Ukusebenza kwegumbi lokucima i-arc yokucima i-vacuum inquma ukusebenza kwe-contactor, kunye neempawu zomatshini ze-contactor ngokwayo nazo zigqiba ukusebenza kwegumbi lokucima i-arc. yegumbi lokucima i-vacuum arc elihambelanayo.
Okokuqala, ukujonga kuqala kwi-contact pressure.Xa i-vacuum arc yokucima i-arc isebenza ngaphandle kwamandla angaphandle, uqhagamshelwano oluguquguqukayo luvale kunye noqhagamshelwano olusisigxina phantsi kwesenzo soxinzelelo lwe-atmospheric, olubizwa ngokuba yi-autistic force.Ubungakanani bamandla buxhomekeke kwizibuko indawo enqamlezileyo yemvulo.Ngokuqhelekileyo, amandla okuvala akakwazi ukuqinisekisa uqhagamshelwano olufanelekileyo lombane phakathi koqhagamshelwano oluguquguqukayo kunye ne-static lwegumbi lokucima i-arc ye-vacuum, kunye noxinzelelo lwangaphandle lubekwe phezulu.Ubukhulu bolu xinzelelo buxhomekeke kwizinto ezintathu: a.Ireyithingi yangoku yegumbi le-arc;b.Izinto zoqhagamshelwano zegumbi le-arc;c.Ukunyanzeliswa kombane phakathi koqhagamshelwano oluguquguqukayo kunye ne-static xa igumbi le-arc livaliwe.Ngokwezi zinto ukukhetha uxinzelelo olusetyenzisiweyo olufanelekileyo, amandla okuvalwa kunye noxinzelelo lwangaphandle oluphezulu lubizwa ngokuba yingcinezelo yoqhagamshelwano yentloko yoqhagamshelwano, ebizwa ngokuba yi-terminal pressure.
2. Indima yoxinzelelo lwe-terminal kwi-contactor.Uxinzelelo lwe-terminal olunengqiqo, Qinisekisa ukuchasana koqhagamshelwano olufanelekileyo phakathi koqhagamshelwano oluguquguqukayo kunye ne-static yegumbi lokucima i-arc, Ukuchasana koqhagamshelwano kunokulinganiswa ngumxhasi wesiphaluka;Uxinzelelo olufanelekileyo lwesiphelo, Iyakwazi ukuhlangabezana neemfuno zokuzinza kobushushu obuguquguqukayo begumbi lokucima i-arc ye-vacuum, Inokoyisa ukunyanzeliswa phakathi kwabafowunelwa kwindawo ephezulu yangoku, Ukuqinisekisa ukuvalwa ngokupheleleyo ngaphandle komonakalo, oko kukuthi, abafowunelwa abayi kunamathela ukufa;Uxinzelelo lwe-terminal olufanelekileyo, lunokunciphisa ukucuthwa, amandla empembelelo abangela uqhagamshelwano xa luvaliwe, lufunxwa ngamandla anokubakho;Uxinzelelo lwe-terminal olufanelekileyo, Ukulungele ukutshintsha iimpawu, Xa uxinzelelo lwe-terminal luhlangabezana neemfuno, Ukunyanzeliswa kwentwasahlobo yoqhagamshelwano nayo inkulu, Amandla anamandla e-elastic nawo makhulu, Ukunyusa isantya sokuqala sesango lokutshintsha, Ukunciphisa ixesha le-arc elivuthayo kunye ukuphucula umthamo wokutshintsha.
Isithathu, inkcazo kunye nomsebenzi we-overtravel.Nayiphi na i-vacuum switch ivaliwe kwimodi yokugqithisa, xa ivaliwe, abafowunelwa abanamandla abakwazi ukuqhubela phambili emva kokuqhagamshelana nabafowunelwa be-static, kodwa uxinzelelo phakathi koqhagamshelwano oluguqukayo ludinga. intwasahlobo.Xa ukunyakaza kunye nokunyakaza kungqubana, amandla kwi-spring yoqhagamshelwano aya kuqhubeka ehamba.Umgama wokufuduka ngexesha lokunyakaza kukunyanzeliswa kwe-spring ye-contact, eyi-overstroke.Ukongezelela ekunyuseni isantya sokuqala sokutshintsha, ukugqithisa kunemisebenzi emibini ebalulekileyo: a.Amandla entwasahlobo yoqhagamshelwano adluliselwa kuxinzelelo loqhagamshelwano phakathi kwabafowunelwa ukuhlangabezana neemfuno zokusebenza;b.Emva kokusebenza kwexesha elide loqhagamshelwano, abafowunelwa baya kutshisa kwaye banciphise ubukhulu boqhagamshelwano.Ukuba i-overstroke enengqiqo iqinisekisiwe, uxinzelelo oluthile lwe-terminal lunokwenza abafowunelwa be-vacuum basebenze ngokuqhelekileyo. Enyanisweni, i-spring pressure yoqhagamshelwano inike ukunyanzeliswa kwe-contactor switch state, okukuvala umzuzu woqhagamshelwano, ukufikelela kwixabiso loxinzelelo lwangaphambi kokunciphisa i-bounce yokuvala, xa ukunyakaza kwe-overstroke iphela, uxinzelelo lwe-terminal lukwahlangabezana neemfuno zoyilo.
Isine, inkcazo yexesha lokuvala kunye nexesha lokuvala kunye nefuthe lobude bexesha ekusebenzeni kokutshintsha.
