三、交、直流配電說明
III. Instructions for AC/DC Power Distribution System

整車配電系統(tǒng)由交流和直流兩大部分構成，通過配電控制盤（ 配電盤）進行控制和監(jiān)測。
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：柴油發(fā)電機、雙電源自動切換、UPS、小型斷路器等組成。
1. The AC part includes: diesel generator, dual power auto switch, UPS, miniature circuit breaker (MCB), etc.
市電（220V50HZ）經電纜盤連接器，接入車內交流配電盤，閉合市電總開關后 ，進入雙電源自動切換，市電和發(fā)電機在此進行轉換（默認市電優(yōu)先）。分成兩路，一路通過小型斷路器直接控制用電設備。一路通過UPS，及（UPS,旁通）轉換開關，小型斷路器去控制用電設備。整個配電系統(tǒng)，主要以小型斷路器作為設備的過載保護。
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.

See the AC Power Distribution Schematic Diagram for details.

2，直流部分由充電機和電瓶組成。直流電源來自附加電瓶，直接接入直流配電盤，通過直流配電盤的電磁總開關來作為電瓶的欠壓保護，在通過小型斷路器來控制用電設備。同樣以小型斷路器作為設備的過載保護。
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.
