Problems solved by technology

[0003] During the operation of the capacitor, if the temperature is too high, it will increase the dielectric loss of the capacitor and reduce the dielectric breakdown strength, thereby shortening the service life of the capacitor. In severe cases, the dielectric breakdown of the capacitor may occur and cause its damage

Abstract

The invention provides an online fault monitoring device for power capacitors. Device composition ： The power capacitor temperature real-time online monitoring device is composed of a wireless digital temperature sensor (DWT), a management host and a base station (BS). The data measured by the wireless digital temperature sensor is transmitted to the base station, and the base station transmits the temperature data to the management host. The invention installs a wireless digital sensor on the capacitor, the temperature data measured is through the communication interface or the management host, and the temperature rise state of the capacitor is detected and controlled in real time through the management host. It has the advantages of convenient management, timely and accurate temperature monitoring and long-distance transmission of temperature data. It is suitable for application in the monitoring and management of the temperature of power capacitors in the electric power field.

Description

Technical field [0001] The present invention involves an electronic information field, an online monitoring device based on a wireless sensor network (WSN). Background technique [0002] In the power system, maintaining the powerless power balance under the normal operation of the power grid is the basic condition to ensure the quality of power supply.The use of power capacitors for non -contribution compensation can increase the power factor, reduce the power loss of the power grid, and also increase the capacity utilization rate of transformers and power lines, and stabilize the voltage.Therefore, the safe operation of the capacitor plays a very important role in ensuring the power supply quality and efficiency of the power system. [0003] During the operation of the capacitor, if the temperature is high, the loss of the power container medium will increase and the medium breakdown intensity will be reduced, thereby shortening the service life of the capacitor. In severe cases...
