Problems solved by technology

However, according to years of operation, insufficient power supply has always been the bottleneck for the stable operation of the device
[0005] At present, the power supply method usually adopted by transmission line video surveillance devices is mainly solar power supply. The power supply device is composed of solar panels and batteries, which has the advantages of convenient installation, low investment, and environmental protection. The device monitors the operation 24 hours a day, and the continuous rainy weather makes the power supply interruption affect the normal operation of the equipment
[0006] The 220V low-voltage line power supply method is also adopted. A 220V low-voltage line is connected to the distribution transformer near the tower to directly extend to the top of the tower to connect to the video device to realize power supply. Power interruption due to weather

Abstract

The invention relates to a wind-solar complementary power supply system in power transmission line video monitoring. Solar power supply adopted at present cannot meet the requirements of all-weather video monitoring of a power transmission line and continuous and stable operation in continuous cloudy and rainy days, so that dangerous spot on-site monitoring blind spots are formed. The wind-solar complementary power supply system in the power transmission line video monitoring comprises a wind driven generator (1), a solar cell module (2) and a wind-solar complementary controller (3), the wind driven generator and the solar cell module are respectively connected with the wind-solar complementary controller, and the wind-solar complementary controller is respectively connected with a storage battery pack (4), an alternating current inverter (5) and a direct current converter (6). The AC inverter is connected with an infrared camera (7), and the DC converter is connected with a camera holder (8) and a wireless MESH antenna (9). The invention is applied to the power supply field.

Description

technical field [0001] The invention relates to a wind-solar complementary power supply system in video monitoring of power transmission lines. Background technique [0002] The current solar power supply cannot meet the all-weather video surveillance of transmission lines and the requirements for continuous and stable operation in continuous rainy days, thus forming blind spots in on-site monitoring of dangerous points. The wind-solar hybrid power supply system utilizes the complementarity of wind energy and solar energy resources to realize all-weather power generation, which effectively solves this problem. [0003] With the rapid development of the economy, the construction of infrastructure such as transportation, pipelines, factories, and housing continues to accelerate. Illegal construction of tall machinery such as cranes and high-arm pump trucks in the protection area of ​​transmission lines often occurs, which has caused great harm to the safe operation of transmis...
