The wind-drift-resistant insulator mounting device has the advantage that the wind-drift-resistant insulators with line turning angles larger than 45 degrees can be mounted by the aid of the wind-drift-resistant insulator mounting device.

Description

technical field [0001] The invention belongs to the technical field of special equipment for power transmission lines, and in particular relates to a jumper windproof insulator installation device in an angle steel tower of a power transmission line. Background technique [0002] When carrying out high-voltage power transmission, when the current reaches the tension rod through the wire, it is necessary to jump over the tension insulator and the iron tower through the jumper to continue the power transmission from the other side. Wind deflection insulators are suitable for hard jumper wires on high-voltage lines. They can effectively prevent jumper wires from wind deflection, and wires dance with the wind, ensuring the insulation distance between phase and ground. They are also called hard jumper insulators. It can effectively prevent line tripping, wire arc burns, broken strands, and broken wires caused by wire jumpers, and can solve the important hidden dangers of wire dan...

Problems solved by technology

However, this method can only be used for towers with line turning angles less than 45 degrees, and angle steel towers greater than 45 degrees cannot use supporting crossarms because of the angle relationship between the overhead lightning conductors, and the supporting crossarms and lightning conductors will collide Not available

Under severe natural weather conditions such as strong winds, the possibility of jumper wires discharging to the tower body, causing line tripping and burning equipment, and other vicious accidents is likely to increase, and the wind deflection insulators are mostly fixed installation dead points, and the insulators cannot swing
