In our age of total electronics and electrification, various equipment that uses current in their work has become not only the property of large enterprises and power networks, but also home appliances. In this regard, the question of how to read electrical circuits is of interest to many. Understanding the basic principles of constructing circuits, the electrical processes that take place in them, and standard graphic symbols, you can easily read almost any drawing of this kind.
Before reading electrical circuits, it is necessary to understand their structure and construction principles well. And then even the most complex and intricate scheme will no longer seem like just a meaningless set of "kabbalistic symbols" and ornate patterns. And the question of how to read electrical circuits will become resolved.
All graphic symbols are characterized by a rather simple form of outline. Theyfeatures contain the most characteristic features and characteristics of each component, which greatly facilitates their memorization. Symbols do not reflect the dimensions of the element, but only its type and some technical characteristics. Having understood these intricacies, you will take the first step towards answering the question of how to learn to read electrical circuits.
It is also necessary to know that all symbols necessarily contain certain alphanumeric abbreviations that display some parameters of these circuit elements. A separate topic is a variety of lines that symbolize electrical wiring. The following line types are mainly used:
- thick solid depicts wires, cables, tires, windings, resistors, capacitors, etc.;
- solid double thick line indicates cores and body connections;
- dashed thick - displays a grid of various electronic devices;
- thin dashed line - depicts mechanical connection and shielding lines on electrical diagrams.
Knowing the meaning of the above symbols can play a key role in answering the question of how to read electrical schematics. However, the subtleties of conditional alphanumeric abbreviations are no less important, which, according to the rules, are written as a certain sequence of letters, numbers and symbols in one line without spaces. Positional designation often consists of three parts: element type, its number and function.
Letter element type codes are groups that are given specific meanings. They can be one or two letters. All their values are detailed in the technical documentation and special reference literature, where all the parameters of the elements that are depicted in the diagrams by this symbol are given in great detail. By the way, if you are interested in how to read the electrical circuits of a car, then you can be sure that this principle remains unchanged for them, since almost all documents of this kind are drawn up according to a single standard.
True, not everything is so simple. There are many special schemes that are sometimes difficult to understand even for professionals. Here, knowledge of conventional notation alone is not enough. You need to be well versed in all the intricacies of the operation of this device. Understanding and remembering symbols and alphanumeric abbreviations is not difficult, but they can only give an idea of the device's device, but not about its principle of operation. This already requires at least a minimal theoretical basis.
