AI Technical Summary

Problems solved by technology

Increased operating and maintenance costs of the system when said protection is used in climatic zones with high lightning rates
If overload protection cannot effectively limit voltage and current, the amount of extra circuitry in the secondary circuit increases maintenance costs
Furthermore, the mentioned cost of operational downtime is significant, since the air station or runway may be closed

Abstract

The present disclosure relates to lightning arresters for airport lighting systems and secondary circuits for airport lighting systems. A lightning arrester for an airport lighting system, wherein the airport lighting system includes a primary circuit having a plurality of transformers including primary windings and secondary windings, the primary windings of the transformers are connected in series in the primary circuit and at least one of the secondary windings of the transformers is adapted to For supplying secondary circuits of lighting equipment with airport lighting systems, wherein the arrester comprises a sealed housing for protecting the circuit of the arrester and a connector for electrically connecting the arrester to the secondary circuit, the arrester is adapted to operate at excessive voltage provides a low-impedance current path to ground.

Description

[0001] field of invention [0002] The present invention relates to airport lighting systems, and more particularly to overvoltage protection for airport lighting systems. [0003] Background of the invention [0004] An important aspect of airport or air station operations is the proper operation of the airport lighting system or Aviation Ground Lighting (AGL). For example, such lighting systems include approach and landing lighting and runway threshold lighting, runway lighting and taxiway lighting. [0005] The various components used for lighting operate under extremely severe conditions due to the large temperature fluctuations in open airports and various chemicals used in the operation and maintenance of aircraft and airports. Strict requirements are therefore set for the components of the lighting system. These components are usually installed in pits or tanks, but they can also be buried directly in the ground. In normal operation they must be fully resistant to wat...
