    The gas-blast circuit-breaker has a moving (1) and a fixed switchpiece (2), each having at least one erosion contact (6, 7), and, mounted on the moving switchpiece (1), a pressure chamber (10) which stores extinguishing gas which is compressed by the arc during the switching-off process, and whose volume is independent of the switch movement, and an insulating nozzle (8) which is arranged coaxially with respect to the two switchpieces (1, 2). …<??>In this circuit breaker, it is intended significantly to increase the separating speed of the erosion contacts (6, 7) with respect to the drive speed without noticeably increasing its drive energy and without modifying its extinguishing geometry. …<??>This is achieved by the erosion contact (7) of the fixed switchpiece (2) being guided in the axial direction in a moving manner in a sliding contact (14) and being part of a converter element arranged downstream of the nozzle constriction (9) of the insulating nozzle (8) and operated by the moving switchpiece (7). During the switching-off process, this converter element transmits the movement of the moving switchpiece (1) in the opposite sense onto the erosion contact (7) of the fixed switchpiece (2). …<IMAGE>…

    专利说明:

    The invention relates to the field of electrical engineering, namely to high-voltage pneumatic switches.
    The purpose of the invention is to increase the rate of contact divergence without significantly increasing the drive energy.
    The drawing shows the contact system switch, cross section.
    The contact system contains a movable 1 and a fixed 2 contact components, each of which is connected to the current leads and has one contact. 3 and 4 of the rated current, and one arcing contact 5 and 6 each. The isolation nozzle 7 with taper 8 is located coaxially to both contact elements 1 and 2 and is fixed to the movable contact element 1. In the switching position through the taper 8 of the nozzle 7 missing arcing contact 6 fixed contact element. The constriction 8 of the nozzle 7 communicates, when it is turned off, the compression chamber 9 with the exhaust chamber 10 along the annular channel 11. made between the arcing contact 5 and the inner wall 12 of the nozzle 7 with the constriction 8.
    The contact element 2 contains a sliding contact 13, coaxially covered by the contact 4 of the rated current and connected to it by conductive bridges 14, in which an arcing contact 6 made in the form of a pin is installed with the ability to move in the axial direction. The current is transferred from the sliding contact 13 to the arcing contact 6 through the contact plates 15, and the movement of the arcing contact 6 is carried out on the support rings 16 and 17 of polytetrafluoroethylene.
    At the other-resistive contact 6 of the fixed contact element 2, a blocking element 18 and an annular ball &amp; ba 19 are secured. On which the spring 20 is supported by the lower end. The upper end of the latter rests on the sliding contact 13. A recess 21 is provided in the insulating nozzle 7, located downstream of the constriction 8, in which a spring-loaded latch 22 arranged in a rotatable manner is installed through a position

    current for the narrowing 8 hole 23. Interacting with the latch 22, the stop 24 is fixed on the surface of the internal cavity of the stationary contact element, namely on the surface of the contact 4 of the rated current.
    The switch works as follows.
    When turned off, a non-displayed drive moves the movable contact element 1 up along the axis. After a predetermined stroke, both contacts 3 and 4 of the rated current are opened and the switched off current is switched into the current circuit formed by the arcing contacts 5 and 6. At this time, the arresting contact 6 held by the latch 22 follows the contact element 1 at the same speed and when loaded by the spring 20 for as long as the latch 22 acting as a stop does not turn clockwise after a fixed period of time because of a fixed stop 24. At the same time, the locking element 18 and the arcing contact 6 serving as a part of the clamping device are released. Under the action of the compressed spring 20, the arcing contact b reverses the direction of movement (the right part of the drawing) and the arc extinguishing contact 5 and 6 now begin to move in opposite directions. Due to the relatively small inertial mass of the arcing contact 6 and the appropriately selected penetration depth of the arcing contact 6 in the hollow arcing contact 5, a high speed arc contact b can be achieved, corresponding to approximately the drive speed, but directed in the opposite direction, even when using a relatively weak spring 20 squeeze, at the time of opening of both arcing contacts 5 and 6. At the time of opening, both arcing contacts of 5 and 6 variable driven at a doyed drive speed.
    When opened between arcing contacts 5 and 6, a switching arc is formed, which fills chamber 9 with a heated insulating gas. . At the same time, due to the high speed of opening the contacts, it is achieved that the insulating gap between both arcing contacts 5 and 6
    large enough to withstand the regenerative stress. In particular, when capacitive currents are turned on, the speed of opening the contacts is a limiting value, which can be significantly increased with the help of these means without increasing the drive energy excessively and without changing the quenching geometry of the contact system.
