Definitions
- Switching chamber housing for a circuit breaker and housing modules for producing such a switching chamber housing
- the invention relates to a switching chamber housing for a circuit breaker with a rotary double breaker, the switch chamber housing being composed of two housing modules and the rotary double breaker two fixed switching pieces, each of which is connected to corresponding connecting terminals via rail-shaped conductors, and a two-armed switching piece which can be rotated about an axis , which in its closed position connects the two fixed contact pieces to one another, the fixed contact pieces being designed in such a way that, in the event of an overload, forces arise between them and the current-carrying rotating contact piece due to the magnetic fields, which move the rotating contact piece into an open position pivoted, and wherein in order to extinguish the arc formed between the switching pieces in the area of the fixed switching pieces, a quenching chamber is arranged.
- the invention further relates to housing modules for producing such a switch chamber housing.
- Switching chamber housings for circuit breakers that can be assembled from two separate housing modules per phase of the network are known, for example, from EP-Bl-542 636. They are easy and quick to assemble. Besides, only needs to each consist of a relatively small switching chamber housing made of an arc-proof material.
- the higher-level housing on the other hand, in which the number of switching chamber housings corresponding to the number of phases is located, can consist of a cheaper material.
- the known housing modules essentially form two shell-shaped housing parts which are symmetrical with respect to the central plane in the longitudinal direction of the switch chamber housing. To assemble the switching chamber, the switching pieces, baffle plates, etc.
- a disadvantage of the known switching chamber housings is, inter alia, that the quenching chambers of such switching chamber housings only arise through the connection of the two housing modules. Therefore, a complete function check of the quenching chambers is generally not possible before the switching chambers are assembled. To eliminate sources of error, especially in the quenching chambers, it is therefore often necessary to dismantle the entire switching chamber when using known switching chamber housings.
- the invention is based on the object of specifying a switchgear chamber housing which can be assembled from two housing modules and which has the advantages of known housings of this type, is simple and inexpensive and in which the erase chambers each have a reproducible erase behavior after assembly of the switch chamber. Furthermore, housing modules that can be used to produce such switching chamber housings are to be disclosed.
- the interrupter housing consists of two essentially
- L-shaped housing modules is to be assembled, whose the first leg corresponding first housing part is designed as an erasing chamber.
- the two interconnected housing modules are preferably constructed identically, so that they do not have to be manufactured and stored separately.
- the object is achieved with respect to the housing modules in that the first housing part forming the first leg of the L-shaped housing module is designed as a quenching chamber (19), that within the quenching chamber both one of the fixed switching pieces and the arm of the rotatable element assigned to the respective fixed switching piece Switch piece to be arranged and that the second leg forming the second housing part of the housing module is designed as a bearing block for a shaft actuating the rotatable switching piece.
- the switching chamber housings according to the invention have the great advantage that in each housing module the corresponding quenching chamber with quenching plates, etc. can be completely pre-assembled before the assembly of the switching chamber housing and its function can be checked if necessary.
- the two fixed switching pieces can each be permanently preassembled in one housing module or both switching pieces together only in one housing module.
- the second housing module with the corresponding extinguishing chamber then only needs to be attached to the first housing module to assemble the switchgear chamber housing to be attached with an otherwise fully assembled rotary double breaker.
- the housing modules are simultaneously designed as a support body for the rail-shaped conductors which are arranged between the respective fixed contact piece and the respective connection terminal.
- recesses are provided on one or both outer sides of the first housing part, into which corresponding loop-shaped, rail-shaped conductors, in particular with connecting webs at the ends, can be inserted.
- a recess is also provided on the outside of the second housing part in the area on the edge facing away from the first housing part. A partial section of the rail-shaped conductor arranged between the respective fixed contact piece and the corresponding connecting terminal can be inserted in this recess.
- the housing module expediently consists of a plastic pressed part.
- Fig.l the side view of a first embodiment of a switching chamber housing according to the invention with switching elements shown in dashed lines;
- FIGS 3 shows a perspective view of a second exemplary embodiment of a switching chamber housing according to the invention before the two housing modules are assembled, both the fixed switching pieces and the rotatable switching piece being completely preassembled on a housing module.
- Fig.l 1 denotes a switching chamber housing, which is composed of two identical L-shaped housing modules 2 and 3, the inner edge surfaces 4, 5 of which face each other.
- the housing modules consist, for example, of a suitable plastic pressed part.
- a rotary double breaker known per se, which essentially consists of two fixed switching pieces 6, 7 and a switching piece 9 bridging the fixed switching pieces and rotatable about an axis 8.
- the fixed switching pieces 6, 7 are each connected to corresponding connecting terminals 12, 13 via rail-shaped conductors 10, 11.
- the rotatable switching piece 9 can be pivoted in the direction of arrow 15 by means of a shaft 14.
- the shaft 14 is guided through the side wall 16 of the switching chamber housing 1.
- the first housing part 17 or 18 corresponding to the vertically shown first leg of the respective L-shaped housing module 2 or 3 contains a quenching chamber 19 (FIG.
- the second housing part 22 or 23 of the respective housing module 2 or 3 forming the horizontally represented, second leg is designed as a bearing trestle for the shaft 14 of the rotatable switching element 9, the side walls 24, 26 and 25 of the second housing part 22 and 23 forming the bearing block having semicircular openings 27, 29 and 28 which enclose the shaft 14.
- the assembly of the entire switching chamber 1 is very simple: the extinguishing plates (not shown) and the fixed switching pieces 6, 7 with the rail-shaped conductors 10, 11 are inserted and mounted in the two finished housing modules 2, 3 and, if necessary, the function of the extinguishing chambers 19 tested. Furthermore, the rotatable contact piece 9 is optionally inserted in one of the second housing parts 22, 23 and optionally fastened. Then the two housing modules 2, 3 are connected to one another with the preassembled switch contact parts, e.g. screwed, riveted, locked or welded.
- the invention is of course not limited to the embodiment described above. So the two housing modules do not have to have an exactly L-shaped shape. Rather, the outer contour of the housing modules in particular will generally deviate from the L-shape, so that the interrupter housing can be inserted into corresponding superordinate housings.
- the housing does not have to be designed such that the rail-shaped conductors must also be accommodated in the arcing chamber.
- the respective housing module as a support body for the conductors which can be arranged on the outside of the respective housing module.
- FIG. 3 A corresponding exemplary embodiment is shown in FIG. 3:
- the switching chamber housing, designated 30, is in turn composed of two identical, essentially L-shaped formed housing modules 31, 32 together.
- Each housing module 31 or 32 in turn has a first housing part 33 or 34 and a second housing part 35 or 36.
- the housing modules 31, 32 are designed such that both the two fixed switching pieces 37 and the rotatable switching piece 38 can optionally be pre-assembled on one of the two housing modules 31, 32 to be connected to one another.
- the respective other housing module then only contains a quenching chamber, possibly with quenching plates.
- the rail-shaped conductors 41, 42 connecting the fixed switch pieces 37 and connecting terminals 39, 40 are each formed as a U-shaped or L-shaped double loop in the exemplary embodiment shown and in recesses 45, 46 and 43, 44 on the edges on the outer sides 47, 48 or 49, 50 of the first or second housing part 33, 34 or 35, 36 to be arranged.
- the respective loop ends are connected to one another via conductive connecting webs 51, 52.
