Definitions
- the invention relates to an overvoltage protection element for the derivation of transients Overvoltages, with two in parallel each having a power connection electrodes arranged side by side and next to each other, one between the electrodes effective air breakdown spark gap and a receiving the electrodes Casing.
- Such an overvoltage protection element is e.g. B. from the DE 919 056 C known.
- Surge protection elements with an air breakdown spark gap and side by side lying electrodes are also from FR 2 389 944 A, the US 3,878,423 and known from US 3,450,923. According to US 3,878,423 Electrodes arranged one behind the other.
- surge protection element by which the invention is based on, i.e. one with an air breakdown spark gap, there are surge protection elements with an air flashover spark gap, in which a sliding discharge occurs when activated (cf. DE 27 18 188 A1, DE 29 34 236 A1 and DE 31 01 354 A1).
- Surge protection elements of the type from which the invention is based that is to say those with an air breakdown spark gap, have overvoltage protection elements with an air flashover spark gap the advantage of a higher surge current carrying capacity, however, the disadvantage of a higher - and not particularly constant - response voltage.
- each electrode has a connection leg and spark horn running at an acute angle to the connecting leg and form the spark horns of the two - spaced apart - Electrodes together form the air breakdown spark gap. It is between the opposite ends of the connecting legs of the two electrodes one - a sliding discharge triggering ignition aid is provided.
- DE 44 02 615 A1 that it is advantageous if the spark horns of the Electrodes in their areas adjacent to the connection legs with a bore are provided.
- the above-mentioned surge protection element known from DE 44 02 615 A1 is carried out in practical implementation so that it has a surge current carrying capacity of 100 kA, on the other hand to delete network follow currents is suitable in the range of 100 A.
- the invention is based on the object of an overvoltage protection element Provide generic type that is simple and inexpensive to build on is easily adaptable to different requirements in its manufacture and is still functional even after multiple responses.
- the surge protection element according to the invention is now characterized in that that the electrodes have different cross sections over their length.
- the electrodes can be cylindrical and a circular one have oval and / or a rectangular cross section.
- Different cross sections means not only a difference in geometry, i.e. circular, oval or rectangular, but also in dimensions; the electrodes can be graduated in length across its length so that the area known as the air breakdown spark gap should be effective, specified in a special way locally can be.
- the interior of the electrode receiving Housing is lined, the lining preferably made of POM-Teflon consists.
- the surge protection element according to the invention serves to derive transient overvoltages and to limit surge currents, in particular of lightning impulse currents, as well as for the deletion of network follow currents; lightning impulse currents up to 100 kA can be derived and line follow currents from typically 3 to 4 kA, maximum of 25 kA or even 50 kA, can be deleted.
- the surge protection element according to the invention consists in its essential Construction from two electrodes 3, 4, each having a current connection 1, 2 between the electrodes 3, 4 effective air breakdown spark gap 5 and one the electrodes 3, 4 housing 6.
- the electrodes 3, 4 are arranged parallel to one another.
- the Electrodes 3, 4 are arranged side by side; their longitudinal axes therefore fall apart.
- the electrodes 3, 4 are cylindrical; they have a circular cross section.
- Electrode sections 3c and 4c the largest diameter. Between the electrode sections 3c and 4c is therefore the smallest distance, so that between the Electrode sections 3c and 4c formed the air breakdown spark gap 5 is.
- the power connections could both electrodes are on the same side.
- the power connections 1 and 2 of both electrodes 3 and 4 are located on opposite sides. They run as is easily taken from the figures can be parallel to each other. However, exemplary embodiments are also conceivable, where the power connections of both electrodes are at an acute angle to each other.
- the interior of the the electrodes 3, 4 housing 6 is lined, the liner preferably consists of POM-Teflon.
- an overvoltage protection element according to the invention shown in the figures is a particularly advantageous one in that the electrodes 3, 4 receiving housing 6 is closed and pressure-resistant.
- the Printing cylinder 10 has a printing sleeve 11, the printing sleeve 11 on one side with an external thread 12 and on the other side with an inwardly projecting Flange 13 is provided, a union nut 14 is provided and the union nut 14 is screwed onto the pressure sleeve 11.
- the manufacture of the surge protection element according to the invention that is Manufacture of the individual parts and the assembly of these individual parts is pronounced simple and therefore inexpensive.
- the electrodes 3, 4, the individual parts of the housing 6, namely the housing jacket 7 and the Housing flanges 8, 9, and the individual parts of the outer pressure cylinder 10, that is the pressure sleeve 11 and the union nut 14 are rotationally symmetrical Parts that are either readily available or as turned parts modern machine tools can be mass-produced.
- each housing flange 8, 9 is both with a Through hole 15, 16, as well as provided with a blind hole 17, 18.
- the so trained housing flanges 8, 9 thus allow both the passage of Power connections 1, 2, and - on the other side - an end bearing of the electrodes 3, 4, namely in the area of the electrode sections 3e, 4e.
- an inventive Overvoltage protection element applies that the housing flanges 8, 9 sealing can be clamped against the cylindrical housing shell 7, with Help of the outer pressure cylinder 10, namely in that the union nut 14th is screwed onto the pressure sleeve 11.
- the housing 6 receiving the electrodes 3, 4 can have air as the extinguishing gas; however, it can also be provided with another known extinguishing gas, for example SF 6 . Otherwise, the extinguishing gas in the electrodes 3, 4 receiving housing 6 are at atmospheric pressure, but is also conceivable, in the embodiment described, in which the electrodes 3, 4 receiving housing 6 is pressure-tight and pressure-resistant that the extinguishing gas is at a pressure deviating from the atmospheric pressure.
