This article is about using robots in the energy field. We will consider several modern solutions that not only make it easier for a person to work and free his time, but also serve as cost-saving services for servicing industrial energy facilities. Today we can already confidently say that such tasks as: diagnostics of power lines, their cleaning from ice, inspection of wind turbines, maintenance of solar panels, diagnostics and maintenance of nuclear reactors - in the near future it will be possible to solve exactly mobile fully autonomous robots , or robots with remote control.

The use of robots is especially appropriate where human life may be at risk. For example, for the diagnosis of failed nuclear reactors or for the prevention of high voltage power lines located at a height of tens of meters above the ground ...

Among the protective devices in home wiring, residual current circuit breakers (RCDs) and differential machines (difavtomats) are becoming increasingly popular. Manufacturers produce them with various types of designs for use in single-phase and three-phase power supply schemes. All these devices have a common algorithm of work.

By and large, the difference between the RCD from the differential automaton is the absence in the circuit of a circuit breaker that responds to excess load currents. Therefore, the connection diagram of a single-phase or three-phase RCD from the connection diagram of a differential automaton differs only in the absence of this function. To protect against short circuits and unacceptable loads, additional current protection is required in it. A common element of these defenses is the scheme ...

Automation is increasingly being introduced into the everyday life of modern people. And if earlier, automated production could be considered the peak of progress, now even life, an apartment or a private house can be quite dramatically improved by bringing the concept of “smart home” there. Indeed, today the “smart home” systems are designed not only to optimize energy costs, but first of all - to make a person’s life more comfortable. The capabilities of modern smart home systems will be discussed in our article.

Combining home cinema, lighting control, water supply, video surveillance system, climate control, fire alarm, power supply and access control, gas supply and multi-room into one system is the task that the smart home system solves today. Let's go through each of the items sequentially, consider what they can ...

To adjust the brightness of the glow of the lamps, special electronic devices are used - dimmers. And if earlier this concerned only incandescent lamps, then with the advent of LED lamps on the market, there was a need to regulate them. In general, the dimmer function is to lower the average current through the lamp to the desired level, and thus reduce the intensity of the light emitted by it.

So, with incandescent lamps, triac and thyristor dimmers are traditionally used, which adjust the power supply to the lamp by cutting off part of the phase of the mains voltage. Since incandescent lamps are quite ingenious devices, then dimmers for them are quite simple in design. With LED lamps, the situation is more complicated.

Ordinary LED lamps sometimes contain in their design, in addition to LEDs, also a simple pulse converter circuit, which is designed to interact with an ordinary ...

Cables and wires are designed to transmit electrical energy over distances with the least possible loss. In order to transfer power from the source to consumers most efficiently, they are created with the maximum conductivity of the conductive lines and the exception of the formation of random, unauthorized paths of energy drainage by leakage currents. Only the simultaneous fulfillment of these conditions makes it possible to reliably and continuously transmit and receive electrical energy.

Power losses that occur during the passage of currents through metals are directly related to the magnitude of their electrical resistance. They increase with its increase. To improve the passage of electric current through wires and cables, they reduce the resistance of their conductors by selecting the material of conductive conductors by the value of the resistivity of metals and alloys, manufacturing a cross section of the core according to the permissible ...

Light-emitting semiconductor devices are widely used for lighting systems and as indicators of electric current. They relate to electronic devices operating under the applied voltage. Since its value is insignificant, such sources belong to low-voltage devices, they have an increased degree of safety regarding the effect of electric current on the human body. The risks of injuries increase when sources of increased voltage, for example, a household home network, which require the inclusion of special power supplies in the circuit, are used to illuminate them.

A distinctive feature of the design of the LED is a higher mechanical strength of the housing than that of Illich and fluorescent lamps. With proper operation, they work long and reliably. Their resource is 100 times higher than that of incandescent filaments, reaching one hundred thousand hours ...

As soon as the production of LEDs reached industrially significant proportions, their widespread introduction began. The use of LEDs these days is so vast that if you look around you will almost certainly catch something that has LEDs. What explains their popularity?

It's simple: the LED is a very efficient, safe, and inexpensive light source that meets many lighting needs, not inferior to either incandescent or neon lamps, and in fact, significantly surpassing them all. Where are the LEDs used, what are their areas of application? We will try to give an answer to this question here. First of all, pay attention to the fact that many LCD screens, for example, TV screens, monitors, displays of mobile phones, and various mobile gadgetshave LED backlight. This applies to both old models and the latest ...

Indoor artificial lighting is divided into general, the fixtures of which are usually located on the ceiling, local with wall sources used to create improved working conditions or to solve specific design goals.

According to the principle of using switches, wall lamps have designs when the switch is located on the power cord of the lamp with a plug that is inserted into a socket, mounted in the wall and connected by wiring hidden in a strob inside the wall, installed inside the lamp housing, remotely controlled, for example, using a cord or over the air using the remote control.

Recently, spotlights and spots that create directional light have become widely used. According to the control method, they can use one of the above inclusion options ...
