A modern car is a complex system of mechanisms. These days you will not surprise anyone with a machine “stuffed” with electronics. The on-board computer, the fuse box, which incorporates devices for breaking the circuit during a short circuit, various elements of security systems that allow the driver to be less stressed when the car moves in various conditions. The creators of these technical masterpieces work to ensure the safe operation of cars.
The fuse box is one of the important devices in the electrical system of cars. As you know, electrical energy is used to illuminate, start the engine, ignite the mixture in the engine, and more. The main sources are the battery and generator. To ensure the operability of the system, the car is "entangled" with a large number of wires connecting energy sources to consumers. It is worth noting that where there is electricity, there is an increased danger. In order to exclude the possibility of a short circuit, the electrical circuit must be opened on time. This function is performed by the fuses that are installed in the mounting block called the “fuse box”.
Any electrical circuit is designed for a specific current strength. This must be considered when choosing fuses. In the chain that has more powerful consumers, it is necessary to install more powerful devices. Otherwise, the fuse thermocouple will not withstand the heat load, which can damage even the fuse box.
What happens if you do not adhere to the above conditions? The electrical system will fail. Suddenly extinguished headlights at night, idle appliances, premature discharge of the battery - these are just a few problems that an ordinary motorist may encounter. To avoid such troubles, you need to monitor the health of the system as a whole. The main thing is surge protection. You need to take care of her constantly.
A constant voltage must be maintained in the vehicle’s power supply system. For this purpose, a special surge protection device is provided. Without a regulator, at high revolutions of the generator rotor shaft, the voltage increases many times. This can lead to burnout of lamps and other electrical equipment.
Electric equipment and car electronics are growing rapidly. The latest engine management systems allow you to save fuel and achieve maximum power with a minimum content of harmful chemicals in the exhaust gases. New ones appear and the old ones, tested in various operating conditions, of the system of directional stability, stabilization, and distribution of braking forces appear. The car is increasingly "overgrown" with security sensors, tracking, transmitting signals to the "electronic brain" for analysis and subsequent transmission of data to control mechanisms. All this, according to the designers, makes the car safe for the driver and others.
Here it is worth going back a little and remembering the surge. For electronic voltage-sensitive systems this is especially important! If the old "Lada" when braking receive a command only from the pedal, then in cars equipped with an electronic control system, various sensors and mechanisms take part. And if in case of emergency braking the control unit receives a “wrong” signal, it will issue an incorrect command to the actuator . In this case, the machine may be unsafe. Do not overvoltage in the circuit! And in case of malfunctions, contact the service center.
