Product Descriptions

Amorphous alloy is a new type of material with high magnetic conductivity and energy-saving performance. With the rapid quenching solidification production process, the metal atoms are disordered and arranged in non-crystal way. It is different from the crystal structure of tradition silicon steel and is much easier to be magnetized and demagnetized. Typical amorphous alloy steel sheet contains 80% iron, while the other ingredients are boron and silicon. The thickness of amorphous alloy steel sheet is very small, only 20 to 30um, less than 1/10 thickness of traditional silicon steel sheet. The characteristics

of amorphous alloy core are as follows: high saturation magnetic induction intensity, low-loss (20% ~ 30% of traditional silicon steel sheet), low coercive force, low excitation current and high thermal-stability.

On the basis of amorphous alloy's special characteristics, Pearl designs the new type of oil-immersed transformer with single-frame or three-phase five-limb wound core structure and fastened with thin boards and frames. The HV winding adopts sectional multi-layer cylindrical winding structure and LV winding adopts foil winding structure. The product features energy-conservation, low loss, great anti-short circuit capability, low partial discharge and low noise.

Special Features:

Low loss, especially the no-load loss, more than 70% lower than that of traditional silicon steel materials. Therefore, it is a energy-conservation product..

Low noise, low partial discharge, high reliability, high anti-short circuit and great anti-lightning impulse capability.

Simulation analyzing being used during the core mould design, to avoid cavity resonance and reduce noise level. Lighting impulse wave simulation is carried out for HV windings, to greatly improve product's anti-lightning impulse capability.

Other Advantages:
The S(B)H15 series amorphous alloy oil-immersed transformer is a new type energy-saving product. It has not only inherited the advantages of traditional oil-immersed transformer, it also has the following additional advantages.

High mechanic strength, great anti-short circuit capability, high anti-lightning impulse capability and high reliability.

High overload capability, capable of working continuously under 110% rated load.

Low loss, energy-saving, economic and maintenance-free.

Nice appearance, small-size, less installation space occupation and low engineering cost.

Each performance index and technical specification excels the China GB, national IEC and industrial standards.

Hermetically sealed corrugated tank structure is adopted for tank design, to effectively prevent air erosion to the oil and substantially prolongs transformer's service lifetime.

Core:
      Through the "three-phase five-limb" structure, frame structure and the rational design, the core is protected to prevent the core from being affected by externally applied forces and thus to ensure its no-load performance. During core mould designing, computer simulation analysis is carried out for precisely calculating the vibration frequency and scale, thus to avoid cavity resonance produced by core structure during operation. During production, special vibration-reducing and noise-decreasing materials are used. All these measures are for reducing the transformer's noise during operation.
HV winding:
      HV winding is designed with optimized structure and manufactured with high quality copper conductor, to improve the electric distribution. With the lighting impulse wave simulation calculation and analysis being carried out through special auxiliary computer software, product's anti-lightning impulse capacity is greatly improved.
LV winding:
      LV winding is manufactured with high quality foil conductor, resulting in excellent ampere-turn balance, low transverse magnetic flux leakage and higher anti-short circuit capability. By designing reasonable air conduit in the windings to increase the heat-dispersion surface, transformer's temperature rise is effectively controlled and the overload capacity is greatly improved.

Tank:
The tank is jointed with high-quality steel. Rust-removing and phosphorization processes are carried out for the tank surface, then the surface is coated with FVC anti- erosion paint, thus to effectively prevent grease pollution and chemical erosion. The appearance is nice and harmonic with the environment. The whole structure is easy for installation and maintenance. It can be widely applied in outdoor environment and under harsh conditions.

Main measures for preventing oil leakage:

1. Superior large-width steel plate is selected as material and no vertical joins on the tank wall.

All sealing flanges are products of finish machining, thus to ensure components' flatness and cleanness. Therefore, the sealing parts have very long service lifetime.

Dual-sealing structure is adopted for large and medium size tank, thus to further ensure tank rim from oil leakage.

Advanced technology is adopted during protective welding, thus fully ensure the welding quality. X-ray leakage detection is carried out for each welding seam.

All main components and parts (for example, bushing, radiator, sealing parts, butterfly valve and flap door) are purchased from the famous manufacturers recognized and certified by authority.

Superior sealing part and nitrile rubber are adopted for sealing process. The nitrile rubber is a type of oil-resistant high-elasticity product that has a reputation as "sealing expert".

Accessories:
The transformer is equipped with HV & LV bushings, oil drain valve, earthing bolt, lifting board, rating plate, pressure relief valve and other accessories. Transformers of over 800kVA power are equipped with signaling thermometer and gas relay.
On-Load Tap Changer (Optional):
When the voltage of the power network fluctuates, transformer voltage must be adjusted to supply stable electricity of high quality. Equipped with an automatic controller, the on-load tap changer can be controlled on-site or from remote computer. If necessary, we would equip and design high quality and reliable OLTC switch.
