Transformer integrated online monitoring system

The comprehensive monitoring, analysis, and diagnosis of power operation equipment have always been problems that the power sector is looking forward to solving. In particular, the accumulation of transformer operation management experience has provided a considerable amount of domain expertise and fault symptoms for the establishment of the power transformer insulation diagnosis expert system. It has been able to gradually carry out analysis, judgment, and decision-making research on the fault and life of the operating equipment, so as to reach the status Monitoring and diagnosis, the purpose of establishing a predictive maintenance system. On-line monitoring of power transformers is an important means to reflect the operating status of equipment in a timely and accurate manner. Partial discharge detection of transformers and chromatographic analysis of gas in oil are the main methods to reflect the insulation status during operation.

Transformer partial discharge online monitoring system (pulse current method)

The anti-interference effect is remarkable. Researched and developed a dual-sensor directional coupling pulse identification system (two patented technologies) with independent intellectual property rights, and comprehensively applied multiple anti-interference methods such as digital filtering, phase windowing, and dynamic threshold to effectively eliminate or suppress interference and ensure acquisition The data is accurate and reliable. According to the principle of virtual instrument, adopt PC-DAQ system structure, LabVIEW programming, and realize various functions by software. It has powerful functions, strong flexibility, easy to expand multi-parameter monitoring and multiple equipment tour monitoring, and easy to maintain and upgrade. The system is safe, stable and easy to manage.
