  • Patent number: 9130446
    Abstract: An electrical slip coupling assembly and method for enhancing transmission of torque are provided. The coupling assembly includes a field member (FM), an armature member (AM), and annular windings. The FM includes flux concentrating axial and radial teeth. The AM includes an interchangeable non-ferrous electrically conductive material cladding on an axial inner surface of the AM and a relatively low conductivity ferrous material cladding on a radial inner surface of the AM. The excitation of the annular windings induces the axial teeth and the radial teeth to generate flux field concentrations that create an axial eddy current zone (AECZ) in the AM across an axial air gap, and a radial eddy current zone (RECZ) in the AM across a radial air gap. During relative motion between the FM and the AM, the eddy currents in the AECZ and the RECZ create a driving torque between the FM and the AM.

  • Patent number: 8482903
    Abstract: A front accessible metal clad switchgear assembly comprising multiple compartments defined within an electrical enclosure is provided. The compartments interchangeably accommodate electrical components, for example, current transformers, a circuit breaker, a control power transformer, an epoxy encapsulated potential transformer, etc., and bus bars in predetermined positions for allowing front access to the electrical components and bus bars. The front accessible switchgear assembly further comprises a plenum chamber rearwardly positioned in the electrical enclosure and in communication with the compartments to provide an exit path for releasing pressure and gases. A mounting block assembly is positioned in one or more of the compartments for mounting, enclosing, and providing front access to the electrical components. The mounting block assembly is configured to reduce temperature rise in the compartments.

  • Patent number: 8451589
    Abstract: A metal clad switchgear assembly comprising multiple compartments defined within an electrical enclosure is provided. The compartments interchangeably accommodate electrical components, for example, current transformers, a circuit breaker, a control power transformer, an epoxy encapsulated potential transformer, etc., electrical cables, and bus bars in predetermined positions for allowing front access and/or rear access to them. One or more compartments are configured for enabling the electrical cables to enter into and/or exit out from the electrical enclosure for allowing front and/or rear access to the electrical cables. A mounting block assembly is positioned in one or more of the compartments for mounting, enclosing, and providing front access to the electrical components.
