1.Product model meaning


2.product characteristics

1, low loss, significant energy saving. In particular, the no-load loss is greatly reduced, which is about 25% lower than the national standard GB/T6451-2008.
2, the core adopts high-quality cold-rolled silicon steel sheet, the domestic advanced transverse cutting line, cutting burr < 0.02mm, full oblique joint, no punching, no stacking iron yoke process; The double H adhesive makes the three columns and two yoke of the core become a tight, flat and compact whole, which effectively reduces the no-load loss, no-load current and noise of the transformer.
3, the transformer coil adopts high purity oxygen-free copper, which effectively reduces copper consumption. Coil pad and stay fillet treatment, electric field uniform, reliability increased. The inner winding support is strengthened to improve its stability and prevent instability and deformation. For products with a capacity of more than 16000KVA, the internal and external coils use a unified integral plate and pressure plate to assemble the coils at the same time, to ensure the consistency of the height and size of the coils along the axis, and improve the ability of the transformer to resist sudden short circuit.
4, the plate clamp and the side beam form a solid frame structure, the body and the six sides of the tank steel positioning, so that the body can withstand the impact test under various transportation conditions without displacement. If the impact is less than the specified value during the transportation of the product, the site can be directly tested and put into operation without the core inspection, which reduces a lot of work on the product site.
5, the tank wall adopts the whole steel plate, which is folded into a corrugated structure by a large press, which reduces the weld, increases the mechanical strength, expands the thermal area, and improves the heat dissipation effect. At the same time, the corrugated box wall avoids the plane reflection of the sound wave to reduce the noise. The transformer is beautiful and simple.
6, the capsule type oil storage tank effectively slows down the aging degree of transformer oil; The pointer type oil level meter can avoid the occurrence of false oil level phenomenon and solve the problem of light aging of transformer oil. Gas relay with gas collecting device for easy maintenance and operation.
7, for the original traditional sealing structure, especially where there is easy to leak oil, start from the material procurement control to ensure that the steel does not rust, bump, scratch, hammer, special processing of the oil tank sealing part, and the overall painting of the box, remove the sharp corner burrs and welding slag generated in the processing of the box, and strengthen the adhesion of the paint.
