Description
Technical field：
The present invention relates to electrolytic cell intelligence control system technical field, specifically a kind of electrolytic cell slot control machine anode lifting is protected
Protect device.
Background technology
Electrolytic Workshop, electrolytic cell intelligence slot control machine is operated in high temperature, the environment of highfield, electronic component aging
It hurry up, program entanglement or deadlock situation occur often, cause that anode electrolytic cell Infinite Auto amount rises or endless decline shows
As.Anode Infinite Auto amount, which rises, can cause anode to depart from electrolyte levels, and the increase of cell resistance moment puncture short mouthful occurs and drawn
Play serious explosion accident；Anode Infinite Auto amount, which declines, to cause anode to go straight down to bottom land, and electrolyte and aluminium water are squeezed
Go out, cause electrolytic cell equipment to damage when serious, it is impossible to repair.Both the above situation is as found not in time, any one occur, all
Serious economic loss can be brought to enterprise.
Current anode lifting protection is more to be protected by the way of limit switch is installed on anode bus, but such a guarantor
Shield mode lifts that protection domain is wide in range, and sensitivity is low, it is impossible to meet the electrolytic cell normally small accurate protection of voltage pulsation in production
Demand, protective effect is limited；Other limit switch is arranged on upper part of the electrolytic cell field position, is influenceed by high temperature, highfield, passes through
Often break down, cause protection device to fail, lose protective effect, potential safety hazard is big.
