Description

Technical Field

[0001] The utility model belongs to the technical field of electrolysis data collection in aluminum electrolysis production, and particularly relates to a circuit conversion device for detecting a voltage of an electrolytic cell. Background Art

[0002] The 240KA series voltage data acquisition line in the electrolysis operation area 2 of Longxi Branch is in direct contact with the aluminum busbar. Due to the impact of the electrolytic cell effect voltage, carbonization occurs at the joint between the voltage value acquisition line and the aluminum busbar, and the conductivity decreases, causing a large error in the cell voltage collected by the cell control machine. At the same time, the upper computer shows that the operating voltage of the electrolytic cell is unstable and has large swings, which even affects the signal acquisition distortion of the adjacent cell control machine and affects the operation of the electrolytic cell. Utility Model Content

[0003] The purpose of the utility model is to provide an electrolytic cell voltage detection circuit conversion device to improve the stability and accuracy of the automatic operation of the cell control system.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A device for converting a voltage detection circuit of an electrolytic cell comprises a stainless steel bracket and an insulating plate arranged in the stainless steel bracket. The stainless steel bracket comprises a connecting plate and fixed plates symmetrically arranged at both ends of the connecting plate. Insulating plates are symmetrically arranged on the inner side walls of the fixed plates. The insulating plates are parallel to each other. Copper screws are passed through between the insulating plates. Double nuts are sleeved on the copper screws. One of the insulating plates is sandwiched between the double nuts.

[0006] In order to further realize the present utility model, the width of the stainless steel bracket is 30 mm, the height is 40 mm, the opening is 40 mm, and the thickness of the steel plate is 3 mm.

[0007] In order to further realize the present invention, the length of the insulating plate is 75 mm and the height is 50 mm.

[0008] In order to further realize the present invention, the copper screw is of model M16 and has a length of 65 mm.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The utility model adopts the principle of increasing the contact area and reducing the magnetic field interference. The copper wire and the aluminum busbar are connected by direct connection, which overcomes the problem of carbonization of the contact point, releases the effect of the effect voltage shock, increases the stability of the collected voltage signal, and can accurately reflect the operation status of the electrolytic cell.

[0011] The utility model can reduce the contact resistance to below 0.003 ohms and has strong stability. The contact resistance of the electrolytic cell voltage signal detector is ≤0.003 ohms.

[0012] The present invention can improve the stability of the cell control signal acquisition system, and the host computer can monitor the electrolytic cell in real time and accurately.

[0013] From the perspective of efficiency, the implementation of this project has greatly improved the stability of the voltage signal, solved the problem of easy carbonization at the contact point between the voltage acquisition line and the busbar, and reduced the safety hazards and labor intensity of maintenance personnel during the maintenance process.

[0014] From a technological and feasibility perspective, the device utilizes electromagnetic induction to release excess energy. It utilizes stainless steel for its brackets and insulating spacers for its copper screws, eliminating direct contact between the copper wire and the aluminum busbar. Its greatest advantage is that the slot controller can accurately collect voltage signals.

[0015] This renovation was carried out based on the original design and did not affect production. It was fully demonstrated before the renovation and is safe and reliable. It has excellent results in practical operation, is highly feasible, and has long-term benefits. BRIEF DESCRIPTION OF THE DRAWINGS
