11 KV - 2000 KVA , Oil Immersed Transformer , Low Noise Transformer

11kV - 2000kVA , Oil - Immersed Transformer, Three Phases, Two Winding, Power Distribution


Introduction


Core:


The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity, and 45° Mitring and steps overlapping structure is used for core production, thus to effectively reduce no-load loss and no-load current.

HV winding:


HV winding is manufactured with high quality copper conductor, adopting optimized structure to improve electric distribution. Lightning impulse wave process is carried out for calculation and analysis, thus to improve transformer's anti-lightning impulse capability.

LVwinding:


LV winding is manufactured with high quality foil conductor, so the ampere-turn balance is excellent and the transverse magnetic flux leakage is low. The anti-short circuit capability is thus greatly improved. Oil conduit is rationally designed in the windings to increase winding's heat dispersion surface, effectively reduce temperature and improve transformer's overload capability.


Insulation Structure:


The transformer adopts class-A insulation. The HV and LV windings are arranged in concentric way. Between the windings are oil-clapboard insulation structure built with paper cylinder and small oil conduit.


Tank:


The tank is jointed with high-quality steel. Rust-removing and phosphorization processes are carried out for the tank surface, then the surface is coated with FVC anti- erosion paint, thus to effectively prevent grease pollution and chemical erosion. The appearance is nice and harmonic with the environment. The whole structure is easy for installation and maintenance. It can be widely applied in outdoor environment and under harsh conditions.


Accessories:

This series products is applied for oil-immersed enclosed type transformer.It is

mornted on the cover of the oil tank and indicates the oil level inside.When the

window at the top part of the oil Gauge gives blue color,it means the oil level is

normal,oil elvel is above the oil tank cover;Otherwise it will indicate abnormal when

red color appears and it means the oil level is under the tank cover,oil must be

refilled.M40×1.5 screws at the top of the Oil-level Indicator act as the interface for

oil-filling connecting bube,pressure relief-valve vacuum extraction.


2.Structure and feature


2.1 Tubing oil level indicator consists of the instrument housing made of aluminum

alloy which is shaped by compressing and casting,float indicating system,protective

frame,visual window and top cover or pressure-relief-valve;Visual window is made

of thick glass tube which is inside the indicator.


2.2 Feature

---This indicator can give the correct oil level 30mm under the oil tank cover.

Indication is real,correct.The position of oil indicating can be decided by our

customers' requirements, and is given it out when they order the goods, without

special requirements the oil level indicating position will be set above the tank cover,

i.e. when the oil level is above the tank cover, float gives blue color completely,that
