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

Quenching Medium - an overview | ScienceDirect Topics

Sulphur hexafluoride is an electronegative gas which has come into wide use as a dielectric (in X-ray equipment, in waveguides, coaxial cables, transformers, etc.) and as an arc-quenching medium in circuit-breakers. Its electric strength is of the order of 2.3 times that of air or nitrogen, and at a pressure of 3−4 atm it has an electric strength similar to that of transformer oil at atmospheric pressure.Get price

Different media for quenching metal explained | Paulo

Severity of QuenchantsCausticsOilsMolten SaltGasDiligence in Heat TreatingThe severity of a quench refers to how quickly heat can be drawn out of a part. Different quenching media have different degrees of severity. Caustics are the most severe quenchants, followed by oils, then salts and, finally, gases. The makeup of metal parts and the specified hardness to be achieved dictate which quenching mediumis used. Generally, low-hardenability parts made from carbon steel and low-alloy steel require more severe quenches to achieve a specified hardness. High-alloy steels, which are much more hardenable, are best quenched in less severe media.Get 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

Application Areas - Arcteq

The AQ-1000 arc quenching system is designed to limit the total arcing time to 5 ms and to minimize (or even eliminate) the damaging effects caused by the arc fault’s temperature and pressure. In most applications this will result in an energy release of less than 1 cal/cm². AQ-1000 is fully reusable which allows for full system testing on site. AQ-1000 is used in conjunction with the AQ-100 arc protection system.Get price
