Below, embodiments of the invention are described with reference to the accompanying drawings.
Figure 12 is that the circuit diagram of the electric power of one embodiment of the present of invention with the configuration example of the electric substation of switching device usefulness switching device shifter adopted in expression.
Article two, main bus bar 1,2 is provided with the main bus bar circuit breaker 3,4 that an end separately is connected with main bus bar, and these main bus bars are connected with an end of disconnect 5 with the other end of circuit breaker 3,4, and the other end of this disconnect 5 is connected with load.If adopt electric substation's structure of this two main bus bar modes, then switchable two main bus bars exist in abutting connection with ground with circuit breaker 3,4, when even one main bus bar 1 stops because of maintenance or fault etc., can main bus bar be disconnected with circuit breaker 3 by handover operation and make another main bus bar circuit breaker 4 closures, then can use 2 pairs of predetermined load power supplies of another main bus bar, thereby can improve the reliability of power supply.
Fig. 1 and Fig. 2 be the electric power of expression one embodiment of the present of invention with front view and the partial, partially-cross-sectioned side-elevation view of switching device with the pith of switching device shifter, the main bus bar of expression and Figure 12 is with circuit breaker 3 corresponding parts.
Main bus bar comprises with the structure of circuit breaker 3: paired fixed component 6 and movable part 7, the current-collector or other guiding parts 7a that this movable part 7 are led in the mode of axially carrying out switch motion along this movable part 7, the not shown drive unit that this movable part 7 is carried out switching manipulation, and the portion of mechanism that the switching manipulation power of this drive unit is passed to movable part 7.This portion of mechanism has: driven device drives the rotating driveshaft 8 of rotation, a pair of its approximate centre position is connected to the discoideus eccentric load balancer 9a on this rotating driveshaft 8,9b, at these eccentric load balancers 9a, form the cam path 10a of the ring plain track of identical shaped sealing on the relative part of 9b respectively, 10b, can be on one side at these cam paths 10a, rotate among the 10b, mobile on one side rotatable parts 11a such as roller, 11b, and one end and these rotatable parts 11a, the common axis 11 of 11b connects, and the connecting rod 12 that the other end is connected with movable part 7.
The shape of the cam path 10a of eccentric load balancer 9a forms the ring plain track and as shown in Figure 1 of sealing as a whole, and the peripheral part fourth class of discoideus eccentric load balancer 9a is divided into following four angular range 13a～13d: the first angular range 13a from the centre axis of rotating driveshaft 8 in the circular-arc part of the less r1 of radius and stipulated that movable part 7 is in the extreme position of pass; The second angular range 13b is positioned at the position relative with the first angular range 13a, is formed on the circular-arc part of the bigger r2 of radius and has stipulated the extreme position that movable part 7 is in out from the centre axis of rotating driveshaft 8; Third angle degree scope 13c and the 4th angular range 13d are respectively the coupling part of the roughly straight line that is connected this first angular range 13a and the second angular range 13b sleekly.
Illustrate indicatedly as described later, minor radius r1 is according to the corresponding decision of the open position of movable part 7, and long radius r2 is according to the corresponding decision of make position of movable part 7.On the other hand, the shape of the cam path 10b of eccentric load balancer 9b with the relative position of eccentric load 9a on form the ring plain track of a sealing of identical shape.Herein, owing to use a pair of eccentric load balancer 9a, 9b, thereby, when eccentric load balancer 9a, 9b are the center rotation with driving shaft 8, rotation member 11a, 11b then rotate while moving up and down along formed cam path 10a, 10b on part at a pair of eccentric load 9a, 9b, can under the situation of not throwing off with cam path 10a, 10b actuating force be passed to movable part 7 reliably.But, in other embodiments, also can only use an eccentric load balancer 9a to be implemented under the situation that rotatable parts 11a do not throw off with cam path 10a actuating force is passed to movable part 7 reliably.
At this moment, when being made the rotation of rotating driveshaft 8 clockwise directions by not shown drive unit, the eccentric load balancer 9a, the 9b that become one with this rotating driveshaft 8 also rotate in the same way.Utilize the rotation of this eccentric load balancer 9a, 9b, then rotatable parts 11a, the 11b that can rotate in cam path 10a, 10b as shown in Figure 3, in roughly straight line portion scope, relatively rotate from angular range 13a to angular range 13b, soon, then in cam path 10a, the 10b of angular range 13c shown in Figure 4, relatively rotate.When rotatable parts 11a, 11b in cam path 10a, the 10b of the angular range 13b of angular range 13a before angular range 13c when mobile, change to r2 from r1 to rotatable parts 11a, the cam path 10a of 11b present position part, the distance of 10b from the central axis of rotating driveshaft 8, and by connecting rod 12 movable part 7 is driven upward and to become and fixed component 6 state of contact.Like this, main bus bar has been finished from the switching of off-state to closure state with 3 of circuit breakers.
And then, when making rotating driveshaft 8 when clockwise direction rotates by not shown drive unit, as shown in Figure 5, rotatable parts 11a, the 11b that can rotate in cam path 10a, 10b because of the rotation of eccentric load balancer 9a, the 9b then roughly straight line portion from the circular-arc part of angular range 13c to angular range 13d relatively rotates, soon, then in cam path 10a, the 10b of angular range 13a shown in Figure 1, rotate.Rotatable parts 11a, 11b are when relatively moving in cam path 10a, the 10b of the angular range 13d of angular range 13c before angular range 13a, change to r1 from r2 to rotatable parts 11a, the cam path 10a of 11b present position part, the distance of 10b from the central axis of driving shaft 8, and movable part 7 is driven the state that becomes with the fixed component disconnection downwards by connecting rod 12.Like this, 3 of main bus bar circuit breakers are finished from the switching of closure state to off-state.
As mentioned above, when rotating driveshaft 8 being rotated in the clockwise direction by not shown drive unit, its structure makes and is roughly discoideus eccentric load balancer 9a, 9b rotation, because rotation along with this eccentric load balancer 9a, 9b, by rotatable parts 11a, the 11b switching manipulation movable part 7 that can in cam path 10a, 10b, rotate, thereby, can alleviate the eccentric load that is applied on the rotating driveshaft 8 greatly.This be because, although in order to carry out the switch motion of movable part 7, as long as have cam path 10a, 10b basically, but as eccentric load balancer 9a, 9b, its structure is for also comprising the roughly discoideus of the part that do not have cam path 10a, 10b, thereby makes central axis and its core basically identical of rotating driveshaft 8.Because this discoideus eccentric load balancer 9a, 9b has alleviated the eccentric load that is applied on the rotating driveshaft 8 significantly, thereby can simplify the structure of not shown drive unit and rotating driveshaft 8.In addition, because cam path 10a, 10b and also can alleviate eccentric load along the use of rotatable parts 11a, the 11b of its rotation.
In addition, above-mentioned electric power is used in the switching device shifter with switching device, because cam path 10a, the 10b that will be formed on discoideus eccentric load balancer 9a, the 9b make the ring plain track of the sealing with angular range 13a～13d, thereby, compare the offset of the load that can also reduce eccentric load balancer 9a, 9b with the situation of the various structures of not using cam path 10a, 10b, thereby can alleviate the eccentric load that is applied on rotating driveshaft 8 and the drive unit, and simplify the structure of rotating driveshaft 8 and drive unit and the miniaturization of implementation structure.
This eccentric load alleviate simplification with the structure of drive unit and rotating driveshaft 8, also can realize with switching device shifter with switching device with circuit breaker 3 and the electric power that utilizes the drive unit of aforesaid special use to carry out switching manipulation by only adopting single main bus bar.In addition, as mentioned above, in the circuit structure of transformer station shown in Figure 12, because its structure is: disconnect with circuit breaker 3 in order to overhaul that a main bus bar 1 carries out handover operation and with main bus bar and to stop using and make another main bus bar usefulness circuit breaker 4 closures, the power supply that utilizes another main bus bar 2 to carry out to predetermined load; Thereby its structure also can be made and utilize shared drive unit to carry out the switching manipulation of these main bus bars with circuit breaker 3,4.But, in this case, for another main bus bar as described later with circuit breaker 4, require to have with main bus bar with the different operating characteristics of circuit breaker 3.
Fig. 6 is the performance plot of expression main bus bar with the stroke curve of the movable part of circuit breaker 3,4.
Stroke curve 14a shown in the top of Fig. 6 represents the action of above-mentioned main bus bar with the movable part 7 of circuit breaker 3, as shown in Figure 1, when rotatable parts 11a, 11b are positioned at the angular range 13a of cam path 10a, 10b, though promptly movable part 7 is in open position before the stop position b of stop position a behind eccentric load balancer 9a, 9b half-twist, but as shown in Figure 3, when mobile, movable part 7 moves to the make position of stop position c from the open position of stop position b in the angular range 13b of cam path 10a, 10b for rotatable parts 11a, 11b.Subsequently, as shown in Figure 4, when rotatable parts 11a, 11b were positioned at the angular range 13c of cam path 10a, 10b, movable part 7 all remained closed the position from stop position c to stop position d.As shown in Figure 5, when rotatable parts 11a, 11b were positioned at the angular range 13d of cam path 10a, 10b, 7 make positions from stop position d of movable part moved to the open position of stop position a.
In addition, the stroke curve 14b shown in the bottom of Fig. 6 represents the operating characteristics of main bus bar with the movable part of circuit breaker 4, represents eccentric load 9a, the 9b phase change situation with 90 ° of angles on direction of rotation.That is, when main bus bar was in off-state shown in Figure 1 with the movable part 7 of circuit breaker 3, main bus bar was in state shown in Figure 5 with the movable part of circuit breaker 4; And main bus bar is when being in state shown in Figure 3 with the movable part 7 of circuit breaker 3, and main bus bar is in the closure state of Fig. 4 with the movable part of circuit breaker 4; And then when main bus bar was in the closure state of Fig. 4 with the movable part 7 of circuit breaker 3, main bus bar then was in state shown in Figure 5 with the movable part of circuit breaker 4.
Below, the electric power of another embodiment of the present invention with the switching device switching device shifter, is herein and utilizes shared drive unit can satisfy above-mentioned main bus bar simultaneously to describe with switching device shifter with switching device with the electric power of the operating characteristics of circuit breaker 3,4.
Fig. 7 is the stereogram of expression main bus bar with the pith of circuit breaker 3,4, axially on the position of interval predetermined distance, constituting the portion of mechanism 15 that is the center with above-mentioned eccentric load balancer 9a, 9b and having portion of mechanism 16 at shared rotating driveshaft 8 with spline structure, and utilize the movable part 7 of portion of mechanism 15 switching manipulation main bus bars with circuit breaker 3, and utilize the movable part 17 of portion of mechanism 16 switching manipulation main bus bars with circuit breaker 4.The structure of main bus bar usefulness circuit breaker 3,4 at this moment as shown in Figure 8, the upper left side that has held the closed container 18 of portion of mechanism 15,16 is connecting and is holding the circuit breaker closed container 19 of main bus bar with circuit breaker 3, is then connecting in the upper right side of closed container 18 to have held the circuit breaker closed container 20 of main bus bar with circuit breaker 4.At this moment, two main bus bars are identical with the structure of circuit breaker 3,4 basically as mentioned above, though it is also identical to utilize shared drive unit 21 to drive the direction of rotation of eccentric load balancer of two portions of mechanism 15,16 of rotation, and its setting angle difference.That is, if axially be benchmark with the action of separately movable part 7,17, then main bus bar is in direction of rotation on leading 90 ° state with respect to main bus bar with circuit breaker 3 its eccentric load balancers with circuit breaker 4.
To be main bus bar be in the stop position b of Fig. 6 with the movable part 7 of circuit breaker 3 to the state of Fig. 7, and main bus bar is in the stop position f of Fig. 6 with the movable part 17 of circuit breaker 4.When making the clockwise direction half-twist of shared rotating driveshaft 8 from this state along the direction of arrow by shared drive unit 21, when stop position b moved to stop position c and be in closure state, main bus bar moved to stop position g and is kept closed from stop position f because of the rotation of eccentric load balancer with 17 of the movable parts of circuit breaker 4 main bus bar with the rotation of the eccentric load balancer of circuit breaker 3, movable part 7.Subsequently, when making shared rotating driveshaft 8 clockwise direction half-twists by shared drive unit 21, main bus bar rotates with the eccentric load balancer of circuit breaker 3, make movable part 7 when stop position c moves to stop position d and be kept closed, main bus bar moves to stop position h and becomes off-state from stop position g along with the rotation of eccentric load with 17 of the movable parts of circuit breaker 4.
Have again, when utilizing shared drive unit 21 to make shared rotating driveshaft 8 clockwise direction half-twists, the eccentric load balancer rotation of main bus bar circuit breaker 3, movable part 7 moves stop position a and when being in off-state, main bus bar keeps off-state from stop position h to stop position e because of the rotation of eccentric load balancer with the movable part 17 of circuit breaker 4 from stop position d.Thereafter, when utilizing shared drive unit 21 to make shared rotating driveshaft 8 in the clockwise direction again during half-twist, then turn back to the beginning state of stroke curve shown in Figure 6, main bus bar rotates with the eccentric load balancer of circuit breaker 3, and movable part 7 is when keeping off-state from stop position a to stop position b, and main bus bar moves stop position f because of the rotation of eccentric load balancer from stop position e with 17 of the movable parts of circuit breaker 4 and is in closure state.
Therefore, in the circuit structure of Figure 12, initial condition is that main bus bar is in closure state with circuit breaker 4 and main bus bar is in off-state with circuit breaker 3, from main bus bar during to electric, the anglec of rotation that shared drive unit and shared rotating driveshaft 8 are in Fig. 6 is 90 ° a state by disconnect 5.At this moment, main bus bar is in the make position of stop position f with the movable part of circuit breaker 4, and main bus bar is in the open position of stop position b with the movable part 7 of circuit breaker 3.Afterwards, for making main bus bar, the maintenance of carrying out main bus bar 2 is in off-state with circuit breaker 4, and make main bus bar be in closure state with circuit breaker 3, then make shared rotating driveshaft 8 rotation, reach 270 ° state behind the position via 180 ° of the anglecs of rotation of Fig. 6 by operating shared drive unit 21.So main bus bar is in the open position of stop position h with the movable part of circuit breaker 4, thereby and main bus bar is finished change action with the make position that the movable part 7 of circuit breaker 3 is in stop position d.
If the electric power that adopts this structure is with the switching device switching device shifter, owing to can obtain the mechanism portion 15,16 of main bus bar with same structure with circuit breaker 3,4, as long as change the phase place of both direction of rotation in its installment state, thereby the time simple in structure, even on the peripheral part of shared rotating driveshaft 8, at random set the direction of action of main bus bar, also can satisfy operating characteristics separately with the movable part of circuit breaker 3,4; Perhaps can stagger and constitute main bus bar in the axial optional position of shared rotating driveshaft 8 with circuit breaker 3,4.In addition, as long as although have cam path 10a, 10b basically for the switch motion of carrying out movable part 7, but roughly discoideus owing to comprising the part formation that does not have cam path 10a, 10b, thereby can alleviate the eccentric load that is applied to by on the shared rotating driveshaft 8 of shared drive unit 21 driving rotations as eccentric load balancer 9a, 9b.In addition, because 2 movable parts the 7, the 17th, the structure that has mechanically linked, thereby can carry out the mechanical type interlocking to mutual switching manipulation.
Fig. 9 and Figure 10 are the electric power of expression another embodiment of the present invention is used the pith of switching device shifter with switching device front view and end views.
In the embodiment shown in fig. 1, rotatable parts 11a, 11b is in the off-state of the center that is positioned at the most close shared rotating driveshaft 8, connect rotatable parts 11a, the link of the movable part 7 of the connecting rod between 11b and the movable part 7, be positioned at discoideus eccentric load balancer 9a though make, the axial length of the peripheral part of 9b is longer, but in the present embodiment, connect rotatable parts 11a, the axial length of the connecting rod 12 between 11b and the movable part 7 can shorten within the bounds of possibility, as shown in figure 10, a pair of eccentric load balancer 9a, 9b is configured to have the slightly bigger relative distance that movable part 7 can be drawn in wherein between it is in the face of part.
If the electric power that adopts this structure is with the switching device switching device shifter, same with the situation of previous embodiment, as eccentric load balancer 9a, 9b, make discoideusly by comprising the part that does not have cam path 10a, 10b, then can alleviate the eccentric load that is applied on the shared rotating driveshaft 8.But, though will be from rotatable parts 11a, 11b to movable part 7 make and be offset to the structural member of main bus bar with the configuration direction of circuit breaker 3, and with it as the eccentric load that is applied on the shared rotating driveshaft 8, but because by comparing with the situation of previous embodiment, the axial length that alleviates the weight of connecting rod 12 and shorten connecting rod 12 within the bounds of possibility can make the more close rotating driveshaft 8 of center of gravity of movable part 7, thereby can further alleviate the eccentric load that is applied on the shared rotating driveshaft 8.In addition, adopt this structure, can also on the direction of action of movable part 7,17, reduce the size of main bus bar with circuit breaker 3,4.
