Description

Technical Field

[0001] The present application relates to the technical field of power system monitoring, and more specifically, to a real-time monitoring device for overvoltage in a power system. Background Art

[0002] Power system overvoltage is a common but potentially dangerous phenomenon, so real-time monitoring is critical. The following are general steps and techniques to achieve real-time monitoring of power system overvoltage:

[0003] Sensor deployment: Voltage sensors are installed at key nodes of the power system, which are usually located in substations, distribution boxes, key equipment, etc. These sensors can monitor voltage changes in real time and transmit data to the monitoring system.

[0004] Data acquisition and processing: The voltage data collected by the sensor is collected and transmitted to the data acquisition system for processing. This may involve using a communication network (such as Ethernet or a dedicated communication line) to transmit the data to a monitoring center or data center.

[0005] Real-time monitoring system: A real-time monitoring system is set up in a monitoring center or data center to receive, process and analyze voltage data. These systems usually use specialized software to display real-time changes in voltage levels and issue alarms or warnings once an overvoltage event is detected.

[0006] Through the above steps and technologies, real-time monitoring of overvoltage in the power system can be achieved, potential safety hazards can be discovered and responded to in a timely manner, and the stable operation and reliability of the power system can be ensured.

[0007] The document with prior art publication number CN212321722U provides an online monitoring device for power harmonics of an overvoltage suppression cabinet dedicated to a power grid. The device is provided with a limiting mechanism on the connecting clamp, and the limiting mechanism is retracted to further limit the connection position of the connecting clamp, so that the position of the wire head on the connecting clamp is more stable, the detection data of the monitor body is accurate and stable, and the use effect is better. In addition, through the setting of the retractable limiting mechanism, the connecting clamp can be connected to wire heads of different sizes, and its application range is wider.

[0008] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, the connecting clamp contacts the wire head for monitoring, but since the wire head will have dust and dirt on its surface during use, it is not convenient to clean the dust and dirt on the wire head before the overvoltage monitoring, thereby affecting the conductivity and the accuracy of the monitoring data.

[0009] In view of this, we propose a real-time monitoring device for overvoltage in power system. Utility Model Content

[0012] 2. Technical solution
