摘要

在气体绝缘金属封闭输电线路(GIL)条件下的电磁式电压互感器误差校验中,谐振电源系统的选配、组合是比较关键的问题。介绍了使用组合可调电抗器解决长距离GIL升压的电源系统,分析了该系统的数学模型,提出了工频谐振下相对失谐度的概念,并对制约电压增益的因素进行了分析。提出使用二次压降测试仪进行误差校验,给出了重点参数的测量方法及试验步骤。最后,以澜沧江糯扎渡水电站GIL出线互感器误差现场检测试验为例,进一步验证了该方法解决长距离GIL中电磁式电压互感器误差校验的可行性和有效性。
        In the error test of electromagnetic potential transformer in gas insulated metal enclosed transmission line(GIL),the selection and combination of resonant power system are key problems. Consequently,this paper introduced the use of combined adjustable reactor to solve the voltage boosting in GIL,and analyzed the mathematical model of the system. The concept of relative detuning at power frequency resonance was presented. The factors which restricted the voltage gain were also analyzed. In addition,the use of secondary voltage drop tester for error checking was proposed in this paper. The key parameters measurement and test steps were given. Finally,taking the error test in GIL electromagnetic voltage transformers of Nuozhadu hydropower station as an example,the experimental results have been given to verify the feasibility and validity of the proposed method.
