How to read electrical circuits, or Anatomy of symbols and special symbols

In our age of total electronics and electrification, various equipment that uses current in its work has become not only the affiliation of large enterprises and energy networks, but also home appliances. In this connection, the question of how to read electrical circuits is of interest to very many. Understanding the basic principles of circuit design, electrical processes in them, and standard graphic designations, you can easily read almost any drawing of this kind.

Before reading the electrical diagrams, it is necessary to get a good understanding of their structure and principles of construction. And then even the most complex and intricate scheme will no longer seem simply a meaningless set of "kabbalistic symbols" and ornate patterns. And the question of how to read the electrical circuits, will pass into the category of solved.

All graphic symbols have a rather simple form of outline. They, if possible, contain the most characteristic features and characteristics of each component, which greatly facilitates their memorization. Conventional designations do not reflect the dimensions of the element, but only its type and some technical characteristics. Having dealt with these wisdoms, you will take the first step to answering the question of how to learn how to read electrical circuits.

It is also necessary to know that all symbols necessarily contain certain alphanumeric abbreviations that display some parameters of these schema elements. A separate subject is a variety of lines that symbolize electrical wiring. The following types of lines are mainly used:

• Thick solid shows wires, cables, buses, windings, resistors, capacitors, etc .;
• A solid double thickened line denotes cores and connections to the body;
• Dashed thick - displays the grid of various electronic devices;
• Dashed thin - depicts lines of mechanical communication and screening on electrical circuits.

Knowing the meaning of the above notations can play a key role in answering the question of how to read the electrical circuits. However, the subtleties of conditional alphanumeric abbreviations are of no less importance, which by rules are written in the form of a certain sequence of letters, numbers and symbols in one line without spaces. The designation often consists of three parts: the type of the element, its number and the function to be performed.

The letter codes of element types are groups that are assigned specific values. They can be one- or two-letter. All their values are detailed in the technical documentation and in the special reference literature, where all the parameters of the elements that are represented in the diagrams by this symbol are very expanded. By the way, if you are interested in how to read the electrical diagrams of a car, you can be sure that for them this principle remains unchanged, since practically all documents of this kind are compiled according to a single standard.

True, not everything is so simple. There are many special schemes in which it is sometimes difficult to understand even professionals. There is little knowledge of conventional symbols. It is necessary to understand all the intricacies of this device. To understand and memorize symbols and alphanumeric abbreviations is not difficult, but they can give an idea only about the device device, but not about its principle of operation. To do this, we need at least a minimal theoretical basis.
