　　Common Transformer Types in Electrical Equipment: Essential Guide for Selection

　　在電氣成套設(shè)備體系中，變壓器的類型豐富多樣，不同類型對應(yīng)不同應(yīng)用場景與功能需求。不少行業(yè)同仁在選型時(shí)容易混淆各類變壓器的適用范圍，導(dǎo)致設(shè)備適配性不佳。作為電氣成套生產(chǎn)廠家，今天就為大家拆解電氣成套設(shè)備中常見的變壓器類型，助力精準(zhǔn)選型、應(yīng)用。

　　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.

　　電力變壓器：電力系統(tǒng)的“電壓轉(zhuǎn)換核心”

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

　　電力變壓器是電力系統(tǒng)中應(yīng)用廣泛的核心類型，核心用途是實(shí)現(xiàn)電力系統(tǒng)的電壓變換，分為升壓變壓器和降壓變壓器兩大主流方向，常見電壓等級涵蓋10kV、35kV、110kV等，適配不同輸電與配電需求。

　　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.

　　其中干式變壓器以性能突出為核心優(yōu)勢，適用于對要求極高的場所，比如高層建筑、醫(yī)院、商業(yè)綜合體等人員密集或?qū)Ψ阑鸱辣袊?yán)格要求的場景，其無油化設(shè)計(jì)可避免漏油引發(fā)的隱患。

　　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.

　　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.

　　控制變壓器：設(shè)備控制回路的“穩(wěn)壓供給者”

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

　　控制變壓器的核心定位是為電氣設(shè)備的控制回路提供穩(wěn)定、精準(zhǔn)的電壓支持，滿足各類電器元件的供電需求。

　　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.

　　在電氣成套設(shè)備中，各類控制開關(guān)、繼電器、接觸器等元件都需要特定電壓才能正常工作，控制變壓器通過將主電路電壓轉(zhuǎn)換為適配的控制電壓，確保控制回路的穩(wěn)定運(yùn)行，避免因電壓波動(dòng)導(dǎo)致設(shè)備控制失靈，是保障成套設(shè)備精準(zhǔn)操控的關(guān)鍵部件。

　　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.

　　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.

　　它常用于對性要求極高的場合，比如工業(yè)自動(dòng)化生產(chǎn)線的控制回路、醫(yī)療設(shè)備供電系統(tǒng)、精密電子設(shè)備實(shí)驗(yàn)室等，能有效抑制電網(wǎng)中的雜波干擾，同時(shí)防止高壓側(cè)電流直接傳導(dǎo)低壓側(cè)，大幅降低觸電風(fēng)險(xiǎn)，為敏感設(shè)備和人員筑牢防線。

　　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.

　　自耦變壓器：平滑調(diào)壓的“靈活適配者”

　　Autotransformer: a "flexible adapter" for smooth voltage regulation

　　自耦變壓器通過單一繞組的抽頭調(diào)整實(shí)現(xiàn)電壓變換，無需獨(dú)立的高低壓繞組，結(jié)構(gòu)相對簡潔，核心優(yōu)勢是能實(shí)現(xiàn)平滑調(diào)壓。

　　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.

　　其適用場景集中在需要靈活調(diào)整電壓的場合，比如電動(dòng)機(jī)降壓啟動(dòng)環(huán)節(jié)，通過自耦變壓器的平滑調(diào)壓功能，降低電機(jī)啟動(dòng)時(shí)的沖擊電流，保護(hù)電機(jī)繞組不受損壞，同時(shí)減少對電網(wǎng)電壓的影響，廣泛應(yīng)用于工業(yè)生產(chǎn)中的各類異步電動(dòng)機(jī)控制場景。

　　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：電力系統(tǒng)的“測量保護(hù)助手”

　　Transformer: "Measurement and Protection Assistant" for Power Systems

　　互感器的核心用途是精確測量電力系統(tǒng)中的電流和電壓，同時(shí)配合儀表和保護(hù)裝置實(shí)現(xiàn)系統(tǒng)保護(hù)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.

　　在電氣成套設(shè)備中，互感器將高電壓、大電流轉(zhuǎn)換為儀表和保護(hù)裝置可承受的標(biāo)準(zhǔn)低電壓、小電流，便于操作人員通過儀表實(shí)時(shí)監(jiān)測電網(wǎng)運(yùn)行參數(shù)，同時(shí)當(dāng)系統(tǒng)出現(xiàn)過載、短路等異常情況時(shí)，能配合保護(hù)裝置快速響應(yīng)，切斷故障電路，確保電力系統(tǒng)穩(wěn)定運(yùn)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.
