To Explore the Enclosed Line 330 kV Transformer Preventive Test Method of GIS

Abstract

本文对封闭式GIS出线变压器的连接结构进行分析、实践，探索出不拆除封闭气管道和高压引线的试验方法，取得表征封闭式变压器健康状态的实际数据，对试验数据分析判断，并与交接试验、同类设备试验数据进行对比，进而验证了方法的正确性和可靠性。结果表明采用的试验方法，在封闭式变压器的绝缘技术监督中能发挥很好地实用性，可以定期开展变压器的预防性试验和异常情况下的检查试验，是一种有效的电气试验方法。 This paper analyzes and practices the connection structure of the closed GIS line transformer and explores the experimental method of not dismantling closed gas pipelines and high voltage wires. The practical data for the health status of the closed type transformer are obtained. The paper analyzes and judges test data and compares test data with the data of commissioning tests and similar equipment tests. Then, it verifies the correctness and the reliability of the method. The results show that the test method used in the insulation technical supervision of the enclosed transformer can play a very good practicality. The preventive test of transformers and check tests in the abnormal situation can be carried out regularly. It is an effective electrical test method.
