Claims

The mast switch is a well-known device for disconnection in the operation of overland networks of the overhead lines.

The older designs were not able to cope with larger disconnection capacities, and the separation was therefore generally carried out without current. Lately the switches have become essential improved and suitable for switching off larger services. Therefore one tries also to use the switches in a similar way to the oil switches. One sees the switches with automatic release for this purpose. The particular advantage of such Switch is that you can selectively separate defective stub lines from the main lines.

The triggers for such switches were based on older switch designs generally built on fixed column insulators. On these column insulators It is not uncommon for the contact springs for the switch blades to be attached. In some In some cases, these insulators were also used to tension the outgoing lines.

These constructions were, apart from the arrangement of the release, not very reliable, and therefore today we have moved on to arrange the switching insulators α on both sides according to the drawing and to tension the outgoing lines b on chain insulators d . With these newer switch designs it is no longer possible to arrange the release on the switch isolator.

The aim of the present invention is to enable automatic triggering for mast switches of this arrangement as well. For this purpose, according to the drawing, the release c is designed as a tensioning element and suspended from the chain (stick) insulator d which is used to tension the lines. The trigger pulse is transmitted to the switch lock g by a linkage e on an insulator /, which takes account of the changes in position of the release caused by the cable fluctuations.

A special embodiment of this release consists in that the release device and the release coil are encapsulated in a special housing h and this housing is inserted into a second outer housing / which in turn is designed as a tensioning element. This enables easy replacement of the internal release parts for the purpose of revision and the like, without any work having to be carried out on the line itself.
