The classification of commonly used transformers can be summarized as follows [3]:
1. According to the number of phases:
1) Single-phase transformer: for single-phase load and three-phase transformer group.
2) Three-phase transformer: used for the rise and fall voltage of three-phase systems.
2, according to the cooling method:
1) Dry-type transformer: relying on air convection for natural cooling or increasing fan cooling, it is mostly used for small-capacity transformers such as high-rise buildings, high-speed toll stations, local lighting, and electronic circuits.
2) Oil-immersed transformer: rely on oil as cooling medium, such as oil-immersed self-cooling, oil-infiltrated air-cooled, oil-immersed water-cooled, forced oil circulation, etc.
3. According to the purpose:
1) Power transformer: used for the rise and fall voltage of transmission and distribution systems.
2) Instrument transformers: such as voltage transformers, current transformers, measuring instruments and relay protection devices.
3) Test transformer: It can generate high voltage and carry out high voltage test on electrical equipment.
4) Special transformers: such as electric furnace transformers, rectifier transformers, regulating transformers, capacitive transformers, phase shifting transformers, etc.
4, according to the form of winding:
1) Two-winding transformer: used to connect two voltage levels in the power system.
2) Three-winding transformer: Generally used in power system regional substation, connecting three voltage levels.
3) Autotransformer: A power system used to connect different voltages. It can also be used as a normal boost or post-down transformer.
Hongxin Power Equipment Co. , Ltd. is a professional enterprise engaged in the production, research and development, and sales of power transformers (American transformers, oil transformers, dry transformers, etc.), high and low voltage switchgear and related products. Processing, product research and development, and merchandise trade are integrated into one, which is a high-tech industry that has begun to take shape. The company is located in Zhangji Town Industrial Park, Tongshan District, Xuzhou City. Since its inception, the company has always adhered to the business philosophy of “Science and technology, service first, integrity-basedâ€, taking the customer's major interests as its mission, seeking pragmatism, innovation and innovation, providing users with perfect transformer solutions to meet all levels. Customer needs.
2. Diverse uses: Home Theater Projector will be equipped with intelligent systems, which contain a large number of film sources. In addition, the projector can also be connected to different devices through different interfaces, such as game consoles, computers, U disks, etc. Only one machine can realize online drama, listening to songs, games, office and other functions.
3. Diffuse reflection eye protection: Home Theater Projector uses the principle of diffuse reflection to form images, which is less harmful to the eyes than the LCD screen.
4. Diverse usage scenarios: Home Theater Projector can adapt to different sizes of bedrooms, living rooms and even dedicated audio-visual room scenes due to its different brightness.
According to the increase of people's needs, the forms of Home Theater Projector are also becoming more and more diverse. In the past, people's impression of Home Theater Projector was mostly a square box placed on a cabinet or suspended from the ceiling, but there are already portable projectors that take into account both the sense of use and the size. In addition to portable micro-projectors, larger home laser TVs are also developing rapidly. Many users have abandoned traditional LCD TVs and opted for home projectors when decorating. It can also be seen from this that Home Theater Projector has a trend of gradually replacing LCD TVs.

The biggest difference between Home Theater Projector and ordinary business projectors is the resolution and ease of use. Most of the mainstream Home Theater Projectors have a resolution of 1080P Full HD, and are equipped with an intelligent system, which makes the projector more convenient to use. Home Theater Projector mainly pursues brightness, color, and contrast, which can bring users an immersive and realistic experience.
Features
1. Large screen: The size of traditional LCD TVs is mostly between 40-70 inches, while the Home Theater Projector can easily project 100-150 inches of screen content.2. Diverse uses: Home Theater Projector will be equipped with intelligent systems, which contain a large number of film sources. In addition, the projector can also be connected to different devices through different interfaces, such as game consoles, computers, U disks, etc. Only one machine can realize online drama, listening to songs, games, office and other functions.
