Arrangement for the bays of transformer stations, Switching stations and the like against pressure waves occurring in their interior

Priority of the Hanover Fair 1973

The present innovation has an arrangement for the protection of % transformer stations, switching stations and the like against pressure waves arising or occurring in their interior.

The known arrangements for protection against pressure waves consist mostly of ventilation openings with covers, which are located when If a pressure wave occurs, open and release the ventilation openings. Most of these covers are flaps that surround a Swing out the horizontal axis, or blinds. Similar to explosion flaps on media lines, they have the purpose of to prevent the lines or the connected structure from being destroyed when pressure waves occur.

The known arrangements for protection against pressure waves are additional devices on the structures and the like and usually very expensive.

The present innovation has the task of an arrangement for Protection of transformer stations, switching stations and the like to create one or more vents the transformer station and the like covering covers that open when a pressure wave occurs and

release the vents, exists and which can be achieved without great effort.

The object is achieved according to the innovation in that the cover the ventilation opening as a roof d <jr transformer station is formed and its attachment to the support part of the roof of the transformer station is designed as a pressure wave protection and for this purpose consists of a series of plastic screws connecting the supporting part of the roof and the roof, which in the overall cross-section are dimensioned as a pressure wave protection, and also from a number of anchored in the roof and through the support part long steel screw bolts passing through the roof with play with adjustable nuts on their free ends, which together serve as a holder and path limitation of the roof that lifts off the supporting part when pressure waves occur.

A particularly advantageous solution for the support part is that it consists of an angle iron or the like that runs along the inside of the enclosing walls of the transformer station and the like , to be fastened to them, and of an angle set on its horizontal leg, on whose vertical legs the roof is below With the aid of a recess in the roof is placed and the plastic screws and the screw bolts pass through the two horizontal legs.

The solution according to the innovation, since a support part and fastening elements are usually available for the roof of the transformer station and the like , the advantage that almost no additional elements have to be present, but these only have to be adapted to the solution of the task. The effort is extremely low compared to the success of the innovation.

The drawing explains a section of the upper part a Transfonnatorenstation the inventive idea.

A circumferential angle iron 2 is attached to the circumferential inner side wall 1 of the station. On this angle iron 2 sit at intervals several Winkeleisenst-Ücke 3 or one as well all-round angle iron. They form the supporting part. The roof 5 is placed on the vertical legs 4 of the angle iron 3. So that its position is determined, it is equipped on the edge with a circumferential recess or several recesses 6, in which the legs 4 -er angle iron 3 engage. You firm The roof 5 and side walls 1 are connected by means of nuts Ö and plastic screws pressed into the web 7 of the roof 5 9 »which are passed through the horizontal legs of the angle irons 2 and 3«. This plastic st screw off 9 that at tear through a predetermined pressure, thus serve as a pressure wave protection. To prevent the roof 5 at a Blast wave is ejected, and around to. achieve that ^ it is only lifted and opens a ventilation gap, 5 screw bolts 10 made of steel are anchored in the web 7 of the roof, which through the horizontal legs of the angles 2 and 3 are stuck through with play. At the end nuts 11 are screwed on. With their help one can find the way of raising the Define or limit roof 5 and thus the size of the Entllungsspaltes determine.

Claims (1)

Protection claims 1. Arrangement for contactors of transformer stations, switching stations and the like against pressure waves occurring inside them, consisting of one or more vents openings of the transformer station and the like covering covers, which are when a Open pressure wave and release the ventilation openings, characterized in that the cover of the ventilation opening is designed as the roof of the transformer station and its attachment to the supporting part of the roof of the transformer station is designed as a pressure wave protection and for this purpose from a number of the supporting part of the roof and the roof connecting plastic screws consists in the total cross-section are dimensioned as a pressure wave protection, and also from a number of anchored in the roof and through the support part the roof with play through long screw bolts made of steel with adjustable on their free ends Nuts, which together act as a holder and limit the path of the lift off the support part when pressure waves occur Serve the roof. 2 · Arrangement for contactors of transformer stations, switching stations and the like against pressure waves according to claim, characterized in that the support part for the roof is made of one along the inside of the transformer station's primary wall and the like circumferential to them to be fastened angle iron or the like and on its horizontal Legs are placed angles, on the vertical legs of which the roof with the aid of a recess is placed in the roof and through the two horizontal legs of the plastic screws and the screw bolts go through.
