Abstract
The utility model provides a vertical post busbar compression jointing structure of an aluminium cell, comprising a soft busbar, two soft busbar connectors, a vertical post busbar, a vertical post busbar terminal, a tapped stud and a screw cap. The compression jointing structure is characterized in that (1) the cross sections of the two soft busbar connectors are right-angled triangles, the bevel edge of the right-angled triangle faces to the vertical post busbar terminal; and (2) the cross section of the vertical post busbar terminal is isosceles trapezoid, and the isosceles part of the trapezoid is parallel with the bevel edges of the soft busbar connectors. The bevel connection is adopted between the soft busbar connectors and the vertical post busbar, thereby evidently increasing the contact area, reducing the contact resistor correspondingly, and reducing the voltage drop at the connecting position of the vertical post busbar and the soft busbar. The proposal has the advantages of delicate design, reasonable structure, convenient operation, evident improvement on the electricity conducting performance, and great popularization value.
Description
Technical field
The utility model belongs to the technical field of the current supply arrangement of aluminium cell, is specifically related to a kind of aluminum electrolytic cell riser bus bar compression joint device.
Background technology
At present, aluminum electrolytic cell riser bus bar top all is to take the crimping mode to carry out with the connection at the soft bus of anode place usually.Wherein soft bus is divided into two groups, its cross section of two groups joint become relatively to trisquare shape, cross section, bus column termination corresponding with it then is a rectangle.During installation, two set of joints of soft bus are clamped the termination of riser bus bar from both sides, with threaded stud, nut fastening after, just connecting as one with riser bus bar and soft bus success.For the conductivity that makes above-mentioned two bus-bar compression joint surfaces improves, Chinese patent ZL200420060183.8 has proposed a kind of " riser bus bar syndeton ", and an aluminium sheet is welded on every limit at least on the dual-side of soft busbar joint and riser bus bar joint, its bonding crack.Yet this structure must unload threaded stud more earlier with under the aluminium sheet shovel that is welded when overhaul, riser bus bar and soft bus could be taken apart.The other two blocks of aluminium sheets of also will burn-oning again when refilling groove.Such design, the complexity of its operation is apparent, and, this two blocks of unnecessary aluminium sheets of burn-oning, only may increase riser bus bar, reduce the contact resistance between riser bus bar and the soft busbar joint till the ass ascends the ladder, thereby also just do not reach its desired effect with the contact resistance between the soft bus.
The utility model content
The utility model purpose be propose a kind of simple in structure and can make the improved riser bus bar compression joint device of conductivity of crimping face between riser bus bar and soft bus two joints.
Aluminum electrolytic cell riser bus bar compression joint device of the present utility model comprises soft bus, soft busbar joint, riser bus bar, riser bus bar termination, threaded stud and nut, it is characterized in that:
The cross section of (1) the two soft busbar joint trilateral that meets at right angles, its hypotenuse subtend riser bus bar termination;
(2) cross section of riser bus bar termination becomes isosceles trapezoid, and its trapezoid two waists parallel with the hypotenuse of soft busbar joint.
Aluminum electrolytic cell riser bus bar compression joint device of the present utility model, because taked the connection on inclined-plane between soft busbar joint and the riser bus bar, its contact surface has tangible increase, after contact surface increases, contact resistance is corresponding to be reduced, thereby has also just reduced the volts lost of riser bus bar and soft bus junction.
Aluminum electrolytic cell riser bus bar compression joint device of the present utility model for when mounted, makes soft busbar joint with locating better between the riser bus bar termination, also the acute angle of soft busbar joint right-angle triangle front end can be clipped, and forms a plane; Correspondingly, reserve two chain-waless in both sides, riser bus bar termination.Marquis when soft busbar joint and riser bus bar termination are crimped on together with threaded stud, nut, chain-wales is just in time with the facet wringing fit of soft busbar joint, can not produce tangential slippage because of stressed.
Aluminum electrolytic cell riser bus bar compression joint device of the present utility model, deft design, simple in structure, easy to operate, and, have very big promotional value for the improvement highly significant of its conductivity.
Description of drawings
Fig. 1 is aluminum electrolytic cell riser bus bar and soft bus-bar compression joint structural representation, and Fig. 2 is the local enlarged diagram of aluminum electrolytic cell riser bus bar termination and soft busbar joint compression joint device.Among above-mentioned two figure: the soft bus of 1 anode; 2 soft busbar joints; 3 riser bus bars; 4 riser bus bar terminations; 5 threaded studs; 6 nuts, Θ then are that soft busbar joint right-angle triangle colludes the angle between the chord.
Embodiment
Below in conjunction with accompanying drawing design of the present utility model is further described and replenishes.
As shown in Figure 1, 2, right-angle triangle is made, hypotenuse subtend riser bus bar 3 terminations 4 in two of present design soft bus 1 joints 2 its cross sections; And the cross section of riser bus bar termination becomes isosceles trapezoid, and these trapezoidal two waists parallel with the hypotenuse of soft busbar joint.Have more than one hole on soft busbar joint and the riser bus bar termination, threaded stud 5 is passed above-mentioned hole, fixing getting final product tightened with nut 6 again in its two.When design, the angle Θ that colludes between the chord for soft busbar joint right-angle triangle can get different numerical value, can make the resistance of soft busbar joint and riser bus bar termination obtain reducing in various degree thus, also just can improve its conductivity in various degree.
Embodiment 1 Θ is the situation of 45
Getting the Θ angle is 45 °, under the certain situation of right-angle triangle section chief (A), chord length (C) should be according to the trigonometrical function relation: C=A/Sin Θ=A/Sin45 °=1.414A, so, this moment, soft busbar joint increased 41.4% with the contact area of riser bus bar termination, correspondingly, it is about 41.4% that contact resistance then will reduce, and the improvement of conductivity is very remarkable.
Getting the Θ angle is 60 °, and with 30 ° of right-angle triangle (string, strand between angles) the tip cut, form a facet, reserve corresponding chain-wales in isosceles trapezoid both sides, riser bus bar termination accordingly.Under the certain condition of right-angle triangle section chief (A), chord length (C) should equal: C=A/Sin60 °=1.154A, so the time, the contact area of soft busbar joint and riser bus bar termination has increased by 15.4%.Correspondingly, it is about 15.4% that contact resistance will reduce, and power savings is considerable.
Embodiment 3 Θ are the situation at 75 ° of angles
Getting the Θ angle is 75 °, and then under the constant prerequisite of right-angle triangle section chief (A), chord length (C) should equal: C=A/Sin75 °=1.045A, at this moment, soft busbar joint has increased 4.5% with the contact area of riser bus bar termination, and contact resistance reduces 4.5%, and it is passable that power savings also can be said to be.
From above-mentioned three embodiment, the span at Θ angle can for: 45 °＜Θ＞75 °, but from material pin consumption with save energy many-side and take all factors into consideration, should be the optimum valuing range at Θ angle then with 60 ° ± 5 °.
