Embodiment 1.
1, the design of part flow arrangement
Realizing does not have a power failure stops the groove operation; A most important job is the shunting short circuit that carries out potline current, is interior inclined because the short circuit mouth of electric 180KA electrolyzer is advanced at two ends, the space that part flow arrangement is not installed; Do not possess operability yet, therefore must the corresponding part flow arrangement of design.Advance the characteristics of electrolyser according to two ends; With the part flow arrangement Position Design between operation slot horizontal bus 10 and the downstream slot horizontal bus 1; Operation for the ease of part flow arrangement; Design and installation disconnection, close switch in the middle of part flow arrangement, therefore a component stream device just is made up of four parts: the operation slot side connects busbar 8, transition copper coin 5, commutation switch 6, downstream slot connection busbar 4.As shown in Figure 1;
Connect busbar such as Fig. 2-shown in Figure 3, be convenient to easy for installationly, a high position is connected busbar 4 is connected busbar 8 and horizontal bus with low level crimping plate be designed to two; Big crimping plate 16 is main web plate, and little crimping plate 17 is auxiliary web plate, and big crimping plate 16, little crimping plate 17 and extension web plate 18 are connected; Extending web plate 18 is connected with adjustable copper bar 19; Adjustable copper bar 19 is to be made up of the multilayer copper sheet, can carry out the front and back adjustment of copper bar and move, and is convenient to when mounted laterally adjust with the relative position of commutation switch 6; Be protection multilayer copper sheet; Also increase simultaneously the hardness of adjustable copper bar 19, a cover backplate 20 has been installed on adjustable copper bar 19 tops, tear damage to prevent adjustable copper bar.Adjustable copper bar 19 front ends have connected a stripe shape web plate 21 through crimping bolt 23, and stripe shape web plate 21 is when operation and the rebound crimping of commutation switch.It is identical with operation slot connection busbar 8 that downstream slot connects busbar 4 structures; Two connect busbar when mounted respectively with 5 crimping of transition copper coin; Transition copper coin 5 is connected with commutation switch 6, but forms the current return of break-make, carries out the shunting of electrolyzer; For improving the streaming rate that connects busbar, all crimping plates are copper in the busbar.Because the high-order overall dimensions that connects busbar 4 is bigger, be copper simultaneously, weight is heavier, makes things convenient for handling in order to install, and connects busbar 4 tops in a high position two suspension ring 22 of specializing in lifting have been installed, and lifting is used during for operation.For adapting to the lifting that high-order height distance and the low level that connects between busbar 4 and the adjacent downstream groove anode large bus bar 1 is connected busbar 8, the present invention is provided with the downstream slot balance sling 3 that is exclusively used in high position connection busbar 4 and is exclusively used in low level and is connected the operation slot balance sling 9 of busbar 8.
In process of production; The horizontal bus position of every electrolyzer is not on a sea line; Between adjacent slot, also there is one high and one low phenomenon; Therefore in the design that connects busbar, in order to make connection busbar after the installation as far as possible on a sea line, just will connect busbar and be designed to two groups: i.e. high position connection busbar 4 is connected busbar 8 with low level.The high-order busbar 4 that connects is installed in the higher bus bar side of level when operation, low level connects busbar 8 and when operation, is installed in the lower bus bar side of level, and the connection busbar that so just can as far as possible make both sides is convenient to connect in a sea line.
Electric current disjunction part: electric current disjunction part is that downstream end transition copper coin 5 is formed with low level transition copper coin 37 by commutation switch 6 and two transition copper coins mainly, and downstream end transition copper coin 5 is to be fixedly connected with low level transition copper coin 37 with commutation switch, can not split.The main effect of downstream end transition copper coin 5 and low level transition copper coin 37 is to be connected busbar 4 to be connected busbar 8 with low level and to carry out crimping with a high position; In order in the crimping process, can better to contact; Downstream end transition copper coin 5 is bigger with low level transition copper coin 37 width; For connecting 2 times of busbar, just be connected busbar 8 with low level and carry out up and down adjustment highly to be connected busbar 4 with a high position.
Commutation switch 6 is made up of switch framework 27, permanent mechanism driving mechanism 28, cable connector plug 29, switch trace 30, sound main contact 31, travel switch 32, sound arcing contact 33 etc.; As shown in Figure 4; Effect is exactly in the shunting process, carries out the short circuit and the disconnection of electric current.Because every group of electric current be big (being about 45KA), thus the inner layouts that adopt the parallel connection of many group contacts of switch, being damaged by electric arc in order to prevent the main switch contact system, commutation switch is designed with main, two grades of contacts of arc.When commutation switch was closed, the arc system was closed earlier, and is closed behind the main contact; During the commutation switch disjunction, the disjunction of host system elder generation, disjunction behind the arcing contact.Arc energy consumes in the arcing contact system, with reliable contact and the low electric cloudy characteristic that guarantees main contact, can protect the main switch contact system effectively like this.
2, the design of the integrated auxiliary erecting stage of multiple degree of freedom
On the operation slot groove on horizontal bus 10 and the downstream slot groove neighbor distance value of horizontal bus 1 be 5300 ㎜; But owing to the PT differs; The groove upper level bus of most electrolyzer squints; Therefore the distance between two groove horizontal bus exists than mistake, is approximately 5300 ㎜ ± 30mm through statistics; The anode electrolytic cell lift makes it, and vertically height is mobile in the 300mm scope; And style plate flatness and absolute altitude all have than mistake; Equipment is placed on the style plate and lifts connection; Commutation switch 6 must be placed on six-freedom degree all can quick-adjustsing auxiliary erecting stage 7 on, can adjust fast and be connected, otherwise installation work will lose Practical significance because of efficient is extremely low.
Erecting stage 7 is as shown in Figure 4; Be made up of steel framed structure, main effect is to support commutation switch 6, and commutation switch 6 is fixed on the top of platform; The platform middle part is provided with two chain-waless 36; Be used for operator and carry out rebound and be connected the busbar crimping operation above stepping down in, also can after commutation switch 6 actions, observe commutation switch 6 break-make situation.Adjustable whole equilibrated wall screw 24 is equipped with in the platform bottom; Carrying out platform adjusts along the balance on the plate at groove; The platform middle part is equipped with hydraulic pressure and rises device, that is: commutation switch 6 bottoms connect guidepost 14, and erecting stage 7 is provided with pilot sleeve 15; Guidepost 14 is hinged with hydro-cylinder 12 after inserting in the pilot sleeve 15, and hydro-cylinder 12 all is connected on the erecting stage 7 with Hydraulic Station 13.When downstream end transition copper coin 5 and low level transition copper coin 37 connect busbar 8 relative positions when low with high-order busbar 4 or the low level of being connected, can pass through hydraulicefficiency plant on the erecting stage 7 with commutation switch 6 jack-up, connect; When downstream end transition copper coin 5 and low level transition copper coin 37 connect busbar 8 relative positions when higher with high-order busbar 4 or the low level of being connected, can commutation switch 6 be put down through the contraction of the hydro-cylinder on the erecting stage 7, connect.
