Description

technical field [0001] The invention relates to a system and method for comprehensive energy management of high-voltage transmission line monitoring equipment. Background technique [0002] In recent years, in order to detect transmission line faults in time and propose early warning schemes, various monitoring devices have been added to transmission lines to improve the stability and reliability of power transmission on transmission lines. [0003] However, these monitoring devices have put forward new power supply requirements. The traditional power supply method is often cumbersome in wiring, and it is troublesome to replace batteries in the field. At present, the power supply for these monitoring devices is only a single way of solar power generation. Solar power generation is a renewable and environmentally friendly power generation method that converts solar energy into electrical energy. It does not produce greenhouse gases such as carbon dioxide during the power gene...

Problems solved by technology

Solar cells cannot generate electricity at night, and are easily affected by climate interference and limited by their own power supply capacity, which is a great test for the normal operation of monitoring equipment

[0005] The existing way to obtain energy from high-voltage transmission lines is inductively fetching power. The form of relying on contact-type inductive power fetching to supply power to high-voltage equipment requires additional wiring to transmit power to monitoring equipment, which is not only limited in transmission distance, but also The wiring is cumbersome and cannot meet the requirements of high-voltage transmission line power supply insulation; the current way of inductive power acquisition for high-voltage transmission lines has been improved. Although wireless transmission of power is used to supply power to monitoring equipment, when the distance is long The energy is weak and limited in transmission distance

At present, the problem faced by the way of using induction power to supply power to high-voltage transmission line equipment is to meet the requirements of transmission line insulation and monitoring equipment power supply distance.
