Ukuqonda Umahluko phakathi kweSwitshi yokuBeka yodwa kunye neFuse yokwahlula iSwitch

1. Isakhiwo

1. Umtshini wokuzihlukanisa unesakhiwo esilula kwaye uqukethe umatshini wokutshintsha kunye noqhagamshelwano. Umsebenzi wayo oyintloko kukunqumla okanye ukudibanisa isiphaluka kwaye ineempawu ezintle zomatshini kunye nombane. Umtshini wokwahlula wohlobo lwe-fuse kufuneka ube namacandelo amathathu: i-fuse, iswitshi yokwahlula kunye nesekethe yamandla. Isekethe yamandla idinga i-fuse kunye nokutshintsha okukodwa ukuba kudityaniswe ukuze kukhuselwe izixhobo zombane kwiimeko ezingaqhelekanga zokusebenza ezifana nomthwalo ongaphezulu, ukulayisha ngaphantsi okanye isekethe emfutshane.

2. Umtshintshi wokwahlula ngokuqhelekileyo wamkela isakhiwo se-indexing kwaye uneendlela eziguquguqukayo kunye neendlela ezahlukeneyo zokufakela. Ulungelelwaniso olusekelwe kunye nolungenasiseko lunokukhethwa ngokweemfuno zokwenyani. I-fuse-type-isolation switch is more component-based, kwaye i-fuse inokudityaniswa ngokuhambelana nomlinganiselo wangoku wesixhobo sombane ukuze kuqinisekiswe amandla okutshintsha umthwalo wendalo yokutshintsha okukodwa kunye nokukwazi ukumelana nombane ophezulu kunye ne-short-circuit.

2. Umsebenzi

1. Umsebenzi oyintloko wokutshintshwa kwe-isolation kukwenza ulawulo lokucima kunye nokudlala indima yodwa ngexesha lokugcinwa nokulungiswa kwezixhobo zombane. Isitshixo sokwahlula kufuneka sisetyenziselwe ukubekwa wedwa xa usebenzisa isixhobo sombane esine-high-voltage. I-fuse-type-isolation switch nayo inomsebenzi wokukhusela i-fuse, enokukhusela isiphaluka sokufikelela ekugqithiseni kunye nokugqithisa.

2. Ukutshintsha okukodwa ngokuqhelekileyo kusetyenziswa kwiinethiwekhi zendandatho eziphantsi-voltage, ezisondele kunikezelo lwamandla, kwaye ukuvala ukutshintshwa kwe-isolation kufuna umsebenzi omncinci womthwalo; ngelixa i-fuse-uhlobo lwe-slove switches idla ngokusetyenziswa kuthungelwano lwe-ring-voltage ephezulu, kwaye imisebenzi yabo yokugcina iyinkimbinkimbi kwaye ifuna Kwisiseko sokuhlangana nomsebenzi wokutshintsha umthwalo, nayo inomsebenzi wokukhusela ukuya kumlinganiselo omkhulu, kunye neemfuno zokuguquguquka kombane, inqanaba lokugquma kunye nokhuseleko lomntu nazo ziphezulu kakhulu.

3. Sebenzisa

1. Ukutshintsha okukodwa ngokuqhelekileyo kusetyenziselwa ukwahlula amandla, ukutshintshwa kokulawula, kunye nokusika izixhobo zombane kwimisebenzi yokugcinwa kwesibini. Izitshixo zokwahlula zohlobo lwe-Fuse zidla ngokusetyenziswa kwizixhobo eziphezulu ze-voltage ezifana neekhabhathi zokutshintsha kwe-voltage ephezulu, iinkqubo ezizisebenzelayo zokusasaza, iijeneretha, kunye neziguquli.

2. Ngokwemigaqo yokusetyenziswa, izinto zokuphakamisa umtshini wokuzihlukanisa zilula. Ufuna kuphela ukuhlangabezana nemigangatho kwaye ukhethe imilinganiselo ehambelanayo; ngelixa iswitshi yokwahlula yohlobo lwe-fuse inomda wobugcisa obuphezulu kwaye ifuna izakhono ezithile zobugcisa ukuthenga, ukusebenzisa, kunye noLondolozo kunye neminye imisebenzi.

Ukutshintsha okukodwa kunye nohlobo lwe-fuse-uhlobo lokuzihlukanisa lufana nomsebenzi wokuzihlukanisa, kodwa kukho umahluko omkhulu kwisakhiwo, umsebenzi kunye nokusetyenziswa. Ukukhetha iswitshi ethile yokwahlula ifuna uqwalaselo olubanzi lwemiba efana namathuba okusetyenziswa, iimfuno zezixhobo, kunye neendleko zemveliso.
