Definitions
- the present invention relates to a contact piece for an electrical switching device, in particular for a contactor, according to the preamble of claim 1 and an electrical switching device with at least one such contact piece.
- Contact pieces for electrical switching devices are known in which the current carrying part is C-shaped, the contact pad being arranged on the top of the upper leg (CH-PSen 506 871 and 559420).
- An arc runner made of ferromagnetic material connects to the contact pad.
- An electrical switching device provided with at least one contact piece according to the invention is characterized by the features of the characterizing part of claim 7.
- the contact piece can be replaced by detaching it from the power supply rail in a relatively simple manner without having to disconnect the power supply rail from the conductor connected to it.
- the arc guide piece 6 consists of ferromagnetic material, preferably of a magnetically soft material.
- One leg 6a of the L-shaped arc guide piece 6 extends in the opposite direction to the flow direction A (FIG. 2) of the current in the current guide piece 2 away from the contact pad 5 and lies on the current guide piece 2.
- This leg 6a and the current guiding piece 2 there is an intermediate layer 7 arranged from an electrically insulating material.
- This intermediate layer 7 can be a mica plate, for example.
- the other leg 6b protrudes from the leg 6a at an angle of approximately 90 ° .
- connection point 8 the current guide piece 2 and the arc guide piece 6 are connected to one another by means of two rivets 9.
- This connection point 8 lies, in the direction of current flow A already mentioned, in front of the contact pad 5.
- the leg 6a is provided at its end with two tongues 10 and 11 running parallel to one another, between which there is a recess 12. With these two tongues 10 and 11, the leg 6a engages around the contact pad 5 laterally.
- the contact piece 1 shown in Fig. 3 differs from that according to Figs. 1 and 2 only in the different shape of the contact pad 5.
- FIG. 4 shows, in section, part of one of the two halves of a contactor 13 which are arranged in mirror image to one another and which is equipped with two contact pieces 1 according to FIGS. 1 and 2 or 3. Because of the mirror-image arrangement of the two housing halves, the following description of FIG. 4 is also valid for the half of the contactor 13 that is not shown.
- the contact arrangement of the contactor 13 is accommodated in a housing 14 made of an electrically insulating material.
- a wall 14a extends through one wall 14a of the housing
- the power supply rail 15 is provided with a connection 17 for an electrical conductor.
- the current-carrying part 2 of the contact piece 1 lies on this current-supply rail 15 and is detachably connected to the current-supply rail 15 by means of a screw 18 which extends through the recess 3 in the current-carrying part 2.
- the contact arrangement also has a movable contact bridge 19, to which two contact plates 20 are attached, which are connected to one another via a connecting part 21 made of an electrically conductive material, for example copper.
- the connecting part 21 is fastened to a carrier 22.
- the contact arrangement is surrounded in a manner known per se by an arc quenching chamber 23 which is provided with a number of quenching plates 24 arranged at a mutual distance and parallel to one another. Vent openings 25 are also provided in the housing.
- the leg 6b of the arc guide piece 6 extends approximately parallel to these quenching plates 24 and is arranged between them and the housing wall 14a net. This leg 6b thus closes the arcing chamber 23.
- the design of the contactor 13 described allows the contact piece 1 to be easily replaced. When the housing 14 is open, it can be removed by loosening the screw 18 and replaced by a new contact piece. It is not necessary to disconnect the power supply rail 15 and the conductor connected to it.
- the electrical separation of the leg 6a from the current-carrying piece 2 by means of the insulation intermediate layer 7 has the effect that, when the arc foot point is located behind the connection point 8 as seen from the contact pad 5, the current flow direction in the leg 6a is opposite to the flow direction A of the current in the current-carrying piece 2, as a result of which rapid migration of the arc to the quenching plates 24 is ensured.
- the leg 6a of the arc guide piece 6 and the current guide piece 2 can also be electrically insulated from one another in a manner other than that shown.
- the intermediate layer 7 instead of the intermediate layer 7, it is possible to have an electrically insulating coating, e.g. to apply an oxide layer.
