FIGURBESKRIVNIN G Uppfinningen beskrives närmare nedan under hänvisning till bifogade ritning på vilken den enda figuren visar en utföringsforrn av en strörnförsörjningsenhet med en anordning enligt uppfinningen.DESCRIPTION OF THE FIGURES The invention is described in more detail below with reference to the accompanying drawing, in which the only figure shows an embodiment of a power supply unit with a device according to the invention.
BESKRIVNING AV UPPFINNINGEN På ritningen betecknar 1 en strömskena i en strömförsörjningsenhet. Det bör nämnas att skenan 1 antages ha negativ potential i den visade utföringsformen.DESCRIPTION OF THE INVENTION In the drawing, 1 denotes a busbar in a power supply unit. It should be mentioned that the rail 1 is assumed to have negative potential in the embodiment shown.
I den visade utföringsforrnen är två likriktare 2 anslutna med sina utgångsklärrnnor till skenan 1. Det torde inses att det alternativt kan finnas endast en likriktare eller fler än två likriktare. Likriktarnas 2 ingångsklämmor är hopkopplade till en klämma 3 till vilken växelström matas från exempelvis ett nät eller en växelströrns generator (icke visad).In the embodiment shown, two rectifiers 2 are connected with their output terminals to the rail 1. It should be understood that there may alternatively be only one rectifier or more than two rectifiers. The input terminals of the rectifiers 2 are connected to a terminal 3 to which alternating current is supplied from, for example, a network or an alternating current generator (not shown).
För att strömmata skenan 1 vid ett växelströmsbortfall förefinnes två batterier 4 i den visade utföringsformen. Det torde inses att det altemativt kan finnas endast ett batteri eller fler än två batterier.In order to supply power to the rail 1 in the event of an AC failure, there are two batteries 4 in the embodiment shown. It will be appreciated that alternatively there may be only one battery or more than two batteries.
Skenan 1 antages strömmata två laster 5 och 6 i den visade utföringsforrnen.The rail 1 is assumed to carry two loads 5 and 6 in the embodiment shown.
Lasten 5 antages vara en oprioriterad last som via säkringar (icke visade) är ansluten till skenan 1. Den oprioriterade lasten 5 kan innehålla kapacitanser.The load 5 is assumed to be a non-prioritized load which is connected to the rail 1 via fuses (not shown). The non-prioritized load 5 may contain capacitances.
Lasten 6 antages vara en prioriterad, kapacitansinnehållande last. 10 15 20 25 30 i 516 394 fr. -: 3 Med prioriterad last menas en last som är viktigare, dvs viktigare att strömförsörja, än en oprioriterad last såsom exempelvis lasten 5.Load 6 is assumed to be a priority, capacitance-containing load. 10 15 20 25 30 i 516 394 fr. -: 3 Priority load means a load that is more important, ie more important to supply power, than a non-priority load such as the load 5.
Enligt uppfinningen är den prioriterade lasten 6 ansluten till skenan 1 via säkringar (icke visade) och å ena sidan en diod Dl och å andra sidan en kontaktor 8, dioder D2 och en kontaktor 7.According to the invention, the prioritized load 6 is connected to the rail 1 via fuses (not shown) and on the one hand a diode D1 and on the other hand a contactor 8, diodes D2 and a contactor 7.
Det torde inses att det kan finnas ett antal prioriterade laster (icke visade) med olika prioriteter. I ett dylikt fall skulle varje prioriterad last vara ansluten till skenan 1 via respektive dioder motsvarande dioden D1 samt till hopkopplingspunkten mellan batterierna 4 och kontaktom 7 via respektive dioder och kontaktorer motsvarande diodema D2 och kontaktom 8.It will be appreciated that there may be a number of priority loads (not shown) with different priorities. In such a case, each priority load would be connected to the rail 1 via the respective diodes corresponding to the diode D1 and to the connection point between the batteries 4 and the contactor 7 via the respective diodes and contactors corresponding to the diodes D2 and the contactor 8.
För att utsträcka den tid som den prioriterade lasten 6 kan strömmatas från batteriema 4 vid ett växelströmsbortfall, dvs när skenan l strömmatas från batteriema 4, styrs den mellan batteriema 4 och skenan 1 inkopplade kontaktom 7 medelst en styrenhet (icke visad) till att brytas i och för att koppla bort den oprioriterade lasten 5 från batteriema 4 när batteriema 4 urladdats i enlighet med en första parameter, vilket detekteras medelst styrenheten (icke visad).In order to extend the time that the prioritized load 6 can be energized from the batteries 4 in the event of an AC failure, ie when the rail 1 is energized from the batteries 4, the contact 7 connected between the batteries 4 and the rail 1 is controlled by means of a control unit (not shown) to be broken. and for disconnecting the unprioritised load 5 from the batteries 4 when the batteries 4 have been discharged according to a first parameter, which is detected by the control unit (not shown).
Denna första parameter kan exempelvis vara den tid som förflutit sedan växelströmsbortfallet inträffade, den spänning till vilken batteriema 4 urladdats sedan växelströmsbortfallet inträffade, den energi som förbrukats sedan växelströmsbortfallet inträffade eller den intäkt som genererats sedan växelströmsbortfallet inträffade eller kombinationer av dessa.This first parameter can be, for example, the time elapsed since the AC failure occurred, the voltage to which the batteries 4 were discharged since the AC failure occurred, the energy consumed since the AC failure occurred or the revenue generated since the AC failure or combinations occurred.
För att enligt uppfinningen förhindra skador på batteriema 4 efter ett växelströmsbortfall styrs kontaktom 8 av styrenheten (icke visad) till att brytas efter det att kontaktom 7 brutits när batteriema 4 urladdats ytterligare i enlighet med en 10 15 20 25 30 f51_6 394 4 andra parameter, vilket detekteras medelst styrenheten (icke visad). Denna andra parameter kan exempelvis var tiden, spänningen eller energin eller kombinationer av dessa på ovannärrmt sätt.According to the invention, in order to prevent damage to the batteries 4 after an AC failure, the contactor 8 is controlled by the control unit (not shown) to be broken after the contactor 7 is broken when the batteries 4 are further discharged in accordance with a second parameter. which is detected by the control unit (not shown). This second parameter can be, for example, the time, voltage or energy or combinations of these in an above-mentioned manner.
Ifall det finns ett flertal kontaktorer motsvarande kontaktorn 8 skulle dessa kontaktorer styras till att brytas i enlighet med olika parametrar i beroende av respektive prioriterad lasts prioritet.If there are a plurality of contactors corresponding to the contactor 8, these contactors would be controlled to be broken in accordance with different parameters depending on the priority of the respective priority load.
När växelströmsbortfallet upphör och kontaktorerna 7 och 8 fortfarande är brutna, dvs i de i figuren visade lägena, leder dioden Dl ström från likriktarna 2 via skenan 1 till lasten 6, medan lasten 5 strömmatas direkt från skenan 1.When the AC failure ceases and the contactors 7 and 8 are still broken, i.e. in the positions shown in the figure, the diode D1 conducts current from the rectifiers 2 via the rail 1 to the load 6, while the load 5 is supplied directly from the rail 1.
Efter det att växelströmsbortfallet upphört, styrs kontaktorn 7 till slutning medelst styrenheten (icke visad) när ett första villkor är uppfyllt, t ex att skenan 1 är spänningssatt och att en förutbestämd tid förflutit, vilket detekteras medelst styrenheten (icke visad).After the AC failure has ceased, the contactor 7 is finally controlled by the control unit (not shown) when a first condition is met, for example that the rail 1 is energized and that a predetermined time has elapsed, which is detected by the control unit (not shown).
Härigenom matas ström till batterierna 4 från likriktarna 2 via skenan 1 och den slutna kontaktorn 7 i och för att återuppladda batterierna 4.As a result, current is supplied to the batteries 4 from the rectifiers 2 via the rail 1 and the closed contactor 7 in order to recharge the batteries 4.
Kontaktorn 8 styrs till slutning medelst styrenheten (icke visad) efter det att kontaktorn 7 slutits, när ett av styrenheten (icke visad) detekterat, andra villkor uppfyllts, tex att skenan l är spänningssatt och att en förutbestämd tid förflutit sedan slutningen av kontaktorn 7.The contactor 8 is finally controlled by means of the control unit (not shown) after the contactor 7 has been closed, when one of the control units (not shown) is detected, other conditions are met, eg that the rail 1 is energized and that a predetermined time has elapsed since the closing of the contactor 7.
Om flera kontaktorer motsvarande kontaktorn 8 förefinnes kommer samtliga dessa att styras till slutning.If kontakt your contactors corresponding to the contactor 8 are present, all of these will be controlled at the end.
Härigenom matas ström till den kapacitansinnehållande lasten 6 från likriktama 2 via dioden Dl och/eller via skenan 1 och de slutna kontaktorerna 7 och 8. . '516 394 i” 5 De mellan kontaktorn 8 och respektive batteri 4 inkopplade dioderna D2 används för att förhindra laddning av batterierna 4 via kontaktom 8 om kontaktorn 8 av misstag skulle slutas före kontaktom 7.As a result, current is supplied to the capacitance-containing load 6 from the rectifiers 2 via the diode D1 and / or via the rail 1 and the closed contactors 7 and 8. '516 394 i' 5 The diodes D2 connected between the contactor 8 and the respective battery 4 are used to prevent charging of the batteries 4 via the contactor 8 if the contactor 8 were accidentally closed before the contactor 7.
Med anordningen enligt uppfinningen föreligger ingen risk för att batterierna 4 och kontaktom 8 skall skadas när växelströmsbortfallet upphör såsom torde framgå av det ovanstående.With the device according to the invention there is no risk that the batteries 4 and the contactor 8 will be damaged when the AC failure ceases as should be apparent from the above.
