Definitions

  • the invention relates to a protective device according to the Preamble of claim 1 and one equipped with it Switchgear and a switchgear according to the generic term one of the subordinate claims.
  • the job is secured by manually blocking the corresponding Switching devices (e.g. circuit breakers or disconnectors), to unintentionally switch on the nominal voltage, i.e. Prevent incorrect switching. It is also known to the persons authorized to switch the fact that the Is grounded to report and visually indicate especially if these people are the job cannot see because the switching operations of away from waiting. So there is protective devices for switchgear for safe re-activation of unlocked and by means of a mobile earthing device the nominal voltage. These are known guards however only reliable to a limited extent. Not just technical Defects, such as the failure of the visual display, can occur. Human error is also at these guards to danger. It can happen that forget the message of the grounding condition or that the visual display of that switching personnel is overlooked.
  • Switching devices e.g. circuit breakers or disconnectors
  • the task of invention is to overcome disadvantages mentioned an improved protection device and to present a switchgear equipped with it.
  • the protective device has a contactless object identification system on that detects when the mobile grounding device is in the Switchgear is used and then the switchgear locked against reactivation of the system parts.
  • the use of a contactless object identification system in particular advantageous because it enables a very reliable detection of the Earthing condition is reached.
  • the invention Securing the switchgear is very safe, in particular against human error. Faulty switching or other Sources of danger are excluded.
  • that is Protective device very quickly and with little effort Can be retrofitted to existing switchgear at any time.
  • the mobile grounding device according to the invention with a Transponder, also called a tag, can be equipped also in conventional switchgear that does not have a transceiver have, are used, wherein then there is no longer any protective effect.
  • the identification system has a transponder that is arranged on the mobile grounding device, and if the identification system is a transmitting and receiving unit has that with the electrical control for one Disconnector of the switchgear is connected, and the Isolator switch electrically locked if the transponder the transmission and reception area of the transmission and Receiving unit is located. Since the transponder is an inactive electronic component, can the mobile earthing device EUK also in conventional Way of use, i.e. in the known Switchgear not with the one presented here Object.Identification system.
  • the figure shows a switchgear with a Protection device according to the invention, which is a non-contact Object identification system consisting of one Transponder 1 and from a transmitting and receiving unit 2 contains.
  • the transponder 1 is on a mobile Earthing device EUK - also earthing and Called short circuit device - arranged in the Switchgear can be used to unlock Ground system parts.
  • the mobile grounding device is in this example as a rod in the form of an earthing hook EUK trained who the line connection to be earthed 5 with the switchgear frame via a Earth connection bolt 3 connects. As long as the Earthing hook EUK inserted in the switchgear may no reactivation of the activated system parts the live line connection 4 take place.
  • the transponder 1 is in radio communication with the transmitter - and receiving unit 2. As long as the transponder 1 in Transmission and reception area is a Reactivating the system parts (here: closing the Disconnector) blocked. In this case the object identification system works assume that the mobile EUK earthing device is inserted in the switchgear, i.e. there is a grounding condition. Only when the mobile Earthing device EUK is removed from the switchgear and therefore no longer in the transmission and reception area there is a reactivation of the unlocked System parts approved.
  • the sending and receiving unit 2 is for this with a control (not shown) connected, which controls the switchgear disconnector, i.e. blocked or released.
  • the transmission and receiving unit 2 sends a signal to the controller Blockage of the disconnector. This is the disconnector locked against the nominal voltage being switched on again. Only when the transponder 1 is outside the transmission and Receiving area, sends the send and Receiving unit 2 to the control of the disconnector Enable signal.
  • the object identification system works in Microwave range.
  • the use of transponders is on is known from another technical area, namely from the field of so-called secondary radar systems, the also work in the microwave range.
  • the transponder is commonly referred to as a day.
  • every single earthing device with a transponder provided that can be identified by a unique identifier is. So every single mobile can Earthing device can be identified. However, without Influence on the basic function to protect against unintentional grounding on identification between the Tag and the transceiver are dispensed with.
  • the Sending and receiving area of the sending and receiving unit is set to the location of the mobile Earthing device fully detected. This will ensures that the system parts are switched on again only occurs when the mobile grounding device far enough away from their location. In order to it is excluded that a grounding condition at Reconnection exists and there are accidents and damage comes.
  • the invention is not based on the described Embodiment limited.
  • An inventive Safety device can also be designed so that a wireless transmission between the transceiver and Transponders via infrared signals or ultrasound signals he follows.
  • the day becomes inseparable from the mobile Grounding device EUK connected, so that its deliberate or unintentional removal, which can lead to the lifting of the Protective effect, cannot happen.
  • the Transmitter and receiver unit is in the Control circuit of the motor drive integrated, one Blockage of the switching device only in the switching state "Off" "occurs.
  • An optical signal indicates as soon as the Transmitting and receiving unit recognized the transponder or has captured.
  • the proposed protective device enables one automatic protection against reactivation of unlocked system parts, the use of a Object identification system a very inexpensive Solution compared to conventional solutions represents.
  • a Object identification system a very inexpensive Solution compared to conventional solutions represents.
  • can be costly motor-driven devices can be dispensed with.
