Surgeumbambisisixhobo sokugquma esisetyenziselwa ukukhusela isixokelelwano kwi-overvoltage.I-Zinc oxide surge arrester luhlobo lwesixhobo sokukhusela i-overvoltage esiye sasetyenziswa ngokubanzi kwinkqubo yamandla.I-Zinc oxide arrester nge-porcelain okanye i-insulator yeglasi, i-valve, iibholithi ezisisigxina kunye nezinye izinto.Kwiminyaka yakutshanje, i-ZnO arrester isetyenziswa kakhulu kwinkqubo yamandla, enokukhusela inkqubo ekugqithiseni.
Ulwakhiwo
I-Zinc oxide arrester ngumkhono we-porcelain, i-valve, iibholithi ezisisigxina kunye nezinye izinto.Ubume obuphambili:
1. Izinto ze-ceramic insulator ziyiglasi, i-alumina kunye ne-zinc oxide, kunye ne-zinc oxide lightning arrester ehlanganiswe ne-ceramic insulator ine-insulator egqwesileyo yokusebenza, umthamo omncinci kunye nobunzima obulula, kwaye sisixhobo sokukhusela esisetyenziswa ngokubanzi kwinkqubo yamandla.
2. Idiskhi yeValve: equka enye okanye ngaphezulu iifilimu zetsimbi ezimile rhoqo, ezibandakanya i-zinc oxide, ifoyile yentsimbi okanye ifoyile yeglasi.Isibambi sombane singasetyenziselwa ukukhusela izixhobo zombane ekugqithiseni umbane kwinkqubo yamandla.
3. Iibholiti zokulungisa zisetyenziselwa ukudibanisa kunye nokuxhasa phakathi kweqhekeza levalve yokulungisa kunye nesihlalo se-valve.
Umgaqo wokusebenza
I-Zinc oxide lightning arrester yenziwe ngeqhekeza levalve, i-porcelain insulator (okanye i-glass insulator), i-bolt yokulungisa kunye nomkhono we-porcelain.Umbane we-impulse current ukhawulelwe yi-over-voltage absorbing element yesiqhekeza sevalve.Inkqubo yesiphumo yile ndlela ilandelayo: xa i-wave wave ihlasela, isibambisi sombane sithatha ngokukhawuleza amandla kwaye sivelise i-frequency yamandla amakhulu ngoku ngesiqwenga sevalve;ukuba igagasi lombane liyaqhubeka nokuhlasela kwaye isiqwenga sevalve sisenako ukugcina imeko entle yokugquma, intlawulo eshiyekileyo kwisibambisi sombane iyakhutshwa ngenxa yokuba umbane oshiyekileyo wesiqwenga sevalve iwela ngaphantsi kwexabiso lombane elilinganiselweyo.
Umgaqo wokuSebenza we-Surgery Arrester: Xa i-Surge Arrester ivelisa amandla aphindaphindiweyo ngoku, umthamo wayo wokukhupha uhambelana nomthamo wokutshatyalaliswa kwe-Surgery Arrester kunye ne-voltage eseleyo yesilayi sevalve;xa i-overvoltage yixabiso elithile elilinganisiweyo, i-Surge Arrester iya kukhupha inani elikhulu lentlawulo nge-varistor kwi-valve isilayi ngaphandle kokuphuka.
Iimpawu
(1) Ubungakanani obuncinci, ubunzima obulula kwaye akukho ngxolo.
(2) Isakhono esinamandla sokumelana ne-voltage engaphezulu, kunye nobuchule obuhle bokumelana nombane we-frequency frequency kunye ne-impulse current.
(3) Iya kuba nokusebenza kakuhle kombane kunye ne-thermal kunye ne-coefficient encinci kunye ne-stable yeqondo lokushisa.
(4) akukho mbane oshiyekileyo, ubomi benkonzo ende kunye nokusetyenziswa okuthembekileyo.
(5) Ukusebenza kweendleko eziphezulu kunye nokwenza lula.
Njengesixhobo sokukhusela i-voltage kwi-system yamandla, i-ZnO arrester idlala indima ebalulekileyo ekusebenzeni okukhuselekileyo kwezixhobo zombane kunye negridi yamandla.Ngophuhliso lwamandla ombane kwilizwe lethu, ukusetyenziswa kwe-MOA kuya kuba kubanzi ngakumbi.Kwinkqubo yokufaka isicelo, kufuneka siqinise ukuhlalutya kokusebenza kombambeli, siphucule iteknoloji yokufakela kunye nomgangatho wokugcinwa, ukuphepha ukusilela komonakalo wezixhobo ngenxa yezizathu zobugcisa, kwaye siqinisekise ukusebenza okukhuselekileyo nokuthembekileyo kwezixhobo zombane kunye negridi yamandla.
