This design makes the test bench more stable and reliable during operation. The plug-in method generally has a stable structure and good contact performance, which can ensure stable current transmission during the test. This helps to reduce the risk of safety accidents caused by electrical failures and improve the safety of the test. The pins of the transformer coil are plugged into the socket 5 of the rotating seat 2.
