ISWITSHI YOMTHWALO WEKHOLAM YE-10KV

Iswitshi yokulayisha kwikholam inamandla okuthwala nokuphula umsinga olinganisiweyo, kodwa ayinakuphula umsinga we-short-circuit. Isetyenziswa kakhulu ekuhlukaniseni umgca kunye nokwahlukanisa iimpazamo.

(1) Iswitshi yomthwalo evelisa igesi. Iswitshi yomthwalo evelisa igesi isebenzisa umngxuma owenziwe zizinto eziqinileyo ezivelisa igesi ukuvelisa inani elikhulu legesi phantsi kwesenzo se-arc ukwenza i-arc evuthela igesi. Ngenxa yesakhiwo sayo esilula kunye nexabiso eliphantsi, yayisasetyenziswa kakhulu.

(2) Iswitshi yokuvula i-vacuum, i-SF6 load switch. Ifana ngembonakalo kunye neeparamitha ze-vacuum kunye ne-SF6 circuit breakers, umahluko kukuba iswitshi yokuvula ayinazo izixhobo zokukhusela i-CT kwaye ayinakuphula i-short-circuit current, kodwa inokumelana ne-short-circuit current kunye ne-short-circuit current, enobomi obude, iimpawu ezingenalondolozo, ubomi boomatshini, i-rated current current ivuliwe. Inani lokuphazamiseka lingaphezulu kwe-10,000 amaxesha, elifanelekileyo kwimisebenzi eqhubekayo.

(3) Iingcebiso zokusetyenziswa:

①Ngokwembono yokusetyenziswa, izinga lokungaphumeleli kweswitshi yomthwalo evelisa igesi liphezulu, isigqubuthelo sokucima i-arc siwile, kwaye iswitshi enepali enye itshiswe amaxesha amaninzi. Ukuqhekeka kwe-carbonized ye-epoxy resin insulators.

②Xa iswitshi ivuliwe, iswitshi yomthwalo evelisa igesi ngamanye amaxesha iya kuvelisa ukuvuza kokukhanya kwe-arc, nto leyo echaphazela ukhuseleko lomntu. Ngokwentshayelelo yomenzi, inkqubo yokucima i-arc yoyilo lweswitshi iqwalasela ikakhulu umthwalo ongaphantsi komthwalo ophilayo. Xa oonxibelelwano abaphambili nabancedisayo bengavumelani, kulula ukuba i-Arc ivuleke ngokukhawuleza.

③Isigqubuthelo sokucima i-arc sesitshixo somthwalo esivelisa igesi kufuneka sigcinwe ngendlela engaqhelekanga. Sifanele sihlolwe kwaye sigcinwe malunga namaxesha angama-20 emva kokuphula umthwalo opheleleyo. Asilunganga njengeswitshi yohlobo lwe-vacuum kunye ne-SF6, enokwaphulwa ngaphezu kwamaxesha ali-10,000, kwaye umthwalo wokusebenza nokugcinwa kwexesha elide mkhulu.

④Indlela yokusebenza yeswitshi yomthwalo evelisa igesi inokwahlulwa ibe luhlobo lwehoko kunye nohlobo lwe-pull-down operation lever. Uhlobo lwe-pull-down operation lever kufuneka lutshixwe xa kufakwa isiphatho sokusebenza, kwaye umzimba wokutshixa kufuneka utshintshwe kwaye ugcinwe ngamanye amaxesha, nto leyo engathandekiyo ukuyisebenzisa. Intonga yokusebenza kufuneka ifakwe ngaphezulu kwe-2.5M ngaphezu komhlaba, kungenjalo iya konakala lula ngamandla angaphandle.

⑤Ixabiso langoku leswitshi yokudibanisa umthwalo we-vacuum liyafana neleswitshi evelisa igesi, kwaye ukuthembeka kwayo kunye nokhuseleko azinakuthelekiswa neswitshi evelisa umthwalo wegesi, ngoko ke kufuneka isetyenziswe xa ukhetha.
