Definitions
- the invention is in the field of electrical switches and is to be used when operating vacuum interrupters that have two switch contact pieces movable relative to each other and where the breaking capacity is influenced improved the timing of the opening of the switching path shall be.
- a drive linkage is provided for moving the movable switching contact piece, which is electrically guided outwards via a power supply bolt, which acts on the movable switching contact piece when switched on via a contact pressure spring and that when switched off - after a certain distance has been covered Acceleration path - the movable switch contact takes suddenly.
- a power supply bolt which acts on the movable switching contact piece when switched on via a contact pressure spring and that when switched off - after a certain distance has been covered Acceleration path - the movable switch contact takes suddenly.
- a contact piece separation speed of 2 m / s is reached after 0.8 ms.
- the separation speed of the movable switching contact piece is essentially constant over the entire contact stroke, apart from the phase of the high initial acceleration and the strong braking when the full contact stroke is reached (DE 38 15 805 C2).
- a high-voltage vacuum switch is also known, in which the contact stroke is divided into three sections (the switching stroke, a first step of the insulating stroke and a second step of the insulating stroke) by means of a special design of the vacuum interrupter.
- the special structural design consists of the assignment of a potential ring to each contact piece and an axially displaceable arrangement of the housing of the vacuum interrupter relative to the fixed switching contact piece.
- a vacuum interrupter for an operating voltage of is designed at least 12 kV and two in one housing relatively movable, via power supply bolts has switch contacts routed electrically to the outside (DE 38 15 805 C2), the invention is based on the object through a targeted intervention in the timing of the Switch-off characteristics continue to increase the breaking capacity improve.
- the invention provides that the contact pieces in a first, the power cut serving phase of the separation movement at a first speed to a contact pitch of about 1/4 to 1/2 one given final distance and that the contact pieces in a second one, used for voltage insulation Phase of the separation movement at a second speed be brought to the specified final distance, the first speed greater than the second speed is.
- the first speed is expediently at least three times the second speed.
- the switch-off process by sequential succession of a first section with a fast switching speed and a second Section with a slow switching speed temporally in the functions "current extinguishing / extinguishing stroke” and "voltage isolating / insulating stroke" divided, the extinguishing stroke so to be selected is that the switching arc at the next zero current crossing safe within a time of 2 to 15 ms extinguished. Then the switching path on the dielectric necessary distance between the switch contact pieces opened.
- the dielectric strengthening the switching path thus runs after the zero current crossing much faster than the increase in recurring Tension.
- the dielectric strength is at The extinguishing stroke is always greater than that of the respective voltage level associated transient return voltage.
- the adjustment of the dielectric field strength of the switching path to the network conditions, especially the lightning impulse withstand voltage, is then carried out by further increasing the contact stroke with greatly reduced speed.
- vacuum interrupters those with radial field contacts or with magnetic field contacts provided and for an operating voltage of 12 up to 36 kV are dimensioned as Proven appropriately, according to which the first speed about 0.5 to 2 m / s and the second speed about 0.1 to 0.3 m / s.
- the extinguishing stroke is about 3 to 5 mm and the total contact stroke is about 8 to 20 mm.
- the extinguishing stroke is approximately 20 mm and the total contact stroke about 40 to 60 mm.
- the two speeds when opening the switching path can be achieved in different ways. For example can attenuators in previously common drive mechanisms be inserted. An embodiment of this shows Figure 2. But you can also use the appropriate drive Design cams so that the movable Switch contact positively controlled by means of a cam becomes. Such a control is in principle the figures 1 and 2 of DE 27 02 962 A1. - A particularly useful one Possibility of generating the two speeds is seen in a further embodiment of the invention in that the two switch contacts move in opposite directions be, the one switch contact piece only during the first phase of the separation movement at the first speed and the other switching contact piece only during the second or also during the first and the second phase of the separation movement is moved at the second speed.
- FIG. 1 shows a diagram, in which the switching stroke is shown over time.
- the switching path is opened in two sections S1, S2, represented as straight lines with different slopes are.
- the straight line S1 shows that the extinguishing stroke Lh is reached after a time t1, for example at a Separation speed of the contact pieces of 1 m / s and one Extinguishing stroke of 5 mm is 5 ms.
- the straight line S2 shows that the final stroke Eh reaches t1 plus t2 after a time which, for example, at a separation speed of 0.2 m / s and a final stroke of 20 mm is approx. 100 ms.
- FIG. 2 is a drive rod 1, which in no closer shown way to the movable contact piece of a vacuum interrupter is coupled, a switch-off spring 2 assigned, which - supported on a circuit board 3 - via a plate 4 acts on the drive rod 1.
- the plate 4 is at the same time Part of a damping arrangement, to which a pot 5 and include an attenuator 6 disposed in the pot.
- the plate 3 initially moves unimpeded into the pot 4 to a depth D1, the corresponds to the extinguishing stroke of the associated vacuum interrupter.
- There the plate 4 meets the compressible one Attenuator 6, which increases the speed at which the Plunge plate 4 further into pot 5 until it is reached position D2, which corresponds to the final stroke of the vacuum interrupter, is reduced accordingly.

Abstract
Description
Es ist weiterhin ein Hochspannungs-Vakuum-Schalter bekannt, bei dem der Kontakthub mittels einer speziellen konstruktiven Gestaltung der Vakuumschaltröhre in drei als "Funktionsstufen" bezeichnete Abschnitte (den Schalthub, eine erste Stufe des Isolierhubes und eine zweite Stufe des Isolierhubes) unterteilt ist. Die spezielle konstruktive Gestaltung besteht in der Zuordnung von jeweils einem Potentialring zu jedem Kontaktstück und einer axial verschiebbaren Anordnung des Gehäuses der Vakuumschaltröhre gegenüber dem feststehenden Schaltkontaktstück. Diese Maßnahmen bewirken, dass sich die beiden Schaltkontaktstücke in der Aus-Stellung des beweglichen Schaltkontaktes im Feldschatten des jeweiligen Potentialringes befinden, wodurch das Isoliervermögen der Vakuumschaltröhre bei gegebenen Kontaktabstand verbessert wird (DE 195 19 078 A1).
