常见的低压配电柜、高压配电柜其实并不是单单指配电柜本身，它实际上是我们俗称的成套设备，其实这种叫法是不准确的，学名应该是“成套配电装置”。

　　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".

　　那么什么是成套配电装置，它有哪些特点呢?

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

　　什么是“成套配电装置”?开关柜(又称成套开关或成套配电装置)，它是以断路器为主的电气设备;成套配电装置是制造厂成套供应的设备，由制造厂预先按照主接线的要求，将每一回路的电气设备高低压电器(包括控制电器、保护电器、测量电器、如断路器、隔离开关、互感器等)以及母线、载流导体、绝缘子等，装配在封闭或半封闭的金属柜中，构成个单元电路分柜，此单元电路分柜成为成套配电装置。安装时，按主接线方式，将各单元分柜(又称间隔)组合起来，就构成整个配电装置。

　　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.

　　在电器成套设备中把母线、隔离开关(高压)、刀开关(低压)、断路器(空气开关)、电压互感器、电流互感器、电力变压器、交流接触器、保护继电器(热继电器)、避雷器等组成的设备叫一次设备。由它们按照原理关系所组成的回路称为一次回路或一次方案图。

　　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.

　　为了使一次系统能可靠、稳定地运行，随时监视一次系统运行状态，同时能随时控制一次系统所必须配备许多其他电器元件及设备。

　　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：测量仪表(电流表、电压表、功率因素表、功率表、频率表等)、控制信号元件(信号灯、按钮、转换开关等)、继电保护装置等。由它们按照原理关系所组成的回路称为二次回路或二次方案图。

　　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.

　　成套设备主要分为：0.4kV、0.69kV、1.2kV低压开关柜;3.6kV、7.2kV、12kV、24kV中压开关柜(目前发展趋势)、40.5kV高压开关柜，动力箱(柜)、照明箱、控制箱(柜、台)、保护屏、直流屏等。

　　The complete set of equipment is mainly divided into: 0.4kV, 0.69kV, 1.2kV low-voltage switchgear; 3.6kV, 7.2kV, 12kV, 24kV medium voltage switchgear (current development trend), 40.5kV high voltage switchgear, power box (cabinet), lighting box, control box (cabinet, platform), protection screen, DC screen, etc.

　　高压开关设备：主要用于发电、输电、配电和电能转换的高压开关以及和控制、测量、保护装置、电气联结(母线)、外壳、支持件等组成的总称。

　　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.

　　开关柜防护要求中的“五防”：防止误分误合断路器防止带电分合隔离开关防止带电合接地开关防止带接地分合断路器防止误入带电间隔。母排位置相序对应关系：

　　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:

　　防护等级：外壳、隔板及其他部分防止人体接近带电部分和触及运动部件以及防止外部物体侵入内部设备的保护程度。

　　Protection level: The degree of protection provided by the shell, partition, and other parts to prevent human access to live parts and moving parts, as well as to prevent external objects from entering internal equipment.

　　成套配电装置的特点

　　Characteristics of complete power distribution equipment

　　成套设备有金属外壳(柜体)的保护，电气设备和载流导体不易积灰，便于维护，特别是对外处的污秽地区时更为突出。

　　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.

　　成套设备易于实现系列化、标准化、具有装配质量好、速度快、运行可靠性高的特点。由于进行定型设计和制作生产，所以其结构紧凑、布局合理、缩小了体积和占地面积，降低了造价。

　　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.

　　成套设备的电器安装、线路敷设与变配室的施工是分开进行的，缩短了基建的时间。

　　The electrical installation, line laying, and construction of the transformer room for the complete set of equipment are carried out separately, which shortens the construction time.

　　Based on the drawings provided by the user, first check the directory of the drawings and then assign and classify them. Understand the design intention of this project according to the design specifications and technical requirements (for those with bidding documents, it is also necessary to combine the technical requirements of the bidding documents), consider calculating the price required for variable schemes, and pay attention to the floor plan (which reflects whether there is a busbar bridge between cabinets and the length of the busbar bridge).

　　2、相关注意事项：

　　2. Related precautions:

　　(1)就高压柜而言，为了满足五防要求，进线柜需配带电显示器(强制型：DXN-10、24/35Q)及电磁锁，出线柜需配带电显示器(提示型：DXN-10/35T)及接地开关联锁装置。

　　5、低压柜母线的计算：

　　5. Calculation of low-voltage cabinet busbar:

　　变压器上进线及联络柜三相主母排单拼大约16米(柜宽为800mm时)。当进线柜带计量时，由于计量互感器及计量表计占用一定的空间致使刀开关及空气开关安装位置都要下移，故母线长度还应加长每相约0.6m;当母线长度大于6m时，母线之间需考虑搭接头;当母线为双拼或三拼时，还需考虑垫块;当进出线电缆较多时应考虑横排出线。

　　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.
