Abstract
Description
25 30 35 526 326 2 Detta syfte uppnås enligt uppfinningen medelst en pumpstation vilken har de särdrag som anges i efter- följande patentkrav 1, med föredragna utföringsformer enligt underordnade patentkrav 2-10. This object is achieved according to the invention by means of a pump station which has the features stated in the following claim 1, with preferred embodiments according to subordinate claims 2-10.
Den nya pumpstationen är således försett med ett sensoraktiverat system vilket orsakar en felström som utlöser pumpstationsströmkällans jordfelsbrytare. Den genom uppfinningen åstadkomna pumpstationen är ytterst fördelaktig genom att den försätts i ett spänningslöst tillstånd på grund av att den externa strömtillförseln upphör när en eller flera sensorer känner av att pump- stationen öppnas, bryts upp eller genom annan form av åverkan blottläggs.The new pump station is thus equipped with a sensor-activated system which causes a fault current which triggers the earth fault circuit breaker of the pump station power source. The pumping station provided by the invention is extremely advantageous in that it is placed in a voltage-free state due to the fact that the external power supply ceases when one or more sensors sense that the pumping station is opened, broken up or exposed by some other form of damage.
I en föredragen utföringsform är det genom använd- ning av en kombination av flera ljus-, tryck-, magnet-, vibration-, spännings- rörelse- och/eller mekaniska sen- sorer mycket svårt att vid otillbörlig uppbrytning av pumpstationen undgå brytning av den externa strömtill- förseln.In a preferred embodiment, by using a combination of several light, pressure, magnetic, vibration, voltage motion and / or mechanical sensors, it is very difficult to avoid breaking the pump when the pump station is improperly broken. external power supply.
Varje pumpstation är lämpligen anordnad med en data- lagringsenhet som sparar information om och när den ex- terna strömtillförseln bryts, för att ytterligare för- svåra att otillbörligt användande passerar obemärkt.Each pumping station is suitably arranged with a data storage unit which saves information if and when the external power supply is interrupted, in order to further make it difficult for improper use to pass unnoticed.
I en variant av uppfinningen är det felströmsorsak- ande systemet försett med indikator för systemets fel- koppling, och i en annan variant är systemet försett med en indikator för indikering att systemet ej är påslaget.In a variant of the invention, the fault current causing system is provided with an indicator for the system's fault connection, and in another variant the system is provided with an indicator to indicate that the system is not switched on.
Båda dessa varianter underlättar korrekt utfört montage, efterutrustning och/eller service av pumpstationen.Both of these variants facilitate correctly performed assembly, retrofitting and / or service of the pump station.
Det felströmsorsakande systemet anordnas företrädes- vis internt i pumpstationen för enkel montering och ger genom sin konstruktion ett kostnadseffektivt skydd som även lätt kan eftermonteras på befintlig utrustning.The residual current-causing system is preferably arranged internally in the pump station for easy installation and, through its construction, provides cost-effective protection that can also be easily retrofitted to existing equipment.
Genom att lämpligen utrusta pumpstationen med en spänningsvakt detekteras spänningsbortfall vilket då medger att ett eller flera externa larm sätts igång och 10 15 20 25 30 35 526 326 3 eventuellt tillkallar säkerhetspersonal, servicepersonal etc.By suitably equipping the pump station with a voltage monitor, voltage loss is detected, which then allows one or more external alarms to be triggered and possibly call in security personnel, service personnel, etc.
En annan fördelaktig effekt av uppfinningen är att den även åstadkommer ett strömföringsskydd för t ex for- don som kör på pumpstationen eller för servicepersonal som glömmer att slå av spänningen. Genom uppfinningen kan svårligen pumpstationen deformeras eller öppnas utan att den externa strömtillförseln slås av.Another advantageous effect of the invention is that it also provides a current protection for, for example, vehicles driving at the pump station or for service personnel who forget to switch off the voltage. By means of the invention, the pump station can hardly be deformed or opened without the external power supply being switched off.
Kort beskrivning av ritningarna Uppfinningen kommer att beskrivas närmare i det följande under hänvisning till bifogad ritning som i exemplifierande syfte visar en för närvarande föredragen utföringsform av uppfinningen.Brief Description of the Drawings The invention will be described in more detail in the following with reference to the accompanying drawing which, by way of example, shows a presently preferred embodiment of the invention.
Fig l visar en schematisk bild av principen för uppfinningen.Fig. 1 shows a schematic view of the principle of the invention.
Beskrivning av föredragna utföringsformer Den i fig 1 visade pumpstationen l för bränslepà- fyllning av fordon är ansluten till en strömkälla 2 med jordfelsbrytare och innefattande minst en sensor 3 som detekterar någon form av åverkan på pumpstationen 1. Ex- empel på åverkan kan vara uppbrytning av eller borrning genom pumpstationens hölje, en brytning av kopplingen mellan pumpstationen och dess centrala enhet etc. En för- sta krets 4 är anordnad inuti pumpstationen 1 kopplad mellan en fasledare P och en skyddsjordledare PE och innefattar en strömbrytare 7 som kan vara t ex en mag- netisk och ett motstánd 8 kopplade i serie. Den första kretsen 4 är vanligtvis utformad att leda en ström (felström) större än 30mA.Description of Preferred Embodiments The pumping station 1 shown in Fig. 1 for refueling vehicles is connected to a power source 2 with an earth fault circuit breaker and comprising at least one sensor 3 which detects some form of damage to the pump station 1. An example of damage may be the breaking of or drilling through the pump station housing, a break in the connection between the pump station and its central unit, etc. A first circuit 4 is arranged inside the pump station 1 connected between a phase conductor P and a protective earth conductor PE and comprises a switch 7 which may be e.g. netic and a resistor 8 connected in series. The first circuit 4 is usually designed to conduct a current (fault current) greater than 30mA.
En andra krets 9 är kopplad mellan jord 10 och en spänningsenhet ll i pumpstationen 1 och innefattar kopplat i serie en strömbrytare 12 och ett relä 13 som styr slutning och öppning av strömbrytaren 7 i den första kretsen 4. Strömbrytaren 12 sluts medelst sensorn 3. I den föredragna utföringsformen parallellkopplas ström- brytaren 12 med andra strömbrytare vilka var för sig styrs av en kombination av andra sensorer, som till 10 15 20 25 30 35 526 326 4 exempel ljus-, tryck-, magnet-, vibration-, spännings- rörelse- och/eller mekaniska sensorer.A second circuit 9 is connected between ground 10 and a voltage unit 11 in the pump station 1 and comprises connected in series a switch 12 and a relay 13 which controls the closing and opening of the switch 7 in the first circuit 4. The switch 12 is closed by means of the sensor 3. I in the preferred embodiment, the switch 12 is connected in parallel with other switches which are each controlled by a combination of other sensors, which for example light, pressure, magnet, vibration, voltage movement and / or mechanical sensors.
Kopplad till sensorn 3 är en detektor 14 som detek- terar och på något känt sätt åstadkommer signal om sen- sorn 3 inte är aktiverad eller om den andra kretsen 9 inte är kopplad till spänningsenheten ll. Ett exempel på en effekt av en sådan àstadkommen signal är pumpstation- ens släckta displaybelysning. Anordnade inuti pumpsta- tionen är dels en datalagringsenhet 15 som lagrar data om när spänningsbortfall över pumpstationen sker, dels en spänningsvakt 16 som vid spänningsbortfall avger signal till t ex ett larm.Connected to the sensor 3 is a detector 14 which detects and in some known manner produces a signal if the sensor 3 is not activated or if the second circuit 9 is not connected to the voltage unit 11. An example of an effect of such a generated signal is the pump station's off display lighting. Arranged inside the pump station is partly a data storage unit 15 which stores data on when a voltage drop across the pump station occurs, and partly a voltage monitor 16 which in the event of a power failure emits a signal to, for example, an alarm.
Kopplat till den första kretsen 4 är en krets som känner av och med lysdiod indikerar om den första kretsen ej är korrekt monterad till strömkällans 2 ledare P och PE.Connected to the first circuit 4 is a circuit which detects and with the LED indicates whether the first circuit is not correctly mounted to the conductors P and PE of the current source 2.
Med en pumpstation enligt föredragen utföringsform aktiveras en sensor t ex vid uppbrytning av pumpstation- ens yttre hölje. Sensorn sluter då den andra kretsen vilken då medför att den första kretsen sluts vilken i sin tur ger en felström mellan fasledaren och skyddsjord- ledaren vilka är anordnade mellan strömkällan och pump- stationen. När felströmmen uppstår bryter strömkällan strömtillförseln, vilket gör det omöjligt att tanka brän- sle från pumpstationen.With a pump station according to the preferred embodiment, a sensor is activated, for example, when the outer housing of the pump station is broken. The sensor then closes the second circuit which then causes the first circuit to close which in turn gives a fault current between the phase conductor and the protective earth conductor which are arranged between the current source and the pump station. When the fault current occurs, the power source interrupts the power supply, which makes it impossible to refuel from the pump station.
En variant av uppfinningen är att styra strömbryt- aren 12 med en kombination av flera olika typer av sen- sorer såsom ljus-, tryck-, magnet-, vibration-, spännings- rörelse- och/eller mekaniska sensorer. En annan variant av uppfinningen är att den första kretsen 4 på annat sätt än beskrivet leder bort ström från fasled- aren P och orsakar en differens, vanligtvis större än 30mA, mellan fasledarens och nolledarens elektriska strömmar.A variant of the invention is to control the switch 12 with a combination of several different types of sensors such as light, pressure, magnetic, vibration, voltage motion and / or mechanical sensors. Another variant of the invention is that the first circuit 4 dissipates current from the phase conductor P in a manner other than described and causes a difference, usually greater than 30mA, between the electric currents of the phase conductor and the neutral conductor.
Avslutningsvis skall påpekas det inses att uppfinn- ingen kan tillämpas för att skydda mànga olika typer av spänningsförsedda anordningar.Finally, it should be pointed out that the invention can be applied to protect many different types of live devices.
