Iimfuno zokusebenza zombane zomkhuseli wokunyuka 1. Thintela uqhagamshelwano oluthe ngqo Xa owona mbane uphezulu uqhubekayo osebenzayo we-Uc womkhuseli wokutya okufikelelekayo ungaphezulu kwexabiso le-acrms le-50V, ezi ziya kuhlangabezana nezi mfuno zilandelayo. Ukuthintela uqhagamshelwano oluthe ngqo (iindawo zokuqhuba ezingenakufikeleleka), umkhuseli wokunyuka uya kuqulunqwa ukuze iindawo zakhe eziphilayo zingenakuchukunyiswa xa zifakwe phantsi kweemeko eziqhelekileyo zokusetyenziswa. Ukongeza kumkhuseli wokutyanda ochazwe njengongenakufikeleleka, umkhuseli wotyando uya kuyilwa ukuze, xa efakelwe kwaye efakwe iingcingo kusetyenziso oluqhelekileyo, iindawo eziphilayo aziyi kufikeleleka, nasemva kokudilizwa kweendawo ezinokususwa ngaphandle kwezixhobo. Uqhagamshelo phakathi kwetheminali yomhlaba kunye nazo zonke iindawo ezifikelelekayo eziqhagamshelwe kuyo ziya kuba yi-impedance ephantsi. Ukuthobela kuhlolwa ngovavanyo. 2. Intsalela yangoku (intsalela yombane) I_PE Kubo bonke abakhuseli botyando abaneetheminali ze-PE, i I_PE iyakulinganiswa ngazo zonke iitheminali zomkhuseli wokutyanda eziqhagamshelwe kunikezelo lwamandla ombane wovavanyo lwereferensi (UREF) ngokuhambelana nemiyalelo yomenzi. Ukuthotyelwa kuhlolwa ngovavanyo, olungasebenziyo kwii-SPD eziqhagamshelwe kuphela kwi-N-PE. 3. Inqanaba lokukhusela umbane phezulu Umda wombane we umkhuseli wokutya should not exceed the voltage protection level specified by the manufacturer. Compliance is checked by tests. 4. Action load test When the maximum continuous working voltage Uc is applied, the umkhuseli wokutya shall be able to withstand the specified discharge current without unacceptable changes in its characteristics. In addition, the voltage switch-type umkhuseli wokutya or combined umkhuseli wokutya shall at least be able to cut off the freewheeling current of the dry rated short-circuit current I_I-SCCR. Ukuthobela kuhlolwa ngovavanyo.
