Definitions
- the invention is in the field of electrical circuit breakers and can be used in the structural design of a switching chamber, as is used in metal-encapsulated gas pressure switches.
- the actual contact system in a switching chamber, the housing of which essentially consists of an insulating tube surrounding the contact system with field control elements axially adjacent to the insulating tube and a current supply element assigned to each field control element consists.
- the switching chamber is arranged axially in a tubular metal encapsulation and provided with a drive device arranged coaxially thereto for the axially displaceable contact element of the contact system.
- the contact elements of the contact system are fixed or mounted on the power supply elements.
- the insulating tube of the switching chamber is generally made of a resin-impregnated fabric web and centered at its ends in the field control elements and radially glued there to these field control elements.
- the manufacturing measures required for this arrangement and design of the insulating tube are relatively complex (DE 32 40 774, DE 39 04 147).
- the invention has for its object to design the housing of the switching chamber so that it is easy to manufacture and easy to align with the adjacent parts of the circuit breaker, in particular with respect to the power supply elements.
- the insulating tube consists of cast resin and is provided at one end with an inner flange and at its other end with an outer flange and that annular metallic pressure elements are provided for fixing the insulating tube to the power supply elements which the pressure element assigned to the outer flange also serves as a field control element.
- the insulating tube can be axially screwed to the current supply elements by means of the pressure rings, the pressure rings pressing the respective flange of the insulating tube against a corresponding surface of the adjacent field control element or the current supply element.
- No cast-in metal bushings are required in the flanges of the cast resin tube, which could result in warping of the cast resin tube when cooling in the mold.
- this configuration avoids dielectric problems that could occur when dirt parts are deposited at the connection points of different pipe parts.
- the pressure rings used in the invention can - if necessary - be given such an outer contour that they also perform a field-controlling function.
- FIG. 1 shows the metal housing 1 of a single-pole compressed gas circuit breaker, in its tubular housing part a switching chamber 2 is arranged axially.
- An essential part of this switching chamber is formed by the insulating tube 3, which is made of cast resin and, according to the cutouts in FIGS. 2 and 3, is provided with an inner flange 4 at its left end and with an outer flange 5 at its right end.
- the insulating tube 3 is connected to the power supply element 6.
- a pressure ring 7 is used, which is placed against the inner flange 4 from the inside and screwed to the power supply element 6.
- the insulating tube 3 is connected to the current supply element 8, which in its section 9 adjoining the insulating tube has a field-controlling function.
- a flange 10 is provided, on which the outer flange 5 of the insulating tube 3 abuts, the insulating tube being fastened to the section 9 by means of a screw connection by means of the pressure ring 11.
- the pressure ring 11 has such an outer contour that it also exerts a field-controlling effect.
- the power supply element 8 is fixed to an inner flange of the metal housing 1 via an insulating tube 12 and thus carries the entire switching chamber 2.
