Unless you count barrage balloons, I don't think there's a historical example yet. However, this is probably a valuable tactic, not so much because it would bring down lots of helicopters as because it would make the helicopter pilots more cautious and hence less effective. There is considerable work being done on equipping helicopters with some sort of short-range radar or lidar that can "see" wires, and a good many existing military helicopters are equipped with gadgets designed to cut any wires they strike, but the problem is by no means solved yet.
