Ukukhethwa kokutshintshwa kokukhusela ukuvuza kwibhokisi enye yenqanaba, ibhokisi leenqanaba ezimbini kunye nebhokisi lokuhambisa amanqanaba amathathu

Iiswitshi ziqhelekile kuthi njengabasebenzi bombane.Kodwa ngaba ngenene usebenzisa iiswitshi ezifanelekileyo kunye neenketho?

Tn-s nguyeukunikezwa Amandlaindlela yolwakhiwo lwesiza.Kukho amanqanaba amathathu okusasazwa kwamandla kunye namanqanaba amabini okukhusela.Kufuneka umatshini omnye, isango elinye, ukuvuza kunye nebhokisi enye.Umgca we-PE awuvunyelwe ukufaka iitshintshi, akuvumelekanga ukudibanisa izixhobo ezininzi zombane ngaphezu kokutshintsha.Kwaye isithuba phakathi kwebhokisi yokuqala, ibhokisi yesibini kunye nebhokisi yenqanaba lesithathu ziimitha ezingama-30.

Xa sikhetha ukutshintshela kwikhabhinethi yokusasazwa kwamanqanaba amathathu, kufuneka sinikele ingqalelo kwingxaki enjalo, oko kukuthi, ekusekweni kokhuseleko lokuvuza olulinganisiweyo lwangoku kunye nexesha lokuvuza elilinganisiweyo kufuneka libe nengqiqo, phepha isenzeko sokutsiba.

Ngokwesiqhelo xa sifaka unikezelo lwemfundo ephakamileyo ekukhetheni ezithathu kukuseta iukuvuza umkhuselikwibhokisi yokuhambisa, unikezelo lulonke lokulinganisa ukuvuza kwesenzo somkhuseli wokuvuza ukulinganisa ukuvuza okwangoku kungaphantsi okanye kuyalingana ne-150 ma ixesha lesenzo alikho ngaphezu kwemizuzwana eyi-0.2, inyathelo lesibini lokuvuza langoku alikho ngaphezu kwe-75 ma, lilinganiselwe. ixesha lesenzo sokuvuza alikho ngaphezu kwemizuzwana ye-0.1, Ukuvuza okusebenzayo okwangoku kwibhokisi yokutshintsha akuyi kudlula i-30 ma, kwaye ixesha lokusebenza elilinganisiweyo aliyi kudlula imizuzwana ye-0.1.Kwiindawo ezinomswakama, isenzo sokuvuza sangoku kwiindawo eziqhuba kakuhle azikho ngaphezu kwe-15 ma, kwaye ixesha alikho ngaphezu kwe-0.1 imizuzwana.

Xa sijongana neengxaki kutheni kufuneka sinyanzelise ukusetyenziswa kwee-circuit breakers ezicacileyo kunye nokuvuza kweesekethe zokuvuza.Kamva, ndabonisana nolwazi olufanelekileyo kwaye ndafunda ukuba kufuneka sishiye iindawo ezicacileyo zokuqhawula kumgca xa sifumana umbane kwindawo yesiganeko, ukuze siphephe imeko yokuba umgca awuqhawulwa ekusebenzeni okuphilayo.Ukusebenzisa ii-breakers zesekethe ezicacileyo kunye nabakhuseli bokuvuza banokujonga nge-intuitively ukuba umgca okanye iswitshi inqanyuliwe, ukuze uthintele umngcipheko wokutshatyalaliswa kombane.

Kukwakho ukusetyenziswa kwe-aI-3P i-circuit breakerkutheni nakwisiphelo sayo esisezantsi ukufaka i-3P+Nukuvuza kwesekethe umaphuli.Indima ye-circuit breaker kufuneka ivule kwaye ikhuphe kwaye ilayishe, ukhuseleko olufutshane lwesekethe.I-Leakage circuit breaker inomsebenzi wokukhusela ukuvuza ukongeza kwi-overload short circuit on and off.Ngenxa yodaka kunye namanzi amaninzi kwisiza, indawo yokwakha inzima kwaye ukufakwa komkhuseli wokuvuza kuye kwaba yinto ebalulekileyo yokhuseleko.
