摘要： Effective arc-quenching is desired for current interrupters as defined to include circuit breakers, contactors, fuses and the like under conditions of operation where an electrical arc is produced that must be quenched to eliminate an undesirable current flow. An improved mode of arc-quenching coatings comprising urethane, melamine and acrylic based resin compositions containing inorganic nitrides such as boron nitride, aluminum nitride and silicon nitride are found to be effective as arc-quenching materials for current interrupters. Other coating compositions comprising urethane, melamine and inorganic nitrides mentioned above and high nitrogen organic compounds such as urea, hydantoin, allantoin, guanidine carbonate, guanine, melamine cyanurate and 1,3-diphenyl guanidine are also found to be effective as arc-quenching materials for current interrupters.

摘要： A circuit breaker has a magnetic trip assembly which can be adjusted to trip the breaker for low level overcurrents in the range of five to ten times rated current. The magnet trip includes for each pole of the breaker a helical torsion spring having one torsion arm which biases an armature against an adjusting bar to form a gap between the armature and a stationary magnetic structure in which magnetic flux strong enough to attract the armature and trip the breaker is induced by overcurrent. A second torsion arm of the spring has a first portion which bears against and slides along a pivot member carried by the adjusting bar to adjust the bias force applied to the armature by a given amount per unit travel of the adjusting bar over a low trip current portion of the range of travel of the adjusting bar. A second terminal portion of the second torsion arm of the spring extending at an angle from the first portion engages and slides along the pivot member on the adjusting bar to provide a greater change of bias force per unit travel of the adjusting bar at the higher trip current settings. Movement of the adjusting bar adjusts the spring bias for all poles of a multiphase circuit breaker simultaneously. The gaps between the armatures and the fixed magnetic structures of all the poles can also be adjusted by camming surfaces on the adjusting bar.

摘要： The arc plates of an arc chute assembly for a circuit breaker are supported in spaced, stacked relation by a structural shell molded of a gas evolving resin. Generation of arc gases, that cool the arc thereby increasing the current interruption capability of the breaker, can be further enhanced by gas evolving additives included in the resin. Arc gas flow is increased to further cool the arc by molding the interior walls of the structural shell to form venturies between the arc plates. One or more elongated fibers wrapped around the stack of arc plates in an oval strengthen the structural shell to withstand the increased pressure generated by the high arc gas volume.

摘要： A shorting switch eliminates arcing faults in low voltage power distribution equipment. The switch includes a base supporting a first side and an opposite second side. A first end of a spring engages the first side of the base. A first end of a release bolt engages the first side of the base. An electrically activated, chemical charge is disposed in an opening of the release bolt to fracture that bolt. A bridging contact is biased by a second end of the spring toward the second side of the base. A second end of the release bolt normally holds the bridging contact and maintains the spring in a compressed state. Two contacts are supported by the second side of the base for electrical engagement by the bridging contact after fracture of the release bolt. Two terminals are respectively electrically connected to the two contacts.

摘要： A mechanical coupling device for connecting together two aligned fiberglass reinforced plastic duct sections, each having a terminal end portion of equal diameter, so as to form a leak proof joint that is resistant to fire and also chemical corrosion from gases and/or condensate within the duct sections is disclosed. The device comprises elements that cover and seal the terminal end portion of each said duct section; a central gasket member that covers the end elements and extends around the terminal end portions of the duct sections; a flexible metal sleeve member that surrounds the central gasket member; and tightening devices on the sleeve which compress the central gasket member and hold the aligned adjoining duct sections together to provide a leak-proof joint. The tightening devices are spring driven so that if the bulk of the gasket member is reduced due to fire, the sleeve will maintain a firm non-slip hold on the duct joint. Different embodiments of the coupling device are disclosed using various configurations of the central gasket member and end elements as well as the use of intumescent materials in the gasket member or in a separate bag. The intumescent materials react to fire which may occur in the duct by swelling to further help the coupling device in maintaining a firm non-slip position on the duct joint during such fire conditions.

摘要： A circuit breaker is disclosed having a movable magnetic core provided in the magnetic trip assembly thereof adapted to lower the current levels at which the magnetic trip mechanism will operate. The magnetic trip assembly also includes a pivotally connected armature, a current carrying conductor, a fixed magnetic yoke and a latchable operating mechanism. A primary air gap exists between the armature and the fixed yoke. The movable core is designed to move into an extended position which reduces the primary air gap which in turn increases magnetic flux coupling which allows the magnetic force required for the armature to pivotally rotate to unlatch the operating mechanism and thereby trip the circuit breaker to be generated at a lower current level. This reduction in current is the desired effect of the new design.
