Abstract:

This paper proposes a design proposal which combines the electric power obtained from the high side with thermal batteries by using the specially designed coil.It also introduces the principle and main design of this program.The result shows that it can provides stable power in case of normal current of the busbar and even shorted fault or broken fault.It can reliably protect other circuits in case of large current and provide a stable voltage output,and thus it effectively solves the problem about the power source of electronic equipments which are used in overhead transmission lines.

Key words: attain the energy from the buses;power supply;power control;triac
