Internal structure of overvoltage converter

Electronic equipment and computer systems working at volt-level voltage levels are susceptible to damage by lightning strikes and overvoltage shocks caused inside and outside the equipment . For this reason, measures must be taken to prevent lightning strikes and overvoltage . In addition to installing lightning rods and lightning protection nets in buildings,
the following measures must also be taken.
    Figure 20-31 shows the lightning protection wiring on the AC power line that introduces the uninterruptible power supply UPS. Install
ZGB 148A-20 , 220V at point B ; install ZGBls3A-60, 380V power supply arrester at point A ; install ZGB235J2-24 signal arrester at point C (computer and
electronic equipment input terminal); install the ZGB235J2-24 signal arrester at the antenna entering the communication machine Install
Z GB 003E-1 feederless arrester on the introduction line (not shown in the picture). The power surge arrester (protector) is composed of several protection function blocks
.
