Four points to know when using new or overhauled generator sets:

 

1. Before entering normal operation, new or long-unused generator sets must be inspected, especially the condition of winding and insulation. If there is any abnormality, it must be handled immediately.

 

2. After the generator set is started, the speed should be slowly increased. The no-load operation from low speed to rated speed can be carried out only after all conditions are checked and confirmed to be in good condition. During the no-load operation, the oil pressure, whether there is abnormal noise, excitation current, three-phase voltage change, etc. should be checked. If there is any abnormal condition, the generator must be stopped immediately for inspection, and the engine can be started after understanding the situation. If, If the unit is normal, it can directly enter the normal operation. The staff should closely monitor the change of the instrument on the control panel to see if it is within the permitted range and make corresponding adjustments.

 

3. During operation, the staff should keep a safe distance from the live equipment and wear labor protection equipment. During switching operation, attention should be paid to the sequence. In case of power failure, first disconnect the switches of each branch, then disconnect the main switch, and then carry out the four-pole double-switch switch switching. During power transmission, the sequence is reversed. During normal shutdown, first remove part of the load, then disconnect the main switch, and finally turn off the diesel engine, It is not allowed to cut off the main switch and cut off the power automatically with the generator unit flameout. After shutdown, conduct routine inspection on the unit and record the operation condition

 

4. In case of electric shock of the staff, the power switch must be cut off immediately or the power supply must be quickly cut off or separated from the power supply with insulating apparatus, and then the rescue must be carried out and the doctor should be sent to the scene for rescue. In case of a flood of electrical equipment, all electrical sources must be cut off immediately and the local power supply station must be informed, and then the fire fighting must be carried out for the live equipment
