Patent number: 8153916Abstract: 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 housings 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.Type: GrantFiled: August 14, 2008Date of Patent: April 10, 2012Assignee: Cooper Technologies CompanyInventors: Kurt Lawrence Lindsey, Randal Vernon Malliet, Rick Alan Rachwal, Patrick Harold Pride

Patent number: 6825426Abstract: 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.Type: GrantFiled: April 4, 2003Date of Patent: November 30, 2004Assignee: McGraw-Edison CompanyInventors: Frank John Muench, Patrick Harold Pride

Patent number: 6797909Abstract: 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.Type: GrantFiled: February 27, 2003Date of Patent: September 28, 2004Assignee: McGraw-Edison CompanyInventors: Patrick Harold Pride, Joseph Peter Gerovac, Paul Steven Kozicki, Allen Leroy Johnson
