150 kva Oil-immersed power transformers

Product Introduction

The oil-immersed power transformer is a new type of high-performance transformer with a more reasonable structure and better performance. Its three-dimensional coiled iron core is arranged in an equilateral triangle. There is no air gap in its magnetic circuit, and the winding is tighter. The length of the three magnetic circuits is the same and the shortest. The cross-sectional area of the iron core core column is closer to the circle, so the performance is further improved, the loss is reduced, the noise is reduced, and the three harmonic component is reduced. The product is more suitable for the power grid transformation of urban and rural areas, industrial and mining enterprises, and it is more suitable for combined transformers and transformers for pre-installed substations.

Oil-filled power transformers refer to transformers in which the winding uses insulating oil as the insulating medium. The power distribution transformer is one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings. It reduces the network voltage of 10 (6) kV or 35kV to the 230/400V bus voltage used by the user.

Advantages

1. Oil-Type power transformer has good insulation performance and good thermal conductivity, and at the same time, transformer oil is cheap.

2. It can solve the problem of large-capacity heat dissipation and high-voltage insulation of the transformer.

FAQ

1.What is an oil-filled power transformer?

An oil immersed transformer houses its core and windings submerged in insulating oil, which serves three critical functions: Cooling: The oil absorbs and dissipates heat generated during operation. Insulation: It prevents electrical breakdown by insulating live components.

2.Why are power transformers filled with oil?

Transformer oil's primary functions are to insulate and cool a transformer. It must therefore have high dielectric strength, thermal conductivity, and chemical stability, and must keep these properties when held at high temperatures for extended periods.
