The electrical breakdown phenomenon of tungsten wire can be avoided by the following methods:
- Material selection and optimization
High-purity tungsten wire:
Using high-purity tungsten wire material and reducing the impurity content can improve the breakdown voltage and electrical properties of tungsten wire.
Alloying treatment:
Through alloying treatment, the microstructure and performance of tungsten wire are improved, and its ability to resist electrical breakdown is improved. For example, adding a small amount of rare earth elements can improve the toughness and oxidation resistance of tungsten wire.
- Process improvement
Fine processing:
Use fine processing technology to ensure the dimensional accuracy and surface finish of tungsten wire, and reduce the risk of electrical breakdown caused by improper processing.
Heat treatment:
Through appropriate heat treatment process, optimize the microstructure of tungsten wire and improve its electrical and mechanical properties. For example, annealing can eliminate the residual stress inside the tungsten wire and improve its toughness.
- Electric field uniformity design
Uniform electric field:
When designing the circuit, ensure that the electric field is evenly distributed to avoid electrical breakdown caused by excessive local electric field strength. This can be achieved by optimizing the electrode shape, adjusting the electrode spacing, etc.
Insulation protection:
Set an insulating layer or insulating medium around the tungsten wire to increase the breakdown voltage of the tungsten wire and prevent the occurrence of electrical breakdown.
- Power supply control
Stable power supply:
Use a stable power supply to ensure that the fluctuations of voltage and current are within the allowable range and reduce the risk of electrical breakdown caused by unstable power supply.
Current limiting protection:
A current limiting protection device is set in the circuit. When the current exceeds the set value, the power supply is automatically cut off to prevent the tungsten wire from breaking down due to overcurrent.
- Monitoring and maintenance
Real-time monitoring:
Use real-time monitoring technology to monitor the working status of the tungsten wire, and promptly discover and deal with potential electrical breakdown risks.
Regular inspection:
Regularly inspect and maintain the tungsten wire, including cleaning the surface dirt, checking whether the insulation layer is intact, etc., to ensure that the tungsten wire is in good working condition.
