Abstract
The invention discloses a flexible connecting conductor, which comprises copper connecting ends at two ends, and a flexible connecting overlaying bodies consisting of a plurality of copper stranded woven belts in the middle. Both ends of the copper stranded woven belts are connected with the copper connecting ends respectively. The copper stranded woven belts are stranded by layers as follows: a plurality of circular copper lines with diameter theta smaller than or equal to 0.05 mm are stranded into a copper line unit strand, a plurality of copper line unit strands are stranded into a copper strand, and a plurality of copper strands are stranded into a copper stranded woven belt; the copper stranded woven belts in parallel form a copper strand woven belt layer, and the copper strand woven belt layers are overlaid up and down to form the flexible connecting conductor with a rectangular cross section. According to the flexible connecting conductor, the flexibility of the flexible connecting conductor is greatly improved, the moving resistance of a busbar of a moveable contact is further reduced, the switching force and the switching maintaining force are reduced, the switching speed is improved, and the service life of high-low voltage electric equipment is prolonged.
Description
Technical field
The present invention relates to a kind of high-low-voltage electrical equipment and the bonding conductor that inputs or outputs copper bar, particularly a kind of movable contact bus bar and the conductor that is flexible coupling that is connected the copper bar connection for DC high speed circuit breaker belong to the power supplying and distributing equipment technical field.
Background technology
The conductor that is flexible coupling be widely used in high and low voltage electrical equipment, vacuum circuit-breaker and High-low voltage switch cabinet be connected movable contact bus bar with input or output being connected of copper bar, the high-quality circular copper wire twisting that the existing conductor employing wire diameter that is flexible coupling is Φ 0.10mm, Φ 0.15mm or Φ 0.20mm is woven into the single layer weaving belt wide with the connection end at its two ends, single layer weaving belt in layer is overlapped into up and down the superimposed body that is flexible coupling, satisfying the cross-sectional area requirement of the conductor that is flexible coupling, and reach dc resistivity (20 ℃) and be not more than 0.022 Ω .mm
2The electric property of/m, will be flexible coupling at last superimposed body two ends and connection end mold pressing link into an integrated entity.The braid over braid number of plies of the superimposed body that is flexible coupling that existing cross-sectional area is larger is few, the circular copper wire wire diameter of braiding is thicker, and pliability is obviously relatively poor, causes the movable contact bus bar moving resistance that is connected with the conductor that is flexible coupling larger, affect switching force and closing retention force, also affect divide-shut brake speed; In addition, the existing conductor two ends that are flexible coupling are respectively with movable contact bus bar and input or output the difficulty that is linked and packed relatively of copper bar.
Summary of the invention
The object of the present invention is to provide that a kind of cross-sectional area is large, pliability is flexible coupling conductor preferably, reduce the moving resistance of movable contact bus bar.
Purpose of the present invention is achieved by the following technical programs:
A kind of conductor that is flexible coupling comprises the superimposed body that is flexible coupling that the copper connection end at two ends, many middle copper stranded conductor braid over braids form, and described many copper stranded conductor braid over braid two ends pack into respectively in the copper connection end, link into an integrated entity by mold pressing and copper connection end; Described copper stranded conductor braid over braid forms according to following level is stranded: the circular copper wire of many wire diameter Φ＜=0.05mm is twisted into 1 copper cash unit thigh, and several copper cash unit thighs are twisted into 1 copper cash thigh, and a plurality of copper cash thighs are twisted into 1 copper stranded conductor braid over braid; Many copper stranded conductor braid over braids consist of copper stranded conductor braiding belt side by side, and a plurality of copper stranded conductor braiding belts up and down superimposed composition cross section are the superimposed body of being flexible coupling of rectangle.
The aforesaid conductor that is flexible coupling, the scope of wherein said circular copper wire wire diameter Φ is 0.015 mm～0.05mm; The copper cash of 54～58 Φ 0.05mm wire diameters is twisted into 1 copper cash unit thigh; 3～5 copper cash unit thighs are twisted into 1 copper cash thigh; 17～20 copper cash thighs are twisted into 1 copper stranded conductor braid over braid; The copper stranded conductor braid over braid sum of the described superimposed body that is flexible coupling reaches 100～104.
The aforesaid conductor that is flexible coupling, wherein the copper connection end of an end is the level connection joint end, the copper connection end of the other end is vertical link.
The invention has the beneficial effects as follows: compare with the existing conductor that is flexible coupling that is consisted of by superimposed up and down multiple layer of copper twisted wire braid over braid, because circular copper wire wire diameter of the present invention is less, consist of the copper stranded conductor braid over braid sum of the superimposed body that is flexible coupling much larger than the copper stranded conductor braid over braid number of plies of the existing conductor that is flexible coupling, greatly improved the pliability of the conductor that is flexible coupling, further reduced the moving resistance of the movable contact bus bar that connects, switching force and closing retention force have been reduced, improve divide-shut brake speed, prolonged the useful life of high and low voltage electrical equipment equipment.
Advantage and disadvantage of the present invention will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is schematic perspective view of the present invention.
Embodiment
Be 630mm below in conjunction with accompanying drawing and cross-sectional area
2The embodiment of the superimposed body that is flexible coupling the invention will be further described.
As shown in Figure 1, the first end of copper link of the present embodiment is that level connection joint end 1, the other end are vertical link 2, so as respectively with corresponding movable contact bus bar be connected copper bar and be connected.Level connection joint end 1 is 6.2mm with the vertical link 2 middle superimposed bodies 3 that are flexible coupling by every cross-sectional area
2102 copper stranded conductor braid over braids 31 form, level connection joint end 1 and the vertical end 2 that connects adopt copper pipes to make, 102 copper stranded conductor braid over braid 31 two ends pack into respectively in level connection joint end 1 and the vertical link 2, use the forcing press mold pressing, so that flat link 1, vertical link 2 and superimposed body 3 two ends that are flexible coupling link into an integrated entity.
Copper stranded conductor braid over braid 31 forms according to following level is stranded: 56 circular copper wire wire diameters are that Φ 0.05mm circular copper wire is twisted into 1 copper cash unit thigh, 3 copper cash unit thighs are twisted into 1 copper cash thigh, 19 copper cash thighs are twisted into 1 copper stranded conductor braid over braid 31,17 copper stranded conductor braid over braids consist of 311,6 layers of copper stranded conductors braiding of 1 layer of copper stranded conductor braiding belt belt superimposed composition superimposed body 3 that is flexible coupling about in the of 311 side by side.
Also can further reduce the circular copper wire wire diameter, select wire diameter to can be Φ 0.015mm～Φ 0.03mm.With the be flexible coupling pliability of superimposed body 3 of further raising, further reduce the moving resistance of movable contact bus bar.
