KunzwisisaRCCBKuiswa: Chinhu Chinokosha Pakuchengetedza Magetsi
Munyika yanhasi, midziyo yemagetsi yave chikamu chakakosha chehupenyu hwedu hwezuva nezuva, uye kuve nechokwadi chekuti midziyo yemagetsi yakachengeteka kwakakosha. MaResidual current circuit breakers (RCCBs) ndeimwe yemidziyo inoshanda zvakanyanya yakagadzirirwa kusimudzira kuchengetedzeka kwemagetsi. Chinyorwa chino chinopa ruzivo rwakadzama pamusoro pekushanda, kukosha uye mashandisirwo emidziyo yeRCCB.
Chii chinonzi mudziyo weRCCB?
Mudziyo weRCCB, unozivikanwawo semudziyo wemagetsi unoramba uripo (RCD), mudziyo wemagetsi unovhura dunhu pese paunoona kusawirirana pakati pewaya dziri mhenyu nedzisina kusimba. Kusawirirana uku kunogona kuitika nekuda kwezvikonzero zvakasiyana-siyana, zvakaita sekukanganisa kwewaya kana kusangana newaya dziri mhenyu netsaona. MaRCCB akagadzirwa kudzivirira kuvhunduka kwemagetsi uye kuderedza njodzi yemoto wemagetsi, zvichiita kuti ave chikamu chakakosha chemagetsi emazuva ano.
RCCB inoshanda sei?
Musimboti wekushanda kwemudziyo weRCCB ndewekuona magetsi akasara. Unogara uchitarisa magetsi anofamba nepakati pewaya dziri mhenyu nedzisina kusimba. Kazhinji, magetsi anopinda nekubuda anofanira kunge akaenzana. Zvisinei, kana magetsi akabuda (zvichida nekuda kwekutadza kwemidziyo kana kuti vashandi vanosangana newaya dziri mhenyu), RCCB ichaona kusawirirana uku.
Kana RCCB ikanzwa mutsauko, inovhura circuit nekukurumidza, kazhinji mukati memamirisekonzi makumi matatu. Mhinduro iyi inokurumidza inoderedza zvakanyanya njodzi yekuvhunduka kwakanyanya kwemagetsi uye kufa kunogona kuitika. Mudziyo uyu unowanikwa muzvikamu zvakasiyana-siyana, zvinowanzo tangira pa30 mA yekudzivirira munhu kusvika pazvikamu zvepamusoro zvekudzivirira michina.
Kukosha kwemudziyo weRCCB
Kukosha kwekuisa RCCB hakufanirwe kutaurwa zvakanyanya. Dzinoita basa rakakosha mukuona kuti magetsi akachengeteka munzvimbo dzekugara, dzemabhizinesi nedzemaindasitiri. Heano mamwe ezvikonzero zvikuru nei RCCB ichikosha:
1. Dziviriro kubva kuMagetsi: Basa guru reRCCB nderekudzivirira vanhu kubva kumagetsi. Nekubvisa circuit kana paine chikanganiso, njodzi yekukuvara kana kufa inoderedzwa.
2. Kudzivirira Moto: Kukundikana kwemagetsi kunogona kukonzera kupisa kwakanyanya uye pakupedzisira kukonzera moto. Nekuona nekukanganisa maseketi asina kunaka, maRCCB anobatsira kudzivirira moto wemagetsi, kudzivirira pfuma nehupenyu.
3. Tevedzerai mitemo: Nyika zhinji dzine mitemo yakasimba yekuchengetedza magetsi inorayira kushandiswa kweRCCBs mune dzimwe nzvimbo. Kutevedzera mitemo iyi hakungovimbisi chete kuchengetedzeka asiwo kudzivirira migumisiro yemutemo.
4. Rugare Rwepfungwa: Kuziva kuti RCCB iripo kunogona kupa varidzi vedzimba nevaridzi vemabhizinesi rugare rwepfungwa. Izvi zvinovabvumira kushandisa midziyo yemagetsi vasinganetseki nezvenjodzi dzingangoitika.
Kushandiswa kwemudziyo weRCCB
Midziyo yeRCCB inogona kushandiswa mumhando dzakasiyana siyana, kusanganisira:
- KUVAKA KWEMAHARA: Mudzimba, maRCCB anowanzoiswa mumapaneru emagetsi kudzivirira macircuit anobatidza masoketi, mwenje nemidziyo.
- NZVIMBO YEKUTENGESA: Mahofisi, zvitoro nedzimwe nzvimbo dzekutengeserana dzinoshandisa RCCB kuona kuchengetedzeka kwevashandi vavo nevatengi.
- Nzvimbo Yemaindasitiri: Mumafekitori nemafekitori emaindasitiri, maRCCB akakosha kuchengetedza michina nemidziyo uye kuona kuchengetedzeka kwevashandi.
- KUISA PANZE**: RCCB inoshandiswawo mukuisa magetsi panze uko njodzi yekubatidzwa nemagetsi yakanyanya, senge mwenje webindu nemaseketi edziva rekushambira.
Muchidimbu
Midziyo yeRCCB chikamu chakakosha chehurongwa hwemazuva ano hwekuchengetedza magetsi. RCCB dzinosimudzira kuchengetedzeka munzvimbo dzekugara, dzekutengeserana uye dzemaindasitiri nekudzivirira kubva mukuvhunduka kwemagetsi uye kudzivirira moto wemagetsi. Sezvo tekinoroji ichiramba ichichinja, kukosha kwekuisa RCCB mukuisa magetsi kuchawedzera, kuve nechokwadi chekuti kuchengetedzeka kunoramba kuri chinhu chakakosha munyika yedu ine magetsi akawanda.
