Amorphous alloy transformer Composition

Composition of amorphous alloy transformer
Amorphous alloy transformer is mainly composed of the following key parts:

1. Core

Material: The core is the core component of the amorphous alloy transformer, which is wound with amorphous alloy strip. Amorphous alloy is composed of 78%81% steel, 13.5% boron, 3.5%7% silicon, 2% carbon and other small amounts of elements, with excellent magnetic conductivity and low loss characteristics.

Structure: The core is usually composed of four separate core frames in the same plane to form a three-phase five-column structure, which helps to reduce flux leakage and eddy current loss. The core needs to be annealed to improve its magnetic properties, and has a cross-iron yoke seam, and the cross-section is rectangular.
2. Winding

Material: The winding is usually made of high-quality copper or aluminum wire to ensure good conductivity and heat dissipation.

Structure: The winding has a rectangular cross-section and can be wound and formed separately, divided into double-layer or multi-layer rectangular layers. The design of the winding needs to take into account factors such as current density, insulation performance and heat dissipation performance.

3. Oil tank

Material: The oil tank is one of the important components of the amorphous alloy transformer, usually welded with high-quality steel plates.

Structure: The oil tank is a fully sealed maintenance-free corrugated structure with good sealing and heat dissipation performance. The surface of the oil tank is usually treated with dust spraying and other treatment processes to improve its anti-corrosion performance.

4. Transformer oil

Function: Transformer oil plays the role of insulation, heat dissipation and arc extinguishing in the transformer.

Quality: Transformer oil needs to have high purity and high insulation performance to ensure the safe and stable operation of the transformer.

5. Insulating bushing

Function: The insulating bushing is used to electrically isolate the winding from the oil tank and other components to ensure the safety performance of the transformer.

Material: The insulating bushing is usually made of high-quality insulating materials, such as ceramics or organic composite materials.

6. Exhaust device

Function: The exhaust device is used to discharge the heat inside the transformer to maintain the normal operating temperature of the transformer.

Type: The exhaust device can be in the form of a fan or a radiator, depending on the design and use conditions of the transformer.

VII. Safety protection device

Composition: All series transformers are equipped with pressure relief valves, and gas relays with alarm and trip terminals can be installed according to user needs.

Function: These safety protection devices are used to take timely measures to protect the safety of transformers and power systems when transformers fail or are in abnormal conditions.

In summary, amorphous alloy transformers are composed of multiple key parts such as core, winding, oil tank, transformer oil, insulating bushing, exhaust device and safety protection device. These components work together to ensure that amorphous alloy transformers have excellent performance such as high efficiency, energy saving, stability and safety.
