Description
Technical field:
The present invention relates to be used in a kind of Aluminium Electrolysis the maintenance electrolyzer is carried out the short connector for electrolytic bath of electric current short circuit.
Background technology:
An electrolytic series often is connected in series more than 200 electrolyzer in aluminium manufacturer, arbitrary electrolyzer need stop groove overhaul or repair the back fluting to put into production, all to allow the big electric current of tens Wan An trainings be transformed on the bus of another platform trough from the bus of a platform trough, this conversion always relies on the set pressing-plate type short circuit mouth of each groove, require complete series power failure or load shedding more than ten minute during operation, otherwise can scaling loss short circuit mouth.As the mean lifetime of groove 5 years, annual overhaul groove reaches 40～50 approximately, stop every year in other words groove, the fluting reach 80～100 times, in some big aluminium manufacturer a plurality of electrolytic series are arranged, that is to say that annual requirement has a power failure or the operation of load shedding reaches hundreds of times, this frequent power failure or load shedding not only can cause serious detrimentally affect to electrical network, but also directly influence the output of aluminium and stablizing of production process.
At present, most of aluminium manufacturers all adopt the electric current short circuit of compression joint type short-circuit device realization to electrolyzer, it with bolt two rigid being crimped onto together of conducting plates, this compression joint type short-circuit device it seems that contact area is very big, the surface dig light but also flat not only, but from microcosmic, all have only several or tens some contact surfaces, its even curface can be singed at the arc light that moment produced that contacts with electrolyzer bus or break away from, electric current is in fact only concentrated flow through a limited number of point of contact, usually cause local superheating, even some point of contact freezed together, its cleaning polishing work of each operation back is all very heavy, the operator that also easily burn, this also just the compression joint type short-circuit device require the basic reason of under no-load or load shedding, operating.This compression joint type short-circuit device does not fundamentally solve electrolytic series and is not having a power failure, do not stopping groove and fluting problem under the load shedding situation.
Summary of the invention:
The objective of the invention is to: provide a kind of and can carry out charged short circuit, do not have a power failure the maintenance electrolyzer, not load shedding, do not influence the short connector for electrolytic bath of the normal operation of electrolytic series, to overcome the deficiencies in the prior art.
The present invention constitutes like this: it comprises short circuit inserted link (1) and short circuit device (4), and short circuit inserted link (1) is fixed on the negative electrode main bus-bar (3) of electrolyzer (2), and short circuit inserted link (1) connects short circuit device (4); Short circuit device (4) is placed on the insulator support (5), and hoisting appliance (6) is housed below insulator support (5), and hoisting appliance (6) is contained on the vehicle frame (7).
Short circuit device (4) is made of alloy box (8) and conductive metal sheet (9), short circuit inserted link (1) inserts in the alloy box (8), alloy box (8) is contained in the two ends of conductive metal sheet (9), in alloy box (8), be placed with low melting point alloy (10), quartz tube heater (11) is housed in the double wall of alloy box (8).
On the alloy box (8) of short circuit device (4), be provided with suppending hole (12), on the negative electrode main bus-bar (3) of electrolyzer (2), be provided with hanger bar (13).
The present invention adopts brand new concept and structure to replace the compression joint type short-circuit device of prior art, it replaces the solid-solid-state rigidity contact of prior art with the mushy stage contact, when just short circuit, alloy is in a liquid state, good fluidity, big with the contact surface of short circuit inserted link, contact, electric current is uniformly dispersed, and good electrical conductivity is arranged, and need not to grind, do not need the workman to touch electrical conductor, the danger of not burnt, and its are-tight anti-burning, even some distortion or damage do not hinder in excellent conducting performance yet.In short circuit, the liquid alloy condensation, welded together short circuit inserted link and short circuit device, have good welding electrical specification, pressure drop is low, loss is few, and in addition, the alloy under solid-state can be avoided volatilization and windfall loss.Compared with prior art, the present invention can not have a power failure, do not treat under the situation of load shedding and repair the electrolyzer short circuit, electric current is gone through bypass, load shedding not, do not have a power failure, do not influence the normal operation of other electrolyzers of electrolytic series and power network, also right when the electrolyzer serial connection after the reparation enters electrolytic series, fundamentally having solved electrolytic series is not having a power failure, do not stop groove and fluting problem under the load shedding situation, improved production efficiency, reduced production cost, and used flexibly, safe and efficient, simple to operate, carrying, easy to maintenance, it is few to be equipped with the platform number, per hundred electrolyzers only need be equipped with 6～8, with low cost, be easy to utilization and promote, but also cancelled the set devices such as short circuit mouth of each groove, vacate groove space letter on every side, changed the electrolyzer bus design.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the structural representation of short circuit device of the present invention.
Embodiment:
Embodiments of the invention: as shown in Figure 1, it comprises short circuit inserted link (1) and short circuit device (4), and short circuit inserted link (1) is welded on the negative electrode main bus-bar (3) of electrolyzer (2), and negative electrode main bus-bar (3) links to each other with the anode (14) of downstream electrolyzer.Short circuit device (4) is made of two alloy boxes (8) and a conductive metal sheet (9), conductive metal sheet (9) adopts the cast aluminium piece, short circuit inserted link (1) inserts in the alloy box (8), two alloy boxes (8) are contained in the two ends, the left and right sides of conductive metal sheet (9) respectively, in alloy box (8), be contained with low melting point alloy (10), its fusing point is equipped with quartz tube heater (11) in the double wall of alloy box (8) about 150 ℃.Short circuit device (4) is placed on the insulator support (5), and hoisting appliance (6) is housed below insulator support (5), and insulator support (5) is supported on the hoisting appliance (6) with high-tension porcelain insulator, and hoisting appliance (6) is installed on the removable vehicle frame (7).For ease of the suspension of short circuit device (4), on the alloy box (8) of short circuit device (4), be provided with suppending hole (12), and on the negative electrode main bus-bar (3) of electrolyzer (2), be provided with hanger bar (13).
