Definitions
- the invention relates to an encapsulated, pressure-resistant executed, non-hermetically sealed, rotationally symmetrical high-performance spark gap with two opposing main electrodes, a cylindrical metallic outer housing, optionally a trigger electrode and electrical connection contacts for the main electrodes according to the preamble of patent claim 1.
- surge arresters on the basis of spark gaps according to the prior art, these are designed to be encapsulated in applications in the low-voltage range in order to avoid the environment-threatening blowing out of hot or even ionized gases.
- the arresters are provided with additional triggering devices.
- a trigger device requires isolation of the additional, generally loaded with high voltage further electrode.
- the additional expenditure of space and the additional insulation materials also lead to a further limitation of the performance of such realized arrester.
- the potential of the ignition electrode is likewise supplied via the pressure-resistant metallic sheath to the spark gap.
- the local pressure-resistant jacket is made of one piece and it is used for the preparation of a simple forming process.
- the waiver of an insulated implementation of the ignition potential leads in this variant, however, to an additional burden of insulation in the interior of the spark gap, since both electrodes must be isolated not only against each other, but also with respect to the entire housing.
- the complex and voltage-resistant insulation in particular, the heat output from the spark gap This leads to an increased thermal load on the insulating parts, to long cooling times and to an enormous limitation of the space available for the spark gap. All of these disadvantages ultimately limit the performance of the spark gap.
- the cylindrical outer housing is provided with at least one radially oriented opening in the form of a bore or recess, through which an electrical access to at least one of the electrodes located in the interior is provided. This may be at least one of the main electrodes and / or an access for a possibly necessary or intended trigger or ignition electrode.
- an electrically insulated contact element In the bore or recess then an electrically insulated contact element, the respective opening sealing, insertable.
- the electrically insulated contact element is therefore in non-conductive connection to the preferably metallic outer housing.
- the spark gap can be mounted with the rotationally symmetrical parts and the metallic outer casing is kept tight and mechanically stable by crimping.
- This tapping then ends either at the respective electrode or at a ausgestaltend provided conductive or semiconductive annular support member.
- This supporting element can, for the purpose of contacting with a trigger electrode in connection, be realized, and is arranged in the interior of the outer housing, wherein the annular support member is in the space between the main electrodes, embedded in an insulating material.
- the outer wall of the annular support member is substantially parallel to the housing wall running.
- the opening is performed as a bore at least to the surface of the outer wall of the annular support member.
- the annular support member increases the compressive strength of the overall arrangement in the region of the radially oriented opening or bore and at least compensates for the resulting weakening of the outer housing.
- the metallic outer housing is formed in two parts screwed, wherein in at least one of the outer housing halves, the recess for electrical contacting is. This recess accommodates an insulating insert and the necessary electrical contact element.
- a conductive annular support member standing in connection with the trigger electrode, arranged inside the outer housing, wherein the annular support member in the space between the main electrodes, embedded in an insulating material, and the recess is the desired Ensures access to the outer wall of the annular support member.
- Fig. 1 shows an embodiment of the encapsulated, flameproof, non-hermetically sealed, rotationally symmetric high-performance spark gap with one-piece outer casing and radially oriented opening in the form of a bore for contacting a trigger electrode and
- Fig. 2 is a view similar to that of FIG. 1, but starting from a two-piece, bolted metallic outer housing.
- the spark gap shown in the schematic diagram in section according to FIG. 1 has a rotationally symmetrical structure, wherein after the assembly of the spark gap, the cylindrical outer housing 1 is drilled radially laterally with a defined drilling depth. This tapping ends at an annular support member 12 which is electrically connected to the trigger electrode 6.
- the annular support member 12 is isolated from the main electrodes 2 and 3 and the outer casing 1 of the spark gap.
- the insulation on the metallic contact 13 can additionally be glued if necessary and sealed in this way.
- the hole can also be made before mounting in the outer housing 1, but here increases due to the positional dependence of the assembly effort.
- the adjacent insulating parts then have in this embodiment to the inner metallic contact an opening which z. B. in axially symmetric parts as a circumferential gap or in an asymmetrical isolation part as a bore executable (not shown).
- the main electrodes 2 and 3 are held in the embodiment of FIGS. 1 and 2 via insulating bushings 4 and 5 and have a protruding, outwardly oriented extension for electrical contacting.
- the outer housing has a one-sided completely closed bottom, wherein one of the main insulated electrodes located on the bottom inside and can be electrically connected by a lateral, radially oriented opening instead of the usual frontal contact-.
- FIG. 2 According to the illustration of FIG. 2 is assumed by a two-part outer casing 1.1 and 1.2, which is indirectly connected by a suitable thread directly or with the aid of a cap sleeve by screwing.
- a recess 15 is introduced, which is placed so that the insulated electrical contact 13 can be carried out, which in turn is connected to the annular support member 12 and via this support member 12 with the trigger electrode 6 in connection.
- the insulation for the electrical contact element 13 may be embodied here as a two-part insulating piece, which at the same time fixes the support element 12 and the trigger electrode 6.
