Embodiment Construction
[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0025] In existing power transmission lines, most of the image acquisition devices are powered by solar energy or batteries. When solar power is used, the power supply time is limited, and the power supply cannot be guaranteed throughout the day. In continuous rainy weather, the solar power supply method is easily affected; and the conversion efficien...

The application discloses an image acquisition device of a power transmission line and a power supply method thereof, which are used to solve the technical problem that the existing power supply method cannot provide long-term power supply to the image acquisition device in the power transmission line. The method includes: the induction plate in the transmission line image acquisition device collects the induced charge generated by the electric field formed between the high voltage line of the transmission line and the first contact surface; receives the collected induced charge through the step-down circuit and reduces pressure processing to obtain the first electric energy and store it in the first capacitor; the first capacitor charges the second capacitor connected to the first capacitor and the storage battery so that the second capacitor can obtain the second electric energy; the second electric energy stored The second capacitor supplies power to the image acquisition device. The present application realizes reliable and long-term power supply to the image acquisition device by using the electric field through the above method, which is not affected by weather and environmental conditions, and ensures continuous and stable power supply to the image acquisition device.
Description
technical field [0001] The present application relates to the technical field of power management, and in particular to an image acquisition device of a power transmission line and a power supply method thereof. Background technique [0002] The safety of transmission lines is related to the safety of people using electricity. In recent years, more and more attention has been paid to the detection of transmission lines. Most of the detection methods are implemented using image acquisition devices. In existing power transmission lines, the image acquisition device is generally powered by solar energy or battery. [0003] However, solar power supply has a certain time limit, which cannot guarantee the power supply of the image acquisition device throughout the day. Moreover, it is very susceptible to the influence of weather and environment. In the rainy season and other seasons when there are few sunny days, the use of solar energy cannot guarantee sufficient power supply. ...
