Fan yaw brake with friction plate abrasion monitoring function and monitoring system thereof

The utility model relates to a fan yaw brake with a friction plate abrasion monitoring function and a monitoring system of the fan yaw brake. The yaw calipers comprise insulation friction plates, the insulation friction plates abut against the yaw gear ring, and a plurality of sets of double-end wires are embedded in the insulation friction plates in the thickness direction; the power supply is respectively connected with each group of double-end leads to form a closed loop; and the current sensing switch is sleeved on the double-end lead. Compared with the prior art, a plurality of groups of double-end wires are embedded in the thickness direction of the friction plate, the power supply is used for keeping current flowing in the wires, and the current sensing switch is used for monitoring the current, so that when the wire at one end of the friction plate at a certain thickness is worn off, the wire is broken; the current sensing switch can detect that the current is reduced or returned to zero, so that the
