S11 series double 35KV level distribution transformer windings non-field excitation changer
Product synopsis:
This product implements national standards GB1094 "power transformer" and GB6451 the three-phase oil-immersed power transformer technical parameters and requirements ". This product is mainly used in electric power system 35KV substation and user station. This product adopts the current domestic most advanced scientific research achievements, with novel structure, low loss, small volume, resistance to short-circuit ability, and many other features.
1, low loss, energy-saving significantly. Especially the sharply reduce no-load loss than the national standard GB/T6451-1995 average reduce about 25%.
2, core adopts the high quality cold-rolled silicon steel, domestic advanced horizontal shear line, shear burr < 0.02, all inclined seams, not punching, not fold feng yoke craft; Core column fold the double H viscose make two yoke iron three pillars to become a fastening, level off, tight whole, effectively reduce the transformer no-load loss, idle current and noise.
3, winding adopts high purity of anaerobic copper, effectively reduced copper consumption, spacers, supports a uniform electric field, pour rounded, increased reliability. Support to strengthen and improve within the winding deformation stability and prevent instability. For more than 12500KVA capacity reached by internal and external coil products, torre plate and unified whole embossed assemble all coil while backpressure, guarantee the axis of each coil highly size up and improve the consistency of emergent resistance short-circuit capacity transformer.
4, plate clip pieces and lateral beam form a firm frame structure, implement body and tank, six surface rigidity positioning sheet.the body can withstand the impact of various transportation conditions test and not occur displacement. Product transport process if less than provisions of the impact, the site by numerical hanging heart check not directly powerstation, and reduce the product test site. The large amount of work hanging heart
5 and tank box by whole steel, wall by large compressor fold pressed into corrugated structure, reduce the welding line, increased the mechanical strength, thermal expansion, improving the period of heat effect, and corrugated shape box wall avoid acoustic reflecting reducing the effects of noise. Transformer overall beautiful succinct.
6, USES the capsule storage cabinet, effectively slow the aging condition of transformer oil; Pointer type oil position idea can avoid false oil level and completely solve the problem of transformer oil light ageing problem; With the gas relay gas-collecting device, easy maintenance operation; Adopts chip radiator and large diameter low-speed low noise and improve the cooling fan and reduce the noise.
7, on the original traditional sealing structure, especially prone to oil leakage of place, from material procurement control begins, ensure steel rusty, knock against, scratch, hammer blow to the fuel tank sealing parts, special processing, and the whole of paint, thoroughly remove produced in the casing processing sharp-angled burr, welding slag, and paint adhesion to strengthen.
