Fig. 1 has shown the partial view of opening according to the bottom of installation switchgear 1 of the present invention.Installation switchgear 1 (being line protection switch herein) often makes up with so-called shell-type structure (Schalenbauweise), also is kindred circumstances herein therefore.Installation switchgear 1 has case, and this case is assembled by two case half shells, and these two case half shells are in the assembling of the joint seamed edge place of annular.One of them case half shell is called bottom 101, and another case half shell is called top.In bottom 101, insert most of element, parts and the assembly of line protection switch.At the line protection switch shown in Fig. 1 to 4 basically corresponding to the line protection switch described in file DE 10 2,008 006863 A1.Therefore, file DE 10 2,008 006 863 A1 should be attached in the disclosure of the present invention aspect the structure of line protection switch 1 and the operation principle and aspect the structure of the switching mechanism of this line protection switch and operation principle.Therefore, in other description of the present invention, should no longer further inquire into switching mechanism, perhaps just when needs are used to explain object of the present invention.Certainly, yet the present invention is not limited to the application that utilizes as the switching mechanism as shown in file DE 10 2,008 006 863 A1, but is used in the switching mechanism of all types that can imagine in the installation switchgear of all types that can imagine on the contrary.
In the diagrammatic sketch of Fig. 1, the contact site of line protection switch is opened.The engagement lever 2 that has movable contact 6 deasil swings, away from fixing contact 7.Be air gap (Luftstrecke) between movable and fixing contact 6,7, no current can flow.Switching knob 5 is arranged in dissengaged positions, and the switch knob of this switching knob 5 is swung widdershins, and is arranged in the dissengaged positions that points to the left side.
In Fig. 1, also see pawl lever 103, dropout lever 104, connecting plate 3 and with the connection element 4 of clip (B ü gel) form.Between pawl lever 103 and dropout lever 104, form the locking position, as further explanation the among file DE 10 2,008 006 863 A1, locking in the state of locking position in being illustrated in Fig. 1.Switching knob 5 has jut 8, and this jut 8 is arranged in the opposite of switch knob 51.Jut 8 is connected with connecting plate 3 by connection element 4.
With respect to shown switching mechanism in file DE 10 2,008 006 863 A1, the device 10 that is used for fixing engagement lever 2 is for new.The device 10 for example in Fig. 5 and in Fig. 6 (with another form of implementation) illustrate as single-piece.Device 10 consists essentially of three parts.First parts are holding members 12, and this holding member 12 is connected with the 3rd parts (adjusting lever 14) by second parts (movable intermediate member 13).On the whole, device 10 probably has T shape, and wherein, holding member 12 and intermediate member 13 form the longeron of T
And adjust lever 14 and form short cross bar.
With the formal construction intermediate member 13 of contact pin, this contact pin is connected holding member 12 according to the type of flexible articulated elements with adjustment lever 14.Intermediate member 13 allows, and makes holding member 12 and adjusts lever 14 relative swing in the plane.Device 10 can manufacture be made of plastics articles injection-moulded in preferred form of implementation.Particularly advantageously, holding member, resilient intermediate member and adjustment lever are made by first and second materials with multi component injection molding technology together.At this, first material is to have high stable on heating wear-resisting raw material, and second material is the raw material that has high modulus of elasticity.Holding member 12 comprises first material, and intermediate member 13 and adjustment lever 14 comprise second material.
First material is to have high stable on heating wear-resisting raw material, for example by polysulfones (Polysulfone) (PSU), polyether sulfone (Polyethersulfone) (PES) or (PPSU) material made of family (Gruppe) of PPSU (Polyphenysulfone), also be the known material of trade name Ultrason.Second material is the raw material that has high modulus of elasticity, for example polyoxymethylenes (Polyoxymethylen) (is abbreviated as POM, also be called polyacetals (Polyacetal) or polyformaldehyde (Polyformaldehyd)), with the known material of trade name Delrin.
When the device 10 that will be used for temporarily fixing movable contact was assembled to installation switchgear, holding member 12 was in the zone of contact site.At this place, when handover operation,, the switching arc that forms raises owing to can causing the tangible temperature of short time.Therefore, advantageously, holding member 12 is made by having high stable on heating wear-resisting material.On the contrary, at intermediate member 13 with adjust in the zone of lever 14 importantly, even under the elastic force of bend loading and return, also can apply sufficiently high movement, long-time useful life, to turn back in the holding position for device 10 is moved once more.Therefore, advantageously, use the material that has high modulus of elasticity at this place.
For this reason, holding member 12 has the holding member matrix 16 that has slotted hole 17.Utilize slotted hole 17, holding member 12 remains on guide sleeve 18 places in half shell on case top 102 in displaceable mode.For this reason, guide sleeve 18 has the kayser lug of side direction, utilizes these kayser lugs with not tear-away mode (unverlierbar) kayser (verrasten) slide plate matrix 16, and wherein, slide plate can be shifted perpendicular to the front side 105 of case.The function of another of kayser is, avoids device 10 to drop with one in its parts and enters into device interior and contact with impact lever 109 at this place, so that its motion is not affected in the dropout situation or is not blocked at all.
Adjust that lever 14 has arm 20 and have the buttonhole 110 of maintenance at its first free end place.Thus, these adjustment lever 14 turntable supportings second be fixed in case the axle 19 places, this axle 19 is fastened in the case top.Be bent upwards at the second free end place arm 20 that is in maintenance buttonhole 110 opposites, so that produce crooked bumping surface 21 towards side edge of slide plate matrix 16, further be combined in switching knob 5 hereinafter and install the function that this bumping surface 21 is explained in interaction between 10 at it.
Deviate from the side edge of adjusting lever 14, forming maintenance jut 15 at holding member matrix 16 places.This maintenance jut 15 has approximate L shaped, this L shaped long leg points to downwards in the prolongation of intermediate member 13, and this L shaped short-leg perpendicular to (aufgespannt) plane that is stretched by holding member matrix 16 and therefore in the state of installing from the inner face of the inner face sensing case bottom 101 on case top.
Observe Fig. 2 now.This Fig. 2 shows such state, that is, make switching knob 5 deasil swing a segment distance in this state on the direction of on-state.Connecting plate 3 acts on the free end of engagement lever 2 in the mode that is driven by connection element 4 when the locking of the locking position of switching mechanism, and begins to make engagement lever 2 in swing widdershins on the direction of its closure state.At this, engagement lever touching keeps jut 15, and this maintenance jut 15 prevents engagement lever, further moves on the fixing contact 7.In the position that this stops, the spacing between fixing and movable contact 7,6 is so big, that is, make can not form electric arc between these two contacts.
When the position that makes switching knob 5 from Fig. 2 began further deasil to swing, then significant surface 11 was touched bumping surfaces 21.This position is illustrated among Fig. 3.
When switching knob still further deasil swung to on-state, switching knob 5 was adjusted lever 14 by its significant surface 11 based on being connected with bumping surface 21 effective upwards to push widdershins.Thus, holding device 12 utilizes and keeps jut 15 upward displacements, is directed in slotted hole 17.Device 10 reaches in its off-position, keeps jut upward displacement so far in this off-position, that is, make this maintenance jut discharge the motion path of engagement lever 2 suddenly.After this, snap close (schnappen) is in its closure state quite apace in the mode by 111 drivings of contact pressure spring for engagement lever 2, and movable contact leans against on the fixing contact in this closure state, and the contact site closure.At this, the so quick closure that must come in contact the position promptly, makes to produce electric arc.
At this, realize adjusting the upwards swing of lever against the prestressed returning place force of the device of having mentioned 10.Adjust lever 14 by swing, make middleware 13 further crooked.Middleware is implemented as spring-like resilient, and the elastic force of return that middleware is curved once more is straight.By mandatory guidance holding member 12 (this mandatory guidance only allows linear movement) and adjustment lever 14 (this mandatory guidance only allows to adjust lever 14 around its swinging axle swing in keeping buttonhole 110), straight the pushing of intermediate member 13 (Geradedr ü cken) can only be realized therefrom, that is, make holding member 12 be displaced in its holding position once more downwards.
When making engagement lever 2 when line protection switch 1 cuts off again, deasil swing in its off-position (see figure 1) once more by switching knob 5 is swung once more widdershins; then the jut 8 of switching knob discharges bumping surface 21 once more, and based on described relation hereinbefore holding member 12 is displaced in its holding position once more downwards.So, this holding member 12 prepares to be used for temporarily stopping engagement lever when reclosing.
As seen, holding member and intermediate member comprise metal gasket 117 in Fig. 5, and this metal gasket 117 is sealed by second plastic material is pressure injection-moulded.Metal gasket is as favourable dimensionally stable and improve intensity.This has reduced in frequent manipulation and the risk of the fatigue fracture in the zone at intermediate member during intermediate member frequent crooked thus.Metal gasket 117 is preferably made of steel.
