Embodiment Construction

[0101] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0102] In addition, it should be noted that, unless otherwise specified or pointed out, the terms "left", "right", "upper", "lower" and other descriptions that may be involved in the specification are only used to distinguish the various components, elements, Steps, etc., rather than expressing the logical relationship or sequence relationship between components, elements, and steps.

[0103] Such as figure 1 As shown, a high-voltage line fall prevention device includes an electric wire 710, which is hung on the upper part of the pole 700, and also includes:

[0104] The pulley block 100 is hung on the electric pole 700 above the electric wire 710, wherein t...

Abstract

The invention relates to equipment for preventing fall of high voltage line, which comprises an electric wire hanged on the top of poles, pulley blocks hanged on the poles, and a tensioning rope connected between the pulley blocks. A breaker is connected in series between the tensioning ropes; traction ropes are connected between the tensioning rope and the breaker; a net pocket is arranged between the poles and under the electric wire; and storage boxes are arranged below the pulley blocks. The invention also discloses a using method. According to the equipment for preventing fall of high voltage line and the using method, the possibility of electric wire breakage can be reduced, and an alarm occurs when the electric wire breaks, thus the electric wire is powered off, and the electric wire is gathered to prevent danger from the electric wire breaks, and falls on the ground.

Description

technical field [0001] The invention belongs to the technical field of high-voltage transmission line operation maintenance and overhaul equipment, and in particular relates to a high-voltage line drop prevention device and a use method. Background technique [0002] Power transmission is achieved by using a transformer to boost the power generated by the generator, and then connecting it to the transmission line through circuit breakers and other control equipment. According to the structural form, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. In cities, high-voltage power transmission generally uses cables with insulating layers for underground transmission, and in the wild, overhead lines carried by iron towers are often used for transmission. [0003] With ...
