Uhlu oluqhelekileyo lwezixhobo zokuthintela umbane.

Kukho iintlobo ezininzi zeizinto zokuthintela imibane, kuquka izibambisi zesinyithi, izibambisi zesinyithi, izibambisi zesinyithi ezingenazikhewu, izibambisi zesinyithi ezigqunyiweyo ngokupheleleyo, kunye nezibambisi ezisuswayo.

Iintlobo eziphambili zezithinteli zezithinteli zetyhubhu, izithinteli zevalvu kunyeizithinteli ze-zinc oxideUmgaqo oyintloko wokusebenza kohlobo ngalunye lwesithinteli sombane wahlukile, kodwa intsingiselo yaso yokusebenza iyafana, konke oku kukhusela intambo yonxibelelwano kunye nezixhobo zonxibelelwano ekonakaleni.

Isithinteli setyhubhu
Isixhobo sokumisa ityhubhu ngokwenene sisithuba sokukhusela esinamandla aphezulu okucima i-arc. Sineendawo ezimbini ezilandelelanayo. Esinye isithuba sikwimo engqongileyo, esibizwa ngokuba yi-outer gap. Umsebenzi waso kukwahlula i-voltage yokusebenza nokuthintela umbhobho wokuvelisa igesi ukuba ungangeni kumbhobho. Esesibini sitshiswa yi-power frequency leakage current; esinye sifakwe kumbhobho womoya kwaye sibizwa ngokuba yi-internal gap okanye i-arc extinguishing gap. Umthamo wokucima i-arc wesixhobo sokumisa ityhubhu unxulumene nobukhulu bombane oqhubekayo. Esi sisithinteli sokukhanyisa ityhubhu esikhuselayo, esisetyenziswa kakhulu kukhuseleko lombane kwimigca yombane.

Isithinteli sohlobo lwevalvu
Uhlobo lwevalvuumbanjwayenziwe ngesithuba sentlantsi kunye nesithinteli sepleyiti yevalvu. Izinto ezisetyenziswa kwi-resistor yepleyiti yevalvu yi-silicon carbide ekhethekileyo. Isithinteli se-valve chip esenziwe nge-silicon carbide sinokuthintela ngempumelelo umbane kunye nombane ophezulu, kwaye sikhusele izixhobo. Xa kukho umbane ophezulu, isithuba sentlantsi siyaqhekeka, ixabiso lokuxhathisa lokumelana nepleyiti yevalvu liyehla, kwaye umbane wombane ungeniswa emhlabeni, okhusela intambo okanye izixhobo zombane ekonakaleni kombane wombane. Kwiimeko eziqhelekileyo, isithuba sentlantsi asiyi kwaphulwa, kwaye ixabiso lokuxhathisa lokumelana nepleyiti yevalvu liphezulu, elingayi kuchaphazela unxibelelwano oluqhelekileyo lomgca wonxibelelwano.

Isithinteli se-zinc oxide
Isithinteli sombane se-zinc oxideSisixhobo sokukhusela umbane esisebenza kakuhle kakhulu ekukhuseleni, ubunzima obulula, ukumelana nongcoliseko kunye nokusebenza okuzinzileyo. Ngokuyintloko sisebenzisa iimpawu ezilungileyo ze-volt-ampere ezingezizo ezingqalileyo ze-zinc oxide ukwenza umsinga ohamba kwi-arrester ube mncinci kakhulu (inqanaba le-microamp okanye i-milliampere) kwi-voltage eqhelekileyo yokusebenza; xa i-overvoltage isebenza, ukumelana kuyehla kakhulu, kukhuphe amandla e-overvoltage ukuze kufezekiswe isiphumo sokukhusela. Umahluko phakathi kolu hlobo lwe-arrester kunye ne-arrester yendabuko kukuba ayinayo i-discharge gap kwaye isebenzisa iimpawu ezingezizo ezingqalileyo ze-zinc oxide ukukhupha nokuqhekeza.

Eziliqelaizinto zokuthintela imibanezichazwe apha ngasentla. Uhlobo ngalunye lwe-arrester luneenzuzo kunye neempawu zalo. Kufuneka lusetyenziswe kwiindawo ezahlukeneyo ukuze kufezekiswe isiphumo esihle sokukhusela umbane.
