Abstract

Namen izuma je zasnovati napravo za prekinitev primarnega električnega tokokroga pri vozilu na električni pogon v primeru trka, namreč električnega tokokroga med vsakokratnim električnim pogonskim sredstvom (1) in vsakokrat razpoložljivim virom (2) električne energije za napajanje omenjenega električnega pogonskega sredstva (1), ki bo brez vsakršnih škodljivih učinkov, še zlasti brez formiranja obloka, požara, dima ali eksplozije, omogočala popolno prekinitev vsakršne električne povezave med vsakokratnimelektričnim pogonskim sredstvom (1) in vsakokrat razpoložljivim virom (2) električne energije za napajanje omenjenega električnega pogonskega sredstva (1). Po izumu je predvideno, daje v vsakem od električnih vodnikov (21, 22) za povezavo električnega pogonskega sredstva (1) z virom (2) električne energije vgrajena po ena varovalka (3', 3") s talilnim elementom (31', 31") in varistorjem (32', 32"), tako da je električno pogonsko sredstvo (1) z virom (2) električne energije v vsakem izmedomenjenih vodnikov (21, 22) povezano preko talilnega elementa (31', 31") vsakokratne varovalke (3', 3"). Vsakokraten varistor (32', 32") v vsaki izmed omenjenih varovalk (3', 3") je na voljo v toplotno prevodnem in obenem tudi električnem stiku z vsakokrat pripadajočim talilnim elementom (31', 31"), obenem pa je vsak izmed omenjenih varistorjev (32', 32") električno povezan s stikalom (4), ki je prirejeno za vzpostavitev ali prekinitev medsebojnega električnega stika med obemavaristorjema (32', 32") omenjenih varovalk (3', 3").The purpose of the invention is to provide 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 (1) and each available source (2) of power for supplying said electric drive means (1). will allow, without any adverse effects, in particular without the formation of an arc, fire, smoke or explosion, to completely disconnect any electrical connection between each electric propulsion means (1) and the available source (2) of electricity to supply said electric propulsion means (1). According to the invention, it is provided that one fuse (3 ', 3 ") with a melting element (31', 31) is installed in each of the electrical conductors (21, 22) for connecting the electric drive means (1) to the power source (2). ") and a varistor (32 ', 32"), so that the electric drive means (1) is connected to the source (2) of electricity in each of the said conductors (21, 22) via a fuse element (31', 31 ") of each fuse (3 ', 3 "). 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 (31', 31"). "), and at the same time each of said varistors (32 ', 32") is electrically connected to a switch (4) adapted to establish or interrupt the electrical contact between the two varistors (32', 32 ") of said fuses (3 ', 3 ").
