As the core component of the power system, the operational stability of the transformer is crucial. However, due to the fact that some parts of the insulation structure may be subjected to excessive electric field strength, the phenomenon of partial discharge may occur. These discharges can not only trigger the deterioration of the oil-paper insulation, but can also further lead to transformer failure. In order to effectively monitor and prevent these potential problems, the UHF transformer partial discharge monitoring device came into being.
Technical Features & Benefits:
UHF monitoring: Compared with the traditional pulsed current method, the UHF method has a higher frequency response and a wider frequency band, which can more accurately capture the signal of partial discharge.
Real-time monitoring: Through the ultra-high frequency sensor installed on the transformer, the device can monitor the partial discharge phenomenon inside the transformer in real time to ensure the safe and stable operation of the transformer.
Rich data display: The device provides a variety of data display functions, such as the cumulative graph of partial amplitude and partial discharge data display, etc., to help users fully understand the operating status of the transformer.
High-precision time synchronization: In the case of optical fiber as the communication medium, the system synchronizes through optical synchronization signals to ensure the accuracy and consistency of data acquisition.
Powerful data processing capabilities: High-performance FPGA processors are used to achieve high-speed sampling, storage and analysis to ensure the real-time and accuracy of data.
Flexible data access mode: The device supports serial port or network access to the integrated processing unit in the substation, which is convenient for integration with other systems.
Accurate positioning ability: The double-ended positioning measurement method can realize real-time positioning of the partial discharge generated by the cable body, which provides strong support for troubleshooting.
Fields of application. The UHF transformer partial discharge monitoring device is especially suitable for transformers with voltage levels of 110kV and above. It is widely used in the power system, which provides a strong guarantee for the safe operation of the transformer.
Summary. With its advanced technology and rich functions, the UHF transformer partial discharge monitoring device provides strong support for the stable operation of the power system. Through real-time monitoring and analysis of partial discharge phenomena, the device can detect potential problems in time and take corresponding measures to ensure the safe operation of the transformer. With the continuous advancement of technology and the expansion of application fields, the device will play a more important role in the power system.
