Product Details

S13 High Voltage Full Sealed Oil Immersed Transformer Power Transformer10KV/0.4KV 30-1600KVA 50/60Hz

Product Introduction

The S13 fully sealed oil-immersed power transformer developed and produced by the company has the advantages of low loss, low noise, and high efficiency, which can achieve good energy-saving effects and reduce pollution. Compared with ordinary oil-immersed transformers, the fully enclosed transformer eliminates the oil conservator. The change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is isolated from the air to prevent and slow down the deterioration of the oil and the aging of the insulation. , Enhance the reliability of operation, and the normal operation is maintenance-free.

Features

1. The transformer iron core greatly reduces the no-load loss and no-load current, and the iron core is bound to ensure the tightness of the iron core and reduce noise.

2. The high and low voltage windings are made of oxygen-free copper, and the low voltage windings of 500kVA and below adopt a double-layer cylindrical structure. 630kVA and above adopt double-spiral or quad-spiral structure, and high-voltage winding adopts multi-layer cylindrical structure.

3. The transformer connection group uses Dyn11 to reduce the impact of harmonics on the power grid and improve the quality of power supply.

4. The transformer is a fully sealed structure, which prolongs the service life, does not need to hang the core and is free of maintenance.

5. The measured noise value is lower than the standard.

After this series of transformers are transported normally, the relevant parts can be installed without core checking, and the acceptance test can be carried out, and they can be put into operation after being qualified.

Structural Features

Iron core: The magnetic material of iron core uses amorphous alloy. Since the amorphous alloy does not have a crystal structure and has a soft magnetic characteristic, the area of the hysteresis loop is very narrow, the magnetization
power is small, the electrical resistivity is high, and the eddy current loss is small, so the no-load loss and no-load current of the transformer made of this material are used. very low. The core is composed of four separate core frames in the same plane
to form a three-phase five-column type. It must be annealed, and it must have a cross-barrier joint with a rectangular cross-sectional shape.

Coil: In addition to using low-voltage windings (160kVA or less) with copper conductors, a cylindrical structure made of copper foil is generally used; high-voltage windings use a multi-layered cylindrical structure to balance the winding ampere distribution and magnetic flux leakage. High-voltage and low-voltage windings are wound together with wire tension devices to form rectangular coils, and the coils are solidified by hot-pressing and shaping to enhance the mechanical strength of the windings and the ability to withstand short circuit.

Oil tank: It adopts a beautiful full-sealing and maintenance-free corrugated structure. Through advanced oil tank production technology,it undergoes strict pressure...
