Description

Technical Field

Background Art

[0002] The statements in this section merely provide background technical information related to the present application and do not necessarily constitute prior art.

[0003] At present, temperature sensors are more commonly used for contact measurement of overhead lines. However, for safety reasons, contact measurement requires that the temperature measuring device be installed on the overhead line in advance, or installed after the overhead line is powered off. Many overhead lines are not equipped with temperature measuring devices at the beginning of installation, and power outages in overhead lines will not only affect industrial and residential electricity consumption, but will also cause economic losses in many cases.

[0004] There are some technical means for installing temperature measuring devices with power on in the prior art, but most of them adopt the clamping method, that is, the temperature measuring device is clamped on the overhead line after being supported by an insulating rod. However, the clamping connection method is not reliable for overhead lines in uncertain environments. At the same time, the clamping interface faces upward, and when the temperature measuring device is installed on the overhead line, its force point is just above it, so there is a risk of falling. At the same time, due to its high installation position and the overhead line being energized, the temperature measuring device itself has a higher service life requirement for the power supply used for measurement. Reducing the power consumption of the measuring device will undoubtedly increase the service life of the power supply and reduce the maintenance frequency.

[0005] In view of this, it is necessary to provide a wireless temperature measuring device that can be installed under power and an installation method thereof, as well as an overhead line temperature measuring method, to solve the above technical problems. Summary of the invention
