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 leaves 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 the usual 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 thermally stabilized soldering irons, digital indicators and adjustable heating temperatures ...

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, 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 energy sources?

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 ...
