Abstract

The invention discloses a power transmission line joint temperature measurement device and method. The power transmission line joint temperature measurement device comprises an infrared temperature measurement module, a logical judgment module, a wireless signal module and an operator overheating information receiving end. The power transmission line joint temperature measurement method includes analog-digital conversion, singular data rejection, equal-interval data sampling and standard exceeding judgment. By the infrared online temperature measurement device for power transmission line joints, labor can be reduced, all-weather uninterrupted online measurement of the line joint temperature can be realized, and an important improvement of power transmission intellectualization is achieved.

Description

technical field [0001] The invention belongs to the technical field of on-line monitoring of the temperature of transmission line joints, and in particular relates to a temperature detection device and method for transmission line joints. Background technique [0002] The joints of transmission lines are often due to the large contact resistance of the line joints, especially in the case of unqualified transmission line joints, the resistance of equidistant wires is a thousand times or even thousands of times larger. If the line runs for a long time and flows a large current, the wire joint will heat up severely, and the temperature rise will inevitably be obvious. The long-term temperature rise of the line joints will intensify the oxidation and corrosion, resulting in further increase of the contact resistance of the line joints and higher temperature rise, forming a vicious circle. In the past, the conductivity of the wires has been greatly reduced; with the intensificat...
