Guano flashover muaj ob hom: ib qho yog qhov flashover tshwm sim los ntawm tsub zuj zuj ntawm insulator nto.Txawm li cas los xij, vim tias cov noog sib cais los ntawm ntau ntu los ntawm lub kaus mom insulator, qhov tshwm sim ntawm kev ncaj qha flashover yog tsawg heev.Lwm qhov yog guano slippage rwb thaiv tsev ntog nyob rau hauv lub cheeb tsam sab nrauv, lub nucleus ncaj qha ua rau luv luv-circuit tso tawm ntawm lub sab sauv thiab qis kub cov cuab yeej, thiab tsis muaj guano ib tug nyob rau hauv lub sueko, uas kuj yog lub ntsiab daim ntawv ntawm guano flassing.Raws li lub hauv paus ntawm kev ua tau zoo simulating qhov tshwm sim flashover ntawm insulator noog, lub tuam tsev ntawm hluav taws xob engineering ntawm tsinghua university tau kawm lub flashover mechanism thiab flashover tej yam kev mob ntawm guano, thiab txiav txim siab hais tias lub caij nplooj zeeg ntawm guano aberrates hluav taws xob teb faib nyob ib ncig ntawm lub insulator, ua rau. huab cua sib txawv ntawm guano channel ntawm qhov kawg ntawm rwb thaiv tsev, yog li ua rau flashover ntawm insulator.Noj 110 kv hluavtaws suozi ua piv txwv, lub voj voog nrog ib txoj kab uas hla ntawm 55cm yuav tsum tau tiv thaiv los ntawm fantian.Nyob rau tib lub sijhawm, xav txog cua guano yuav poob zoo li parabola.Hauv kev ua haujlwm tiag tiag, thaj tsam crossarm nyob rau sab saum toj ntawm tus pej thuam yuav suav tias yog tus yuam sij rau kev tiv thaiv noog nyob rau hauv thaj tsam ntawm 30-45 ° nrog cov hlua insulator raws li lub hauv paus taw tes thiab lub kaum sab xis ntawm ob sab.Qhov thib ob, cov noog pos kom ntseeg tau tias qhov ntom ntom, cov noog ua tiav "plug" sab nraum qhov chaw tiv thaiv.

Hauv daim ntawv thov engineering, vim yog hom ntauwd, qee qhov chaw tseem ceeb ntawm kev tiv thaiv noog yuav raug tso tseg, uas ua rau muaj qhov tshwm sim ntawm qhov tsis zoo ntawm cov noog puas.Cov noog spikes saum lub insulator ntawm peb-theem xaim yog ntsia rau hauv qhov chaw, tab sis cov noog pos tsis tau ntsia rau hauv av ncej saum toj ntawm sab hlau, uas tawm hauv qhov teeb meem rau qhov tshwm sim ntawm qhov txhaum.
