Abstract: The high voltage relay consists of a main body (1). One set of electrical contacts (2a, 2b) upper and lower respectively. High voltage connections to connect the voltage being switched (3a, 3b) are electrically connected to the upper and lower contacts respectively. Several size options for the electrical contacts will allow for a wide range of currents. A cylinder (4) driven by a fluid (e.g. Air, Nitrogen, Hydraulic fluid) moves the electrical contacts together during the ON state of the device. During the OFF state of the device the cylinder moves the electrical contacts apart to isolate the switch voltage. The greater the High Voltage being switched the greater the distance the electrical contacts must be moved apart in the OFF state. The cylinder is supplied the fluid power from a small solenoid (5) on the device. This solenoid has control voltage connections to actuate the device.

Abstract: An electrical switch includes a tubular housing having a conductor receiving end and an operating end opposite the conductor receiving end. The tubular housing also includes a conductive interface positioned intermediate the conductor receiving end and the operating end. An operating rod extends through the operating end toward the conductor receiving end. The operating rod is moveable between a first position to engage the electrical switch and a second position to disengage the electrical switch. A gelatinous dielectric material is provided within a portion of the tubular housing, and around the operating rod, in the operating end to prevent voltage from the conductive interface from arcing to the operating end. The gelatinous dielectric material is configured to deform to maintain contact with the operating rod in the first position and the second position.

Abstract: The disclosure relates to a contact drive arrangement for the movement of at least one contact in high-voltage switchgear systems having a contact drive and having an auxiliary switch, which has at least two auxiliary contacts. The contact drive works together with the at least one contact and with a first auxiliary contact. Furthermore, a delay drive is connected functionally in parallel with the contact drive, and the delay drive works together with a second auxiliary contact. The first and second auxiliary contact are electrically connected in series. In addition, the delay drive has a damping element, and by means of the damping element the time for a switching operation is extended in comparison with the time for a switching operation with the contact drive.
