oorsig
MLY1-100-reeks Surge Protector (hierna verwys as SPD) is geskik vir IT, TT, TN-C, TN-S, TN-CS en ander kragvoorsieningstelsels van lae-spanning AC-kragverspreidingstelsels, en is geskik vir indirekte weerlig en direkte weerlig-effekte of ander beskerming teen oorgangsopvaart. Klas LL-oplewingbeskerming volgens IEC61643-1: 1998-02 Standaard. Klas B -opleweringsbeskermer SPD het die gewone modus (MC) en Differensiële modus (MD) beskermingsmetodes.
SPD voldoen aan GB18802.1/IEC61643-1.
werkbeginsel
In the three-phase four-wire system,there are protectors between the three phase lines and one neutral line to the ground line(see Figure 1).Under normal circumstances,the protector is in a high-resistance state.When thereisa surge overvoltage in the power grid due to lightning strikes or other reasons,the protector will be turned on quickly in nanoseconds,and the surge overvoltage will be introduced into the ground, thus protecting the power rooster. Elektriese toerusting. As die oplewingspanning deur die beskermer beweeg en verdwyn, keer die beskermer terug na die weerweerstandstoestand, en beïnvloed dit dus nie die normale werking van die kragnet nie.
