Technical Field
[0001] The utility model belongs to the technical field of high - voltage electrical appliances in power systems, and relates to a temperature and humidity monitoring device for lightning arresters. Background Technique
[0002] In a power system, a lightning arrester is an important electrical device used to protect other devices from the harm of lightning over - voltage. However, during the operation of a lightning arrester, the changes in its internal temperature and humidity will directly affect its performance and service life. Therefore, real - time monitoring of the internal temperature and humidity of a lightning arrester is of great significance for ensuring its safe operation.
[0003] Traditional methods for monitoring the temperature and humidity of lightning arresters usually rely on manual inspections or indirect monitoring by external devices, and these methods have many deficiencies. First of all, manual inspections are not only inefficient but also difficult to grasp the real - time changes in the temperature and humidity inside the lightning arrester. Secondly, although indirect monitoring by external devices can achieve real - time monitoring, due to the limitations of the sensor installation position, it often cannot accurately reflect the true temperature and humidity conditions inside the lightning arrester.
[0004] To solve the above problems, some new types of lightning arrester temperature and humidity monitoring devices have emerged in recent years. These devices achieve real - time monitoring of the internal temperature and humidity of lightning arresters by installing sensors inside or outside the lightning arrester. However, the installation positions of these sensors are not ideal enough, resulting in some deficiencies in monitoring accuracy. Summary of the Utility Model
