The following measures can be taken to protect tungsten wire through circuit design:
- Voltage and current protection
Stabilize voltage: Ensure that the voltage in the circuit is stable to avoid excessive voltage fluctuations that may impact the tungsten wire. A voltage stabilizer or voltage regulator can be used to maintain the voltage at a constant level.
Limit current: Set a suitable current limiter in the circuit, such as a fuse or current limiting resistor, to prevent the tungsten wire from overheating and burning due to excessive current.
- Overload and short-circuit protection
Overload protection: Use an overload protector or thermal relay to monitor the current in the circuit. When the current exceeds the set value, these devices automatically cut off the circuit to prevent the tungsten wire from being damaged by overload.
Short-circuit protection: Install a short-circuit protector, such as a fuse or circuit breaker, in the circuit. When a short circuit occurs in the circuit, the short-circuit protector will quickly cut off the circuit to prevent the short-circuit current from causing further damage to the tungsten wire and the circuit.
- Thermal management and heat dissipation design
Heat dissipation design: optimize the heat dissipation structure of the bulb, such as adding heat sinks, using high thermal conductivity materials, etc., to improve the heat dissipation efficiency of the tungsten wire and reduce its operating temperature.
Temperature monitoring: set a temperature sensor in the circuit to monitor the operating temperature of the tungsten wire in real time. When the temperature exceeds the safe range, an alarm can be triggered or the circuit can be automatically cut off to protect the tungsten wire.
- Other protection measures
Use high-quality tungsten wire: select tungsten wire materials with high purity, good high temperature resistance and creep resistance to improve its service life and stability.
Add protection components: add protection components such as capacitors and inductors to the circuit to filter out high-frequency noise and surge voltage in the current and protect the tungsten wire from damage.
Optimize circuit design: reasonably design the circuit layout and routing, reduce the resistance and inductance in the circuit to reduce energy consumption and heat generation, thereby reducing the burden on the tungsten wire.
- Precautions in practical application
Avoid frequent switching: Frequent switching of bulbs will cause the tungsten wire to be subjected to greater thermal shock and mechanical stress, thereby accelerating its aging process. Therefore, frequent switching of bulbs should be avoided as much as possible.
Choose the appropriate bulb specifications: Choose the appropriate bulb specifications and power according to the actual application requirements to ensure that the tungsten wire operates under normal working conditions and avoid overload or underload.
