摘要
A DIELECTRIC PROTECTIVE COVER FOR A LIGHTNING ARRESTER WITH AN EARLY STREAMER EMISSION DEVICE COMPRISING AN ACTIVE PORTION CONNECTED TO THE EARLY STREAMER EMISSION DEVICE TO FACILITATE THE TRIGGERING OF AN UPWARD LEADER FROM THE ACTIVE PORTION, A DOWN CONDUCTOR TO BE GROUNDED, AND A DIELECTRIC PORTION THROUGH WHICH THE ACTIVE PORTION IS MOUNTED ON THE DOWN CONDUCTOR. THE ACTIVE PORTION IS SEPARATED FROM THE DOWN CONDUCTOR BY AN AIR SPACE TO FORM BETWEEN THEM A SPARK GAP THROUGH WHICH THE LIGHTNING CURRENT PASSES FROM THE ACTIVE PORTION TO THE DOWN CONDUCTOR. THE PROTECTIVE COVER IS DESIGNED TO BE ATTACHED TO THE LIGHTNING ARRESTER TO PROTECT THE SPARK GAP AGAINST DEGRADATION OF ITS DIELECTRIC PROPERTIES BY THE ENVIRONMENT WHILE LEAVING THE ACTIVE PORTION OF THE LIGHTNING ARRESTER EXPOSED TO THE ENVIRONMENT.
