Isilinda sokukhusela izixhobo ze-VI kunye nezixhobo zamandla aphezulu
Ingcaciso yeMveliso
Njenge "arc barrier" esembindini we-vacuum interruptors, ii-shield cylinders zethu zenziwe ngesakhiwo esiyinkimbinkimbi esidibeneyo, sidibanisa ubhedu olungena-oxygen ecocekileyo kakhulu kunye nentsimbi engagqwaliyo yodidi olukhethekileyo. Olu dibaniso lwezinto aluyongozi: ubhedu olungena-oxygen ecocekileyo kakhulu luzisa amandla okuqhuba umbane abalaseleyo kunye nokukwazi ukufunxa ubushushu, ngelixa intsimbi engagqwaliyo ekhethekileyo inegalelo ekuchaseni okuphezulu kokukhukuliseka kwe-arc kunye nokuqina koomatshini, ukuqinisekisa ukuba isilinda yesihlangu inokumelana neemeko ezinzima zokusebenza kwe-high-voltage.
Ukuze sifezekise ukuchaneka okufunekayo kwinxalenye ebaluleke kangaka, sisebenzisa iinkqubo zokuvelisa eziphambili: ukuzoba ngokuchanekileyo kuqala kubumba isinyithi sibe yimo ye-cylindrical efunekayo, kuqinisekisa ukuthembeka kwesakhiwo kunye nobukhulu bodonga obufanayo, ngelixa ukugaywa kwe-CNC okulandelayo kuphucula umphezulu wangaphakathi ube sekupheleni okufana nesipili kunye noburhabaxa be-Ra0.4 okanye ngaphantsi. Olu nyango lucokisekileyo lomphezulu lungaphezulu kakhulu kuneenkcukacha zobuhle—ludlala indima ebalulekileyo ekusebenzeni kwenxalenye.
Udonga lwangaphakathi oluthambileyo kakhulu lufunxa ngokufanelekileyo amandla e-arc, luthintela ukwakheka kobushushu obugqithisileyo obunokonakalisa izinto ezingqongileyo. Lukwanceda ukwenza usasazo lwentsimi yombane ngaphakathi kwe-vacuum interrupter lufane, lunciphise umngcipheko wokuqina kwentsimi okunokukhokelela ekuqhekekeni kwe-insulation. Ngaphezu koko, lo mphezulu usemgangathweni ophezulu unciphisa ukunamathela komphunga wesinyithi owenziwe ngexesha lokuphazamiseka kwe-arc, nto leyo egcina ukusebenza kwe-insulation ye-interrupter ngokuhamba kwexesha. Zidibene, ezi mpawu azigcini nje ngokuphucula amandla e-vacuum interrupter okuphazamisa ngokukhuselekileyo nangokuthembekileyo umbane kodwa zandisa nobomi bayo benkonzo iyonke, okwenza ii-shield cylinders zethu zibe yinxalenye ebalulekileyo yeenkqubo zamandla aphezulu.
Ukuphendula kwiimfuno zezixhobo zamanqanaba ahlukeneyo e-voltage (12kV-550kV), singenza ngokwezifiso isakhiwo esidibeneyo ukusuka emzimbeni wesilinda ukuya kwi-flange. Ngokulungisa ubukhulu bodonga kunye noyilo lwe-diversion groove, siqinisekisa ukuqina okuzinzileyo kwe-vacuum (izinga lokuvuza ≤1×10⁻⁹Pa・m³/s) ngexesha lemijikelo yokutshintsha eyi-100,000. Sisebenzisa amava ethu okuvelisa afanayo kunye nezinto eziphambili ezifana nee-bellows, ukunyamezelana kwendibano phakathi kwesilinda yesihlangu kunye nabafowunelwa, kunye neentonga zokutsala ezifakelwayo, kulawulwa ngokungqongqo ngaphakathi kwe-±0.02mm, kulungelelaniswa ngokugqibeleleyo neemeko zokusebenza kwezixhobo zizonke. Ukusuka ekuhlolweni kwe-spectral kwezinto eziluhlaza ukuya ekufumaneni ukuvuza kwe-helium mass spectrometry yeemveliso ezigqityiweyo, inkqubo yolawulo lomgangatho wenkqubo epheleleyo iqinisekisa ukuba yonke imveliso inokumelana novavanyo olunzima lwe-voltage ephezulu kunye nee-arcs ezinamandla, ibonelela ngenkxaso yokukhusela ethembekileyo kwiiprojekthi ezifana neegridi ezikrelekrele kunye nokudluliselwa kwe-voltage ephezulu kakhulu.
