It is easier to understand how to look at the electrical wiring diagram.

How to read the electrical wiring diagram is easier to understand as follows:

1 First of all, learn to read the circuit diagram, and be sure to remember the commonly used electrical text symbols and graphic symbols clearly. For example, FU stands for fuse, FR stands for thermal protector and QF stands for air switch. Only by understanding the meaning of these words and figures can we know what is marked in each position on the map.

2. When we understand these symbols and know their meanings, when we look at the circuit diagram, we should also learn the direction and distribution principle of the circuit, so that we can clearly understand the configuration requirements of each control on the circuit and not make mistakes.

3. In addition, on the premise of understanding the circuit symbols and circuit principles, we should also understand the functions and functions of the actual accessories or motors marked in the circuit, so as to understand the meaning and requirements of the drawings more clearly. Therefore, if you want to understand the circuit diagram quickly, there is no shortcut. We need to learn electrician knowledge and circuit principle step by step in order to truly understand electrician circuit diagram.

The circuit diagram is composed of various electronic components. To learn to understand the circuit diagram, we must first understand the structure and function of various components in the diagram, and then we can correctly understand the working principle of the circuit diagram. For example, high-voltage disconnectors, fuses, voltage transformers and lightning arresters are commonly used in high-voltage power supply circuits; Various relays, contactors and control switches are usually used in low-voltage circuits. Various diodes, transistors, capacitors, thyristors and various integrated circuits are commonly used in electronic circuits.
