| description | The utility model is suitable for an urban rail transit lightning protection technical field provides a spherical overvoltage protection clearance of urban rail transit contact net, include: first electrode connecting rod 1, second electrode connecting rod 2, first spherical discharge electrode 3, the spherical discharge electrode 4 of second, first holder 5 and second holder 6, first electrode connecting rod 1 is the L type with second electrode connecting rod 2, first spherical discharge electrode 3 is fixed to 1 one end of first electrode connecting rod, and other end fixed connection is on first holder 5, the spherical discharge electrode 4 of the fixed second of 2 one end of second electrode connecting rod, other end fixed connection is on second holder 6, the spherical discharge electrode 4 of first spherical discharge electrode 3 and second sets up intermediate formation overvoltage protection clearance relatively. Its gap length can have prior to the insulator flashover according to the withstand voltage level of insulator, the nimble regulation of filthy situation, shifts discharge path and protects line insulator to avoid the effect of thunder and lightning harm. |
