Dry three-phase transformer: an ideal choice for industrial, electric vehicle chargers, and medical design

Bel Fusion has expanded its three-phase dry-type transformer series, which is suitable for medical, 工業用, 点灯, electric vehicle charging, and green energy applications. The 3PH series dry-type transformers of the Bel fuse signal transformer department can meet various requirements and are permanently configured for 3-phase DELTA input and WYE output. The electrostatic shielding (ESS) between input/output windings attenuates line noise by preventing poor signal feedback and serves as a safety function in the event of a single fault. The dry-type rigid transformer adopts a sturdy H-class (180 ℃), enhanced UL 1446 document E66312 insulation system, 4KV dielectric withstand rating, maximum self-heating temperature of 130 ° C @ maximum ambient temperature of 40 ℃, and low leakage current capacity. The target applications include MRI, radiation and other medical equipment, machine tools, 溶接機, そして風, solar, and lighting power conversion systems. The operating frequency of the rigid transformer is 50 または 60 Hz, providing a power range of 2KVA to 35KVA, with a maximum input voltage of 500 VAC and a maximum load current of 69A RMS, with an efficiency higher than 93%. All 3PH models are UL certified, comply with UL 60601-1 medical standards, and can be designed according to UL document E151299.

Dry Type Transformer is a special type of transformer. The core components of the TransformerTransformer are the coil and iron core, which use special insulation materials to prevent oil leakage and other hazards during operation. Dry-type transformers are more environmentally friendly and safe than traditional oil-immersed transformers.

The characteristics of Dry Type Transformer:

1. Environmental safety: Since oil is not an insulation medium, there are no safety hazards such as oil leakage and fire, making it more environmentally friendly.

2. Efficient and energy-saving: Dry-type transformers have lower losses and can reduce energy waste.

3. メンテナンスが簡単: Due to the lack of oil, there is no need for oil sample inspection, oil change, and other maintenance work, which reduces maintenance costs.

4. Strong adaptability: Dry-type transformers can adapt to rough environmental conditions, such as high temperature, 低温, 湿度, 等.

Application of Dry Type Transformer:

1. 電力システム内, dry-type transformers are widely used as key equipment for transmission and distribution.

2. Industrial field: In the industrial field, dry-type transformers are often used in various production equipment and machines as power supply equipment.

3. Construction field: Dry-type transformers have been widely used in high-rise buildings, 地下鉄, and other places due to their safety performance, such as fire and explosion prevention.
