Summary of the symbols used in electroschemes

Graphic

As for the graphic symbols of all the elements used in the scheme, this review we will provide in tabular form in which the product will be groupedfor other purposes.

In the first table, you can see how the marked electrical boxes, panels, cabinets and panels in wiring diagram:

The next thing you need to know - the symbol supply sockets and switches (including a walk-through) on the single-line diagram of apartmentsand private homes:

With regard to lighting elements, lighting fixtures and lamps according to GOST indicate as follows:

In more complex schemes, which apply electric motors, may indicate items such as:

also useful to know how to graphically indicated by transformers and chokes on the wiring diagram:

Electrical appliances GOST have the following graphic symbol in the drawings:

and here, by the way, useful for beginners electricians table thatshows what it looks like in the plan wiring grounding circuit, as well as the very power line:

Besides the diagrams you can see the wavy or straight line, "+" and "-" to indicate the kind of current, voltage and shapepulse:

In more complex automation schemes you can meet strange graphic symbols, such contact connections.Remember how these devices are indicated in wiring diagram:

addition, you should be aware of the look of radioactive elements in the projects (diodes, resistors, transistors, etc.):

Hereall conditional graphic designations in electrical circuits and power circuits of lighting.As already convinced themselves that make up quite a bit and remember how each can be designated only with experience.Therefore we recommend to save all of these tables that when reading the project home wiring plan or apartment you can immediately determine what kind of circuit element is in a particular place.

Letter

We have already told you how to decipher the coded wires and cables.In single-line electroschemes also present their letters make it clear what is included in the network.Thus, according to GOST 7624-55, lettering elements on electric circuits as follows:

1. relay current, voltage, power, resistance, time, intermediate, pointing, gas and exposure time, respectively - RT, RN, RM, PC, RV, RP, RU, RG, RTV.
2. CG - control button.
3. HF - limit switch.
4. QC - Teams controller.
5. PV - limit switch.
6. DW - the main engine.
7. to - the engine cooling pump.
8. DBH - the engine of rapid moves.
9. DP - engine innings.
10. LH - spindle motor.

In addition, the labeling of domestic radio components and electric circuits are the following letter designations:

In this brief overview of the symbols in electrical circuits is completed.Hopefully, now you know how to designated outlets, switches, light fixtures and other elements of the circuit in the drawings and plans of the premises.
