Product Description

Amorphous alloy is a new type of magnetic and prominent energy-saving materials. With the rapid quenching solidification production process, the metal atoms are disordering and arranged non crystal. Unlike the crystal structure of silicon steel, it is easier to be magnetized and demagnetized. 80 percent of the typical amorphous alloy is composed by iron, while the other ingredient is boron and silicon. The amorphous alloy iron chip is very thin, the thickness of which is only 20 to 30um, less than 1 / 10 of the common silicon steel sheet. The characteristics of amorphous alloy core are as follows: high saturation magnetic induction intensity, low-loss (equivalent to 20% - 30% of the silicon). low coercivity, low excitation current, and stability of temperature.

Considering the characteristics of the amorphous alloy, three-phase five-volume core is used as the structure of amorphous alloy dry-type transformer, and the iron is clamped with sheet or molding frame. The structure of HV winding is multisegment and multiplayer, and LV winding is foil. The products have many excellencies as excellent energy-saving, low loss, powerful anti-short circuit capability, low partial-discharge and low noise. We successfully developed the largest capacity amorphous alloy dry-type transformer (SCBH15-2000/10) in domestic market, which one-time passed all the tests of the National Transformer Quality Supervision and Inspection Center, including all the routine tests, type tests and special tests. In a word, our company plays a leading role in design and technology both home and abroad.

Product Features

• Low loss, especially no-load loss, 70% lower than the value of GB, economy and energy saving.
• Low noise, low partial discharge, high reliability, outstanding anti-short-circuit capability, high anti-lighting impulse receptivity.
• HV winding being cast with epoxy resin at vacuum state with pressure, more excellent than without pressure.
• Simulating analysis being used in the core model, the resonance can be avoided and the noise is reduced. Simulation calculation and analysis of lighting impulse wave being used in the HV winding model, anti- lightning Impulse capability is improved.

The SCBH15 series amorphous alloy dry type transformer is a new type of energy-saving product. With excellent energy saving, and all excellences of epoxy resin dry-type transformer, the characteristics of product are as follows:

• Flameproof and no blast, no pollution, no venomous gas.
• Excellent capacity of moisture proofing and safe running at 100% relative humidity and other bad environment without pre- drying.
• Strong capacity of heat resistant.
• High over-load capability, running at 110% rated load, and 150% rated load at AF.
• Contour artistic.
• Performance and parameter conform to or excel the standards of GB, IEC or industry.

Economic Analysis

According to the State Power Industry Standard DL/T 985-2005 Guide for determining energy efficiency for distribution transformers, and the current international conventional economic evaluation methods for transformers the energy efficiency for transformers is judged by the total owning cost and the payback period of investment.

• Total owning cost (TOC) is the syntheses of the initial cost and the equal loss cost, and can fully indicate the integrative cost of the transformer.
• Total owning cost = costs of transformer equipment + costs of no-load loss + costs of load loss.
• According to the current load, the cost of no-load loss of 20-years is 58.3 RMB/W, and the cost of load loss is 21.1RMB. Taking SCBH15-630 amorphous alloy for example, contrasting with conventional SCB9-630, the price difference is about 42 965 (reference), then the cost saving of amorphous alloy transformer is TOC=-42965+58.3x(1460-410)+21.1x(5510-5200)=24791 RMB.
• Above description shows that, integrative costs of amorphous alloy dry-type transformer are less than costs of ordinary dry-type transformers.

• Without regard to the time factor of funds, investment payback period = price difference of equipment/ costs of electricity a year. Taking SCBH15-630 amorphous alloy for example, the payback period (N) is: N = 42965 /[8760 x 0.7x (1.46- 0.41+5.51-5.2)] = 5.2 years. 8760: the hours of one year, electricity costs calculated by 0.7 RMB/kWh.
• Through above analysis, amorphous alloy dry-type transformer has better economic and social benefits.
