The course of work of the present embodiment is:

Because the on-load switch 3 in the present embodiment is by operating mechanism 4 drive; Earthed switch 1 is driven separately by ground connection operating mechanism 2 simultaneously; Therefore the present embodiment is when the description course of work, just drives with operating mechanism 4 that on-load switch 3 closes a floodgate, separating brake is as a whole is described.In like manner, just drive with ground connection operating mechanism 2 that earthed switch 1 closes a floodgate, separating brake is as a whole is described.

Because the operating mechanism 4 in the present embodiment drives on-load switch 3 to realize left side making process and the right side making process of on-load switch 3, the left side making process of the on-load switch 3 in the present embodiment and the operation of right side making process are identical, therefore the present embodiment just drive on-load switch 3 for operating mechanism 4 on the left of making process be specifically described.

On the left of load switch in on-load switch in the present embodiment, "on" position as shown in Figure 7.

Operating mechanism 4 manual operation drives the left side of on-load switch 3 to close a floodgate.

The operating grip clockwise direction of outside access pulls driving shaft 4.4, rotate around driving shaft 4.4 together with the first connecting plate 4.7 that driving shaft 4.4 is fixed together, because the horizontal component of the first connecting plate 4.7 is connected with the bottom of the first cam 4.8, and the first cam 4.8 is fixed on driven shaft 4.5, so driven shaft 4.5 rotates together, because the second cam 4.13 on driven shaft 4.5 and the 3rd cam 4.14 are fixed together with driven shaft 4.5, so the second cam 4.13 on driven shaft 4.5 rotates together with driven shaft 4.5 with the 3rd cam 4.14, because on-load switch 3 is connected with the adpting flange 3.1.1 being arranged on on-load switch 3 inner main axis 3.1 1 termination by the adapter sleeve 4.5.1 being arranged on driven shaft 4.5 1 termination in operating mechanism 4 with operating mechanism 4, the main shaft 3.1 achieved in on-load switch 3 is connected with the driven shaft 4.5 in operating mechanism 4, thus achieve operating mechanism 4 and drive the left side of on-load switch 3 to close a floodgate, close a floodgate in separating brake and right side, separating brake, therefore, driven shaft 4.5 rotates, and drives the main shaft 3.1 in on-load switch 3 to rotate to the left, because shift fork 3.9 lower end is fixedly installed on main shaft 3.1, main shaft 3.1 rotates and drives shift fork 3.9 to rotate, because shift fork 3.9 is connected with insulation adapter sleeve 3.16 swing type, shift fork 3.9 rotates and pulls insulation adapter sleeve 3.16 to rotate, thus drive metal moving contact inner sleeve 3.5 to move, stop until the moving contact 3.13 moved in metal moving contact inner sleeve 3.5 fully contacts with fixed contact 3.10 and puts in place, the moving contact outer sleeve 3.4 that simultaneously insulate also swings accordingly with this.Simultaneously, to rotate around the second support column 4.11 and the limiting plate 4.18 on right side is swung down to the bottom of sliding shaft sleeve 4.12 because the arc-shaped part of a limiting plate 4.18 on right side in operating mechanism 4 promotes sliding shaft sleeve 4.12, synchronous is therewith that the limiting plate 4.18 in left side rotates clockwise together with the 3rd cam 4.14 with the second cam 4.13, second connecting plate 4.15 is connected with the second cam 4.13 and the 3rd cam 4.14, therefore the second connecting plate 4.15 also rotates clockwise, when the second connecting plate 4.15 turns to the action reed of promotion first sensitive switch 4.22, first sensitive switch 4.22 closes, close a floodgate on the left of on-load switch 3.On the left of load switch in on-load switch, "on" position as shown in Figure 7.

Operating mechanism 4 manual operation drives the left side separating brake of on-load switch 3.
