(1) Cause: <\/strong><\/h6>\n

This loss occurs due to the internal friction within the transformer’s core material. As the alternating magnetic field constantly reverses direction, the magnetic domains in the core material must realign, a process that consumes energy and dissipates it as heat.<\/p>\n

(2) Key Influencing Factor: <\/strong><\/h6>\n

The lower the coercivity of the core material, the smaller the area of its hysteresis loop, resulting in lower hysteresis loss.<\/p>\n

1.2\u6e26\u96fb\u6d41\u640d\u5931<\/strong><\/h4>\n
(1) Cause:<\/strong><\/h6>\n

The alternating magnetic field induces circulating currents (eddy currents) within the conductive core material. The electrical resistance of the core converts the energy of these currents into heat (Joule heating).<\/p>\n

(2) Key Influencing Factors:<\/strong><\/h6>\n

Directly related to the core material’s resistivity, lamination thickness, and magnetic flux density.No-load loss is an inherent characteristic of a transformer. It occurs continuously whenever the transformer is energized, regardless of whether it is supplying any load. Therefore, investing in low no-load loss transformers offers a clear path to operational savings.<\/p>\n\n\n\n\n\n\n\n

2.1.1 Action:<\/strong><\/h5>\n

Employ High-Grade Grain-Oriented Silicon Steel (GOES), such as Japan’s JFE JNEX series, Germany’s ThyssenKrupp Hi-B steel, or China’s Baosteel B20R070.<\/p>\n

2.1.2 How It Works:<\/strong><\/h5>\n
(1) Crystal Orientation Optimization:Special rolling and annealing processes align the silicon steel grains so their easy-magnetization direction is consistent with the rolling direction. This makes magnetization easier, significantly reducing hysteresis loss.<\/strong><\/h6>\n
(2) Increased Silicon Content:Adding silicon (typically 3%-3.5%) increases the core’s resistivity. According to the formula for eddy current loss<\/strong><\/h6>\n

(1) Action: <\/strong><\/h6>\n

Replace traditional silicon steel with Amorphous Alloy (e.g., Metglas) ribbon to form the transformer core.<\/p>\n

2.2.1 How It Works:<\/strong><\/h5>\n
(1) Disordered Atomic Structure: <\/strong><\/h6>\n

Amorphous metal is formed by ultra-rapid cooling (millions of degrees per second), creating a glassy, non-crystalline structure with long-range atomic disorder. This eliminates the impediment of grain<\/p>\n

(2) boundaries to magnetic domain wall movement, resulting in extremely low coercivity. Hysteresis loss can be just 20%-30% of that in traditional silicon steel.<\/strong><\/h6>\n
2.2.2 High Resistivity: <\/strong><\/h5>\n

Amorphous alloys have a resistivity approximately three times higher than silicon steel, drastically suppressing eddy current loss at the source.<\/p>\n

2.3.1 Action:<\/span> <\/strong><\/h5>\n

Utilize Step-Lap joint configurations in the core and minimize the number of joints.<\/p>\n

2.3.2 How It Works:<\/strong><\/h5>\n
(1) Reducing Local Magnetic Reluctance:<\/strong><\/h6>\n

Traditional butt-lap joints cause severe magnetic flux distortion and high-loss transverse flux. Step-lap joints create a smooth transition, leading to more uniform flux distribution and a significant reduction in stray loss at the joints.<\/p>\n

(2) Controlling Stacking Pressure and Annealing: <\/strong><\/h6>\n

Precise stacking pressure ensures core compactness, avoiding additional losses from vibration. Annealing in a protective atmosphere relieves processing stresses in the laminations, restoring their optimal magnetic properties.<\/p>\n

In the global context of energy transition and industrial energy efficiency, reducing transformer no-load loss has become a key focus for the power industry, industrial enterprises, and commercial users alike. According to the International Energy Agency (IEA), transmission and distribution losses account for about 8% to 15% of total global electricity generation, with transformer no-load losses representing a significant portion of this. Whether you operate distribution transformers, power transformers, or dry-type transformers, optimizing no-load performance can directly lower your electricity costs. For facilities with transformers running 24\/7 \u2013 such as data centers, hospitals, and continuous production plants \u2013 the energy savings from minimizing no-load loss are particularly substantial.
