Abstract

The invention discloses an energy supplying system of power line temperature measuring equipment. The energy supplying system comprises a laser emitting module, an optical fiber, a photoelectric conversion module and a power supply management module. The laser emitting module emits laser and transmits the laser to the photoelectric conversion module through the optical fiber. The photoelectric conversion module converts optical energy of the laser to electric energy and supplies the electric energy to a working circuit of the power line temperature measuring equipment after voltage boosting and stabilizing of the power supply management module. The working characteristic of the laser emitting module can ensure stable output optical power on the condition of a certain temperature, and therefore relatively stable of power supply output power after conversion by the photoelectric conversion module is realized. Furthermore complexity and cost of a power supply system are reduced, and reliability of the power supply system is improved. Furthermore the energy supplying system settles a problem of acquiring electric power from the high-voltage side of the DC power transmission line by the temperature measuring equipment.

Description

technical field [0001] The invention relates to the technical field of electric power systems, and more specifically, relates to an energy supply system for power line temperature measuring equipment. Background technique [0002] The connection points of many high-voltage electrical equipment in power plants and substations are weak links in power transmission, and they are prone to heat during long-term operation of the equipment. With the increase of re-checking, the connection point will heat up and form a vicious circle, that is, temperature rise, expansion, oxidation, contact resistance increase, and temperature rise at a certain degree, which will eventually lead to fire accidents and power supply interruptions, causing serious damage to the national economy and personnel safety. huge loss. Therefore, it is necessary to monitor the temperature of the connection point, and to send an alarm when the temperature exceeds the threshold. [0003] Existing temperature meas...
