nullThe outside operation handle accessed pulls driving shaft 4.4 clockwise，Rotate around driving shaft 4.4 together with the first connecting plate 4.7 being fixed together with driving shaft 4.4，Owing to the horizontal component of the first connecting plate 4.7 and the bottom of the first cam 4.8 connect，And the first cam 4.8 is integrally fixed on driven shaft 4.5，So driven shaft 4.5 rotates together，Together with being integrally fixed at driven shaft 4.5 due to the second cam 4.13 on driven shaft 4.5 and the 3rd cam 4.14，So the second cam 4.13 on driven shaft 4.5 rotates together with the 3rd cam 4.14 and driven shaft 4.5，Owing to on-load switch 3 and operating mechanism 4 are connected by being arranged on the adapter sleeve 4.5.1 and the adpting flange 3.1.1 being arranged on on-load switch 3 inner main axis 3.1 1 termination of driven shaft 4.5 1 termination in 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，It is achieved thereby that close a floodgate in the left side that operating mechanism 4 drives on-load switch 3、Separating brake closes a floodgate with 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；Owing to 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；Owing to 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, the stopping until the moving contact 3.13 moved in metal moving contact inner sleeve 3.5 and static contact 3.10 are fully contacted and put in place；Insulation moving contact outer sleeve 3.4 also swings accordingly with this simultaneously.Simultaneously, owing in operating mechanism 4, the arc-shaped part of a limiting plate 4.18 on right side promotes sliding shaft sleeve 4.12 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, the limiting plate 4.18 in synchronize with this is left side rotates clockwise together with the second cam 4.13 and the 3rd cam 4.14, 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 promoting the first microswitch 4.22, first microswitch 4.22 closes, close a floodgate on the left of on-load switch 3.The left side "on" position of on-load switch 3 is as shown in Figure 6.
Operating mechanism 4 manual operation drives the left side separating brake of on-load switch 3.
Counterclockwise pulling driving shaft 4.4, the main shaft 3.1 in driving shaft 4.4 rotational band dynamic load switch 3 rotates, and owing to 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；Owing to 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, until the moving contact 3.13 moved in metal moving contact inner sleeve 3.5 disconnects with static contact 3.10；Insulation moving contact outer sleeve 3.4 also swings accordingly with this.nullSimultaneously，The second cam 4.13 on driven shaft 4.5 rotates counterclockwise together with the 3rd cam 4.14 and driven shaft 4.5，The limiting plate 4.18 on right side is owing to being blocked by sliding shaft sleeve 4.12，Therefore the limiting plate 4.18 on right side is clockwise to the second cam 4.13 and the 3rd cam 4.14 and the stop of sliding shaft sleeve 4.12 distance away afterwards disengaging sliding shaft sleeve 4.12 around the rotating shaft between the second cam 4.13 and the 3rd cam 4.14 relative to the second cam 4.13 and the 3rd cam 4.14 and returns to original state under the effect of the first torque spring 4.20，The most whole second cam 4.13、3rd cam 4.14、Two limiting plates 4.18 are returned to normal state，Now the action reed of the first microswitch 4.22 flicks，On the left of on-load switch 3, separating brake completes.The left side gate-dividing state of on-load switch 3 is as shown in Figure 6.
The right side making process of on-load switch is identical with the operation of left side making process, therefore with reference to above-mentioned work process.The right side making process of on-load switch is similar to the left side making process of on-load switch, and difference is simply pulled driving shaft 4.4 and rotated counterclockwise, and not describes in detail herein.The right side separating brake process of on-load switch and the left side separating brake similar process of on-load switch, difference is simply pulled driving shaft 4.4 and is rotated clockwise, and not describes in detail herein.
Operating mechanism 4 electric operating drives the left side of on-load switch 3 to close a floodgate.
The process that operating mechanism 4 electric operating drives the left side of on-load switch 3 to close a floodgate drives the process of the left side separating brake of on-load switch 3 with operating mechanism 4 manual operation, difference is manipulation motor 4.6, driving shaft 4.4 is driven to rotate by gear drive, signal output part due to the first microswitch 4.22, the signal output part of the second microswitch 4.23 and the signal output part of the 3rd microswitch 4.24 are all connected with being connected with motor 4.6, when the first microswitch 4.22, when the second microswitch 4.23 and any one Guan Bi of the 3rd microswitch 4.24, motor all stops operating, the process that remaining action all drives the left side of on-load switch 3 to close a floodgate with operating mechanism 4 electric operating is identical, not describe in detail herein.
Part that the present invention does not relate to is the most same as the prior art or uses prior art to be realized.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
