Pri tem je izum osnovan na problemu, kako zasnovati napravo za prekinitev primarnega električnega tokokroga pri vozilu na električni pogon v primeru trka, namreč električnega tokokroga med vsakokratnim električnim pogonskim sredstvom in vsakokrat razpoložljivim virom električne energije za napajanje omenjenega električnega pogonskega sredstva, ki bo brez vsakršnih škodljivih učinkov, še zlasti brez formiranja obloka, požara, dima ali eksplozije, omogočala popolno prekinitev vsakršne električne povezave med vsakokratnim električnim pogonskim sredstvom in vsakokrat razpoložljivim virom električne energije za napajanje omenjenega električnega pogonskega sredstva vključno s preostalimi porabniki, ki so priključeni na vsakokratni vodnik za povezavo električnega pogonskega sredstva z vsakokrat razpoložljivim virom električne energije, obenem pa naj bi v primeru, kadar je kot vir električne energije uporabljen akumulator, omogočala tudi intenzivno praznjenje akumulatorja.The invention is based on the problem of how to design a device for interrupting the primary electrical circuit of an electric vehicle in the event of a collision, namely the electrical circuit between each electric drive means and each available source of electricity to power said electric drive means. adverse effects, in particular without the formation of an arc, fire, smoke or explosion, made it possible to completely disconnect any electrical connection between each electric propulsion device and each available source of electricity to supply said electric propulsion means, including other consumers connected to the respective conductor. connection of the electric propulsion means with the available source of electricity at all times, and at the same time, in the case when a battery is used as a source of electricity, it should also enable intensive discharge of the battery.
V že objavljeni mednarodni patentni prijavi št. WO 2014/065763 je opisana varovalka s talilnim elementom in z zmožnostjo prekinitve skoznjo potekajočega električnega tokokroga. Tovrstna varovalka obsega telo iz električno izolacijskega materiala, s katerim je obdan vsakokrat razpoložljiv in nazivni vrednosti električnega toka prirejen talilni element, ki je električno povezan z vsakokrat razpoložljivima električnima kontaktoma, ki sta razporejena na zunanji površini omenjenega telesa varovalke in preko katerih je varovalka električno povezljiva v vsakokrat razpoložljiv primarni električni tokokrog, ki je zaščiten s pomočjo varovalke. Tovrstna varovalka nadalje obsega upor, še zlasti od električne napetosti odvisen upor, namreč varistor, katerega upornost je obratno sorazmerna z napetostjo, kateri je izpostavljen, pri čemer je omenjen upor razporejen neposredno ob talilnem elementu in torej v toplotno-prevodnem stiku z omenjenim talilnim elementom. Omenjeni upor je električno povezan v sekundami električni tokokrog z vsaj enim stikalom, ki ga je možno po potrebi aktivirati neodvisno od razmer v primarnem tokokrogu. Tovrstno rešitev je načeloma možno uporabiti tudi kot napravo za prekinitev primarnega električnega tokokroga pri vozilu na električni pogon v primeru trka. V primeru, kadar gre pri omenjenem uporu za klasičen upor, pri sklenitvi omenjenega stikala in s tem sekundarnega tokokroga obstoji možnost, da se v območju stikala pojavi oblok. Kadar je omenjeni upor izbran kot varistor, je v primeru trka vozila tovrstna varovalka zmožna prekiniti zgolj enega izmed obeh vodnikov med virom električne energije in električnim pogonskim sredstvom, medtem ko preostali vodnik vključno z vsemi nanj priključenimi porabniki ostaja v električnem stiku tako z virom električne napetosti kot tudi s pogonskim sredstvom.In the already published international patent application no. WO 2014/065763 describes a fuse with a melting element and the ability to interrupt an electrical circuit passing through it. Such a fuse comprises a body made of electrically insulating material, which surrounds the available and adapted to the nominal value of electric current melting element, which is electrically connected to the available electrical contacts, which are arranged on the outer surface of said fuse body and through which the fuse is electrically connected. in the available primary electrical circuit at any time, which is protected by a fuse. Such a fuse further comprises a resistor, in particular a voltage-dependent resistor, namely a varistor whose resistance is inversely proportional to the voltage to which it is exposed, said resistor being arranged directly adjacent to the melting element and thus in thermally conductive contact with said melting element . Said resistor is electrically connected in seconds to an electrical circuit with at least one switch which can be activated if necessary independently of the conditions in the primary circuit. In principle, such a solution can also be used as a device to interrupt the primary electrical circuit of an electric vehicle in the event of a collision. In the case of said resistor, it is a classical resistor, when concluding said switch and thus the secondary circuit, there is a possibility that an arc appears in the area of the switch. When this resistor is selected as the varistor, in the event of a vehicle collision, such a fuse is capable of breaking only one of the two conductors between the power source and the electric drive, while the remaining conductor, including all connected consumers, remains in electrical contact with both the voltage source. as well as with the propellant.

Pri tem je varistor v vsaki izmed omenjenih varovalk razporejen v toplotno prevodnem in obenem tudi električnem stiku z vsakokrat pripadajočim talilnim elementom, obenem pa je vsak izmed omenjenih varistorjev električno povezan s stikalom, ki je prirejeno za vzpostavitev ali prekinitev medsebojnega električnega stika med obema varistorjema omenjenih varovalk. Vsakokraten varistor je prednostno kar prispajkan na vsakokrat pripadajoč talilni element varovalke, omenjeno stikalo pa prednostno predstavlja elektromagnetno stikalo z avtonomnim električnim napajanjem.According to the invention, the above-mentioned problem is solved by the fact that in each of the electrical conductors for connecting the electric drive means with a power source, one fuse with a melting element and a varistor is installed, and the electric drive means with a power source in each of said conductors connected via a fuse element of each fuse.

Izum bo v nadaljevanju obrazložen s primerom izvedbe, ki je prikazan na priloženi skici, kjer Sl. 1 kaže shematično ponazorjeno napravo za prekinitev primarnega električnega tokokroga pri vozilu na električni pogon, še zlasti v primeru trka.The invention will be further illustrated by an exemplary embodiment shown in the accompanying drawing, in which FIG. 1 shows a schematically illustrated device for interrupting the primary electrical circuit of an electric vehicle, especially in the event of a collision.
Naprava za prekinitev primarnega električnega tokokroga pri vozilu na električni pogon, še zlasti v primeru trka vozila, ki je shematično ponazorjena na Sl. 1, je vgradljiva med vsakokratno električno pogonsko sredstvo 1 vozila in vsakokraten vir 2 električne energije.Device for interrupting the primary electrical circuit of an electric vehicle, in particular in the event of a vehicle collision, which is schematically illustrated in FIG. 1, is installed between the respective electric drive means 1 of the vehicle and the respective source 2 of electricity.
Vir 2 električne energije pri vozilih na električni pogon običajno predstavlja akumulator oz. baterija v funkciji visokonapetostnega vira enosmerne električne napetosti, medtem ko pogonsko sredstvo 1 predstavlja ustrezen elektromotor.The source 2 of electricity in electric vehicles is usually the battery or. the battery serves as a high-voltage source of direct current voltage, while the drive means 1 represents a corresponding electric motor.
Omenjeno pogonsko sredstvo 1 in vir 2 električne energije sta drug z drugim električno povezljiva v primarni električni tokokrog preko dveh električnih vodnikov 21, 22.Said drive means 1 and the power source 2 are electrically connected to each other in a primary electrical circuit via two electrical conductors 21, 22.
Po izumu je v vsakem izmed omenjenih električnih vodnikov 21, 22 za povezavo električnega pogonskega sredstva 1 z virom 2 električne energije vgrajena po ena varovalka 3', 3 s talilnim elementom 3Γ, 31 in varistorjem 32', 32, tako daje električno pogonsko sredstvo 1 z virom 2 električne energije v vsakem izmed omenjenih vodnikov 21, 22 povezano preko talilnega elementa 3Γ, 31 vsakokratne varovalke 3', 3. V primeru električne preobremenitve oz. nadtoka se talilni element 3Γ, 31 stali in prekine omenjen primarni električni tokokrog. Vsak izmed omenjenih varistorjev 32', 32 je v osnovi predviden za prisilno prekinitev tokokroga v območju vsakokrat pripadajočega talilnega elementa 3Γ, 31 tudi v primeru, kadar tok skozi talilni element 3Γ, 31 ne presega vnaprej določene vrednosti, ki bi povzročila taljenje in prekinitev talilnega elementa 3Γ, 31 zaradi nadtoka.According to the invention, in each of said electrical conductors 21, 22, a fuse 3 ', 3 with a fuse element 3Γ, 31 and a varistor 32', 32 is installed to connect the electric drive means 1 to the power source 2, so that the electric drive means 1 with a source 2 of electricity in each of said conductors 21, 22 connected via a melting element 3Γ, 31 of each fuse 3 ', 3. In the event of an electrical overload or. overcurrent, the melting element 3Γ, 31 melts and interrupts said primary electrical circuit. Each of said varistors 32 ', 32 is basically designed to forcibly interrupt the circuit in the range of the corresponding melting element 3Γ, 31 even when the current through the melting element 3Γ, 31 does not exceed a predetermined value that would cause melting and interruption of the melting element. element 3Γ, 31 due to overcurrent.
Vsakokraten varistor 32', 32 predstavlja električni upor, katerega upornost je odvisna od električne napetosti, in sicer obratnosorazmemo.Each varistor 32 ', 32 represents an electrical resistor, the resistance of which depends on the electrical voltage, inversely.
Po izumu je predvideno, da je vsakokraten varistor 32', 32 v vsaki izmed omenjenih varovalk 3', 3 na voljo v toplotno prevodnem in obenem tudi električnem stiku z vsakokrat pripadajočim talilnim elementom 3Γ, 31. Še zlasti je prednostno, če je varistor 32', 32 na vsakokrat pripadajoč talilni element 3Γ, 31 vsakokratne varovalke 3', 3 kar prispajkan.According to the invention, it is provided that each varistor 32 ', 32 in each of said fuses 3', 3 is available in thermally conductive and at the same time electrical contact with the corresponding melting element 3Γ, 31. It is particularly preferred if the varistor 32 ', 32 on each fuse element 3Γ, 31 of each fuse 3', 3 is soldered.
Obenem je vsak izmed omenjenih varistorjev 32', 32 električno povezan s stikalom 4, ki je prirejeno za vzpostavitev ali prekinitev medsebojnega električnega stika obeh varistorjev 32', 32 omenjenih varovalk 3', 3. Omenjeno stikalo 4 je prednostno izvedeno kot elektromagnetno stikalo z avtonomnim električnim napajanjem, npr. z napetostjo 12 V.At the same time, each of said varistors 32 ', 32 is electrically connected to a switch 4 adapted to establish or break the mutual electrical contact of the two varistors 32', 32 of said fuses 3 ', 3. Said switch 4 is preferably designed as an electromagnetic switch with an autonomous power supply, e.g. with a voltage of 12 V.
Na Sl. 1 je stikalo 4 razklenjeno in preko vodnikov 21, 22 z integriranima talilnima elementoma 3Γ, 31 varovalk 3', 3 je vzpostavljen primarni električni tokokrog med pogonskim sredstvom 1 in virom 2 električne energije.In FIG. 1, the switch 4 is unlocked and a primary electrical circuit is established between the drive means 1 and the power source 2 via conductors 21, 22 with integrated fuse elements 3Γ, 31 fuses 3 ', 3.
Z aktiviranjem stikala 4, še zlasti npr. v primeru trka vozila, se vzpostavi električna povezava med obema varistorjema 32', 32 varovalk 3', 3, s čimer se formira sekundami tokokrog, ki vključuje vir 2 električne energije, vodnika 21, 22 ter talilna elementa 3 Γ, 31 in varistorja 32', 32 obeh varovalk 3', 3. Ob vzpostavitvi omenjenega sekundarnega tokokroga s pomočjo stikala 4 je tok skozi oba varistorja 32', 32 zahvaljujoč njuni karakteristiki razmeroma nizek, zato v stikalu 4 ne pride do formiranja obloka, iskrenja ali drugih škodljivih pojavov. Šele zatem se jakost toka skozi varistorja 32', 32 poveča, zaradi česar se varistorja 32', 32 intenzivno segrevata, posledično pa se potem stali vsakokrat pripadajoč talilni element 3 Γ, 31 in prekine vsakokrat pripadajoč električni vodnik 21, 22 ter s tem loči pogonsko sredstvo 1 in eventualne druge električne porabnike, ki so vezani na vsakega izmed omenjenih vodnikov 21, 22, od vira 2 električne energije.By activating switch 4, in particular e.g. in the event of a vehicle collision, an electrical connection is established between the two varistors 32 ', 32 fuses 3', 3, thus forming a circuit for seconds, which includes power source 2, conductor 21, 22 and melting element 3 Γ, 31 and varistor 32 ', 32 of both fuses 3', 3. When establishing said secondary circuit by means of switch 4, the current through both varistors 32 ', 32 is relatively low due to their characteristic, therefore no arc formation, sparking or other harmful phenomena occur in switch 4. Only then does the current through the varistor 32 ', 32 increase, causing the varistors 32', 32 to heat up intensely, and consequently the corresponding melting element 3 Γ, 31 melts and the corresponding electrical conductor 21, 22 is interrupted, thus separating drive means 1 and any other electrical consumers connected to each of said conductors 21, 22 from the power source 2.
