Embodiment Construction

[0042] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0043] Cabinet equipment such as power distribution cabinets, ring network cabinets, and switch cabinets are widely used in power systems. Flat copper bars are generally used as conductive conductors in these cabinet devices. The current on these copper bars is a must in the power system. One of the important parameters to be measured can reflect the operating state of the power system and is an indispensable input variable for the optimal operation, control and protection of the power system. Therefore, it is very important to measure the current on the copper conduct...

Abstract

The present application relates to a flat conductor current measurement method, device, computer equipment and storage medium. The method includes: acquiring the magnetic induction intensity generated by each uniaxial magnetic sensor in a preset number of uniaxial magnetic sensors in the direction of magnetic sensitivity; wherein the preset number includes at least 3; The magnetic induction intensity generated in the direction of magnetic sensitivity determines the current of the measured flat conductor; wherein, a preset number of uniaxial magnetic sensors are arranged in a straight line in space, and the straight line is perpendicular to the length direction of the measured flat conductor and is connected to the measured flat conductor. The flat faces of the conductors are parallel. Since each single-axis magnetic sensor only needs to meet the installation requirements that a preset number of single-axis magnetic sensors are arranged along a straight line in space, the straight line is perpendicular to the length direction of the measured flat conductor and parallel to the flat surface of the measured flat conductor.

Description

technical field [0001] The present application relates to the field of measurement technology, and in particular, to a flat conductor current measurement method, device, computer equipment and storage medium. Background technique [0002] Cabinet equipment such as power distribution cabinets, ring network cabinets, and switch cabinets are widely used in power systems. Flat copper bars are generally used as conductive conductors in these cabinet devices. The current on these copper bars is a must in the power system. One of the important parameters to be measured can reflect the operating state of the power system, and is an indispensable input variable for the power system's optimal operation, control, and protection functions. Therefore, it is very important to measure the current on the copper conductor, and the measurement accuracy and response speed should meet the requirements of different functions of the power system. [0003] In recent years, with the development of...
