1. Basic characteristics of special transformers


1. Wide voltage range


Special transformers usually need to work under relatively high voltage, so its insulation performance needs to be guaranteed. Therefore, its insulation layer is generally thicker than that of ordinary transformers, and the quality of the insulation material is also higher.


2. High reliability


Special transformers usually work under harsh conditions, such as high humidity, high temperature, oil pollution and other environments, so their reliability requirements are very high, and strict quality control is required to ensure their reliability.


3. Small size and light weight


Special transformers usually require small size, light weight, and easy installation, transportation and maintenance.


4. Flexible design and excellent performance


The design of special transformers should take into account the requirements of different applications. For example, high-frequency applications require transformers to have good high-frequency response characteristics; military applications require transformers to have anti-interference capabilities, etc.


Second, the classification of special transformers


According to different working environments, special transformers can be classified into


1. High temperature transformer


High-temperature transformers are used in high-temperature environments, such as electric arc furnaces, electric melting furnaces, etc. It adopts special insulating materials and design methods, so that it can withstand the work in high temperature environment, while ensuring safety and reliability.


2. Special medium transformer


Special medium transformers are suitable for special medium environments, such as petrochemical, nuclear industry, special chemical production and other occasions. It requires special insulating materials and design methods to ensure its reliability and safety.


3. High frequency transformer


High-frequency transformers are mainly used in high-frequency electronic equipment such as communications, television, and radar, and their operating frequencies are usually between tens of MHz and several GHz. It requires special insulating materials and design methods so that it has good high-frequency response characteristics while ensuring electrical performance and reliability.


4. Power Transformer


A power transformer is a transformer specially used in power systems. It needs to have high quality and reliability to ensure the normal operation of the power system.


5. Military transformers


Military transformer is a kind of transformer specially used in the military field. It needs special properties such as anti-interference ability and anti-electromagnetic pulse ability to meet the requirements of military equipment.


3. Application fields of special transformers


Special transformers are widely used in fields such as electric power, electronics, communications, aviation, and military industry.


1. Electric field


Power transformers are mainly used in power grids to transform voltage, increase voltage, etc. For example, high-voltage transformers must be used on transmission lines to transform the voltage in order to reduce transmission losses.


2. Electronic field


High-frequency transformers are widely used in electronic equipment such as communications, television, and radar. These devices require high frequency transformers for power supply or signal processing.


3. Communication field


Special transformers such as special dielectric transformers and high frequency transformers are required in communication equipment. These transformers have good electrical performance and reliability and can help keep communication equipment running properly.


4. Aviation field


In avionics equipment, special transformers such as high-temperature transformers and military transformers are required. These transformers need to meet the requirements of small space, light weight and high reliability to meet the special requirements of the aviation environment.


5. Military field


Special transformers such as special dielectric transformers and military transformers are widely used in the military industry. These transformers need to have special properties such as anti-interference ability and anti-electromagnetic pulse ability to meet the requirements of military equipment.


In short, special transformers are one of the important equipment in the fields of electric power, electronics, communication, aviation, military industry and so on. It needs to be designed according to different working environments and usage requirements to meet the requirements of different applications. With the continuous development of science and technology, the application range of special transformers will be more extensive.
