发动机组使用在操作时需要注意什么?

来源:   发布于:2018-05-31

1、对于新的或者是长期没有使用的发电机组在进入正常运行之前,一定要经过检查,尤其是要检查绕接线的情况、组绝缘的情况,如果有异样,必须立刻进行处理。

1, for the new or long - term non - use generator before entering the normal operation, it must be checked, especially to check the situation of the wiring, the condition of the group insulation, if there is a difference, it must be processed immediately.

2、发电机组发动后要慢慢的提高转速,要在经过检查确认所有情况都完好的前提下才可以进行低速到额定转速的空载运行,空载运行的时候,重点检查机油压力,是否有异响,励磁电流、三相电压变化等,如果有异常情况必须立即停机进行检查,了解情况后再发动,如果,机组正常的话就可以直接进入到正常运行中,工作人员要严密监视控制屏上的仪表的变化情况,是否在许可范围并作相应的调整。

2, after the generator set to start slowly to improve the speed, should be checked and confirmed that all conditions are well under the premise that the low speed to the rated speed of the no-load operation, when no load operation, key inspection oil pressure, whether there is abnormal noise, excitation current, three phase voltage changes, if there is an abnormal condition must Immediately stop to check, understand the situation and restart, if, if the unit is normal, you can directly enter the normal operation, the staff should closely monitor the change of the instrument on the control screen, whether in the license scope and make the corresponding adjustment.

3、操作时,工作人员要和带电设备保持一个安全的距离并且穿戴好劳动防护装备,倒闸操作时要注意先后顺序,停电的时候先断开各个支脉的开关然后再断开总开关之后再进行四极双投刀闸切换位置,送电的时候,顺序相反进行,正常停机要先卸掉部分负载再断总开关,最后关柴油机,不可以不拉断总开关,随着发电机组熄火而自行停电,停机后对机组作常规性检查,并记录运行情况

3, in the operation, the staff should keep a safe distance from the live equipment and wear good labor protection equipment. When the switching operation is done, we should pay attention to the sequence. When the power outage, the switch of each branch is broken and then the total switch is disconnected, then the position of the four pole double cast knife sluice is changed. When the power is sent, the order is in reverse order. Yes, the normal shutdown should first unload part of the load and then break the total switch, finally close the diesel engine, can not break the total switch, with the generator set out of the power stop, after the shutdown of the unit for routine inspection, and record the operation situation.

4、要是发生工作人员触电的情况,必须立刻切断电源开关或者是用绝缘器具快速使电源断掉或脱离电源,然后再进行抢救并请医生来现场抢救,万一遇有电气设备遇到水灾时,必须马上去把所有电源切断并告知当地供电所然后进行救火,对带电设备救火要

4, if an electric shock occurs, the power switch must be cut off immediately or the power is quickly broken off or out of the power supply with an insulating device. Then, rescue and ask the doctor to rescue it. In case of a flood, the power supply must be cut off and informed of the local power supply. To save fire and to save fire for live equipment

使用干式灭火器、二氧化碳灭火器等,不可以用水。以上就是发电机组在使用的过程中需要注意到的几点。

Use dry fire extinguishers, carbon dioxide fire extinguishers, etc. These are the points that need to be noticed in the process of generating units.
