What does the circuit system include?

1. However, no matter how complex the circuit system is, it is also composed of power supply, circuit protection device, control device, electrical equipment and wires. Automobile circuits are usually composed of power supply circuits, start circuits, ignition circuits, lighting and light signal device circuits, instrument information system circuits, auxiliary device circuits and electronic control system circuits.

2. Circuit: a closed loop composed of power supplies, wires, switches and electrical appliances. Among them, power supply: provide electricity;Wire: transmit electricity; switch: control the connection and disconnection of circuits or electrical appliances; electrical appliances: consume electricity. Circuit: A conductive circuit composed of metal wires and electrical and electronic components is called a circuit.

3. Such as electric lamps, electric motors, electric furnaces, etc. The intermediate link is the part that transmits, distributes and controls electrical energy. It is connected to the power supply at one end and the load at the other end. The simplest intermediate link is to connect wires, lights and fuses, or it can be a relatively complex network or system.

What is the main function of the automobile circuit system?

1. The main function of the automobile circuit system: to convert the electrical energy of the battery into mechanical energy through the starter and start the engine. Modern automobile engines use electric motors as the starting power.It is composed of storage battery, ignition switch, starting relay, starter, etc. Start the switch.

2. Most of the automobile circuits are DC circuits. Function: First, it can transmit and distribute electrical energy to achieve mutual conversion with other forms of energy. The second is to realize the transmission and conversion of signals, and carry out the transmission, exchange and processing of signals. The circuit is the path through which the current passes, forming a closed loop.

3. The function of the automobile power supply system is to provide low-voltage DC power supply to all electrical equipment in the automobile (usually 12V for gasoline vehicles and 24V for diesel vehicles) so that all parts of the automobile can work normally; batteries, generators and automotive electrical equipment are all connected in parallel.

4. Function: Provide uninterrupted power supply for car users, provide power, and meet the needs of users.For electrical equipment with different voltages and uses, when there is no special requirement, only a general grounding body is usually needed, adhering to the principle of equipo-potential connection, and connecting the metal pipes and components of the building to the total grounding body.

5. The vast majority of automotive circuits are DC circuits. Function: First, it can transmit and distribute electrical energy to realize the mutual conversion with other forms of energy; second, it can realize the transmission and conversion of signals for the transmission, exchange and processing of signals. The circuit is the path of the current to form a closed loop.

6. The function of the automobile circuit is that when the current of the line is too large due to overload and short circuit failure, the protection device automatically disconnects the power supply circuit to prevent the line or electrical equipment from burning out.

Component to the system, how to establish a system equivalent circuit

1. According to the actual connection, replace all components with equivalent impedance, which is the equivalent circuit diagram. Circuit: A conductive circuit composed of metal wires and electrical and electronic components is called a circuit. Add a power supply to the input end of the circuit to generate an electric potential difference at the input end, and it can work when the circuit is connected.

2. Head and tail connection method, current flow method.If the head and tail are all connected, they must be connected in series. If the head is connected, the tail and the tail must be connected in parallel. If there is a connection of both the head and the end, and the first prime minister, it must be a mixed connection. According to the flow direction of the current, the characteristics of series and parallel are judged, and the series, parallel and hybrid circuits are judged.

3. Analyze the electromagnetic relationship of synchronous generators. The rotor of the synchronous generator generates an induced electromotive potential under the action of the magnetic field, thus generating an electric current. The magnetic field generated by this current will affect the distribution of the rotor's magnetic field and form an electromagnetic relationship. Derive the equivalent circuit of the synchronous generator.

4. The equivalent circuit analysis of the long line of the power system is as follows: short line: short line refers to an overhead transmission line with a length of no more than 100km and a voltage of no more than 60kV; or a cable line with a voltage of less than 10KV. The equivalent circuit of the short line is represented by a centralized parameter circuit and ignores the inductive The influence of the branch road.

Which relatively independent subsystems are generally composed of the whole car circuit?

The relatively independent systems of automobile circuits include: power supply circuit, start circuit, ignition circuit, lighting and lighting signal device circuit, instrument information system circuit, auxiliary device circuit and electronic control system circuit.

2 Start the system. It is mainly composed of three parts: starting the DC motor, power transmission and control switch. Because the three parts are generally made into one, it can also be called a starter. 3 Ignition system. Use a new electronic ignition system to replace the traditional battery ignition.

Which parts of the automobile circuit make up the automobile circuit mainly includes electricity.Source circuit, start circuit, ignition circuit, lighting and lighting signal device circuit, instrument information system circuit, auxiliary device circuit and electronic control system circuit.

Starter system: The main part is the starter, and its task is to start the engine. ( 2) Ignition system: It is a component of a gasoline engine, including all components of an electronic ignition system or a traditional ignition system. Its task is to generate high-pressure electric sparks and point the combustible mixture in the gas cylinder according to the working order of the engine.
