Electric current energising performance, withstand voltage properties and these 3 of performances of anti-electric current energising of short time are listed as the desired performance of L type gas insulated bus.Wherein, use Figure 13 that the electromagnetic force that produces through the most serious short time electrical current i of mechanical stress is described.The electromagnetic force of 5 generations is shown in figure 13 on L shaped conductor, is represented by distributed load Fs and distribution loading FL.The size of electromagnetic force square is that ratio increases with the size of short time electrical current i.Anti-electric current energising of short time performance is meant at short circuit currents such as ground faults and flows under the situation of conductor; Bad etc. the performance of breakage, withstand voltage properties that the distortion of melting loss, conductor because of contact causes does not take place; Though tolerance time is short 2～3 seconds, is created in the electromagnetic force on the direction shown in Figure 13.
The sketch map of use Figure 12 describes through the power that electromagnetic force receives the L shaped gas insulated bus of existing structure shown in Figure 9.Electromagnetic force is a distributed load; If but for explanation is oversimplified as waiting represent making a concerted effort that distribution loads; Then by distance L 2 and make a concerted effort the be F1 of distance L 3 with respect to the electromagnetic force of distance L 1 generation; The F2 that makes a concerted effort to be of the electromagnetic force that produces with respect to distance L 2 by distance L 1, the F3 that makes a concerted effort to be of the electromagnetic force that produces with respect to L3 by L1.These make a concerted effort to produce all unidirectional moment around the rotation of A point.If consider the moment that A order, the F1 that then respectively makes a concerted effort, F2, F3 and about equally in the substantial middle portion generation of distance L 1, L2, L3.
At this, carry out detailed slightly explanation again with Fig. 9, Figure 12 and formula opposing connection A point rotating moment.Connecting portion 9 is that the rubber-like contact connects, 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 a free end.Connecting portion 11 too, so the D of Figure 12 point also becomes free end.L shaped conductor 5 and electrode 3

Thus, the connecting portion 11 of length direction conductor 7 is formed in the central shaft CL with length direction conductor 7
1On the identical axle, another connecting portion 9 is formed in the central shaft CL with radial conductor 5A
2On the identical axle.
Central shaft CL through length direction conductor 7

As stated, according to this execution mode 3, can provide the drawing that makes set bolt to load to minimum, suppress L shaped gas insulated bus because of the electromagnetic force influence of short-time current generation.
[variation of execution mode 3]
What Fig. 7 represented is the example that also is applicable to following gas insulated bus: the length direction conductor 7 that is positioned at connecting portion 9 sides is prolonged to jar peristome 1b side, and setting is fastened on the insulating cell 2 that replaces inaccessible lid 4 to be provided with
3Embedded electrode 3
3On bonding conductor 10A, via contact chip 8
3The pole shape contact 7 that connects length direction conductor 7
1With this bonding conductor 10A, has the roughly conductor structure of the T font of quadrature thus.
And though not shown, the conductor structure of the T font of Fig. 7 also can change to criss-cross conductor structure.
[execution mode 4]
More than the gas insulated bus in the variation (Fig. 7) of the execution mode 1 (Fig. 1) of explanation and even execution mode 3 is to be applicable to the example of in a jar, taking in the phase structure of a bus, but this execution mode 4 is applicable to the blanket structure of the so-called three-phase of the bus of in a jar, taking in three-phase.Below, specify with reference to Fig. 8.
Fig. 8 is the figure of assembling process of gas insulated bus of the blanket structure of three-phase of expression this execution mode 4.Need to prove, omitted length direction conductor 7 and connecting portion 9 in the jar 1 among Fig. 8.
Below, contrast the L shaped conductor of existing shape shown in Figure 10, the assembling sequence of the gas insulated bus of this execution mode 4 is described.
With fixed radial conductor 5A and insulating cell 2
2The conductor assembled part be installed to jar 1 o'clock, need assemble through jar peristome 1c.In the L shaped conductor 5 of existing shape shown in Figure 10, when the X of L shaped conductor 5 is partly inserted jar peristome 1c,, it is turned clockwise in order not make its damaged, assembling difficulty height and assembling operation be spended time also.
Therefore but as shown in Figure 8, the radial conductor 5A of the gas insulated bus of this execution mode 4 is a straight line, does not have general curved among Figure 10 to become the X part of 90 degree, and assembling becomes easily, can shorten the activity duration of assembling.And, shown in figure 11 in the L shaped conductor 5 of existing shape, can not carry out Visual Confirmation from jar peristome 1c at connecting portion 9, therefore final joint (docking) only can carry out the connecting portion 11 of Visual Confirmation from jar peristome 1a side.
To this; In this execution mode 4; Identical with Fig. 6 of aforesaid execution mode 3, connecting portion 9 is arranged at the intersection point of radial conductor 5A and length direction conductor 7, therefore also can carry out the Visual Confirmation of connecting portion 9 from jar peristome 1c; Final joint can be connecting portion 9 with connecting portion 11 both, thereby can improve packaging efficiency.
Through above structure, when can shortening the assembling operation time, also can make the conductor shape miniaturization, thereby cheap gas insulated bus can be provided.
[variation of execution mode 5]
This structure also can be applicable to the gas insulated bus that has like the conductor structure of the T font of the roughly quadrature among Fig. 7.And, also can be applied to criss-cross conductor structure.
According to the execution mode of above explanation, diminish for the drawing load of bolt radial conductor, that produce because of electromagnetic force, the conductor diameter of radial conductor is minimized.
