配電櫃是企業生產、辦公的供電設備。它主要分為高壓開關櫃和低壓配電櫃。配電櫃種類繁多，以下是一些常見的類型：
Switchgear is the power supply equipment for enterprises' production and office. It is mainly divided into high-voltage switchgear and low-voltage switchgear. There are many types of switchgear and here are some common types:
按用途分類：
According to the purpose classification:
進線櫃：主要用於接收來自電網的電能，一般安裝有斷路器、隔離開關等，對進線電源進行控制和保護。例如在一個工廠的供電系統中，進線櫃接收來自變電站的高壓電。
Incoming cabinet: Mainly used to receive power from the power grid, generally equipped with circuit breakers, disconnectors, etc., to control and protect the incoming power supply. For example, in the power supply system of a factory, the incoming cabinet receives high-voltage electricity from the substation.
出線櫃：是將經過配電櫃分配後的電能輸送到各個用電設備或支路的櫃子。它可以爲不同的負載，如電機、照明等電路提供合適的電能輸出，內部也配備有相應的保護裝置。
Outgoing cabinet: It is the cabinet that transports the power distributed through the switchgear to various electrical equipment or branches. It can provide suitable power output for different loads, such as motor, lighting and other circuits, and is also equipped with corresponding protection devices inside.
計量櫃：專門用於電能計量的配電櫃。內部裝有電度表、互感器等計量設備，能夠準確測量使用者的用電量，常見於需要精確計量電能消耗的場所，如商業寫字樓的配電室。
Metering cabinet: A switchgear to power metering. It is equipped with watt-hour meters, transformers and other metering equipment inside, which can accurately measure the electricity consumption of users, and is commonly seen in places that require accurate measurement of power consumption, such as the power distribution room of a commercial office building.
補償櫃：用于無功補償，提高電網的功率因數。其內部有電容器、電抗器等設備。當電網中的感性負載較多時，補償櫃可通過投入適當的電容來減少無功功率的傳輸，降低線路損耗，壹般工業企業等用電量大且感性負載多的地方會使用。
Compensation cabinet: Used for reactive power compensation to improve the power factor of the power grid. It has equipment such as capacitors and reactors inside. When there are more inductive loads in the power grid, the compensation cabinet can reduce the transmission of reactive power by putting in appropriate capacitors, reduce line losses, and is generally used in places with large electricity consumption and more inductive loads, such as industrial enterprises.
按電壓等級分類：
According to the voltage level classification:
高壓配電櫃：通常適用於電壓等級在 3kV 及以上的電網。例如 10kV 的高壓配電櫃在城市的配電網中廣泛應用於向小區、工廠等分配電能，內部的電氣設備絕緣要求高，結構設計更注重安全距離和滅弧能力。
High-voltage switchgear: Usually applicable to power grids with a voltage level of 3kV and above. For example, a 10kV high-voltage switchgear is widely used in urban distribution networks to distribute power to residential areas, factories, etc. The electrical equipment inside has high insulation requirements, and the structural design pays more attention to the safety distance and arc extinguishing ability.
低壓配電櫃：電壓等級一般為 0.4kV 及以下。常見於建築物內的配電室，為照明、插座、電梯等低壓用電設備供電，內部電器元件相對緊湊，操作和維護相對簡單。
Low-voltage switchgear: The voltage level is generally 0.4kV and below. Commonly found in the power distribution room of a building, it supplies power to low-voltage electrical equipment such as lighting, sockets, elevators, etc. The internal electrical components are relatively compact, and the operation and maintenance are relatively simple.
按結構形式分類：
According to the structural form classification:
固定式配電櫃：其內部的電器元件和設備都是固定安裝的。這種配電櫃結構簡單、成本較低，但靈活性較差，後期如果需要對內部電路進行改造或擴充，操作較為複雜，常用於對電氣系統變動需求較小的場所。
Fixed switchgear: The electrical components and equipment inside are fixedly installed. This type of switchgear has a simple structure and low cost, but the flexibility is poor. If it is necessary to reform or expand the internal circuit in the later stage, the operation is more complicated, and it is commonly used in places with less demand for changes in the electrical system.
抽屜式配電櫃：電器元件安裝在抽屜式的單元中，可以方便地抽出和插入。這種結構方便檢修和維護，當某個迴路出現故障時，可以快速抽出相應抽屜進行檢修，而不影響其他迴路的正常運行，廣泛應用於對供電可靠性和可維護性要求較高的場所，如醫院、資料中心等。Drawer-type switchgear: Electrical components are installed in drawer-type units and can be easily pulled out and inserted. This structure is convenient for maintenance and repair. When a circuit fails, the corresponding drawer can be quickly pulled out for maintenance without affecting the normal operation of other circuits. It is widely used in places with high requirements for power supply reliability and maintainability, such as hospitals, data centers, etc.
