Definitions
- the invention relates to a circuit breaker with one arranged within its housing
- Arc chamber which receives the stack of quenching sheets, which merges behind a slotted door and into a blow-out chamber which is open to the outside and which, in turn, has integrally formed walls on two half-shells of the housing transversely to the main flow direction.
- Miniature circuit breakers with such an arc chamber are known (DE-PS 1 238 538, DE-OS 29 49 012).
- the partition wall which is arranged directly behind the extinguishing plates and which lies closely against their end edges is provided with slots, each in the gap between two
- Arc gases often have such a large one
- Switching gas discharge channel has been proposed. This is subdivided into an expansion space adjoining the quenching plate package and downstream flow channels, a further expansion space and an outlet channel. In this arrangement there is a behind the quenching plates considerable risk of reignition, if not on
- Cover part forming outlet channels made of extinguishing gas-dispensing material is provided, which complements the circuit breaker and must be attached to the housing from the outside in a separate operation. Such an extra part means a not inconsiderable additional effort for a switchgear manufactured in large series.
- the invention is based, with one
- Arc gases have to flow around several walls that are staggered in a labyrinthine manner on their way from the stack of quenching plates, due to the longer length
- Arc gases are directed into different directions by means of blow-out nozzles, so that a concentrated jet does not occur in one direction, but rather there is a strong scattering of the arc gases. Because the specially designed blow-out chamber when pressing the housing parts can be produced in a practically cost-neutral manner, the solution according to the invention results in a strong reduction of the escaping arcing gases with little effort - and this without significant impairment of
- Fig. 1 shows a circuit breaker in a simplified
- FIG. 2 is a partial section along the line II - II (Fig. 1),
- Fig. 3 is a partial section along the line III - III
- Fig. 4 schematically shows a special embodiment of the
- Fig. 5 is a view of the side wall from the direction of
- Fig. 6 shows a section along the line VI - VI (Fig. 5).
- Narrow construction has a made of insulating material
- Housing (1) which consists of two half shells (1a, 1b)
- an arc chamber (2) is arranged in the base area of the housing, which is largely filled by a stack of quenching plates (3).
- the individual quenching plates (3a) are included their left-hand end edges on a partition (2a) which is formed on the housing and separates the arc chamber (2) from a blow-out chamber (4).
- a partition (2a) which is formed on the housing and separates the arc chamber (2) from a blow-out chamber (4).
- interlocking walls (4a) - as is particularly indicated in Fig. 2 - before they reach the outside through a blow-out opening (4b).
- the walls are molded directly onto the two half-shells (1a, 1b) of the housing,
- thermoset which preferably consists of a thermoset.
- thermoset which preferably consists of a thermoset.
- the walls (4a) rise and at least from the bottom of the half-shells to at least over the middle
- Pin (4a ') chosen so that despite high arc cooling and a low emission of conductive
- FIGS. 1 to 3 can still be optimized with the essential features of the blow-out chambers according to the invention, as shown in the exemplary embodiment according to FIGS. 4 to 6.
- blow-out chamber (4 ') shown in FIG. 4 only as a section of the circuit breaker has behind the
- Walls (4a) instead of a blow-out opening, a plurality of blow-out nozzles (4c). These are arranged on both sides of the parting line between the two half-shells (1a, 1b) and offset in such a meandering manner that the actual openings in the outer side wall (1d) each in
- Blow-out nozzles are not formed in the side wall (1d) at right angles, but rather at an angle of approximately 45 ° to the direction of the walls (4a).
- the exhaust nozzles (4c) in the two half-shells are mutually offset by approximately 90 °, as shown in FIGS. 4 and 6
- blow-out chamber can be divided into two half-spaces of equal size by a partially inclined rib (4d). 1, the rib (4d) is approximately in the middle of the
- Partition (2a) attached and runs at the same oblique angle as the individual slots (2b). This ensures good guidance of the arc gases flowing out at an angle from the arc chamber into the blow-out chamber and prevents the tendency to re-ignition directly behind the extinguishing plates.
- the rib (4d) is just like that Walls (4a) and the other elements of the blow-out chamber each form part of the two half-shells of the housing and thus represent a cost-neutral solution.
