Mhepo switch (inozonzi "air switch", pano isu tinonyatso taura kune GB10963.1 yakajairwa yedunhu redunhu) chinhu chekudzivirira chinonyanya tambo, mubvunzo mukuru ndewekuti "sei switch yemhepo ichifanira kuseta kuchengetedzwa kwekuremerwa uye kuchengetedzwa kwedunhu pfupi" inogona kuwedzerwa kune "nei tambo ichifanira kuseta yakawandisa kuchengetedza uye pfupi dunhu kuchengetedzwa panguva imwe chete"
1.Chii chinonzi overcurrent?
Iyo loop ikozvino yakakura kudarika yakatarwa kutakura ikozvino ye loop conductor yakawandisa, kusanganisira yakawandisa ikozvino uye pfupi-yedunhu ikozvino.
2.the cable overload protection
Dunhu remagetsi nekuda kwekuwanda kwemidziyo yemagetsi kana midziyo yemagetsi pachayo inoremedza (senge mota mekichani mutoro wakakurisa) uye zvimwe zvikonzero, kukosha kwazvino kwakawanda kwakayerwa ikozvino kwedunhu, mhedzisiro ndeyekuti tembiricha yekushandisa tambo inodarika. kukosha kunobvumidzwa, iyo tambo yekuvharisa yakamhanyisa kuderera, kupfupisa hupenyu.Semuenzaniso, kune PVC tambo, yakanyanya kubvumidzwa tembiricha yekushanda kwenguva yakareba ndeye 70 ° C, uye inobvumidzwa tembiricha yenguva pfupi kana iri pfupi pfupi haipfuure 160 ° C.
Iyo tambo inogona kumira kune imwe yakawandisa yazvino kune imwe nguva yenguva, asi iyo nguva inofanirwa kushomeka.Kana iyo yakawandisa ikozvino inotora nguva yakareba, iyo tambo yekuvharisa ichakuvadzwa, iyo inogona kupedzisira yakonzera pfupi pfupi yedunhu kukanganisa.Tembiricha mamiriro eiyo insulation layer yetambo pasi peyakajairika ikozvino, yakawandisa ikozvino, uye pfupi yedunhu ikozvino.
Nokudaro, muhuwandu hwehuwandu hwechigadzirwa chemagetsi, muchengeti wedunhu anodiwa kuti ave 1.13In, iyo yakawandisa ikozvino haishande mukati meawa 1 (In≤63A}), uye kana ikozvino yakavhurwa pa 1.45In, iyo yakawandisa. mutsara unofanirwa kubviswa mukati meawa 1.Yakawandisa ikozvino inotenderwa kuenderera kweawa imwe yekufunga kuenderera kweiyo magetsi uye tambo pachayo ine imwe yakawandisa yekuremerwa, haigone kuve yakawandisa mutsara, wedunhu breaker ichacheka simba, izvo zvinokanganisa zvakajairika. kugadzirwa uye hupenyu hwevagari.
Chinhu chekudzivirira chedunhu rinoputika itambo.Pasi pemamiriro ekuremerwa, kuremerwa kwenguva refu kuchaita kuti tembiricha ikwire, zvichikonzera kukuvadzwa kweiyo insulation layer yetambo, uye pakupedzisira kukanganisa kupfupi kwedunhu.
Pasi pemamiriro edunhu mapfupi, tembiricha inokwira munguva pfupi kwazvo, kana isina kuchekwa nenguva, inogona kukonzera kupisa kwega kwegadzi rekudzivirira, kuitira sechikamu chekudzivirira chemugero wedunhu, zvese zviri zviviri kudzivirira basa, asi zvinodawo pfupi. basa rekudzivirira redunhu.
