Chii chinonzi RCBO?
RCBO inomirira Residual Current Breaker ine Over-Current protection.Iyo RCBO inosanganisa kushanda kweMCB uye RCD/RCCB.Kana paine kuvuza kwazvino, RCBO inofamba dunhu rese.Nekuda kweizvozvo, zvemukati magineti / zvinopisa wedunhu breaker zvikamu zvinogona kutsika mudziyo wemagetsi kana dunhu raremerwa.
1. Residual Current, kana Earth Leakage - Inoitika kana pakaita netsaona kuputsika kwedunhu kuburikidza nemagetsi asina kunaka ewaya kana tsaona dzeDIY dzakadai sekuboora netambo paunenge uchiisa chiredzo chepikicha kana kucheka netambo ine lawn mower.Muchiitiko ichi magetsi anofanirwa kuenda kumwe uye kusarudza nzira iri nyore kufamba nemuchina chekuchenura kana kudhiraivha kuenda kumunhu zvichikonzera kuvhunduka kwemagetsi.
2. Over-Curent inotora mafomu maviri:
a.Overload - Inoitika kana midziyo yakawandisa iri kushandiswa padunhu, ichidhirowa huwandu hwesimba rinopfuura kugona kwetambo.
b.Short Circuit - Inoitika kana paine hukama hwakananga pakati pevanogara uye vasina kwavakarerekera conductors.Pasina kupokana kunopihwa neakajairika wedunhu kuperera, magetsi emagetsi anomhanya achitenderedza dunhu muchiuno uye anowedzera amperage nezviuru zvakapetwa mumamilliseconds uye ane njodzi zvakanyanya kupfuura Overload.
Ipo RCCB yakagadzirirwa chete kudzivirira kubva mukudonha kwepasi uye MCB inodzivirira chete kubva kune-izvino, RCBO inodzivirira kubva kumarudzi ese ekukanganisa.
Muhupenyu chaihwo, zvinhu zvemagetsi zvakaita semasara emagetsi emagetsi (anowanzo zivikanwa seakageji switch) anoshandiswa munenge munzvimbo dzese dzine magetsi.Inonyanya kushandiswa kuona iyo yakasara ikozvino, enzanisa yakasara kukosha kwezvino nereferensi kukosha, uye bvisa iyo huru yedunhu kusangana kana yakasara kukosha kwezvino inodarika kukosha kwereferensi.Kana magetsi ega ega kana grid leakage yazvino ichidarika kukosha kwakatarwa, iyo yasara yazvino inotyora yedunhu inogona kukurumidza kudzima magetsi asina kunaka munguva pfupi, kudzivirira kuchengetedzwa kwemidziyo yemunhu neyemagetsi, uye panguva imwechete kudzivirira kuremedza kana kupfupika dunhu remutsara uye mota, uye zvakare Inogona kushandiswa kune isingawanzo chinjika mitsara uye isingawanzo tangi yemotor, uye inoshandiswa zvakanyanya magetsi mudziyo mukugadzira uye hupenyu.
1. Iyo leakage yekudzivirira relay inoreva kudonha kwekudzivirira mudziyo une basa rekuona uye kutonga leakage ikozvino, asi haina basa rekucheka nekubatanidza dunhu guru.Iyo leakage yekudzivirira relay inoumbwa ne zero-sequence transformer, kuburitsa uye yekubatsira kubata kune inobuda chiratidzo.Iyo inogona kushandira pamwe neye otomatiki switch yeazvino yakakwira seyekudzivirira kwakawanda kweyakaderera-voltage magetsi gidhi kana kuvuza, kudzika kana kuvhara kwekutarisa kudzivirira kwemugwagwa mukuru.Kana paine kuvuza ikozvino mudunhu guru, sezvo iyo yekubatsira yekubatanidza uye kuparadzaniswa kuburitswa kweiyo main circuit switch yakabatana munhevedzano kuti iite dunhu, iyo yekubatsira yekubatanidza yakabatana nekuparadzanisa kuburitswa uye inobvisa mhepo switch, AC contactor, etc. loop.Vabatsiri vanobatika vanogona zvakare kubatanidzwa kune inonzwika uye mwenje masaini madhizaini kuti abudise inovuza alarm chiratidzo kuratidza mamiriro ekudzivirira emutsara.2. Iyo leakage yekudzivirira switch inoreva kuti haingogone kuvhura kana kudzima dunhu guru semamwe mabreaker edunhu, asiwo ine basa rekuona uye kutonga leakage ikozvino.Kana kuvuza kana kukuvara kwekudzivirira kunoitika munharaunda huru, iyo yekuvuza yekudzivirira switch inogona kuve yakavakirwa paIyo switching chinhu chinotenderedza dunhu guru kana kudzima semhedzisiro yemutongo.Inoshanda pamwe nemafuse uye thermal relays kuti igadzire yakazara inoshanda yakaderera-voltage switch element.
