dry type reactor,
oil immersed type transformer
10kV - Class Cast Resin Dry Type Transformer, Three Phases, Two Winding, Power Distribution
The rated voltage ratios at no-load shall be 11000/433 V and shall be related to the principle tap
position of the transformer.
Unless otherwise specified, the rated power in kVA for every tap position of the transformer to
be offered shall either be one of the followings
Windings Connections & Vector Group
The windings are to be connected as follows:
High Voltage (HV) Winding Delta connected
Low Voltage (LV) Winding Star connected with neutral brought out
Vector Group Dyn 11
The neutral connection shall be capable of carrying full phase rated current.
Method for voltage regulation shall be provided by means of an off circuit tap changer on the
HV winding to provide a variation of the transformer ratio by + 5%, + 2.5%, 0%, - 2.5% and -
5%. Dedicated tapping selection shall be made by the use of bolted links. These bolted links for
changing the taps shall be arranged on the same side where the HV terminals are positioned.
Method of tap changing by means of changing of HV tapping connection is not permitted.
Pearl Electric boasts an experienced R&D team of 65 talented engineers, whose main duties are to design the contracted and customized products upon customer's special requirements. With this team of engineers, Pearl Electric is capable of respond to customer's inquiry at first time and also ensures the accurate product quotation.
To precisely calculate resonance frequency and intensity and avoid cavity resonance generated by the core structure during operation, simulation analysis is carried out for core mould design. Flexible connections are made between core and coils, core and bogie. With these measures adopted, the noise level is reduced by 10~15dB compared with the international standard.
During the HV winding design, rational structure is adopted to improve the electric distribution. With the lighting impulse wave simulation calculation and analysis being carried out with special auxiliary software, product's anti-lightning impulse capacity is greatly improved.
