Performance characteristics
Compared with the "9" type transformer, the no-load loss of this transformer is reduced by about 30% on average. Compared with JB/T10088-1999 standard, the noise is low, about 7dB lower. The temperature rise of oil level and high and low voltage windings is about 20K-13K lower than the limit value of temperature rise, with certain overload capacity. Strong short-circuit resistance and high reliability.
structure characteristics
Iron core: three-phase three-column inner and outer frame rolling structure is adopted, and the core column is of multi-stage stepped circular section; After the core is rolled, the stress is removed by vacuum annealing; Trough-shaped bending clip, pull screw tensioner body; The surface of the iron core is coated with special adhesive to ensure that the iron core does not deform and rust. Winding and body: low-voltage winding is a four-layer or double-layer cylindrical winding (500kVA and below) or spiral winding (630kVA and above) with 1~6 conductors winding in parallel; The conductors are drawn with oxygen-free copper; The interlayer insulation of high and low voltage windings is rhombus dot adhesive tape; The axial oil passage of the HV winding and the oil gap of the main air passage between the high and low voltage are of the strut-curtain structure; The iron yoke insulation is integrated with the trapezoidal cushion block to make the body evenly compressed; The body adopts a new hanging plate positioning structure, which is positioned vertically and horizontally to ensure that the body is stable and not displaced. Oil tank: adopt the sealed structure of corrugated oil tank without oil leakage and maintenance.
