Definitions

• the invention relates to insulating supports for vacuum switches with drive devices for installation in switchgear assemblies, in particular in medium-voltage switchgear assemblies, the insulating supports each being formed from a flat-bed-like plastic profile, one end region of which has a first fastening leg with slowly symmetrically arranged screw bearings for releasable connection to the Vacuum switches and their second end area are equipped with a second fastening leg with likewise slowly symmetrical screw bearings for detachable connection to the switchgear.
• Such defined insulating supports for vacuum switches are known from DE-U 94 09 006.
• the vacuum switches are realized here by vacuum interrupters, which - each surrounded by two insulating supports - are installed in gas-filled containers of switchgear. Each vacuum interrupter practically has its own insulating housing made up of two insulation supports.
• the vacuum switching tubes for switching the phases are controlled by the common drive device.
• Vacuum protections in which the switching frequency is a multiple compared to the vacuum interrupters when the switching voltage is lower, however, are known to be housed in blocks in a common insulating housing.
• several vacuum protection devices are controlled simultaneously by the common drive device.
• the object on which the invention is based is to define a fastening concept for vacuum protections by means of which the biodiversity of the fastening elements compared to the b Isherorganizedl cozy standard I erhebl is reduced without the usual in this technique high S icherheitsan petitionen limit.
• the pole shells each have an inwardly curved enclosure profile
• the pole shells are each equipped with vacuum contactor mounting bars arranged in mirror image to each other for detachable connection to the vacuum contactors,
• pole shells are each equipped with a pole shell fastening bar for detachable connection to the switchgear
• the pole shells have a number of circumferential transverse ribs, which are approximately at right angles to the longitudinal axes of the pole shells, adapted to the voltage conditions of the vacuum contactors.
• the invention is therefore based on the knowledge that the advantages of a uniform insulating housing with great stability for vacuum contactors and the greater flexibility when installing vacuum tubes of different types combine with separately assigned insulating housings. Due to the inwardly curved enclosure profile with its number of circumferential cross ribs adapted to the respective voltage conditions, the insulating housings are also provided with sufficient dimensional stability for the vacuum contactors. This dimensional stability is further enhanced in a special way by the mirror-inverted vacuum contactor mounting webs and the vacuum contactor mounting web.
• the features are 2.1 the pole shells are each provided with a guide web in the area of the force effect of the drive device,
• the inwardly facing free ends of the guide web each have a guide recess, provided.
• a further refinement of the invention provides feature 3.1 that the inwardly curved enclosure profile of the pole shells is dimensioned such that vacuum contactors with different dimensions and spacing from one another are installed in the switchgear with pole shells of the same type. Pole shells designed in this way can be installed in the switchgear without different design changes to the same vacuum protection devices of different designs.
• Figure 1 is a front view of the interior of the
• FIG. 1 shows the pole shell PS with the longitudinal axis LA.
• the upper and the lower vacuum protection fastening webs VGL and VG2 can be seen, which are arranged in mirror image to one another.
• the vacuum protection devices, not shown, are to be arranged between the vacuum contactor fastening webs VGl and VG2 by fastening means, also not shown.
• Under The lower vacuum contactor fastening web VG2 also has the continuous guide web FS, which is provided with a guide recess FA at the free ends pointing inwards.
• FIG. 3 shows the pole shell PS (Fig. 1) in profile section along the section line A-B (Fig. 1). From this illustration, the profile stiffeners caused by the vacuum contactor fastening webs VB1 and VB2 and the transverse ribs QR ... arranged parallel to them can be seen particularly clearly.
• the vacuum contactors between the pole shells PS (Fig. 1) are securely fastened by means of the vacuum protection mounting bars that are reinforced upwards and downwards.
