Q1:Â What is a split-core current transformer?
A1:Â Split core current transformer is made of high strength PVC shell, fully cast busbar type structure. a split core current transformer is directly stuck on the cable with three sexual rubber rings against the cable and the cable one. The transformer core uses better silicon steel rolled, the secondary wire evenly wound in the core. Transformers for the open and closed structures can be installed without cutting the cable.
Q2:Â What is the meaning of the circles of the split core current transformer?
A2:Â On electrical system diagrams, a small circle is often used to represent a winding, and a circle is used to represent a winding. If you have two circles in a series, that means that the open and closed current transformer has two windings. If you have three circles in a series, that means you have three windings.
Q3:Â What is a split core current transformer error?
A3:Â Due to the structure of the split core current transformer core and material properties, the current transformer has an excitation current I0, which makes it produces errors.
Tips:Â How to fix the split core current transformer?
The split core current sensor is a good transformer to protect the equipment and the user's safety.
- Fixing with clamping screws. The shaft of the split core current transformer is clamped by using the tightening force of the hexagonal recessed head bolt to reduce the gap. This method is easy to install and disassemble without causing damage to the shaft.
- Keyway fixing. To prevent axial slippage, a combination of set screw fixing and clamping screw fixing is usually used. This fixing method is suitable for high-torque drives.
- Expansion sleeve fixing. Tightening the four set screws on the end face, this method is suitable for the connection and fixing of some high-torque stepper motors and servo motors.
