Isolate Inverter 隔离逆变器


For certain faults the inverter is inhibited and isolated until a reset occurs 某些故障将禁止和隔离直至复位 – Inhibit Inverter IGBTs – 禁止逆变器IGBTS – Open HSCB, LC, CCC and discharge filter – 打开HSCB,LC,CCC并放电 – Send signal to TIMS when LC and CCC are proved open (L_NLCC high and L_CCCC low) – 当LC和CCC断开时，相关信号送至TIMS Reset depends on whether isolation is due to a HSCB self trip (excessive current) or another fault 复位取决于隔离是由于HSCB跳闸或其他故障 HSCB self trip HSCB跳闸 – PCE will attempt to reset automatically – PCE将尝试自动复位

General description of Fault Handler 故障处理器
Principle functions 功能
• • • • • • Initially PCE isolates HSCB 起初PCE隔离HSCB After 30s delay PCE automatically attempts to re-close HSCB 30秒后，PCE自动尝试闭合HSCB If HSCB self trips again PCE locks out 若HSCB再跳闸，PCE封锁

Lock Out Inverter 封锁逆变器


Inverter is isolated AND LC and CCC prevented from reclosing until reset command received from maintenance PC 逆变器隔离，LC和CCC不会再闭合直至PC发出复位指令

– If not HSCB and LC are commanded open – 如果未关闭，HSCB和LC将打开

Establish event/fault type 建立事件/故障类型


PCE must identify event type so that the required actions to protect the power circuit can be carried out PCE必须区分事件类型，以采取相应的动作保护功率回路 An ‘event’ does not require any power circuit protection, but should be logged 一个事件无需任何保护动作，但应当被记录

Remainder of propulsion system remains operational 注意，牵引系统仍将工作 Certain faults require the electric brake to be locked out until a manual reset occurs (switch battery supply off then on, or reset command from maintenance PC) 一些故障将封锁电制动，直至手动复位（开关电源或PC设 置）
Other faults 其他故障 – PCE remains isolated until zero speed and reset command received from maintenance PC – PCE保持隔离状态直至零速，并由PC发出复位指令 SHL1.2Ex. Training 2006 11
