Description
Technical field
The present invention relates to the collocation method of aluminium electrolysis commutator institute direct current branch bus, particularly relate to the solution of the antimagnetic eddy current of a kind of indoor type aluminium electrolysis commutator institute's direct current branch bus.
Background technology
In the Aluminium Electrolysis process, low voltage need be provided, the direct supply of big electric current can satisfy production requirement, because the factor of aspects such as manufacturing capacity and running wastage, needing to form direct supply by a few cover rectifying devices powers to Aluminium Electrolysis, even the galvanic current that every like this cover rectifying device is exported may reach 60～100kA, when galvanic current is that the magnetic field that constant current produces is the stationary magnetic field, do not produce the magnetic eddy current around in the magnetizer, when having stray magnetic field in the direct current branch bus, can there be alternating magnetic field in the loop line that forms in the loop line that forms in the magnetic conductive metal member and the skeleton construction of reinforced concrete, this alternating magnetic field will produce bigger magnetic eddy current, this will form very big hidden danger, because the effect of magnetic eddy current will cause the heating of metallic conduction material in hardware and the reinforced concrete member, its temperature can reach more than the Baidu, this electrocorrosion will cause great harm to hardware and buildings, and cause the waste of the energy.This problem is bad as solving, and is very big to the structures influence of rectifier, therefore address this problem the safe operation of aluminium electrolysis commutator institute is very important, and this problem also is the technical barrier of solution that aluminium electrolysis commutator presses for always.
Summary of the invention
Technical problem to be solved by this invention provides the solution of the antimagnetic eddy current of a kind of indoor type aluminium electrolysis commutator institute's direct current branch bus, the present invention has adopted a kind of new direct current branch bus collocation method, can guarantee that direct current branch bus support can not form the magnetic loop line, solve several tons heavy support problem of direct current branch bus in 6 ~ 7 meters spans again.
The technical scheme of technical solution problem of the present invention is as follows: the solution of the antimagnetic eddy current of a kind of indoor type aluminium electrolysis commutator institute's direct current branch bus, in the both sides of every group of direct current branch bus the twice cement beam is set, many joist steel are set between cement beam, are connected with the insulating part that is used to support the direct current branch bus on the joist steel.
The upper limb of described cement beam and two layer planes are evened up, lower edge apart from floor level at 3.5～4 meters.
One end of described joist steel and the built-in fitting in the cement beam and angle steel welding, the other end load is on the grooved member that the built-in fitting with the cement beam opposite side reliably welds, and the end of this end of joist steel and with the contact surface of grooved member on, adopt the non-conducting material insulation.
Described grooved member is made up of three angle steel.
Described insulating part is a porcelain vase.
Advantage of the present invention and effect are as follows:
Cutting off the magnetic loop line is a practicable method that solves the magnetic eddy current problem, the present invention has adopted a kind of new direct current branch bus collocation method, can guarantee that direct current branch bus support can not form the magnetic loop line, solve several tons heavy support problem of direct current branch bus in 6 ~ 7 meters spans again.The present invention has improved the security of aluminium electrolysis commutator institute.Solved the harm that electrocorrosion causes hardware and buildings.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further explanation.
As depicted in figs. 1 and 2, the solution of the antimagnetic eddy current of a kind of indoor type aluminium electrolysis commutator institute's direct current branch bus, in the both sides of every group of direct current branch bus 1 twice cement beam 2 is set, the upper limb of cement beam 2 and two layer planes are evened up, lower edge between 3.5～4 meters, is provided with many piece joist steel 32 of cement beams apart from floor level, and direct current branch bus 1 is disposed on the joist steel 3, supported by insulating part 7, insulating part 7 is a porcelain vase.
The two ends of joist steel 3 all are arranged on the built-in fitting 4 of cement beam 2, and an end fixed form adopts welding, i.e. an end of joist steel 3 and the built-in fitting 4 in the cement beam 2 and angle steel 8 welding are as Fig. 3 and shown in Figure 6; The other end load is on the grooved members 5 that the built-in fitting 4 with cement beam 2 opposite sides reliably welds, as Fig. 4 and shown in Figure 7.
Finish by built-in fitting 4 and 5 welding of grooved member by the load-bearing problem that joist steel 3 loads form on grooved member 5.Joist steel 3 load is through on the grooved member 5 of magnetic treatment, joist steel 3 ends on the grooved member 5 and with the contact surface of grooved member 4 on adopt non-conducting material 6 to realize insulation.
