Embodiment Construction

[0035] figure 1 A surge arrester 1 for a surge protection device (not shown) is shown. The surge arrester 1 has a housing 2 which is formed from a plurality of housing parts 3 , 4 . An arc combustion chamber 5 is formed in the housing 2 . Furthermore, the surge arrester 1 has three electrodes 6 , 7 , 8 . A first spark gap 9 is formed between the first electrode 6 and the second electrode 7 . A second spark gap 10 is formed between the second electrode 7 and the third electrode 8 . Overall, thus two spark gaps 9 , 10 are realized with three electrodes 6 , 7 , 8 . A compact construction of the surge arrester 1 with two spark gaps 9 , 10 is thereby achieved. When the first spark gap 9 is ignited, a first arc is generated between the first electrode 6 and the second electrode 7 . When the second spark gap 10 is ignited, a second arc is generated between the second electrode 7 and the third electrode 8 .

[0036] as in Figure 4 As can be seen in , the surge arrester has fo...

Abstract

The invention relates to a surge arrester for an overvoltage protection device, which has a housing, an arc combustion chamber formed in the housing, two electrodes formed between each two electrodes spark gaps, wherein an arc is generated between two electrodes of the spark gap when one of the spark gaps is ignited. The object of providing a surge arrester which can be produced more compactly and cost-effectively than the surge arresters known from the prior art is solved in that the surge arrester has a total of three poles, Wherein, the first spark gap is configured between the first electrode and the second electrode and the second spark gap is configured between the second electrode and the third electrode, so that when the first spark gap is ignited, the first electrode and the second electrode A first arc is generated between the second spark gap and a second arc is generated between the second electrode and the third electrode upon ignition of the second spark gap.

Description

technical field [0001] The invention relates to a surge arrester for an overvoltage protection device, which has a housing, an arc combustion chamber formed in the housing, two sparks formed between every two electrodes gaps, wherein an electric arc is generated between two electrodes of the spark gap when one of the spark gaps is fired. Background technique [0002] A large number of mentioned surge arresters with spark gaps are known from the prior art and are used for protecting electrical circuits or devices and lines against overvoltages. An essential component of the mentioned surge arrester is at least one spark gap, which responds to a certain overvoltage (the so-called response voltage). If the spark gap ignites, an arc is generated between the two electrodes of the spark gap, and an inrush current is conducted via the surge arrester. This prevents the occurrence of overvoltages in the circuit protected by the surge arrester which are greater than the response vol...
