Introduction to Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube Arresters (GDT) are protection components that operate by passing a current through a spark gap, or a special form of resistor known as a spark gap arrester. An increased voltage occurring in the electric power system and triggering a spark will cause the gas in the spark gap to ignite, dissipating the energy before it reaches the protected equipment. This method of protection is used in various protective applications including overvoltage protection systems and surge current protection.

What is 2063-60-ALF?

2063-60-ALF is a series of spark gap GDTs designed to protect high voltage systems by providing overvoltage protection. The GDT is designed to operate both in series and parallel connections and has a fixed resistance. It has a wide operating temperature range (from -40°C to +85°C) and is designed for applications with up to 12 kV.

Application Field

2063-60-ALF is widely used in high voltage power systems where large-scale induced surges, transients, and impulse surges occur. Its main application field includes power transmission and distribution systems, electronic power supplies, battery backup systems, communication networks, railroad systems, and lightning protection systems.

Working Principle

The 2063-60-ALF series of GDTs operate on basic spark gap arrester principles. The spark gap is made of two electrodes connected by a special dielectric gas, typically sulfur hexafluoride (SF6). When an external voltage is applied across the electrodes, the gas ionizes, allowing current to be discharged in proportion to the magnitude of the electric field. The spark gap arrester is triggered when the voltage reaches a certain breakover voltage, based on the characteristics of the spark gap. Once triggered, the current is then dissipated or absorbed by the spark gap, absorbing the energy before it reaches the protected equipment.

Conclusion

In conclusion, the 2063-60-ALF spark gap arrester is a reliable solution for providing overvoltage protection in high voltage systems. It is designed to work in both series and parallel connections, with a wide operating temperature range and voltage of up to 12 kV. The working principle is based on the basic principles of spark gap arresters, where the spark gap is made of two electrodes connected by a special dielectric gas which ionizes when an external voltage is applied, allowing current to be discharged in proportion to the magnitude of the electric field.
