Non-contact power supply system of power monitoring equipment

Abstract

The invention belongs to the technical field of wireless power supply and relates to a non-contact power supply system of power monitoring equipment. The system comprises an induction power taking device, a wireless electric energy transmission emitting device, an insulator string and a wireless electric energy transmission receiving device. According to the non-contact power supply system of the power monitoring equipment of the invention, the insulator string is used as a high-voltage isolation component for wireless power transmission and can fix an intermediate coil, so that double functions are achieved, the cost is saved, and the size of the system is reduced; a multi-stage relay coil is used for wireless transmission of electric energy, based on the size of insulators, and the insulators are used as a non-contact channel for wireless energy transmission between the induction power taking device and the power monitoring equipment, so that the size and the weight of the whole device are reduced, and energy can be transmitted while high-voltage isolation is realized. Compared with a microwave transmission mode, the system is safer and smaller in size.

Description

technical field [0001] The invention relates to the technical field of wireless power supply, in particular to a non-contact power supply system for power monitoring equipment. Background technique [0002] At present, with the rapid development of China's electric power industry, the safe operation of the power system is becoming more and more important. The long-distance ultra-high voltage transmission method is the main artery of the power system, and its operation safety directly determines the safety and efficiency of the power system. In order to make the power grid gradually Moving towards automation and intelligence requires a large number of monitoring equipment and sensors. There are mainly three traditional processing methods at home and abroad: one is solar power supply. As a renewable clean energy, the power supply quality of this method is vulnerable to weather Moreover, the life of the battery is related to the number of charge and discharge cycles. The theore...

Chinese patent CN112491167B-Microwave wireless power supply system and method applied to power grid transmission line monitoring equipment uses microwaves to transmit power. It is an online monitoring device on high-voltage transmission lines, but microwaves are used to transmit energy. Although the transmission efficiency is very high, but When transmitting high-power electric energy, there are high requirements for antenna equipment.

[0004] Therefore, it has limitations on the transmission power; in addition, due to the strong radiation loss of microwaves and lasers, it is not suitable for charging electronic devices

Moreover, the Chinese patent CN112491167B-microwave wireless power supply system and method applied to power grid transmission line monitoring equipment does not set a high-voltage isolation scheme, and the safety is not high
