Abstract
A metal-enclosed medium voltage switch gear panel (1) has a switching compartment (2), a bus bar compartment(4), and a cable connecting compartment (10). The bus bar compartment(4) and the cable connecting compartment (10) are arranged in a first housing (31), whereas a front frame for holding a door (7) of the switching compartment (2) and at least part of the switching compartment (2) are integral parts of a second housing (32). A third housing (45) is optionally arranged between the first housing (31) and the second housing (32) in order to create a compartmented type switch gear panel, in which a bulkhead provided with passages for disconnecting contacts is arranged between the switching compartment (2) and the other two compartments (4, 10).
Description
-Metal-Enclosed Medium-Voltage Switch Gear Panel with Switching Compartment, Bus Bar Compartment, and Cable Connecting Compartment The present invention relates to a metal-enclosed medium-voltage switch gear panel with a switching compartment for a power switch and with a bus bar compartment that is located in a rear part of the switch panel and a cable connecting compartment and a low voltage compartment and front doors for the switch gear panel and the low voltage compartment arranged above the switching compartment.
.
Examples of medium-voltage switch panels are described, for example, in the German company brochure entitled Seimens:
Mittelspannung-Leistungsschalteranlagen Programmubersicht [Siemens: Medium-voltage Power Switch Systems Programme Overview], Order Number E 50001-U 229-Al, release date April 1991. A distinction must be made between switching systems of this kind, the panels of which are separated from each other by bulkheads that are of sheet steel, and switching systems in which such separation is not made, or is made only in part. In the case of completely compartmented switch panels, the bus bar compartment, the cable connecting compartment, and the switching compartment are separated from each other by the bulkheads referred to above, whereas in the case of non-compartmented or partially compartmented switch panels, these compartments are to be regarded as a functional division of a total space.
EP-A-0 459 593 describes how identical housing sections can be provided in order to ensure the functional division of switchgear panels when these are combined in the manner of modules. However, when this is done, it is impossible to 21 60~24 -provide the differing structural forms for compartmented and non-compartmented switchgear panels since the functional association cannot be realized as a function of space.
EP-A-O 144 753 describes a switch gear panel in which the functional units are completely separated. No reference is made to problems with respect to non-compartmented or partially compartmented switch panels.
The various embodiments of the switch panels discussed above are selected on the basis of the particular requirements. When this is done, the especially high level of safety achieved when the interior space is divided by sheet-steel bulkheads is compared to the smaller depth and thus the smaller space requirements for switch panels with non-compartmented or partially compartmented embodiments. Since it has been shown that both methods of constructing switch panels are used in practice, it is thus necessary to have the necessary tools and apparatuses on hand for making both types. This results in a not-inconsiderable outlay.
It is the task of the present invention to simplify the selective manufacture of both types of medium-voltage switch gear panels and thus lower the associated costs.
According to the present invention, this task has been solved in that the cable connecting compartment and the bus bar compartment are accommodated in a first housing section that is open to the front; a front frame for securing the door system of the switch compartment and at least a part of the switching compartment are components of a second housing section that is open to the rear, and the first and the second housing sections are of identical width and incorporate frame elements that can be connected to each other.
The structure for a switch panel of the non-compartmented type can now be manufactured in that a first and a second housing section are connected directly to each other. However, the same housing sections can be used for a switch panel of the compartmented type if, according to one embodiment of the present invention, a third housing section is inserted between the first and the second housing sections; the depth of this third housing section is such as to correspond to the space required for a bulkhead that separates the switching compartment from the cable connecting compartment and the bus bar compartment and passages for breaker contacts. Only this third housing section, i.e., a part that is of relatively small volume, need be manufactured in order to permit production of a switch panel of the compartmented type by using first and second housing sections that are, in any case, on hand.
In order to simplify assembly of the housing section, it is recommended that the second housing section has on its back a connecting frame that can be installed on the first or third housing section, respectively.
In addition, it is also advantageous with respect to assembling the housing sections if the first housing section incorporates a base panel with profiled edges on the sides, a section of the base panel extending beyond the front frame;
and in that the second housing section can be mounted on the projecting section of the base panel and joined to this section.
According to another configuration of the present invention, the third housing section, too, can be aligned with the other housing sections in that the third housing section has a base panel with profiled edge sections; and in that a portal that is mounted on the base panel dividesthe base panel into a rear 21 60~24 section and a front section, the foremost section matching the length and shape of the base panel section of the first housing section.
Work-protection panels have been developed to ensure safety when working with switch panels that are not compartmented, and these separate the bus bar compartment from the switching compartment on a temporary basis. Work protection panels of this kind can also be used in switch panels according to the present invention if the front frame of the second housing section has a slot-like opening that is located above the door opening and can be used to install a work protection panel.
The present invention will be described in greater detail below on basis of the drawings appended hereto.

switch gear panels according to the present invention is explained on the basis of Figure 3 and Figure 4. The switch gear panel 1 that is shown in Figure 1 incorporates a switching compartment 2 within which a vacuum power switch 3 is shown as an example of a switch gear. Within the upper rear area of the switch gear panel 1 there is a bus bar compartment 4 with bus bars 5. Breaker contact systems make it possible to move the power switch 3 from the operating position that is shown into a break position with the door 7 closed. Within the lower rear area of the switch gear panel 1 there is a cable connecting compartment 10, into which cable 11 is introduced from below. In the example that is shown, this is connected through a current transformer 12 to the breaker contact system 6 on the output side. An output ground 13 and a voltage converter 14 are shown as additional components. In addition, the insertion of a work protection panel 15 is indicated by a dashed line between the switching compartment 2 and the bus bar compartment 4. Above the front part of the switching compartment 2 there is a low-voltage compartment 16 that accommodates display, warning, and operating systems.
As can be seen from Figure 1, the switching compartment 2, the bus bar compartment 4, and the cable connecting compartment 10 are simply areas of a total space within the switch gear panel 1 and are not compartmented. For this reason, this arrangement is referred to as a non-compartmented switch gear panel.
The components referred to in connection with Figure 1 are also used in the switch gear panel 2 that is shown in Figure 2, where they bear the same reference numbers; in Figure 2, however, the switching compartment 2, the bus bar compartment 4, and the cable connecting compartment 10 are separated from each other by bulkheads. To this end, a bulkhead 21 that extends to the whole height of the switch gear panel 20, and `_ an additional bulkhead 22 that separates the bus bar compartment from the cable connecting compartment 10 are used.
Upper passages 23 and lower passages 24 are provided in the bulkhead 21 to accommodate the breaker contact systems. The bulkheads 21 and 22 ensure that any arcing that occurs in the compartment 2, 4, and 10 is confined to the compartment in which it occurs, so that the remaining compartments are not affected. As can be seen, however, a construction that incorporates bulkheads means that the switch gear panel 20 must be deeper than the switch gear panel 1 that is shown in Figure 1.
The manner in which the housing for the switch gear panel can be manufactured by using identical housing sections, despite different installed depths, will be described below.
As is shown in Figure 3, a switch gear panel of the non-compartmented type, as is shown in Figure 1, is to be installed in a housing 30 that can be assembled from a first housing section 31 and a second housing section 32. In Figure 3, the housing sections 31 and 32 are shown separated from each other, although for purposes of clarity the overall dimensions are indicated by dashed lines. The housing section 31 consists in part of solid wall sections and in part of framework or frame elements. These parts form two side frames 33 and a front frame 34 beyond which a section 36 of the base panel 35 extends at the front. The base panel 35 has profiled edges 37. The second housing section 32 has a front frame 38 for a door system, and an insertion slot 40, which is located above this, for a work protection panel. Above this there is a separate area that is used as a low-voltage compartment (compare the low-voltage compartment 16 that is shown in Figure 1 and Figure 2). The housing section 32 is of the same height as the housing section 31 and when assembled this is of a depth, as is shown in Figure 3 by dashed lines, with respect to the housing section 31, that results in a volume that is sufficient for a non-compartmented switch gear panel. The profiled edges 37 that extend beyond the front frame 34 simplify the precise assembly of the two housing sections 31 and 32 in that there is a matching recess 41 on the sides of the second housing section 32. This recess extends as far as the back of the front frame 38. The connection of the housing section 31 and 32 can be effected in such a manner that after the installation of the second housing section 32 on the edges 37, those of the front frame 34 of the housing section 31 are aligned with a rear frame 42 of the housing section 32 and fastened with a number of bolts or are joined by a continuous weld or by spot welds.
Figure 4 shows a third housing section 45 in addition to the housing section 31 and a housing section 32; this is of the same height and width as the housing sections 31 and 32.
Essentially, the housing section 45 consists of a base panel 46 with profiled edges 47, the shape of which corresponds to the edges 36 of the housing section 31. A portal 50 is mounted on the base panel 46 and this has a top panel and side walls.
The portal 50 divides the base panel 46 into a short rear section 51 and a longer section 52, the longer section 52 corresponding to the section 36 of the housing section 31. The rear section 51 is so ~imensioned that together with the section 36, the space between the first housing section 31 and the second housing section 32 is that which is necessary for a compartmented switch gear panel as is shown in Figure 2. A top panel 53 and side walls 54 of the third housing section 45 are connected with the first housing section 31. The front of the portal 50 matches the front frame 34 of the first housing section 31, so that the second housing section 32 can be connected as in the example that is shown in Figure 3. This results in a housing of greater structural strength and the volume that is required to construct a compartmented switch ,.
gear panel. A bulkhead with passages ~or breaker contacts can also be incorporated between thefirst housing section 31 and the third housing section 45 as a component of the same installed height.

As is shown in Figure 3, a switch gear panel of the non-compartmented type, as is shown in Figure 1, is to be installed in a housing 30 that can be assembled from a first housing section 31 and a second housing section 32. In Figure 3, the housing sections 31 and 32 are shown separated from each other, although for purposes of clarity the overall dimensions are indicated by dashed lines.
