Description
Bei einem biekannft'en Schwallwassenschutz für elektrische Maschinen sind die Öffnungen des Maschinengehäuses nuit einem voirstehenden Kragen versehen, der unter Belassung einlos Lüftzwlischienraumies durch eineu haubenartigen T.e(il üb!erdecU wird: Dieser Schwallwasserschutz verhübeit zwar das unmittelbare Eindringen von Wasser ins Gehäuse; eis läßt sich aber mituüber hi@chit vermeiden, daß an der Haube entlang lhufende Tropfen sich ablösen und beim Aufprallen auf dlüe gegenüberliegende Kragenwand sich ins [email protected] stäuben-: Bei einer anderen bekannten Anordnung ist die Schwallwasserschutzvorlrichtung : mit einem feirmaschigien Gitter überspannt; dieses wird also von den Wasserstrahlen direkt beaufschlagt und hat die Aufgabe, die Wucht dieser Wasseretrahlen vor dem Elintmiit in die Schutzvorrichtung abzuschwächen. Einren sicheren Schutz gegen Schwellwasser kann auch diese Vorrichtung nichtt btiteten, da hierbei Wasser durch Adhäsionskräfte an die Innenseite der Vorrichtung zu gelangen vermag und durch die in die Maschine eiinfiretende Luftströmung leicht in das Maschineninnere mitgerissen, ,werden kann.With a possible splash water protection for electrical machines the openings of the machine housing are provided with a protruding collar, which, while leaving a single ventilation space, is created by a hood-like T.e (il over! erdecU: This splash water protection prevents direct penetration of water into the housing; ice can be avoided with hi @ chit that on the Drops running along the hood are detached and when hitting the opposite one Collar wall dusting itself into [email protected]: In another known arrangement is the surge protection device: covered with a feirmaschigien grille; this is therefore directly impacted by the water jets and has the task of to weaken the force of these water jets in front of the Elintmiit in the protective device. Even this device cannot provide reliable protection against swell water, as this causes water to reach the inside of the device through adhesive forces is able and easily into the interior of the machine due to the air flow flowing into the machine carried away,, can be.
Die Erfindung vermeidet diesen Mangel. E.rfindun@gsgiemäß. sind die durch einen haubenartigem Teil überdeckten Öffnungen des Maschinengehäuses miit dem Gitter odeir miit mehreren, insbesondere mit feinmaschigen Giietern überspannt. Infolge der Anordnung des. Gitters. an der Öffnung des Gehäuses, also :in diesem Falle auf der Innenseü'tz der Schutzvorriiichtung, .ist; eine dixekte Beaufschlagung des- Gitters dumch die Wasserstrahlen überhaupt nicht möglich; vielmehr werden die, am Kragen der Maschinenöffnung sich niederschlagenden Tropfen, die durch die Umlenkung der Wasserstrahlen in den Luftkanälen der Vorrichtung ihre kinetische Energie berelits verloren haben, durch .das Git)tler mit Sicherheit nach unten abgeleitet. Sogar größere Wasisermengen werden durch dies Gitter von der Gehäuseöffnung hinweggeleitet. In der Zeichnung :isst ein) Ausführungsbeispiel fwr die Eirfindung dargestellt. Hier ist z das Maschinengehäuse mit dein Öffnung 2.The invention avoids this deficiency. E.rfindun@gsgiemäß. are the Openings in the machine housing covered by a hood-like part with the lattice or with several, especially fine-meshed girders. As a result of the arrangement of the grid. at the opening of the housing, so: in this Trap on the inside of the protective device, .is; a dixect charge of the grid by the water jets not possible at all; rather they will drops precipitating on the collar of the machine opening, caused by the deflection the water jets in the air ducts of the device berelits their kinetic energy have lost, by .the grid with certainty diverted downwards. Even larger amounts of washer are conducted away from the housing opening through this grille. In the drawing: is an) embodiment for the Eirfindung shown. Here is the machine case with your opening 2.
Rings um diese Öffnung verläuft ein Kragten 3, der von seinem haubenartigen T'eil4 unter Belassung eines. Luftzwise'henraurnes 5 überdeckt wird: Über den Kragenrand isst ein feinmaschiges Netz 6 mit einer Maschenweite vorn etwa i bis 2 min gespannt; doch kann auch eirn Gitter mit größerer Maschenweite verwendet werden. Ist das, Gitter engmaschig, dann bilden die Gittermaschen bei Benetzeng Flüssigkeitshäutchen, die wie eine Wand das Wasser ableiten,. Ist die Maschenweite des Gitters, größer, dann läufst das Wasser an den Gitterstäben entlang. Bei weitmaschigen, Gittern wird man durch entsprechende Formgebung des oberen Kragenteils dafür sargen, daß das Wasser durch schräg nach abwärts gerichtete Drähte, Bleche od. dgl. den Gitterstäben zugeführt wird und nicht zwischen diesen Drähten Tropfion bilden kann.Around this opening a collar 3 extends from its hood-like Part4 leaving one. Luftzwise'henraurnes 5 is covered: Over the edge of the collar eats a fine-meshed net 6 with a mesh size at the front stretched for about 1 to 2 minutes; however, a grid with a larger mesh size can also be used. Is this, Close-meshed lattice, then the lattice meshes form small membranes of liquid when wetted, which drain the water like a wall. If the mesh size of the grid is bigger, then the water runs along the bars. In the case of wide-meshed, lattice will you coffin by appropriate shaping of the upper part of the collar that the Water through diagonally downwardly directed wires, sheets or the like. The bars and cannot form a drip between these wires.
Auch empfiehlt es siith, durch eine Abwärtsneigung des unteren Kragenteils den Wasserablauf vom Gitter nach. außen zu unterstützen.It is also advisable to tilt the lower part of the collar downwards the water drainage from the grid. support outside.
