[0002] The hidden danger maintenance of existing transmission lines mostly relies on manual climbing and maintenance. For the power failure of replacement and maintenance, it is also necessary to manually detect whether the current is abnormal. There is a lack of special lift-type overall sensor equipment design based on current mutual inductance for high-altitude transmission line maintenance operations.

The invention discloses a lifting type sensor device for electric transmission line maintenance based on a current transformer. The lifting type sensor device comprises a lifting guide rail, a slidingbearing part, a chain transmission mechanism, a power part and a current transformer mutual inductance coil assembly, wherein the sliding bearing part is fixedly connected with the lifting guide railthrough a cross beam assembly; the sliding bearing part is connected with the power part in a matched mode through the chain transmission mechanism; the top end of the current transformer is fixedlyconnected with the bottom end of the chain transmission mechanism; the mutual inductance coil assembly is fixedly arranged below the current transformer and is electrically connected with the currenttransformer; and a power transmission cable to be detected is arranged in the mutual inductance coil assembly. According to the device, the technical defects are solved as follows: the existing powertransmission line has more hidden dangers, the maintenance mainly depends on manual climbing, whether the current is abnormal or not is also needed to be detected by manpower for replacing the electric power failure, and a special lifting type integral sensor equipment design based on current mutual inductance is lacked aiming at the maintenance operation of a high-altitude power transmission line.
Description
technical field [0001] The invention relates to a lift-type sensor device for maintenance of transmission lines based on current mutual inductance, and belongs to the technical field of sensor design. Background technique [0002] The hidden danger inspection of existing transmission lines mostly relies on manual climbing and maintenance. For power failures that need to be replaced and repaired, it is also necessary to manually detect whether the current is abnormal. There is a lack of special lift-type overall sensor equipment design based on current mutual inductance for high-altitude transmission line maintenance operations. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art, solve the above technical problems, and propose a lifting sensor device for transmission line inspection and maintenance based on current mutual inductance. [0004] The present invention adopts the following technical scheme: a lifti...
