Abstract

The invention discloses a high voltage line temperature sensor comprising a temperature measurement module used for sensing a temperature signal and converting the temperature signal into an electric signal, a single-chip microcomputer connected with the temperature measurement module and used for controlling a lighting device to illuminate according to the electric single, and a fiber arranged on the lighting device and used for receiving an optical signal from the lighting device; the fiber is connected with a host fiber port so as to transmit the optical signal to the host; the temperature sensor can timely determine whether the cable has faults or not, and workers can fast determine a line fault section according to local alarm conditions, thus finding the fault points; in addition, the fiber can transmit the collected signals, thus realizing optoelectronic isolations, and effectively solving the insulation problems; the energy loss in a signal transmission process is small, and the signal transmission is not affected by external environments.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a temperature sensor for high-voltage lines. Background technique [0002] In the ring network power distribution system, especially in the system that uses a large number of ring network load switches, if a short-circuit fault or a ground fault occurs in the lower-level power distribution network system, the upper-level power supply system must be within the specified Time to break, in order to prevent major accidents. Before a fault occurs, the temperature of the high-voltage line will often be too high in a short period of time. Therefore, it is of great research significance for those skilled in the art to promptly remind the operating status of the line by detecting the temperature change. [0003] In the prior art, although temperature sensors are relatively mature, most of them are not suitable for use in high-voltage lines, and the collected temperature signals...
