FIELD: wind power engineering. ^ SUBSTANCE: proposed wind electric generator contains frame, blade wheel installed of frame for rotation, electric generators set into rotation by bladed wheel, and control unit which selects definite supply wires running from generators for connection or disconnection of wires. Bladed wheel rests on shaft installed vertically to which driving gear wheel is connected. Frame is provided with rotating driven gear wheels in meshing with driving gear wheel, and shafts of driven gear wheels are connected with electric generators. Control unit contains rotation pickup designed to determine velocity of wind or speed of bladed wheel and it disconnects supply wires at rise of speed, thus decreasing number of operating electric generators. Method of construction of wind electric generator from several stages comes to mounting first stage members on foundation, mounting of self-lifting crane, lifting of self-lifting crane using first stage member as support, lifting of self-lifting crane with use of second stage member as support, and so on. Self-lifting crane contains mounting clamps made for fastening and unfastening of members of each stage. ^ EFFECT: enlarged operating capabilities. ^ 1 cl, 20 dwg |
