Temperature rise monitoring device of power transmission line node based on induction electricity taking

Abstract

The invention discloses a temperature rise monitoring device of a power transmission line node based on induction electricity taking. The temperature rise monitoring device comprises a signal transceiving unit and an energy supply unit, which are integrated in a closed sealing cover; the energy supply unit comprises an induction electricity taking module, an electric energy adaption module and anenergy storage module; the induction electricity taking module is used for obtaining electric energy from a circuit wire; the electric energy adaption module is connected between the induction electricity taking module and the energy storage module, and an output end of the electric energy adaption module is connected to the signal transceiving unit for performing voltage stabilization on the electric energy obtained by the induction electricity taking module and allocating the electric energy to the signal transceiving unit and the energy storage module; and the energy storage module is a super capacitor. According to thetemperature rise monitoring device disclosed by the invention, by changing a temperature collection device, a battery is replaced by the super capacitor, live installation work is performed based on the induction electricity taking technology, and the problem of short service life of the battery power supply is solved; and the problem that a power supply monitoring device singly using the induction electricity taking technology cannot work normally in the case that the current of the wire is relatively small is solved.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a device for monitoring temperature rise of transmission line nodes based on inductive power acquisition. Background technique [0002] In recent years, with the continuous growth of the national economy, urban and rural electricity consumption has increased sharply. During the peak period of electricity consumption, the phenomenon that the line power supply load operates near the limit or exceeds the limit occurs from time to time. With the high-load operation of lines becoming more and more common, the excessively high temperature of the connection joints of transmission line wires has become the "death spot" for safe operation of lines. [0003] When the connection point is operated at high temperature, it will be annealed and aged slowly, causing its strength to lose. The strength loss increases with the increase of the clamp temperature and time, and intermittent...

Problems solved by technology

[0007] The purpose of the present invention is to provide a transmission line node temperature rise monitoring device based on inductive power acquisition. By changing the temperature acquisition device and replacing the battery with a super capacitor, the live installation work can be achieved based on the inductive power acquisition technology, which solves the problem of using a battery to supply temperature. The problem of short life of the monitoring device; solves the problem that the monitoring device cannot work normally when the wire current is small by using the induction power technology alone
