Definitions
- the invention is based on a gas pressure switch according to the first part of claim 1.
- Such a switch is described in EP-A-0 173 804.
- the known switch has an insulating gas-filled housing with two contact pieces located inside the housing and movable along an axis relative to one another.
- the power connections of this switch enter the interior of the housing diametrically to the axis and are guided there to the contact pieces transversely to the axis.
- a secure current transfer from the power connection to the fixed contact piece is achieved by two half-shells forming the fixed contact piece and spaced apart from one another along a parting plane, and by two flat rails arranged parallel to one another and guided as a power connection to one of the two half-shells.
- the invention as characterized in claim 1 solves the task of simplifying the gas pressure switch of the generic type while maintaining a safe current transfer from the power connection to the fixed contact piece.
- the pressure gas switch according to the invention is characterized in that its contact system is simple in construction and can be exchanged without problems. At the same time, it is achieved in a simple manner that, regardless of the current to be conducted, there are always safe current transitions from the power connection to the fixed contact piece and from the fixed contact piece to the movable contact piece. Additional contact springs can therefore be extremely weak.
- the compressed gas switch shown in FIG. 1 has a housing 1 filled with insulating gas, such as sulfur hexafluoride, at a pressure of a few bar.
- insulating gas such as sulfur hexafluoride
- bushings 2 and 3 are provided, through which a power connection 4 or 5 for a cylindrical contact piece 7 movable along an axis 6 or a hollow cylindrical fixed contact piece 8 is guided into the interior of the housing I. are.
- the power connection 4 is connected to the movable contact piece 7 via a sliding contact (not shown), while the power connection 5 is directly connected to the fixed contact piece 8.
- Both contact pieces 7, 8 are designed to be erosion-resistant and make contact with one another in the switch-on position inside a hollow insulating body 9 (left part of FIG. 1).
- the movable contact piece 7 When switching off, the movable contact piece 7 is moved out of the fixed contact piece 8 located in the interior of the insulating material body 9 and a switching arc 10 burning inside the insulating material body 9 and thereby increasing the pressure of the insulating gas is drawn between the fixed 8 and moving contact piece 7 (right part of FIG . 1).
- the fixed contact piece 8 is constructed from two parts which are designed as half-shells 11 and 12.
- the two half-shells 11 and 12 are each supported on diametrically opposite sides on a compression spring 13 and 14, which in turn are supported in a cylindrical part of the insulating body 9 acting as a cage 15.
- the two half-shells 11 and 12 are spaced apart from one another by a parting plane 16 running along the axis 6.
- the half-shells 11, 12 are at a pressure predetermined by the compression springs 13, 14 with their material recesses 21, 22 delimiting parts on the power supply 5 and with the contact points 17, 18, 19, 20 supported on the movable contact piece 7.
- compression springs 13, 14 are designed as leaf springs, as described in the previous exemplary embodiment, one ends of which in the area of the power connection 5 in points 23 and the other ends in the area of the contact points 17, 18, 19, 20 in points 24 on the outer sides of the half-shells 11 , 12 rest, differently acting contact forces can be achieved in a simple manner by forming support points 25 of the compression springs 13, 14 on the cage 15 at different distances from the support points 23 and 24, respectively.
- the two contact points 17, 19 and 18, 20 are preferably symmetrical and each rotated by an angle a of 30 to 70 ° with respect to the parting plane 16 about the axis 6 on each of the two half-shells 11 and 12, respectively. If the angle ⁇ is selected to be comparatively small, for example approximately 40 °, then the comparatively large components acting parallel to the parting plane 16 cancel out the repulsive current forces caused by the current transfer from the half-shells 11 and 12 to the movable contact piece 7 and become vertical component of the repulsive current forces acting at the parting plane 16 can be comparatively small. For a given position of the half-shells 11, 12, with a comparatively low spring force of the compression springs 13 and 14, there will always be a safe two-line contact regardless of the strength of the current to be conducted or switched.
- the current transfer from the power connection 5 to the half-shells 11 and 12 can take place in a corresponding manner through contact points 26, 27, 28, 29.
- These contact points are constructed and arranged corresponding to the contact points 17, 18, 19, 20 with regard to the power connection 5.
- these contact points also reduce the repulsive current forces that occur at the transition from the power connection 5 to the half-shells 11, 12, as a result of which the required spring forces of the compression springs 13, 14 are kept comparatively low even in the region of the end of the half-shells 11, 12 that has the current transition 5 can.
