HIGH VOLTAGE SWITCH BLADE CLOSING DETECTOR

摘要

A blade closing detector for an electric power switch includes a blade closing detector and an electronic or visual indicator. A first type of detector uses a gravity switch and a magnetic pickup to detect proper engagement between the blade and the switch. A second type of detector uses a sliding latch with a visual indicator rod to provide a visual indication of proper engagement of the blade within the jaws. A third type of detector uses a magnetic switch with a pivot arm and a dome shaped visual indicator. These detectors may be deployed individually or in combination and may be augmented with communication equipment to transmit switch status to a remote location. It will be understood that specific embodiments may include a variety of features in different combinations, as desired by different users.

主权项

1. A blade closing detector for a high voltage electric power switch that includes a pivoting blade arm and jaws for receiving the blade arm to form a high voltage electrical connection in which a proper electrical connection is created by proper physical engagement of the blade arm within the jaws, the blade closing detector comprising:
a first detector component having a first indicator actuation element carried by the blade arm; a second detector component having a second indicator actuation element located near the jaws; the first and second detector components positioned to cause the first indicator actuation element to become positioned adjacent to the second indicator actuation element when the blade arm is properly engaged within the jaws; wherein the first and second indicator actuation elements have an indication sensitivity causing an indicator actuation to be caused by the first and second indicator actuation elements when the blade arm comes into proper physical engagement within the jaws; and wherein the indication sensitivity causing no indicator actuation to be caused by the first and second indicator actuation elements when the blade arm comes into close proximity of the jaws without entering into proper physical engagement within the jaws.
