Abstract

The invention provides an induction power taking device of a non-closed type magnetic core, which comprises a non-closed type drawable magnetic core coil assembly and an electric energy management module connected with the drawable magnetic core coil assembly, and is characterized in that the drawable magnetic core coil assembly comprises a plurality of thin column type magnetic cores and a magnetic core coil arranged on the outer sides of all the thin column type magnetic cores in a sleeving manner; at least a portion of the fine cylindrical core is drawable with respect to the core coil. The non-closed type magnetic core is adopted in the induction power taking device of the non-closed type magnetic core, the problem that different voltage classes of the induction power taking device are matched and compatible with the cable diameter is solved, meanwhile, a traditional whole magnetic core is equivalently replaced by several thin magnetic cores with higher effective magnetic conductivity, the magnetic cores can be drawn to change the length of a magnetic circuit in the magnetic cores, and therefore the magnetic core can be replaced by the thin magnetic cores with higher effective magnetic conductivity. And the output power and the power density of the whole magnetic core can be improved.

Description

technical field

[0001] The invention belongs to the technical field of inductive power taking, and more particularly, relates to an inductive power taking device with a non-closed magnetic core. Background technique

[0002] At present, with the proposal of the dual carbon goal, the development of a new power system with intelligent sensing capability is a key link, and a large number of wireless sensors are the key to achieving "comprehensive sensing and interconnection". The power supply problem of the power sensor is the core module that restricts its large-scale application. The methods of power supply for online power monitoring sensors mainly include battery power supply, solar power supply, laser power supply, resonant coupling power supply, vibration power supply, capacitive partial voltage power supply, magnetic field induction power supply, etc. Inductive power supply is due to its stability and stability. Maturity is the most widely used.

[0003] At present, fo...
