Ukuqonda Umahluko Phakathi Kokutshintsha Okwahlukileyo kunye Nokutshintsha Okwahlukileyo Kwefuse

1. Ulwakhiwo

1. Iswitshi yokwahlukanisa inesakhiwo esilula kwaye inendlela yokutshintsha kunye noqhagamshelwano. Umsebenzi wayo ophambili kukusika okanye ukudibanisa isekethe kwaye ineempawu ezilungileyo zoomatshini nezombane. Iswitshi yokwahlukanisa uhlobo lwefuse kufuneka ibe namacandelo amathathu: ifuse, iswitshi yokwahlukanisa kunye nesekethe yamandla. Isekethe yamandla ifuna ukuba ifuse kunye neswitshi yokwahlukanisa ziqhagamshelwe ukukhusela izixhobo zombane kwiimeko zokusebenza ezingaqhelekanga ezifana nokugqithiswa kakhulu, umthwalo ongaphantsi okanye isekethe emfutshane.

2. Iswitshi yokuzihlukanisa idla ngokusebenzisa isakhiwo sokukhomba kwaye ineendlela zokufakela eziguquguqukayo nezihlukeneyo. Uqwalaselo olusekelwe emhlabeni nolungenamhlaba lunokukhethwa ngokweemfuno zokwenyani. Iswitshi yokuzihlukanisa yohlobo lwefuse isekelwe ngakumbi kwinxalenye, kwaye ifuse inokufaniswa ngokwesantya esilinganisiweyo sezixhobo zombane ukuqinisekisa amandla okutshintsha umthwalo weswitshi yokuzihlukanisa kunye nokukwazi kwayo ukumelana nombane ophezulu kunye ne-short-circuit ephezulu.

2. Umsebenzi

1. Umsebenzi ophambili weswitshi yokwahlukanisa kukulawula ukucima kwaye udlale indima yokwahlukanisa ngexesha lokugcinwa nokulungiswa kwezixhobo zombane. Iswitshi yokwahlukanisa kufuneka isetyenziswe ekuhlukaniseni xa kusetyenziswa izixhobo zesikhululo esinombane ophezulu. Iswitshi yokwahlukanisa uhlobo lwefuse ikwanomsebenzi wokukhusela ifuse, onokukhusela isekethe yokufikelela ekutshiseni kakhulu nasekugqithiseni kakhulu.

2. Iiswitshi zokuzihlukanisa zihlala zisetyenziswa kwiinethiwekhi zeringi ezine-voltage ephantsi, ezikufutshane nombane, kwaye ukuvala iswitshi yokuzihlukanisa kufuna umsebenzi omncinci womthwalo; ngelixa iiswitshi zokuzihlukanisa ze-fuse-type zihlala zisetyenziswa kwiinethiwekhi zeringi ezine-voltage ephezulu, kwaye imisebenzi yazo yokulungisa iyinkimbinkimbi kwaye ifuna. Ngenxa yokuhlangabezana nomsebenzi wokutshintsha umthwalo, ikwanawo nomsebenzi wokukhusela kakhulu, kwaye iimfuno zokuzivumelanisa nombane, inqanaba lobushushu kunye nokhuseleko lomntu nazo ziphezulu.

3. Sebenzisa

1. Iiswitshi zokwahlukanisa zihlala zisetyenziswa ekuhlukaniseni umbane, kwiiswitshi zokulawula, nasekunqumleni izixhobo zombane kwimisebenzi yolondolozo lwesibini. Iiswitshi zokwahlukanisa uhlobo lwefuse zihlala zisetyenziswa kwizixhobo ze-voltage ephezulu ezifana neekhabhathi zeswitshi ze-voltage ephezulu, iinkqubo ze-othomathikhi zokusasazwa, iijenereyitha, kunye neetransformer.

2. Ngokuphathelele ukusetyenziswa, izinto zokuphakamisa zeswitshi yokwahlukanisa zilula kakhulu. Udinga kuphela ukuhlangabezana nemigangatho kwaye ukhethe iinkcukacha ezifanelekileyo; ngelixa iswitshi yokwahlukanisa uhlobo lwefuse inomlinganiselo ophezulu wobugcisa kwaye ifuna amandla athile obuchwephesha ukuze uthenge, usebenzise, ​​kwaye ulungise neminye imisebenzi.

Iiswitshi zokuzihlukanisa kunye neeswitshi zokuzihlukanisa ze-fuse-type ziyafana kumsebenzi wokuzihlukanisa, kodwa kukho umahluko omkhulu kwisakhiwo, umsebenzi kunye nokusetyenziswa. Ukukhethwa kweswitshi yokuzihlukanisa ethile kufuna ukuqwalaselwa ngokubanzi kwezinto ezifana neziganeko zokusetyenziswa, iimfuno zezixhobo, kunye neendleko zemveliso.
