Definitions
- the invention relates to an overvoltage protection device with a first spark horn having the first electrode, with a second spark horn second electrode, with an air breakdown spark gap effective between the spark horns and with a housing receiving the electrodes, the two spark horns being designed and arranged in relation to one another, that they diverge from a lower ignition area to their outer ends, so that the air breakdown spark gap starts from the ignition area expanded outside.
- At least one is an essential part of a surge protection device Spark gap that responds to a certain overvoltage, the response voltage and thus prevents that by such a surge protector protected area overvoltages occur that are greater than the pickup voltage the spark gap are.
- the surge protection device according to the invention two electrodes and one between the electrodes or their spark horns effective air breakdown spark gap.
- surge protective devices with an air breakdown spark gap there are surge protective devices with an air flashover spark gap in which a sliding discharge occurs when activated.
- Surge protection devices with an air breakdown spark gap have overvoltage protection devices with an air flashover spark gap the advantage of a higher one Surge current carrying capacity, but the disadvantage of a higher one - and not particularly constant - response voltage. Therefore there are already various surge protection devices proposed with an air breakdown spark gap which have been improved in response voltage.
- Air breakdown spark gaps have been realized in various ways, e.g. B. such that at least one sliding discharge between the spark horns triggering ignition aid has been provided, partially in the air breakdown spark gap protrudes, is web-like and made of plastic.
- An overvoltage protection device from which the invention is based is already out known from DE 44 02 615 C 2.
- the well-known surge protection device has two narrow electrodes, which are each angular and each have a spark horn and an angled connecting leg.
- the known surge protection device is characterized in that it due to the electrodes extending virtually in one plane, only a small one Has width.
- the known surge protection device has in any case a high surge current carrying capacity and a high one at the first response Line follow current extinguishing capacity. Problems always arise when there is a problem Arc seizes in one place, causing damage to the electrodes can.
- an overvoltage protection device is known from DE 196 04 947 C 1, which is essentially rotationally symmetrical.
- the two electrodes are identical and each have truncated cone-shaped spark horns, whereby an ignition bridge between the two facing ends of the spark horns to trigger a sliding discharge.
- This well-known surge protection device is also characterized by a high surge current carrying capacity and a high follow-up current extinguishing capacity.
- the disadvantage is that the known surge protective device has a relatively large overall height. Another The disadvantage is that when the spark gap is triggered, it is considerable Forces act on the extremely sensitive ignition bridge, causing damage to the Ignition bridge can lead.
- the object of the present invention is therefore an overvoltage protection device of the type in question to indicate the smallest possible height due to a high surge current carrying capacity and a high follow-up current extinguishing capacity distinguished.
