Definitions
- Switching contact arrangements of the type mentioned, as by the DE-B 1 118 317 have become known, are distinguished Arrangements with only one or two contact points by a higher switching capacity, increased service life and lower Heating at continuous activation off. They are therefore in Low-voltage circuit breakers for particularly high loads used for a rated current of several thousand amps and a breaking capacity up to about 100 000 A can be designed.
- An elimination runs in the way that the final separation of the movable contact group from the fixed contact group only on the break contacts takes place, which according to their function also as Abbrennessore, arcing contacts or pre-contacts be designated.
- the main contacts are opened before, so that they are not or only slightly stressed by switching arcs become. Therefore, the main contacts keep one large number of circuits a good condition and current carrying capacity remains in low heat in continuous operation received over a long period of time.
- the invention is in this context the task underlying, a switching contact arrangement with triple contact to create the type mentioned, for the production requires a much lower effort and yourself at the same time characterized by an increased service life.
- FIG. 1 is a schematic illustration of a low-voltage circuit breaker with a switch contact arrangement.
- FIG. 2 shows a switching contact arrangement according to the invention shown in the on state.
- Low-voltage circuit breaker 1 has a housing 2 and from this back outstanding busbars 3 and 4 on.
- a designated as a whole with 5 switching contact arrangement is in electrical connection with the busbars 3 and 4 and allows closing and opening a circuit for consumers (not shown).
- Above the switch contact arrangement 5 is located in the housing 2 an arc extinguishing chamber 6, in a known manner across a Contains switching arc arranged quenching plates.
- the switch contact arrangement 5 comprises a fixed contact group 7, which is in communication with the upper busbar 3, as well as a movable contact group 10 by means of flexible conductor 11 is connected to the lower bus bar.
- To the movable Contact Group 10 includes a contact carrier 12, the pivotally mounted in the housing 2 of the circuit breaker 1 and by a drive device 13 for switching on and off is operable.
- a pivotally mounted on the contact carrier 12 Contact lever 14 is by a contact force spring 15 in the Direction of the fixed contact group 7 biased.
- a Switching shaft 16 is used for distribution of the drive device 13 provided driving force on several in the housing 2 mutually parallel switching contact arrangements 5, each of which by a lever mechanism 17 with the Switch shaft 16 is connected.
- the fixed contact group 7 at the end face its busbar 3 is provided with a contact pad, which forms a fixed main contact 20.
- the above the main contact 20 located part of the end face of the Busbar 3 forms a fixed intermediate contact 21st
- the fixed main contact 20 acts a movable Main contact 22 together, by a contact lever on the 14th attached contact pad is formed.
- a protrusion of the Contact lever 14 serves as a movable intermediate contact 23rd
- the movable contact group 10 comprises, as already mentioned, a Contact carrier 12 and a contact lever 14.
- the contact carrier 12 is movable about a stationary pivot bearing 27, while the contact lever 14 to a on the contact carrier 12th arranged pivot bearing 30 is movable.
- Two parallel Contact force springs 15 are supported on the contact carrier 12 and clamp the contact lever 14 against the fixed contact group 7 before.
- Above the intermediate contact 23 is the contact lever 14 formed as an arcing horn 31, wherein a Part of the arc horn 31 as a movable break contact 32 serves, as will be explained.
- the transfer of the switching contact arrangement 5 in the position OFF is in a known manner by a corresponding rotation the switching shaft 16 initiated.
- the contact carrier 12 leads now a clockwise turn, while the contact lever 14 under the influence of the contact force springs 15 first still engaged with the fixed contact group 7 remains in the counterclockwise direction be located on the contact carrier 12 pivot bearing 30th swings.
- As the first characteristic intermediate position occurs while the position according to the figure 3. This position is characterized by the fact that both the main contacts 20 and 22 and the intermediate contacts 21 and 23 touch. As a result, the commutation of the over the switch contact arrangement 5 flowing current prepared for the intermediate contacts.
- FIG. 4 shows as a further characteristic intermediate position the state that both the main contacts 20 and 22 as also the intermediate contacts 21 and 23 are separated from each other and the current to be interrupted only via the break contacts 26 and 32 flows.
- a switching arc ignited at the tear-off contacts 26 and 32 In the subsequent separation of the Contact lever 14 of the fixed contact group 7 is a switching arc ignited at the tear-off contacts 26 and 32. Since the break contacts, as explained above, components the fixed and the movable arcing horn 25 and 31, therefore, there are particularly favorable conditions for the continuation of the switching arc and its Transfer into the arc quenching chamber 6 ( Figure 1). These Property allows surprisingly short switching times.
- the fixed arc horn 25 can also formed integrally with the fixed intermediate contact 21 be (EP 0 325 767 B1) or additionally in one piece with the Busbar be formed (EP 0 859 387 A2). on the other hand can the movable arcing horn in a known manner as a separate Part formed and attached to the contact lever (EP 0 325 767 B1).
- other versions of Stops limiting the pivot angle of the contact lever 14 as considered suitable for the purposes of the invention.
