| titleOfInvention | A hydrogen sensor for on-line monitoring of hydrogen concentration in an oil-immersed transformer and its application method |
| abstract | The invention relates to a hydrogen sensor for on-line monitoring of hydrogen concentration in oil-immersed transformers and a method for using the hydrogen sensor. The sensor includes a hydrogen sensitive probe. The hydrogen sensitive probe includes a hydrogen sensitive chip in direct contact with transformer oil. The hydrogen sensitive chip includes a base, a device The electrical insulating layer on the base and the hydrogen sensitive element arranged on the electrical insulating layer, the surface of the hydrogen sensitive element is provided with a hydrogen-specific coating for inhibiting the diffusion of gas molecules other than hydrogen. The sensor of the present invention can be directly in contact with the transformer oil, eliminating the oil - gas separation device, improving the reliability of the sensor, and reducing the maintenance cost ; The cross-response of C 2 H 4 and other fault gases can continuously and reliably monitor the hydrogen concentration and its change rate in transformer oil, and provide a reliable basis for accurately understanding the operating status of the transformer. |
