Abstract

The invention provides a two-point detection method and device based on a wire magnetic field. The method comprises the steps of: obtaining magnetic induction intensity measurement data of magnetic sensing elements corresponding to a first measurement point and a second measurement point, wherein the straight line where the first measurement point and the second measurement point intersects or quasi-intersects with the center line of a wire, and the distance between the first measurement point and the second measurement point is known; and determining a wire current parameter by using the magnetic induction intensity measurement data, or judging whether the installation of the magnetic sensing element is loosened or not. Installation is convenient, an anti-interference capability is strong, and the device can be used for wire current detection and installation loosening detection.

Description

technical field [0001] The invention relates to the field of smart grids, in particular to a two-point detection method and device based on a wire magnetic field. Background technique [0002] Smart grid requires real-time detection of key electrical and environmental parameters to ensure efficient and reliable operation of the grid. The current detection of the transmission line is a basic content of the power grid detection. The vibration or galloping detection of the transmission line is also an important item to ensure the normal operation of the power grid. How to realize the The current detection of the transmission line, the vibration detection of the transmission line, and the economic and rapid deployment of the detection device are still a problem that needs further research. [0003] Using magnetic and electric fields to locate transmission lines, or to measure transmission line currents, is the basic technical approach adopted in the electric power field. From t...
