Product Description

High voltage oil-immersed test transformer

High voltage oil-immersed test transformer, full name YDJ, TDM (G) series oil-immersed test transformer, English name: Oil-filled high-voltage test transformer. The oil-immersed high-voltage test transformer is the basic test equipment used by power plants, power supply bureaus, and scientific research units to perform AC withstand voltage tests. It has passed the standards of the National Quality Supervision Bureau and is used for insulation strength tests under specified voltages on various electrical products, electrical components, insulating materials, etc., to assess the insulation level of products, discover insulation defects of the test object, and measure the ability to withstand overvoltage.

Aliases

Oil-immersed high-voltage test transformer: oil test transformer, oil transformer, oil high-voltage test transformer, high-voltage test transformer, power high-voltage test transformer, ultra-light high-voltage test transformer, cascade high-voltage test transformer, AC/DC high-voltage test transformer, high-voltage booster, high-voltage withstand voltage machine, high-voltage withstand voltage instrument.

Structure

The core of the oil-immersed high-voltage test transformer is a single-phase core type, made of high-quality cold-rolled oriented silicon steel sheets, and fastened with steel clamps. The high-voltage coil is a cylindrical multi-layer tower type, wound with high-quality polyester enameled wire and high withstand voltage insulating materials. The low-voltage coil is on the outside, and the instrument coil is an independent winding, generally 100V. 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.

Main features: compact product structure, strong versatility, convenient use, stable performance, especially convenient for users to test the insulation performance of various electrical equipment on site. There are three types: AC, AC/DC, and AC series excitation. It adopts a unique structure of axisymmetric unequal octagonal shell; can output dual high voltage. The oil level in the oil tank is lower than the tank edge, avoiding oil leakage. The terminals are on the tank cover, avoiding collision and improving mechanical and electrical performance. It has the characteristics of compact structure, stable electrical performance, sufficient capacity, small size, light weight, and easy use and maintenance.
