Definitions
- the invention relates to a gas-insulated switchgear assembly, in particular a gas-insulated medium-voltage switchgear assembly, in accordance with the precharacterizing clause of patent claim 1 .
- electrical switchgear assemblies in particular medium-voltage switchgear assemblies, also contain a disconnector, which is arranged, for example, between the circuit breaker and the busbar current path.
- This disconnector can assume two or three positions: connected position, disconnected position and possibly grounding position. This disconnector is therefore in the form of a two-position or three-position disconnector.
- the movable contact piece of the disconnector In the connected position, a connection to the voltage-carrying busbar is produced and, in the grounding position, a connection to ground is produced, for example.
- the movable contact piece of the disconnector In the disconnected position, the movable contact piece of the disconnector is located in a central position between the connected position and the grounding position.
- disconnectors are used as an independent device in the same gas area as the circuit breaker or in a separate gas area, in particular in the case of double-busbar arrangements.
- the electrical part of these devices is always part of the gas area and is connected to the drive by means of a gas-tight bushing, which drive is usually located outside the gas area and is generally in the form of a mechanical drive in medium-voltage applications.
- firstly a three-position disconnector and secondly a two-position disconnector (no grounding position) are located in the two separate busbar areas.
- the switching positions are transmitted to position displays by means of elements which are mechanically coupled to the drive and are signaled by means of auxiliary switches or proximity sensors.
- further positions (such as the grounding position, for example) can be signaled in contactless fashion via reed contacts, which results in redundant position signaling with correspondingly increased reliability.
- the invention is based on the object of meeting additional safety requirements in two-position and three-position disconnectors in gas-insulated switchgear assemblies, as well.
- the essence of the invention is that an inspection window is introduced/fitted in the housing of the switchgear assembly such that the positions of the switching contact elements can be seen from outside the housing directly or indirectly via optical means. Owing to the inspection it is possible to make sure of the switching state achieved or desired. This would be the test, for example, as to whether the disconnector has also actually arrived at the grounded position. The isolated line would thus be demonstrably safe in a working environment.
- At least the respective movable switching contact element is provided with a colored or topographical marking, which changes its position with respect to a fixed marking or reference structure depending on the switching position. It is thus easily possible for the presently reached switching position to be tested.
- the inspection window is arranged in the housing such that, as a result, the hermetic seal of the housing is maintained.
- An important factor here is the functional maintenance of the conditions of the gas-insulated switchgear assembly even when an inspection window is introduced. In a corresponding manner, the inspection window can therefore be introduced in a sealed manner into the housing.
- a pressure overload triggering device is arranged within the housing and is triggered markedly before the bursting limit of the inspection window.
- the optical means comprise at least one mirror, via which the marking or markings can be seen.
- One further advantageous refinement provides that, in order to inspect the switching positions in a polyphase arrangement, the position of the inspection window and of the markings is selected in relation to one another in such a way that the latter can be inspected safely.
- one advantageous refinement provides that, in order to inspect the switching positions, one or more inspection windows are provided.
- the design is such that illumination means are provided outside the housing which illuminate the markings for inspection thereof, in order to make it possible to clearly identify the switching state even in poor lighting conditions.
- FIG. 1 shows switching position assessment in the disconnector ON position
- FIG. 2 shows switching position assessment in the grounding device ON position.
- the visual switching position assessment makes it possible to check the switching state of the switching device located in the interior of a gas-insulated switchgear assembly easily through an inspection window 9 in the encapsulating wall of the housing 10 , which is only illustrated partially here.
- the switching position i.e. the position of the movable contact 4 in relation to the fixed contacts 1 , 2 and 3 , is assessed by means of a marking 5 on the, for example, cylindrical contact piece 4 .
- the respective switching position is in this case clearly associated with the position of the marking 5 or other prominent regions of the movable contact in relation to the fixed contacts.
- Actuation takes place via the spindle 6 , which is connected to the drive 8 .
- the switching position illustrated here is the disconnector ON position.
- switchgear assemblies which are used in the medium-voltage range, voltages of up to 40 kV are present. Since such switchgear assemblies also serve the purpose, inter alia, of isolating line regions for maintenance and extension work, safe shutdown is without doubt an extremely important requirement for the safety of human life.
- FIG. 2 shows the switching position in the grounding device ON position. This position, as is also the case for any other position, can be inspected in the manner described. In this case, this switching position and the possibility for visually inspecting this position according to the invention is of considerable importance in terms of safety.
