1000kV特高压电压互感器校验电源设计

Design of 1000kV UHV voltage transformer calibration power supply

传统特高压电压互感器通常采取现场校验,由于校验所用设备的体积和重量均较大,存在运输与搭建困难、工作效率低、安全隐患大、试验准确性难以保障等问题。文中从试验原理、设备组成、各部件的设计方法等多方面进行深入的分析与研究,设计了一种新型的1000 k V特高压电压互感器校验电源。该校验电源无需搭建与停电调试,且对标准电压互感器干扰较小,实现了特高压校验电源的小型化设计。试验结果表明,文中所提设计方案有效提高了特高压电压互感器现场校验的准确性、工作效率及安全性。

Traditional UHV voltage transformer usually adopts on-site calibration.Due to the large volume and weight of calibration equipment,there are some problems,such as difficult transportation and construction,low work efficiency,large potential safety hazard,and difficult to guarantee the accuracy of test.In this paper,A new 1000 k V UHV voltage transformer calibration power supply is designed based on the in-depth analysis and research on the test principle,equipment composition,design methods of various components and other aspects.The calibration power supply does not need to be built and debugged without power failure,and has little interference to the standard voltage transformer,thus realizing the miniaturization design of UHV calibration power supply.The experimental results show that the proposed design scheme effectively improves the accuracy,efficiency and safety of on-site calibration of UHV voltage transformer,and provides key technical support for on-board calibration equipment of UHV voltage transformer.
