Transformer Neutral Point DC Bias Monitoring System
Category: Product Center
Key words: equipment
Product Description
On-line monitoring of DC magnetic bias at the neutral point of the transformer can monitor the noise and vibration of the neutral point of the transformer and the transformer body in real time, so as to realize real-time monitoring of the operation status of the transformer equipment. At the same time, potential faults of the transformer can be found in time by analyzing the monitoring data and provide important data basis for condition-based maintenance. Once the DC at the neutral point of the transformer or the vibration of the transformer body exceeds the standard, the standard, the operator can take timely measures, to prevent major accidents of transformers and systems, it provides a strong and reliable guarantee for the safe, reliable, stable and economical operation of the power system.
system composition
The transformer neutral point DC bias online monitoring system is mainly composed of: current sensor, vibration sensor, noise sensor, neutral point DC bias monitoring device, monitoring IED, etc. The monitoring device collects the data of the front-end sensor and uploads it to the monitoring IED through RS485, and the monitoring IED is uploaded to the station-end monitoring system through 61850.
Functional features
◎Real-time monitoring of AC and DC data of transformer neutral point and noise and vibration data of transformer body;
◎The use of core-type high-precision transformer, high measurement accuracy;
◎The installation is simple and convenient, and can be installed with electricity without power failure of the main equipment;
◎It has the functions of automatic state parameter acquisition, signal conditioning, analog-to-digital conversion, data preprocessing and transmission to the upper unit;
◎Support RS485 and 61850 and other communication methods;
◎The parameters are digitized and cached locally, and the monitoring data is regularly sent to the online monitoring IED host or station for monitoring.
* Note: Please be sure to fill in the information accurately and keep the communication unblocked. We will get in touch with you as soon as possible.
