Product Description

110KV oil-immersed transformer

Product Features:

110kV three-phase oil immersed power transformer is manufactured according to iec60076 standard and standards gb1094.1 ~ 2-1996 and gb1094.3.5-1985 of the Electrotechnical Commission, with frequency of 50Hz, which can be used for power transmission and transformation of industrial and agricultural power grid. The new series of 110kV power transformers are characterized by low noise, low partial discharge, low temperature rise, short circuit resistance, impact resistance, no leakage and beautiful appearance.

Characteristics

1. core

High quality cold-rolled grain oriented silicon steel sheet is selected as the core, the full inclined pore free structure is adopted, and the low magnetic steel plate is used as the pull plate to firmly connect them upper and lower clamps with the core into a steel structure, so as to obtain less no-load loss and lower noise. The burr of silicon steel sheet shear port shall not be greater than 0.02mm. The no-load performance index is better than the national standard of China.

2 coil

According to the capacity of the transformer, the winding adopts cylinder, spiral, continuous and other structures. For the winding of 110kV UHV Transformer, the winding adopts tangle or inner screen structure, so as to effectively improve the distribution of impulse voltage. The conductor adopts  transposed conductor or composite conductor, so as to reduce the additional loss of the winding, and uses computer simulation to calculate the impact of electric field and winding The characteristics ensure the excellent electrical characteristics and impact strength of the winding, and the effective measures are adopted in the process to ensure its safe and reliable operation.

3 fuel tank

The oil tank adopts a flat top bell jar structure, and the box wall is welded with folded plate type reinforcing iron, which improves the mechanical strength of the oil tank. In order to reduce the stray loss of the transformer, the inner wall of the large transformer is equipped with a magnetic shield.
