摘要：
The field test device of DC charging pile combines strong and weak current, which is easy to produce electromagnetic interference, affecting the normal operation of the device and reducing the measurement accuracy. In order to suppress the electromagnetic interference in the test device, the electromagnetic crosstalk of non-parallel transmission cables is analyzed, and the crosstalk is calculated by simulation under different parameters. At the same time, the electromagnetic shielding simulation and scheme design are carried out by using ANSYS Maxwell electromagnetic field simulation software. Based on the above scheme, a modular DC charging pile test device suitable for field test is developed, which is equipped with five sub modules including power module, metering module, communication module, control module and central processing unit. The compact assembly and modular connection of the test device are realized. The design and field application are realized through the hardware structure and installation layout. The field test results show that the device has stable communication and reliable operation, and the accuracy of electrical parameter test meets the design requirements. © 2022, Electric Power Automation Equipment Press.
