主配电板试验程序

1、1. Insulation resistance test绝缘电阻试验The insulation resistance between bus-bar to earth and the resistance between bus-bars (include 220Vpanel) each phase, shall be measured by a DC 500V megger. Test to be before and after continuous load test.在所有主配电板的开关及保险丝处于断开位置时，用直流500伏兆欧表测量汇流排对地的绝缘电阻，及汇流排（包括220V屏）

2、各相之间绝缘电阻。2. Reverse power relay trip test逆功率继电器脱扣试验Reverse power relay must delay act correctly, the ACB break delay. Reverse power setting: 10% rated power (70kW) Setting time: 10 secondsThe result of test should be recorded into the No.1 tables.逆功率继电器必须正确延时动作，空气短路延时断开。逆功率设定值：10%额定功率（70KW）设定时间：105%

3、(472.5V) delay 10 second alarm, trip, stand-by generator start and switch on. 汇流排电压高105%(472.5V)以上，延时10秒报警，脱扣，备用机起 动并合闸。 （b）Bus voltage low 95% (427.5V) delay 10 seconds alarm, trip, stand-by generator start and switch on 汇流排电压低95% (427.5V)以下，延时10秒报警，脱扣，备用机起 动合闸。 （c） Frequency low 105%(63Hz) 10 seco

4、nds alarm,trip, stand-by generator start and switch on 频率高105%(63Hz)以上，延时10秒报警，脱扣，备用机组起动合闸。 （e）Bus no-voltage (main power failure) stand-by generator start and switch on 汇流排失压（全船失电）备用起动并合闸 （f） General alarm trip and emergency stop 公共报警 脱扣并紧急停车 （g） Start failure alarm 起动故障 报警（3） When three generators

5、 running at automatic mode, two running in parallel and another set is stand-by. If any of the running generators trip, the stand-by set shall start automatically and running in parallel, the failure generator quit running. 三台发电机自动模式时，二台并联运行，另一台作备用发电机，当任何一台运行中的发电机故障脱扣，备用机组自动起动，并联运行，故障机退出运行。（4） Runni

6、ng in parallel automatically and switchover automatically test. 自动并联运行和自动切换运行试验This test is carried out refer to “the process chart of generator control” and verify good programming control and following function control. 可参照“发电机控制流程图”所示的控制程序进行，并验证良好的程序控制和下列控制功能。 （a）Generator start automatically 发电机

7、自动起动 （b）Automatic synchronization 自动同步 （c）During the period of parallel running the loads shall be distributed automatically 并联运行期间的自动负荷分配 （d）During the period of generators changing the loads shall be transfer automatically 发电机转换期间的自动负荷转移 （e）When the net power exceed power of single generator 90% v

8、ia automatic load detection, the stand-by generators shall started delay 10 sec and then running. 通过自动负荷检测，当网上功率超过单机功率的90%时，备用机组延时10秒起动并投入 （f）Two sets of generators run in parallel, when the total loads is under single power 70%, loads shall be shifted to one generator automatically after 5 minute c

9、ontinuously running, the other generator disconnected automatically and shut down delay under no-load condition. 二台并联运行时，若总负荷为单机功率的70%以下时，持续5分钟后负荷自动转移至一台发电机，另一台发电机自动分闸后空载停车（5） MSB safety protection alarm see No.4 tables. 主配电板安全保护报警点见表格4。Test of reverse power(cos=1.0)逆功率试验（Table1 表1）Generator发电机TestO
