Definitions
- the invention relates to an overvoltage protection element for the derivation of transients Surge voltages, with two, each having a power connection, in parallel electrodes arranged to each other, an air breakdown spark gap effective between the electrodes and a housing accommodating the electrodes, wherein the housing housing the electrodes is closed and pressure-tight and pressure-resistant is executed and a cylindrical housing shell and two each on one Has provided housing flanges at the end of the housing shell.
- Such one Surge protection element is e.g. B. known from DE 919 056 C.
- overvoltage protection element from which the invention is based, one those with an air breakdown spark gap, there are surge protection elements with an air flashover spark gap, so when responding a sliding discharge occurs (cf. DE 27 18 188 A1, DE 29 34 236 A1 and DE 31 01 354 A1).
- Surge protection elements of the type on 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 one - and not particularly constant - response voltage.
- each electrode has a connection leg and one at an acute angle to the connecting leg Spark horn and form the spark sparks of the two - at a distance from each other arranged - electrodes together the air breakdown spark gap. It is between the opposite ends of the connecting leg an ignition aid, which triggers a sliding discharge, is provided for both electrodes. additionally can be seen from DE 44 02 615 A1 that it is advantageous if the spark horns of the electrodes in their adjacent to the connecting legs Areas are provided with a hole.
- the above-mentioned surge protection element known from DE 44 02 615 A1 is carried out in practical implementation so that on the one hand there is a Has a surge current carrying capacity of 100 kA, on the other hand to extinguish line 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 first and foremost characterized in that the housing in an outer pressure cylinder is arranged.
- the surge protection element according to the invention serves to derive transient overvoltages and to limit surge currents, especially 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 of 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 receiving housing 6 is lined, the lining 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 housing 3, 4 receiving the electrodes 6 consists of a cylindrical Housing shell 7 and two each at one end of the housing shell 7 provided housing flanges 8, 9.
- 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, the Manufacturing of the individual parts and the assembly of these individual parts is out of the question simple and therefore inexpensive.
- 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 with both 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.
