Embodiment
Below, with reference to accompanying drawing best example of the present invention is described, and put on same-sign and describe for member identical in each example, position or suitable member, position.
[example 1]
Fig. 1 is the vertical view of the isolated bus system of the invention process form 1, and Fig. 2 is the cutaway view along the II-II line of Fig. 1.
Isolated bus of the present invention system has: be installed on the housing 1 as the insulated switchgear device of electric equipment respectively, the T type lining 2 of inner conductor 2a arranged; Between each T type lining 2 of adjacency, be provided with a plurality of buses unit 3 of mutual bus-bars conductor 3a axis unanimity; But the connection of connecting hole 4a of end contact separation, slip from T type lining 2 to axis direction that can move, have in both sides relative each bus-bars conductor 3a in is with conductor 4; Be inlaid in the insulation embolism 5 among the hole 2d of formed truncated cone on the T type lining 2; The screw 6 as fastener that is fastenedly connected with conductor 4 and inner conductor 2a will be connected; Be located at the ring flange 8 of T type lining 2 sides of each bus unit 3; And connect each ring flange 8 of a pair of bus unit 3 of clamping T type lining 2, connect the jockey of a pair of bus unit 3 by T type lining 2.
Connect with conductor 4 and have a pair of connecting hole 4a that can slide therein in the end of bus-bars conductor 3a.On the internal perisporium of this connecting hole 4a, be formed with groove 4b.In this groove 4b, as shown in Figure 3, be installed with and make circular helical spring contact 7, utilize this contact 7 that connection is electrically connected with bus-bars conductor 3a more reliably with conductor 4.
A pair of bus unit 3, utilize ring flange 8, break-through bolt 9 and nut 10 and be connected coaxial on.Ring flange 8 constitutes by making horseshoe-shaped a pair of flange disc 11 as Fig. 4～shown in Figure 6.Flange disc 11 have in-and-out bolt 9 through hole 11a, connect a pair of ring flange 8 mutual connecting hole 11b and screw 11c.A pair of ring flange 8 with connecting connecting hole 11b, being screwed on the bolt 11d among the screw 11c, surrounds respectively around the end of relative a pair of bus unit 3.
Jockey is made of break-through bolt 9 and nut 10, as shown in Figure 7, the stage portion butt of packing ring 20 and break-through bolt 9, screw togather by the end that makes nut 10 and break-through bolt 9 on this packing ring 20, bus unit 3 passes through 2 combinations of T type lining each other, again, and the insulator interface of T type lining 2 and the insulator interface of bus unit 3, accompany insulating oil fat and carry out crimping, realize the interface insulation.
In addition, at this moment, utilize inner conductive layer 5a, electric field to relax the radially expansion section A of shielding part 2c and inner conductive layer 3b, make to comprise that bus-bars conductor 3a obtains relaxing or shielding (Japanese: シ one Le De) with the junction surface electric field that is connected with conductor 4 junction surfaces.
Then, the order of connection to the isolated bus system median generatrix unit 3 of said structure describes.
At first, in Fig. 8, under the state after the embolism 5 that will insulate is opened, operation makes and connects with conductor 4 relative to the slip of the end of side's bus-bars conductor 3a and after the direction of arrow B moves by hand from the 2d of hole, the opposing party's bus unit that should connect 3 is moved to the arrow C direction, make the mutual axis of bus-bars conductor 3a that should connect become unanimity.This operation is carried out each the bus unit 3 between the T type lining 2 of adjacency.In addition, at this moment on bus unit 3, be provided with ring flange 8.
Then, operation makes and connects with conductor 4 relative to the slip of the opposing party's bus-bars conductor 3a end and after the direction of arrow D moves by hand from the 2d of hole, and the bus-bars conductor 3a of adjacency is connected each other.This operation is also carried out each bus unit 3.
Then, utilizing screw 6 will connect with conductor 4 is connected with inner conductor 2a.
Then break-through bolt 9 is run through through hole 11a, the end of nut 10 with bolt 9 screwed togather, connect by T type lining 2 each bus unit 3 with adjacency by packing ring 20.
At last, accompany the insulating oil fat embolism 5 that will insulate and be inlaid among the hole 2d of T type lining 2, bolt 13 spiral shells are contained in the top of T type lining 2, make insulation embolism 5 fixing with T type lining 2 by pressing plate 12.
In addition, in the isolated bus system,, need only and carry out just passable with the order opposite with above-mentioned operation with the operation that the connection of bus unit 3 is removed.
As mentioned above, adopt the isolated bus system of this example, but can move and have respectively in both sides and being connected of the connecting hole 4a of bus-bars conductor 3a end contact separation, slip to axis direction with conductor 4 owing in T type lining 2, have, so will and the housing 1 established in housing 1 occasion of being extracted arbitrarily, other housing 1 is extracted this housing 1 movably.
In installing during gas insulation opening and closing arrangement,, the mutual axis unanimity of the bus-bars conductor 3a of adjacency can be automatically made, the position alignment of axis can be carried out simply by the end of bus-bars conductor 3a is inserted to intercommunicating pore 4a again.
[example 2]
Fig. 9 is the major part cutaway view of the isolated bus system of example 2 of the present invention.
In this example, connect with conductor 21, as Figure 10, shown in Figure 11, make C shape, screw 6 spiral shells are contained on the inner conductor 2a of T type lining 2 by section shape with pars intermedia, make to connect and connect airtight with conductor 21 and the end of bus-bars conductor 3a.Therefore, in this occasion, do not need as example 1 required groove 4b, contact 7.
In addition, connect and use conductor, both can constitute, also the section shape of connection with the pars intermedia of conductor can be made C shape, with clip open side is fastenedly connected by be divided into two two members that form along axis direction.
In addition, in above-mentioned each example 1,2, be described for gas insulation opening and closing arrangement, but the present invention is not limited thereto certainly, also can be applicable in the isolated bus system of the distribution board that is configured in complete set of equipments or the building and transformer as electric equipment.
As mentioned above, the present invention can be applicable to and the housing of a plurality of electric equipments of establishing between the isolated bus unit that connects with isolated bus.
