Problems solved by technology

[0002] Dynamic capacity increase technology refers to the installation of online detection devices on the transmission line to monitor the status of the conductors (conductor temperature, tension, sag, etc.) and environmental conditions (ambient temperature, sunshine and wind speed, etc.). Under the premise, the maximum allowable current carrying capacity of the conductor is calculated according to the Morgan et al. current carrying capacity model, and the hidden capacity of the line is fully utilized to increase the actual transmission capacity of the transmission line. Distributed between the iron towers, the existing online detection devices are usually installed on the iron towers. When detecting the state of the wires, it is difficult to obtain the local state of the wires. For example, the sag of the wires is easily affected by the clarity of the captured image. If there are foreign objects or abnormal defects in the high-voltage wires, the effect of dynamic capacity increase will be adversely affected. Under the premise of ensuring safety, the existing crawling high-voltage cable status monitoring device cannot solve the above problems , for this reason, the present invention proposes a crawling high-voltage cable condition monitoring device

Abstract

A crawling type high-voltage cable state monitoring device provided by the present invention comprises a processor, an upper half shell, a lower half shell, a left attaching crawling pipe and a right attaching crawling pipe, the left attaching crawling pipe and the right attaching crawling pipe each comprise an upper half pipe and a lower half pipe, and a plurality of rubber crawling wheels are movably embedded in the outer side of each of the upper half pipes and the lower half pipes. The creeping type high-voltage cable state monitoring device is reasonable in design, the left attaching creeping pipe and the right attaching creeping pipe are matched to enable the whole creeping type high-voltage cable state monitoring device to be attached to a high-voltage cable to creeping bidirectionally, on one hand, the state and environmental conditions of local parts of the high-voltage cable can be monitored in real time, and the whole wire can be patrolled and monitored; therefore, a more accurate state value of the high-voltage line is obtained, so that the actual maximum allowable current-carrying capacity of the lead is obtained, the actual transmission capacity of the power transmission line is improved on the premise of ensuring safety, and danger caused by poor local state or lead damage is prevented.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and particularly relates to a crawling type high-voltage cable state monitoring device. Background technique [0002] Dynamic capacity expansion technology refers to the installation of online detection devices on transmission lines to monitor the conductor status (conductor temperature, tension, sag, etc.) and environmental conditions (ambient temperature, sunshine and wind speed, etc.) Under the premise, the maximum allowable current carrying capacity of the wire is calculated according to the Morgan equal current carrying capacity model, making full use of the implicit capacity of the line, and improving the actual transmission capacity of the transmission line, which has strong practicability. The transmission lines are all sections. Distributed between each tower, the existing on-line detection device is usually installed on the tower, when the state of the wire is detected,...
