TQSB series oil-immersed test transformer
TQSB series oil-immersed test transformer is produced according to the "Test Transformer" standard of the Electromechanical Department after extensive improvements on the basis of the original similar products. The TQSB series of light AC and DC high voltage test transformers is based on the YDJ series of test transformers in accordance with national standards " JB∕T 9641-1999" has been improved and produced a new type of product.
Especially suitable for power system, industrial and mining enterprises, research departments and other high voltage electrical equipment, electrical components, insulation materials under high frequency or DC high voltage insulation strength test. It is an indispensable and important equipment in high pressure test.
TQSB series oil immersed test transformer product introduction
Test transformers are divided according to insulation and cooling conditions and can be divided into oil-immersed test transformers and dry test transformers.
The oil-immersed test transformer is applicable to the insulation strength test of various electrical products, electrical equipment, and insulation materials under the specified voltage, assess the insulation level of the product, find the insulation defect of the tested product and measure the ability to withstand overvoltage. It is a basic test equipment for a large number of users, such as power stations, power supply and distribution systems, and research institutes.
TQSB Series Oil Immersed Test Transformers Features
1, the product can be divided into: AC, AC and DC, AC series excitation, AC and DC series excitation;
2. The high-voltage coil is a cylindrical multi-layer tower, which is made of high-quality polyester enameled wire and high-voltage insulation material.
3, low voltage coil outside, the instrument coil is a separate winding, under normal circumstances is 100V.
4. The shell is octagonal and the test transformer above 10 kVA is equipped with a movable iron wheel. Oil immersion is an excellent choice for test transformers, featuring light weight, small size, easy movement, and good performance stability.
5. The TQSB series oil-immersed test transformer is a single-phase transformer. It is connected to the operating box (set) with the power frequency 220V or 380V power supply, and is adjusted to 0-200V or 0-400V by the auto-connected voltage regulator in the operating box. The initial set of windings of the test transformer, according to the principle of electromagnetic induction, can be used to test the high voltage winding of the transformer to obtain the high voltage required for the test.
6, this series of products with small size, light weight, compact structure, complete functions, versatility and ease of use and so on.
