The second conduction element 14 is provided with a circular hole 24 which makes the end of first conduction element 12 insert with gapless. The band 18 of the connecting device 16 welds a connector 44 of connecting flange 40 made of copper model on one hand, on the other hand welds a substrate 26 of main body of the second conduction element.
Description
The present invention relates to a kind of movable contact spare that is used to have the high pressure breaker protector of self-extinguishing expansion, comprise by assembling device with have the finger-type conductive contact that the jockey that flexibly connects band is connected.
File FR-A-2,556,511 have described a kind of movable finger contact of copper that is used to have the switch of three kinds of diverse locations.Each end of finger contact is provided with and is designed to the contact that matches with fixed contact that is connected to bus-bar or dead earth contact.What be used for lead-out terminal flexibly connects band by directly crimping on the circumference of finger contact of retainer ring.This movable finger contact is applicable to that maximum rated constant current is about switch or the breaker protector of 100A to 200A.
First purpose of the present invention is to realize a kind of movable contact spare that is used to have high rating electrical and high breaking electric capacity and has the breaker protector of self-extinguishing expansion.
Second purpose of the present invention is to improve the manufacturing of the movable contact spare of the breaker protector that is used to have self-extinguishing expansion, with when constant current by the time make pressure drop reduce to minimum.
Movable contact spare of the present invention is characterised in that finger contact comprises first conducting element and second conducting element with the main body that is become by the model copper of copper pipe form, second conducting element is provided with when skewer weldering operation and makes the end of first conducting element not have the circular hole that insert in the gap, and the binding post welding of the flange connector that the band that is characterised in that jockey becomes with the model copper is on the one hand welded with the substrate of the second conducting element main body on the other hand.
According to preferred embodiment, the circular hole of second conducting element is extended by the opening that the internal pipeline that makes pipe communicates with the outside.The opening of second conducting element is driveed to the outside from the main body facing to the connection substrate of band.The annulus skewer of being made by copper-tungsten is welded in facing on the pipe of the second conducting element circular hole.
When inserting, pipe is full of SF
6The arcing chamber of breaker protector with self-extinguishing expansion in the time, the air communication that produces in the arc extinguishing stage is crossed the internal pipeline of pipe and is discharged through opening.The setting of the relative band of opening has prevented that hot gas from also can keep the good insulation properties of breaker protector to any influence on the jockey.
Will understand other advantage of the present invention and feature by following more to only providing the description of the embodiment of the invention also shown in the drawings as limiting examples, wherein:
Fig. 1 is the overall perspective view of movable contact spare of the present invention;
Fig. 2 illustrates the perspective view of second conducting element of contact members among Fig. 1;
Fig. 3 is the axial cutaway view of Fig. 2.
With reference to Fig. 1, the movable contact spare 10 that is used for the high pressure breaker protector is designed to be connected with the actuator (not shown) of operating mechanism, and operating mechanism has three positions, i.e. second centre position and the 3rd earthing position opened of the contact primary importance of closing, contact.
Movable contact spare 10 forms the single subassembly of finger contact forms, and it comprises first conducting element 12, second conducting element 14 that the model copper becomes of copper coin column jecket 13 forms and has the jockey 16 that flexibly connects band 18.
Annulus 20 skewers of being made by copper-tungsten are welded in the free end of first conducting element 12, are welded in second conducting element 14 and manage 13 opposite end skewer, thereby form electric communicating continuously between two conducting elements 12,14.
Second conducting element 14 that is shown specifically in 3 at Fig. 2 comprises the main body 22 that become by the model copper, and it is provided with the circular holes 24 that inserted for pipe 13 before skewer weldering operation.On hole 24, have one to connect substrate 26, comprise two U-shaped recesses 28,30 of the end 32 that is designed to admit band 18.Circular hole 24 is extended by opening 34, and opening 34 side direction are opened downwards to outside and radially relative with connection substrate 26.
Jockey 16 is provided with model copper flange connector 40 and binding post 44, and flange connector 40 has the connecting plate 42 that is designed to be fixed in lead-out terminal, and binding post 44 is used for fixing the opposite end 46 of band 18.
The branch shape of band 18 is a U-loop, its end 32,46 preferably respectively be connected 44 welding of substrate 26 and binding post.
The assembling of movable contact spare 10 of the present invention and manufacturing are carried out in the following manner:
The skewer weldering of copper-tungsten ring 20 on copper pipe 13 both constituted the movable main contact that flows for constant current, constituted the movable arcing contact that rises that produces electric arc when breaker protector is opened again.When 24 places had been inserted in the hole, the other end skewer of pipe 13 was soldered on the main body of second conducting element 14 at second conducting element 14.
The end 46 of band 18 is welded in the binding post 44 of flange connector 40 then, and then, end 32 is welded in the substrate 26 of second conducting element 14.
Twice skewer weldering operation and twice welding operation are enough to obtain to prepare insert the single subassembly of the arcing chamber of breaker protector.Subsequently, actuator is connected with main body 22, makes movable contact spare 10 converting motion between three positions of breaker protector.Between this moving period, flange connector 40 is maintained fixed because of connecting plate 42 is stopped by screw, and the ring of band 18 is out of shape by the relative variation of branch length.
The use of movable contact spare 10 in the arcing chamber of the breaker protector with self-extinguishing expansion makes and can obtain air-flow by managing 13 internal pipeline 48.Undertaken by opening 34 to breaker protector cavity volume effluent air, it points to the opposite side of relative jockey 16.
