Problems solved by technology

[0007] The solutions described above are limited in terms of the smallest possible installation space due to the cylindrical structural shape of the surge arrester and the required minimum diameter
[0008] Furthermore, the known housing arrangements are not suitable for accommodating angular gap arresters, from which the gases caused by the arc flow out in cooled form for pressure equalization

Embodiment Construction

[0031] The housing arrangement shown in the figures is based on a base part 1 which accommodates a plurality of individual modules 2 with lightning arresters located thereon.

[0032] like figure 2 and 3 It can be seen that the individual modules are arranged in the base part 1 in parallel and adjacently.

[0033] The single module 2 (with corner gap arrester and whose insulating material half-shell 3 has a cooling space for the gas caused by the arc) also comprises an outflow 4 in the form of a small opening.

[0034] exist figure 1 and 2 Outgassing, ie, the path of flowing gas or particles caused by burnout or arcing, is indicated by arrows in .

[0035] The particle or gas flow is deflected several times through the pressure equalization chamber 5 and the aperture 6 .

[0036] Aperture 6 in figure 1 is arranged in the region of the latching device 7 for mounting rail mounting. exist figure 2 In this case, the opening runs along a slot visible in the drawing in the...

Abstract

The invention relates to a housing assembly for multi-pole surge protection devices, comprising a base part (1), which receives individual modules (2) provided with electrical outside connections, wherein at least one individual module (2) comprises a horn gap and each individual module (2) consists of insulating material half shells, which encapsulate the respective spark gap, and at least the individual module (2) comprising the horn gap comprises a cooling space for electric arc-related gases between the insulating material half shells. Moreover, a shrouding cover (8) is present, which encloses the individual modules (2) and, on the assembly side, is positively and / or non-positively connected to the base part (1), wherein the shrouding cover (8) comprises windows (10) for a function display of the individual modules (2) in the upper cover face. According to the invention, first insulating material partitions (14), which extend from the bottom upward, are designed in the base part (1) and connected thereto, wherein said partitions delimit respective chambers for the individual modules. Second insulating material partitions (15), which extend in the direction of the base part (1), are designed in the shrouding cover (8) and connected thereto, the locations and positions of said partitions being complementary to the first insulating material partitions (14) so as to form the chambers.

Description

technical field [0001] The invention relates to a housing arrangement for a multi-pole overvoltage protection device according to the preamble of claim 1, comprising a base part that accommodates individual modules provided with electrical external connections, wherein at least one of the individual modules has an angular gap arrester and each single module has insulating material half-shells enclosing the corresponding surge arrester and at least the single modules with angular gap arresters have between the insulating material half-shells for the gas caused by the arc In addition, it includes a cover, which surrounds the single module and is positively and / or non-positively connected to the base part on the installation side, the cover having a function display for the single module on the upper side of the cover window. Background technique [0002] DE 101 25 941 B4 discloses a compact arrangement for a multi-pole surge current-resistant surge arrester comprising interna...
