Pay attention to fire prevention when using Yuchai diesel generator sets
When using Yuchai diesel generator sets, we must also pay attention to the work of fire prevention. What are the specific tasks to be done? The Yuchai diesel generator set manufacturers will give you a detailed introduction below.
Yuchai diesel generator sets are now the first choice for emergency power generation equipment, ensuring the normal power consumption of enterprises and us. The fire prevention of Yuchai generators is a key issue in use. The following editor will introduce the fire prevention measures of Yuchai generators.
(1) The normal range of parameters such as current, voltage, power, and temperature rise should be clearly specified in the field operation regulations to prevent the generator from overload and over-temperature operation.
(2) Install an automatic demagnetization device. The automatic demagnetization device has the effect of reducing generator failure and mitigating the consequences of the failure. When the generator dumps the load, the automatic demagnetization device can demagnetize as soon as possible, so that there is no danger of fire due to the large increase in the voltage of the generator.
(3) Prevent three-phase current asymmetry. The difference between the three-phase current of the turbo-generator should not exceed 10% of the rated current, and the difference of the three-phase current of the hydro-generator should generally not exceed 20% of the rated current.
(4) The generator should be installed with ammeters, voltmeters, wattmeters, temperature meters and other protective devices, and must be accurate and easy to use. Water-cooled generators shall be equipped with instruments for continuous monitoring of waterways and water quality. Hydrogen-cooled generators should be fitted with a hydrogen purity meter. During operation, the purity of hydrogen is above 96%, the oxygen content must not exceed 2%, and the humidity must not exceed 15 g / m3. When supplying fresh hydrogen to the generator, the purity should be above 99.5%, and the humidity should not exceed 5 g / m3. Hydrogen pipelines and valves should be clearly marked and numbered.
(5) Strengthen the inspection and maintenance of generators, and find out faults such as poor insulation, over-temperature, over-voltage, air leakage, and water leakage in time to ensure the safe operation of the generator.
(6) The air temperature of the air-cooled generator inlet should not exceed 40 ° C, the maximum should not exceed 50-55 ° C, and it should not be lower than 20 ° C to prevent frost and reduce the insulation strength.
The above are the fire prevention measures of Yuchai generator set. I hope it can be helpful to everyone.
