基于振动、噪声和中性点电流的变压器直流偏磁监测系统
摘要：
本发明涉及一种基于振动、噪声和中性点电流的变压器直流偏磁监测系统，包括直流偏磁控制柜、振动传感器、噪声传感器、中心点电流传感器、通信网络和后台服务器，所述的直流偏磁控制柜一端分别与振动传感器、噪声传感器、中心点电流传感器连接，所述的直流偏磁控制柜另一端通过通信网络和后台服务器连接。与现有技术相比，本发明具有可以实时掌握变压器中性点直流以及噪声、振动数据，防止变压器在危险状态下运行等优点。
摘要（英）：

The invention relates to a transformer direct current magnetic bias monitoring system based on vibration, noise and neutral point current. The system includes a direct current magnetic bias control cabinet, a vibration sensor, a noise sensor a central point current sensor, a communication network and a background server, one end of the direct current magnetic bias control cabinet is connected with the vibration sensor, the noise sensor and the central point current sensor, and the other end of the direct current magnetic bias control cabinet is connected with the background server through the communication network. Compared with the prior art, the transformer direct current magnetic bias monitoring system based on vibration, noise and neutral point current has the advantage that neutral point direct current and noise and vibration data of a transformer can be mastered in real time, thereby preventing the transformer from running in a dangerous state.
