三、交、直流配电说明
III. Instructions for AC/DC Power Distribution System

整车配电系统由交流和直流两大部分构成，通过配电控制盘（ 配电盘）进行控制和监测。
Power distribution system of the vehicle consists of two major parts: AC and DC, which are controlled and monitored by the power distribution and control panel (switchboard).
1，交流部分包括：柴油发电机、双电源自动切换、UPS、小型断路器等组成。
1. The AC part includes: diesel generator, dual power auto switch, UPS, miniature circuit breaker (MCB), etc.
市电（220V50HZ）经电缆盘连接器，接入车内交流配电盘，闭合市电总开关后 ，进入双电源自动切换，市电和发电机在此进行转换（默认市电优先）。分成两路，一路通过小型断路器直接控制用电设备。一路通过UPS，及（UPS,旁通）转换开关，小型断路器去控制用电设备。整个配电系统，主要以小型断路器作为设备的过载保护。
Mains supply (220V 50HZ) is connected to the on-board AC switchboard via cable reel connector and enters the dual power auto switch after the mains master switch is closed; the mains supply and the generator are converted here (mains supply first by default). The power supply is split into two ways: one way to directly control the electric equipment via MCB while the other to control the electric equipment via UPS, (UPS bypass) change-over switch and MCB. MCB is used as the main overload protection device of the whole power distribution system.
具体细节参见交流配电原理图。

2，直流部分由充电机和电瓶组成。直流电源来自附加电瓶，直接接入直流配电盘，通过直流配电盘的电磁总开关来作为电瓶的欠压保护，在通过小型断路器来控制用电设备。同样以小型断路器作为设备的过载保护。
2. The DC part is comprised of charger and battery. DC power comes from the additional battery and directly enters the DC switchboard. It uses the electromagnetic master switch of the DC switchboard as under-voltage protection device of the battery and controls the electric equipment by MCB. Likewise, MCB is used as the main overload protection device of the equipment.
具体细节参见直流配电原理图。
