250-2500 kVA
Winding connection
D/Yn-11, Y/Yn-0
Voltage HV winding
6, 10 kV
Voltage LV winding
0,4 kV
Unprotected execution (type TSL)
degree of protection IР-00
Protected execution (type TSLZ)
degree of protection IР-21
Non-excitation regulating power
±5×2,5%.


2. Assignment:

Three-phase dry-type transformers with cast insulationwith non-excitation regulating. Designed to convert electrical energy into electric three-phase alternating current with frequency of 50 Hz. Installed in industrial premises and public buildings, which have high requirements in terms of fire safety, explosion-proof, pollution-free.

Transformers are available in the version with degree of protection IP00 (without casing — type TSL) or IР21 (with casing — type TSLZ). Against overheating transformers protected thermal protection posistor, built-in winding of the low voltage and displayed on the terminals of the thermal switch. The voltage regulation of ±5% in steps of 2.5% non-excitation regulating power by moving jumpers.

from −60°C to +40°C
Thermal class
F
Thermal class of winding
Н
Fire class
F1


4. Working resource:

Operating mode
long
Warranty period
3 years
Full life
not less than 25 years


5. Construction of transformers:

The active part consists of a magnetic core made of cold-rolled electrical steel coils and switch. A special form of execution of the magnetic circuit allows you to create a connection called «STEP-LAP», which proved to be excellent low noise and low no-load losses. The finished magnetic core is covered with two-component coating for corrosion protection.

In the protected execution transformer housing made of steel sheet. After installation of the transformer hanging nuts dismantled.

 


1. Savings during installation:

Simple and inexpensive preparatory installation work. The compact size of the units.


2. Energy saving:

Reduction of losses in the lines of electricity and the cost of the cable in low voltage networks due to the close placement of the transformer to the electricity consumers. Savings in the transformer due to the low losses in the magnetic core and the windings.


3. Easy maintenance:

Transformers insulated with molded resin designed for use in severe climatic and environmental conditions, so preventive maintenance is reduced to a simple examination and verification of connections and sensors.


4. Maximum safety:

High resistance of transformers to spontaneous combustion and low emission of toxic gases as for the class F0, and for class F1. Natural cooling is carried out by atmospheric air, not fire and polluting liquids. The absence of the possibility of overheating of the transformer. Measurement and control of temperature using the thermal controllers and temperature sensors. The sensors also help to control the fan transformer.


5. Modernization performance:

Low noise level. The ability to withstand overloads. The short-term increase in load power (overload) up to 40% through the use of forced ventilation.


6. High reliability:

The absence of partial discharge. Increased reliability due to the high technological production process of the windings.
