Definitions
- the invention relates to an electrical protective switching device according to the preamble of claim 1.
- Switchgear with a parts carrier made of insulating material are known, in which connecting pieces, contact angles and the like can be preassembled so that a completely preassembled unit can be fastened in a switchgear housing.
- auxiliary modules such as U / A triggers, auxiliary switches, AGM
- Blocks that are provided with fastening lugs to be attached to the basic housing There are openings on the housing, which are marked with a
- the invention is therefore based on the object of providing a switching device according to the preamble of claim 1, on which auxiliary modules from another series of devices can be used, the assembly of the individual parts being intended to be simple.
- FIG. 1 is a perspective view of the switching device with an unassembled auxiliary module
- FIG. 2 is a perspective view of the parts carrier with parts pulled apart
- Fig. 3 is a perspective view of the parts carrier with assembled
- Fig. 4 is a perspective view of the parts carrier with one
- Fig. 5 is an illustration of the parts carrier from the side with assembled
- Fig. 8 is a perspective view of the parts carrier with the
- FIG. 9 shows another perspective view of the parts carrier with the
- Fig. 11 is a sectional view of the protective switching device
- 15 is a perspective view of the release unit mounted in the housing.
- FIGS. 3 and 4 show an electrical protective switching device 1 for protecting motors, also known as motor protective switches, with a rotary drive and a rotary head 11 for switching on and off and indicating the triggering in the event of overload or short circuit, and a housing 12 which is in three housing parts 13, 14 , 15 is divided.
- the middle housing part 14 has cable entry openings 16 with cable clamps 17, which are shown in FIGS. 3 and 4.
- Fig. 2 shows the parts carrier 5, on which a connector 6 can be attached.
- the connector 6 is made of copper and is L-shaped, the lower outward leg 18 being provided as a contact tap for the cable clamp 17.
- the parts carrier 5 has a fixing pin 23 which projects into a corresponding recess on the lower leg 18 of the connector 6.
- the upper leg 21 of the connecting piece 6 is provided with a connecting zone 19 to which a heating element 22 or heating conductor of a known type wrapped on a bimetal spring or bimetal 8 is electrically and mechanically connected.
- This first connection zone 19 is realized with inert gas welding or plasma welding, this first welding point 24 being shown in more detail in FIG. 5.
- the subsequent welding points 25, 26, 27 are also realized with inert gas welding.
- a second welding point 25 is present at the connection point between the heating element 22 and the bimetal 8.
- Protective gas welding of the second welding spot 25 securely connects bimetal 8 with an alloy that is very difficult to weld, thereby eliminating quality problems in this regard.
- the heating element 22 is welded to the passive side of the bimetal 8 with the shielding gas or plasma welding.
- the passive side of the bimetal 8 is well suited for welding, because only the active side consists of an alloy that is relatively difficult or impossible to weld.
- the lower end of the bimetal 8 is vertically connected to the yoke plate 28 on an outwardly bent tongue 33.
- the yoke plate 28 consists of a U-shaped area with two parallel side legs 29, 31, which hold the quick release, a cross leg 30 connecting these side legs 31 and a fastening section 32 and a tongue 33, which are integrally connected at right angles to the second leg 31.
- a fixing tab 35 is arranged on the fastening section 32 and projects into an elongated latching opening 36 with fixing knobs 37, as a result of which the yoke plate 28 is fastened in the parts carrier 5.
- the contact element 7 is arranged parallel to the fastening section 32, the trigger coil 38 being connected at one coil end to the contact element 7 with a third welding point 26, while the other coil end is connected to the yoke plate 28 at the fastening section 32 with a fourth welding point 27, where the current flow flows in regions through the yoke plate 28, ie flows from the fourth welding point 27 into the bimetallic spring 8.
- the contact element 7 is partially arranged in the yoke plate 28, the contact element 7 and the yoke plate 28 being provided with cutouts 39, 40.
- the contact element 7 is provided with a first section 41 which bears against the parts carrier and is provided with a recess 42 which engages in a support area 43 of the parts carrier.
- a second section 44 which is bulged in the area 45 and ends in an end section 46 arranged below the parts carrier 5, which is arranged in the same direction as the lower leg 18 of the connecting piece 6.
- a slot motor 47 is preassembled on the parts carrier 5 in the area 45 and in the vicinity of the end section 46.
- the parts carrier 5 is provided with two plate-shaped areas 49 which prevent the gases of the switching chamber of the switching device from reaching the triggering area.
- the contact angle 7 is pivoted into the parts carrier 5 behind the support region 43 by rotating about the axis X in the direction of arrow A in FIG. 2.
- the fastening lugs 3 protrude through the mounting openings 48 on the housing 12 into the receiving pockets 2 on the parts carrier 5.
- the current flow in the parts arranged on the parts carrier 5 flows from the lower leg of the connecting piece 6 to the first welding point 24, then into the heating element 22 to the second welding point 25, then via the bimetal 8 into the yoke plate 28 to the fourth Welding point 27, then into the trigger coil 38 up to the third welding point 26 and then into the contact element 7.
- the connecting piece 6 is mechanically fixed by the fixing pin 23 with the parts carrier 5, the yoke plate 28 with the parts carrier 5 by the fixing tab 35 and the contact element 7 with the parts carrier 5 on its support region 43.
- the heating element 22 and the trigger coil are held by the welding points 24, 25 and 26, 27, as a result of which all parts are held in a stable manner on the parts carrier 5.
- the parts carrier 5 is made of thermoplastic and is glued into the housing 12 or a housing part 13, like the other parts carriers of the other phases. The gluing takes place without an additional connection, such as screw connection or bracing and the like.
- the first pins 53 are each molded onto the yoke plate 28 while the second pins 54 are molded onto the connector 6.
- pins 53, 54 Only metal extensions of sheets are glued, which are marked here as pins 53, 54.
- the pins 53, 44 are spatially distributed to ensure a good hold. There are a total of nine pins 53, 54. This eliminates any screw connections that are otherwise required. The permanent, firm connection ensures that the bimetal position remains stable. Thermal and mechanical stresses are significantly reduced by gluing, while the thermal and dimensional stability is guaranteed.
- the trigger unit is integrated in the middle housing part 14.
- the preassembled parts carrier is inserted into the housing 12 in chambers provided for this.
- the slot motor (47) is a part made of an iron package or sheet iron, which supports the magnetic field in such a way that the contact bridge opens more quickly.
- the slot motor (47) is U-shaped.
