This paper analyzes the problem of occurrence and development of fatigue processes in the insulation of traction motors of autonomous locomotives. Factors causing destruction (cracking, delamination, occurrence of voids) of insulation in operation have been studied in the course of the research. Three characteristic stress cycles (reversible, repetitive, random) were described to make fatigue failure predictions. Outcomes of investigations of temperature conditions of windings of electric machines of diesel locomotives show that during operation the insulation experiences variable thermomechanical stresses. Received data can be recommended to take into account during the creation of new electric machines for diesel locomotives, as well as during the operation and resource recovery of already existing ones.

“…At the same time, China's social and economic development levels are getting higher and higher, and these are closely related to the rapid development of various industry sectors. In recent years, China's industrial production continued to develop, not only needing higher production conditions but also putting forward higher requirements for the production equipment, especially for the industrial production of the control system requires more [5]. The control system is directly related to the entire industrial production efficiency and quality and plays a vital role in the continuous development of industrial production.…”

As the scale of the electrical system becomes more and more large and the structure becomes more and more complex, the performance of the electrical automation device is therefore required to be higher. This paper studies the electrical system automation device, and from the perspective of universality, designs and establishes the hardware platform of the electrical system automation device composed of six plug-ins, such as human-machine interface, auxiliary switch input, AC input, communication, power supply, and central processor. On this basis, μC/OS-II is adopted as the embedded real-time operating system of this paper to develop and design the software of the electrical system automation device. Then, the principle of the protection device for embedded system electrical automation is analyzed, and a microcomputer line protection device based on the full-circle Fuchs algorithm is proposed. The empirical analysis of the embedded system electrical automation device shows that the maximum system task response time is 145 μs and the minimum is 10 μs, which are all no more than 1 ms. When testing including the single board state, the keyboard, the alphabetical mode, the basic function, and the single board line module sending and receiving, the pass rate of all the testing items is more than 99%, which verifies that this paper is based on the embedded real-time operating system of the feasibility and effectiveness of the electrical automation device.
