Definitions
- the invention relates to a switching contact for Vaku ⁇ umschaltröhren according to the preamble of claim 1.
- Switching contacts for vacuum switching tubes are known from the prior art, which consist of a switching contact carrier and a contact plate, wherein the switching contact carrier a
- Coil segment for generating a magnetic field receives, which is formed by slotting the lateral border of the cup-shaped contact carrier.
- Such contact arrangements are described in particular in EP 0 104 384 B1 and EP 0 155 376 B1.
- a radial or an axial magnetic field is generated, in which case in particular those arrangements with an axial magnetic field are of importance for high voltages.
- the openings of the contact carrier in the two contacts are oriented identically.
- AMF Axial Magnetic Field
- the object of the invention is, by constructive improvements increase the efficiency of the contacts.
- the outer diameter of the slotted pot wall is smaller than the diameter of the contact plate located thereon.
- an annular support body i. an outer support body provided between the contact plate and the base of the contact carrier, i. the bottom of the pot, is inserted and surrounds the contact carrier zu ⁇ least in the slotted area.
- an improved switching contact is demoaf ⁇ fen, the net input in particular in vacuum interrupters with axial Mag ⁇ .
- the prior art does not disclose any suitable solution to the problem. If, in fact, the coil body is bordered by an externally circulating steel strip with only moderate conductivity, the previous production methods result in a deterioration of the switching capacity of typically about 30%, which leads to a considerable increase in size and thus more expensive vacuum interrupters.
- the cause of this deterioration of the switching capacity lies in the partial short circuit between the two coil segments separated by a slot caused by the steel strip, the short circuit being caused by the electrically intimate contact between the steel strip and the coil segments caused by the flow of good conductive solder during the soldering process or between two adjacent coil segments is caused.
- An inventive AMF contact with outer support body is made such that in the production between basedstütz redesign and bobbin a distance of typically one millimeter is maintained, and the outer support body is soldered only in its upper and lower edge regions with the contact system. At this gap width, a direct overlay bridges of the gap avoided by inflowing solder. If the bobbin widens in switching operation due to short-circuit disconnections, an electrical connection with only a low current-carrying capacity and comparatively high resistance forms between two coil elements, so that the contact only has a small decrease in the switching capacity due to the electrical shunt through the outer support itself learns.
- the outer support body is chosen from an electrically nonconductive material, for example made of ceramic, or a metallic outer support body is coated on its inside with a ceramic material, then the electric shunt is completely eliminated when the coil body is being widened and the ability to see is thereby eliminated not reduced.
- Figure 1 is a perspective view of an AMF contact pair according to the prior art
- FIG. 2 shows a section through a contact according to the invention with outer support body.
- FIG. 1 shows a contact pair arrangement 1 according to the prior art, which consists of two identical contacts 10, 10 '.
- the contacts 10, 10 'each have a contact pin 11, 11' a contact carrier 12, 12 'and a contact plate 15, 15'.
- the contact carrier 12, 12 'pot-shaped becamebil ⁇ det and has at its annular portion, which is referred to as pot wall 13, 13', straight or curved, azimuthally inclined slots 14, 14 '.
- the slots 14, 14 ' extend on the circumference of the pot wall 13, 13' from the base, ie the Topf ⁇ bottom, to the free end of the pot wall 13, 13 '.
- Coil segments are formed by the azimuthal slots 14, 14 ⁇ in the contact carrier 12, 12 ⁇ in which the current to be switched flows. Due to the switching current, a magnetic field is generated, which in the embodiment shown in Figure 1 orien- tation of the slots 14, 14 'is oriented in the same direction axially of the contact arrangement and te when opening the Kontak ⁇ 10 1NC ⁇ a diffuse arc causes which is indicated in the figure with LB lg.
- the slots 14, 14 ⁇ - in contrast to figure 1 - in bei ⁇ the contacts 10, 10 ⁇ against each other extend in a different direction, a radial magnetic field results zwi ⁇ rule the contacts 10, 10 ⁇ , which in this case a kontra ⁇ hierter arc on the contact plate 15, 15 ⁇ is driven to the outside.
- the slots in the contact plate may optionally be spiral-shaped.
- FIG. 2 a switching contact according to FIG. 1 is modified according to the invention. Similarly, a switching pin 21, a contact carrier 22 with an annular portion 23 as a cup wall and azimuthal slots 24 and a contact plate 25 with slots 26 are present. However, the pot wall 23 with the coil segments is offset inwardly in FIG. 2.
- the outer support body 20 is made of steel or the like
- the support body 20 can also consist of an electrically non-conductive material, for example of ceramic. It is also possible to coat a metallic ring on its inside with a ceramic material.
- the outer support body 20 has to be soldered into the "recess.” In this case, solder can penetrate into the slots 24 and thus cause a short circuit or partial short circuit, which leads to a reduction of the magnetic field and thus to a deterioration of the switching properties of the contact.
- the outer support body 20 be made so thin and inserted into the recess that a peripheral cavity 30 remains between the wall of the contact carrier 22 with the coil segments and the support body 20, which in the case of the intended use of the contact arrangement in a vacuum necktube Vacuum gap "realized.
- the vacuum gap 30 between the outer support body 20 and the coil segment prevents solder from penetrating during the soldering process into the azimuthal slots 24 or between adjacent slots 24 and the outer support body 20. It will achieved with a mechanically strong connection between theticianstweil- body 20 and the other justifyeilen, without it can come in the coil segments or between coil segments and ostweil redesign to well-conductive short circuits or Generalkurz- conclusions.
