Guano flashover ine mafomu maviri: imwe ndeye flashover inokonzerwa nekuunganidza kwe insulator pamusoro.Zvisinei, nokuti shiri dzinoparadzaniswa nezvikamu zvakasiyana-siyana neamburera ye insulator, mukana wekuti flashover yakananga yakaderera zvikuru.Imwe yacho ndeye guano slippage insulation inowira munzvimbo yekunze, iyo yakananga nucleus inotungamira kupfupi-circuit kubuda pakati pepamusoro nepasi maturusi egoridhe, uye hapana guano traces inosiiwa pasueko, inova zvakare nzira huru yeguano flassing.Pahwaro hwekubudirira kutevedzera chiitiko cheflashover cheshiri dzinodzivirira shiri, dhipatimendi remagetsi engineering yeTsinghua yunivhesiti yakadzidza flashover mechanism uye flashover mamiriro eguano, uye yakagumisa kuti nguva yekudonha yeguano inokanganisa kugovera kwemagetsi kutenderedza insulator, zvichikonzera. mhepo gap kuparara kweguano chiteshi pamucheto wepamusoro wekuisa, zvichitungamira kune flashover ye insulator.Tichitora 110 kv synthetic suozi semuenzaniso, denderedzwa ine dhayamita ye55cm inofanira kuchengetedzwa nefantian.Panguva imwecheteyo, funga kuti mhepo guano ichadonha separabola.Mukushanda chaiko, nzvimbo yakachinjika pamusoro peshongwe ichaonekwa sekiyi yekudzivirira shiri mukati mehupamhi hwe30-45 ° ine insulator tambo senheyo point uye Angle pakati pemativi maviri.Chechipiri, shiri munzwa nechokwadi imwe density, shiri zvachose "plug" kunze kudzivirira zone.

Mukushandiswa kweinjiniya, nekuda kwemhando yakaoma yeshongwe, dzimwe nzvimbo dzakakosha dzekudzivirira shiri dzinogona kusara kumashure, zvichikonzera kuitika kwekukanganisa kwekukuvadzwa kweshiri.The Shiri spikes pamusoro insulator ari matatu-phase waya inoiswa panzvimbo, asi shiri munzwa haana kugadzika pasi danda pamusoro divi waya, iyo inosiya yakavanzwa dambudziko nokuda kuitika kukanganisa.
