The oil-immersed power transformer is made of single-phase core core, which is stacked with high-quality cold-rolled silicon steel sheets, and steel is used as a clamp for the tightening method. The high-voltage coil is a double-layer vertical barrel, which is wound by high-quality polyester enameled wire and high-voltage insulation materials. The low-voltage coil is outside, and the instrument coil is a single winding, which is generally 100V. The shell is octagonal, and the experimental transformer above 10KVA is equipped with movable iron wheels.

Benefits:

1. At the edge structure level of oil-immersed power transformer, according to the principle of “spacing utility” of transformer oil, multi-layer insulation is selected to divide the inner insulation in the transformer into multiple oil channels, so as to improve the insulation level and reduce the volume.

2. The oil-immersed power transformer solves the problem of leakage oil of TDM series transformer, because TDM series transformer has no oil reservoir, so when the temperature is too high, the oil leaks out from the oil nozzle after expansion, and this series of products sets the oil inlet at the top of the casing, and the oil in the casing is interconnected with the oil in the body. Therefore, the casing is equipped with a silicon stack. In addition to functions such as short-circuit rods and string excitation rods, they are also equivalent to transformer oil reservoirs.

3. The oil-immersed power transformer uses metal fixed wire and voltage equalization, so as to avoid the discharge phenomenon.

4. The structure of the stain box is simple, the appearance is novel, and the body size is small. Lightweight.

5. The core is a single frame core type, DQ type is applied, 0.30mm cold rolled tends to be folded into silicon steel sheet, and tightened with new materials, replacing the traditional core-piercing screw. The coil is a concentric cylinder. Double-storey tower structure.

Many uses and applications of oil-immersed power transformers:

Oil-immersed power transformers raise the voltage level on the generation side before transmission and distribution.

At the distribution level, transformers step down (judge) voltage levels for commercial or domestic power, e.g. to generate 11 kV to 220 V single-phase and 440 V three-phase.

Voltage transformers and voltage transformers are also used in power supply systems and the industry. In addition, oil-immersed transformers are used to match the resistance. These are therefore transformers simply used with applications.

According to the exploration and application of new materials and new processes and the combination of independent innovation and technology introduction, the oil-immersed power transformer is designed according to the optimization and creative design of the core and coil structure to reduce no-load loss and noise. Self-developed products. The average no-load loss of oil-immersed power transformers decreased by 37%. The noise level is 20% lower than the average value of the current national JB/T10088-2004, and the product characteristic level has reached the domestic advanced level.
