Common circuit protection components include voltage regulators, overvoltage protectors, overcurrent protectors, fuses and discharge tubes, etc., which can ensure safe and stable operation of the circuit.
1. Voltage regulator
A voltage regulator is an electronic component whose main function is to provide a stable voltage output in a circuit. Due to fluctuations in grid voltage and load changes, the output voltage in the circuit will change, and the voltage regulator can compensate for this voltage fluctuation to ensure that the output voltage in the circuit always remains stable. Common voltage regulators include voltage stabilizing diodes, voltage stabilizing modules, and adjustable voltage regulators.
2. Overvoltage protector
An overvoltage protector is an electronic component used to protect circuits from overvoltage damage. When the input voltage in the circuit is higher than the rated voltage, the overvoltage protector will automatically cut off the circuit to prevent damage to the circuit due to overvoltage. Overvoltage protectors can protect electrical equipment, electronic products, and industrial production equipment.
3. Overcurrent protector
Overcurrent protectors are mainly used to protect circuits from overcurrent damage. When the current in the circuit exceeds the rated current, the overcurrent protector will automatically cut off the circuit. Overcurrent protectors are widely used in electrical appliances, electronic equipment, production equipment and other fields in circuits to ensure the safe operation of equipment.
4. Fuse
A fuse is an electronic component used to protect circuits. When the current in the circuit exceeds the rated current, the fuse will cut off the circuit in a short time to prevent the circuit from being damaged by overload or short circuit. Fuses are widely used in household circuits, power transformers and machinery and equipment.
5. Discharge tube
A discharge tube is an electronic component used to protect circuits from overvoltage damage. When an excessive voltage pulse occurs in the circuit, the discharge tube will automatically turn on and disperse the overvoltage to the ground wire. Discharge tubes are widely used in electronic products, communication equipment, computers, power grids and other fields, and can effectively protect equipment from overvoltage damage.
The above are several common circuit protection components. They can protect the circuit from damage by factors such as overvoltage and overcurrent, and ensure the safe and stable operation of the circuit.
