How does an electric discharge work?Application?
Tungsten discharge needle
A pointed metal needle used to generate discharge or eliminate static electricity is widely used in static eliminators, lightning arresters, and plasma generators.
The main applications of electric discharge needles include:
1. Medical applications: Tungsten needles, especially pointed tungsten needles, can transmit the arc waveform from the electrosurgical generator to a very small area of action, ensuring surgery and precise cutting even at extremely low power.
2. Resistance welding: High melting point and stability: Due to their high melting point (approximately 3410℃) and excellent stability, tungsten needles can maintain their shape under high-temperature arcs, ensuring the stability and quality of the welding process.
3. Semiconductor manufacturing: Tungsten needles can be used to process probes, pin headers, and other components for semiconductor devices.
4. Static electricity elimination: Tungsten needles, with their wear-resistant and oxidation-resistant properties, are ideal materials for manufacturing static electricity elimination components such as discharge needles, ionizer emitters, and ion snake discharge needles.
Discharge needles utilize the tip effect to strengthen the local electric field, ionizing the air to generate corona discharge, thereby releasing charges, eliminating static electricity, or generating plasma. Regardless of the application, tungsten discharge needles play a crucial role in the field of discharge.
