GAPPING MEASUREMENT SENSOR FOR HV CONNECTOR

摘要

A cable is described for connecting to a connector (1) of a high-voltage device. The cable comprises an integral yield sensor. The yield sensor may be a pressure or force sensor, or a displacement sensor, comprising a stator part (22) and a mobile part (20), and a spring (14) for maintaining a compression force on the end portion (15) of the cable towards the connector (1) of the high-voltage device. According to an embodiment of the invention the displacement sensor comprises a Hall effect sensor (21) and a linear array of magnetic elements (20), arranged such that the Hall effect sensor (21) moves relative to the linear array if there is any movement between the stator (22) and mobile (20) parts of the sensor. The magnetic field readings are interpreted in order to determine the amount of movement, and can be transmitted wirelessly to a remote monitoring station. A system is also described for controlling the high voltage device in response to pressure and other information received from sensors in the cable.
