Description
Gebiet der ErfindungField of invention
Die Erfindung betrifft das Abkühlen einer unerwünscht erhöhten Temperatur oder das Unterdrücken einer Flammenverbrennung in geschützten elektrischen Einrichtungen, z.B. in Klimaanlagen und Lüftungsgeräten, Gasanschlüssen, Umspannstationen und Schalttafeln, in Computerboxen, in Servern, in Telefonvermittlungen und ähnlichem. In diesen geschützten elektrischen Einrichtungen können unerwünschte thermische Erscheinungen auftreten, deren negative Auswirkungen zu einem allmählichen Verlust der Funktionalität oder zur Zerstörung dieser Einrichtungen führen können und in äußersten Fällen sogar zur Flammenverbrennung führen können. Dies kann durch verschiedene Prozesse wie z.B. unerwünschte chemische Reaktionen, elektrische Kurzschlüsse, Überhitzung des Systems, Lichtbögen, Entflammung von Betriebsfluiden usw. verursacht werden.The invention relates to cooling an undesirably elevated temperature or suppressing flame combustion in protected electrical equipment, e.g. in air conditioning and ventilation devices, gas connections, substations and switchboards, in computer boxes, in servers, in telephone exchanges and the like. Undesirable thermal phenomena can occur in these protected electrical devices, the negative effects of which can lead to a gradual loss of functionality or destruction of these devices and, in extreme cases, even to flame combustion. This can be caused by various processes such as undesirable chemical reactions, electrical short circuits, overheating of the system, arcing, ignition of operating fluids, etc.
Hintergrund der ErfindungBackground of the invention
Um in geschützten elektrischen Einrichtungen die unerwünschte Temperaturzunahme zu verringern oder die Flammenverbrennung zu unterdrücken, sind Niederdruckvorrichtungen geeignet. Es gibt automatische Niederdruckvorrichtungen zum Abkühlen der unerwünscht zunehmenden Temperatur oder zum Unterdrücken einer Flammenverbrennung in geschützten Einrichtungen, die einen Kühlmediumträger umfassen, dessen Aktivierung auf dem Platzen des Kühlmediumträgers wegen der unerwünscht zunehmenden Temperatur oder einer Flammenverbrennung, die in einer geschützten Einrichtung entstanden ist, beruht. Für diese Einrichtungen kann die Temperatur, bei der der Kühlmediumträger gebrochen wird, nicht einfach gesteuert werden, um das Freisetzen des Mediums in die geschützte Einrichtung zu verhindern.In order to reduce the undesirable increase in temperature or to suppress flame combustion in protected electrical equipment, low-pressure devices are suitable. There are automatic low pressure devices for cooling the undesirably increasing temperature or for suppressing flame combustion in protected facilities, which include a cooling medium carrier, the activation of which is based on the rupture of the cooling medium carrier due to the undesirably increasing temperature or a flame combustion created in a protected device. For these devices, the temperature at which the cooling medium carrier is broken cannot be easily controlled to prevent release of the medium into the protected device.
Kurzfassung der ErfindungSummary of the invention
Der oben erwähnte Nachteil wird beseitigt und das Gebiet der Schutzausrüstung wird ergänzt durch eine Niederdruckvorrichtung zum Verringern der unerwünscht erhöhten Temperatur oder zum Unterdrücken der Flammenverbrennung in geschützten elektrischen Einrichtungen, die in dieser geschützten elektrischen Einrichtung angeordnet ist und aus einem Träger besteht/einen Träger aufweist, innerhalb dessen ein komprimiertes Kühlmedium vorhanden ist; der Träger ist ferner mit einem Füllventil versehen, um das Kühlmedium in den Träger einzufüllen; darüber hinaus ist der Träger mit einem Druckmesser zur passiven Orientierungssteuerung des Kühlmediums und mit einem Drucksensor zum Trennen der geschützten elektrischen Einrichtung von der elektrischen Versorgung und zum Verbinden mit einer Signalisierungsausrüstung, falls innerhalb der geschützten Einrichtung eine unerwünscht erhöhte Temperatur detektiert wird, versehen, wobei die Erfindung ferner vorsieht, dass der Träger aus Kunststoff oder Metall oder einer Metallzusammensetzung in irgendeiner hohlen geschlossenen Form und Größe hergestellt ist, wobei der Träger ferner mit zumindest einem Temperaturdetektor, z. B. einer Ampulle aus temperaturwechselbeständigem Glas, versehen ist. Die Ampulle aus gegen Temperaturwechsel beständigem Glas ist durch eines von mehreren Verfahren in dem Träger angebracht, wobei sie z. B. in die Trägerkapselöffnung geschraubt, geklebt, gelötet usw. ist. Sobald die Temperatur in dem Bereich einer geschützten elektrischen Einrichtung, wo eine Niederdruckvorrichtung angeordnet ist, auf einen bestimmten unerwünschten Wert zunimmt, bricht die Glasampulle, erzeugt in dem Träger eine Öffnung, durch die das Kühlmedium in den Bereich der geschützten elektrischen Einrichtung freigesetzt wird, und kühlt die unerwünscht erhöhte Temperatur ab oder unterdrückt die Flammenverbrennung.The above-mentioned disadvantage is eliminated and the field of protective equipment is supplemented by a low-pressure device for reducing the undesirably elevated temperature or for suppressing flame combustion in protected electrical equipment, which is arranged in this protected electrical equipment and consists of/has a support, within which a compressed cooling medium is present; the carrier is further provided with a filling valve for filling the cooling medium into the carrier; In addition, the carrier is provided with a pressure gauge for passive orientation control of the cooling medium and with a pressure sensor for disconnecting the protected electrical device from the electrical supply and for connecting to signaling equipment if an undesirably increased temperature is detected within the protected device, the The invention further provides that the carrier is made of plastic or metal or a metal composition in any hollow closed shape and size, the carrier further being equipped with at least one temperature detector, e.g. B. an ampoule made of glass that is resistant to temperature changes. The ampoule of thermally resistant glass is attached to the carrier by one of several methods, e.g. B. screwed, glued, soldered, etc. into the carrier capsule opening. As soon as the temperature in the area of a protected electrical device where a low pressure device is arranged increases to a certain undesirable value, the glass ampoule ruptures, creating an opening in the carrier through which the cooling medium is released into the area of the protected electrical device, and cools down the undesirably elevated temperature or suppresses flame combustion.
Für einige Ausrüstungstypen ist der Kühlmediumträger mit einer Dichtverbindung versehen.For some types of equipment, the coolant carrier is provided with a sealing connection.
Die Aktivierungstemperatur der Vorrichtung, bei der die Glasampulle wegen der unerwünscht erhöhten Temperatur bricht und in dem Träger eine Öffnung erzeugt, durch die das Kühlmedium in die geschützte elektrische Einrichtung freigesetzt wird, ist bevorzugt 50 °C. Glasampullen werden aus Glas mit verschiedenen Zusammensetzungen hergestellt, die bei unterschiedlichen Temperaturen in dem Bereich von 50 °C bis 260 °C brechen.The activation temperature of the device, at which the glass ampoule breaks due to the undesirably elevated temperature and creates an opening in the carrier through which the cooling medium is released into the protected electrical device, is preferably 50 ° C. Glass ampoules are made from glass with different compositions that break at different temperatures ranging from 50°C to 260°C.
Die Temperatur, bei der die Ampulle aus temperaturwechselbeständigem Glas bricht, kann durch Verwendung von Ampullen mit verschiedenen Glaszusammensetzungen eingestellt werden, sodass die Niederdruckvorrichtungsaktivierung in Übereinstimmung mit den Bedingungen und Annahmen des Auftretens der unerwünscht erhöhten Temperatur gesteuert werden kann.The temperature at which the thermal shock resistant glass ampoule ruptures can be adjusted by using ampoules with different glass compositions so that the low pressure device activation can be controlled in accordance with the conditions and assumptions of occurrence of the undesirably elevated temperature.
