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電氣成套設備，其實這種叫法是不準確的，學名應該是“成套配電裝置”。那么開關柜為什么叫“成套配電裝置”？下面小編為您講解：

The common low-voltage distribution cabinet and high-voltage distribution cabinet are not only the distribution cabinet itself, but actually the electrical complete set of equipment we commonly call. In fact, this name is inaccurate, and the scientific name should be "complete set of power distribution device". So why is the switch cabinet called "complete power distribution device"? The following editor will explain to you:

成套配電裝置是以斷路器為主的電氣設備，成套配電裝置是制造廠成套供應的設備，由制造廠預先按照主接線的要求，將每一回路的電氣設備高低壓電器(包括控制電器、保護電器、測量電器、如斷路器、隔離開關、互感器等)以及母線、載流導體、絕緣子等，裝配在封閉或半封閉的金屬柜中，構成各單元電路分柜，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，就構成整個配電裝置。

The complete set of power distribution device is the electrical equipment mainly based on the circuit breaker. The complete set of power distribution device is the equipment supplied by the manufacturer in a complete set. The manufacturer assembles the high and low voltage electrical equipment (including control electrical equipment, protection electrical equipment, measuring electrical equipment, such as circuit breaker, disconnector, mutual inductor, etc.), bus, current-carrying conductor, insulator, etc. of each circuit in a closed or semi-closed metal cabinet according to the requirements of the main wiring in advance, Each unit circuit sub-cabinet forms a complete set of power distribution device. During installation, each unit and sub-cabinet (also called bay) are combined according to the main wiring mode to form the whole power distribution device.

在電器成套設備中把母線、隔離開關(高壓)、刀開關(低壓)、斷路器(空氣開關)、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)、避雷器等組成的設備叫一次設備。由它們按照原理關系所組成的回路稱為一次回路或一次方案圖。

In the complete set of electrical equipment, the equipment consisting of bus, disconnector (high voltage), knife switch (low voltage), circuit breaker (air switch), voltage transformer, current transformer, power transformer, AC contactor, protective relay (thermal relay), lightning arrester, etc. is called primary equipment. The circuit composed of them according to the principle relationship is called primary circuit or primary scheme diagram.

為了使一次系統能可靠、穩定地運行，隨時監視一次系統運行狀態，同時能隨時控制一次系統所必須配備許多其他電器元件及設備。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、轉換開關等)、繼電保護裝置等。由它們按照原理關系所組成的回路稱為二次回路或二次方案圖。

In order to ensure the safe, reliable and stable operation of the primary system, monitor the operation status of the primary system at any time, and control the primary system at any time, many other electrical components and equipment must be equipped. Such as measuring instruments (ammeter, voltmeter, power factor meter, power meter, frequency meter, etc.), control signal elements (signal lamp, button, universal transfer switch, etc.), relay protection devices, etc. The circuit composed of them according to the principle relationship is called secondary circuit or secondary scheme diagram.

成套配電裝置的特點

Characteristics of complete power distribution device

1、成套設備有金屬外殼(柜體)的保護，電氣設備和載流導體不易積灰，便于維護，特別是對外處的污穢地區時更為突出。

1. The complete set of equipment is protected by a metal shell (cabinet). The electrical equipment and current-carrying conductor are not easy to accumulate dust and are easy to maintain, especially in the external polluted areas.

2、成套設備易于實現系列化、標準化、具有裝配質量好、速度快、運行可靠性高的特點。由于進行定型設計和制作生產，所以其結構緊湊、布局合理、縮小了體積和占地面積，降低了造價。

2. The complete set of equipment is easy to realize serialization and standardization, and has the characteristics of good assembly quality, fast speed and high operation reliability. Due to the finalization design and production, the structure is compact, the layout is reasonable, the volume and floor area are reduced, and the cost is reduced.

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

3. The electrical installation of the complete set of equipment, the line laying and the construction of the transformation and distribution room are carried out separately, which shortens the time of capital construction.
