RN2, RN3 Series indoor AC high-voltage current-limiting fuses
 
1. Product Description
        RN2,RN3 Series indoor AC high-voltage current-limiting fuses are single-phase high-voltage electrical equipment, for rated voltages of 3 ~ 35KV three-phase AC 50Hz power system, as the voltage transformer voltage power devices and other electrical equipment overload or short circuit protection.
 
2. Structure Introduction
        Fuse from the undercarriage, post insulator, static contact seat and special melt melting tube is wound on a hexagonal mandrel, and filled with quartz sand in the pipe, copper cap and end caps at both ends by soldering to remain sealed. When the line fault current outlet is the melt melting, arc quickly extinguished in the role of quartz sand. Because of limiting the role of quartz sand, before the short-circuit current peak has been broken open, thus limiting fuse has a strong capacity and short open time, thus ensuring the voltage transformer from damage.
