Transformer DC Bias Monitoring Device

Abstract

The invention provides a transformer DC bias monitoring device, including a sensor monitoring device and a data processing center, the sensor monitoring device is used to collect the DC bias magnetic monitoring data of the transformer and send it to the data processing center, and the data processing center is used to receive and process The DC bias monitoring data sent by the sensor monitoring device; the sensor monitoring device includes nodes that are networked in a multi-hop manner through a wireless sensor network, and the nodes include sensor nodes and base station nodes, wherein the sensor nodes are used to collect the DC voltage of the transformer Bias magnetic monitoring data; the base station node communicates with the data processing center through the communication network to gather the DC bias magnetic monitoring data collected by the sensor nodes and transmit them to the data processing center. The invention realizes the real-time monitoring of the DC bias magnetic condition of the transformer.

Description

technical field [0001] The invention relates to the field of transformer monitoring, in particular to a transformer DC bias monitoring device. Background technique [0002] In recent years, as more and more direct current transmission lines have been put into operation, the problem of the impact of direct current transmission on AC transformers under the single-pole ground circuit and bipolar unbalanced operation mode has become increasingly prominent: it will cause the transformer vibration and noise to increase significantly, Problems such as iron core heating and resonance affect the life of the transformer and safe production. It has become the consensus of more and more experts and scholars to monitor the DC bias condition of the transformer so as to solve its influence on the transformer. Contents of the invention [0003] In view of the above problems, the present invention provides a transformer DC bias monitoring device. [0004] The object of the present invent...
