Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, and in particular relates to a wireless probe-type temperature measuring sensor. Background Art

[0002] When the power equipment is working, each component will generate heat during operation, but the normal heating of each component cannot exceed its maximum allowable temperature to ensure the normal operation of each component. Therefore, there is an urgent need for a wireless temperature measurement sensor that can be used for power equipment.

[0003] High-voltage power transmission is increasingly used in real life, so it is more important to monitor the real-time status of transmission line operation. In real life, traditional wire monitoring methods are often affected by geographical location and surrounding environment, and cannot perform real-time and accurate temperature monitoring and early warning, resulting in immeasurable losses during the power transmission process. Based on this, real-time monitoring of high-voltage lines has been increasingly introduced into the topic of research institutions. With the continuous advancement of temperature measurement technology, especially the emergence of high-precision and long-life sensors, temperature measurement has become easier. Once the temperature of a high-voltage transmission line is too high and the wire is melted, it will cause power outages in the downstream area of ​​the wire, and will also affect upstream equipment, and may even cause fires due to the melting, which is not visible to the naked eye. Usually, when a fault occurs, the line patrol personnel need to hold the indicating device to check point by point, and its real-time nature cannot be solved. Especially when the line is too long, the entire inspection will be time-consuming and labor-intensive. Due to the complexity of the power grid work, if the large equipment of upstream and downstream users is started in an instant during the inspection, it will cause the indicating device to malfunction, which will affect the overall reliability.
