Frequently Asked Questions
Q
What is the main function of the 10 kV zinc oxide arrester (model 17/50)?
The primary function of this arrester is to protect electrical equipment from overvoltage damage, including atmospheric overvoltage caused by lightning, operating overvoltage, and power frequency transient overvoltage. It is used in power systems, railway electrification systems, and communication networks to ensure stable and safe operation.
Q
Why is zinc oxide used as the core material in this arrester?
Zinc oxide resistor sheets possess outstanding nonlinear volt-ampere characteristics. This means the material maintains very high resistance under normal voltage conditions (keeping operating current at microampere level) but rapidly switches to low resistance during overvoltage events, allowing large surge currents to pass through and dissipate the excess energy effectively.
Q
How quickly does the arrester respond to an overvoltage event?
The arrester responds instantly to overvoltage conditions. Upon detection, the current surges to thousands of amperes in a very short time, enabling rapid conduction and timely dissipation of overvoltage energy to protect connected equipment from damage.
Q
What types of electrical equipment can this arrester protect?
This arrester is designed to protect a wide range of electrical equipment, including transformers, switches, capacitors, motors, mutual inductors, generators, power cables, communication power supply equipment, and signal transmission equipment — all operating within 10 kV electrical systems.
Q
Is the 10 kV zinc oxide arrester suitable for railway applications?
Yes. The arrester is specifically applicable to railway electrification systems. It safeguards the electrical components of railway power supply lines and locomotives against overvoltage, contributing to the stable and reliable operation of railway transportation infrastructure.
Q
Can this arrester be used in both industrial and commercial building environments?
Absolutely. In addition to power and railway systems, the 10 kV zinc oxide arrester (model 17/50) is well-suited for industrial and mining enterprises, high-rise buildings, and any other facilities that operate 10 kV electrical systems requiring reliable overvoltage protection.
