Abstract

Bei Wartungs- und Reparaturarbeiten an Schaltanlagen, insbesondere an luftisolierten Schaltanlagen für Nennspannungen ab 6 kV, gelten im Allgemeinen sehr hohe Sicherheitsstandards. Unter anderem ist darauf zu achten, dass spannungsführende Anlagenteile vor und hinter der Arbeitsstelle freigeschaltetet, d.h. von der Nennspannung getrennt, und sachgemäß geerdet werden. Zur Erdung verwendet man häufig mobile Erdungs- und Kurzschließvorrichtungen. Für die Dauer der Wartungs- und Reparaturarbeiten sind die freigeschalteten und geerdeten Anlagenteile gegen Wiederzuschalten der Nennspannung zu sichern, um die arbeitenden Personen oder Wartungskolonnen nicht zu gefährden und auch um Sachschäden zu vermeiden.For maintenance and repair work on switchgear, especially on air-insulated switchgear for Nominal voltages above 6 kV are generally very high Safety standards. Among other things, care must be taken that live system parts in front of and behind the Workplace activated, i.e. from the nominal voltage disconnected and properly grounded. For grounding one often uses mobile grounding and Short-circuiting devices. For the duration of maintenance and Repair work is the unlocked and grounded System parts against reconnection of the nominal voltage secure to working people or maintenance columns not endangered and also to avoid damage to property.

Zur Sicherung der Arbeitstelle wird eine Schutzvorrichtung vorgeschlagen, die ein berühungsloses Objekt-Identifikationssystem (1, 2) aufweist, das erkennt, wenn die mobile Erdungsvorrichtung (EUK) in die Schaltanlage eingesetzt ist und das dann die Schaltanlage gegen das Wiederzuschalten der Anlagenteile verriegelt. Das Objekt-Identifikationssystem besteht vorzugsweise aus einem Transponder (1), der an der mobilen Erdungsvorrichtung (EUK) angebracht ist, und aus einer Sende- und Empfangseinheit (2), die den Trennschalter der Schaltanlage elektrisch verriegelt, solange sich der Transponder (1) im Sende- und Empfangsbereich der Sende- und Empfangseinheit (2) befindet. Durch diese Maßnahmen wird eine automatische Sicherung gegen zu frühes Wiederzuschalten von freigeschalteten Anlageteilen erreicht, wobei durch den Einsatz eines berühungslosen Objekt-Identifikationssystems ein sehr zuverlässiges Erkennen des Erdungszustandes ermöglicht wird. Die erfindungsgemäße Sicherung der Schaltanlage ist sehr sicher, insbesondere gegen menschliches Versagen. Fehlschaltungen oder andere Gefahrenquellen sind ausgeschlossen.

Figure 00000001
To protect the work place, a protective device is proposed which has a non-contact object identification system (1, 2) which detects when the mobile earthing device (EUK) is inserted in the switchgear and then locks the switchgear against the system parts being switched on again. The object identification system preferably consists of a transponder (1), which is attached to the mobile earthing device (EUK), and a transmitter and receiver unit (2), which electrically locks the switch disconnector as long as the transponder (1) located in the transmission and reception area of the transmission and reception unit (2). These measures automatically secure the system parts from being switched on again too early, with the use of a non-contact object identification system enabling very reliable detection of the earthing condition. Securing the switchgear according to the invention is very safe, especially against human error. Incorrect switching or other sources of danger are excluded.
