Embodiment Construction

[0034] figure 1 Components of an exemplary circuit interrupter 100 having a magnetic arc extinguishing feature are shown in accordance with aspects of the present invention.

[0035] Circuit interrupter 100 may be any device that can be used to close and open an electrical circuit. For example, it will be apparent to those skilled in the art that circuit interrupter 100 may include a switch, or may be implemented as a circuit breaker.

[0036] Circuit interrupter 100 includes stationary contacts 110 that are electrically connected to line terminals (not shown). The line terminals receive power from a power source (not shown), which in some applications is provided by a power company. However, those skilled in the art will appreciate that electrical power may be provided and conditioned by any commercial device including, but not limited to, commercial power grids, generators, solar panels, fuel cells, and the like.

[0037] The movable contact 120 is disposed on a movable c...

Abstract

A circuit interrupter including an arc extinguisher which functions to arrest an arc that develops between electrical contacts. The circuit interrupter includes a permanent magnet coupled at opposite ends to two magnetically permeable pole pieces that are configured to drive or urge an arc into toward an arc extinguisher. The device allows for arc motivation due to the magnetic field without requiring the use of electrical power and allows for a rugged, light-weight design.

Description

technical field [0001] The present invention relates generally to the protection of electrical devices, and more particularly to an arc extinguishing structure configured to quickly extinguish an arc using fewer components than known methods to reduce manufacturing costs and provide a more compact, lighter weight device. Background technique [0002] A circuit interrupter is an electrical component used to break an electrical circuit, interrupting the flow of electrical current. One example of a circuit interrupter is a switch, which typically includes two electrical contacts in a closed state or an open state to close or break an electrical circuit. [0003] Another example of a circuit interrupter is a circuit breaker. Circuit breakers may be used, for example, in electrical panels to limit the amount of current allowed to flow through attached electrical wiring. Circuit breakers are designed to protect electrical circuits from damage caused by various dangerous fault co...
