Embodiment Construction

[0039] figure 1 One of the half shells is shown, which is designed as an injection-molded part 2 with an outer insulating material sheet 23 , for example in the form of a vulcanized fiberboard. Also visible is a ferromagnetic plate-like part 21 , which is covered by an inner vulcanized fiber plate 20 .

[0040] In the representation of the half-shells 22 , profiles can also be seen which are adapted to the contour of the ferromagnetic material 21 , which also applies to the inner vulcanized fiberboard 20 .

[0041] Holes visible in the outer vulcanized fiberboard 23 receive rivets that connect the two half-shells of the housing and the elements located therein.

[0042] in accordance with figure 2 The basic structure of an angular spark gap module can be seen in the illustration in , the arc chamber of which is influenced by two electrodes 1 and 2 .

[0043] Electrode 1 is designed as a long electrode and electrode 2 as a short electrode.

[0044] The area of ​​the arc ru...

Abstract

The invention relates to a horn spark gap with a deion chamber (8) with a non-blowout design having a multi-part insulating housing as supporting and accommodating body for the horn electrodes (1, 2) and the deion chamber (8) and means for conducting the arc-induced gas flow, wherein the insulating housing is divided in the plane spanned by the horn electrodes and forms a first and a second half-shell. According to the invention, the horn electrodes (1, 2) have an asymmetrical form. The arc running region (11) between the electrodes is delimited in the direction of the deion chamber by a plate-shaped insulating material (20), wherein the plate-shaped insulating material (20) is inserted into a respective first shaped portion of the respective half-shell in a form-fitting manner. Furthermore, the first shaped portions accommodate a ferromagnetic deposit (21) of the arc running region (11), wherein the plate-shaped insulating material (20) electrically isolates the respective deposit from the electrodes (1, 2). The half-shells also have further, second shaped portions, which engage around an insertable deion chamber part (8) in a form-fitting manner, wherein apertures or openings in the respective half-shell are located between the respective first and second shaped portions, and the shorter (2) of the electrodes ends in front of the deion chamber part (8), with the result that the gas flow only passes partially into the deion chamber.

Description

technical field [0001] The invention relates to an angular spark gap with a deion chamber in a non-exhaust construction according to claim 1, comprising a multi-piece housing of insulating material as support and receiver for the angular The electrodes and the deion chamber as well as the guide elements for the arc-induced gas flow, the insulating material housing are split in the plane formed by the angular electrodes and form the first and second half-shells. Background technique [0002] Angular spark gaps are known from EP1914850B1 and EP1829176B1, in which the degassing effect of ionized gases is reduced. [0003] According to EP1914850B1, the horn electrodes are made of inexpensive materials in order to reduce the cost of producing such spark gaps. [0004] Furthermore, EP1829176B1 discloses a device for extending a separation path in the event of overload. [0005] Furthermore, solutions with angular spark gaps and non-hermetic packaging are known, in which self-mag...
