变压器感应耐压试验中的计算与分析

The Calculation & Analysis of Transformer in the Inducing Withstand Voltage Test

在电力生产中,变压器的感应耐压试验是一项重要的试验,但由于变压器绝缘结构不同,其试验方法和要求也不相同,这就使变压器绕组在试验电压下的电压分布关系变得比较复杂。本文通过生产中的一个试验实例,从试验理论的角度,对变压器绕组在感应耐压试验中的电压分布关系进行分析与计算,论述了如何正确进行感应耐压试验的接线问题,并提出试验中的操作注意事项。

In the power production, the inducing withstand voltage test of transformer is very Important. But because of the different structure of the transfomer＇s insulation, its experimental methods ＆ requirements are also different, which makes the voltage distribution of transformer＇s winding complex under the experimental voltage, From the point of view of the trial theory, the essay calculates ＆ analyses the voltage distribution oftransformer＇ s winding in the inducing withstand voltage test by an experimental examplein the power production and discusses how to have correct connection in the indueing withstand voltage test and brings up the matters needing attention in the experimental operations, which plays an important role for the examiners to draft the experimental plan of the inducing withstand voltage test of transformer .
