Automatic control system of the current collector, equipped with intraspring pneumatic elements in carriages

Abstract

The article considers the methodology of static pressure level selection to ensure minimum wear of current collector elements. Static pressing is regulated by using controlled lifting pneumatic elements. However, their use can cause breakdowns of carriage springs and breakaways, which negatively affects the slipstream process. To optimize the operation, it is advisable to use controlled pneumatic elements in the carriages. The article also describes the concept and principles of the system operation for the automatic regulation of the current collector equipped with intraspring pneumatic elements in the carriage. The mathematical model of the current collector equipped with the system of automatic regulation of static pressure and static characteristic of the carriage has been developed. The conducted researches have shown prospectivity of applying the presented system of automatic regulation, allowing to achieve the increase in quality of current collector at the expense of decrease in quantity of tear-offs in a sliding contact.
