電氣成套設(shè)備是指將多個電氣設(shè)備按照一定的規(guī)范（圖紙、技術(shù)要求、工藝要求）組合在一起，形成一個有機的整體，以實現(xiàn)特定的電氣功能，并為工業(yè)和商業(yè)應(yīng)用提供服務(wù)的設(shè)備系統(tǒng)。這些設(shè)備通常包括：

　　Electrical complete equipment refers to a device system that combines multiple electrical devices according to certain specifications (drawings, technical requirements, process requirements) to form an organic whole, in order to achieve specific electrical functions and provide services for industrial and commercial applications. These devices typically include:

　　開關(guān)柜：包含斷路器、隔離開關(guān)、接地開關(guān)等，用于控制和保護(hù)電路。

　　Switchgear: includes circuit breakers, isolating switches, grounding switches, etc., used for controlling and protecting circuits.

　　配電柜：用于變壓器二次繞組及其負(fù)載側(cè)的配電，包括一級、二級和三級配電箱。

　　Distribution cabinet: used for the distribution of transformer secondary windings and their load side, including primary, secondary, and tertiary distribution boxes.

　　控制柜：用于自動化控制和保護(hù)系統(tǒng)，可能包含PLC、DCS等控制系統(tǒng)。

　　Control cabinet: used for automation control and protection systems, which may include control systems such as PLC and DCS.

　　電源柜：提供穩(wěn)定電源供應(yīng)的設(shè)備。

　　Power cabinet: a device that provides stable power supply.

　　變壓器：用于電壓的升高或降低。

　　Transformer: Used for increasing or decreasing voltage.

　　電動機：用于驅(qū)動機械設(shè)備的電動機。

　　Electric motor: an electric motor used to drive mechanical equipment.

　　斷路器：用于電路的接通和斷開，保護(hù)電路不受過載和短路的影響。

　　Circuit breaker: used for connecting and disconnecting circuits, protecting them from the effects of overload and short circuit.

　　接觸器：用于遠(yuǎn)距離控制電路的接通和斷開。

　　Contactor: Used for connecting and disconnecting remote control circuits.

　　熔斷器：用于電路的保護(hù)，當(dāng)電流超過設(shè)定值時自動熔斷。

　　Fuse: Used for circuit protection, it automatically melts when the current exceeds the set value.

　　電容器：用于改善電能質(zhì)量，如減少諧波、提高功率因數(shù)等。

　　Capacitor: Used to improve power quality, such as reducing harmonics, increasing power factor, etc.

　　電纜和連接器：用于連接各個電氣設(shè)備。

　　Cables and connectors: used to connect various electrical equipment.

　　保護(hù)裝置：如繼電保護(hù)裝置，用于在電力系統(tǒng)故障時切斷故障部分，保護(hù)系統(tǒng)不受損害。

　　Protection device: such as relay protection device, used to cut off the faulty part in case of power system failure, protecting the system from damage.

　　電氣成套設(shè)備的應(yīng)用領(lǐng)域非常廣泛，包括電力系統(tǒng)、工業(yè)自動化、建筑電氣等。了解這些設(shè)備的組成和功能對于從事相關(guān)行業(yè)的人員來說非常重要，有助于合理選擇和操作

　　The application fields of complete electrical equipment are very wide, including power systems, industrial automation, building electrical, etc. Understanding the composition and functions of these devices is very important for personnel engaged in related industries, as it helps to make reasonable choices and operations
