Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to a device according to the features of the preamble of claim 1
Zwar kann generell eine solche Vorrichtung, die dem Schutz vor Berührungen mit spannungsführenden Teilen in einem Zugangsbereich zu einem elektrischen System dient grundsätzlich überall da eingesetzt werden, wo die Gefahr besteht, dass auch mit dem elektrischen System nicht vertraute Personen den Zugangs- oder Anschlussbereich, wie den Anschluss- oder Klemmenkasten, öffnen. Im Besonderen ist dies jedoch bei den neuartigen Hybridantrieben von Straßenfahrzeugen der Fall, die in Fahrzeugwerkstätten gewartet und gegebenenfalls repariert werden müssen.Though can generally be such a device that protects against contact with live Parts in an access area to an electrical system is used basically used everywhere be where the danger exists, even with the electrical system unfamiliar persons the access or connection area, such as open the connection or terminal box. In particular, this is However, in the novel hybrid drives of road vehicles the case in vehicle workshops have to be serviced and possibly repaired.
Bei derartigen Hybridantrieben muss zur Vermeidung hoher Ströme der bis zu einer Spannung von 50 Volt als sicher geltende Spannungsbereich verlassen werden, so wird insbesondere bei Nutzfahrzeugen und Bussen wegen der hier notwendigen höheren Antriebsleistungen mit Spannungen von mehr als 600 Volt gearbeitet.at Such hybrid drives must to avoid high currents of up to leave a voltage of 50 volts as safe voltage range especially for commercial vehicles and buses the higher one needed here Drive services worked with voltages of more than 600 volts.
Wegen dieser Erhöhung der Versorgungsspannung wird ein Schutz vor direkter und indirekter Berührung spannungsführender Teile notwendig, der im Wartungs- und Reparaturfall das Servicepersonal in den Fahrzeugwerkstätten vor den Gefahren eines elektrischen Schlages schützt. Insbesondere muss dem Umstand Rechnung getragen werden, dass sich das heute vorhandene Werkstattpersonal mit den aufgezeigten Gefahren noch nicht auskennt solange nicht entsprechende Ausbildungsprogramme absolviert worden sind.Because of this increase The supply voltage is a protection against direct and indirect contact live Parts necessary, in the case of maintenance and repair, the service personnel in the vehicle workshops protects against the dangers of an electric shock. In particular, the must Be taken into account that the existing today Workshop personnel with the indicated dangers are not yet familiar as long as appropriate training programs have not been completed are.
In Fahrzeug-Hybrid-Antriebssystemen können gefährliche Spannungen aus folgenden Quellen stammen: Es sind Stromspeicher vorhanden, die nicht nur aus dem Batteriesystem oder Brennstoffzellen bestehen. Insbesondere kommen hierfür geladene Kondensatoren, wie Doppelschicht-Kondensatoren in Betracht, die im Gleichspannungszwischenkreis des Umrichtersystems zwischen der Drehstrommaschine und den Gleichspannungs-Akkumulatoren eingesetzt werden. Auch im ausgeschalteten Zustand des Antriebssystems können höhere Spannungen noch längere Zeit gespeichert bleiben und stellen eine potentielle Gefährdung dar, sobald servicebedingte oder reparaturbedingte Eingriffe in das System vorgenommen werden müssen. Diese Gefährdung muss auch dann beherrscht werden, wenn beispielsweise nach einem Unfall das System beschädigt ist und Defekte aufweist. Es kann sich um Isolationsdefekte im Energiespeicher, um Isolationsdefekte im Antriebswechselrichter oder im übrigen Antriebssystem handeln, auch kommen ausgefallene oder kurzgeschlossene Schütze oder Relais zu den Akkumulatoren hin oder Unterbrechungen oder Wackelkontakte in Betracht, letztere können eine Entladung der Zwischenkreiskondensatoren verhindern.In Vehicle hybrid propulsion systems can cause dangerous voltages Sources come from: There are power storage devices that not only consist of the battery system or fuel cells. Especially come for this charged capacitors, such as double-layer capacitors, in the DC voltage intermediate circuit of the inverter system between the three-phase machine and the DC accumulators used become. Even when the drive system is switched off, higher voltages can occur even longer Remain stored and represent a potential hazard as soon as service-related or repair-related interferences with the system must be made. This danger must be mastered even if, for example, after a Accident damaged the system is and has defects. It may be insulation defects in the energy storage, Insulation defects in the drive inverter or in the rest of the drive system act, also come outfitted or shorted Sagittarius or Relays to the accumulators or interruptions or loose contacts into consideration, the latter can prevent a discharge of the DC link capacitors.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, mit der die span nungsführenden Teile im Zugangsbereich des elektrischen Systems kurzgeschlossen werden, bevor der Zugang zu dem Zugangsbereich freigegeben wird.Of the The invention is therefore based on the object, a device of to create the aforementioned type, with the voltage-carrying voltage Parts shorted in the access area of the electrical system before access to the access area is released.
Diese Aufgabe wird nach der Erfindung mit einer Vorrichtung gelöst, welche die Gesamtheit der Merkmale des Patentanspruchs 1 aufweist.These The object is achieved according to the invention with a device which comprising the entirety of the features of claim 1.
Für die erfindungsgemäße Lösung ist wesentlich, dass der Kurzschluss derjenigen Teile im Zugangsbereich, die Spannungen unterschiedlicher Polarität auch dann führen können, wenn das elektrische System außer Betrieb ist, zwangsläufig bei Verstellung des Betätigungsteils am Verschlussteil kurzgeschlossen werden, ohne dass darauf Einfluss genommen werden kann. So ist das Wartungspersonal beim Zugang zu dem Zugangsbereich, wie dem Anschluss- oder dem Klemmenkasten des elektrischen Systems, sicher vor gefährlichen Spannungen geschützt.For the solution according to the invention essential that the short circuit of those parts in the access area, the voltages of different polarity can lead even if the electrical system except Operation is, inevitably at adjustment of the operating part be short-circuited on the closure part, without affecting it can be taken. So is the maintenance staff when accessing the access area, such as the connection or terminal box of the electrical system, safely protected from dangerous voltages.
Vorteilhafte Ausgestaltungsmerkmale der Erfindung ergeben sich aus den Unteransprüchen.advantageous Design features of the invention will become apparent from the dependent claims.
Die Erfindung wird nachfolgend anhand der Zeichnung noch näher erläutert.The Invention will be explained in more detail with reference to the drawing.

Einzelnen erkennt man in
Im Wartungs- oder Reparaturfall muss man Zugang zu den Anschlüssen der Komponenten des Antriebssystems nehmen, dies geschieht über den Anschlussbereich A, der über einen Zugangsbereich Z zu gänglich ist. Bevor der Zugang zu dem Anschlussbereich A geöffnet wird, muss sichergestellt sein, dass in dem Anschlussbereich A Berührungen der Bedienungspersonen mit Bauteilen, die eine gefährliche Spannung führen können, ausgeschlossen sind. Solche menschengefährdende Spannungen können im Gleichspannungskreis GK insbesondere bei nicht entladenem Kondensator K auftreten. Ebenso können Fehler im elektrischen Energiespeicher S zu den gefährlichen Berührungsspannungen führen, wie auch Fehler in anderen Energiequelle oder in elektrischen Steuerungen des Antriebssystems.in the Maintenance or repair case you have access to the terminals of the Take components of the drive system, this is done via the connection area A, over an access area Z accessible is. Before access to the connection area A is opened, It must be ensured that in the connection area A touches the Operators with components that can carry a dangerous voltage are excluded. Such people-endangering Tensions can in the DC voltage circuit GK, in particular when the capacitor is not discharged K occur. Likewise Error in the electrical energy storage S to dangerous touch voltages lead, like also errors in other energy source or in electrical controls of the drive system.
