利用色谱分析方法对油中溶解气体进行分析,检测变压器内部早期故障,已成为变压器绝缘监督的一种重要手段。实践证明,这项检测技术的开发和应用,使变压器内部故障的检测技术取得了新的突破,特别是它可以在设备运行时进行,而且不受外界电的因素的影响,因此可以定期地对运行中的设备内部状况进行诊断,确保设备的安全可靠运行,有利于实现将主变压器的定期维修方式改革成内部状态预知维修的方式。我厂5年来的实践已充分显示了这项检测技术的实用性和可观的经济效益。
The use of chromatographic analysis of dissolved gases in oil to detect early failure within the transformer has become an important means of transformer insulation supervision. Practice has proved that this detection technology development and application of the transformer internal fault detection technology has made new breakthroughs, in particular, it can be carried out during operation of the device, and is not affected by external power factor, so you can regularly Diagnosis of the internal conditions of the equipment in operation, and ensuring the safe and reliable operation of the equipment, it is beneficial to realize the method of reforming the regular maintenance method of the main transformer into the internal state to predict the maintenance. The practice of our plant over the past five years has fully demonstrated the practicability and considerable economic benefits of this testing technology.
