The invention discloses a steel pipe pole for preventing indirect lightning strike. The steel pipe pole comprises a pole body (1) and cross arms (2), wherein the plurality of cross arms (2) are symmetrically mounted on the pole body (1) at intervals; the steel pipe pole is characterized in that a lightning arrester (4) is mounted on the pole body (1) through an insulator (3); one end of a lower lead (5) is connected with the lightning arrester (4), and the other end of the lower lead (5) is connected with a ground electrode. The steel pipe pole disclosed by the invention is simple in structure and convenient to operate, can reduce the lightning trip-out rate of an electric transmission line, and reduces the power failure influence.
Description
technical field [0001] The invention relates to a steel pipe pole, in particular to a steel pipe pole for preventing induced lightning strikes. Background technique [0002] As we all know, the trip events of power supply lines are all caused by lightning strikes. After the line is tripped by lightning, affected by the weather and other aspects, it is difficult for the transmission inspection personnel to find the fault point on the ground at the first time. Tiandeng pole also has potential safety hazards. In addition, the power lines of the substation are mostly erected with double circuits on the same pole, and the impact of power failure is relatively large. Contents of the invention [0003] The purpose of the present invention is to provide a steel pipe pole for preventing induced lightning strikes, reduce the lightning tripping rate of power transmission lines, and reduce the impact of power failure. [0004] The technical solution of the present invention is: the...
