通过气相色谱分析变压器的潜伏性故障

摘要

利用气相色谱法预测变压器的潜伏性故障是通过定性、定量分析溶于变压器油中的气体来实现的。由于故障气体的组成和含量与故障的类型和故障的严重性有密切关系，所以定期分析溶解于变压器油中的气体就能及早发现变压器内部存在的潜伏性故障，并随时掌握故障的发展程度。通过一些成熟的分析方法，就能够充分掌握变压器的运行状态，提早发现变压器内部故障并给与准确的故障诊断，防止重大事故的发生。%Through the analysis of gas dissolved in transformer oil can predict transformer latent fault.a result of dissolved gas--in-- oil composition and content and the type of fault and the fault severity are closely related,so the regular analysis of dissolved in the transformer dissolved gas--in--oil can be detected early transformer latent fault,and grasp the development is very necessary. through some mature analysis method,will be able to fully grasp the transformer running state,early detection of transformer internal fault and give accurate fault diagnosis,prevent the occurrence of major accidents.
