Abstract: Aiming at the difficulty of electric power equipment supply on high-voltage transmission line and the defects such as high cost of solar cell, large volume, limited installation site and power instability, this paper designed the monitoring device-used power supply on high-voltage transmission line. This device was composed of induction power supply, photovoltaic power, and power select control module. The massive structure of this device was analyzed. This paper gave the key module design and the switching implement method. The experimental result shows that this power device could realize the switching between induction power supply and photovoltaic power, to provide the safe and stable, uninterrupted electric energy for the monitoring device.
Key words: transmission line; monitoring device; induction power supply; photovoltaic power; switching mode
