Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
According to the drawings from fig. 1 to fig. 4, the measurement and control device of the generator excitation system comprises a measurement and control cabinet 1, and the measurement and control cabinet 1 is provided with a detachable measurement module 2 and a control display module. The wire fixing mechanism is arranged on the side wall inside the measurement and control cabinet 1 and is provided with a sliding chute 4, a sliding rod 5 is arranged on the sliding chute 4, a sliding block 6 is arranged on the sliding rod 5, a connecting block 7 is arranged on the sliding block 6, a protruding block 18 is arranged inside the connecting block 7, a wire fixing clamping block 19 is arranged on the protruding block 18, rotating shafts 12 are arranged at the top and the bottom inside the connecting block 7, gears 10 are arranged on the rotating shafts 12 and are connected through connecting rods 11, and blocking nets 8 are sleeved on the connecting rods 11. The side of the sliding rod 5 opposite to the connecting block 7 is of a rack type, and the gear 10 is meshed with the rack of the sliding block 6. The inner of the chute 4 is provided with a fixed limit block 9, and the fixed limit block 9 is connected with the connecting block 7 through a blocking net 8.
