矿用电机车牵引电动机的现代发展阶段具有延缓其单位功率增大的特点。因此,主要对提高牵引电动机的质量予以注意。最现代化的电动机的故障次数占正在运转的电机车设备的故障总数的25～30％。但是,因为新机械设备的可靠性要根据试运转的效果来评定,所以在2—3年内制造具有所需可靠指标的机械设备是不可能的,这样,实际设计过程就会延长到5～6年。如果将设计、制造和使用视为同一过程,则在提高电动机可靠性的同时就可以缩短这一过程。 电机车的使用经验表明,在矿井的条件下,牵引电气设备会受到动负荷高能级的同时作用和环境(含瓦斯程度、含尘度)的不
The development stage of traction motor for mining electric locomotive has the characteristics of retarding the increase of unit power. Therefore, it is mainly necessary to pay attention to improving the quality of the traction motor. The most modern motor failures account for 25-30% of the total number of motor vehicle equipment failures in operation. However, since the reliability of new machinery depends on the effectiveness of commissioning, it is not possible to manufacture machinery with the required reliability in 2-3 years, so that the actual design process can be extended to 5-6 year. If you think of design, manufacture, and use as one and the same process, you can shorten the process while increasing motor reliability. The experience with the use of electric locomotives shows that under the conditions of the mine, the traction electrical equipment is not affected by the simultaneous action and environment (including the degree of gas and the dust content) of the dynamic load
