5.2.2. Generators, synchronous compensators and their auxiliaries installed outdoors must be specially designed.

5.2.3. The design of generators and synchronous compensators should ensure their normal operation and for 20-25 years with the possibility of replacing wear and damage parts and assemblies using the main lifting mechanisms and small-scale mechanization without complete disassembly of the machine.

The design of the hydrogenerator and its water supply system should provide for the possibility of complete removal of water and the absence of stagnant zones during repairs at any time of the year.

5.2.4. Generators and synchronous compensators must be equipped with instrumentation in accordance with Ch. 1.6, control, signaling, protection devices in accordance with 3.2.34 - 3.2.50 and 3.2.72 - 3.2.90, AGP devices for protecting the rotor from overvoltage, ARV in accordance with 3.3.52 - 3.3.60, as well as devices automation to ensure automatic start-up, operation and shutdown of the unit. In addition, turbine generators of 100 MW or more and hydrogen-cooled synchronous expansion joints must be equipped with bearing vibration remote monitoring devices. Turbo and hydro generators with a capacity of 300 MW and more must also be equipped with oscilloscopes with a record of the pre-emergency process.

5.2.5. Control panels, relay protection, automation, excitation and direct water cooling of the hydrogenerator should, as a rule, be located in close proximity to it.

5.2.6. The electrical and mechanical parameters of powerful turbo and hydro generators should, as a rule, be taken as optimal in terms of load capacity. If it is necessary to ensure the stability of operation, the parameters of the generators can be taken different from the optimal ones in terms of load capacity when justified by technical and economic calculations.

5.2.7. Generator voltage should be taken on the basis of technical and economic calculations in agreement with the manufacturer and in accordance with the requirements of the current GOST.

5.2.8. The installation of additional equipment for the use of hydro generators as synchronous compensators must be justified by technical and economic calculations.

5.2.9. For installation, disassembly and assembly of generators, synchronous compensators and their auxiliary equipment, stationary, mobile or inventory lifting and transport devices and mechanisms must be provided.

5.2.10. When using external cranes for hydroelectric power plants, simple measures should be taken to prevent the effects of rain and snow on equipment during prolonged opening of premises and installation sites.

5.2.11. Power plants must have facilities for storing reserve stator winding rods. The premises must be dry, heated, with a temperature not lower than plus 5ºС, equipped with special racks.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Serotonin helps burn fat 02.02.2017

Serotonin - the so-called happiness hormone - helps burn fat. This was reported by Researchers from the Scripps Institute (USA).

The researchers conducted the experiment with the roundworm Caenorhabditis elegans, which is often used as a model organism in biology. These worms have simpler metabolic systems than humans, but their brains produce virtually the same signaling molecules as humans.

Scientists were trying to find a gene that is directly related to serotonin and fat metabolism. As a result, a gene was discovered that programs the neuropeptide FLP-7. Experts have suggested that the neuropeptide has an effect on the level of the hormone of happiness in the brain. To confirm their theory, they tagged FLP-7 with a fluorescent protein and then tracked its movement through the body of the worm.

It turned out that FLP-7 is formed at a high level of serotonin. Then it passes into the intestines, where the process of fat burning begins. At the same time, biologists have noticed that if serotonin is added to the body artificially, this will lead to serious malfunctions.
