Kutanga, ngationgororei basa relow voltage circuit breakeruye fuse mune yakaderera voltage magetsi edunhu:
1. Low Voltage Circuit Breakers
Inoshandiswa pakuremedza kuchengetedzwa kwemazuva ano pamagumo emagetsi emagetsi, nokuda kwekuchengetedzwa kwezvino pahunde uye kumagumo ebazi remitsara yekuparadzira, uye yekudzivirira ikozvino pamagumo ekugovera mitsetse.
Kana kuremerwa, kupfupika, kana kurasikirwa kwemagetsi kunoitika mumutsara, rwendo rwepakarepo rwe low-voltage circuit breaker runocheka simba rekuchengetedza kuchengetedza tambo.
Residual Current Circuit BreakerInoshandiswa kune Personal Shock Dziviriro
2. Mafusi
Iyo inoshandiswa pakuremerwa kwekudzivirira kwemutoro ikozvino mumutsara uye pfupi dunhu redziviriro pakati pechikamu nechikamu uye hukama pasi.
Fuse mudziyo unodzivirira.Kana iyo yazvino inodarika kukosha kwakatarwa uye ichipfuura nenguva yakakwana, iyo inonyungudika, uye dunhu rakabatana naro rinobviswa, iro rinopa kuchengetedzwa kwekuremerwa kana kupfupika kwekudzivirira kwedunhu nemidziyo.
Kuburikidza nekuongorora kwakapfava, zvinogona kuzivikanwa kuti macircuit breaker nemafuse anofanirwa kuiswa mune yakaderera voltage magetsi maturusi, angave ekushandiswa kwemaindasitiri kana kushandiswa kwemba.
Ko hunyanzvi hwemagetsi vese vanoziva: Basa remagetsi rinofanira kunyatsoenderana ne "Low Voltage Electrical Device Regulations".Kune zvitsauko zviviri mu "Low Voltage Electrical Device Regulations" iyo inonyatso gadzira zvimisikidzo zvemain switch (circuit breaker) uye fuse.
Iko kufananidzwa kwedunhu rinotyora uye fuse uye kufananidzwa kwewaya kunofanirwawo kutariswa kune chaiyo yedunhu mudziyo.
Iyo yakatemerwa fuse ikozvino yefuse yemudziyo mudunhu inofanirwa kunge yakakura kupfuura kana kuenzana ne1.2 kusvika 1.3 nguva dzeiyo yakayerwa ikozvino yedunhu rinotyora.
Iyo yakanyunguduka ikozvino yefuse isingasviki 0.8 nguva yeakachengeteka ikozvino yewaya conductor.
Kazhinji kutaura, kunyunguduka kwefuse kunofanirwa kunge kwakakura kupfuura yakayerwa ikozvino yedunhu rinotyora uye kushoma pane yakachengeteka kutakura kugona kwekondakita.
Iyo yakatemerwa ikozvino yedunhu breaker inofanira kunge yakakura kupfuura kana yakaenzana neiyo mutsara wemazuva ano, uye mutsara wemutoro wezvino unofanirwa kuve 1.2 nguva yakawanda semutsetse wemutsetse ikozvino.Inogonawo kugadzirisa mutsara wemutsara zvakakodzera maererano nemhando yemutoro wemutsara, zvakadai sekupisa kwemagetsi.Asi iyo yakayerwa ikozvino yedunhu breaker inofanira kunge iri shoma pane fuse melt current.
Mukuwedzera, kune michina yakawanda yedunhu isina fuse, iyo isina kuchengeteka uye isina kururama.Kana pane kukanganisa mumutsara, zviri nyore kwazvo kukonzera moto.Kare tsaona dzemoto, mafizi aisaiswa kana kukanganiswa.Pane zvidzidzo zvakawanda zvinofanira kudzidzwa.Naizvozvo, fuse uye mabreaker edunhu anofanirwa kuiswa mukushongedza kwemba.Usambove usina hanya uye wakachengeteka kutanga.
