Definitions
- the invention relates to a device for gas-tight implementation of a conductor through a housing wall according to the preamble of claim 1.
- Gas-insulated switchgear often have components that require in addition to the high-voltage bushing another implementation for a ground connection or monitoring devices. Such a component is for example
- Surge arrester whose earth line is to be monitored for occurring leakage currents.
- Such a passageway directs a conductor from within a gas-tight housing to the outside, wherein the conductor must be electrically isolated from the housing. Since the voltages occurring here are low, two insulated sockets, which are arranged on a housing opening inside or outside the housing, are often sufficient as feedthroughs. The conductor is from the inside through the inner socket, non-contact through the
- Object of the present invention is a device for gas-tight implementation of a conductor by a
- a device for gas-tight implementation of a conductor through a housing wall in particular a
- the outer insulating bush is fixed in a rotationally fixed manner in a recess of the housing wall with respect to the bushing axis. This can be achieved, for example, by arranging bulges on the housing-side end face of the outer insulating bushing, such as pins in the direction of the bushing axis, which engage in corresponding indentations in the outside of the housing. If a mounting nut on the inside of the housing is screwed onto the conductor during assembly of the device, so the insulating bushing can not rotate and therefore does not need to be held with a tool, which facilitates assembly.
- the recess in the housing wall and at least one protruding into the recess portion of the outer insulating bushing congruent and with respect to the feedthrough axis not rotationally symmetrical cross sections.
- the insulating bush could be cylindrical and have a polygonal cross-section with three, four or six preferably rounded corners.
- the recess in the housing wall then has a corresponding cross-section, so that the outer insulating bush can partially dip into this depression. Due to the polygonal cross-section, the outer insulating bushing is fixed so that it is rotationally fixed with respect to rotations about the feedthrough axis.
- the anti-rotation protection is achieved by a correspondingly shaped outer contour of the outer insulating bush, no devices on the front side are necessary. If the front side of the outer insulating bushing is flat and rests flat on the housing wall within the recess, a reliable seal is particularly easy to achieve. In addition, the insulating bush is particularly easy to produce.
- the conductor has a stop, which, for example positive fit, in a corresponding recess of the outer insulating bush with respect to the feedthrough axis
- the abutment could be a round, in relation to the feedthrough axis radial, provided with one or more flattened sides molding in the region of the housing outer side end of the conductor.
- the recess is formed in the housing outer side end of the outer insulating bushing accordingly.
- the stop serves on the one hand as a depth stop for the conductor, on the other hand as anti-rotation, so that when mounting on the
- Figure 2 is a view of a device according to the invention from the outside of the housing.
- FIGS. 1 and 2 show part of a housing wall 1 of a component of a gas-insulated switchgear, for example a gas-insulated surge arrester.
- a gas-insulated switchgear for example a gas-insulated surge arrester.
- an outer insulating bushing 4 and this opposite to the inside of the housing 14 an inner insulating bushing 3 are arranged on the housing outer side 13, so that there is a through opening through the two insulating bushes 3, 4 and the housing wall 1.
- a conductor 5 is inserted.
- Two nested insulating tubes 10 connect through the housing opening 17 the Both insulating bushes 3, 4 and serve the increased insulation strength between the conductor 5 and the housing wall 1.
- the conductor 5 is designed in the manner of a cylindrical bolt which carries on the housing inner side 14 a thread for a fastening nut 16, and on the housing outer side 13 a Stop 7, the flat on the housing wall 1 facing away from the outer insulating bushing 4 rests.
- the cylinder axis of the conductor 5 defines a passage axis 15 between the stopper 7 and the outer insulating bushing 4, an annular seal 12 is inserted.
- the inner insulating bushing 3 is substantially a hollow cylinder, here shown with a circular base surface, which abuts with a front side on the housing inner wall 14.
- the outer insulating bush 4 is also hollow cylindrical, but has a non-rotationally symmetrical cross-section. Shown here is a square section with rounded corners. However, the cross section could also be polygonal, for example, triangular or hexagonal or even have an oval shape.
- the housing outer side 13 has around the housing opening 17 a recess 6, which can be prepared for example by milling.
- the recess 6 corresponds in its cross section to that of the outer insulating bushing 3, so it is congruent to this, so that the outer insulating bushing 3 can be inserted into this recess 6 partially.
- outer insulating bushing 4 The housing-side end face of the outer insulating bushing 4 is then flat against the housing wall 1, and is sealed against this with an annular seal 11. Due to the non-rotationally symmetrical cross sections of outer insulating bushing 4 and recess 6, the outer insulating bushing in the recess 6 is rotationally fixed relative to a rotation about the bushing axis 15.
- the stop 7 of the conductor 5 is arranged in the region of the housing-outside end of the conductor 5 circular disk-like Anformung with two flattened sides.
- the outer insulating bush 4 has on its side facing away from the housing wall 1 end a recess on 8, the stop 7 form- conclusively absorbs.
- the positive connection is given here by the two flat sides of the stop, which abut against two flat side walls of the recess 8, which are shown like a nose here.
- the stopper 7 and thus the conductor 5 are thus fixed against rotation in the outer insulating bushing 4 against the passage axis 15. Via a connecting pin 9, a ground cable or other electrical line to the conductor 5 can be connected.
- the installation of the device is preferably carried out in a housing cover which is placed after the installation of the device on the housing.
- an insulating tube 10 is first inserted into the outer and the inner insulating bushing 3, 4 and fixed there, for example by means of an adhesive. Then, the outer insulating bushing 4 is inserted from the housing outer side 13 in the recess 6 of the housing wall 1, wherein the insulating tube 10 is inserted through the housing opening 17. The attached to the inner insulating bushing 3 insulating tube 10 is inserted from the inside of the housing 14 through the housing opening 17 into the outer insulating bushing 4. The conductor 5 is now inserted from the outside of the housing 13 in the outer insulating bush 4, passed through the insulating tubes 10 and the housing opening 17 and finally through the inner insulating bushing 3 to the inside of the housing 14. The stopper 7 is then in the recess 8 of the outer insulating bushing 4. From the
- a fastening nut 16 is screwed onto the conductor 5 and tightened with a tool so far that the seals 11, 12, the housing inner side 14 against the housing outer side 13 seal. Since the outer insulating bushing 4 in the recess 6 of the housing wall 13 and the conductor 5 are fixed against rotation with the stopper 7 in the recess 8 of the outer insulating bushing 4, when tightening the fastening nut 16, neither the conductor 5, nor turn the outer insulating bush 4 with you. A counter with other tools is therefore not necessary.
