特高压绝缘试验平台传动机构的动力学分析

Dynamic Analysis on Transmission Mechanism of UHV Insulation Test Platform

在现场进行交流耐压试验是检验特高压一次设备绝缘性能的重要手段。传统散装式试验设备已无法满足特高压GIS设备安装进度的要求。针对这一现状,研发出一种用于特高压一次设备现场试验的整装试验平台。文中运用解析法对该装置传动机构的液压缸推力、转弯半径、底盘轴荷以及转向阻力矩等关键参数对装置进行了分析计算;对装置的动力学特性进行了校核,验证了该装置在现场应用的可行性。文中的分析方法和结果为类似装备的研发和选型提供了理论依据。

Traditional decentralized test devices for AC voltage withstand test on site cannot meet the requirements of installation progress of UHV GIS equipment. In view of this situation, an integrated test platform for the field test of UHV equipment was developed. In this paper, the key parameters of the transmission mechanism such as the hydraulic cylinder thrust, the turning radius, the axle load of chassis and the steering resistance moment are calculated with analytic method. The dynamic characteristics of the platform are checked, and the feasibility of its application in the field is verified. The analysis method and results in this paper may be taken as a theoretical basis for development and selection of similar equipment.
