The difference between high voltage fuse XRNT and XRNP
XRNT is generally used to protect transformers, and XRNP is generally used to protect transformers. XRNT’s fusion tubes have relatively large currents, and XRNP’s have small currents such as 0.5A or 1A. The commonly used specifications are different. The size of the fusion tube is also different , The matching seat is also different, the XRNT one is bigger. The fuse tube of XRNP is relatively small.

High-Voltage Current Limiting Fuses
High-voltage current-limiting fuses are suitable for AC 50HZ, rated voltage 3.6-12KV systems, and can also be used in conjunction with other electrical appliances (such as switches, contactors, etc.) as overload or short-circuit protection for electrical equipment such as motors, transformers, and capacitors, etc. Protect.

Function and principle of lightning arrester for high voltage transmission line
The electric energy we use every day is transmitted from far away through the transmission line. Since the transmission line is very long, it will be affected by lightning strikes. Therefore, the accidents of power transmission failure are also increasing day by day, which seriously affects the electrical equipment. and people's normal production and life.

How to use a multimeter to check if a fuse is broken?
1. Whether it is AC or DC, first switch the multimeter to the corresponding voltage position, first check the voltage of the pile heads on the two fuses, if normal, it means there is no problem with the power supply, and then check the voltage of the pile heads on the two fuses. If the voltage is the same as the upper pile head, there is no problem with the fuse. If the lower pile head detects no voltage, it can be concluded that one fuse is burned or both fuses are burned.

What are the influencing factors of voltage transformer high voltage fuse?
Voltage transformer is an important device in the power system, and its main function is to measure and protect the power system. The equipment has been installed and used in excitation systems, measuring instruments, speed regulators and other electrical equipment. Voltage transformers and high voltage fuses are common accidents in power systems. When the high-voltage fuse of the voltage transformer blows, it will have a serious impact on the safety of the voltage transformer and the measurement of electricity bills. The maintenance and replacement of the high-voltage fuse is also troublesome.
