Description
Technical field
The utility model relates to a kind of aluminium electrolytic cell short-circuit port busbar voltage drop measurement mechanism.
Background technology
During electrolytic tank stops groove overhaul, stop the pressure drop of groove short-circuit opening and temperature and will measure in time and guarantee electrolytic series production safety.If stop groove short-circuit opening temperature exceeding standard or voltage over standard processes not in time, then black voltage increases, and not only causes the loss of electric energy, and cause short-circuit opening to damage, cause short circuit mouth for electrolytic bath to be blown out time serious, serious accident occurs, brings great loss to electrolysis production.Subsidiary factory's regulation potroom is weekly to stopping groove short-circuit opening temperature and drop measurement twice, and overhaul shop measures weekly 2 times, and equipment division measures weekly 2 times.Measured by subsidiary factory, workshop, teams and groups' " three grades ", the moment guarantee all stop groove short circuit mouth for electrolytic bath pressure drop and temperature in normal range.
Short-circuit opening busbar voltage drop uses multimeter to measure usually, but conventional test pencil intensity is poor, and test pencil surface easily oxidized (the usual test pencil life-span is only 3 months), causes the problems such as measuring speed is slow, read untrue.
There is certain potential safety hazard in traditional measurement method simultaneously, and traditional measurement method need two hands are held test pencil respectively and measured, and not only inconvenient operation, measures efficiency low, and once test pencil insulation goes wrong, bus current directly will pass through human body.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of aluminium electrolytic cell short-circuit port busbar voltage drop measurement mechanism, can measure aluminium electrolytic cell short-circuit port busbar voltage drop easily.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of aluminium electrolytic cell short-circuit port busbar voltage drop measurement mechanism; comprise handle 7; the front end of handle 7 is connected with the center of insulating protecting plate 2; handle 7 is provided with the fixed mount 4 for installing multimeter 6; two indicators 1 are symmetrically arranged with in the one side of insulating protecting plate 2; the tail end of each indicator 1 connects an indicator line 5 of multimeter 6 respectively by a corresponding copper lug 3, described copper lug 3 is positioned at the another side of insulating protecting plate 2.
The tail end of described handle 7 is provided with insulation sleeve.
The needle point of described indicator 1 is unsettled, and backshank arranges external thread, is assemblied on insulating protecting plate 2 by nut through after insulating protecting plate 2.
Compared with prior art, the beneficial effects of the utility model are:
1, this measurement mechanism extends indicator serviceable life.
2, this measurement mechanism indicator can avoid the unfavorable factors such as oxidation, distortion, measures accurately.
3, this measurement mechanism has good globality, and a single hand can complete measurement, improves measurement efficiency, reduces labour intensity.
4, this measurement mechanism provides twice insulation protection, improves and measures processing safety.

Embodiment
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
The present embodiment designs and produces for 180kA aluminium electrolytic cell short-circuit port bus, only needs the relative dimensions in corresponding change measurement mechanism design drawing for other electrolytic tank.
As depicted in figs. 1 and 2; a kind of aluminium electrolytic cell short-circuit port busbar voltage drop measurement mechanism; comprise handle 7; the front end of handle 7 is connected with the center of insulating protecting plate 2; handle 7 is provided with the fixed mount 4 for installing multimeter 6; be symmetrically arranged with two indicators 1 in the one side of insulating protecting plate 2, the tail end of each indicator 1 connects an indicator line 5 of multimeter 6 respectively by a corresponding copper lug 3, described copper lug 3 is positioned at the another side of insulating protecting plate 2.
Structure and the Main Function of each parts are as follows:
Indicator 1: adopt diameter to be φ 8mm stainless steel, length is 120mm.There is the advantages such as high strength, anti-oxidation, satisfactory electrical conductivity.Head is polished into pointed, can ensure to contact with bus perfection, and afterbody machining screw, and is fixed on after nut screw connection on insulating protecting plate 2.
Indicator line 5: the waste and old general test pencil line transformation of the way can be utilized.Waste and old test pencil line test pencil is excised, and this end is connected with copper lug 3, then copper lug 3 is anchored on the afterbody of indicator 1.Test pencil line 5 other end does not make and changes, and ensures good insertion multimeter 6.
Insulating protecting plate 2: adopt material to be phenolics plate, processing dimension is: long × wide × thick: (220 × 30 × 5) mm.It is the security protection of measurement mechanism first, well can stop the damage of electric current to multimeter and people.
Handle 7: front end is processed with screw thread, after utilizing nut lock, can well fixed handle 7 and insulating protecting plate 2.Afterbody adopts insulating material to make, and as second security protection, can ensure survey crew not by electric shock.Mounting and fixing support 4 on handle 7, is used for fixing multimeter 6 simultaneously, ensures the globality of measurement mechanism.
Multimeter 6: according to measuring object parameter, correctly chooses multimeter 6 and Reasonable adjustment gear.
As shown in Figure 3, during measurement, personnel hold device handle 7 indicator 1 are overlapped with short-circuit opening two side bus 8 respectively, and reading completes measurement.Concrete use procedure is as follows:
