随着我国铁路电气化事业的进一步发展,电力机车将在我国铁路干线上承担越来越多的客、货运输任务。由于我国幅员辽阔,各条铁路干线的运行条件随着各地气候的不同有着很大的差略。在高温、多雨地区,牵引电动机工作条件大大恶化。为保证牵引电动机能在这些地区正常工作,根据1982年铁道部在杭洲召开的牵引电机、电器部颁标准审查会议上提出的《机车用直流电机基本技术条件报审稿》的规定,牵引电动机型式试验应做湿热试验。其目的是;考核
With the further development of China’s railway electrification, electric locomotives will undertake more and more passenger and cargo transportation tasks on the railway lines in our country. Owing to the vast territory of our country, the operating conditions of various railway lines vary greatly with the climate of different places. In high temperature, rainy areas, traction motor conditions greatly deteriorated. In order to ensure that the traction motor can work normally in these areas, according to the provisions of “Review of Basic Technical Conditions of DC Motor for Locomotive” put forward by the Ministry of Railways in the review meeting of the traction motor and electric appliance department held in Hang Zhou in 1982, the traction motor Type test should be done damp heat test. Its purpose is; assessment
