How to read electrical diagrams or the Anatomy of symbols and special characters

In this age of total electronics and electrification of various equipment using the electrical power has become not only a part of large enterprises and networks, but also home appliances. In this regard, the question of how to read electrical schematics, many people are interested in. Understanding the basic principles of circuits, the electrical processes occurring in them, and standard graphic symbols, you will be able to easily read virtually any drawing of this kind.

Before you start to read electrical diagrams, you need to understand their structure and principles of construction. And then even the most complex and convoluted scheme will not be just a meaningless series of “cabalistic symbols” and ornate patterns. And the question about how to read the wiring diagrams, go into the category of resolved.

All graphic symbols characteristic of a rather simple form of the faces. They, if possible, contain the most characteristic features and features of each component, which greatly facilitates their memorization. Symbols do not affect the size of the element, only its type and some specifications. Understanding these intricacies, you will take the first step to answering the question of how to learn to read a wiring diagram.

Also you must know that all of the characters necessarily contain some alphanumeric abbreviations that displays some data parameters of the circuit elements. A separate topic are the various lines which represent electrical wiring. Basically use the following lines:

The origin of the Slavs. The influence of different cultures

• Depicts a thick solid wire, cables, tires, coil, resistors, capacitors, etc.;
• Double thick solid line represents the cores and the connection with the body;
• Bar fat – displays a grid of various electronic devices;
• Bar slim – the line represents the mechanical connection and shielding for electrical circuits.

Knowledge of the values of the above signs can play a key role in the response to the question of how to read a wiring diagram. However, another important subtleties conditional alphanumeric abbreviations that the rules are written as a sequence of letters, numbers and symbols on one line with no spaces. Positional notation often consists of three parts: the type of element, its number and function.

Letter codes types of elements are groups, which are given certain values. They can be one - or two-letter. All of them are detailed in technical documentation and the reference literature, where a deployed given all the parameters of the items that the diagrams are shown with this symbol. By the way, if you're interested in how to read electrical diagrams of the car, you can be sure that for them, this principle remains the same, because almost all documents of this kind are prepared using a common standard.

However, not all so is simple. There are many special schemes where it is sometimes difficult to understand even for professionals. Here, a knowledge of symbols is not enough. Should be well versed in all the intricacies of this device. To understand and remember the symbols and alphanumeric abbreviations are not difficult, but they can give an idea only about the device, but not on its principle of operation. It requires at least a minimal theoretical basis.
