Circuit Breaker neRCD: Vimbiso yeSimba Rakachengeteka

Macircuit Breakers neRCDsKunzwisisa Basa Ravo Mukuchengetedzwa Kwemagetsi

Munyika yekuchengetedzeka kwemagetsi, zvinhu zviviri zvakakosha zvinowanzo shandiswa: macircuit breaker nemidziyo yemagetsi inosara (RCDs). Kunyangwe zvese zvakagadzirirwa kuchengetedza macircuit nekudzivirira njodzi, zvinoshanda zvakasiyana uye zvakagadzirirwa mabasa chaiwo. Kunzwisisa basa remacircuit breaker neRCDs kwakakosha kune chero ani zvake anobatanidzwa mukuisa, kugadzirisa kana kuchengetedzeka kwemagetsi.

Chii chinonzi circuit breaker?

Circuit breaker iswitch yemagetsi inongoerekana yagadzirwa kudzivirira circuit yemagetsi kubva mukukuvadzwa kunokonzerwa nekuwanda kwemagetsi kana short circuit. Kana magetsi ari kufamba necircuit akadarika mwero wakatarwa, circuit breaker inomisa kufamba kwemagetsi, zvichiita kuti "circuit" ivhurwe. Izvi zvinodzivirira system yemagetsi nemidziyo yakabatana nekudzivirira kupisa zvakanyanya uye moto unogona kuitika.

Kune mhando dzakawanda dzemacircuit breakers, dzinosanganisira:

1. Miniature Circuit Breaker (MCB): Inoshandiswa mukushandiswa kwemagetsi mashoma kudzivirira kubva pakuwanda kwemagetsi uye mapfupi.
2. Residual Current Circuit Breaker (RCCB): Midziyo iyi inoona kusawirirana kwemagetsi uye inopwanya dunhu kudzivirira kuvhunduka kwemagetsi.
3. Chinopwanya Mwenje (ELCB): Kufanana neRCCB, ELCB inodzivirira kubva pakukanganiswa kwepasi uye kubuda kwemvura.

Chii chinonzi RCD?

Chishandiso cheResidual Current Device (RCD), chinozivikanwawo seResidual Current Circuit Breaker (RCCB), chishandiso chekuchengetedza chinovhura dunhu pese painoona kusawirirana kwemagetsi pakati pemaconductor ari mupenyu neeasina kusimba. Kusawirirana uku kunoitika kana paine kutadza kushanda zvakanaka, senge kana munhu akabata waya iri mhenyu netsaona, zvichikonzera kubatwa nemagetsi kana kubatwa nemagetsi.

MaRCD akagadzirwa kuti ashande nekukurumidza (kazhinji mukati me30 milliseconds) kudzivirira kukuvara kwakanyanya kana kufa. Anonyanya kukosha munzvimbo dzine mvura dzakadai sedzimba dzekugezera nemakicheni, uko njodzi yekuvhundutswa nemagetsi yakanyanya. MaRCD anogona kuiswa semidziyo yega kana kuiswa mumacircuit breakers kuti ape dziviriro mbiri.

Kukosha kwemacircuit breakers neRCDs

Macircuit breaker nemaRCD anoita basa rakakosha mukuona kuchengetedzeka kwemagetsi. Macircuit breaker anodzivirira kubva pakuwanda kwemagetsi uye mashort circuit, ukuwo maRCD achitarisa pakudzivirira kuvhunduka kwemagetsi nekuona kubuda kwemagetsi. Pamwe chete vanoumba sisitimu yakakwana yekuchengetedza inoderedza njodzi dzemagetsi.

1. Dziviriro pamoto: Macircuit breaker anodzivirira kupisa zvakanyanya uye moto unogona kukonzerwa nekuwanda kwecircuit. Anogona kugumburwa kana zvichidikanwa, achidzivirira waya nemidziyo kubva mukukuvadzwa.

2. Dziviriro paKuvhunduka: MaRCD akakosha pakudzivirira vanhu kubva pakuvhunduka nemagetsi. Nekukurumidzira kubvisa circuit kana paine chikanganiso, anogona kuderedza zvakanyanya njodzi yekukuvara zvakanyanya kana kufa.

3. KUTEVEDZERA MITEMO YEMAKODHI: Makodhi mazhinji ekuchengetedza emagetsi anoda kuti pave nema "circuit breakers" uye maRCD mudzimba dzekugara nedzemabhizinesi. Kutevedzera mitemo hakungovimbisi chete kuchengetedzeka asiwo kunodzivirira varidzi vepfuma kubva pamhosva dzemutemo.

Muchidimbu

Muchidimbu, macircuit breakers ne earth leak protectors zvinhu zvakakosha mukuchengetedza magetsi. Macircuit breakers anodzivirira kubva pakuzara kwemagetsi uye mashort circuit, nepo maRCD achidzivirira zvikuru kubva pakuvhunduka kwemagetsi. Kunzwisisa mashandiro uye kukosha kwemidziyo iyi kwakakosha kune chero munhu anoshanda nesimba remagetsi. Nekuona kuti macircuit breakers neRCDs akaiswa uye akachengetedzwa zvakanaka, tinogona kugadzira nharaunda yakachengeteka kwatiri nevamwe uye kuderedza njodzi dzemagetsi mudzimba dzedu nenzvimbo dzebasa.
