What is a schema and what you need to know for reading schemas
To read the diagram is to draw from it the information necessary to perform a particular job. So, for example, if it is necessary to calculate the short-circuit current, reading the circuit is reduced to retrieving the data from it for calculation. In other cases, it is necessary to read the diagram to: understand the operation principle of the electrical installation; To clarify the purpose of one or another of its elements; Determine what to connect with; Find a false chain and find a way to eliminate it; To check whether the mode of operation is set correctly, etc. In a word, a lot of tasks that are solved as a result of reading the schemes are many, and these tasks are not only different, but also diverse. Accordingly, the methods by which the schemes are read are varied and varied.
Reading schemes should be prepared, ie, accumulate the necessary minimum knowledge, just as before reading the text you need to study the alphabet, the rules of word formation and word combinations.
What is a circuit? The word scheme is used in several meanings.
1. The scheme is a design document (a kind of drawing) in which the component parts of the product - its elements and connections between them are shown conditionally, without observing the scale. For example, the elements of the electrical circuit are resistors, lamps, transformers, motors and other electrical products. Conductors are the connections between them.
2. A schema is also called an object or a set of objects, for example an integrated circuit, etc.
3. When they say: the circuit is working, the circuit is faulty, the circuit element is overheating, then it is clear that this is not a drawing, but the electrical installation itself. Indeed, a resistor (circuit element) can overheat, but not its image. In a word, the electrical installation and its scheme are far from the same, just as they are not the same, the machine and its drawing.
Under the word scheme, as a rule, it means not the actual drawing, but what is depicted on it.
