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.

Product description
Parameters

Partial discharge online monitoring

The minimum measurable discharge capacity is 500PC, and the measurement frequency band is 40k~3MHz.

The time resolution of the discharge pulse is 10μs; the phase resolution is 0.18°.

The measurement system can monitor the transformer discharge amplitude, phase, frequency and other parameters; can display power frequency periodic discharge diagram, two-dimensional (q-φ, N-φ, Nq) and three-dimensional (Nq-φ) discharge spectrogram; and provide Discharge trend chart, set alarm, perform historical query and print reports and other functions.

Online monitoring of gas components in oil

The combined value of the main characteristic gases hydrogen, carbon monoxide, acetylene and ethylene can be detected.

Detection Indicator
