International Classification:

H01H 6702

US Classification:

335132

Abstract:

A switchgear module is provided that is assembled from one or more molded housing portions to provide a gas-tight volume for the housing of electrical components. The switchgear modules include provisions for assembly of various combinations of switchgear modules into a variety of electrical circuit configurations while maintaining a gas seal of the switchgear modules. In a preferred arrangement, the switchgear module includes bus conductors that are integrally incorporated during the molding of the switchgear module housing and that are accessible from opposite sides of the module. Further, the switchgear module includes integrally molded features for providing access to make electrical interconnections between the bus conductors of adjacently positioned switchgear modules. Thus, the finally assembled and tested switchgear modules with pressurized internal volume may be configured to provide a variety of different electrical circuit combinations of the internal components and are also capable of being reconfigured as desired into different configurations or lineups without the loss of the seal of the interior volume of the switchgear modules. The switchgear module includes a complete internal and integral system to satisfy desirable operating practices to deenergize, test and ground the circuit before working thereon.

International Classification:

H01H 3302

US Classification:

200400

Abstract:

A fault interrupter is provided that includes a high-speed disconnect in series with an interrupter wherein the circuit opening is via the interrupter and the circuit making is via the disconnect. A stored energy disconnect operating mechanism operates the disconnect between ground, open and closed positions and also charges the interrupter mechanism during a slow opening of the disconnect without fully charging the disconnect operating mechanism. Thus, the required operating forces to open the disconnect and charge the interrupter mechanism are reduced. During a manual opening, the disconnect operating mechanism trips open the interrupter, then only partially charges to begin opening the disconnect before releasing the stored energy. Continued operation of the disconnect operating mechanism slowly drives the disconnect open while charging the interrupter mechanism and closing the interrupter. The interrupter mechanism remains charged during operation of the disconnect between the open and ground positions by the disconnect operating mechanism.
