Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of hydroelectric generating set automation jiggering and measures adjustment System, as shown in Figure 1, comprise be arranged on Hydropower Unit on lead 9, under lead 10 and water lead current vortex sensor 1 on 11, current vortex sensor 1 is connected with signal conditioning circuit 2, multi-way switch 3, amplifier 4, sample/retainer 5, A/D converter 6, computing machine 7 and controller 8 successively, controller 8 also respectively with multi-way switch 3, amplifier 4, sample/retainer 5 and A/D converter 6 be connected.
As Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5 and Fig. 6, on lead 9, under lead 10 and water lead 11 and be arranged on successively from top to bottom on axle 12, current vortex sensor 1 arranges 7, on lead 9 place's horizontal directions and with horizontal direction vertical direction, 1 current vortex sensor 1 be respectively installed, on lead 9 places current vortex sensor 1 be positioned at same plane, under lead 10 and water lead 11 with above lead the 9 corresponding positions being provided with current vortex sensor 1 current vortex sensor 1 be all installed, on lead 9 tops axle 12 on 8 key phase blocks 13 are evenly installed, 8 key phase blocks 13 are positioned at same plane, on lead 9 top in the position that the current vortex sensor 1 with horizontal direction is corresponding, 1 current vortex sensor 1 is installed, wherein 1 key phase block 13 is relative with current vortex sensor 1 position of above leading 9 tops.
The principle of work that adjustment System measured by a kind of hydroelectric generating set automation jiggering of the utility model is: measure the distance of current vortex sensor 1 to axle 12 by 7 current vortex sensors 1, the signal that current vortex sensor 1 exports is converted to standard voltage signal through signal conditioning circuit 2, standard voltage signal becomes digital signal successively after the amplification of multi-way switch 3, amplifier 4, sampling/retainer 5 and A/D converter 6 settling signal, sampling and analog to digital conversion, finally digital signal is sent into computing machine 7 and carry out computing, computing machine 7 provides unit axis Adjusted Option.Controller 8 controls the switching of multi-way switch 3 and opening/stopping of A/D converter 6.On lead 9, under lead 10 and the water current vortex sensor 1 of leading on 11 gather throw value, when axle 12 rotates current vortex sensor 1 position relative with key phase block 13, change due to measuring distance can cause the change of output voltage, the location point of 8 key phase blocks 13 of axle 12 is marked with this, in computing machine 7, lead 9 by engraving during 8 key phase block 13 location points, under lead 10 and the water throw data of leading 11 take out computational analysis, thus provide unit axis Adjusted Option.
