Jul 09, 2024Is the split core transformer good? What are the disadvantages of the split core current transformer?
What is the split core transformer? Is the split core transformer good? The split core current transformer is suitable for indoor devices with a rated voltage of 10kV and below. It is used for circuit control, measurement, line transformation measurement and protection. So what are the disadvantages of the split core current transformer? The link of the induction current in the split core transformer is disconnected, that is, the induction core is not a closed whole, and the magnetic circuit efficiency is reduced at the gap. It is difficult to make a complete fit after the opening, so there will be a certain impact on the induction effect and accuracy.
Is the split core transformer good?
The split core current transformer is suitable for indoor devices with a rated voltage of 10kV and below. It is used for circuit control, measurement, line transformation measurement and protection.
Structure introduction of split core current transformer
This current transformer adopts a high-strength PVC shell and a fully cast busbar structure. The transformer is directly stuck on the cable. Three elastic rubber rings are against the cable and the cable is integrated. The transformer core is made of high-quality silicon steel sheets, and the secondary wire is evenly wound on the core. The transformer is an split core structure and can be installed without cutting the cable.
Application scope of split core current transformer
1. The altitude of the installation site does not exceed 3000m;
2. Ambient temperature: -25—+40℃;
3. The outer diameter of the primary cable that can be worn: φ8—φ240mm
4. Input: 0~60KA
5. Output: 0~500mA 1A or 5A 5VDC or 4~20MA (customer-defined)
There is no pollution, corrosive and explosive media in the atmosphere that seriously affect the insulation performance of the transformer.
What are the disadvantages of split core current transformers
1. The working noise is relatively loud
2. The heat is relatively large
3. The measurement error is relatively large
4. The price is high
The link of the induction current in the split core transformer is disconnected, that is, the induction core is not a closed whole, and the efficiency of the magnetic circuit is reduced at the gap. It is difficult to make it fit perfectly after opening, so it will have a certain impact on the sensing effect and accuracy.
