AC/DC Test Transformer
Darui Electric recommends for you:
The TQSB series oil-immersed test transformer is produced based on the "Test Transformer" standard of the Ministry of Machinery and Electronics, with significant improvements over the original similar products. The TQSB (JZ) series lightweight AC/DC high-voltage test transformer is a new type of product produced based on the TQSBJ series test transformer, in accordance with the national standard "JB∕T 9641-1999" after improvements. It is particularly suitable for insulation strength testing under power frequency or DC high voltage for various high-voltage electrical equipment, electrical components, and insulating materials in power systems, industrial and mining enterprises, and scientific research departments. It is an indispensable important equipment in high-voltage testing.

AC/DC Test Transformer Features:
1. The iron core of this series of products is a single-phase core type, made of high-quality cold-rolled oriented silicon steel sheets stacked, with steel as the clamping material.
2. The high-voltage coil is a cylindrical multi-layer tower type, wound with high-quality polyester enameled wire and insulation materials with high withstand voltage.
3. The low-voltage coil is on the outside, and the instrument coil is an independent winding, generally 100V.
4. The shell is octagonal, and test transformers above 10kVA are equipped with movable iron wheels. It has the characteristics of light weight, small size, easy movement, and superior performance.
5. The TQSB series oil-immersed test transformer is a single-phase transformer, using power frequency 220V or 380V power supply connected to the operation box (console), and the output voltage is adjusted to 0-200V or 0-400V through the autotransformer inside the operation box, which is then output to the primary winding of the test transformer. According to the principle of electromagnetic induction, the required high voltage for testing can be obtained in the high-voltage winding of the test transformer.
6. This series of products has the characteristics of small size, light weight, compact structure, complete functions, strong universality, and convenient use.
