This article discusses the advantage and economic efficiency of the introduction of digital devices of operational blocking compared to traditional electromagnetic blocking. In modern conditions, the development of any company is associated with the introduction of digital technologies into the reproduction processes. A significant number of scientific papers have been published on this topic in recent years.
For domestic icebreakers LK-60 and LK-120, electric propulsion systems are described with a description of the structure of the power industry containing nuclear reactors and steam turbine installations. The characteristics of a high-power propulsive system of traditional design, respectively, with three and four shaft lines for movement in heavy ice conditions are given. Using the example of the high-power Azipod VRK manufactured by ABB (over 5 MW) for icebreakers and ice-class vessels, options for choosing propulsion systems and power supply systems are shown, which have a number of advantages over traditional electric propulsion systems, especially in terms of maneuverability and energy efficiency.
We are in a state where the information security industry of all economic entities and authorities of our country has faced enormous challenges. We are forced to resist foreign hacker groups and protect our digital economy from their attacks. I am convinced that in the end we will cope, and the domestic information security industry will come out of this confrontation much stronger and more stable. The article provides a forecast for the accelerated development of Russian information security solutions, and substantiates the assumption that the basis of this development will be the maximum use of artificial intelligence.
The article provides an analytical review of the state of the issue of controlled disconnectors, as well as the possibility of their reliable automation.
In this work, the influence of modes and parameters of milling with an end mill on the energy intensity of the cutting process is studied. An example of a methodology for calculating energy consumption, modes and milling parameters is presented. The results of the work will allow at the stage of technological preparation of production to select the most energy-intensive cutting modes for milling with an end mill.
The paper considers the issue of maintaining the power supply (uninterrupted power supply) of electric receivers and ensuring the necessary battery life of powerful installations for safe shutdown of production. A block diagram of uninterruptible power supplies (UPS of static type) based on ionistors with a description of its operation has been developed. The comparison of technical and economic indicators with other types of UPS is given.
The purpose of this work is the development of software and hardware, their further implementation into the system as a separate component of the whole system, and ultimately – the conduct of physical experiments on the accelerator on the cascade generator СG-2.5 with the registration of the main parameters in real time. Development of software in the language Turbo Pascal 7.1 and the introduction of IBM PC into the system makes it possible to transfer the system to a partial automatic mode of the accelerator, and then further improvement of the system will completely transfer it to full automatic mode.
The article considers the question of determining the degree of polymerization of paper-oil insulation of transformers using the optical method of research in the visible region of the spectrum. A method for determining the degree of polymerization of paper-oil insulation using a spectral device is presented.
