What is quenching an arc? - Standex Electronics

When the reed contacts open they break a circuit. If there is a voltage and current present when the contacts open they will stop the current flow. Once the contacts open the voltage that was driving the current will reappear across the contacts. This is normally not an issue unless the voltage is generally higher than 250 volts. At this level and higher when the contacts attempt to open theyGet price

Micro-Arcing During High-Density Plasma Chemical Vapor

Background – The Basic Arcing MechanismResult: Contamination and Yield LossThe Challenge: Detecting Micro-ArcingRecovery from Micro-ArcingProactive Micro-Arcing ManagementSolutions to Increase Equipment Uptime and Factory EfficiencyThe plasma within the HDP process chamber is at a higher electrical potential than the chamber wall. Under some process conditions, dielectric breakdown occurs on the chamber wall, resulting in a discharge current from the highly concentrated, electric field of the plasma to the side wall of the chamber. Metal at the chamber wall vaporizes, releasing aluminum particles into the chamber and onto the wafer. The bare aluminum surface of the chamber wall becomes exposed, potentially setting the stage for subsequent micro-arcing events. Recipes that couple low pressure with high power are especially susceptible to micro-arcing (see figure 1). Figure 1 – Basic Arcing MechanismGet price

How Arc-Quenching Switchgear Improves Safety | Pumps Systems

Passive ProtectionActive ProtectionCurrent-Limiting Arc-Quenching SystemsConclusionSince the introduction of arc-resistant electrical equipment, the design paradigm has been to create a method of containing the energy from an arc flash event and redirecting it away from the operator. These methods typically include heavily reinforcing the electrical equipment enclosure using thicker-gauge steel, reinforced hinges and multipoint door latches to contain the arc energy and prevent enclosure fragmentation and burn-through. Mounted on top of the gear, plenums connected to ducts serve to redirect the arc gasses through the top of the equipment and out of the room. Such designs benefit from simplicity and acquisition costs. These passive arc-resistant designs require no electronics or electrical power to function. Minimal technological advancements were required to develop these designs. All that was needed was a more robust equipment enclosure. The incremental costs of such arc-resistant equipment remain relatively low, requiring only the addition of more steel and more...Get price
