Ripper for processing slope fields

Abstract

The purpose of the study is to substantiate the parameters of a spherical disk working body. New technology of tillage of slope fields that prevent water erosion, a design scheme of a ripper for its implementation is presented. The ripper consists of lower and upper working bodies of the “paraglider” type and a spherical disk. The study applied the laws and rules of theoretical mechanics, agricultural mechanics, mathematical statistics, and methods of strain measurement and the methods given in the existing regulatory documents (TSt 63.04.2001, TSt 63.03.2001). The new technology of tillage of slope fields makes it possible to form step ridges on the surface of the arable land and on the bottom of the furrow, which protects the soil of the slopes from water erosion. It is established that when the diameter of the spherical disk of 510 mm, the curvature radius of 56 mm, tilt angle relative to the direction of motion of 28-30° to the vertical at an angle of 17-18°, the transverse and longitudinal distance between the disc and work on the bottom ripper respectively 30 and 20 cm ensures the formation of ridges on the surface of the field according to agrotechnical requirements at a minimum cost of energy.

Assessment of the quality of electricity by applying reactive power sources

“…where, U (n) -the current value of the N-harmonic component of the voltage, V; n -the order of the harmonic component of the voltage; N -The final order of the harmonic components of the voltage taken into account is determined by the standard. N = 40; 𝑈 -Rated voltage on the network, V. Economic advantages, based on the above in the facilities of the power grid complex, the advantages of a controlled transformer-type shunt reactor over a controlled magnetized shunt Reactor are undeniable and should be taken into account and used in the organization of competitions for the supply of this type of equipment for high-voltage networks [3]. The use of static thyristor compensators of reactive power in substations of high voltage power transmission lines allows you to stabilize the voltage, reduce losses in the transport of electricity and increase the transmission level and electrical conductivity by increasing its static stability.…”

Study of reliability indicators of cable lines in rural areas

“…The average recovery time of a cable line depends on the repair time, which in turn is determined by the status of the damaged line in the network scheme (the line is reserved or not reserved, the category of consumers) [7,8].…”
