Designation of the socket in the electrical circuit. Designation of the outlet on the scheme: GOST

Due to its specificity in the technical industry there are many schemes and drawings. A competent engineer should not only read these schemes confidently, but also be able to make them. Since there are a lot of directions in engineering, each structure has its own nuances, it was decided to standardize the principles of drawing drawings and schemes.

For simplified drawing up and reading of drawings the state standard generalized all elements and devices in the document under number GOST 21.614 and GOST 21.608. It also describes the rules for drawing conditionally graphic images in the drawing, including the designation of the socket on the diagram.

Causes of HBV

The abbreviation OUG is deciphered as a designation conditionally graphic. Due to the fact that the drawing is an official document, then it must be drafted correctly. If everything is done as it should, then this will accurately interpret the contents of the drawing. If such rules did not exist, there would be many controversial issues in the manufacture of a part or the construction of a structure.

At a time when the drawings were drawn by hand, engineers tried in every possible way to simplify the drawing process. This allowed for a short time to produce design and survey documentation. In modern construction for a long time using special software for the implementation of drawings. They greatly simplify the lives of designers, but the IBMs are still relevant. In electrical engineering, all 95% of the drawings consist of only one conventional image.

There are a lot of elements in the drawing, especially for building drawings. The scale of the sketching of the premises is from one hundred to five hundred. This means that the area of the premises can be reduced by a hundred or five hundred times.

At one-hundredth of a scale, one centimeter on a sheet of paper is equivalent to one meter in reality. Sometimes designers need to fit on a small sheet of paper a lot of elements. To solve this problem, IUG is used. This allows for a flat format to arrange multi-level electrical elements.

Designation of the outlet on the scheme

When building a house or a production building, you can not do without installing electrical appliances or appliances. In order to understand where to place this or that device, the builder draws attention to the designation of the socket on the electrical circuit.

The design of the section "Electrical equipment" assumes the drawing up of all necessary drawings. The basic set of drawings for the construction of a certain floor or room includes several types of documentation. The first is a single-line diagram of the switchgear - it displays all the consumers depicted by conventional signs, the next is the plan for their placement in the room. Next comes the specification.

In civil engineering, a significant part of the conditionally graphic elements are electrical outlets. The socket allows to deliver electric energy from the power plant or substation to the end user.

Everyone knows that the socket is located on the wall. In the modern world, almost all devices operate on electric power from a 220-volt network. Consequently, in apartments or offices their number is rarely less than two.

Types of designation of sockets on the plans

As well as electrical equipment, the sockets can be of different kinds and purposes. Consequently, the designation of the socket on the circuit is required in various ways. Let's consider the main types of sockets:

• Two-pole - these are ordinary sockets 220 volts, which are installed in the apartments;
• Three-pole - the same bipolar sockets, but with an additionally grounded conductor, they are a modern European standard;
• Four-pole - the old standard, used at a voltage level of 380 volts; Such sockets are mainly found in industry (if necessary in connection of a three-phase motor of low power);
• 5-pole are used for special connections of industrial equipment.

Kinds of sockets by a way of installation

In addition to the specific design, the sockets are distinguished by the installation method:

• With concealed installation (integrable into the wall);
• With an open installation (they have their own body, which is fixed to the bearing surface);
• With outdoor installation (have a protective housing with high dust and water resistance, designed for outdoor installation).

In the European system of marking of electrical equipment, depending on the degree of protection from penetration of dust and moisture, two Latin letters IP and a two-digit number are used. The first figure means protection from penetration of third-party items, the second - from penetration of moisture. There are values from 0 to 9, the larger the digit, the better the protection.

Designation of sockets in the GOST scheme

In the norms, the designation of the socket on the circuit is clearly indicated. The socket is generally represented in the form of a semicircle with a line extending up from the circle. The dash indicates the type of outlet. One means that the socket is bipolar, two parallel features - respectively, a bipolar double.

Three features, located fan, mean that the socket is three-pole. If there is a contact with the protective conductor connected, a flat line parallel to the center of the semicircle is drawn, this is true for all outlets of an open installation.

The designation of sockets, circuit breakers on the schemes with the concealed installation is as follows: in the center of the semicircle one more feature is drawn. It is directed from the center to the dash, which indicates the number of poles of the socket. Often, such a socket just walled into the wall. It has a low degree of protection, but due to the fact that all open conductive parts are hidden in the wall, it is completely safe.

There is also a designation of sockets, switches on circuits with a painted semi-circle in black. This means that we have a socket with an increased IP value. This allows you to install it outdoors, for example on the street.
