Protective device

Abstract

The invention discloses a protective device, which comprises a protective plate, wherein the middle of the protective plate is provided with a mounting hole, the mounting hole is internally provided with at least one concentric variable-diameter fixing ring in a sleeving manner, the variable-diameter fixing ring is connected with the mounting hole through a connecting part, the variable-diameter fixing ring is used for being matched with the diameter of a borne cable or supporting column, and when the diameter of the cable or supporting column is greater than that of the variable-diameter fixing ring, the connecting part connected with the variable-diameter fixing ring is broken off; and the protective plate is divided into a left half part and a right half part along the center line of the mounting hole, and when the left half part and the right half part are arranged on a cable or a supporting body in a sleeving manner, the left half part and the right half part are connected together. According to the invention, the diameter of the mounting hole of the protective device is changed according to the diameter of a cable or a supporting body, and the protective device has the characteristic of being suitable for cables or supporting bodies with different diameters. In addition, the contact surface of the protective device and the cable is increased, the frictional resistance isincreased, the anti-skid effect is achieved, and the cable is prevented from being scratched.

Description

Technical field [0001] The present invention relates to the field of power equipment, and in particular to a protection device for power equipment. Background technique [0002] The electrical equipment on telegraph poles or towers, as well as the electrical components of wires and high-voltage lines, are often damaged by small animals. Small animals generally climb up along the telegraph poles or cables. When they climb to the electrical equipment, they will Leading to power equipment tripping, fire and other faults, resulting in incalculable losses. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings, the purpose of the present invention is to provide a protective device that can effectively prevent small animals from climbing up along the cable or support column, and achieve effective protection of electrical equipment. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: [0005] ...
