AC fixed (mobile) diesel generator set safety rules

1, the operator passed an examination to obtain operating permits, are allowed to operate, the operator should be familiar with the machine's performance, structure, and to comply with safety and shift system.
2, diesel generator sets to do rain, wind, fire protection facilities, stationary generators work on the ground to keep dry, put the rack pad smooth, well insulated pad; portable generator four tire pressure to meet the requirements and maintain balanced. Installation instrument protection and grounding wire connector, cable, pipeline protection.
3, moving before the inspection or the excitation generator and exciter regulator is normal; sent to gates off the brightest knife, check whether the fuse circuit of each phase. Banned the generator in case of a load start (no backup generators, except self-control).
4, after the diesel engine rated speed, the use of the generator exciter field rheostat resistance decreases the voltage increased to slightly greater than the rated. If the rheostat resistance is zero, there is no voltage, you can add a small amount of load that is able to build pressure. For the use of excitation regulator (harmonic excitation system) can be "automatic - manual" switch on "auto" position that is to build pressure on their own, if stored too long without the generator, the possible loss of field, and can be 6v battery magnetization can build pressure. Switch on "manual" position, the removal of silicon from the excitation circuit, variable reactor in series with the magnetic field around the block, adjust the variable reactance device to adjust the generator voltage.
5, the total transmission gate should be closed, the shunt gates closed one by one, gradually increase the load to the generator, adjust rheostat resistance or reactance device, the generator voltage to maintain ratings.

6, the operation should always monitor their load, temperature, brush work, etc., and should be noted that the increase or decrease with the load, voltage regulation range of variation generally allowed within ± 5%, the frequency of changes does not allow more than ± 1 %. The phase current imbalance, generally should not exceed 10%. Any phase current should not exceed the rating.
7, non-overloading, over-pressure. Prohibit open circuit fuse in one phase of the case to continue transmission. When they find the ground excitation circuit, the rotor winding short circuit, smoke generators, fire and other internal fault occurs, should immediately stop processing.
8, the generator shut down, before subtracting the load gradually until the load is zero, then switch off the main switch and the excitation, the magnetic field into the maximum resistance position, stop the engine. After the winter shutdown, the cooling water tank should put the net (except for filling antifreeze), to prevent cracking caused by diesel engines and other accidents.
9, the phase sequence, voltage and frequency under the same circumstances can be run in parallel, parallel runtime, parallel operations should strictly observe the technical requirements. Closing should be at the same time, has allowed to avoid recoil, burning generators.
10, side by side, and found lost excitation, following a strong spark and brush can not remove the generator out of sync, it should immediately be splitting from the grid generator.
11, tied for the generator shut down before the first load to be transferred to run the generator. Reduced to stop the generator excitation current, and then splitting from the grid, it should be noted without rendering the operation of the generator overload.
12, the generator running, even if that does not increase with voltage excitation also prohibit the repair and maintenance, cleaning work and to touch the high voltage coil.
13, the daily maintenance work should be prepared to achieve neat, clean, lubricate and safe.
