Overhead power supply system for transmission lines
To meet the needs of intelligent and refined operation and maintenance of modern power grids, we have specifically developed a series of high-performance products for various online monitoring devices, communication equipment, and sensor networks of transmission lines.Overhead intelligent power supply platform。Deeply customizedIntegrated power supply solutionFor devices deployed in different sections and serving different monitoring targets, there are significant differences in their working modes, power consumption characteristics, acquisition frequencies, and communication requirements. Therefore, weSpecific information collection requirements, device power consumption characteristics and on - site installation environmentCarry out targeted design and manufacturing for the core input.
- Support power extraction from CT and solar energy, with dual-channel power input for charging the energy storage battery, and it can also supply power to the post-stage circuit.
- The solar panel protective cover is made of special glass with high light transmittance, high strength, crack resistance and yellowing resistance.
- The unique clamp - type design can adaptively install wires with a diameter of 23 mm - 4 mm. The wire - clamping grip force meets the requirement that the lateral force is greater than 50 N.
- The whole machine is designed in an elliptical shape, and the solar energy harvesting efficiency is stronger than that of the traditional shell shape.
