Definitions
- the invention relates to a contact arrangement for compressed gas switches with a tubular contact piece and an axially associated contact piece, between which an arc is drawn when switched off under load, which is blown by a compressed gas flow, the tubular contact piece on the end face and a nozzle body inside has tubular component made of ferromagnetic material at a distance.
- the invention has for its object to develop the contact arrangement of the type mentioned so that the switching capacity is increased by increasing the breaking currents, especially under conditions of short-circuit.
- this is achieved in that the inner circumferential surface of the tubular component is conical and is adapted to the contour of the nozzle body in such a way that the conical contour of the nozzle opening, which widens from the end face of the nozzle body, is continued by that of the tubular component.
- the arc behavior on the one hand and the guidance of the quenching gas flow on the other hand are improved, so that the breaking capacity is increased.
- a particularly advantageous embodiment with regard to simple manufacture is that the tubular component is fixed in position with the contact piece by a screw connection.
- the electrically conductive connection required to guide the arc during the switch-off process is thereby advantageously ensured that the tubular component and the nozzle body are electrically conductively connected to one another by the contact piece.
- the nozzle bodies, which are generally made of graphite, and the tubular components, which are advantageously made of magnetic steel, with their different expansion coefficients, which become effective under arcing stress, do not mechanically come into direct connection.
- tubular components are of identical design.
- the figure shows a section of a contact system for a compressed gas switch designed as a blow piston switch.
- the contact system consists of two fixed contact pieces 1, 2 arranged on a common axis, which bear nozzle bodies 3, 4 made of graphite on their mutually facing end faces.
- the two contact pieces 1 and 2 are bridged by a tubular bridging switching piece 5, which surrounds a plurality of spring-loaded contact fingers 6 which are distributed over the circumference of the contact pieces 1 and 2.
- a blowing cylinder 8 is moved with the tubular bypass switching element 5, which compresses the compressed gas contained in the interior 9 by pulling it over the piston 10 which is arranged essentially in a fixed manner.
- the inner lateral surface 12 of the tubular component 11 is conical and adapted to the contour of the nozzle body 3, 4, such that the conical contour of the nozzle opening 3b, 4b of the nozzle opening 3b, 4b that widens from the end face 3a, 4a of the tubular component 11 is continued.
- the tubular component 11 is fixed in position by means of a screw connection 14 with the contact piece 1, the tubular component 11 and the nozzle body 3 and 4 being connected to one another in an electrically conductive manner by the contact piece 1 and 2 are.
- the nozzle body 3, 4 and the tubular component 11 are seated on an annular intermediate body 15 which is screwed to the contact piece 1.
- the contact arrangement is provided with two tubular components 12 of identical design.
