What Are the Safety Precautions for Diesel Generators
by Starlight Generator dieselgeneratortech1. The diesel engine-powered
generator, the operation of engine section is carried out in accordance with
the relevant regulations of the internal combustion engine.
2. Before starting the generator,
it is necessary to carefully check whether the wiring of each part is correct,
whether the joint parts are firm, whether the brush is normal, whether the
pressure meets the requirements, and whether the grounding wire is good.
3. Before starting, put the
resistance of the field varistor at the maximum position, disconnect the output
switch, and the generator set with the clutch should disengage the clutch.
Start the diesel engine with no load, and then start the generator after
running smoothly.
4. After the generator starts running, always pay attention to whether there is mechanical noise or abnormal vibration. After confirming that the situation is normal, adjust the generator to the rated speed, adjust the voltage to the rated value, and then close the output switch to supply power. The load should be gradually increased to strive for three-phase balance.
5. The parallel operation of the
generator must meet the same frequency, the same voltage, the same phase, and
the same phase sequence.
6. Generators that are to be
operated in parallel must have entered into normal and stable operation.
7. After receiving the signal of
“preparing for parallel connection”, the whole unit shall be used as the
standard to adjust the speed of the diesel engine and close at the synchronous
moment.

8. Generators operating in parallel should adjust the load reasonably and distribute the active power and reactive power of each generator in a balanced manner. The active power is regulated by the diesel throttle and the reactive power is regulated by the excitation.
9. The generator in operation
should pay close attention to the engine sound and observe whether the
indication of various instruments is within the normal range. Check if the
running part is normal and the generator temperature rise is too high. And make
a good record of the operation.
10. When parking, reduce the
load, restore the excitation varistor, reduce the voltage to the minimum, then
cut off the switch in sequence, and finally stop the diesel engine.
11. If the diesel engine in
parallel operation needs to stop one due to load drop, the load of one
generator that needs to be parked should be transferred to the running
generator, and then stopped by the method of single generator parking. If all
parking is required, the load will be cut off first, and then the single
generator will be shut down.
12. Mobile generators must be
parked on a stable foundation before use. No movement is allowed when running.
13. When the generator is
running, it should be considered to have voltage even if it is not excited. It
is forbidden to work on the rotating generator lead-out line and touch the
rotor or clean it by hand. Generators in operation must not be covered with
canvas or other objects.
14. After the diesel generator is
overhauled, it is necessary to carefully check whether there are tools,
materials and other debris between the rotor and the stator slot to avoid
damage to the generator during operation.
15. All electrical equipment in
the machine room must be grounded reliably.
16. It is forbidden to pile up
sundries and flammable and explosive materials in the engine room. Except for
the on-duty personnel, other personnel are prohibited from entering without
permission.
17. The necessary fire-fighting equipment shall be provided in the machine room. When a fire accident occurs, the power shall be stopped immediately, the generator shall be turned off, and the fire extinguisher of carbon dioxide or carbon tetra-chloride shall be used for the rescue.
