[0002] At present, in the design of lead, copper and other electrolytic equipment, in order to use rectifiers more effectively to achieve the purpose of energy saving and production increase, multiple tanks are often used in series in the design and application. In the production process, single tanks need to be loaded and unloaded, and when local electrolytic cells need to be repaired, they need to be powered off for maintenance. However, since multiple tanks are grouped in series, they often lose power at the same time when the power is cut off. Since the power outage will cause more consumption of the circulating liquid, and some pumps and other configuration equipment have to bear more operating tasks, once the power outage is too long, it will affect the output and the quality of the cathode.
[0003] In order to ensure that the production process does not affect the normal electrolysis of other electrolytic cells, a single-slot short-circuit breaker is particularly necessary. The current single-slot circuit breakers are mostly composed of copper bars, copper plates, copper blocks and copper jackets as contact points. They are heavy, inconvenient to move back and forth, and difficult to operate. In addition, there is no fixing device between the circuit breaker and the busbar copper bar. The contact is only carried out by stacking. The copper bar connecting device is not in close contact with the busbar copper bar, and it is easy to be disconnected due to contact. The stability of the circuit connectivity of the entire short-circuit device cannot be guaranteed, and there is a safety hazard. Summary of the invention

Two upper and lower corresponding hard copper bars 7 are arranged on both sides of the transverse electric switch 5, and a hard connecting plate 6 is fixedly arranged between the ends of the two hard copper bars 7 away from the transverse electric switch 5. The hard copper bar 7 is arranged on the placement rack 4, and one end of the hard connecting plate 6 extends out of the two hard copper bars 7, and a short-circuit trolley soft connecting plate 8 is fixedly connected between them. The hard copper bar 7 is connected to the hard connecting plate 6 by bolts, and the position of the short-circuit trolley soft connecting plate 8 is adjusted by the bolt connection to adapt to the busbar copper bar 2 at different distances, and the hard copper bar 7 can also adjust the extension length.

[0023] Each end of the short-circuit trolley flexible connection plate 8 is stacked up and down with the end of the corresponding busbar copper bar 2 and connected by a clamping device, the clamping device includes a locking detection device, a horizontal gasket 9, a clamping screw 10 and a support arm 11, the locking detection device is fixedly connected with two U-shaped support arms 11 surrounding the side of the busbar copper bar 2, the two support arms 11 are symmetrically arranged about the elastic locking transposition, the two support arms 11 surround the stacked busbar copper bar 2 and the short-circuit trolley flexible connection plate 8, A threaded barrel 12 is fixedly connected to the lower end of the support arm 11, and a clamping screw 10 is connected to the inner thread of the threaded barrel 12. A horizontal gasket 9 is fixedly arranged above the clamping screw 10. The horizontal gasket 9 is located below the busbar copper bar 2 and corresponds to the locking detection device up and down. A screw handle 21 is arranged below each of the clamping screws 10.
