Definitions
- the invention relates to a shielding electrode which can be connected to an electrical device.
- Such a shielding electrode is known from German utility model DE 80 34 443 Ul.
- a frame-like shielding electrode is arranged on an outdoor high-voltage circuit breaker.
- several tabs are attached to it.
- the tabs each have recesses with which the shielding electrode can be fastened to the outdoor high-voltage circuit breaker, for example by means of screws or rivets.
- the invention has for its object to provide a shielding electrode of the type mentioned in such a way that a simplified assembly of the shielding electrode is made possible.
- the object is achieved according to the invention in the case of a shielding electrode of the type mentioned at the outset in that the shielding electrode can be connected to the electrical device by means of a latching connection.
- Snap connections have the advantage that they can be assembled without the use of additional tools. With a corresponding design of the latching connection, such ge connections sufficiently mechanically resilient.
- connection of a shielding electrode to an electrical device can be carried out in an extremely short assembly time.
- latching connections also enable the shielding electrode to be aligned to a sufficiently large extent with respect to the electrical device.
- simplified mounting of the often large-volume shielding electrodes is made possible.
- latching connection has an elastically resilient latching lug.
- Resilient locking lugs snap onto a profiling in a very simple manner.
- the profiling can be selected such that the latching lug can be fixed in several areas of the profiling. This enables the position of the shielding electrode to be adjusted relative to the electrical device during assembly.
- Lugs can be designed in such a way that they can only be snapped onto a special profile in a single snap-on direction. Without the use of tools, a reversal of the snap-on movement is not easily possible. This ensures a self-locking connection between the shielding electrode and the electrical device.
- the locking lug is arranged on a tongue.
- the resilient properties of the locking lug can be additionally supported by arranging the locking lug on a tongue. Furthermore, a corresponding, in particular elastic design of the tongue can provide relief the locking lug are created by external forces acting on the shielding electrode or on the electrical device. As a result, the latch and thus also the latch connection is protected against excessive mechanical stress. Furthermore, the tongue can also be provided for arranging the latching lug in a special position.
- the tongue is arranged parallel to a section of the shielding electrode.
- a relatively long tongue can be used, but this only increases the contour of the shielding electrode to a small extent.
- a long, narrow tongue dampens relative movements from the shielding electrode and the electrical device.
- a further advantageous embodiment provides that the tongue has a longitudinal axis and the latching lug has a vertical axis and the longitudinal axis is arranged perpendicular to the vertical axis.
- the vertical arrangement of the two axes relative to one another enables particularly effective decoupling of the movements of the latch itself necessary for latching the latch and of the movements of the tongue for decoupling external forces.
- the configuration of the tongue and the latching lug can be chosen such that the tongue supports the movement of the elastically resilient latching lug when the latching connection snaps together.
- the longitudinal axis or the vertical axis can deviate from an ideal straight line and have, for example, a curvature.
- the latching lug and / or the tongue are / are attached to the shielding electrode.
- the attachment of the locking lug and / or the tongue to the shielding electrode makes it possible to arrange the locking connection on the shielding electrode in such a way that it lies in a dielectrically shielded area. Faulty assemblies are avoided, as a result of which the snap-in connection would possibly impair the field-homogenizing effect of the shielding electrode.
- the shielding electrode is essentially tubular with a slot breaking through the tube wall.
- a tubular design and perforation of the tube wall with a slot results in a reduction in the mass of the shielding electrode with a sufficiently strong shielding effect.
- the slot in the tube wall of the shielding electrode enables the shielding electrode shell to swing elastically. Furthermore, simple manufacturing methods for producing the shielding electrode can be used through such configurations.
- the latching lug and / or the tongue are / are attached to one of the edge sections of the shielding electrode that delimit the slot in the cross section of the shielding electrode.
- the edge portions of the shielding electrode which delimit the slot enable the latching lug or the tongue to be fastened to the shielding electrode in a simple manner.
- the edge sections represent a fixed reference point for fastening the latching lug or the tongue. They are easy to locate compared to the typically curved surface structures of a shielding electrode. Since the edge sections on the shielding electrode represent sections with a relatively inhomogeneous exterior, these sections are arranged in an area shielded by the shielding electrode itself. Because, as described above, it can advantageously be provided to also arrange the latching lug or the tongue in such a section, there are advantages with regard to a structurally simple design with a good shielding effect of the shielding electrode.
- the shielding electrode is a molded plastic part.
- Plastic molded parts can, for example, be composed of several sub-elements and be manufactured by pressing processes or casting processes.
- the design of the plastic molded part as a plastic cast part offers particular advantages with regard to simple manufacture and short assembly time, the shielding electrode being manufactured in one piece with all the necessary elements of the latching connection, such as latching lugs or tongues.
- the shielding electrode is arranged on a vacuum interrupter.
- vacuum interrupters which essentially have a cylindrical outer contour, have projections and edges at the joints. These projections and edges can, for example, be shielded by a shielding electrode.
- the shielding electrodes are fastened according to the invention in a particularly cost-effective and time-minimized manner.

- Such a vacuum holding tube 1 can be used, for example, as an interrupter unit in a high-voltage or medium-voltage circuit breaker.
- An annular first shielding electrode 5 and an annular second shielding electrode 6 are arranged radially around the circumferential surface of the vacuum interrupter 1.
- the two shielding electrodes 5, 6 are supported on the vacuum holding tube 1, which is an electrical device.

- other shapes can also be used for the design of the shielding electrodes, such as oval shapes or polygonal frame shapes.
- FIG. 2 shows a top view of the first shielding electrode 5.
- the shielding electrode 5 has three fastening points 7a, b, c on its inner radius.
- the attachment points 7a, b, c each have the same construction. As an example, the construction of one of the fastening points 7a will now be explained.
- the attachment point 7a is shown enlarged and detailed in FIG.
- the section of the first shielding electrode 5 shown in FIG. 3 is tubular in cross section, a slot 8 completely breaking through the tube wall along the circumferential surface of the tube.
- a first edge section 9 and a second edge section 10 are formed through the slot 8 in cross section.
- a first tongue 11 is arranged on the second edge section 10.
- the tongue 11 was integrally connected to the first shielding electrode 5 during a casting process.
- the tongue 11 extends into the slot 8 in a first section 11a and extends radially in the direction of the center of the annular first shielding electrode 5 in a second section 11b.
- a plurality of latching lugs 12a, b, c, d arranged.
- the detents 12a, b, c, d are held on one side at their base on the second section 11b of the first tongue 11.
- Each of the locking lugs 12a, b, c, d has an engagement behind.
- the locking lugs 12a, b, c, d form a group of locking lugs which are arranged at a distance from one another and form a circular circumferential contour. They are spaced apart such that each of the locking lugs 12a, b, c, d is elastically resiliently deformable at its free end.
- the locking lugs 12a, b, c, d can be passed through a circular recess in a holder which is fastened to the vacuum holding tube 1. During the passage, a resilient deformation of the locking lugs takes place, so that the circumference formed by the locking lugs 12a, b, c, d decreases as it passes through the opening.
- the opening is dimensioned such that when the catches 12a, b, c, d reach behind the catches, the catches 12a, b, c, d spring back into their starting position and fix the control electrode.
- FIG. 11 schematically shows the top view of the vacuum interrupter 1.

The further locking lugs of the fastening points 7d, e, f of the second shielding electrode 6 can be snapped onto a rigid body edge. Due to the elongated design of the second tongue 13, the support surface 15a is supported on the rigid body edge and the second tongue 13 deforms when the further latch 14 is snapped on, so that the further latch 14 can be locked in a spring-loaded manner. The recessed support surface 15b limits the deformation of the second tongue 13 during a locking process.
- each of the fastening points 7d, e, f of the second shielding electrode 6 Due to the interaction of the fastening points 7d, e, f of the second shielding electrode 6, each of the fastening points locks onto a rigid body edge, each fastening point preventing the other fastening points from slipping off the body edges assigned to them.
