Embodiment Construction

[0019] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, it is a schematic diagram of the framework of the monitoring terminal system according to the embodiment of the present invention. A transformer operating state monitoring terminal includes a transformer operating data acquisition module, which can be realized through a transformer sampling circuit, and is used to collect signals such as load, winding temperature, top oil temperature, and on-load switch switching times under the operating state of the transformer. The sampling circuit is designed according to the operating status of the transformer that needs to be monitored. At present, the transformer operating data that usually needs to be monitored includes: the load curve of the transformer. The signal is taken from the CT used for the B-phase bushing winding thermometer, which is the 0-2A CT te...

Abstract

The invention relates to a monitoring terminal for transformer operation state, comprising: a core operation module for judging the current operation state of the transformer, a transformer operation data acquisition module electrically connected to the core operation module through an A / D conversion module, and a data storage module and the core operation module The modules are electrically connected, the communication module is electrically connected to the core computing module through a relay, and wirelessly connected to the host computer, and the data storage module realizes data interaction with the host computer. The invention realizes the automatic monitoring of the operation state data of medium and large transformers, the monitoring data is complete and accurate, and the data content is specially aimed at the service of on-site maintenance personnel. At the same time, it solves the relevant requirements for the confidentiality of transformer operation data existing in data acquisition.

Description

technical field [0001] The invention belongs to the technical field of transformer operation state monitoring, and in particular relates to a transformer operation state monitoring terminal and a monitoring method. Background technique [0002] As the hub of the power grid, the safe operation of transformers has always been an important part of people's livelihood. When there is a problem with the operation of the transformer, the efficiency of emergency repair and the time spent on normal maintenance will greatly affect the strength and reliability of the power grid. [0003] With the sharp increase in power consumption and the higher and higher requirements for power supply quality of many devices, this requires that the speed of troubleshooting must be further improved. At present, when inspecting transformers, experienced maintenance personnel often use the method of venting the transformer oil to enter the interior for inspection, and even need to pull it back to the m...
