Overview
The AC/DC test transformer adopts the iron core integral high-voltage wire wrapping technology, which has the advantages of lighter volume and higher capacity. The transformer for power frequency withstand voltage test has a single frame iron core. The coil adopts a multi-layer tower structure with the same core cylinder. The primary low-voltage winding is wound on the iron core, and the secondary high-voltage winding is wound on the outside of the low-voltage winding. This coaxial arrangement reduces the coupling loss between the windings. The outer shell of the product is made into an octagonal structure that matches well with the core, and the overall appearance is beautiful and generous
Product Details
.AC/DC test transformerThe use of iron core integral high-voltage wire wrapping technology has advantages such as lighter volume and increased capacity. The KTSBJ high-voltage test transformer is a type of high-voltage test transformer product produced based on the YDJ type high-voltage test transformer of the same type, and improved according to the national standard DL/T848.2-2004 for test transformers. Compared with similar YDJ type products, this series of products has the characteristics of small size, light weight, compact structure, and convenient transportation. It is used in power, industrial and mining, scientific research and other departments to conduct power frequency withstand voltage tests on various high-voltage electrical equipment, electrical components, and insulation materials. It is the * instrument in high-voltage testing.
working principle
The AC high voltage test transformer is a single-phase transformer with connection group number II. The working process of a single test transformer is to connect the AC 380V voltage to the power control panel, and adjust the primary winding of the high voltage test transformer from 0 to 400V voltage through the self coupling voltage regulator (attached to the regulator above 50KVA) inside the power control panel. According to the principle of electromagnetic induction, the high voltage required for the test can be obtained in the high voltage winding of the test transformer.
