Review of the best programs for drawing electrical diagrams. Electrical engineering calculation programs Download a program for creating an electrical circuit

Algorithm for using the program. First, we must create equations for the circuit contours according to Kirchhoff's second law. You need to do this yourself using these articles:

After this we will get approximately the following equations ( for the method of loop currents, the algorithm will be the same as for the method of nodal and loop equations, only instead of I1 I2 I3 .... will be Ik1 Ik2 Ik3... )

40 = (23+1)*I2 + 14*I4+71*I1

20 = 55*I1 - (59+2)*I4 + 93*I2

0 = 60*I1 + 16*I2 – 81*I4

For convenience, we need to arrange the equations a little, that is, we add everything that can simply be added, and arrange the sequence of terms in the equations, so that in each of the equations the sequence of terms is the same.

E I1 I2 I4

40 = 71*I1 + 24*I2 + 14*I4

20 = 55*I1 + 93*I2 - 61*I4

0 = 60*I1 + 16*I2 - 81*I4

As you can see, we got four columns E, I1, I2, I4 Your column names may be different, for example E, I2, I3, I5 after this we accept the following equality:

E=E

The second third and fourth column are equal to IA, IB, IC.

E=E

Then our equations will look like:

40 = 71*IA + 24*IB + 14*IС

20 = 55*IA + 93*IB — 61*IС

0 = 60*IA + 16*IB — 81*IС

After this, we write the equation into the program.

Electrical schematic software is a tool used by engineers to create electronic circuits for the purpose of designing and testing products during the design, manufacturing, and operational stages. Accurate display of parameters is done using a scale. Each element has its own designation in the form of symbols corresponding to GOST.

Software for electrical circuits: why do I need it?

Using electrical diagramming software, you can create precise drawings and then save them to electronic form or print.

IMPORTANT! Almost all programs for drawing diagrams have ready-made elements in the library, so you don’t have to draw them manually.

Such programs can be paid or free. The former are characterized by great functionality, their capabilities are much wider. There are even whole automated systems CAD designs that are successfully used by engineers around the world. With the use of programs for drawing diagrams, the work is not only fully automated, but also extremely accurate.

Free programs are inferior in functionality to paid software, but with their help you can implement projects of initial and medium complexity.

The software allows you to simplify your work and make it more efficient. We have prepared a list of popular programs for creating circuits used by specialists around the world. But first, let's figure out what schemes are and what types they come in.

Programs: what schemes are they intended for?

The diagram is a graphic type design document. It displays the components of the device and the connections between them in the form of symbols.

The diagrams are part of the design documentation set. They contain the data necessary for the design, production, assembly, regulation, and use of the device.

When are diagrams needed?

1. Design process. They allow you to determine the structure of the product being developed.
2. Production process. They provide an opportunity to demonstrate the design. Based on them, it is being developed process, method of installation and control.
3. Operation process. Using the diagrams, you can determine the cause of the breakdown, correct repair and maintenance.

Types of schemes according to GOST:

• kinematic;
• gas;
• energy;
• pneumatic;
• hydraulic;
• electrical;
• combined;
• optical;
• divisions;
• vacuum

Which program is better to work in?

There are a huge number of paid and free development programs electrical drawings. The functionality is the same for all, with the exception of advanced features for paid ones.

Today, not a single experienced electrician uses manual drawing of electrical circuits on a piece of paper. It is much easier, more convenient and clearer to draw up a project for the electrical wiring of a room on a computer using a special software package in Russian. However, the problem is that not all programs are easy to use, so when you stumble upon an inconvenient and, moreover, paid version software, most old-school masters simply discard modern way modeling aside. Next, we will provide readers of the site with an overview of the simplest programs for drawing electrical diagrams of apartments and houses on a computer.

Free software

There are not many Russian-language, easy-to-use, and also free software for creating single-line electrical diagrams on a computer. So, we have created a small rating so that you know which programs are best for drawing power supply diagrams for houses and apartments:

1. . Oddly enough, the most popular and, no less important, free program for drawing single-line electrical diagrams on a computer is the vector graphics editor Visio. With its help, even a novice electrician can quickly draw a circuit diagram of a house or apartment. As for the functionality, they are not as advanced as the software that we will provide below. To summarize, we can say that Microsoft Visio is easy to use and at the same time in Russian free program for modeling electrical circuits, which is suitable for home electricians.
2. . A more professional software package for designing indoor electrical circuits. Compass has its own database, which stores the names and ratings of all the most popular types of automation, relay protection, low-voltage installations and other circuit elements. In addition, the database contains graphic symbols of all these elements, which will make it possible to create a clear diagram of the power supply or even a separate switchboard. The software is completely in Russian and you can download it for free.
   
3. Eagle(Easily Applicable Graphical Layout Editor). This software package will allow you not only to draw single-line power supply diagrams, but also to independently develop a drawing of a printed circuit board. As for the latter, drawing can be done either manually or without your own participation (in automatic mode). Today there are both paid and free versions of the Eagle program. For home use It will be enough to download the version labeled “Freeware” (there are some restrictions in relation to maximum size useful area of ​​the printed circuit board). The disadvantage of this software package is that it is not officially Russified, although if you try a little, you can find a Russifier on the Internet, which will allow you to draw electrical diagrams of apartments and houses without any obstacles.
   
4. Dip Trace. Another popular program for drawing electrical circuits and creating routes for printed circuit boards. The program is simple and easy to use, and is also entirely in Russian. The interface allows you to design printed circuit board in volumetric form, using a database with ready-made elements electrical circuit. You can evaluate the full functionality of the software only for money, but there is also a stripped-down free version, which will be quite enough for a novice electrician.
   
5. " A completely free program for drawing electrical circuits on a computer. From the official website you can download it in Russian and full version. In addition to modeling power supply projects for apartments, houses and other types of premises, in this software package you can easily create a diagram in which the most suitable ratings of circuit breakers, relay protection, etc. will immediately be provided. A nice addition to this software is a database with stickers that can be printed and pasted in your own distribution panel to graphically designate all circuit elements according to GOST.
   
6. . One of the free versions of the popular AutoCAD editor is AutoCAD Electrician. Briefly about this software, we can say the following: the functionality is suitable for both beginners and professional electricians working in the energy field. Everything in the interface is simple, you can quickly figure it out. All functions are in Russian, so you can easily use AutoCAD to draw electrical wiring diagrams for your house or apartment.
   
7. Elf. An interesting name for a simple program for modeling power supply circuits in construction drawing. The software package itself is no less interesting and multifunctional. Using the Elf Design program, you can create power supply drawings of any complexity. In addition, the software helps with the appropriate denomination, etc. "Elf Design" is a completely free software package in Russian.

KOMPAS-Electric

In addition to the 7 programs provided for drawing electrical circuits, there are more than a dozen editors in which you can draw up a basic plan for the power supply of a house or apartment for free, but other programs have a more complex interface or problems with the Russian version. We recommend giving preference to representatives of this rating, so as not to waste time in the future searching for localization codes, user manuals, and the like!

Paid software

We reviewed free programs for creating electrical circuits on our own. However, you yourself understand that the paid versions provide a wider range of features and convenient add-ons that will allow you to draw an electrical circuit on your computer. There are many popular paid programs for drawing electrical circuits. We have provided some of them above, but there is one more program that is worth talking about a little - sPlan. This is one of the easiest to use and also multifunctional software packages for drawing up electrical wiring diagrams and tracing electronic boards. The interface is convenient, in Russian. The database contains all the most popular graphic elements for drawing electrical circuits.
