Protection device for preventing cable from being excessively tensioned

Abstract

The invention discloses a protection device for preventing a cable from being excessively tensioned, which relates to the technical field of power transmission cables. The device comprises a cable, acable sliding device, a cable breaking and closing device and a wire tower, wherein one end of the cable is provided with a cable joint and a plurality of fixed joints; the plurality of fixed joints are fixed on the peripheral side surface of the cable joint; the length of the cable joint is greater than that of the fixed joint; a guide block is fixed on the other end surface of the cable connecting seat; a double-sided jack line board is fixedly mounted at the top end of the wire tower; cable joints are inserted into opposite surfaces of the double-sided jack line board; and the cable joint penetrates through a cable storage groove. Through the effects of the cable, the cable sliding device and the cable breaking and closing device, the problems that the cable is broken due to too large tensioning force in extreme weather, personnel are prone to being hurt in the cable throwing process due to breaking of the cable, and even the serious consequence of collapse of the tower is caused are solved.

Description

technical field [0001] The invention belongs to the technical field of power transmission cables, and in particular relates to a protection device for preventing excessive tension of cables. Background technique [0002] The current power transmission cables are generally long in length, which results in a large weight load of the power transmission cables, and then requires relatively high strength of the cables. [0003] For example, when the wind speed in extreme weather is very high, the impact on the sway of the cable will make the tension of the transmission cable larger, and it is easy to cause a large damage to the transmission cable in a short time. impact, resulting in the phenomenon of breaking due to excessive tension, and the cable is easily injured when the line is thrown due to the break, and even the serious consequences of the collapse of the tower; all of which will cause property damage. serious loss. [0004] Aiming at the above-mentioned defects, the p...
