Emergency Diesel Engine
Generator
应急发电机
Before and after the load test, the
insulation measurement to be carried out for
all electrical equipment that this test
concerns such as alternators and heaters
负载试
验前后应测量相关设备的绝缘，如发电机和加热器。
1. Alarm function
报警功能
Check and
adjust the set value of pressure switches for
alarm of lub. oil low
pressure by
manually operated hydraulic pump. Check and adjust
the set value of
temperature switches
for alarm of cooling water high temperature and
high
temperature by means of heating.
Check the indication function of alarm on control
box at the engine while set the value
of alarm. And check the proper function of
general alarm of emergency generator in
monitoring system of ECR.
用手摇
液压泵校对并调定滑油低压报警压力开关的调定值。用加热法校对
并调定冷却水高温及滑
油温度高报警温度开关调整值。整定报警值同时，检查
机旁控制箱上报警显示功能，并检
查集控室内监控系统的应急发电机总故障报
警功能
.
2. Safety protection
安全保护功能
Make diesel generator over speed by
artificial actuation. Check the function of
over speed and alarm for the stop by
over speed. Over speed test carried out under
no load condition.
人为造成柴油机超速
，检查超速功能，同时检查超速停车报
警功能。超速试验在没有负荷的状态下进行。

4. starting of emergency
generator.
应急发电机的启动试验
emergency generator in cold condition.
Check that it is stable and reliable
冷态启动应急发电机，检查启动是否平稳可靠
test and start fail alarm test with the first
power source (battery).
第一能源（蓄电池）启动试验和启动失败报警试验
4.2.1. Charged batteries in sufficient
time, start the diesel generator 3 times in cold
condition without recharging.
启动蓄电池充电之后，
中途不补充充电的情况下，
应能保证
冷态启动柴油机
3
次。
电瓶电压

4.2.2. Make diesel
generator fail to start 3 times by cutting off
F.O. supply and giving
alarm
by the “START
FAILURE” on
control panel.
用切断燃油供给的方法使柴油发动机
3
次启动失败，
在控制板上来
“
START

”报警。
4.3 Check
reliability of the function for second power
source (spring start motor). Start
the
generator when cold with hand spring start motor
no less than three times within
thirty
minutes.
检查弹簧启动马达功能是否可靠（冷态）
，在
30
