Kuma-air-voltage vacuum circuit breaker ahlala elungiswa kabusha, kunezici ezilandelayo:
Okudinga ukulungiswa njalo ezinyangeni eziyisithupha yilezi:
1) Hlola ukubukeka kwendlela yokudlulisa ye-high-voltage vacuum circuit breaker, hlanza uthuli, futhi usebenzise amafutha; qinisa ama-fasteners avulekile; hlola indlela yokudlulisa ukuze uqinisekise ukuvulwa nokuvalwa okuthembekile kwe-breaker circuit; hlanza i-breaker circuit, Yenza ihlanzeke ukuze uqinisekise ukusebenza okuphephile; sebenzisa amafutha okugcoba ukuze wenze umshini uvumelane nezimo futhi unciphise ukungqubuzana nokuguga.
2) Hlola ukuthi umgogodla wensimbi wekhoyili yokuvala ubhajwe yini, ukuthi amandla okuvala ayahlangabezana yini nezidingo, futhi indawo efile yokubamba (indawo efile enkulu kakhulu izodala ubunzima ekuvuleni, futhi uma incane kakhulu, izokwenza aphume kalula).
3) Isimo sephini: Ukuthi iphinikhodi emise okweshidi izacile kakhulu; noma ngabe iphinikhodi emise okwekholomu igobile noma ingase iwe.
4) Isigcinalwazi: Ukuthi ingabe isivali se-hydraulic siwuwoyela ovuzayo, sinowoyela omncane noma asisebenzi; noma ngabe i-spring buffer iyasebenza.
5) Ukuthi umgogodla wokukhubeka ungahamba ngokukhululeka.
I-6) Ukuthi kukhona ukukhubazeka okubonakalayo ezingxenyeni zokufakelwa. Uma kukhona noma yikuphi ukukhubazeka, sebenzisa imitha yokunyakazisa engu-2500V ukuze uhlole okokufaka ukuze unqume ukuthi uzoshintsha futhi wenze irekhodi.
7) Sebenzisa ibhuloho elinezingalo ezimbili ukukala ukumelana kwe-DC kweswishi ngemva kokuvalwa (akufanele kube kukhulu kuno-40Ω), futhi wenze irekhodi, uma likhulu kuno-Ω, igumbi lokucima i-arc kufanele lishintshwe.
8) Hlola ukuthi igumbi lokucisha i-arc liphukile, nokuthi izingxenye zangaphakathi ziyaguga.
9) Hlola isifunda sesibili futhi ulinganise ukumelana nokufakwa kwesifunda sesibili.
Okumele kulungiswe kabusha ngonyaka yilezi:
I-1) Isikhathi sokuvala: I-DC electromagnetic ayikho ngaphezu kwe-0.15s, isitoreji samandla entwasahlobo asikho ngaphezu kwama-0.15s; isikhathi sokuvula asikho ngaphezu kuka-0.06s; i-synchronism yezikhala ezintathu ingaphansi noma ilingana no-2ms;
2) Isikhathi sokugxuma sokuvala othintana naye ≤5ms;
3) Isivinini sokuvala esimaphakathi ngu-0.55m/s±0.15m/s;
4) Isivinini sokuvula esimaphakathi (ngaphambi kokuthi uthinte isigcinalwazi sikawoyela) 1m/s±0.3m/sc
Ukuze ulinganise izinga lokuhlukanisa elilinganiselwe, ngokuvamile kala kuphela imvamisa yamandla e-lmin ukumelana ne-voltage engu-42kV, akukho flashover; ngaphandle kwemibandela, isilinganiso sedigri ye-vacuum singashiywa, kodwa imvamisa yamandla imelana nokuhlolwa kwe-voltage phakathi kwezigaba nokuphuka kufanele kwenziwe, futhi i-42kV noma ngaphezulu iyadingeka (azikho izimo zefrikhwensi yamandla Engashintshwa yi-DC). Kuma-breaker circuit vacuum asetshenziswe iminyaka engu-5-10, umenzi kufanele alungise ibanga lokuvula othintana naye, i-stroke yokuxhumana, i-buffer buffer stroke, ibanga lesikhungo sesigaba, ukuvumelanisa okuvula izigaba ezintathu, ukuvala ingcindezi yokuxhumana, isikhathi sokugxuma, I-cumulative. Ubukhulu obuvumelekile bokugqoka othintana nabo abahambayo nabamile, njll.
