| titleOfInvention | Non-contact double-core cable current measuring method and device |
| abstract | The application relates to a non-contact double-core cable current measuring method, a non-contact double-core cable current measuring device, computer equipment and a storage medium. The method comprises the following steps: determining position rings of the four magnetic resistance sensor chips, acquiring the radius R of the position rings, the distance x from any one of the measuring wires to the circle center of the position rings and the magnetic induction measured values of the four magnetic resistance sensor chips according to the position rings, and acquiring the final value B of the magnetic induction measured values according to the magnetic induction measured values 1 、B 2 、B 3 、B 4 According toRadius R of the position ring, distance x from any one of the measuring conductors to the center of the position ring, and final value B of the magnetic induction measured value 1 、B 2 、B 3 、B 4 Obtaining a rotation angle theta of the two core wires 1 According to the rotation angle theta of the two-core wire 1 And obtaining the current I of the double-core cable. By adopting the method, the current sensor based on the magnetoresistive sensor chip can measure the current of the double-core cable at any rotation angle of the double-core wire. |
