常見的低壓配電柜、高壓配電柜其實并不是單單指配電柜本身，它實際上是我們俗稱的成套設(shè)備，其實這種叫法是不準確的，學名應(yīng)該是“成套配電裝置”。

　　The common low-voltage distribution cabinet and high-voltage distribution cabinet actually refer not only to the distribution cabinet itself, but also to what we commonly call a complete set of equipment. In fact, this term is inaccurate, and the scientific name should be "complete set of distribution equipment".

　　那么什么是成套配電裝置，它有哪些特點呢?

　　So what is a complete set of power distribution equipment and what are its characteristics?

　　什么是“成套配電裝置”?開關(guān)柜(又稱成套開關(guān)或成套配電裝置)，它是以斷路器為主的電氣設(shè)備;成套配電裝置是制造廠成套供應(yīng)的設(shè)備，由制造廠預(yù)先按照主接線的要求，將每一回路的電氣設(shè)備高低壓電器(包括控制電器、保護電器、測量電器、如斷路器、隔離開關(guān)、互感器等)以及母線、載流導(dǎo)體、絕緣子等，裝配在封閉或半封閉的金屬柜中，構(gòu)成個單元電路分柜，此單元電路分柜成為成套配電裝置。安裝時，按主接線方式，將各單元分柜(又稱間隔)組合起來，就構(gòu)成整個配電裝置。

　　What is a 'complete power distribution device'? A switchgear (also known as a complete set of switches or distribution equipment) is an electrical equipment mainly composed of circuit breakers; A complete set of power distribution equipment is a set of equipment supplied by a manufacturing plant. The manufacturer pre assembles the high and low voltage electrical equipment (including control appliances, protection appliances, measuring appliances, such as circuit breakers, isolating switches, transformers, etc.), busbars, current carrying conductors, insulators, etc. of each circuit in a closed or semi closed metal cabinet according to the requirements of the main wiring, forming a unit circuit cabinet. This unit circuit cabinet becomes a complete set of power distribution equipment. When installing, according to the main wiring method, the various unit cabinets (also known as intervals) are combined to form the entire power distribution device.

　　在電器成套設(shè)備中把母線、隔離開關(guān)(高壓)、刀開關(guān)(低壓)、斷路器(空氣開關(guān))、電壓互感器、電流互感器、電力變壓器、交流接觸器、保護繼電器(熱繼電器)、避雷器等組成的設(shè)備叫一次設(shè)備。由它們按照原理關(guān)系所組成的回路稱為一次回路或一次方案圖。

　　The equipment composed of busbars, isolating switches (high voltage), knife switches (low voltage), circuit breakers (air switches), voltage transformers, current transformers, power transformers, AC contactors, protective relays (thermal relays), lightning arresters, etc. in electrical equipment sets is called primary equipment. The circuit composed of them according to their principle relationship is called a primary circuit or a primary scheme diagram.

　　為了使一次系統(tǒng)能可靠、穩(wěn)定地運行，隨時監(jiān)視一次系統(tǒng)運行狀態(tài)，同時能隨時控制一次系統(tǒng)所必須配備許多其他電器元件及設(shè)備。

　　In order to ensure the safe, reliable, and stable operation of a primary system, it is necessary to monitor the system's operating status at any time and control it at any time by equipping it with many other electrical components and equipment.

　　如：測量儀表(電流表、電壓表、功率因素表、功率表、頻率表等)、控制信號元件(信號燈、按鈕、轉(zhuǎn)換開關(guān)等)、繼電保護裝置等。由它們按照原理關(guān)系所組成的回路稱為二次回路或二次方案圖。

　　Such as measuring instruments (ammeter, voltmeter, power factor meter, power meter, frequency meter, etc.), control signal components (signal lights, buttons, universal transfer switches, etc.), relay protection devices, etc. The circuit composed of them according to their principle relationship is called a secondary circuit or a secondary scheme diagram.

　　成套設(shè)備主要分為：0.4kV、0.69kV、1.2kV低壓開關(guān)柜;3.6kV、7.2kV、12kV、24kV中壓開關(guān)柜(目前發(fā)展趨勢)、40.5kV高壓開關(guān)柜，動力箱(柜)、照明箱、控制箱(柜、臺)、保護屏、直流屏等。

　　High voltage switchgear: a general term for high-voltage switches mainly used for power generation, transmission, distribution, and energy conversion, as well as control, measurement, protection devices, electrical connections (busbars), enclosures, supports, and other components.

　　開關(guān)柜防護要求中的“五防”：防止誤分誤合斷路器防止帶電分合隔離開關(guān)防止帶電合接地開關(guān)防止帶接地分合斷路器防止誤入帶電間隔。母排位置相序?qū)?yīng)關(guān)系：

　　The "five precautions" in the protection requirements for switchgear: prevent accidental opening and closing of circuit breakers, prevent live opening and closing of isolating switches, prevent live closing of grounding switches, prevent grounded opening and closing of circuit breakers, and prevent accidental entry into live compartments. Corresponding relationship of mother row position and phase sequence:

　　The complete set of equipment is protected by a metal shell (cabinet), which makes it difficult for electrical equipment and current carrying conductors to accumulate dust, making it easy to maintain, especially in areas with external pollution.

　　成套設(shè)備易于實現(xiàn)系列化、標準化、具有裝配質(zhì)量好、速度快、運行可靠性高的特點。由于進行定型設(shè)計和制作生產(chǎn)，所以其結(jié)構(gòu)緊湊、布局合理、縮小了體積和占地面積，降低了造價。

　　The complete set of equipment is easy to achieve serialization, standardization, and has the characteristics of good assembly quality, fast speed, and high operational reliability. Due to standardized design and production, its structure is compact, layout is reasonable, volume and footprint are reduced, and cost is lowered.

　　成套設(shè)備的電器安裝、線路敷設(shè)與變配室的施工是分開進行的，縮短了基建的時間。

　　5、低壓柜母線的計算：

　　5. Calculation of low-voltage cabinet busbar:

　　變壓器上進線及聯(lián)絡(luò)柜三相主母排單拼大約16米(柜寬為800mm時)。當進線柜帶計量時，由于計量互感器及計量表計占用一定的空間致使刀開關(guān)及空氣開關(guān)安裝位置都要下移，故母線長度還應(yīng)加長每相約0.6m;當母線長度大于6m時，母線之間需考慮搭接頭;當母線為雙拼或三拼時，還需考慮墊塊;當進出線電纜較多時應(yīng)考慮橫排出線。

　　The three-phase main busbar of the transformer's incoming line and connecting cabinet is assembled in a single unit for approximately 16 meters (when the cabinet width is 800mm). When the incoming cabinet is equipped with a measuring device, the installation positions of the knife switch and air switch need to be moved down due to the space occupied by the measuring transformer and the measuring meter. Therefore, the length of the busbar should be extended by about 0.6m. When the length of the busbar is greater than 6m, lap joints should be considered between the busbars; When the busbar is double or triple spliced, cushion blocks should also be considered; When there are many incoming and outgoing cables, horizontal outgoing lines should be considered.
