某机场地处沿海地区,夏季多风多雨,高温持续时间长,空气潮湿且酸碱盐成分含量较高,飞机地面存放环境比较恶劣,大多数装置安装在飞机上的边缘部位与非密封舱段的电气设备,受高温、高湿、霉雨、盐雾和沙尘等因素侵害十分严重,出现季节性故障多发现象。近两年来电气设备故障统计数据表明,夏季因气候影响所造成的电气机件故障占全年故障总数的40%~52%。对安全飞行造成较大的威胁,同时也提出了如何科学搞好电气设备夏季维护的重要课题。
An airport is located in the coastal areas, the summer windy and rainy, high temperature for a long time, the air is humid and acid-base salt content is high, the aircraft ground storage environment is harsh, most devices installed in the aircraft on the edge of the site and unsealed cabin Of the electrical equipment, subject to high temperature, high humidity, moldy rain, salt spray and dust and other factors is very serious, there are many seasonal failure phenomenon. The statistics of electrical equipment failures in the past two years show that the electrical machinery failures caused by the impact of the climate in summer accounts for 40% -52% of the total annual total number of faults. Which poses a great threat to safe flight. At the same time, it also put forward an important issue on how to do a scientific and scientific summer maintenance of electrical equipment.
