Kwi-high-voltage vacuum vacuum breakers ezihlala zilungiswa rhoqo, kukho le miba ilandelayo:
Ezo kufuneka zihlaziywe qho ngeenyanga ezintandathu zezi:
1) Khangela imbonakalo yendlela yokuhambisa i-high-voltage vacuum circuit breaker, ucoce uthuli, kwaye usebenzise igrisi; qinisa i-fasteners ekhululekile; khangela indlela yokuhambisa ukuqinisekisa ukuvulwa okuthembekileyo kunye nokuvalwa kwe-breaker circuit; coca i-breaker circuit, Yenze icoceke ukuqinisekisa ukusebenza okukhuselekileyo; sebenzisa igrisi yokuthambisa ukwenza isixhobo sibhetyebhetye kwaye sinciphise ukukhuhlana kunye nokuguga.
2) Khangela ukuba i-core yentsimbi ye-coil yokuvala ibambekile, ingaba amandla okuvala ahlangabezana neemfuno, kunye neziko elifileyo lokubamba (indawo enkulu kakhulu efileyo iya kubangela ubunzima ekuvuleni, kwaye ukuba incinci kakhulu, iya kuba yinto enzima kakhulu." ukuwa ngokulula).
3) Imeko yePin: Nokuba iphini elimile okweshiti libhityile kakhulu; nokuba isikhonkwane esimilise okwekholamu sigobile okanye sinokuwa.
4) Isithinteli: Ingaba i-hydraulic buffer ivuza ioli, inomlinganiselo omncinci weoli okanye ayisebenzi; ingaba isithinteli sasentwasahlobo siyasebenza.
5) Ingaba i-core tripping ingahamba ngokukhululekileyo.
6) Ingaba kukho iziphene ezibonakalayo kumacandelo e-insulation. Ukuba kukho naziphi na iziphene, sebenzisa i-2500V shake meter ukuvavanya ukugquma ukuze ubone ukuba utshintshe kwaye wenze irekhodi.
I-7) Sebenzisa ibhuloho yengalo ephindwe kabini ukulinganisa ukuchasana kwe-DC yokutshintsha emva kokuvalwa (akumele kube mkhulu kune-40Ω), kwaye wenze irekhodi, ukuba ikhulu kune-Ω, igumbi lokucima i-arc kufuneka litshintshwe.
8) Khangela ukuba igumbi lokucima i-arc liphukile, kwaye ingaba iindawo zangaphakathi ziyaguga.
9) Khangela isiphaluka sesibini kwaye ulinganise ukuchasana kwe-insulation yesekethe yesibini.
Ezo kufuneka ziqwalaselwe ngokutsha ngonyaka zezi:
1) Ixesha lokuvala: i-DC electromagnetic ayikho ngaphezu kwe-0.15s, ukugcinwa kwamandla entwasahlobo akukho ngaphezu kwe-0.15s; ixesha lokuvula alikho ngaphezu kwe-0.06s; i-synchronism yezivulo ezintathu zingaphantsi okanye zilingana no-2ms;
2) Ixesha le-bounce lokuvala uqhagamshelwano ≤5ms;
3) Umyinge wokuvala isantya ngu-0.55m/s±0.15m/s;
4) I-avareji yesantya sokuvula (phambi kokuqhagamshelana ne-oyile buffer) 1m/s±0.3m/sc
Ukulinganisa inqanaba lokugquma elilinganisiweyo, ngokuqhelekileyo umlinganiselo wamandla e-lmin wokumelana nombane wama-42kV, akukho flashover; ngokungenamiqathango, umlinganiselo weqondo le-vacuum unokushiywa, kodwa i-frequency yamandla yokumelana novavanyo lwe-voltage phakathi kwezigaba kunye noqhekeko kufuneka lwenziwe, kwaye i-42kV okanye ngaphezulu iyafuneka (akukho miqathango yamandla ombane Inokutshintshwa yi-DC). Kwizaphuli zesekethe ezisetyenziselwe iminyaka emi-5 ukuya kweli-10, umenzi kufuneka alungelelanise umgama wokuvula unxibelelwano, ukubetha koqhagamshelwano, i-oyile buffer buffer stroke, umgama ophakathi kwesigaba, ungqamaniso lokuvula amanqanaba amathathu, ukuvala uxinzelelo lokunxibelelana, ixesha lokutsiba, ukongezeleka. Ubukhulu obuvumelekileyo bokunxiba bonxibelelwano oluhambayo kunye noluzinzileyo, njl.
