Abstract
ABSTRACT
In metal-enclosed pressurized gas-insulated high-voltage power stations the housings (1, 7), whose longitudinal axes area at an angle to each other, must often be connected to one another via an adapter (8). Two rings (19, 20) abutting one an-other at the end face serve as the adapter (8), these rings each having bores (22, 32, 23, 33) on an inner (21) and an outer (31) reference circle and each connected to the flange (9, 10) of one of the housings (1, 7) on the inner reference circle (21) and to one another on the outer reference circle (31). On one of the rings (20) the bores (32) on the outer reference circle (31) are designed as elongated holes (32), their length corresponding to half the hole spacing .beta.a2. The hole spacing on the outer reference circle (31) of the other ring (19) then amounts to half of .beta.a2 or is equal to .beta.a2 if the gas seals lie only on the ring (20) with the elongated holes (32). All angles ? .alpha. between the longitudinal axes can be set by means of the adapter (8).

Description
2C~333$
The invention relates to a metal-enclosed pressurized gas-insulated high-voltage power station whose conductors or appa-ratus are accommodated in housings in which the conductors extend essentially in the direction of the longitudinal axis of the hous-ing and in which the longitudinal axes of the housings to be con-nected together are at an angle to one another and are connected by means of a two-part adapter, whereby the housings are respec-tively connected to the adapter via flanges and fasteners pene-trating these flanges.
Such a metal-enclosed high-voltage power station can comprise apparatus and/or tubular conductors combined in switch-board sections of a specific field circuit and respectively accom-modated in housings filled with pressurized gas, particularly with SF6. It is thereby usual that the apparatus in the housings filled with pressurized gas forming part of the switchboard sec-tions be accommodated in a confined space, e.g. in buildings, whereas transformers or open-wire circuits, which can also form part of the high-voltage power station, are often located outdoors and have connaction~ spaced substantially farther apart. Gas-filled tubular conductors are often used for the connections. It is therefore necessary that the housings be connected to one an-other with their longitudinal axes extending at an angle to each other. At connecting points to one another the tubular conductors can also be at an angle between 0 to 90 between the longitudinal axes of their housings or conductors.
So as not to have to provide corresponding specially adapted housings for such break points, it is known from German Utility Model 72 33 316 to connect the housings and conductors ,, . ............ , - :

aligned at an angle to each other by means of a two-part adapter which i~ fastened with the aid of flanges to the housings to be connected together, e.g. of the field circuit and/or the tubular conductor. The known two-part adapter consists of two spherical segments, which are welded together and form the enclosure, as the housing in which the conductors are connected to one another in the centre of the spheres. During original installation this known adapter allows easy adaptation to the angle~ given between the conductors to be connected. After welding, however, this specific angle of the adapter cannot be altered.
It is the aim of the present invention to design a two-part adapter for connecting angularly aligned housings of a metal-enclosed pressurized gas-insulated high-voltage power station in - such a way that the adapter can be easily adapted to the angle, can be easily disassembled at any time and can again be adapted to another angle between 0- and 90-.
To solve this problem a metal-enclosed pressurized gas-insulated high-voltage power station of the kind named at the beginning is de~igned ln accordance with the invention such that two ringa abutting at the end face and sealed in gas-tight manner - against each other and against the flangeg serve as the adapter.
These rings each have tapped holes or throughholes on an inner and an outer reference circle and each is fastened by means of fas-teners to a flange of the housing on the inner reference circle.

additional fa~teners lie out~ide the flanges. Qn one of the ring~ the bores on the outer reference circle are designed as elongated holes, the length of which corresponds to half the hole spacing ~a2 on this outer reference circle.
The housings of the high-voltage power station with lon-gitudinal axes or conductors extending at an angle to each other are thus connected via the normal flanges of the housings by simply inserting two rings abutting one another at the end face, these rings being connected to the flange~ of the housing on the inner reference circles and to one another on the outer reference circle~.
On one of the two rings the boreg for receiving the ad-ditional fastener for connecting the rings together are designed as elongated holes. The length of these elongated holes cor-responds to half the hole spacing ~a2 of the elongated holes.
The area remaining between the elongated holes is thus the same length as the elongated holes and 18 covered by shifting the ring with the elongated holes.
It is recommended that half the hole spacing ~a2 be selected for the hole spacing ~al on the outer reference circle of the other ring. In this way one of the bores on the other ring can alway~ be aligned with the elongated hole over the entire area of displacement.
Since bores are likewise provided on the inner reference circle of the rings, these bore~ being identical in diameter and hole spacing to the bores on the flanges of the hou~ings that are to be connected together even though their longitudinal axes are at an angle ~ to each other, any angle ~ between + 90 can be set : .

by twisting the two rings of the adapter against each other. The diameter and hole spacings or the reference circle on the flange and the associated inner reference circle on the rings of the adapter to be connected to thi~ flange can thereby be selected completely independently of the conditions on the outer reference circle of the rings. Therefore, guaranteeing the gas tightness of the connection by appropriately selecting the hole spacing on the inner reference circle causes no difficulties. The gas seals can thereby be attached in any manner to one of the two end faces of the rings.
Furthermore, the hole ~pacing ~a2 of the elongated holes on the outer reference circle of one of the rings can be ad-vantageously selected in such a way that they can be added up to 180. In this case the gas seals are to be arranged only on the two end faces of the ring with the elongated hole~. The possibil-ity then exists of turning this ring with the elongated hole~ over a diameter that respectively forms the axis of symmetry. Then, in the folded position, i.e. turned 180, of the ring the elongated holes are respectively arranged mirror-inverted to the original position and this ring with elongated holes can be connected to a ring that has only half the number of bores on the outer reference circle, i.e. in which the hole spacing on the outer reference circle corresponds to the hole spacing ~a2 of the elongated holes.
'; The outer diameter of the two ring~ of the adapter can vary. The larger ring can then be utilized to attach additional fastenings, e.g. for fastening a support. The outer diameter of the flanges can also vary if the inner reference circles of the associated rings are adapted accordingly.

The flanges to which the two-part adapter is connected can be situated either on the end face or on the surface of the housings, depending on the plane in which the angle between the longitudinal axes of the housings to be connected together lies.
A particularly simple embodiment results if the flanges of the housings each have the same number of bores on the inner reference circle as if they were to be directly connected to one another.
Both rings then have the same inner reference circle with the same number of bores.
Contaminants or moisture can be advantageously prevented from entering via the elongated holes by covering the elongated holes on the outer reference circle of the one ring with an addi-tional ring provided with bores corresponding to the hole spacing and the diameter of the bores on the outer reference circle of the other ring of the adapter.
The invention, which can be used both for single-phase and multi-phase enclosed installations and tubular conductors, will be described in greater detail herebelow on the basis of the exemplary embodiments illustrated in Figures 1 to 6 of the draw-ings.

In a single-phase metal-enclosed high-voltage power sta-tion insulated with SF6 pressurized gas the conductors 2, accom-modated in three housings 1 arranged closely together (see Figure 1), belonging to a field circuit of a switchboard section of the high-voltage power station and running parallel to each other in the direction of the longitudinal axes 3 of the housings 1 indi-; cated by dot-dash lines, are connected to open-wire circuit con-nections that are not illustrated and which are a substantially greater distance apart.

The other ring 20 is fastened to the flange 10 by screws 28 which are ~crewed into the threaded bores 22 and whose head 29 is supported on the outer end face 30 of the flange 10.

To achieve the angular adjustability of the connection between two housings 1 and 7 in accordance with any angle + ~ be-tween the longitudinal axes 3 and 6 which should lie between 0 to 90, the following conditions on the two-part adapter 8 are adher-ed to:
A hole spacing ~a2~ which can be added up to 360 or 180, is selected on the ring 20 whose bores 32 on the outer ref-erence circle 31 are designed as elongated holes 32. The length of the elongated holes 32 then corresponds to half the hole spac-ing ~a2. On the other ring 19 of the adapter 8 a hole spacing is selected for the bores 33 on the outer reference circle 31 which corresponds to half the hole spacing ~a2 of the elongat-ed holes 32 of the other ring 20. This selection must naturally be made in such a way that the distances between the individual bores 33 are sufficiently small in order to guarantee the gas tightness if only every second bore 33 is covered with the fasten-er 34.
On account of this relationship both between the length of the elongated ho1es 32 and between the hole spacings ~a2 f the elongated holes and the hole spacing ~a2/2 of the bores 33 on the other ring 19, complete displaceability of each elongat-ed hole 32 over an area of at least one hole spacing of the bores 33 is given. In this area one bore 33 is thus always covered with the elongated hole 32 (see Figure 4). Thus, the hole spacing ~i on the inner reference circles 21 of the rings 19, 20 can be se-lected completely freely, whereby only the gas tightness must be taken into consideration. This hole spacing ~i of the bores 23 and 22 corresponds then to the hole spacings ~16 on the :, '.. ~' : ~ ' , , . -: t~ ' . ' : .

The ~ame applies for ring 20 which is fastenea to the flange 10 with the screw 28.
If the rings 19, 20 are placed ~o that they abut one another, then it can be seen that even on the outer reference circles 31 of the rings 19, 20 at least one bore 33 iY in alignment with the elon-gated hole 32 ~o that despite the existing angle ~ between the longitudinal axes 3, 6 of the housing~ 1, 7 the two rings 19, 20 can be connected to each other without difficulty with the aid of the bolt 34.
A further modified exemplary embodiment is illustrated in Figures 5 and 6, whereby the same reference numerals were re-tained for the same parts.

A hole spacing ~a2~ which can be added up to 360 or 180, is selected on the ring 20 whose bores 32 on the outer ref-erence circle 31 are designed as elongated holes 32. The length of the elongated holes 32 then corresponds to half the hole spac-ing ~a2. On the other ring 19 of the adapter 8 a hole spacing is selected for the bores 33 on the outer reference circle 31 which corresponds to half the hole spacing ~a2 of the elongat-ed holes 32 of the other ring 20. This selection must naturally be made in such a way that the distances between the individual bores 33 are sufficiently small in order to guarantee the gas tightness if only every second bore 33 is covered with the fasten-er 34.
On account of this relationship both between the length of the elongated ho1es 32 and between the hole spacings ~a2 f the elongated holes and the hole spacing ~a2/2 of the bores 33 on the other ring 19, complete displaceability of each elongat-ed hole 32 over an area of at least one hole spacing of the bores 33 is given. In this area one bore 33 is thus always covered with the elongated hole 32 (see Figure 4). Thus, the hole spacing ~i on the inner reference circles 21 of the rings 19, 20 can be se-lected completely freely, whereby only the gas tightness must be taken into consideration. This hole spacing ~i of the bores 23 and 22 corresponds then to the hole spacings ~16 on the :, '.. ~' : ~ ' , , . -: t~ ' . ' : .
