Abstract

The invention discloses a device for detecting fracture and electric leakage of a power transmission cable, and the device comprises a work box which is internally provided with a work cavity, the work cavity is internally provided with two work box grooves which are in bilateral symmetry, and the two work box grooves are internally in sliding connection with an electric wire passing through the work cavity. According to the invention, whether the power transmission cable is insulated, aged and leaks electricity due to long-term repair loss or not is repeatedly checked through the checking device, and whether the power transmission cable is tightened or not or whether the power transmission cable is not tightened and is in a broken state or not is detected through the detection device; andthe reminding device gives out light to remind pedestrians and constructors when the checking device detects that the power transmission cable leaks electricity or the detection device detects that the cable is not tightened and is in a broken state, so that unnecessary personal accidents are avoided.

Description

technical field [0001] The invention relates to the related field of electrical equipment, in particular to a device for detecting breakage and leakage of power transmission cables. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. [0003] Power cables are all erected outdoors, and many parts are located in densely populated cities. After a long period of exposure to wind and sun and various bad weather, power transmission cables will inevitably have safety hazards such as insulation aging or breakage. Events that cause accidents. Contents of the invention [0004] Technical problem: After a long period of exposure to wind and sun and various ...
