【摘要】：青藏高原地域辽阔,水力资源丰富,但大部分地区海拔高、气候寒冷、自然条件恶劣,对水电工程建设十分不利,对电站机电设备的影响尤为严重。根据西部水力资源的开发需要,为了保障电站机电设备的运行安全,以西藏藏木电站卷扬式闸门启闭设备为例,从设备的关键部件入手,详细分析了电机、润滑油、钢材、化工产品、电气装置等受低温、低气压、强紫外线照射的不利影响,如电机额定功率的损失和绝缘失效、润滑油的冻结和设备效率降低、钢材的冲击韧性降低、化工产品加速老化变脆等。针对这些不利影响,提出了加热、保温、修正电机功率、选用高原型电气设备、选择低温下冲击韧性满足需求的结构件用钢等对策及措施。
[Abstract]:The Qinghai-Xizang Plateau is vast in territory and rich in hydraulic resources, but in most areas, the altitude is high, the climate is cold, and the natural conditions are bad, which is very disadvantageous to the construction of hydropower projects, especially to the electromechanical equipment of power stations. In order to ensure the operation safety of the electromechanical equipment of the power station, according to the needs of the development of the hydraulic resources in the west, taking the hoisting gate hoist of Tibet Tibet Tibet Tibetan Wood Power Station as an example, starting with the key components of the equipment, the motor, lubricating oil and steel are analyzed in detail. Chemical products, electrical devices and so on are adversely affected by low temperature, low pressure and strong ultraviolet radiation, such as loss of rated power and failure of insulation of motor, freezing of lubricating oil, reduction of equipment efficiency, reduction of impact toughness of steel, Chemical products accelerated aging brittle and so on. In view of these adverse effects, the countermeasures and measures are put forward, such as heating, heat preservation, modification of motor power, selection of plateau type electrical equipment and selection of structural steel with low temperature impact toughness to meet the demand.
