☻6 Switching room?配电小间内有什么?
(1) Concept :
在电气竖井内，如果除敷设干线回路外，还设置各 层的电力、照明分配电箱及弱电设备的端子箱等电 气设备，则称为电气小间。
(2) Characteristics:
◆竖井的一部分 ◆每个楼层上都有
◆每层均设向外开的小门
☻6 Switching room? What’s inside?
• Under 60m2: 4~5kW； • 60m2~100m2:5kW~6kW ； • 100m2:8kW~12kW； • 150m218~20kW ★ Requirement • Single-phase for 8kW and below. • Three-phase for over 8kW.

Voltage Dependent Resistor
RCD
A residual-current device (RCD), or residual-current circuit breaker (RCCB) is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized (line) conductor (s) and the return (neutral) conductor. In normal circumstances, these two wires are expected to carry matching currents, and any difference usually indicates a short circuit . A current of around 30mA (0.030 Amps) is potentially sufficient to cause cardiac arrestor serious harm if it persists for more than a small fraction of a second. RCD are designed to disconnect the conducting wires quickly enough to prevent serious injury from such shocks. (This is commonly described as the RCD being "tripped".)
• 电气竖井就是从建筑物的底层到顶层留出的一条井道。 竖井在每个楼层设有配电小间，每层都有楼板隔开，只留 出不同尺寸的孔洞

◆ Path: for heavy and light current wires
◆Wiring:竖井内可采用金属管、金属线槽、 电缆、电缆桥架和封闭母线
◆ Types:有强电井、弱电井，也有强弱结合，
这时强弱电干线之间采取隔离措施，以免干 扰。
