In the process of transformer design and manufacturing, various circuit diagrams are inseparable. The circuit diagram can help us quickly understand the functions and components of this transformer. So do you know how to understand the circuit diagram of a transformer?

First of all, in the first step, we must clearly understand various electronic components. The symbols of these components are fixed. You can find out which electronic components are used in the circuit diagram by looking at the table.

Of course, looking at a circuit diagram is not simply a combination of components. If you want to quickly understand the meaning of the circuit diagram, it is best to start with the area analysis. That is, all circuits are considered to be in a powered state, and their main circuits, control circuits and controlled execution units, as well as power sources, loads, connecting wires and auxiliary equipment in the circuit are analyzed.

According to this principle, there are several ways to help us understand the circuit diagram.

1. Reduce complexity into simplicity

Split each system and only read the parts you need to improve reading efficiency.

2. The main loop, control loop and execution circuit are separated

According to the above principles, find their main loop, control loop and execution line, and process them separately to simplify the difficulty of reading the circuit diagram. Usually, the main circuit is connected by power input, air switch, fuse, knife switch, contactor and load. The control circuit is one end of the coil winding, and the execution circuit is one end of various relays.

3. Organize according to the circuit: that is, understand which line comes from where and where it goes to form a complete closed loop.

4. Clarify the common parts: Some control executions are linked, including self-locking or interlocking. These require the use of normally closed, normally open contacts or thermal relays connected in series with some protective devices.

5. Use reverse thinking: For complex circuits, we will use reverse thinking to analyze. First find the electrical appliance, then look for its control switch in sequence against the direction of the current, connect the control unit, and finally reach the controlled electrical component.

The above are five commonly used methods and techniques for reading circuit diagrams. Are they very practical? Of course, although there are tips for reading circuit diagrams, there is no shortcut. We still need to read more and practice more.
