Abstract

The invention provides an acquisition and processing system of direct-current magnetic bias monitoring data of a region-level transformer. The system comprises a direct current magnetic bias monitoring data acquisition module, a far-end cloud platform and a remote monitoring terminal. The direct current magnetic bias monitoring data acquisition module acquires direct current magnetic bias monitoring data of transformer direct current magnetic bias transformers in each transformer station area based on a wireless sensor network, and sends the direct current magnetic bias monitoring data of thetransformer direct current magnetic bias transformers to the far-end cloud platform for storage and analysis processing. According to the invention, based on the cloud platform technology, the directcurrent magnetic bias monitoring data of the transformer direct current magnetic bias transformers are sent to the far-end cloud platform and the remote monitoring terminal acquires data of each transformer in real time from the far-end cloud platform, so commanders can timely and clearly check the direct current magnetic bias conditions of the transformers, efficiency is greatly improved and error and neglected links are reduced.

Description

technical field [0001] The invention relates to the field of DC bias magnetic monitoring of transformers, in particular to a data acquisition and processing system for DC bias magnetic monitoring of regional transformers. Background technique [0002] In recent years, EHVDC power transmission has been widely used in long-distance power transmission in my country due to its economical and efficient characteristics. The problem of the impact on the AC transformer is becoming more and more prominent. It has become the consensus of more and more scholars and experts to monitor the DC bias state of transformer and solve its influence on transformer. [0003] In related technologies, traditional measuring instruments such as DC clamp meters are used to collect DC bias test data of transformers. However, this method has great limitations, such as small calipers that cannot adapt to wider grounding bars, and data reading is not intuitive. Inconvenient data recording, poor real-time...
