[0002] The three-phase mutual inductor is a device that can measure the current and voltage on the transmission line in real time. The three-phase mutual inductor needs to be tested after production and assembly. The three-phase mutual inductor is tested before leaving the factory by connecting the current in the ring. The equipment used is a commercially available multi-station mutual inductor comprehensive testing device. The personnel put the three-phase mutual inductor set flat on the terminal post, and then start the cylinder to connect another terminal with the terminal post to connect the current. The current and voltage of the mutual inductor can be detected through the existing detection system. However, the equipment requires personnel to manually put the assembled mutual inductor on the terminal post, and then manually remove it after the test is completed. The placing and taking action greatly reduces the efficiency of material feeding detection and cannot meet production needs. Utility Model Content
