Embodiment Construction

[0046] in accordance with figure 1 In the spark gap, active components and passive components are arranged inside the housing 1 .

[0047] Firstly, in order to form a pressure-resistant cooling chamber, an inner cup 14 is provided, which is surrounded by an outer cup 15 at intervals for maintaining the gas cooling channels 17 .

[0048] One of the main electrodes protrudes into the cavity interior of the cup 14 as the electrode of the hollow-cylindrical blow-out electrode 3 .

[0049] On the open side of the cup structure there is provided a support ring 12 which laterally surrounds the blow-off electrode 3 . The support ring 12 has external threads corresponding to the internal threads on the outer cup 15 (see figure 2 ).

[0050] Lateral air outlet openings 16 are provided on the outer cup 15 , wherein at least the aforementioned gas cooling channels 17 are formed between the inner cup 14 and the outer cup 15 , and at the outer cup 15 Another slit-shaped gas cooling cha...

Abstract

The invention relates to an encapsulated, flameproof, not hermetically sealed, rotationally symmetrical high-performance spark gap with two main electrodes spaced apart opposite each other, a metal outer housing, at least one trigger electrode, a gas or plasma cooling space, surrounded by the outer housing, and external electrical contacts for the main electrodes, preferably arranged on the end face. According to the invention, the cooling space comprises a coaxial arrangement of an inner cup and an outer cup, one of the main electrodes being formed as a hollow-cylindrical expulsion electrode and reaching into the inner cup. Also provided on the open side of the coaxial structure is a supporting ring, engaging laterally around the expulsion electrode. The supporting ring is connected to the outer cup in a flameproof manner, in particular with nonpositive and / or positive engagement. The outer cup of the coaxial arrangement has lateral gas outlet openings. Provided between the inner and outer cups there is at least one gas cooling duct. Between the outer wall of the outer cup and the inner wall of the outer housing there is a further, gap-like gas cooling duct. The gas cooling ducts themselves follow an altogether meandering path.

Description

technical field [0001] The invention relates to an encapsulated, pressure-resistant, non-hermetically sealed and rotationally symmetrical high-power spark gap, comprising two spaced and opposite main electrodes, a metal casing, at least one trigger electrode, a gas surrounded by the casing Or the plasma cooling chamber and the electrical connection contacts for the main electrodes, preferably arranged at the end sides. Background technique [0002] In the case of surge arresters based on spark gaps according to the prior art, the spark gaps are encapsulated in applications in the low-voltage area in order to avoid the environmentally hazardous blowing out of hot or still ionized gases. [0003] In blow-out arresters belonging to the earlier prior art, up to approximately 90% of the converted energy is mostly discharged into the environment in the form of hot gas. Obviously, both thermal and dynamic loads are increased for modern spark gaps due to avoiding blowout. For enca...
