Abstract
The invention relates to a spark gap arrangement for use in power supply systems, especially in low-voltage systems, comprising an arcing chamber in which an electric arc is formed between two electrodes of the spark gap. An intermediate chamber (5) is provided downstream of the arcing chamber (3). Said intermediate chamber has a much greater volume than the arcing chamber (3). A pressure-proof flow channel (4), preferably consisting of metal, is provided as the connection between the arcing chamber (3) and the intermediate chamber (5).
Claims14
An encapsulated spark gap arrangement for use in power supply systems, including low-voltage systems, having an optimized ability to extinguish system secondary currents, said encapsulated spark gap arrangement comprising:
- an arcing chamber having a spark gab and at least two electrodes between which arcing occurs;
- and
- an intermediate constant-volume chamber disposed downstream of the arcing chamber and connected thereto by a metallic flow channel, wherein a volume of said intermediate chamber is substantially larger than a volume of the arcing chamber.
An encapsulated spark gap arrangement for use in power supply systems, including low-voltage systems, having an optimized ability to extinguish system secondary currents, said encapsulated spark gap comprising:
- an arcing chamber, within which arcing occurs between two electrodes in the spark gap, wherein downstream of the arcing chamber there is disposed an intermediate chamber, a volume of which is substantially larger than a volume of the arcing chamber itself, and wherein there is further provided a pressure-resistant, metallic flow channel to connect the arcing chamber to the intermediate chamber, and
- the walls of the intermediate chamber are covered on their inner surfaces with a plastic that gives off a quenching gas when heated.
An encapsulated spark gap arrangement for use in power supply systems, including low-voltage systems, having an optimized ability to extinguish system secondary currents, said encapsulated spark gap comprising:
- an arcing chamber, within which arcing occurs between two electrodes in the spark gap, wherein downstream of the arcing chamber there is disposed an intermediate chamber, a volume of which is substantially larger than a volume of the arcing chamber itself, and wherein there is further provided a pressure-resistant, metallic flow channel to connect the arcing chamber to the intermediate chamber, and
- a flow channel projects into the intermediate chamber and guide means are provided therein to divert the gas flow.
An encapsulated spark gap arrangement for use in power supply systems, including low-voltage systems, having an optimized ability to extinguish system secondary currents, said encapsulated spark gap arrangement comprising:
- an arcing chamber having a spark gap and at least two electrodes between which arcing occurs;
- and
- an intermediate chamber having a continuously opened outlet opening, said intermediate chamber being disposed downstream of the arcing chamber and connected thereto by a metallic flow channel, wherein a volume of said intermediate chamber is substantially larger than a volume of the arcing chamber.
