Problems solved by technology

[0003] At present, most of the existing current measurement devices are single magnetic field sensors. In the actual measurement process, due to various non-ideal conditions, such as wire eccentricity, magnetic field sensor noise, nearby wire interference, etc., there will be excessive current measurement errors. Problems that seriously affect the accuracy and precision of the current measurement of the conductor

Abstract

The invention provides a circular sensor array for measuring current, which comprises a circular-ring-shaped PCB. N magnetic field sensors are uniformly arranged on the circular-ring-shaped PCB, n is an integer greater than or equal to 2, and the n magnetic field sensors form the circular sensor array. When the circular sensor array is used for measuring current, a conductor of which the current value is to be measured is arranged at the center of the circular-ring-shaped PCB, namely the center of the circular sensor array for detection, so that measurement errors caused by conditions such as wire eccentricity, sensor noise and nearby wire interference can be greatly weakened.

Description

technical field [0001] The invention relates to the technical field of current measurement, in particular to a circular sensor array for measuring current. Background technique [0002] Current (current intensity) is the amount of electricity passing through any section of a conductor per unit time, in units of ampere (A), usually represented by the letter I. The current is invisible and intangible. The intensity of the current needs to be measured by the current measuring device. The existing electric quantity measuring device is equipped with a magnetic field sensor. The magnetic field sensor can convert various magnetic fields and their changing quantities into electrical signals and output, so as to realize the measurement of the current intensity of the conductor. [0003] At present, most of the existing current measurement devices are single magnetic field sensors. In the actual measurement process, due to various non-ideal conditions, such as wire eccentricity, magn...
