摘要
近年来,随着我国经济水平的不断提高,在一定程度上推动了各行业的快速发展,促使电力能源已经成为人们生产生活中必备的能源保障.基于此人们对电力供应的安全性及稳定性等质量问题的要求也越来越高.而变压器作为电力系统的基础设备,其运行质量以及使用性能直接影响着整个电力系统.变压器的稳定性试验为其顺利投入使用提供了保证,同时也是校验变压器保护装置的重要方法.在面对大型电力系统的大容量、高电压的变压器稳定性试验,经常出现在一次通流的过程中没能顺利通过,二次通流时由于电流很小常用变压器保护装置无法识别,或者测量电量的伏安相位仪表上的数据不够精准等问题,为此本文首先介绍了变压器在电力系统中的影响及作用,然后再通过进行稳定性试验的方法加大二次电流效率,以便更好的解决问题.
In recent years,with the steady improvement of China’s economic level,it has also promoted the rapid development of various industries to a certain extent.In particular,power resources have become the necessary energy guarantee for people’s production and life.Based on this,people have higher and higher requirements for quality issues such as power safety and stability.As the basic equipment of the power system,the quality and performance of the transformer will directly affect the entire power system.The stability test of the transformer provides the basic conditions for the smooth commissioning of the transformer,and is also an important method for verifying the transformer protection device.In the face of large-scale power systems,large-capacity,high-voltage power transformers often fail to pass during the primary fl ow.Because the current is small during the secondary fl ow,the common transformer protection devices cannot be identifi ed,or Problems such as inaccurate data on the volt-ampere phase meter for measuring electricity,for this purpose this article fi rst introduces the impact and role of the transformer in the power system,and then increases the secondary current effi ciency by performing a stability test in order to better Problem solving.
