Latest Patents

Cochran's latest patents include a transformer bushing and a high voltage electrical switch. The transformer bushing is designed for use with tank-type electrical transformers. It utilizes a maximum amount of conductor material to achieve the necessary shape and physical strength while minimizing the insulating material to fulfill its insulating function. This bushing can be secured to the transformer tank wall using an externally mating clamp assembly or internally threaded securing members.

The high voltage electrical switch is engineered to interrupt high voltage electrical currents by directing an extended curvilinear arc plasma path within a fluid insulating medium. Its preferred embodiment is designed to store rotational energy in a motor spring, release that energy, and latch an opposite motor spring all in one movement of the operator's handle. Additionally, the switch features a mechanical overdrive unit that allows the operator's handle to rotate only a fraction of the total rotation traveled by the movable contact. An anti-stick or weld break feature is also included to manually initiate the rotation of the movable contact in case of adhesion between the contacts. Furthermore, a novel contact design aids in controlling the arc plasma path and ensures multiple contact paths for reliable connections.
