Movable oil-gas monitoring data remote transmission system

Abstract

The invention discloses a movable oil-gas monitoring data remote transmission system, and belongs to the field of research on power equipment state monitoring and fault diagnosis. The movable oil-gas monitoring data remote transmission system comprises a gas-in-oil monitoring terminal device, a serial communication interface, an information collector, an operation processing unit, a data storage unit, a GPRS communication module and a remote receiving terminal. Through the interconnection of the equipment and the transmission of information, information can be sent to multiple remote receiving terminals via an APN private network, thus facilitating the timely grasp of equipment state data; and the conventional detection period is shortened, latent fault is found and the defect evolution trend is tracked.

Description

technical field [0001] The invention belongs to the field of research and application of state monitoring and fault diagnosis of electric equipment, and in particular relates to a mobile oil and gas monitoring data remote transmission system. Background technique [0002] The transformer is the key equipment in the power grid, and the insulating oil is the key medium inside the transformer. When the transformer has an electrical or thermal failure, it will be combined under complex chemical reactions to form hydrogen and low molecular hydrocarbon gases, which will be dissolved in the oil. Therefore, the composition and content of dissolved gas in transformer oil are closely related to the type and severity of equipment failure. In response to this phenomenon, domestic and foreign companies have produced and deployed many fixed and a small amount of movable dissolved gas monitoring devices in oil, which have played an important role in ensuring the reliable operation of tran...

Problems solved by technology

[0004] 1. The signal channels, collection devices, data uploading and storage formats are different, which fail to meet the requirements of accessing the substation comprehensive automation system and the power comprehensive data network. It is difficult to effectively collect data and carry out remote centralized monitoring, which affects the full play it should work

[0005] 2. The site situation of the substation is complicated, it is difficult to transform the integrated automation system and the integrated power data network interface, and the implementation period is long, and the change of the gas in the oil must be grasped in time after the transformer equipment is abnormal; thus affecting the effect of its real-time monitoring

[0006] The above problems lead to the fact that most of the existing technical products are isolated detection devices, which cannot form real-time monitoring including detection, diagnosis, data storage, comparison, query and upload
