Three-phase flat coil core fully sealed distribution transformer

· Three-phase plane coil core fully sealed distribution transformer capacity range of 30KVA~1000KVA, a total of 15 varieties.

· The core is a three-phase, three-column internal and outer frame roll structure. High degree of mechanization.

· The high and low pressure coil is continuously wound on the core column, with good concentricity and tight coil.

· Main technical and economic indicators have reached the international advanced level of similar products.

·Core:structure of three phase three pillar type rolled inside and outside the box,column for multistage ladder circular cross section;Core coiling by vacuum annealing after removing stress;Trough bending clip,pull the screw tighten body;Core surface coating is special glue,ensure that core deformation,do not rust.

·Winding and body:low voltage winding for 1~6 wire and around four layer or double layer cylindrical (500 KVA and below)or spiral winding(630 KVA and above);Anaerobic copper conductor adopts control;High and low voltage winding layer ask insulation tape for ling lattice point;High voltage winding axial oil and the empty between high and low pressure oil gap to stay shade structure;Iron yoke insulation and trapezoidal block is an organic whole,make body even under pressure;Body structure of new type hanger position,vertical and horizontal orientation,ensure displacement of solid body.

·Tank:adopt corrugated tank,sealed structure,not leak,maintenance free.

Performance Characteristic

· Compared with the "9" transformer, the no-load loss is reduced by about 30% on average.

· Compared with JB / T10088-1999 standard, the noise is low, with about 7 dB lower.

· The temperature rise of oil surface and high and low pressure winding is about 20K-13K lower than the temperature rise limit, and has a certain overload capacity.

· Strong short-circuit resistance and high reliability.
