US20050150870A1 - Arc-quenching device for circuit breakers

The present invention relates to an arc-quenching device for circuit breakers having double-break contacts for use in low-voltage distribution systems. Provided around a prechamber ( 41 ) is a magnetic shield ( 91 ) for the purpose of intensifying the magnetic blowing action on an arc formed between the arc guide rails ( 51, 61 ) of the prechamber.Get price

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

Simulation of Arc Quenching in Hermetically Sealed Electric

Apr 03, 2018 · Rapid arc quenching is an essential quality of state-of-the-art high-voltage mechanical relays in electric vehicles. As a relay begins to break electrical contact, strong arcing can occur. This delays the process of sending a signal to the primary circuit breaker to isolate the load from a sudden current surge.Get price

Methods of Arc Extinction in Circuit Breaker

Therefore, dielectric strength of the medium between the contacts can be increased by cooling the arc (iv) blast effect : If the ionised particles between the contacts are swept away and replaced by un-ionised particles, the dielectric strength of the medium can be increased consider-ably. This may be achieved by a gas blast directed along theGet 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

Power distribution | Power Generation and Distribution

In 1930, Siemens introduced a fluid circuit breaker that used water as the arc quenching medium. In this "expansion circuit breaker," the arc that occurred during switching evaporated some of the surrounding water. This caused high pressure to develop, which would cool or extinguish the arc if the flow was designed right.Get price

Arc Fault Quenching for Mission Critical Systems | SBIR.gov

Solid state circuit breaker technology can enhance existing arc fault detection technology by providing a higher tolerance to nuisance tripping and by providing an opportunity to maintain some reduced level of control in the event of an electrical fault.By the appropriate control of power MOSFETs, power may be quickly removed upon the detection of an arc and quickly restored upon theGet price
