetsi aripo uye asina kusimba.
- Kugadzirisazve: Midziyo yese inogona kugadziriswazve mushure mekugumburwa, asi chikonzero cherwendo chinofanira kuzivikanwa uye kugadziriswa usati wagadzirisazve.

Kukosha kweVapanduki veDunhu neRCDs

1. Kudzivirira Moto weMagetsi: Zvidziviriro zvemagetsi zvinodzivirira kupisa zvakanyanya uye moto unogona kuitika nekubvisa magetsi akawandisa.
2. Dzivirirai Midziyo Yemagetsi: Midziyo iyi inodzivirira midziyo yemagetsi kubva mukukuvadzwa nekuvhiringidza circuit panguva yekukanganisa.
3. INOPONESA HUPENYU: MaRCD anonyanya kukosha mukudzivirira kuvhunduka kwemagetsi kunouraya. Anonyanya kukosha munzvimbo dzine mvura, izvo zvinogona kuwedzera njodzi yekuvhunduka kwemagetsi.

Muchidimbu

Kunzwisisa basa uye musiyano uripo pakati pemacircuit breakers nemaRCDs kwakakosha pakuchengetedza kuchengetedzeka kwemagetsi munzvimbo chero ipi zvayo. Macircuit breakers anodzivirira kubva pakukwira kwemagetsi uye mapfupi, nepo maRCD achipa dziviriro yakakosha kubva pakuvhunduka kwemagetsi. Pamwe chete, zvishandiso izvi zvinoumba kuchengetedzwa kwakazara kunoita kuti masisitimu emagetsi ashande zvakachengeteka uye zvinobudirira. Ungave uri muridzi wemba, nyanzvi yemagetsi, kana mumwe munhu anongoda kuchengetedzeka kwemagetsi, kunzwisisa mashandiro anoita zvishandiso izvi uye kuti nei zvichikosha kunogona kukubatsira kuita sarudzo dzakachenjera uye kuchengetedza nzvimbo yakachengeteka yekugara kana yekushanda.
