Inxalenye ebalulekileyo edlala indima ebalulekileyo ekukhuseleni ezi nkqubo yii-vacuum circuit breaker . Ngeepropathi eziphezulu zokucima i-arc kunye ne-insulating,vacuum zesekethe breakers baye baguqula ukhuseleko nolawulo lwezixhobo zombane. Kule bhlog, siza kuphonononga kwiimpawu kunye nokusetyenziswa kwevacuum zesekethe breakers, etyhila isizathu sokuba zisetyenziswe ngokubanzi kwiinkalo ezahlukeneyo zemizi-mveliso.
1. Qonda ii-vacuum circuit breaker:
Vacuum zesekethe breakers sebenzisa i-vacuum ephezulu njenge-arc yokucima kunye ne-insulating medium kwi-gap yoqhagamshelwano. Ngokungafaniyo nabaphuli beesekethe bendabuko abaxhomekeke kwioli okanye kwigesi, esi sisombululo sanamhlanje sibonelela ngeenzuzo ezininzi. Ubungakanani bayo obuncinci kunye nobunzima obulula bukwenza kube lukhetho olusebenzayo kwiindawo ezinendawo encinci. Ukongeza, i-vacuum circuit breakers ilungele ukusebenza rhoqo kwaye ifuna ukulungiswa okuncinci kokucima i-arc. Ezi mpawu zikhethekileyo ziye zaqinisekisa ukuthandwa kwazo kwiinethiwekhi zokusasazwa kwehlabathi apho ukuthembeka nokusebenza kakuhle kubaluleke kakhulu.
2. Ukuguquguquka kwesicelo:
Izaphuli zesekethe zevacuum zizinto eziyimfuneko kwiinkqubo zokuhambisa amandla angaphakathi ezisebenza kwi-3-10kV, 50Hz iinkqubo ze-AC zesigaba sesithathu. Ukuguquguquka kwayo kuvumela ukuba isetyenziswe kwiimeko ezahlukeneyo ezifana namashishini kunye nemigodi, amashishini ombane, kunye nezitishi. Ukongeza, ibonakalise ukuba luncedo ngakumbi apho i-oyile ingenawo, ukugcinwa okuphantsi, kunye nokusebenza rhoqo kufuneka. Oku kulungelelanisa kwenza kube yinto efanelekileyo yokulawula kunye nokukhusela izixhobo zombane eziphezulu kwiindawo ezahlukeneyo.
3. Ulungelelwaniso ukuhlangabezana neemfuno ezahlukeneyo:
Ukuhlangabezana neemfuno ezahlukeneyo zokufakela, i-vacuum circuit breakers ifumaneka kwiindlela ezahlukeneyo zokucwangcisa. Ukhetho oludumileyo yikhabhinethi ephakathi, ehlala isetyenziselwa ukulawula nokukhusela izixhobo zombane. Iikhabhinethi ezinedekhi ezimbini zibonelela ngokulula okongezelelweyo kulawulo olusebenzayo lweenkqubo zokuhambisa amandla. Ukongezelela, iikhabhinethi ezisisigxina zibonelela ngesisombululo esithembekileyo nesikhuselekileyo sokulawula kunye nokukhuselwa kwezixhobo zombane eziphezulu. Olu lungelelwaniso lwahlukeneyo lubonelela abaqulunqi kunye neenjineli ngokuguquguquka, ukuqinisekisa ukuba i-vacuum circuit breakers inokudityaniswa ngokungenamthungo kulo naluphi na ufakelo lokuhambisa amandla.
4. Izibonelelo ezingaphaya koncedo:
Ukongezelela ekuboneleleni ngokulula kunye nokulungelelaniswa, ukubaluleka kwe-vacuum circuit breakers kwandisa ukusebenza kakuhle kunye nokhuseleko lweenkqubo zombane. Ngokucima ngokufanelekileyo i-arc, umngcipheko wokungaphumeleli kombane uyancitshiswa kwaye amandla afumaneka ngokuqhubekayo. Emva koko, oku kwandisa imveliso kwaye kuthintele ixesha lokuphumla kunye nomonakalo onokwenzeka kwizixhobo zombane. Ukongezelela, ukungabikho kweoli okanye igesi kuthetha ukuba i-vacuum circuit breakers ayifaki ingozi yokusingqongileyo, ibenza isisombululo esinobume bendalo sophuhliso oluzinzileyo.
Ukuqukumbela, i-vacuum circuit breakers ibonakalise amandla abo njengamacandelo athembekileyo, asebenzayo kunye ahlukeneyo kwiinkqubo zokuhambisa amandla. Ubungakanani babo obuncinci, ubunzima obulula kunye neendleko eziphantsi zokugcinwa zitshintshile indlela izixhobo zombane ezilawulwa ngayo kwaye zikhuselwe. Ngokubonelela ngesakhono esigqwesileyo sokucima i-arc kunye nokusebenza kwe-insulation, i-vacuum circuit breakers idlala indima ephambili ekuqinisekiseni ukubonelelwa kombane okungaphazamisekiyo kumacandelo ahlukeneyo oshishino. Ziyakwazi ukuguquguquka kuqwalaselo kwaye zinokudibaniswa ngokungenamthungo kwiiseto ezahlukeneyo, ukwenza
