Design the electric energy meter constant magnetic field verification device system, carry out the constant magnetic field verification, and realize the electric energy meter constant magnetic field automatic verification. To ensure the accuracy and traceability of the magnetic field, a magnetic field sensor is installed at the bottom of the tray, and the test magnetic field is read in real time through the magnetic field sensor. The device is fixedly connected with an infrared sensor to detect the rotation angle of the magnetic steel. The operation of the three-axis motor of the magnetic field detection device changes the position of the magnetic steel around the bottom and top of the electric energy meter to complete the verification of the entire electric meter. The electric energy meter constant magnetic field verification device has high accuracy, strong safety, and can complete the automatic detection function.
