Problems solved by technology

[0002] In the power grid, the status monitoring of the cable is one of the factors related to the stability of the grid, and a key factor for the stability of the cable status detection is the insufficient stability of the power supply. The main reason is that the existing power supply system The power acquisition method is single. When the power supply process has overvoltage or undervoltage problems, it cannot meet the power supply requirements of the monitoring equipment, thus affecting the stability of the cable monitoring equipment.

Abstract

The invention provides a cable monitoring equipment power supply system combining multiple energy taking modes. The cable monitoring equipment power supply system comprises a solar module, an online power supply module, a vibration energy taking module, a temperature difference power generation module, a storage battery, an auxiliary storage battery, a judgment control module, a charging and discharging management circuit I and a charging and discharging management circuit II. The output ends of the solar module, the online power supply module, the vibration energy taking module and the temperature difference power generation module are connected with the input end of the judgment control module, and the output end of the judgment control module supplies power to a load, the charging and discharging management circuit I and the charging and discharging management circuit II. The charging and discharging management circuit I is used for managing charging and discharging of the storage battery, the charging and discharging management circuit II is used for managing charging and discharging of the auxiliary storage battery, and the power supply end of the judgment control module is connected with the positive electrode of the auxiliary storage battery, so that the power supply stability of electric power detection equipment is ensured, and continuous and stable operation of power monitoring equipment is ensured.

Description

technical field [0001] The invention relates to a power supply system, in particular to a power supply system for cable monitoring equipment combined with multiple energy harvesting methods. Background technique [0002] In the power grid, the status monitoring of the cable is one of the factors related to the stability of the grid, and a key factor for the stability of the cable status detection is the insufficient stability of the power supply. The main reason is that the existing power supply system The power acquisition method is single. When the power supply process has overvoltage and undervoltage problems, it cannot meet the power supply requirements of the monitoring equipment, thereby affecting the stability of the cable monitoring equipment. [0003] Therefore, in order to solve the above technical problems, a new technical means is continuously proposed. Contents of the invention [0004] In view of this, the object of the present invention is to provide a powe...
