Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] figure 1 For the perspective view of the overall shape of the anti-shielding lightning rod, the anti-shielding lightning rod is mainly composed of upper needle body 2, lower needle body 6, vertical needle 3, horizontal needle 4, swivel joint 5, balance ball 7 and other structures. The vertical needle 3 and the horizontal needle 4 are directly installed on the upper needle body 2, and the balance ball 7 is installed on the upper needle body 2 through the connecting rod. The balance ball 7 can be adjusted according to the length of the connecting rod to achieve the overall balance effect of the shielding lightning rod . The upper and lower needles are connected by an internal locking mechanism. The upper and lower needles have a semicircular bayonet. After the upper and lower needles are closed, the anti-shielding lightning rod is locked on the ca...

Abstract

The invention discloses a lightning rod for shielding a failure of an overhead transmission line and a method. The lightning rod comprises an upper lightning rod body and a lower lightning rod body, wherein the upper lightning rod body is connected with the lower lightning rod body through a locking mechanism; the locking mechanism comprises a worm gear shaft which traverses through the inside of the upper lightning rod body and is parallel to the overhead line; the work gear shaft is meshed with a worm gear; the worm gear is arranged on a lead screw; the lead screw is matched with a screw nut which is fixed on the lower lightning rod body; the worm gear shaft is connected with a rotary joint which is located outside the upper lightning rod body and drives the upper lightning rod body to rotate; and the worm gear and a worm are driven by rotating the rotary joint to drive the screw nut to move up and down along the lead screw, so that opening and closing of the upper lightning rod body and the lower lightning rod body of the lightning rod for shielding the failure are finished.

Description

technical field [0001] The invention relates to an anti-shielding lightning rod for an overhead power transmission line, in particular to a method for an anti-shielding lightning rod for an overhead power transmission line suitable for loading and unloading by a robot. Background technique [0002] Overhead transmission lines are an important part of the power grid, and their operational reliability is directly related to the safety and stability of the entire power grid. According to the classification and statistics of power grid faults in the world, the number of trips caused by lightning strikes on high-voltage transmission lines accounts for 50% of the total trips- 60%, according to the analysis of the operation of the transmission line, a considerable number of trips are caused by lightning shielding. Especially near the high-voltage line towers of some high-voltage transmission line sections, frequent lightning strikes in thunderstorm seasons cause power grid tripping...
