配电箱也叫配电柜,是电动机控制中心的统称。配电箱是按电气接线要求将开关设备、测量仪表、保护电器和辅助设备组装在封闭或半封闭金属柜中或屏幅上,构成低压配电装置。

配电箱是数据上的海量参数,一般是构成低压林按电气接线,要求将开关设备、测量仪表、保护电器和辅助设备组装在封闭或半封闭金属柜中或屏幅上,构成低压配电箱。正常运行时可借助手动或自动开关接通或分断电路。

合理的分配电能,方便对电路的开合操作。有较高的安全防护等级,能直观的显示电路的导通状态。

配电箱构成主要分为两部分,一是成套部件,即配电箱外壳及其相关配件。二是电气元件及相关附件,即空气开关和其所需要的附件。柜内有以下各部分组成一、断路器断路器:既开关,是配电柜的主要元器件,常用的有空气开关、漏电开关、双电源自动转换开关。

Distribution box, also known as distribution cabinet, is the general term of motor control center. The distribution box is to assemble the switchgear, measuring instruments, protective appliances and auxiliary equipment in the closed or semi closed metal cabinet or panel according to the electrical wiring requirements to form a low-voltage distribution device.

The distribution box is a mass of data parameters, which generally constitutes a low-voltage forest. According to the electrical wiring, the switchgear, measuring instruments, protective appliances and auxiliary equipment are required to be assembled in a closed or semi closed metal cabinet or screen to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switch.

Distribute electric energy reasonably to facilitate the opening and closing operation of the circuit. It has high safety protection level and can intuitively display the conduction state of the circuit.

The composition of the distribution box is mainly divided into two parts. One is the complete set of components, that is, the shell of the distribution box and its related accessories. The second is the electrical components and related accessories, that is, the air switch and its required accessories. The cabinet is composed of the following parts: 1. Circuit breaker circuit breaker: switch, which is the main component of the distribution cabinet. Commonly used are air switch, leakage switch and dual power automatic transfer switch.

The distribution box is a low-voltage distribution box composed of switchgear, measuring instruments, protective appliances and auxiliary equipment assembled in a closed or semi closed metal cabinet or screen according to the electrical wiring requirements. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switch. In case of fault or abnormal operation, cut off the circuit or give an alarm with the help of protective appliances. The measuring instrument can display various parameters in operation, adjust some electrical parameters, and prompt or send signals for deviation from the normal working state.
