In actual operation, the telescopic cable clamp supported by the pipe mother is similar to a shock absorber in the interconnection equipment. The dynamic characteristics and earthquake response of the interconnected high-voltage equipment connected by the pipe busbar have a great influence. If only the pipe mother support telescopic clamp is simulated as a horizontal sliding support, there is a big difference from the actual force of the pipe support telescopic clamp
In the simulation, if the influence of these hysteresis characteristics of the pipe support expansion clamp on the dynamic characteristics of the interconnected equipment and the earthquake is ignored, the accuracy of the simulation will be seriously affected

Description
technical field [0001] The invention relates to the technical field of electric power systems, in particular to a device and method for predicting hysteretic characteristics of telescopic wire clips supported by a pipe support. Background technique [0002] In the simulation calculation of the interconnected simulated high-voltage electrical equipment, the seismic load acts repeatedly on the interconnected equipment. In this simulation, the pipe support telescopic clamp is only simulated as a horizontal sliding support. In actual operation, the telescopic cable clamp supported by the pipe mother is similar to a shock absorber in the interconnection equipment. The dynamic characteristics and seismic response of the interconnected high-voltage equipment connected by the pipe busbar have a great influence. If only the pipe mother support telescopic clamp is simulated as a horizontal sliding support, there is a big difference from the actual force of the pipe support support tel...
