INFLUENCE OF CURRENT FREQUENCY ON TECHNOLOGICAL AND ENERGY CHARACTERISTICS OF OF SCRAPER INSTALLATIONS FOR CLEANING MANURE
Journal Title: Енергетика і автоматика - Year 2018, Vol 0, Issue 5
Abstract
The purpose of the study was to determine the influence of the frequency of the current on the technological and energy characteristics of scraper installations for cleaning manure. The speed and performance of the scraper installation directly proportional to the frequency of the current. Changing the frequency of the current affects the loss of power in the electric motor. Reducing the current frequency causes an increase in the specific power consumption in scraper units, and its increase - decrease. In frequency-controlled electric drives, when the current frequency decreases, compared with the nominal specific power consumption, it decreases by 2 – 3 % compared with unregulated electric drive, and increases with increasing frequency. On the basis of the conducted research it was established that when the current frequency is reduced by 40 %, the efficiency of the scraper units decreases to 4 0%, and the specific power consumption increases by 61 %.
