Description
Technical field
The present invention relates to a kind ofly to be applied to delivery electricity equipment or power receiving equipment that electric power for example uses, have the switching device of insulating bar that is connected with movable conducting parts and the operating mechanism portion that drives this insulating bar.
Background technology
As existing switching device, a kind of switching device is arranged as shown in figure 17.Figure 17 is the side cross-sectional view of expression switching device.Among Figure 17, not shown drive source by operating mechanism portion 14 drives action bars 14b, the driving interlock of action bars 14b therewith, drive rod 16 rotates counterclockwise with the axle center of fulcrum 15 around this fulcrum 15, and the insulating bar 13 that is connected with the opposite side 16b of drive rod 16 is pressed towards the top.The movable energising axle that is connected with a side 13a as the upper end side of insulating bar 13 8 moves towards the top, and the fixed side electrode 5 of the movable lateral electrode 7 of movable energising axle 8 and fixing energising spools 6 contacts.By contacting of fixed side electrode 5 and movable lateral electrode 7, make vacuum interrupter (Japanese: vacuum バ Le Block) closed between 1 electrode.
In addition, when separating between the electrode of vacuum interrupter 1, not shown drive source by operating mechanism portion 14 drives action bars 14b and moves in the opposite direction towards the side of the action when closed with electrode, the driving interlock of action bars 14b therewith, drive rod 16 clockwise rotates with the axle center of fulcrum 15 around fulcrum 15, and the insulating bar 13 that is connected with the opposite side 16b of drive rod 16 is depressed towards the below.The movable energising axle that is connected with a side 13a as the upper end side of insulating bar 13 8 moves towards the below, and the movable lateral electrode 7 of movable energising axle 8 breaks away from from the fixed side electrode 5 of fixing energising axle 6, and contact condition is disengaged.Because fixed side electrode 5 is disengaged with the contact condition of movable lateral electrode 7, so is separated between the electrode of vacuum interrupter 1.
But, in the above-mentioned switching device, in order to guarantee that the short circuit that takes place in the accident for example and the various overvoltage of generation are had suitable nargin, because existing knowledge is that dielectric strength is provided with difference and preferential with ground connection, therefore wish with dielectric strength according between over the ground＜the out-phase main circuit between＜order between main circuit increases progressively setting.The method of the selected dielectric strength of nargin that this consideration is suitable is also referred to as insulation coordination.
Insulation characterisitic to above-mentioned switching device describes.The movable conducting parts of one side 13a of insulating bar 13 and the insulation creepage distance of 3 on metallic base station frame that for example is arranged in the earth potential side at Fig. 7 shown in E.As shown in figure 17, in order suitably to guarantee the creepage distance E that insulate, at the movable conducting parts of a side 13a of insulating bar 13 and for example be positioned on the insulating bar 13 of 3 on metallic base station frame of earth potential side a plurality of folded up portion 13c are set at interval.
When being short-circuited in the accident for example or producing overvoltage, make short circuit occur in the earth potential side, be base station frame 3 sides, rather than occur between main circuit or the out-phase main circuit between.In addition, when causing the insulation property variation, also must make short circuit occur in the earth potential side, be base station frame 3 sides because of stained or dewfall etc.By being suppressed to the damage of switching device less like this.
In the existing switching device of this kind structure,, therefore select the insulating bar 13 and the folded up portion 13c of the rated voltage of corresponding switching device to use owing to folded up portion 13c is set on insulating bar 13 suitably to guarantee the creepage distance E that insulate.
