An energy harvesting device for power grid and its use method

Abstract

The invention belongs to the technical field of power grid, and specifically relates to an energy collection device for power grid, which includes a sliding unit and a crank connecting rod mechanism installed above the power tower, a cable seat is fixed on the upper part of the sliding unit, and the cable seat and the crank connecting rod mechanism move Connection, the crank linkage mechanism outputs torque, the sliding unit is equipped with a buffer detection unit, the cable passes through and is fixed on the cable seat; the swing energy of the cable can be used to collect the swing energy of the cable, and the cable and the cable seat can be improved at the same time service life. The present invention also provides a method for using the energy harvesting device, including the steps of equipment installation, energy conversion and collection, and electromagnetic induction buffer monitoring. At the same time, through the electromagnetic induction principle of the buffer detection unit, the cable shaking is monitored, and the tensile stress on the cable should be reduced to improve the service life of the cable.

Description

technical field [0001] The invention belongs to the technical field of electric power grids, and in particular relates to an energy collection device for a power grid and a method for using the same. Background technique [0002] With the rapid development of cities, it is more and more common to use high-voltage power cables for high-power power transmission in cities. The use of 110kv and 220kv high-voltage cables for power transmission in power systems has become the mainstream between urban areas. [0003] A large number of overhead cables are popularized and used in power systems. Overhead power cables have always been an important part of power systems. Therefore, for overhead cables in areas with high wind power all the year round, overhead cables often have a large swing. There are certain security risks in the transmission and the service life of the product. [0004] Aerial cables have a series of advantages such as convenient erection, low investment, large trans...

AI Technical Summary

Problems solved by technology

[0009] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an energy harvesting device for power grids, which is used to solve the problem that the existing cable support cannot use the swing of the cable to realize the collection of the swing energy of the cable; Existing cable supports cannot detect the swinging range of the cable at the same time and understand the force of the cable; the existing cable supports cannot reduce the tension of the cable support on the cable and the tensile stress on the cable, and the service life of the cable and the cable seat limited problems, the present invention also provides a method for using the energy harvesting device
