Što je monitor sustava uzemljenja i njegove značajke
The biggest blind spot of the grounding system lies in the invisible grounding wires and grounding rods under the ground, or the grounding wires in the wall or under the work table. The problem is often overlooked by people; and the general measurement is only limited to the measurement on the ground, and it is impossible to go deep into the ground to make a real-time accurate and complete measurement.
"Grounding" is the most economical and effective way to eliminate static electricity. A complete and effective grounding should include grounding and grounding, and must be monitored 24 hours a day to avoid bad grounding (or open circuit) and still be aware of "blind spots" "Or in an environment with high human error or a high-production value work area that is extremely sensitive to electrostatic damage, extra caution must be taken to prevent the expensive electrostatic protection measures already installed on the ground from falling short.
Prema najnovijoj specifikaciji ANSI/ESD S20.20 Američke udruge za elektrostatičku zaštitu i najnovijoj specifikaciji IEC-61340 Europske udruge za elektrostatičku zaštitu, jasni zahtjevi za elektrostatičko uzemljenje u području elektrostatičke zaštite (EPA) trebali bi osigurati učinkovito elektrostatičko uzemljenje u svakom trenutku, Potpuna usklađenost s ovim zahtjevom s ovim jedinstvenim digitalnim, 24-satnim monitorom elektrostatičkog sustava uzemljenja.
Značajke monitora sustava uzemljenja:
1,24 sata kontinuirano praćenje instrumenta funkcije nadzora uzemljenja, LCD može prikazati trenutni datum, vrijeme i vrijednost otpora uzemljenja u stvarnom vremenu.
2. Automatska funkcija alarma, praćenje u stvarnom vremenu i alarm statusa sustava uzemljenja.
3. The monitoring resistance value of the grounding system is adjustable (0-1999Ω). When the loop resistance of the ground wire is higher than the set value, it will immediately alarm with sound and light. The instrument can upload the quantity to the computer through RS485, and the computer will display what date and what date. Time, the size of the resistance value to the ground, the offline instrument has an automatic storage function (the software needs to be purchased separately).
4. Kada je sustav uzemljenja isključen, aktivira se zvučni i svjetlosni alarm, koji učinkovito poboljšava pouzdanost sustava uzemljenja, te je pogodan za radna mjesta koja zahtijevaju visoke vrijednosti otpora uzemljenja.
5. Jednostavan za korištenje, nema potrebe za zakopavanjem pomoćnih objekata za uzemljenje.
6. It can overcome the blind spot of grounding measurement, completely measure the real grounding impedance on and under the ground, and avoid electrostatic damage and electric shock.
