Common incorrect anti-static methods

Common mistakes in anti-static methods in factories: 1. Lack of anti-static product testing instruments. The most common mistake is that many companies purchase a large number of anti-static products but do not purchase some commonly used anti-static product testing instruments. We know that every product has a certain service life and its quality varies. Without some commonly used testing instruments, we wouldn't know whether the product is damaged or of good quality. This way, it won't have an anti-static effect either. 2. Poor grounding connection method A. The anti-static system must have an independent and reliable grounding device. The grounding resistance is generally less than 10Ω, and the burial and detection methods should comply with the requirements of GBJ 97. B. The anti-static ground wire must not be connected to the power neutral wire and must not be shared with the lightning protection ground wire. Because phenomena such as lightning strikes can affect the performance of products and personal safety through circuits. C. When using a three-phase five-wire power supply system, the ground wire can be used as an anti-static ground wire (but the neutral wire and the ground wire must not be mixed). D. The cross-sectional area of the grounding main line should be no less than 100mm ². The cross-sectional area of the branch trunk line should not be less than 6mm ². The grounding wires for equipment and workbenches should be multi-strand plastic-coated conductors with a cross-sectional area of no less than 1.25mm ². The color of the grounding wire is preferably yellowish-green. E. The connection method of the grounding main line should adopt brazing. F. The connection terminals of anti-static equipment should ensure reliable contact, be easy to install and disassemble, and allow the use of various clamp-on connectors, such as alligator clamps, plugs and sockets, etc. For workplaces with high requirements for ground resistance values, grounding system monitoring and alarm devices should be installed, such as the SL-038A grounding system monitoring and alarm device produced by our company, which can monitor at any time whether the ground wire is in good contact with the earth. 3. Using anti-static products as ordinary products Many companies use anti-static products as ordinary products, thinking that as long as the products do not deform or crack, they can continue to be used. In fact, this
