As described above, sidepiece wallboard 43, 44 are formed as arc-shaped in the horizontal direction of fore-and-aft direction and the Y-direction of X-direction and above-below direction, and by these ends 44a in the horizontal direction and X-direction of the fore-and-aft direction of the 1st casing 1, 44b be formed as than anterior end plate 45 and rear portion end plate 46 Breadth Maximum more to inward side to arc-shaped, and by these ends 44c on the above-below direction and Y direction of the 1st casing 1, 44d be formed as than top wallboard 41 Breadth Maximum more to inward side to arc-shaped, form the 1st casing 1 thus, thus can obtain lightweight, the gas-insulated switchgear device that intensity is large and compact.
In addition, sidepiece wallboard 43, 44 are formed as arc-shaped in the horizontal direction of fore-and-aft direction and the Y-direction of X-direction and above-below direction, and by these ends 44a in the horizontal direction and X-direction of the fore-and-aft direction of the 1st casing 1, 44b be formed as than anterior end plate 45 and rear portion end plate 46 Breadth Maximum more to inward side to arc-shaped, and by these ends 44c on the above-below direction and Y direction of the 1st casing 1, 44d be formed as than top wallboard 41 Breadth Maximum more to inward side to arc-shaped, form the 1st casing 1 thus, and place the 2nd casing 17 at the upper side of the 1st casing 1, thus intensity increase can be obtained and the gas-insulated switchgear device that the stepped construction of casing is more compact can be made.
Roughly the same or less than it by the size making to be formed as on the Breadth Maximum direction of the sidepiece wallboard 43 of arc-shaped and the central portion of sidepiece wallboard 44 and the top of arc-shaped and anterior end plate 45 and rear portion end plate 46, thus can be configured more compact when transversely arranged configuration gas-insulated switchgear device.
Anterior end plate 45 is by flange plate 53, engage with the lower side rear portion of flange plate 53 and extend downwards and the pedal 54 more outstanding than bottom wallboard 42, fastening hole 55, and handle hole 56 is formed, pedal 54 is configured to give prominence to more to the lower side than bottom wallboard 42, rear portion end plate 46 is by rear seben 57, engage with the lower side rear portion of rear seben 57 and extend downwards and the pedal 58 more outstanding than bottom wallboard 42, and form for the hole 59 of stube cable 38, pedal 58 is configured to give prominence to more to the lower side than bottom wallboard 42, thus make the pedal 54 of anterior end plate 45 and rear portion end plate 46 and pedal 58 be configured to give prominence to more to the lower side than bottom wallboard 42, therefore, the pedal 54 of anterior end plate 45 and rear portion end plate 46 and pedal 58 can be utilized to make the 1st casing 1 separate support and are fixed in the basal part of gas-insulated switchgear device, thus the structure of gas-insulated switchgear device can be formed simply.
In addition, by being configured to protrude arc-shaped downwards by bottom wallboard 42, thus the dust in the 1st casing 1 can be pooled to the central lower of the 1st casing 1.Thus, dust is there is not between the sidepiece wallboard 43,44 of charging part both sides phase and the 1st casing 1, thus space insulation distance between shortening over the ground, the width of the 1st casing 1 can be reduced, and due to by means of only making charging part mesophase spherule bottom protrude arc-shaped in downward direction, thus the bottom of the 1st casing 1 makes dust collect, thus ensure that mesophase spherule over the ground between space insulation distance, and the width of the bottom of the 1st casing 1 can be reduced, therefore, it is possible to make the 1st casing 1 miniaturization (overall dimension, volume).
The section of bottom wallboard 42 is formed as U-shaped, two wall top 42a, 42b of its underpart wallboard 42 erect upward, and to reduce and elongated portion 43e, the 44e of the sidepiece wallboard 43 extended to the lower side and sidepiece wallboard 44 engage to center direction with arc-shaped with width from top, these junction surfaces are configured to the inner side depression to the 1st casing 1 and extend to the concavity portion 60,61 at rear portion from the front portion of the 1st casing 1, thus the intensity utilizing these concavity portions 60,61 can realize the 1st casing 1 improves.
In addition, by making bottom wallboard 42 be formed as U-shaped, two wall top 42a, 42b of the U-shaped of bottom wallboard 42 can be made easily to engage with elongated portion 43e, the 44e of sidepiece wallboard 43 and sidepiece wallboard 44, easily forming concavity portion 60,61 thus.
In addition, formed by respectively with the notch 44f that the right lower quadrant of size e and size f counter-lateral quadrents wallboard 43 and sidepiece wallboard 44 and lower left quarter carry out cutting and obtain, 44g, and be configured so that the length being shorter in length than the fore-and-aft direction of sidepiece wallboard 43 and sidepiece wallboard 44 of the fore-and-aft direction of bottom wallboard 42, the anterior position of lower side of end plate 45 and the position of the lower side of rear portion end plate 46 are positioned at than anterior end plate 45 and rear portion end plate 46 more in the inner part, the volume of the 1st casing 1 can be reduced thus, and the intensity that can realize the 1st casing 1 improves, the setting area of the 1st casing 1 can be reduced.
Sidepiece wallboard 43 and sidepiece wallboard 44 have the shape of the symmetrical line symmetry of the above-below direction axle of the pars intermedia of the fore-and-aft direction relative to the 1st casing 1, thus as being configured at the structure of sidepiece wallboard of sidepiece wallboard 43 and sidepiece wallboard 44, a kind of parts can be shared.Therefore, diel when manufacturing sidepiece wallboard 43 and sidepiece wallboard 44 can use same, identical component can be used for sidepiece wallboard 43 and the sidepiece wallboard 44 of the left and right sides, thus, variety of components can be cut down, also can cut down the kind of the diel of parts manufacture, and then can manufacturing cost be cut down.
The top wallboard 41 of the 1st casing 1 is configured with towards the Width of the 1st casing 1 and strengthens skeleton 51,52, via enhancing skeleton 51,52, the 2nd casing 17 is supported, therefore, the loading being positioned over the 2nd casing 17 of the upper side of the 1st casing 1 can easily be transmitted via enhancing skeleton 51,52, and support the 2nd casing 17, thus the stepped construction of multiple casing becomes simple.
In addition, the present invention freely can combine execution mode in this scope of invention, or carries out suitable distortion, omission to execution mode.
Industrial practicality
The present invention by being formed as arc-shaped by the horizontal direction of the both sides wallboard of casing before and after casing and above-below direction, thus is suitable for realizing lightweight and compact gas-insulated switchgear device.
