Transmission conductor arbitrary deicing form simulation device and dynamic response monitoring system

Abstract

The present invention provides a transmission conductor arbitrary deicing form simulation device and a dynamic response monitoring system. A plurality of semi-automatic deicing control devices are uniformly arranged on a conductor model, and iron sheets on an interceptor plate are attracted and released by controlling power on and off of electromagnets, so that the purpose of controlling the interceptor plate to move is achieved, the staggered area of the square interception plate holes in the interception plate and the square bottom plate holes in the bottom of the cubic box can be adjusted, and partial falling, deicing at different positions, control of the deicing rate, simulation of the ice melting process and the like can be realized; by controlling the operation time difference of the adjacent semi-automatic deicing control devices, the simulation of non-synchronous deicing forms such as zipper type deicing can be realized; real-time tension data of a wire model are obtained through a tension sensor, a dynamic strain gauge and a computer; and the displacement change time history at the displacement measuring point can be obtained through a computer connected with the high-precision industrial camera.

Description

Technical field [0001] The present invention belongs to the technical field of power systems, particularly to a transmission line simulation apparatus in any form of de-icing and Dynamic Response Monitoring System. Background technique [0002] According to the National Grid Co., Ltd. from 2014 to 2018 more than 500kV transmission line failure outage statistics and found that all failures ice damage accounted for about 33.6%, which is the main reason for the jump off the ice Transmission lines' ice failure. Jumping off the ice can cause adjacent wires, flashover discharge on cables, wires broken, damaged fittings, cross arm damage, destroy towers and other serious fault, for the safe operation of the transmission line caused great harm, causing heavy economic losses and social impact. Thus the power transmission line de-icing studies ice response characteristics, provides a valid basis for the design of anti-icing grid. [0003] At present domestic and foreign scholars have been ...

AI Technical Summary

Problems solved by technology

[0003] At present, scholars at home and abroad have carried out a lot of research on the problem of icing and deicing of transmission wires, but in fact, the research methods are basically based on finite element analysis under a single ideal deicing mode, and the results obtained are often lack of verification

The monitoring of the icing and deicing process of the true transmission line can provide some data to test the current design method of the transmission line considering the icing and deicing. Line monitoring is often costly and data accuracy is difficult to guarantee
