摘要
针对目前变电站在线气相色谱仪检测准确率低、光声光谱仪测量精度和反演精度低等问题,研制了由油气分离装置、光声系统、H2传感器、电子系统组成的变压器油中溶解气体光声光谱在线检测装置,并在220 kV薛家湾变电站2号变压器投入使用。实际使用情况表明,该装置运行稳定,可以准确测出变压器运行过程中油中溶解气体的类型和含量,能够有效提高变压器油质的管理水平,为设备的正常运行提供保障。
Aiming at the problems of low detecting accuracy of online gas chromatographs,low measurement accuracy and inversion accuracy of photoacoustic spectrometers in substations,Inner Mongolia Electric Power Research Institute has specially developed a set of photoacoustic spectrum online detecting device for dissolved gas in transformer oil,which is mainly composed of oil⁃gas separation device,photoacoustic system,hydrogen sensor,electronic system.This device has been put into operation for nearly one year in No.2 Transformer of 220 kV Xuejiawan Substation of Xuejiawan Power Supply Bureau.The device runs stably according to the actual use situation,and all the measurement results of the device are accurate,which can accurately measure the type and content of dissolved gas in the oil during the operation of the transformer,effectively improve the management level of the transformer oil quality,and provide a guarantee for the normal operation of the equipment.
