Comments on the article

7.1.1. This chapter of the Rules applies to electrical installations: residential buildings listed in SNiP 2.08.01-89 "Residential buildings"; public buildings listed in SNiP 2.08.02-89 "Public buildings and structures" (with the exception of buildings and premises listed in Chapter 7.2): administrative and amenity buildings listed in SNiP 2.09.04-87 "Administrative and amenity buildings" ; electrical installations of unique and other special buildings that are not included in the above list may be subject to additional requirements.

Hereinafter, unless otherwise specified, the word "buildings" refers to all types of buildings covered by this chapter.

The requirements of this chapter do not apply to special electrical installations in medical institutions, organizations and institutions of science and scientific service, to dispatching and communication systems, as well as to electrical installations that, by their nature, should be classified as electrical installations of industrial enterprises (workshops, boiler rooms, thermal points, pumping stations, laundry factories, dry cleaning factories, etc.).

7.1.2. Electrical installations of buildings, in addition to the requirements of this chapter, must meet the requirements of the chapters of Sec. 1-6 of the PUE to the extent that they are not changed by this chapter.

7.1.3. Input device (VU) - a set of structures, devices and devices installed at the input of the supply line to the building or to its separate part.

The input device, which also includes devices and devices of outgoing lines, is called an input-distribution device (ASU).

7.1.4. The main switchboard (MSB) is a switchboard through which the entire building or its separate part is supplied with electricity. The role of the main switchboard can be performed by an ASU or a low-voltage shield of a substation.

7.1.5. Distribution point (RP) - a device in which protection devices and switching devices (or only protection devices) are installed for individual electrical receivers or their groups (electric motors, group shields).

7.1.6. Group shield - a device in which protection devices and switching devices (or only protection devices) are installed for individual groups of lamps, plug sockets and stationary electrical receivers.

7.1.7. Apartment shield - a group shield installed in an apartment and designed to connect a network that feeds lamps, sockets and stationary electrical receivers of an apartment.

7.1.8. Floor switchboard - a switchboard installed on the floors of residential buildings and designed to power apartments or apartment switchboards.

7.1.9. Electrical room - room. accessible only to service qualified personnel, in which VU, ASU, MSB and other switchgears are installed.

7.1.10. Supply network - a network from a switchgear of a substation or a branch from overhead power lines to VU, ASU, MSB.

7.1.11. Distribution network - a network from VU, ASU, MSB to distribution points and shields.

7.1.12. Group network - a network from shields and distribution points to lamps, sockets and other electrical receivers.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

solar ball 10.07.2011

So called Jonathan Liou, a student from Australia, he invented a simple and inexpensive device for water purification and desalination.

Dirty water, poured into a transparent plastic ball exposed to the sun, gradually evaporates. Pure water condenses on the upper hemisphere and flows from there into the annular pan at the "equator" of the ball. During the day, you can collect three liters of water suitable for drinking.
