Introduction

 

Oil-immersed type transformer features low noise, low loss, rational structure, high quality material, scientific design, strict production technology and advanced test method. The product also has the following additional advantages:


1. High mechanic strength, great anti-short circuit capability, excellent anti-lightning impulse capability and high reliability. All these performance indexes rank first in the industry in China.


2. Excellent overload capability, capable of continuously working under 110% rated load.


3. Low loss, energy-saving, economic and maintenance free.


4. Nice appearance, small size, less installation space occupation and low engineering cost.


5. Each performance index and technical specification excels that specified in China GB, international IEC and industrial standards.


6. Hermetically sealed corrugated tank structure is adopted, thus to effectively prevent air corrosion to the oil and prolong service lifetime of the transformer.

Study  of Amorphous alloy 

 

The invention discloses an amorphous alloy transformer which comprises a box, and a high-voltage electric pole and a low-voltage electric pole which are disposed on the box. A cover is disposed on the box. The amorphous alloy transformer is characterized in that a 15KV-20KV transformer high-voltage coil is disposed in the box, the amount of the main coils of the high-voltage coil is 1-2 times of that of the sub-coils of the high-voltage coil, the main coils and the sub-coils are distributed at two ends of the high-voltage coil, the tap points of the main coils and the sub-coils are connected with branch control switches between the high-voltage electric pole and the low-voltage electric pole, and a double-layer rubber plate is disposed at the base plate at the bottom of the box. By using the branch control switches, high-low voltage change is achieved, and capital and resources for repeatedly purchasing a large amount of equipment are saved.
