CEEG Dry-type Rectifier Power Transformers Manufacturer

PRODUCT OVERVIEWS

The successful application of rectifier dry-type transformer in Yantai Longyuan plasma ignition system has attracted the attention and coverage of CCTV News, demonstrating the outstanding strength and technological innovation of China Electric in the field of power equipment.

Performance Characteristics：

Safe and reliable

Made of non-toxic and flame-retardant epoxy resin infusion, with high mechanical strength, flame retardant, fire-resistant, and pollution-free.

Easy installation

The whole machine can enter the site and be put into operation once it is in place, which is convenient and easy.

Insulation and heat resistance

H-level insulation is heat-resistant, capable of withstanding 180 ℃ and high overload force ≤ 200%.

Saving Investment

It can be installed in combination with electrical equipment such as rectifiers to save space and reduce investment.

Manufacturing Process:

Reliability of Insulation Technology

From the initial two-dimensional electric field simulation, three-dimensional electric field measurement, and impulse characteristic measurement, to the later theoretical analysis and simulation tests on the characteristics of the transformer's main insulation, longitudinal insulation, end insulation, lead insulation, and coil under lightning impulse voltage, the reliability of the insulation is ensured.

Calculation of leakage magnetic field and reduction of stray losses

Research is conducted specifically on the calculation and measurement of transformer leakage magnetic field, shielding structure of leakage magnetic field, calculation of transformer dynamic and thermal stability, and improvement of transformer dynamic and thermal stability capabilities to ensure the calculation of leakage inductance field and reduce stray losses.

Accurate analysis of coil temperature field

Our company has developed a calculation program for the temperature field of the coil, which accurately calculates the temperature distribution of the coil and the temperature rise of the hot spot by calculating the loss distribution and flow velocity field cooling condition of the coil, in order to take measures.

Reduce the local discharge of transformers

The electric field strength of each part has been analyzed and strictly controlled during the design phase.
