Open-close current transformer is often used in equipment. It has a good induction effect, can improve the operation efficiency of the equipment, has a good effect in controlling current, and completes up and down voltage conversion. In order to make it work smoothly and avoid vibration, how should we repair it?

　　 1. Fix with positioning screws: the fixing screws are locked by two positioning screws with a 90° gap. In the traditional fixing method, the front end of the screw contacts the shaft, which may cause damage to the shaft or make it difficult to disassemble.

　　2. Fix with clamping screws: apply the tightening force of hexagon socket bolts, the gap shrinks, and the opening and closing current transformer shaft is clamped. This method is easy to fix and disassemble, and will not damage the shaft.

　　3. Keyway fixing: suitable for high torque transmission. In order to avoid axial sliding, it is usually used separately from positioning screw fixing and clamping screw fixing.

　　4.D hole fixation: If the motor shaft is D-shaped, and if the fixing screws cannot be fixed, the hole-opening current transformer can be processed into D holes corresponding to the size of the motor shaft and fixed with fixing screws, so there is no need to worry about slipping.

　　 5. Fixing of the shrink sleeve: Tighten the four positioning screws on the end face to compress the accounting sleeve, which is suitable for connecting and fixing some large torque stepper motors and servo motors.

　　 Ordinary open-close current transformers can switch sensitively between high voltage and low voltage, so that the device can switch back and forth under different voltages. They are good transformers in terms of maintaining equipment and user safety. It is mainly fixed through these methods.
