[0002] With the rapid development of my country's economy, the living standards of Chinese people are also constantly improving. The most used electrical equipment is the current transformer. The current transformer is an instrument that converts the large current on the primary side into the small current on the secondary side for measurement based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. Its primary winding has very few turns and is connected in series in the circuit of the current to be measured. When fixing the current transformer, a current transformer connection device is used. When the existing current transformer is connected and installed, a horizontal plate is installed at the bottom of the current transformer. The horizontal plate has a through hole and is attached to the external connection. Since the position of the horizontal plate cannot be adjusted, it is not convenient for the current transformer to be installed at corners. To this end, we propose a current transformer connection device. Utility Model Content
