Description
Technical field
The present invention relates to a kind of charged used device of method that carries out stopping and opening electrolytic tank, belong to direct current hot line work technical field.
Background technology
In the production of electrolytic aluminum, many electrolyzers are as being to be connected after the series connection on the direct supply of low-voltage and high-current with electrical load.As everyone knows, when series circuit occurred opening circuit when one of them load, other load also can not be worked because of outage.Because the particular requirement of electrolyzer; Need regular one or more electrolyzer being stopped groove overhaul or slot to start;, certain electrolyzer, in the feed circuit of every electrolyzer, is designed with the short-circuit busbar parallelly connected when stopping groove or fluting with electrolyzer in order not influence the works better of other electrolyzer.Short-circuit busbar is realized current switching through the closed and disconnected of column and short-circuit block.Because the power supply of electrolyzer is the direct supply that adopts low-voltage and high-current, in the process of the closed and disconnected of column and short-circuit block, understands the very high electric arc of generate energy even blast.Abnormally dangerous during operation, may cause damage or operator are caused personal injury power-supply unit.
The common traditional method of current switching of realizing has two kinds: a kind of is that the supply current of electrolyzer is reduced to zero, by artificial closed or disconnection short circuit mouth, cries the zero current operation; Another kind be with the supply current of electrolyzer reduce to primary current 1/2 or 1/3 after, be used splitter by artificial closed or break off the short circuit mouth, cry and fall current practice.More than two kinds of methods all have following shortcoming: 1, the closure or the opening operation time of general short-circuit block are 15～30 minutes; Operating period is connected on electrolyzer in the circuit all at no current or fall current status work; Can cause the fluctuation of groove condition behind the electric current recovery electricity; Frequent like this fluctuation of current and with groove in the fluctuation of temperature can greatly influence life-span of cell lining, shortening liner life cycle, even cause the electrolyzer generation bakie accident in the whole series loop; 2, in general the current consumption of electrolyzer is very large, the power load in the suitable medium-sized city of electrolyzer power consumption in series loop sometimes, big load like this, have a power failure continually and switch on very unfavorable to the steady running of electrical network; Also can have a strong impact on the rectifier unit life-span into electrolyzer with electricity; The cost that the energy waste of the cell lining life consumption that causes owing to above reason, the fluctuation of groove condition and rectifier unit life consumption have directly influenced Aluminum Electrolysis Production.
