A cooker hood is an integral element of a kitchen interior. A range hood provides a comfortable stay for people in the room, clearing the air of unwanted odors and burning. If you need to connect a cooker hood, a lot of questions arise, one of which is how to connect a cooker hood to an electrical network.

The connection of the hood is carried out, as a rule, in a conventional power outlet. Therefore, it is recommended to provide a socket for connecting the hood when performing work on replacing the electrical wiring of the apartment. Consider the features of installing a socket for a kitchen hood.

The power consumption of the cooker hood is relatively small, so it is not practical to pull a separate wiring line from the distribution panel. The outlet in this case can be connected in a junction box. If during the installation of wiring in the kitchen ...

Before talking about the choice of a differential automaton, it should be explained how this issue has earned such popularity. Why are differential automata good? Of course, by the fact that the difavtomat is a device that provides the line not only protection against overload currents and overcurrents of short circuit, but also protection against leakage currents, that is, protection against electric shock from a person.

In other words, a single device provides the full range of necessary protections. This is very convenient because it saves space in the distribution board and simplifies installation. In some cases, money savings are also achieved, but this is relative, since a high-quality differential machine can be more expensive than a single ordinary machine and a residual current device (RCD). So, what is good for difavtomat, clearly. It remains to decide how to choose it ...

"Rules for the installation of electrical installations" allow only 3 ways to connect conductors: soldering, welding and clamping in terminals. This also applies to pre-twisted wires in junction boxes. The best electrical characteristics, reliability and durability are uniquely welding. In addition, with a large number of compounds, this method is also the fastest and cheapest. With copper wires, the issue is resolved and closed.

However, despite the requirements of the 7th edition of the PUE on the termination of the use of aluminum wires for electrical wiring (with a cross section of less than 16 sq. Mm.), They are still used and quite widely. For example, during the repair (without complete replacement) of the old aluminum wiring. Combining copper with aluminum is even worse than leaving aluminum. Thus, the question of welding aluminum becomes very relevant, especially since its physical and chemical properties other connection methods make it difficult...

This article is intended for those who want to connect the gas generator to the ABP unit without assistance. But, before you start connecting the generator to the automation, you need to know a little about the device and the principle of operation of the generator.

There is no sense in thoroughly understanding the device and the principle of operation of mini-power plants, this information on the Internet is more than enough, we just need to understand how the generator works, where you need to connect the control wires from the autostart system. That is, only practical information, without unnecessary theory and "water."

This method of connecting the generator is suitable for most single-cylinder generators up to 5-6 kW equipped with an electric starter. So, for starters, consider how a gas generator starts up. Close the air damper before starting the engine., turn the ignition key to the "START" position. After the generator engine wound up ...

Somewhat better results are obtained using circuits using two thyristors connected in opposite directions - in parallel: there is no need for extra diodes, and thyristors are easier to operate. Such a circuit is shown in the figure.

The control pulses for each thyristor are generated separately by the circuit on the dynistors V3, V4 and capacitors C1, C2. The power in the load is regulated by a variable resistor R5.

But two thyristors are also impermissible luxury. Therefore, the electronic industry has mastered the production of triacs, or, as they are otherwise called symmetrical thyristors. With the dimensions and shape of the case, the triac is similar to a conventional thyristor, only two thyristors “live” inside it, connected in the same way as thyristors V1 and V2 are connected in the figure. In this case, the triac has only one control electrode ...

The specifics of installing electrical wiring in a wooden house is that wood is a combustible material. Therefore, any malfunction associated with a short circuit, overloading of cable lines and their overheating can lead to fire and fire.

Therefore, the features of installing electrical wiring in a wooden house are: hidden wiring - either in metal pipes, or according to the outline of the plaster. Open wiring - strictly either in a corrugated pipe, or in boxes, or on rollers.

In addition, the installation of switches and sockets on wooden walls is possible only when using insulating linings made of material that does not spread combustion. Often such linings come with electrical products. Well, of course, in a wooden house, protective grounding is of particular importance ...

An electric convector is one of the most popular heaters used for heating domestic, industrial and office premises. Despite the rather wide popularity of this type of heater, few people have an idea of ​​how it works, and for what these or other control elements of the convector serve.

Consider the principle of operation of a convection heater. The principle of operation of an electric convector is based on the natural circulation (convection) of air. The convector, as a rule, has a rectangular shape, an electric heating element is located inside it.

On the surface of the convector there are openings designed for air circulation. The convector is designed in such a way that the air coming from the lower and side openings is heated after passing through the heating element and then exits through the openings ...

Thyristor power controllers are one of the most common amateur radio designs, and this is not surprising. After all, everyone who has ever used an ordinary 25 - 40 watt soldering iron, its ability to overheat is even very well known. The soldering iron begins to smoke and hiss, then, soon enough, the tinned sting burns out, turns black. Soldering with such a soldering iron is already completely impossible.

And here the power regulator comes to the rescue, with the help of which you can set the temperature for soldering quite accurately. It should be guided by the fact that when a soldering iron touches a piece of rosin, it smokes well, so, medium, without hissing and splashing, not very energetically. You should focus on the fact that the soldering is contour, shiny. Of course, modern soldering stations are equipped with soldering irons with thermal stabilization, digital indication and adjustment of the heating temperature ...

Sauna is, first of all, a bath. And the creation and maintenance of the necessary microclimate in the bathhouse is a very technologically challenging task. Therefore, it is clear that the bath furnace plays a major role in this process.

And it is not surprising that today sauna furnaces have long been automated and electrified. The microclimate in the sauna is at the mercy of a technique that never makes mistakes and never forgets anything. A modern sauna stove is, in the vast majority of cases, a factory electrical appliance that incorporates several structural elements and requires competent connection and installation.

The structural elements of an electric sauna stove are as follows: The stove itself with a heater and built-in heating elements, as well as terminals for connection. Optionally, the furnace can include a steam generator as well as a tank designed for automatic or manual filling with water ...

A circuit breaker, or, more simply, an automaton, is an electrical device familiar to almost everyone. Everyone knows that the machine disconnects the network when there are any problems in it. If not smart, then these problems are too much electric current. Excessive electric current is dangerous for all conductors and household electrical equipment to fail, possibly overheating, igniting, and, accordingly, a fire. Therefore, protection against high currents is a classic of electrical circuits, and it existed even at the dawn of electrification.

Any overcurrent protection device has two important tasks: to recognize an unnecessarily high current on time and correctly, to break the circuit before this current can cause any damage. At the same time, high currents can be divided into two categories: large currents caused by network congestion, for example ...

Without energy, human life is unthinkable. We are all used to using fossil fuels as energy sources - coal, gas, oil. However, their reserves in nature are known to be limited. And sooner or later the day will come when they will run out. To the question "what to do in anticipation of the energy crisis?" the answer has long been found: we must look for other sources of energy - alternative, non-traditional, renewable. What are currently the main alternative sources of energy?

Solar energy. All kinds of solar systems use solar radiation as an alternative source of energy. Radiation from the Sun can be used both for the needs of heat supply and for generating electricity (using photovoltaic cells). The advantages of solar energy include the renewability of this energy source ...

Of course, there are so many ways to connect wires. All kinds of terminal blocks are widely known: screw and spring, insulated and not. Nut clamps and piercing clamps are popular. Finally, some people simply do not pay attention to common norms, preferring elementary twists. And one of the most reliable connections is wire crimping.

After crimping, the wire strands cannot be disconnected without cutting them, i.e. this is an integral connection. But it does not need maintenance either. The essence of crimping is reduced to the joint deformation of the connecting cores and the crimping sleeve into which these cores are inserted. The sleeve is compressed, deformed, compresses the cores, microroughnesses on the surface of the metal conductors are in mutual engagement, and reliable electrical contact is ensured. But it only seems that everything is so simple ...
