What safety improvements does the Amorphous Alloy Dry Type Transformer have compared to the oil-immersed transformer?

In the power system, the transformer plays a vital role. With the continuous advancement of technology, the Amorphous Alloy Dry Type Transformer has gradually become a popular choice in the market. Compared with the traditional oil-immersed transformer, the amorphous alloy dry type transformer has many significant improvements in safety.
1. Improvement of fire resistance
Oil-immersed transformers mainly use insulating oil as a cooling and insulating medium, and insulating oil has flammable characteristics. During operation, if a fault occurs, causing the oil temperature to rise or a short circuit occurs, it is easy to cause a fire. Once a fire occurs, it will not only cause serious damage to the transformer itself, but also endanger the safety of surrounding equipment and personnel.
In contrast, the amorphous alloy dry type transformer uses solid insulating materials such as epoxy resin, which does not contain flammable insulating oil. This greatly improves the fire resistance of the amorphous alloy dry type transformer and greatly reduces the risk of fire. Even if a fault occurs in extreme cases, it will not cause a serious fire accident like the oil-immersed transformer.
2. Reduce the risk of explosion
Due to the large amount of insulating oil inside the oil-immersed transformer, if a serious fault occurs during operation, such as internal short circuit, overvoltage, etc., the insulating oil may vaporize rapidly, generate huge pressure, and cause the transformer to explode. Transformer explosion will not only cause serious damage to surrounding equipment and buildings, but also may endanger the lives of personnel.
Amorphous alloy dry-type transformers do not have insulating oil, and there is no risk of explosion caused by insulating oil vaporization. At the same time, the structure of dry-type transformers is relatively compact and the internal space is small, which also reduces the possibility of explosion. This makes amorphous alloy dry-type transformers safer and more reliable during use, reducing potential threats to the surrounding environment and personnel.
3. Better environmental protection performance
During the operation of oil-immersed transformers, if leakage occurs, the insulating oil will pollute the soil and water sources. Insulating oil contains a variety of harmful substances, such as polychlorinated biphenyls, which are difficult to degrade and will cause long-term harm to the environment.
Amorphous alloy dry-type transformers do not use insulating oil, and there is no problem of leakage polluting the environment. In addition, dry-type transformers are also relatively more environmentally friendly during the production process, reducing the negative impact on the environment. In today's environmentally friendly society, the environmental performance advantages of amorphous alloy dry-type transformers are more prominent.
4. Maintenance is more convenient and safe
Oil-immersed transformers need to regularly test and maintain the insulating oil, such as checking the oil level and oil quality. During the maintenance process, it is necessary to contact the insulating oil, which poses certain safety risks. At the same time, if the insulating oil needs to be replaced, a large amount of waste oil will be generated, which is also troublesome to handle.
The maintenance of amorphous alloy dry-type transformers is relatively simple and convenient. Since there is no insulating oil, there is no need to detect the oil level and oil quality. When performing maintenance work, maintenance personnel do not have to worry about contacting flammable insulating oil, which improves the safety of maintenance work. In addition, dry-type transformer fault detection and maintenance are also relatively easy, which can restore power supply faster and reduce losses caused by power outages.
5. Stronger ability to adapt to the environment
Oil-immersed transformers have certain requirements for ambient temperature and humidity. In harsh environments such as high temperature and high humidity, the performance of the insulating oil may be affected, thereby reducing the reliability and safety of the transformer.
Amorphous alloy dry-type transformers have stronger adaptability to the environment. It can operate normally in a wider range of temperature and humidity and is not affected by harsh environments. This allows amorphous alloy dry-type transformers to be used in a variety of environmental conditions, such as high temperature, high altitude, humid areas, etc., providing reliable protection for the stable operation of the power system.
Amorphous Alloy Dry Type Transformer has made significant improvements in safety compared to oil-immersed transformers. It has better fire resistance, lower explosion risk, better environmental performance, more convenient and safe maintenance methods, and stronger ability to adapt to the environment. These safety improvements have made amorphous alloy dry-type transformers more and more widely used in modern power systems.
