Aging Mechanism and Countermeasures of Surge Protective Devices in Transmitter Lightning Protection Systems
The transmitter has special structure and high working voltage,which is easy to be attacked by lightning disaster.In order to ensure that the transmitter is protected from lightning damage,it must be equipped with a perfect and reliable lightning protection system.The surge protection device is the key component.Aging and degradation of surge protection devices will lead to cascading failure of lightning protection system,resulting in serious consequences such as equipment burnout and fire.In this paper,the classification of surge protection devices and their main performance parameters are introduced.From four aspects:optimizing device selection and configuration,strengthening environmental management monitoring,establishing regular detection and maintenance mechanism,and developing new anti-aging devices,countermeasures are proposed to delay the aging of surge protection devices and improve the reliability of lightning protection system.
