Definitions

  • Switching pole for low-voltage switchgear with linearly movable contact carrier
  • the invention relates to a switching pole for low-voltage switching devices with a linearly movable contact carrier for a movable switching contact, which interacts with a fixed switching contact attached to a connecting rail, and with a drive device for the movable contact carrier.
  • Switchgear with a switching pole of this type are e.g. B. described in DE 12 50 532 B or DE 18 14 550 Cl. This is Sagittarius.
  • the object of the invention is to develop a new, high-performance design for another type of low-voltage switchgear, namely circuit breakers. Certain, apparently advantageous features of contactors cannot be easily used in circuit breakers, as will be explained in more detail below.
  • Low-voltage circuit breakers consist of several modules that are adapted to the different subtasks and that are connected to one another during the manufacture of the circuit breakers.
  • the largest assemblies, or units, form the switching poles, that is, the contact systems consisting of fixed and movable switching contacts with their support insulation and the drive device common for several such contact systems.
  • Transmitted motion sequences provided to the contact systems via a stationary shift shaft.
  • this rotatably mounted control shaft which can be pivoted through a certain angle by means of a spring accumulator or other switch drive, is also part of the latter
  • switching shaft outgoing further levers, via which the individual switching poles or movably arranged on contact sluggish contacts are actuated.
  • Such contact carriers have hitherto generally been pivotably mounted in low-voltage circuit breakers. This results in a relatively high design, with effects on the overall height of the switch housing and a relatively complicated structure.
  • a movable contact carrier of this type is known from DE 35 39 786 AI.
  • the bearing arms are part of a bearing bracket, which is adapted to a holding body for the contact lever. It is a construction consisting of several metal parts.
  • Movable contact carriers are also known which are composed of a combination of plastic molded parts and metal parts.
  • DE-296 15 566 U describes a movable switch contact arrangement for a low-voltage circuit breaker with contact levers and a contact lever holder which receives the contact lever and is pivotably mounted by means of lateral bearing arms for switching on and off.
  • This contact lever carrier has a central part that a base body and at least one attachable to it
  • Both of the movable contact carriers mentioned are composed in a conventional manner from several individual components. Added to this is the fact that voltage carry-over can occur with metal support arms.
  • EP-PS 0325 767 B1 particularly recognizable from FIGS. 3 to 5. Although a switch-on process is shown here, it is clear that the sequence when switching off is in reverse order. It can also be seen here that the main contact is prevented from burning up by opening the contact later.
  • the object of the invention is therefore one
  • the switching pole consists of a box-shaped housing, through the housing rear wall of which the connecting rail provided with the fixed switching contacts is inserted and through the housing rear wall of which a further connecting rail is passed, with which a flexible conductor arranged on the contact carrier, pivot contact mounted on a shaft is connected as a movable switching contact, and that cooperating guide elements on opposite walls of the switching pole and on the movable contact carrier tel for linearly movable guidance of the contact carrier in
  • the invention surprisingly combines the advantages of linearly movable contact carriers and pivotably arranged contact levers. It is also achieved that the switching pole is suitable for any type of actuation, in particular also linearly acting drives.
  • a switching pole for a contactor with a box-shaped housing has already become known, from this projecting connecting rails and a swivel contact.
  • the swivel contact is however stored in the housing of the switching pole, i. H. there is no separate contact carrier.
  • the linear guidance of the contact carrier in the switching pole according to the invention can be designed such that the housing side walls of the switching pole have guide grooves in the direction of movement of the contact carrier and suitable extensions are provided on the sides of the contact carrier for sliding in these guide grooves.
  • the contact carrier can advantageously be designed as a molded plastic part.
  • the extensions on the sides of the contact carrier can also be designed as continuous ribs running in the direction of movement of the contact carrier.
  • the movable switching contacts arranged on the contact carrier mounted on a shaft and designed as pivot contacts known per se, are supported by means of contact force on the contact carrier and have conventional pre-contacts on, which cooperate with corresponding counter-contacts on the fixed switching contacts to reduce the erosion of the main contacts.
  • the movement of the contact carrier is brought about by a conventional switch drive via an actuating element in a known manner, so that no new technologies and an associated outlay are required for this.
  • the contact carrier can be displaced in a straight line, which is relatively easy to implement by means of a structurally simple technical design, and is of course particularly well suited for a linearly acting drive, such as a magnetic drive.
  • a linearly acting drive such as a magnetic drive.
  • the present invention proposes the combination of a swivel contact, with all of its advantages in the low-voltage circuit breaker, with a linearly movable switch drive, with its advantages. This means that the conventional, very advantageous arrangement of the connecting rails can be retained, and yet the advantages of a linearly moving system with regard to the drive and the guide can be used.
  • 1 shows a switching pole for a low-voltage circuit breaker with a linearly movable contact carrier in the switched-off state.
  • 2 shows a switching pole for a low-voltage circuit breaker with a linearly movable contact carrier in the switched-on state.
  • Fig. 3 shows a switching pole for a low-voltage circuit breaker with linearly movable contact carrier in a perspective view with the rear wall removed.
  • the switching pole 1 shows a switching pole 1 for a low-voltage circuit breaker with a linearly movable contact carrier 2 in the switched-off and in the switched-on state.
  • the switching pole 1 consists of a box-shaped housing through the rear wall 3 of which the upper connecting rails 4 are inserted, on which the fixed switching contacts 5 are arranged.
  • Flexible conductor cables 7 are connected to the lower connecting rails 6, which are likewise passed through the rear wall 3 of the housing, as a connection to the movable switching contacts 8 arranged on the movable contact carrier 2.
  • guide grooves 11, 12, 13, 14 are provided for receiving extensions 15, 16 arranged on the linearly movable contact carrier 2, by means of which the contact carrier 2 in the housing of the switching pole 2, guided by the guide grooves 11, 12, 13, 14, li- is movable near.
  • the contact carrier is a plastic
  • Molded part and carries the mounted on a shaft 17, designed as swivel contacts, movable switching contacts 8, which are supported by contact force springs 18 on the contact carrier 2 and have in a conventional manner pre-contacts 19 with counter contacts 20 on the fixed
  • the movement of the contact carrier 2 is controlled via an actuating element 21 by a switch drive 22 shown schematically effected in a conventional manner.
  • This actuating element 21 moves the contact carrier 2 in the direction of the arrow in FIG. 1 linearly to the fixed switch contact 5 until the movable switch contacts 8 come into contact with the fixed switch contacts 5 and the switch-on state according to FIG. 2 is reached.
  • the contact carrier is brought back into the switch-off position according to FIG. 1.
  • Fig. 3 shows a switching pole 2 for a low-voltage circuit breaker with linearly movable contact carrier 2 in a perspective view with the rear wall removed.
  • guide grooves 11, 12 and 13, 14 are provided, in which the contact carrier 2 is guided by means of the extensions 15, 16 for realizing a linear movement, as was described with reference to FIGS. 1 and 2.
  • movable switching contacts 8 Arranged on the contact carrier 2 are the movable switching contacts 8 which are designed as pivotable switching contacts and which are connected by means of flexible conductor cables 7 to the lower connecting rail 6 (not shown) (FIGS. 1 and 2).
  • the advantage of the solution according to the invention is that the advantages of a linear movement of the contact carrier can be combined with the advantages of the applicability of the swivel contacts which have been proven in practice with main and pre-contact.
  • the space requirement of a linearly movable contact carrier is less and its construction is much simpler.
  • the baffles of the arc quenching chamber do not have to be adapted to the path of the contact carrier and act more effectively because the distance between the contact carrier and the arc quenching chamber is constant throughout the movement. The number of parts is additionally reduced by the same guide plates. LIST OF REFERENCE NUMBERS
