在环境气温高和空气湿度大的地方,会使柴油发电机组电机和电器的散热困难,导致内部温升增高,加速绝缘材料老化,同时,会使绝缘受潮、长霉,导致绝缘电阻降低,电气性能变坏,这些都使电机和电器的使用寿命降低。
In places with high ambient temperature and air humidity, it will make it difficult for the diesel generator set motor and electrical equipment to dissipate heat, resulting in increased internal temperature rise and accelerated aging of insulation materials. At the same time, it will damp and mold the insulation, resulting in reduced insulation resistance and deterioration of electrical performance, which will reduce the service life of the motor and electrical equipment.
此外,还对机组的其他部分并来一些不利的影响,如天然气发电机组的水温和油温过高,以及金属结构件锈蚀严重等。因此,使用在高温、高湿地方的机组,除了对金属结构件和油漆等按“湿热带型”(通常用产品特别环境带好TH表示)产品考虑,采取必要的防腐措施之外,还应特别注意通风散热,以及加强绝缘电阻的检查工作。
In addition, it also has some adverse effects on other parts of the unit, such as excessive water and oil temperatures of the natural gas generator unit, and serious corrosion of metal structural parts. Therefore, for units used in high temperature and high humidity areas, in addition to taking necessary anti-corrosion measures for metal structural parts and paint products according to the "hot and humid zone type" (usually expressed as th in the special environment of the product), special attention should also be paid to ventilation and heat dissipation, and the inspection of insulation resistance should be strengthened.
在低温环境中,尤其是当气温低于—20℃时,机组的燃油、润滑油变稠,粘度大,冷却水结冰,一般蓄电池的容量下降,导致起动和工作困难,同时电线和其他结构材料也变硬发脆,降低使用寿命。因此,在冬季工作时,需要采取必要的防冻和预热、保温措施。
In the low temperature environment, especially when the temperature is lower than - 20 ℃, the fuel oil and lubricating oil of the unit become thick, the viscosity is high, the cooling water is frozen, and the capacity of the general battery decreases, resulting in difficulties in starting and working. At the same time, wires and other structural materials become hard and brittle, reducing the service life. Therefore, when working in winter, it is necessary to take necessary anti freezing, preheating and thermal insulation measures.
