Izidingo zokusebenza kukagesi wesivikeli se-surge 1. Vimbela ukuthintana ngqo Lapho i-voltage ephezulu eqhubekayo yokusebenza engu-Uc yesivikeli sokuhlinza esifinyelelekayo ingaphezu kwevelu ye-ac rms engu-50V, lezi zizohlangabezana nezidingo ezilandelayo. Ukuze uvimbele ukuthintana okuqondile (izingxenye zokuhambisa ezingafinyeleleki), umvikeli ohlinzayo uzoklanywa ukuze izingxenye zawo ezibukhoma zingakwazi ukuthintwa lapho zifakwe ngaphansi kwezimo ezijwayelekile zokusetshenziswa. Ngokungeziwe kokuthi isivikelo sokuhlinza sibhekwa njengesingafinyeleleki, isivikelo sokuhlinza sizoklanywa ngendlela yokuthi, lapho sifakiwe futhi sinezintambo ukuze zisetshenziswe okuvamile, izingxenye ezibukhoma ngeke zifinyeleleke, ngisho nangemva kokudilizwa izingxenye ezingasuswa ngaphandle kwamathuluzi. Uxhumano phakathi kwetheminali yaphansi nazo zonke izingxenye ezifinyelelekayo ezixhunywe kuyo kuyoba okokuvimba okuphansi. Ukuthobelana kuhlolwa ngokuhlolwa. 2. I-Residual current (i-residual current) I_I-I-PE For all surge umvikelis with I-I-PE terminals, the I_I-I-PE shall be measured with all terminals of the surge umvikeli connected to the power supply of the reference test voltage (UREF) in accordance with the manufacturer's instructions Compliance is checked by a test, which is not applicable to SPDs connected only to N-I-I-PE. 3. Voltage protection level Up The limiting voltage of the surge umvikeli 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 surge umvikeli shall be able to withstand the specified discharge current without unacceptable changes in its characteristics. In addition, the voltage switch-type surge umvikeli or combined surge umvikeli shall at least be able to cut off the freewheeling current of the dry rated short-circuit current I_I-SCCR. Ukuthobelana kuhlolwa ngokuhlolwa.
