Further specify as follows to a kind of electrolysis of the utility model with the mode of installing and using and structure, function, principle, the effect of the described embodiment of short switch:
The utility model switch is installed in the electrolysis tank loop, and hard copper has been got rid of and has been used to be electrically connected, and also will play the effect of installing of supporting.Earlier main contact 37 usefulness dog screws 38 bolts are arranged on 18 at hard copper, the centre press-fits rubber sleeve 17, and the two has increased contact area for conical surface contact, helps bearing great current.Support structure 20 is welded by corrosion resistant plate, is the skeleton of switch.The hard copper row 18 that main contact 37 has been installed is passed through insulating pad 19, insulation cushion 40, on support structure 20, hard copper row 18 is connected with support structure 20 insulation with bolt 39 bolts.On special-purpose installing rack, hard copper row 18 plays the effect of support in installation process with the other end bolt that is installed in the hard copper row 18 on the support structure 20.Lower shoe 21 bolts are on support structure 20, and it is the basis of switch motion mechanism.The main contact that is installed on the hard copper row 18 is quiet main contact, and the moving main contact of main contact system partly is installed in and is flexible coupling on 16.In installation process; to move main contact 37 bolts with fixed lever 36 by plate 15 tightly is being flexible coupling on 16; rubber sleeve 17 is pressed in moving main contact simultaneously and is flexible coupling between 16, and 17 pairs of main contacts of rubber sleeve have prevented the pollution of money base main contact effectively to forming airtight protection like this.The other end that is flexible coupling is fixed on the special-purpose installing rack simultaneously.All main contacts are to equal mounted in pairing mode.Being in being flexible coupling of support structure 20 the same sides is installed in the moving main contact push pedal 12.Moving main contact push pedal 12 is fixed with insulating case 33 by dynamic pressure jack panel 32, effectively isolates with the fixed lever 36 and 16 electricity that are flexible coupling.The effect of moving 12 pairs of moving main contact power of main contact push pedal realizes that by dish spring 34 dish spring 34 1 ends act in the moving main contact push pedal 12, the other end by packing ring 35 act on be flexible coupling on.The end of fixed lever 36 has self-locking nut 31, can regulate the excess of stroke of main contact.During switch motion, dish spring 34 compressive deformations provide enough pressure to the main contact contact-making surface, have guaranteed the through-current capability of main contact.Dish spring 34 and self-locking nut 31 have dish spring cover 14 and dust cover 13 protections, guarantee its good working order.
The utility model electrolysis with the characteristics of short switch actuating mechanism is:
By eccentric wheel structure the straight line that the rotation of six square shafts 11,22 has been transformed into moving main contact push pedal 12 is moved.Six square shafts are clockwise or be rotated counterclockwise certain angle (90 °), and moving main contact push pedal 12 will drive main contact disconnection and closed.Concrete realization is: driven six square shafts 22 are fixed on upper plate 7 by positioning sleeve 29 and go to the bottom and pull between 21, eccentric wheel 41 is sleeved on six square shafts, simultaneously, eccentric wheel 41 is embedded in the driver plate 8 by bearing 42, and the other end of driver plate 8 and moving main contact push pedal 12 cooperate together by axis hole.Necessary parts such as packing ring 9, clip 10, packing ring 30 have also been comprised in the mechanism.Like this, six square shafts drive eccentric wheel 41 and rotate, and driver plate just drives moving main contact push pedal 12 straight lines and laterally moves.Initiatively six square shafts, 11 ends are also like this.Two six square shafts have trace 6 to connect, strict guarantee same tropism two six square shafts motions the time, this makes the main contact synchronization action that assurance arranged.The drive source of moving main contact system from drive motors 2, it is installed in the top of switch by motor pedestal 4, drives the action of six square shafts by connector.Switch does not have special locking and maintaining body, and the confining force during switch closure is provided by drive motors and reducing gear thereof.The drive motors outside is equipped with motor cover 1, can effectively protect motor not to be subjected to the influence of outside abominable operational environment.The minor arc sequencing control of short switch and logic is chain is finished by PLC.Air type arc quenching system 24 is installed in the top of short switch, is attempted by the both sides of short switch main contact system with being flexible coupling during use.Travel switch 5 and connecting terminal block 3 are installed on motor pedestal 4.When six square shafts rotated, the 25 pairs of travel switches of travel switch location-plate 5 that are fixed on active six square shafts 11 were done in order to produce the main contact closure or to disconnect the signal that puts in place.The action of switch and arc system and status signal all are connected to the external dedicated control cabinet through connecting terminal block 3, gathered, are handled and judge by PLC, provide action command.The minor arc system of switch has just broken away from mechanical contact on action sequence like this, the difficulty that this greatly reduces assembling, and the fault mode that has reduced switch burns and connects being flexible coupling of minor arc.This greatly facilitates the maintenance and the maintenance of switch.This switch is that suspension type is installed.In the switch bottom, initiatively be fixed with on off state pointer 27 on six square shafts 11, it rotates with six square shafts, by its position of indication on off state direction board 26, can be easy to distinguish the switch current state.
During actual the use, short switch hangs and is installed on electrolysis tank master or the duplexure bus.When the needs switch closure, PLC can be in certain sequence, the closed air type arc quenching system 24 of elder generation, after receiving the signal that puts in place of air type arc quenching system, give drive motors 2 actuating signals again, rotate initiatively six square shafts, closed main contact system, put in place behind the signal when detecting main contact closure that travel switch 5 sends, cut off the actuating signal of drive motors 2, so far finish the closed action of switch.When the needs switch disconnected, PLC can disconnect main contact earlier, after the affirmation main contact disconnects, disconnected the arcing contact system.In the process of short switch closure, as not action or not at closure state, then PLC forbids the main contact closure of air type arc quenching system 24; In the disconnection process, there is not disjunction to put in place as main contact system, then PLC forbids that air type arc quenching system 24 disconnects.This strict guarantee the main contact system safe action.Air type arc quenching system 24 has very strong breaking capacity and stronger through-current capability.Even, main contact system disconnects in the disconnection process, and air type arc quenching system 24 does not move or closing course in, air type arc quenching system 24 closures and main contact system does not move, also only can burn and connect being flexible coupling of minor arc system, the fault mode that this has significantly reduced switch has reduced economic loss.Because the effect of short switch, to the separate unit cell maintenance with repair the continuation production that can not have influence on other electrolysis tank, this to energy-saving and cost-reducing, stable electrical network operation, improve the electrolytic production quality and all have very significant practical function.
The utility model scope of patent protection is not limited to the foregoing description.
