一种输电线路大功率取能电源的设计
A design of high-power supply installed on transmission lines
摘要
Abstract
According to the transformer principle, the paper designs a kind of self-power supply, which can be directly installed on the transmission lines and output is 12 V/20 W. When current flows in the transmission lines, a special induction coil senses voltage, and then, through the rectifier, filter, outputs power to supply load. In order to effectively resist the sharp waves, an impact protection is installed, and the voltage feedback protection circuit and energy protection circuit are used to take full advantage of the efficiency of the coil. On this basis, the whole circuit is built. Simulating the normal operating in the physical platform of transmission lines for the test of long time, high current impacts at short time (0.5 s) on the fault situation and impacted by lightning and recording data, data show that the self-power supply works well in the simulation platform, reduces the harm of saturation of the core flux effectively, and outputs 12 V/20 W stably. The self-power supply has the advantage of small size, low cost, high output power, high stability, and is easy to install with snap-in structure, which can meet the high voltage monitoring equipment for power supply requirements very well.关键词
