Abstract
Description
Diese BGVA2-Steckdosenleiste soll es Unternehmen ermöglichen, auf einfache und vor allem günstige Art, den Forderungen der Unfallverhütungsvorschrift BGVA2(VBG4) § 5 für ortsveränderliche elektrische Betriebsmittel mit Hilfe von Differenzstrommessungen als RISO-Ersatzmessungen nach DIN VDE 0702 gerecht zu werden.This BGVA2 power strip is supposed to enable companies to on simple and above all cheap Type, the requirements of the accident prevention regulation BGVA2 (VBG4) § 5 for portable electrical Equipment using residual current measurements as RISO replacement measurements according to DIN VDE 0702.
Bei der jetzigen Methode ist die Verhältnismäßigkeit zwischen Risikominimierung in Bezug auf Brand- u. Personenschutz und dem finanziellem Aufwand fraglich, bzw. von vielen Unternehmen einfach nicht finanzierbar.With the current method it is proportionality between minimizing risk in relation to fire and personal security and the financial expense questionable, or by many companies simply not affordable.
Der in Schutzanspruch 1 angegebenen Erfindung, liegt das Problem zugrunde, eine Vorrichtung zu schaffen, mit der elektrotechnische unterwiesenen Personen auf einfachste Art, gefahrlos und zeiteffektiv den Schutzleiterwiderstand RSL, den Fehlerstrom IF bei Schutzklasse I-Geräten (Schutzanspruch 4) und den Berührungsstrom IB bei Schutzklasse II-Geräten (Schutzanspruch 4) als zugelassene Ersatzmessungen für den Isolationswiderstand nach DIN VDE 0702 messen können.The invention specified in protection claim 1 is based on the problem of creating a device with which instructed persons in the simplest way, safely and time-effectively the protective conductor resistance R SL , the fault current IF in protection class I devices (protection claim 4) and the touch current IB for protection class II devices (protection claim 4) as approved replacement measurements for the insulation resistance according to DIN VDE 0702.
Die eingestöpselten elektrischen Betriebsmittel werden ausgeschaltet.The plugged in electrical equipment are turned off.
Nun wird der RSL jedes
einzelnen Schutzklasse I-Gerätes
mit Hilfe der Sonde(9) gemessen. Die LED
Nun werden die eingestöpselten Geräte nacheinander eingeschaltet.Now the plugged in Devices one after the other switched on.
Zeigt die LED
Nun wird das Sondenkabel in die Buchse PE (6) gestöpselt. Die BGVA2-Steckdosenleiste erkennt automatisch, dass nun der IB gemessen werden soll, und stellt den Grenzwert für die LED-Anzeige von 3,5 mA auf 0,5 mA um.Now the probe cable is plugged into the socket PE (6) . The BGVA2 socket strip automatically recognizes that the IB should now be measured and changes the limit for the LED display from 3.5 mA to 0.5 mA.
Der Anwender kontaktiert nun nacheinander die
berührbaren
metallenen Teile der Schutzklasse II-Geräte. Die LED
Zusätzlich zu den BGVA2-Messvorrichtungen wird der Brandschutz vergrößert in Bezug auf unvollkommene Schlüsse zwischen L und N an elektrischen Geräten (Schutzanspruch 2). Induktiv wird der Gesamtstrom IGes der Steckdosenleiste gemessen (1).In addition to the BGVA2 measuring devices, fire protection is increased with regard to imperfect connections between L and N on electrical devices (protection claim 2). The total current I Ges of the power strip is measured inductively (1) .
Abhängig von der Kennlinie einer 1,5 qmm Kupferleitung bei der gängigsten Verlegeart B2 wird eine zeitgesteuerte allpolige Abschalteinrichtung eingebaut, welche die höheren Einschaltströme der gängigsten ortsveränderlichen elektrischen Büro-Geräte berücksichtigt.Depending on the characteristic curve 1.5 sqmm copper wire for the most common Installation type B2 becomes a time-controlled all-pole switch-off device built in, which the higher inrush the most common portable electrical office equipment.
Gleichzeitig wird noch als zusätzlicher Personenschutz eine Fehlerstromschutzschaltung realisiert, welche bei IDIFF > 30mA schnellstmöglich die Steckdosenleiste allpolig vom Netz trennt (2).At the same time, a residual current protection circuit is implemented as additional personal protection, which isolates the power strip all poles from the mains as quickly as possible with I DIFF > 30mA (2) .
Fünf Steckplätze für elektrische Betriebsmittel.five slots for electrical Resources.
Ein Steckplatz (10) um eine weitere BGVA2-Steckdosenleiste selektiv nutzen zu können.One slot (10) to selectively use another BGVA2 socket strip.
Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnungen 1 und 2 erläutert. Es zeigen:An embodiment of the invention will be explained with reference to drawings 1 and 2. Show it:
Zeichnung 1 eine Skizze der BGVA2-Steckdosenleiste bei der Messung des Schutzleiterwiderstandes RSL, sowie der Messung des Fehlerstromes IF bei einem Schutzklasse I – Gerät/PrüflingDrawing 1 shows a sketch of the BGVA2 socket strip when measuring the protective conductor resistance R SL , as well as measuring the fault current I F for a protection class I device / device under test
Zeichnung 2 eine Skizze der BGVA2-Steckdosenleiste bei der Messung des Berührungsstromes IB bei einem Schutzklasse II – Gerät/Prüfling In den Zeichnungen ist die BGVA2-Steckdosenleiste als Skizze veranschaulicht.Drawing 2 shows a sketch of the BGVA2 socket strip when measuring the contact current I B for a protection class II device / device under test. The BGVA2 socket strip is illustrated as a sketch in the drawings.
Das zeitüberprüfende Überstromschutzorgan (1), der Differenzstrommesser (3), das Ohmmeter (5), das Relais für die allpolige Abschaltung (2), die Buchse PE für die Messung des Berührungsstromes IB (6), die Buchse RSL für die Messung des Schutzleiterwiderstandes RSL (8), das Sondenkabel mit der Sonde (9), die fünf Steckplätze für mobile elektrische Betriebsmittel und den Steckplatz für eine weitere selektive BGVA2-Steckdosenleiste (10).The time-checking overcurrent protection device (1) , the residual current meter (3) , the ohmmeter (5) , the relay for all-pole disconnection (2) , the socket PE for measuring the touch current IB (6) , the socket R SL for measuring the Protective conductor resistance R SL (8) , the probe cable with the probe (9) , the five slots for mobile electrical equipment and the slot for another selective BGVA2 socket strip (10) .
Die BGVA2-Steckdosenleiste erkennt
automatisch, dass das Sondenkabel in der Buchse RSL steckt
und stellt den Grenzwert für
die LED
Dies hat den Vorteil, dass man nicht mehr nur auf den Thermoschutz über Bi-Metall in der Unterverteilung im LS-Schalter angewiesen ist. Denn je nach Kennlinie, Verlegeart und Umgebungstemperatur dieser LS-Schalter kann es vor der Abschaltung schon zu unzulässig hoher Erwärmung der Leitung kommen.This has the advantage that you cannot more just on thermal protection Bi-metal is instructed in the sub-distribution in the circuit breaker. Because depending on the characteristic, installation type and ambient temperature Circuit breakers can be too high before they are switched off warming come the line.
Der Differenzstrommesser (3) wird gleichzeitig noch für eine FI-Schutzschaltung genutzt. Bei einem IDI FF größer 30mA wird die Steckdosenleiste über das Relais K (2) schnellstmöglich allpolig vom Netz getrennt.The residual current meter (3) is also used for a residual current circuit. In the case of an I DI FF greater than 30mA, the multiple socket is disconnected from the mains as quickly as possible via the relay K (2) .
