A terminals side at circuit breaker 1 is provided with current transformer 5, and this current transformer 5 is connected with insulating sleeve 4a; In the another terminal side of circuit breaker 1, be connected with the end of cutter 2a, 2b respectively by grounding opening-closing device 6; The other end of these two cutter 2a, 2b is connected with insulating sleeve 4b, 4c respectively, constitutes the insulated switchgear device with this.
Fig. 1 and Fig. 2 are the front elevation and the plane graphs of the gas insulation opening and closing arrangement of the above-mentioned loop of expression formation.
An axial end of this difference connector 3 extends to the inside one side of circuit breaker closed container 7, is connected with cutter closed container 10 in this end, and this cutter closed container 10 has the main part that approximate vertical is extended.In this cutter closed container 10, also enclose the insulation medium, constitute cutter 2a.The bottom of the insulating sleeve 4b of the top of the cutter closed container 10 of cutter 2a and approximate vertical configuration is adjacent.Axial the other end of above-mentioned difference connector 3 extends to front one side of circuit breaker closed container 7, an end that is connecting the cutter closed container 13 of approximate horizontal extension in this other end, in this cutter closed container 13, also enclose the insulation medium, constitute cutter 2b and grounding opening-closing device 6.The bottom of the insulating sleeve 4c of tilted configuration is connected with the other end of this cutter closed container 13.
Each insulating sleeve 4a～4c is provided with head air terminal 15～17 at the head of magnetic tube, disposes center conductor on the approximate centre axle in this magnetic tube, and the base portion side of this magnetic tube has to connect uses closed container.As shown in Figures 1 and 2, in order to apply flexibly the air insulation distance between each insulating sleeve 4a, 4b effectively, the direction of the assurance air insulation distance between direction of principal axis and insulating sleeve 4a, the 4b of circuit breaker closed container 7 of circuit breaker 1 is configured with being consistent.As shown in Figure 2, suppose to have the notional vertical plane 11 of the central shaft of the circuit breaker closed container 7 by this circuit breaker 1, on this notional vertical plane 11, dispose the head air terminal 15 of insulating sleeve 4a and for the insulating sleeve 4a of the center conductor in the magnetic tube is set.Supposing has the notional vertical plane 12 of closing on and being parallel to each other with this notional vertical plane 11, disposes the head air terminal 16 of insulating sleeve 4b and for the insulating sleeve 4b of the center conductor in the magnetic tube is set on this notional vertical plane 12.In addition, supposing has the notional vertical plane 14 of closing on and being parallel to each other with this notional vertical plane 11, disposes the head air terminal 17 of insulating sleeve 4c and for the insulating sleeve 4c of the center conductor in the magnetic tube is set on this notional vertical plane 14.
The head air terminal 15 of insulating sleeve 4a links to each other with supply lines not shown in the figures, and the head air terminal 16,17 of insulating sleeve 4b, the 4c of cutter 2a, 2b side links to each other with dual air bus not shown in the figures respectively.Guarantee air insulation distance L 1, the L2 corresponding between the head air terminal 15～17 of each insulating sleeve 4a, 4b, 4c respectively with the rated voltage of system, usually, the insulation distance of enclosing the insulation medium in each closed container than the air insulation of atmosphere apart from weak point, therefore, each insulating sleeve 4a～4c disposes obliquely, makes between its head side wideer than its underpart side.In this structure, the insulating sleeve 4b that is positioned at the centre position is generally vertical, in contrast to this, the insulating sleeve 4a, the 4c that are positioned at both sides dispose obliquely, make its head air terminal 15,17 away from head air terminal 16, can be easy to guarantee and head air terminal 16 between air insulation distance L 1, L2.The angle of inclination of these insulating sleeves 4a, 4c is according to decisions such as desired air insulation distance or the anti-mechanical strengths of shaking.
Fig. 3 is an end view of observing above-mentioned gas insulated switchgear device from operating portion 8 sides of above-mentioned circuit breaker 1.As can be seen from this figure, suppose to have the notional vertical plane 11,12,14 of almost parallel, on this notional vertical plane 11,12,14, dispose each insulating sleeve 4a, 4b, 4c at each respectively dispersedly, at least on each this notional vertical plane 11,12,14, can dispose the head air terminal 15～17 of each insulating sleeve 4a, 4b, 4c dispersedly, but, in this structure, head air terminal 15～17 not only can be set, the center conductor in the porcelain tube also can be set respectively.
Such gas insulation opening and closing arrangement, because insulating sleeve 4a, 4b, 4c are configured in respectively on different three notional vertical plane 11,12,14 dispersedly, compare with the situation of all insulating sleeve 4a～4c of configuration in same notional vertical plane, can make gas insulation opening and closing arrangement connect miniaturization on axial between insulating sleeve 4a and the insulating sleeve 4c.This is that the head air terminal 15～17 of each insulating sleeve 4a, 4b, 4c is configured to staggered because insulating sleeve 4a～4c shown in Figure 2 is configured in respectively on different three notional vertical plane 11,12,14 dispersedly; And on fore-and-aft direction, also can guarantee the air insulation distance, and this is because observe from plane shown in Figure 1, the air insulation distance is greater than head air terminal distance L 1, the L2 of each insulating sleeve 4a～4c on the fore-and-aft direction.In addition, the part that circuit breaker 1, cutter 2a, 2b and current transformer 5 etc. are constituted is easy to be transported to electric substation under production plant's assembling all-in-one-piece state.Certainly, the height that comprises the gas insulation opening and closing arrangement of insulating sleeve 4a～4c is lower than under the situation of carrying maximum height limit, the gas insulation opening and closing arrangement that comprises this insulating sleeve 4a～4c can be become one and carry.
In addition, above-mentioned effect also can obtain the head air terminal 15～17 of each insulating sleeve 4a～4c is made the structure of roughly the same height, but, three thoroughly do away with the insulating sleeve 4b that is positioned at pars intermedia among edge sleeve pipe 4a～4c, its underpart constitutes cutter 2a, and generally perpendicularly hold up, therefore, its head air terminal 16 is positioned at the more position of top than two other insulating sleeve 4a, 4c.Thereby, gas insulation opening and closing arrangement can be not elongated on the direction of the air insulation distance of guaranteeing to connect insulating sleeve 4a and insulating sleeve 4c, the additional air insulation distance that above-below direction is arranged between the head air terminal 15,17 of the head air terminal 16 of insulating sleeve 4b and adjacent insulating sleeve 4a, 4c, can guarantee bigger air insulation distance, by means of all small-sized gas insulation opening and closing arrangements of this conduct, can keep that good air insulation distance is arranged between insulating sleeve 4a～4c.
In addition, above-mentioned gas insulated switchgear device is owing to be provided with difference connector 3, vertical and the approximate horizontal ground configuration of the central axis of this difference connector 3 and circuit breaker closed container 7, simultaneously, with another distolateral linking to each other of circuit breaker 1, therefore, change the axial length of this difference connector 3, can change this difference connector 3 and cutter closed container 10,13 link position, whereby, can set each insulating sleeve 4b arbitrarily, the configuration notional vertical plane 12 of 4c, 14, the result, also can guarantee the air insulation distance on fore-and-aft direction each other between the head air terminal 15～17 of each insulating sleeve 4a～4c, be easy to the setting air insulation distance.
Three positions of thoroughly doing away with the head air terminal 15～17 of edge sleeve pipe 4a～4c also can be as shown in Figure 2, head air terminal 15,17 mutually away from the direction updip tiltedly dispose insulating sleeve 4a, 4c after, with this head air terminal 15,17 equidistant position configuration insulating sleeve 4b, head air terminal 16 is positioned on this insulating sleeve 4b.In this case, insulating sleeve 4b is not limited to this, not necessarily wants vertical, even under situation about tilting, also can determine its base portion side position, makes the angle of inclination of its angle of inclination less than insulating sleeve 4a, 4c, and becomes the form of approximate vertical.
Do not allow gas insulation opening and closing arrangement maximize, further strengthen three thoroughly do away with between the head air terminal 15～17 of edge sleeve pipe 4a～4c air insulation apart from the time, the notional vertical plane 12 of the head air terminal 16 of configuration insulating sleeve 4b also can move towards the direction of the notional vertical plane 11 that comprises insulating sleeve 4a further away from each other.But, the gas insulation opening and closing arrangement of reality shown in Figure 4 is owing to be to be arranged side by side the three-phase part to constitute, therefore, also must consider the air insulation distance L 3 between the phase place, thereby, as can be seen from this figure, different three notional vertical plane 11,12,14 that dispose insulating sleeve 4a～4c respectively are consistent with the direction that is arranged side by side of the three-phase part of gas insulation opening and closing arrangement, and the insulating sleeve 4b that is configured on the notional vertical plane 12 that is positioned at the centre position is generally vertical.
Therefore, insulating sleeve 4aU, the 4cU of U phase, its head air terminal 15,17 similarly tilts and away from the head air terminal 16 of the insulating sleeve 4bU of U phase the time, and this head air terminal 15,17 tilts and similarly away from the head air terminal 16 of the insulating sleeve 4bV of V phase.This relation for V and W mutually too.Thereby, between the head air terminal 16 of the insulating sleeve 4bU of U phase and the insulating sleeve 4bV of V phase and between the head air terminal 16 of the insulating sleeve 4bW of the insulating sleeve 4bV of V phase and W phase, only just can guarantee and essentially identical in the past phase place between air insulation distance L 3 this point, just can keep the insulating properties between each phase place well, and, at the area that is provided with that also can dwindle gas insulation opening and closing arrangement on the direction that is arranged side by side of three-phase part.
Fig. 5 and Fig. 6 are the plane graph and the end views of the gas insulation opening and closing arrangement of another embodiment of the present invention.
Similarly be connected on the terminal of the circuit breaker 1 that the closed container 7 of approximate horizontal configuration constitutes the bottom of the insulating sleeve 4a of tilted configuration with the situation of Fig. 1～form of implementation shown in Figure 3.Relative therewith, another terminal of circuit breaker 1 and the lower side contact of cutter 2a link together, cutter 2a by on another top that is connected to this circuit breaker closed container 7, the cutter closed container 10 that extends of approximate vertical constitutes, the insulating sleeve 4b of approximate vertical links to each other with the top of this cutter closed container 10, and the upper side contact of cutter 2a is connected with the center conductor of insulating sleeve 4b.The front face side of cutter closed container 10 links to each other with the inside side of the cutter closed container 13 of cutter 2b, and the lower side contact of this cutter 2b links to each other with the lower side contact of cutter 2a, constitutes grounding opening-closing device 6 on this part.This cutter closed container 13 is connected on the closed container with the situation bending of the base portion side of the insulating sleeve 4c of horizontal arrangement similarly of the form of implementation of Fig. 1～shown in Figure 3, and the contact of top one side of cutter 2b and the center conductor of insulating sleeve 4c are linked together.
Therefore, insulating sleeve 4b is vertical substantially, relative therewith, insulating sleeve 4a is configured in the side of its head air terminal 15 away from the head air terminal 16 of insulating sleeve 4b obliquely, in addition, insulating sleeve 4c also is configured in the side of its head air terminal 17 away from the head air terminal 16 of insulating sleeve 4b obliquely.And insulating sleeve 4a and insulating sleeve 4b are arranged in roughly the same notional vertical plane 11, with the different notional vertical plane 14 of these notional vertical plane 11 almost parallels in, configuration insulating sleeve 4c.
According to this gas insulation opening and closing arrangement, because insulating sleeve 4a～4c is configured on parallel two notional vertical plane 11,14 respectively, therefore, compare with the situation that all insulating sleeve 4a～4c are configured in the same notional vertical plane, can make gas insulation opening and closing arrangement connect miniaturization on axial between insulating sleeve 4a and the insulating sleeve 4c.And since insulating sleeve 4a and insulating sleeve 4b be positioned on the same notional vertical plane 11, thereby, can omit the difference connector 3 of approximate horizontal shown in Figure 2, dwindle its axial length, and, notional vertical plane 11,14 be arranged side by side on the direction, be on the direction between the phase place of Fig. 4, obtain small-sized gas insulation opening and closing arrangement.
In addition, in this form of implementation, be arranged in the insulating sleeve 4b of the pars intermedia of three eradication edge sleeve pipe 4a～4c, its underpart also is connected on the circuit breaker closed container 7 by the cutter 2a with cutter closed container 10, and, generally perpendicularly hold up, thereby, its head air terminal 16 and other two thoroughly does away with edge sleeve pipe 4a, 4c and compares, and is positioned at the more position of top.Thereby, gas insulation opening and closing arrangement can be not elongated on the direction that connects insulating sleeve 4a and insulating sleeve 4c, the additional air insulation distance that above-below direction is arranged between the head air terminal 15,17 of the head air terminal 16 of insulating sleeve 4b and adjacent insulating sleeve 4a, 4c, can guarantee bigger air insulation distance, by means of all small-sized gas insulation opening and closing arrangements of this conduct, can keep good air insulation distance.

Gas insulation opening and closing arrangement according to this formation, though grounding opening-closing device shown in Figure 14 6 arranged in that cutter closed container 13a is additional, but, because cutter 2a is roughly identical formation with the assembly of insulating sleeve 4b and the assembly of cutter 2b and insulating sleeve 4c, therefore, can realize the generalization of parts, all can be with the low cost manufacturing.Certainly, because insulating sleeve 4a～4c also is configured on the parallel respectively different notional vertical plane 11,12,14, thereby, compare with the situation that all insulating sleeve 4a～4c are configured in the same notional vertical plane, on fore-and-aft direction, also can increase the air insulation distance, can make gas insulation opening and closing arrangement connect miniaturization on axial between insulating sleeve 4a and the insulating sleeve 4c.
In addition, in this form of implementation, be arranged in the insulating sleeve 4b of the pars intermedia of three eradication edge sleeve pipe 4a～4c, its underpart disposes cutter 2a, thereby its head air terminal 16 is compared with another insulating sleeve 4a, is positioned at the more position of top.And, because cutter 2a is roughly identical formation with the assembly of insulating sleeve 4b and the assembly of cutter 2b and insulating sleeve 4c, even in use, the insulating sleeve 4b that is positioned at pars intermedia generally perpendicularly holds up, therefore, its head air terminal 16 and other two thoroughly does away with edge sleeve pipe 4a, 4c and compares, and is positioned at the more position of top.Thereby, gas insulation opening and closing arrangement can be not elongated on the direction of the assurance air insulation distance that connects insulating sleeve 4a and insulating sleeve 4c, the additional air insulation distance that fore-and-aft direction and above-below direction are arranged between the head air terminal 15,17 of the head air terminal 16 of insulating sleeve 4b and adjacent insulating sleeve 4a, 4c, can guarantee bigger air insulation distance, by means of all small-sized gas insulation opening and closing arrangements of this conduct, can keep good air insulation distance.
Figure 12 and Figure 13 are the plane graph and the end views of the gas insulation opening and closing arrangement of expression a further embodiment form of the present invention.
This form of implementation adopts the cutter 2b of Fig. 9 explanation and the straight line assembly of insulating sleeve 4c in Fig. 5 and gas insulation opening and closing arrangement shown in Figure 6, therefore, similarly be connected on the terminal of the circuit breaker 1 that the circuit breaker closed container 7 of approximate horizontal configuration constitutes the bottom of the insulating sleeve 4a of tilted configuration with the situation of previous form of implementation.Relative therewith, another terminal of circuit breaker 1 and the lower side contact of cutter 2a link together, the cutter closed container 10 that cutter 2a is extended by the approximate vertical on another top that is connected to this circuit breaker closed container 7 constitutes, be connected with the insulating sleeve 4b of approximate vertical on the top of this cutter closed container 10, the upper side contact of this cutter 2a is connected with the center conductor of insulating sleeve 4a.The inside side of cutter closed container 13 links to each other with the front face side of cutter closed container 10, and the lower side contact of this cutter 2b links to each other with the lower side contact of cutter 2a.This cutter closed container 13 is same with the situation of form of implementation shown in Figure 9, the central shaft of its central shaft and insulating sleeve 4c as one man constitutes linear structure, and the center conductor of the insulating sleeve 4c that will be connected with its top and the top of cutter 2b one side contact link together.
In this form of implementation, the face-off portion of cutter closed container 10 and cutter closed container 13 is connected, normally carry out bolted with formed flange connector face on two closed containers, so, can select arbitrarily with this flange connector face between the angle that is consistent, thereby, be easy to support obliquely insulating sleeve 4c side.Insulating sleeve 4b is vertical substantially, relative therewith, insulating sleeve 4a utilizes this formation, its head air terminal 15 is away from the lopsidedness ground configuration of the head air terminal 16 of insulating sleeve 4b, in addition, insulating sleeve 4c also is configured in the side of its head air terminal 17 away from the head air terminal 16 of insulating sleeve 4b obliquely.And insulating sleeve 4a and insulating sleeve 4b are arranged in roughly the same notional vertical plane 11, with the different notional vertical plane 14 of these notional vertical plane 11 almost parallels in, configuration insulating sleeve 4c.
According to this gas insulation opening and closing arrangement, because insulating sleeve 4a～4c also is configured on parallel respectively two notional vertical plane 11,14, thereby, compare with the situation that all insulating sleeve 4a～4c are configured in the same notional vertical plane, owing on fore-and-aft direction, add the air insulation distance arranged, therefore, can make gas insulation opening and closing arrangement connect miniaturization on axial between insulating sleeve 4a and the insulating sleeve 4c.In addition,, therefore, can realize the generalization of parts because cutter 2a is roughly identical formation with the assembly of insulating sleeve 4b and the assembly of cutter 2b and insulating sleeve 4c, all can be with the low cost manufacturing.
In addition, in this form of implementation, be arranged in the insulating sleeve 4b of the pars intermedia of three eradication edge sleeve pipe 4a～4c, its underpart also disposes cutter 2a, and this insulating sleeve 4b links to each other with the top of circuit breaker closed container 7, and, generally perpendicularly hold up, thereby its head air terminal 16 and other two thoroughly does away with edge sleeve pipe 4a, 4c and compares, and is positioned at the more position of top.Thereby, gas insulation opening and closing arrangement can be not elongated on the direction that connects insulating sleeve 4a and insulating sleeve 4c, the additional air insulation distance that above-below direction is arranged between the head air terminal 15,17 of the head air terminal 16 of insulating sleeve 4b and adjacent insulating sleeve 4a, 4c, can guarantee bigger air insulation distance, by means of all small-sized gas insulation opening and closing arrangements of this conduct, can between insulating sleeve, keep good air insulation distance.
This cutter closed container 10 is roughly identical formation with the assembly of insulating sleeve 4b and the assembly of cutter closed container 13 and insulating sleeve 4c, and this structure also is applicable to form of implementation shown in Figure 7, is that adjacent insulating sleeve alternately is configured in the situation in the different notional vertical plane respectively.In addition, though the present invention utilizes the cylindric circuit breaker closed container 7 of approximate horizontal to constitute circuit breakers 1,, also can use the circuit breaker closed container 7 of the different shape that comprises vertical structure.In this case, the insulating sleeve 4a that is connected with an end of circuit breaker 1 might not be configured in the notional vertical plane by the central axis of circuit breaker closed container 7, also can be in other notional vertical plane configurations, for example adopt the formation of Fig. 5, configuration insulating sleeve 4a in notional vertical plane 14, and, cutter 2a, the 2b that is connected with the other end of circuit breaker 1 also not necessarily will be connected the end top of circuit breaker closed container 7, can also be directly or be connected the various positions of circuit breaker closed container 7 by difference connector 3.In addition, insulating sleeve 4a～4c, its head air terminal 15～17 with and base portion side be configured in respectively in the identical notional vertical plane, but, not only on the direction of the assurance air insulation distance between each insulating sleeve 4a～4c, and, insulating sleeve is tilted being arranged side by side on the direction etc. between the three-phase, thereby, can be configured in each notional vertical plane to each head air terminal of major general.
In each form of implementation of above explanation, although understand the gas insulation opening and closing arrangement that constitutes according to single-phase loop diagram shown in Figure 14, but, the gas insulation opening and closing arrangement that be applicable to that also the insulating sleeve 4a side at the circuit breaker 1 of this Figure 14 connects the 3rd cutter, be provided with current transformer 5 in the both sides of circuit breaker 1, the change loop constitutes.Further, when connecting three circuit breakers respectively in both sides, between this circuit breaker, hold up insulating sleeve, hold up in 11/2 the circuit breaker mode of insulating sleeve in any one all end with cutter, at least three thoroughly do away with the edge sleeve pipe disposes with closing on, in addition, even connect in the ring busbars mode of ring-type at a plurality of circuit breakers, when between each circuit breaker, holding up insulating sleeve, at least three thoroughly do away with the edge sleeve pipe disposes with closing on, similarly can adopt the present invention with above-mentioned air duplicate bus-bar mode.
