1、选址

1, site selection

低压配电柜的位置应靠近负荷中心，设置在尘埃少、腐蚀介质少、干燥和振动轻微的地方，并宜适当留有发展余地。

Low voltage distribution cabinet should be located close to the load center, located in less dust, less corrosive medium, dry and slightly vibration, and should be properly left room for development.

2、配电线路的布置应符合的条件

2, distribution line layout should meet the conditions

符合场所环境的特征;符合建筑物的特征;人与布线之间可接近的程度;由于短路可能出现的机电应力;在安装期间或运行中布线可能遭受的其他应力和导线的自重。

In accordance with the features of environment; with the building characteristics; accessible degree between the person and the wiring; short-circuit may occur due to mechanical stress; during installation or operation of wiring may suffer from other stress and lead weight.

3、配电线路的布置应避免的外部环境的影响

3, the layout of distribution lines should avoid the influence of external environment

应避免外部热源产生热效应的影响;应防止在使用过程中因水的侵入或因进入团体物而带来的损害;应防止外部的机械性损害而带来的影响;在有大量灰尘的场所，应避免由于灰尘聚集在布线上所带来的影响;应避免由于强烈日光辐射而带来的损害。

Should avoid the impact of external heat source heat effect; should be prevented during use due to water intrusion into the community and or because of damage; should prevent the impact of external mechanical damage; when there is a lot of dust should be avoided because of the dust gathering places, impact on the wiring should be avoided; due to strong solar radiation damage.

4、配电设备的布置

4 、 layout of power distribution equipment

低压配电柜配电设备的布置必须遵循安全、可靠、适用和经济等原则，并应便于安装、操作、搬运、检修、试验和监测。

The layout of power distribution equipment in low voltage distribution cabinet must follow the principles of safety, reliability, applicability and economy, and shall be easy to install, operate, carry, overhaul, test and monitor.

位于同一室内的高压电气设备及低压电气设备间、成排布置的配电柜间都必须留有适当的距离和通道的出口。布置配电设备时应采取必要的安全措施，如有危险电位的裸带电体应加遮护或置于人的伸臂范围之外。当采用遮护物和外罩有困难时，可采用阻挡物进行保护。

All the HV electrical equipment and low voltage electrical equipment in the same room, the arranged distribution cabinets must be provided with proper distance and exit. Layout of distribution equipment should take necessary safety measures, such as bare charged body danger potential should be added in the arm or visor outside the scope. When the baffle and the housing difficulties, the barrier of protection.
