　　In the electrical equipment system, there are various types of transformers, each corresponding to different application scenarios and functional requirements. Many industry colleagues tend to confuse the applicable scope of various transformers when selecting, resulting in poor equipment compatibility. As a manufacturer of electrical complete sets, today we will comprehensively disassemble the common types of transformers in electrical complete sets of equipment to assist in precise selection and efficient application.

　　电力变压器：电力系统的“电压转换核心”

　　Power Transformer: The "Voltage Conversion Core" of the Power System

　　电力变压器是电力系统中应用广泛的核心类型，核心用途是实现电力系统的电压变换，分为升压变压器和降压变压器两大主流方向，常见电压等级涵盖10kV、35kV、110kV等，适配不同输电与配电需求。

　　Power transformers are the most widely used core type in the power system, with the core purpose of achieving voltage conversion in the power system. They are divided into two main directions: step-up transformers and step-down transformers. Common voltage levels include 10kV, 35kV, 110kV, etc., and are suitable for different transmission and distribution needs.

　　其中干式变压器以性能突出为核心优势，适用于对要求极高的场所，比如高层建筑、医院、商业综合体等人员密集或对防火防爆有严格要求的场景，其无油化设计可避免漏油引发的隐患。

　　Among them, dry-type transformers have outstanding safety performance as their core advantage, and are suitable for places with extremely high safety requirements, such as high-rise buildings, hospitals, commercial complexes, and other scenarios with dense personnel or strict requirements for fire and explosion prevention. Their oil-free design can avoid safety hazards caused by oil leakage.

　　油浸式变压器则侧重散热性能优化，适用于户外安装或对散热要求较高的场所，如变电站、户外配电台区等，通过绝缘油的循环散热保障设备在高负荷状态下稳定运行。

　　Oil immersed transformers focus on optimizing their heat dissipation performance and are suitable for outdoor installation or places with high heat dissipation requirements, such as substations, outdoor distribution areas, etc. They ensure stable operation of equipment under high load conditions through the circulation of insulation oil for heat dissipation.

　　控制变压器：设备控制回路的“稳压供给者”

　　Control transformer: the "voltage stabilizer" for equipment control circuits

　　控制变压器的核心定位是为电气设备的控制回路提供稳定、精准的电压支持，满足各类电器元件的供电需求。

　　The core positioning of controlling transformers is to provide stable and accurate voltage support for the control circuit of electrical equipment, meeting the power supply needs of various electrical components.

　　在电气成套设备中，各类控制开关、继电器、接触器等元件都需要特定电压才能正常工作，控制变压器通过将主电路电压转换为适配的控制电压，确保控制回路的稳定运行，避免因电压波动导致设备控制失灵，是保障成套设备精准操控的关键部件。

　　In electrical complete equipment, various control switches, relays, contactors and other components require specific voltages to work properly. The control transformer converts the main circuit voltage into an appropriate control voltage to ensure the stable operation of the control circuit and avoid equipment control failure caused by voltage fluctuations. It is a key component to ensure accurate control of the complete equipment.

　　隔离变压器：用电的“隔离防护屏障”

　　Isolation Transformer: An "Isolation and Protection Barrier" for Electrical Safety

　　隔离变压器的核心功能是隔离输入与输出电网，通过电气隔离切断火线与零线的直接连接，有效保障设备和操作人员的。

　　The core function of an isolation transformer is to isolate the input and output power grids, cutting off the direct connection between the live and neutral wires through electrical isolation, effectively ensuring the safety of equipment and operators.

　　它常用于对性要求极高的场合，比如工业自动化生产线的控制回路、医疗设备供电系统、精密电子设备实验室等，能有效抑制电网中的杂波干扰，同时防止高压侧电流直接传导低压侧，大幅降低触电风险，为敏感设备和人员筑牢防线。

　　It is commonly used in situations that require extremely high safety, such as control circuits in industrial automation production lines, power supply systems for medical equipment, precision electronic equipment laboratories, etc. It can effectively suppress clutter interference in the power grid, while preventing high-voltage current from directly conducting to the low-voltage side, greatly reducing the risk of electric shock, and building a strong defense line for sensitive equipment and personnel safety.

　　自耦变压器：平滑调压的“灵活适配者”

　　Autotransformer: a "flexible adapter" for smooth voltage regulation

　　自耦变压器通过单一绕组的抽头调整实现电压变换，无需独立的高低压绕组，结构相对简洁，核心优势是能实现平滑调压。

　　The autotransformer achieves voltage conversion through tap adjustment of a single winding, without the need for independent high and low voltage windings. Its structure is relatively simple, and its core advantage is the ability to achieve smooth voltage regulation.

　　其适用场景集中在需要灵活调整电压的场合，比如电动机降压启动环节，通过自耦变压器的平滑调压功能，降低电机启动时的冲击电流，保护电机绕组不受损坏，同时减少对电网电压的影响，广泛应用于工业生产中的各类异步电动机控制场景。

　　Its application scenarios are concentrated in situations where flexible voltage adjustment is required, such as in the step down starting stage of electric motors. Through the smooth voltage regulation function of autotransformers, the surge current during motor starting is reduced, the motor winding is protected from damage, and the impact on the grid voltage is reduced. It is widely used in various asynchronous motor control scenarios in industrial production.

　　互感器：电力系统的“测量保护助手”

　　Transformer: "Measurement and Protection Assistant" for Power Systems

　　互感器的核心用途是精确测量电力系统中的电流和电压，同时配合仪表和保护装置实现系统保护功能。

　　The core purpose of transformers is to accurately measure the current and voltage in power systems, while cooperating with instruments and protection devices to achieve system protection functions.

　　在电气成套设备中，互感器将高电压、大电流转换为仪表和保护装置可承受的标准低电压、小电流，便于操作人员通过仪表实时监测电网运行参数，同时当系统出现过载、短路等异常情况时，能配合保护装置快速响应，切断故障电路，确保电力系统稳定运行。

　　In electrical equipment, transformers convert high voltage and high current into standard low voltage and low current that instruments and protection devices can withstand, making it easy for operators to monitor the operating parameters of the power grid in real time through instruments. At the same time, when the system experiences overload, short circuit or other abnormal situations, it can cooperate with protection devices to quickly respond, cut off the faulty circuit, and ensure the safe and stable operation of the power system.

　　特种变压器：特定工业场景的“定制化解决方案”

　　Special Transformers: Customized Solutions for Specific Industrial Scenarios

　　特种变压器是针对特定工业场景设计的专用类型，涵盖整流变压器、移相变压器、电炉变压器等多种细分品类，每种类型都具备独特的结构与性能优势。

　　Special transformers are specialized types designed for specific industrial scenarios, covering various subcategories such as rectifier transformers, phase-shifting transformers, electric furnace transformers, etc. Each type has unique structural and performance advantages.

　　其中整流变压器主要用于将交流电转换为直流电，适配电解、电镀、直流传动等工业场景；移相变压器常用于改善电网功率因数、抑制谐波污染；电炉变压器则专为工业电炉提供适配电压与功率，满足冶金、化工等行业的高温加热需求，是特殊工业生产流程中不可或缺的专用设备。
