1 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.

2 Structure

 

Core: cold rolled grain-oriented silicon steel

HV winding: copper conductor

LVwinding: foil conductor


Insulation Structure: The transformer adopts class-A insulation. 


Tank: The tank is jointed with high-quality steel.

 

 

3 Importance Notices for Installation

 

Permitted overload

 

There are two types of overloading conditions, that is, normal overloading and emergency overloading. Normal overloading could happen at any time and continuously, provided that the permitted values follows the principles determined by the loading curve, cooling medium temperature and the load value before overloading. Emergency overloading could happens occasionally under emergency, provided that the permitted values follows the principles determined by the loading curve, cooling medium temperature and the load value before overloading. The emergency overloading could only happen in case of some emergency occurs. For example, one of multiple transformers is out of service and no backup transformer is available, in which case, the other transformers are running in emergency overloading status.
