Patent documentation 1: JP 2000-312411 publication
These 3 performances be listed as required by L-type gas insulated bus of current electrifying performance, withstand voltage properties and short time resistance to current electrifying performance.Wherein, Figure 13 is used to be described the electromagnetic force produced by the most serious short time electrical current i of mechanical stress.On L shape conductor, 5 electromagnetic forces produced as shown in figure 13, represented by distributed load Fs and distribution loading FL.The size of electromagnetic force square to increase for ratio with the size of short time electrical current i.Short time resistance to current electrifying performance refers to when the short circuit currents such as ground fault flow into conductor, do not occur because of bad etc. the performance of the melting loss of contact, the distortion of conductor and the breakage caused, withstand voltage properties, although tolerance time is shorter 2 ~ 3 seconds, produce the electromagnetic force on direction shown in Figure 13.
The power using the L shape gas insulated bus of schematic diagram to the existing structure shown in Fig. 9 of Figure 12 to be subject to by electromagnetic force is described.Electromagnetic force is distributed load, if but in order to make explanation simplify and as equal distribution load make a concerted effort represent, making a concerted effort of the electromagnetic force then produced relative to distance L1 by distance L2 and distance L3 is F1, making a concerted effort of the electromagnetic force produced relative to distance L2 by distance L1 is F2, making a concerted effort for F3 of the electromagnetic force produced relative to L3 by L1.These make a concerted effort to produce all unidirectional moment rotated around A point.If consider the moment of A point, then respectively with joint efforts F1, F2, F3 and the substantially central portion of distance L1, L2, L3 produce roughly equal.
At this, carry out slightly detailed description again by the moment that Fig. 9, Figure 12 and formula opposing connection A point rotate.Contact site 9 has flexible contact to connect, and therefore only transmits the power of conductor axle right angle orientation, not carry-over moment.Thus, can think that the C point of Figure 12 is free end.Too, therefore the D point of Figure 12 also becomes free end to contact site 11.L shape conductor 5 and electrode 3

Each moment is:
M
1＝L1/2×F1
M
2＝L2/2×F2
M

The two ends of L3 are fixed at contact site 9 and 11, therefore suppose the power being subject to F3 half at L2 side.Thus, the full moment Mt rotated around A point is expressed as:
Mt＝M
1+M
2+M
3＝(L1×F1+L2×(F2+F3))/2
Below, reference Figure 14 is to the set bolt 6 produced by the moment Mt rotated around A point

1the full drawing load Fb of upper generation is following formula:
Fb＝(L1×F1+L2×(F2+F3))/2r+(F2+F3/2)
As mentioned above, at set bolt 6

Below represent the value that Fig. 2 illustrated dimension is substituted into:
L1＝500[mm]
L4＝2500[mm]
r＝40[mm]
The short-time current flowing into L shape gas insulated bus is set to: i=104kAp (40kA × 2.6 times).
The result calculated by above value is as follows:
F1＝352[kgf]
F4＝336[kgf]
M

Fb＝F4/2+M
1/r＝2368[kgf]＝23.2[kN]
In present embodiment 1, owing to eliminating M

And, at the insulating cell 2 of tank 1 with bonding conductor 10 side
1between the bellows (bellow) 12 of Large travel range for absorbing inner conductor, tank is installed.
The structure of present embodiment 2 as above, therefore except having the set bolt 6 that can make radial conductor 5A of execution mode 1
1the minimum effect of the diameter of bolt, bolt pitch dimension outside, by increasing the degree of freedom of the inclination of length direction conductor 7, the displacement absorbability of bellows 12 can not be hindered, suppress to produce because of electromagnetic force, radial conductor 5A around set bolt 6
1the moment produced.Consequently: conductor diameter, bolt pitch dimension can be reduced, the function having and absorb Large travel range can be reached and make the object of Whole Equipment downsizing.
[execution mode 3]
Below, be described with reference to the execution mode 3 of Fig. 5 and Fig. 6 to gas insulated bus involved in the present invention.Fig. 5 represents the state enclosing radial conductor 5A in tank 1, and Fig. 6 is the profile of the assembling process representing Fig. 5, represents and is loading the radial conductor 5A and insulating cell 2 that are integrated
2state before.
In Fig. 5 and Fig. 6, present embodiment 3 is to change the syndeton of length direction conductor 7 in aforesaid execution mode 1 and radial conductor 5A for feature, and the structure identical with execution mode 1 pays identical symbol, and the repetitive description thereof will be omitted.
Present embodiment 3 with centre line C L

2, electromagnetic force because acting on length direction conductor 7 can be made and the bolt drawing load produced on radial conductor 5A is 0kg.That is, radial conductor 5A only needs to bear the moment M from being produced by F1
1the drawing load be subject to.That is, in fig. 2,
Mt＝M
1＝Fb×r
Around set bolt 6
1the moment produced diminishes.
According to said structure, if calculate set bolt 6 by the value of execution mode 1
1drawing load Fb, then:
Fb＝M
1/r＝88000/40＝2200[kgf]＝21.6[kN]
93% can be reduced to further compared with execution mode 1, relative to existing structure, can 63% be reduced to.
When using the structure of present embodiment 3, play effect in the longer situation of L4, short time resistance to electric current is larger.
As mentioned above, according to the present embodiment 3, the drawing load making set bolt can be provided to be L shape gas insulated bus that is minimum, that suppress the electromagnetic force influence produced because of short-time current.
[variation of execution mode 3]
Length direction conductor 7 is not limited to aforesaid Fig. 5, Fig. 6 with the connection of radial conductor 5A, can also be out of shape as Fig. 7.
What Fig. 7 represented is the example being also applicable to following gas insulated bus: the length direction conductor 7 being positioned at contact site 9 side is extended to tank peristome 1b side, and arranges the insulating cell 2 being fastened on and replacing inaccessible lid 4 to arrange
3embedded electrode 3
3on bonding conductor 10A, via contact chip 8
3the pole shape contact 7 of connecting length direction conductor 7
1with this bonding conductor 10A, there is roughly orthogonal T-shaped conductor structure thus.
And although not shown, but the T-shaped conductor structure of Fig. 7 also can change to criss-cross conductor structure.
[execution mode 4]
Gas insulated bus in the variation (Fig. 7) of execution mode 1 (Fig. 1) described above and even execution mode 3 is the example being applicable to the phase structure receiving a bus in a tank, but the so-called three-phase that present embodiment 4 is applicable to the bus receiving three-phase in a tank sums up structure.Below, be specifically described with reference to Fig. 8.
Fig. 8 represents that the three-phase of present embodiment 4 sums up the figure of the assembling process of the gas insulated bus of structure.It should be noted that, in Fig. 8, eliminate the length direction conductor 7 in tank 1 and contact site 9.
Below, the L shape conductor of the existing shape of contrast shown in Figure 10, is described the assembling sequence of the gas insulated bus of present embodiment 4.
By consolidation radial conductor 5A and insulating cell 2
2conductor assembled part when being installed to tank 1, need to be assembled by tank peristome 1c.In the L shape conductor 5 of the existing shape shown in Figure 10, during X partial insertion tank peristome 1c by L shape conductor 5, in order to not make its damaged, it is sometimes made to turn clockwise, the high and assembling operation also spended time of assembling difficulty.
But as shown in Figure 8, the radial conductor 5A of the gas insulated bus of present embodiment 4 is straight line, so there is no the X part being bent approximately in 90 degree in Figure 10, assembling becomes easy, can shorten the activity duration of assembling.And in the L shape conductor 5 of existing shape, as shown in figure 11, can not carry out visual confirmation at contact site 9 from tank peristome 1c, therefore final joint (docking) only can carry out the contact site 11 of visual confirmation from tank peristome 1a side.
To this, in present embodiment 4, identical with Fig. 6 of aforesaid execution mode 3, contact site 9 is arranged at the intersection point of radial conductor 5A and length direction conductor 7, therefore the visual confirmation of contact site 9 also can be carried out from tank peristome 1c, final joint can be both contact site 9 and contact site 11, thus can improve packaging efficiency.
By above structure, while can shortening the assembling operation time, also can make conductor shape miniaturization, thus cheap gas insulated bus can be provided.
[variation of execution mode 5]
This structure also can be applicable to have the gas insulated bus as the roughly orthogonal T-shaped conductor structure in Fig. 7.And, also can be applied to criss-cross conductor structure.
According to execution mode described above, for radial conductor, the drawing load of bolt that produces because of electromagnetic force diminishes, and the conductor diameter of radial conductor consequently can be made to minimize.
