What is the testing period for high-voltage discharge rods?

1, The function and classification of discharge rods
A discharge rod is a device used to prevent static electricity, mainly applied in places that are susceptible to static interference or sensitive to static electricity, such as hospital operating rooms, spacecraft production workshops, semiconductor factories, etc. The discharge rod can eliminate static charges generated by the surrounding environment through contact and discharge of conductors, thereby ensuring the normal operation of the equipment.
According to their structural form and working principle, discharge rods can be roughly divided into several categories such as tubular, rectangular, and needle shaped. Among them, the tubular discharge rod is suitable for large-area conductive treatment, such as walls, floors, etc; Needle discharge rods are suitable for local electrostatic treatment, such as on the surface of workpieces.
2, Test cycle of discharge rod
In order to ensure its effectiveness and service life, the discharge rod needs to be tested and replaced regularly. Generally speaking, the testing cycle for discharge rods is 1 or 3 years, depending on the actual situation and manufacturer's requirements. The experimental content mainly includes: checking whether there is corrosion, aging, damage, etc. on the surface of the discharge rod; Measure whether the resistance value of the discharge rod meets the standard; Test whether the discharge performance of the discharge rod is normal.
If quality problems are found in the discharge rod during the experiment, it needs to be replaced in a timely manner. At the same time, the discharge rod also needs to be maintained during use, with regular cleaning of surface dirt to avoid moisture, heat, and exposure to sunlight, in order to ensure its long-term effective anti-static effect.
