Aluminium Production Management
Today, Aluminium industry improves all its sectors of production to reduce losses and to boost system efficiency. One of the biggest problem coming across this new policy, when applied to production in line, is to decrease dependence on material. Rectifier, in regards to aluminium plant, is one of these centrepieces which must not be deficient in order to maintain production. The new lease of life taken by rectifiers balancing control equipment is very close to this new production management policy.
Rectifiers balancing
To satisfy its energy need, electrolysis industry implements power rectifier able to treat current about thousands amperes. To rectify such energy, these rectifiers are made up of different paths in parallel in order to dispatch the energy. The best performances of these rectifiers (efficiency, profitability, durability…) are achieved with a sharp balance of the different paths.
Prior COPORE equipment, the way to control the balance consisted to measure the intensity through the fuse with a grip current tester or with "Hall effect" sensor, these methods were too dangerous for the user and too inaccurate (bad synchronisation of the measures, sensors liable to external noise, overloaded sensors, filtering errors...). Now, with the COPORE equipment you will be able to measure the balance with high precision and high security.
Defective Rectifiers
A lot of problem can occur with such power equipment. First of all, and you will be surprised to know how many times it happens, rectifiers in new condition are not as perfect as you could think. In fact, the conception of one rectifier is strictly close to its final plant and therefore the risk of conception drift is serious. Means of evaluation were too archaic to estimate rectifier (with respect to specification of contract). Now, with a precision close to 1%, COPORE is the only one control equipment on the market able to resolve this problem.
A second problem (i.e. serie of problems) comes with time. Actually, rectifier characteristics are not stable. With current about thousands of amperes, the components of each path go through a bad time and their own characteristics (internal resistor, inductance component, threshold voltage) drift widely and unevenly with time. Therefore the share of the energy through the different paths becomes unbalanced. Without corrections this unbalanced share increases like an avalanche until partial or total destruction. In fact the best solution to maintain the balance is to know precisely what is the current through each path. COPORE is able to measures and displays 144 current signals synchronously, with its large number of tools COPORE will check up on the evolution of the rectifier.
COPORE & C.E.R
Fruit of 5 years of research and development, COPORE is the industrial version of the CER which has been adjusted and tested with ALUMINIUM-PECHINEY at several sites and now used as the standard measuring equipment to qualify rectifier. COPORE gives you the flexibility, the adaptability and the technological innovations of the CER with a precision adapted to the rectifiers balancing control for a range of temperature limited to the industrial needs and for a fair price.
Designed for precision, speed and accuracy, this new high technology measuring device consigns you all the secrets of electrical power system (improvement of the maintenance unit performance, reduction of energy losses, improvement of the all system efficiency, reduction of the maintenance costs).
Because COPORE is the only measuring device on the market, allowing a synchronous measure and a full management of its 144 possible channels; the new COPORE becomes the essential part for a structure which wants to be profitable and competitive.
More than just a measuring device, COPORE is a real equipment with concrete effects on rectifier efficiency. You will be able to evaluate, check-up, keep track of the equipment and therefore make real prevention.
