Definitions

  • the invention relates to a device for monitoring a state of an electrical switching device with a status indicator which is covered or enabled as a function of the state of the switching device.
  • the ⁇ known switching device is designed as a circuit breaker and includes a housing, a power supply and a Lastan- conclusion. Between the mains connection and the load connection a switchable contact point is arranged. In a triggering of the electrical switching device, a so-called trigger ⁇ is actuated cam and there is an opening of the switchable contact point of the known electrical switching device.
  • a state indicator is provided. The state indicator is designed in the form of a pivotable rocker. This rocker is pivoted as a function of the switching state of the ⁇ known switching device and is either visible through a window or pivoted ge behind a cover.
  • the force for the movement of the switching contact piece of the switchable contact point of the switching device is a force to apply the movement of the status indicator.
  • a lightweight construction is selected for the condition indicator. WEI terhin the pivot bearing of the condition indicator is inferior to a frequent switching a greater wear.
  • the invention is therefore based on the object, a Vorrich ⁇ processing for monitoring to provide an electrical switching device which has als ⁇ a state indicator having a long life and ensures a reli ⁇ transmissive display of the switching state of a condition.
  • the object is achieved in a device of the type mentioned in the present invention that the state indicator remains ⁇ tor during a switching operation at rest.
  • the switching operations on electrical switching devices often take place suddenly. Due to a rapid switching operation and vibrations can occur, which extend over the entire switching device. If one chooses a state indicator which remains at rest during a switching operation, shock and vibration phenomena can no longer be superposed with a movement of the status indicator. This improves the durability of the condition indicator. Since now the movement of the switching contacts of the switching device is decoupled from an optionally existing movement of the state indicator, the necessary drive energy can be reduced. Characterized the energy storage can be reduced as well as the kinematic chain for transmitting the movement ge ⁇ be dimensioned ringer. A further advantageous embodiment can provide that the status indicator maps the switching state of the electrical switching device.
  • the switching contacts of an electrical switching device are often ⁇ times not directly visible. Envelopes, such as arc extinguishing chambers or the like, prevent di ⁇ direct insight. For an operator or user of an electrical switching device, however, it is necessary to detect the switching state. As a result, for example, a reliable determination of a disconnected Kirsabschnit ⁇ tes done.
  • tapers to the state indicator comprises a visual axis for reading, which is interrupted or due to a driving movement of a kinematic chain for driving a switching contact piece give frge ⁇ .
  • the switching contact pieces are used to cover the state indicator , a very reliable status indication is ensured. Thus, even with a fault, for example, ⁇ bending a lever in the kinematic chain of the drive train always the current switching position of the switching contact pieces are displayed. It can be provided that move the movable switching contact pieces of a switching contact of the electrical switching device in a view ⁇ axis for reading the status indicator.
  • the status indicator is subdivided into a plurality of coverable areas.
  • a subdivision of the status indicator can be effected, for example, by arranging a scaling at which a progress of the switching operation can be read off.
  • a risk assessment for example in the case of a faulty position or blocking of a movable switching contact piece during a switching operation.
  • the status indicator has different areas, which are characterized, for example, by color-different markings, by a coding in the form of letters, numbers, barcodes or the like.
  • a further advantageous embodiment can provide that the status indicator can be covered by a plurality of switching contact pieces.
  • Compression-gas-tight encapsulating housings are generally made of an opaque material.
  • individual small viewing windows are embedded in the encapsulating housing.
  • the viewing axis can run to evaluate the status indicator. Since this visual axis does not have to be bound to specific devices, such as cables and wires, a design revision of the encapsulating must not be taken ⁇ before.
  • the status indicator can thereby be beispiels- example attached to a wall of the encapsulating housing or the wall of the encapsulating housing may be designed as stand indicator to ⁇ itself.
  • the state indicator is optically detectable.
  • the electrical switching devices can be, for example, disconnectors, earthing switches, combined disconnecting earthing switches, load switches, switch disconnectors or even circuit breakers. A subdivision of the status indicator into several areas allows a fast and safe reading.
  • the information readable by the status indicator can be converted and transported in electronic form over long distances. Thereby, it is possible for example that in a routing ⁇ place of distance of the switching state of a switching device via ⁇ is monitored. It is particularly advantageous in this case if passes as op ⁇ genetic sensor, a camera used. By means of Camera can be a real image of switching contacts and status indicator transmitted to the control room.
  • an additional coding can be arranged in the detection field of the optical sensor. This coding can for example be a designation of the switchgear, the switchgear, place or ähnli ⁇ ches. This makes it possible to easily obtain an overview even with remote operation or monitoring. This reduces the risk of malfunctions.
  • An advantageous embodiment may further provide that the status indicator is a planar marking.
