The electrical control system is generally called the secondary control loop of electrical equipment, different equipment has different control loops, and the control methods of high-voltage electrical equipment and low-voltage electrical equipment are also different. Specifically, the electrical control system refers to the combination of several electrical components to complete the control of a certain or certain targets, so as to ensure the safe and reliable operation of the controlled equipment, and its main functions are: active control, maintenance, monitoring and measurement.

What are the components of an electrical control system? The basic circuit of the commonly used control line consists of the following parts.

1. Power supply circuit: The power supply of the power supply circuit includes AC380V, 220V and DC 24V.

2. Maintenance circuit: The operating power supply of the maintenance (auxiliary) circuit has single-phase 220 communication, 36V DC, or DC 220 communication, 24V DC, etc., which carries out various maintenance such as short circuit, overload and loss of voltage for electrical equipment and lines, and is composed of maintenance components such as fuses, thermal relays, loss of voltage coils, rectifier components and voltage stabilizing components.

3. Signal circuit: a circuit that can reflect or display the normal and abnormal operation status information of equipment and lines in a timely manner, such as signal lights of different colors, audio equipment with different sounds, etc.

4. Active and manual circuits: In order to improve the efficiency of electrical equipment, there are generally active links, but in the installation, commissioning and handling of urgent matters, manual links are also required in the control lines for debugging. The conversion of active and manual methods is completed through combination switches or conversion switches.

5. Brake parking circuit: block the power supply of the circuit, and take certain braking measures to make the motor park quickly in the control link, such as energy consumption braking, power supply reverse braking, reverse pull braking and regenerative power generation braking.

6. Self-locking and locking circuit: After the starting button is released, the line insists on energizing, and the electrical link where the electrical equipment can continue to operate is called the self-locking link, such as the dynamic contact of the contactor is connected in series in the coil circuit. In order to ensure the safety and reliability of the operation of two or more electrical equipment and components, only one can be powered on, and the other can not be powered on. For example, the dynamic breaking contacts of two contactors are separated from each other in series in the coil circuit.
