Three Phase Oil Immersed Transformer 33kV 50 kVA For Agricultural Power Grids
Oil Immersed Transformer Applicable Location:
The Oil Immersed Transformer products are mainly used in urban and rural industrial and agricultural power grids and various industrial and mining enterprises and power transmission and distribution projects.
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.
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.
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.
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.
The transformer, tap changing equipment and supplementary cooling equipment shall comply with the values stated in Table 1 — Audible sound levels for oil-immersed power transformers and be verified in accordance with IEC 60076-10.
The transformer shall be designed to meet the dBA noise level specified in schedule A of an enquiry document.
