Filed:

Apr 4, 2003

Appl. No.:

10/406570

Inventors:

Frank John Muench - Waukesha WI
Patrick Harold Pride - Mukwonago WI

Assignee:

McGraw-Edison Company - Houston TX

International Classification:

H01H 1958

US Classification:

200 11R, 200 11 TC

Abstract:

A make-before-break selector switch for use in high-voltage applications allows power to a load to be switched from a first power source to a second power source such that the second connection is made before the first is broken. The selector switch includes a blade coupled to a selector switch control such that the blade may be placed in a first position to electrically couple a first power source electrical contact to a load electrical contact and in a second position to electrically couple a second power source electrical contact to the load electrical contact. T-shaped and v-shaped blade implementations are examples of configurations that may be used.

Assignee:

Cooper Technologies Company - Houston TX

International Classification:

H01H 19/00

US Classification:

200 11TC

Abstract:

A transformer switch, such as a dual voltage switch or a tap changer. The switch includes a cover, a housing, and a rotor sandwiched between the cover and the housing. The cover and housing are molded from a non-conductive plastic. An interior space of the cover includes at least one pocket within which stationary contacts are disposed. Each stationary contact is electrically coupled to one or more windings of a transformer. The rotor extends within a channel of the housing, from a top of the transformer switch to an interior surface of the cover. The interior surface includes a protrusion about which the rotor and at least one movable contact coupled thereto can rotate. The movable contact is configured to be selectively electrically coupled to at least one of the stationary contacts. For example, different stationary contact-movable contact pairs can correspond to different voltages of the transformer.

International Classification:

H01H009/30

US Classification:

218/001000

Abstract:

A high-voltage loadbreak switch operates submersed in a dielectric fluid and may be configured to switch one or more phases of power using one or more phase switches. Each phase switch may include first and second stationary contacts. The first stationary contact may be connected to a phase of a high-voltage power source. Each phase switch also may include a non-stationary contact. The non-stationary contact may be placed in a first position to electrically couple the first stationary contact to the second stationary contact, and in a second position to decouple the first stationary contact and the second stationary contact. The region of motion of the first non-stationary contact between the first position and the second position includes an arcing region. The high-voltage loadbreak switch uses a fluid circulation mechanism to improve circulation of the dielectric fluid through the arcing region. To suppress arcing between different phases, a non-conductive baffle may separate different phase switches when more than one phase switch is used. A non-conductive baffle also may separate a phase from ground to prevent phase-to-ground arcing.
