The continuous development of sensor technology enables the increasing demand of monitoring parameters of electrical equipment to be met, and the construction of an intelligent sensing network greatly reduces the cost of manpower, material resources and financial resources for daily maintenance. However, due to the operational particularity of the power equipment, the power supply problem of the intelligent sensor is not solved well. Environmental restrictions such as wiring incapability, high-voltage interference, high battery replacement cost and the like cause that an intelligent sensor in the power equipment online monitoring system cannot adopt a conventional traditional power supply idea.
