RCD Circuit Breaker: Chinhu Chinokosha Chekuchengetedza Chidimbu cheMagetsi Systems

TheResidual Current Device (RCD), zvakare anozivikanwa seaResidual Current Circuit Breaker (RCCB), yakakosha kune zvirongwa zvemagetsi. Inodzivirira kuvhunduka kwemagetsi uye inoderedza njodzi dzemoto wemagetsi. Mudziyo uyu inhengo inotapurika inotarisisa mafambiro emagetsi padunhu uye nekukasira kudzima magetsi kana paita kukanganisa, senge kana ikozvino yadonha pasi (pasi).

Nhanganyaya kuRCD Circuit Breakers

An RCD circuit breaker yakagadzirirwa kutarisa kuyera kwezvino kuyerera kuburikidza nemhenyu kana kwaakarerekera conductor mumaseketi emagetsi. Pasi pemamiriro ekushanda akajairika, ikozvino inoyerera kuburikidza nekondukita mhenyu inofanira kuenzana neyazvino inoyerera kuburikidza neakarerekera conductor. Nekudaro, kana kukanganisa kwasangana, senge mudziyo wakakuvadzwa kana wakanganisa waya, ikozvino inogona kudonha pasi, ichigadziraresidual current. Iyo RCD inoona kusaenzana uku uye inofamba dunhu, ichicheka magetsi mumamilliseconds.

Mhinduro dzechimbi-chimbi idzi dzinobatsira kudzivirira anogona kuvhundutswa nemagetsi pamwe nekudzikisira njodzi yemoto nemidziyo yemagetsi isina kunaka. Kushandiswa kweRCD kunonyanya kukosha munzvimbo dzine njodzi yakawedzerwa, yakadai senzvimbo dzakanyorova (semuenzaniso, dzimba dzekugezera, makicheni, uye nzvimbo dzekunze) nenzvimbo dzekuvaka.

Mashandiro eRCD Circuit Breakers Anoshanda

Kushanda kweRCD yakasara yazvino mudziyo iri pamusimboti wekuona kusaenzana pakati peiyo mhenyu (chikamu) uye mafungu asina kwaakarerekera. Mumagetsi anoshanda zvakakwana, iyo yazvino inopinda nema conductor mhenyu inofanirwa kudzoka kuburikidza neasina kwazvakarerekera conductor. Kana RCD ikaona kunyangwe kudiki kudonha kuri pasi (kazhinji 30 milliamps kana kushoma), inotsika dunhu.

Heino nzira iyoRCD circuit breaker mabasa:

1. Normal Operation: Mumamiriro ezvinhu akajairika, mararamiro ehupenyu uye asina kwaakarerekera akaenzana, uye RCD haitore chero chiito, ichibvumira maitiro emagetsi kushanda sezvinotarisirwa.
2. Kuonekwa kweLeakage Current: Kana pasi pakakanganisika kana kutadza kuvharisa mumudziyo kana waya, inobvinza kubva kune kondakita mhenyu kuenda pasi, zvichikonzera kusaenzana pakati pemhepo inorarama neyakarerekera.
3. Trigger Mechanism: Iyo RCD yedunhu mabreak anoramba achitarisa kuyerera kwazvino. Kana ikaona kubuda kwemvura (inosara ikozvino) inodarika zvikumbaridzo zvakafanotemerwa (kazhinji 30mA), mudziyo unotanga nzira yerwendo.
4. Rapid Disconnection: Mukati me milliseconds yekuona kukanganisa, RCD inobvisa simba remagetsi kune dhipatimendi rakakanganiswa, kudzivirira zvinogona kuitika magetsi kana moto wemagetsi.

Mhando dzeRCD Circuit Breakers

Kune marudzi akawanda eRCD circuit breakers, imwe neimwe inokodzera mashandisirwo chaiwo uye mazinga ekudzivirira:

1. Yakagadziriswa RCDs

Fixed RCDs akaiswa zvachose mumagetsi ekugovera mabhodhi uye anopa dziviriro kumatunhu akawanda mukati mechivako. Iwo akanakira kuchengetedza kuisirwa kwese kana nzvimbo dzakanangana mudzimba, mahofisi, nenzvimbo dzemaindasitiri.

2. Portable RCDs

Portable RCDs zvigadziriso zveplug-in zvinoshandiswa nemidziyo yega yega, inopa dziviriro yakawedzerwa paunenge uchishanda nemagetsi anotakurika. Midziyo iyi inonyanya kubatsira pakudzivirira kwenguva pfupi munzvimbo dzekuvaka, maworkshop, nenzvimbo dzekunze.

3. Socket-Outlet RCDs

Socket-outlet RCDs inosanganiswa muzvigadziko zvemagetsi uye inopa dziviriro kumidziyo yakabairwa mune izvo zvinotengeswa. Aya maRCD anowanzo shandiswa munzvimbo dzine njodzi huru yekuvhunduka kwemagetsi, senge yekugezera, makicheni, uye kuisirwa kunze.

Makiyi Mamiriro uye Mabhenefiti eRCD Circuit Breakers

RCD yakasara zvigadziriso zvazvino vanozivikanwa zvakanyanya nekuda kweakakosha maficha ekuchengetedza, kusanganisira:

1. Dziviriro Pamusoro peMagetsi Shock

Basa rekutanga reRCD kudzivirira kuvhunduka kwemagetsi. Nekuona uye kubvisa maseketi ane zvikanganiso zvepasi, iyo RCD inogona kudzivirira kukuvara kwakakomba kana kuuraya kunokonzerwa nekuvhunduka kwemagetsi.

2. Kudzivirira Moto

Kukanganisa kwemagetsi, kunyanya kukanganisa kwepasi, ndizvo zvinowanzokonzera moto wemagetsi.RCD circuit breakers kuderedza njodzi yemoto nekukurumidza kugura kukanganisa kwemagetsi kunoonekwa.

3. Fast Response Time

RCDs inopindura mukati me milliseconds yekuona kusaenzana mumagetsi emagetsi, kuderedza ngozi yekukuvara kana kukanganisa pfuma.

4. Kuchengetedzwa Kwakawedzerwa Munzvimbo Dzemvura

RCDs inokurudzirwa zvikuru kuti ishandiswe munzvimbo dzine mvura, dzakadai sedzimba dzekugezera, makicheni, uye nzvimbo dzekunze. Mvura inowedzera njodzi yetsaona dzemagetsi, uye RCD inopa imwe nhanho yekudzivirira munzvimbo idzi.

5. Kutevedza Mitemo Yekuchengetedza

Mitemo yakawanda yekuvaka uye mitemo yekuchengetedza magetsi inoda kushandiswa kweRCD yakasara zvigadziriso zvazvino mukuisa nekugadziridza kutsva. Kushandiswa kwavo kunovimbisa kutevedzera mitemo yekuchengetedza uye kunowedzera kuchengetedzwa kwese kwemagetsi masisitimu.

Zvishandiso zveRCD Circuit Breakers

RCD circuit breakers anoshandiswa mumhando dzakasiyana-siyana dzekuvandudza kuchengetedzwa uye kuderedza njodzi dzine chekuita nekukanganisa kwemagetsi. Mamwe maapplication akajairika anosanganisira:

1. Zvivakwa Zvekugara

Mudzimba,RCD circuit breakers kupa dziviriro yakakosha pakukanganisa kwemagetsi izvo zvinogona kutungamirira kumagetsi emagetsi kana moto. Dzinonyanya kukosha munzvimbo dzine mvura, dzakadai sedzimba dzekugezera uye makicheni, uko njodzi dzekuvhunduka dzakakwirira.

2. Commerce uye Industrial Installations

Munzvimbo dzekutengeserana uye mumaindasitiri,RCDs chengetedza vashandi kubva kunjodzi dzemagetsi, kunyanya munzvimbo dzine njodzi huru yetsaona dzemagetsi, senge nzvimbo dzekuvaka, maworkshop, uye mafekitori. Iwo anoshandiswawo kuchengetedza midziyo yakashata kubva mukukuvadzwa nekuda kwekukanganisa kwemagetsi.

3. Kunze uye Kwenguva Kuiswa

Portable RCDs anowanzoshandiswa mukuisa kwechinguvana, sepanzvimbo dzekuvaka, zviitiko zvekunze, kana panguva yekugadzira magetsi. Midziyo iyi inopa dziviriro yakakosha kana uchishanda nemidziyo yenguva pfupi kana inotakurika.

Kugumira kweRCD Circuit Breakers

ApoRCD yakasara zvigadziriso zvazvino dzinoshanda pakudzivirira kuvhundutswa kwemagetsi nemoto, dzine zvimwe zvadzisingakwanisi:

• Ivo Havapi Kuwedzeredza kana Kupfupika Kudzivirirwa Kwedunhu: RCD yakagadzirirwa kuona kukanganisa kwepasi uye kusara kwemhepo, asi haidziviriri kubva pakuremerwa kana mapfupi madiki. Kuti udzivirirwe zvakakwana, RCD inofanirwa kushandiswa pamwe chete nemamwe mabreaker edunhu kana fuse inopa kuwandisa uye kupfupika kwedunhu kudzivirira.
• Nuisance Tripping: Mune zvimwe zviitiko,RCD circuit breakers inogona kugumburwa zvisina basa nekuda kwekudonha kudiki ikozvino kana kukanganisa kwenguva pfupi. Zvisinei, betsero dzokotsekano dzinopfuura nokure kusagadzikana kwokumbogumburwa kunogumbura.
• Hapana Dziviriro Kupokana neMutsetse-kune-kwaNeutral Mhosva: RCDs inongodzivirira pakukanganisa kwepasi, kwete kukanganisa kunoitika pakati pevanorarama uye vasina kwavakarerekera conductors. Zvimwe zvidziviriro zvekudzivirira zvinodiwa pakuchengetedza dunhu rakazara.

Maitiro ekuyedza RCD Circuit Breakers

Kuongororwa nguva dzose kweRCD yakasara zvigadziriso zvazvino zvakakosha kuve nechokwadi chekushanda kwavo. Mazhinji maRCD anouya nebhatani rekuyedza rinoteedzera kukanganisa nekugadzira kudiki kusaenzana. Kana bhatani rekuedza radzvanywa, iyoRCD circuit breaker inofanira kugumburwa pakarepo, zvichiratidza kuti iri kushanda nemazvo. Zvinokurudzirwa kuedza maRCD kamwechete kamwe pamwedzi mitanhatu yega yega kuti ive nechokwadi chekuvimbika kwavo.

Mhedziso

The (RCD), inozivikanwawo se (RCCB), chinhu chakakosha chekuchengetedza chinopa dziviriro kubva kumagetsi nemoto wemagetsi. Nekutarisa maseketi emagetsi ekukanganisa kwepasi uye nekukasira kudzima magetsi kana paine chikanganiso,RCD circuit breakers kuita basa rakakosha mukusimudzira kuchengetedzwa kwekuisa magetsi. Kushandiswa kwavo kunonyanya kukosha munzvimbo dzine njodzi yakawedzerwa, yakadai semamiriro emvura uye nzvimbo dzekuvaka, uko njodzi yenjodzi dzemagetsi yakakwirira. Kune ani nani ari kutsvaga kuchengetedzwa kwemagetsi masisitimu avo, kuisa maRCD inhanho yakakosha mukuderedza njodzi nekuchengetedza zvese vanhu nemidziyo.
