Title:
DISCONNECTOR
Document Type and Number:
Japanese Patent JP2015076160
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To highly accurately detect a load on a drive source with a simple structure without interrupting the supply of electric power.SOLUTION: In a disconnector 1, a torque detection part 61 is provided in the middle of a driving rod 51 that transmits power from a drive device 45 to a rotating insulator device 22 and a blade 34, and whether or not an amount of a torque acting on the driving rod 51 has reached a prescribed set torque amount is detected. Specifically, the driving rod 51 is divided into an upper rod piece and a lower rod piece, a spring and a plurality of electrodes are provided between the upper rod piece and the lower rod piece, and a contact detection circuit for detecting contact between electrodes is provided. When the amount of the torque acting on the driving rod 51 reaches the set torque amount, the electrodes make contact with each other, and the contact detection circuit detects the contact and outputs a detection signal.
