如何使用柴油发电机组 How to use a diesel generator set

一、     普通柴油发电机组

通称“手启动”机组配电瓶。打开电钥匙，手动按钮立即启动，调整油机到额定转速，稳定后检查柴油机的油水数据后可合闸送电。送电时间看人员操作熟练和机组调整的状况。

二、     普通自动化柴油发电机组

自动化包含自启动、自停机、自保护。有低油压、高水温、超转速、过、欠压、过电流保护装置。发电机组配备启动电瓶，并连接好后，柴油发电机组处于待命状态。当市电失电，机组立即启动（0—15秒可调）到额定转速。并稳定在额定转速，相应的指标达标。手动合闸送电，反之市电得电后手动分闸自动停机（3分钟内），机组处于待命状态。这样，往返循环。

三、     自启动、自切换

机组配电瓶用于启动含有普通自动化柴油发电机组保护功能外，还具有监测市电功能。当市电失电、断相、欠压、过压。欠频、过频相序反时，立即启动柴油发电机组，并在机组达到正常运行状态后立即启动（可调），自动将切换开关，从市电侧切换到发电机组侧，正常供电。反之当市电恢复正常，切换开关自动立即切换到市电侧，同时柴油发电机组经若干秒（0—9999秒可调），空车运行3—5分钟停机。

1、 Ordinary diesel generator set

Commonly known as "manual start" units with batteries. Turn on the electric key, press the manual button to start immediately, adjust the oil engine to the rated speed, and after stabilizing, check the oil and water data of the diesel engine before closing and powering on. The power transmission time depends on the proficiency of personnel and the adjustment of the unit.

2、 Ordinary automated diesel generator set

Automation includes self start, self stop, and self protection. There are low oil pressure, high water temperature, overspeed, overvoltage, undervoltage, and overcurrent protection devices. The generator set is equipped with a starting battery, and once connected, the diesel generator set is in standby mode. When the mains power fails, the unit immediately starts (adjustable from 0-15 seconds) to the rated speed. And stabilize at the rated speed, with corresponding indicators meeting the standards. Manually close the switch for power transmission, otherwise manually open the switch and automatically shut down (within 3 minutes) after the mains power is supplied, and the unit is in standby mode. In this way, there is a round trip loop.

3、 Self starting and self switching

The unit is equipped with a battery for starting the ordinary automated diesel generator set protection function, and also has the function of monitoring the mains power. When the mains power loses power, loses phase, experiences undervoltage, or overvoltage. When the phase sequence of under frequency and over frequency is reversed, immediately start the diesel generator set and start it immediately (adjustable) after the unit reaches normal operating state. The switch will automatically switch from the mains side to the generator set side for normal power supply. On the contrary, when the mains power returns to normal, the switch will automatically switch to the mains side, and the diesel generator set will stop running empty for 3-5 minutes after a few seconds (adjustable from 0-9999 seconds).
