Title:
HIGH VOLTAGE OPERATING ROD SENSOR AND METHOD OF MAKING THE SAME
Document Type and Number:
WIPO Patent Application WO2004073004
Kind Code:
A3
Abstract:
Methods and system for making and using vacuum switching devices are disclosed. A vacuum switching device (105) has an operating rod (120) for actuating a movable electrical contact within the device. The operating rod (120) may be a hollow epoxy glass We (205) with an electrical sensor (210, 215) disposed within it, and there may be an elastomeric polymer filling compound (260) disposed within the tube (205) and encasing the sensor (210, 215). The operating rod (120) may be attached to the movable electrical contact on one end by a steel end-fitting (225, 230) that has been press-fit into the tube (205) and secured with at least one cross pin (235). In this way, a very secure electromechanical connection may be made between the operating rod (120) and the rest of the vacuum switching device (105), and the sensor (210, 215) is protected from shock associated with the operation of the device. Moreover, the vacuum switching device (105) is compact and easy to construct.
