Background technique
At home in current aluminium electrolysis cell control unit controlling of production process, there was only software to the control protection of anode lifting
With hardware encryption, control loop can only be disconnected, the disadvantage is that:
Slot control machine AC380V main power source three-phase small air breaker rated current 40A has the protection such as short circuit, overcurrent.
But does not have long-range excitation tripping function, such as contactor adhesion failure occur, but due to not being fault current, only anode is mentioned
The running current of lifting motor, slot control machine AC380V main power source three-phase small air breaker can not be to contactor adhesion etc.
Failure is protected, and cannot achieve fault trip.
When there is multiple contacts of contactor adhesion fault simultaneously, when reaching the contactor adhesion signal protection time, control
Circuit board in house software protection processed (15S) in a specified time can disconnect circuit board inner control loop, but anode lifting
Motor main circuit is because of the adhesion simultaneously of multiple contacts of contactor, although contactor control loop power supply disconnects, contactor major loop
(primary circuit) contact is still switched on, and anode lifting motor still has power supply, then can continue to keep anode liter or anode drop.
During slot control machine headstock manual operation button is overhauled or operated, worker operates or checking experiment
When, such as occur that anode rises or drop button blocks or situations such as knob contact adhesion, anode is risen or drop control instruction triggers always, then
Slot control machine control circuit board software program can't detect failure, work still according to normal procedure, and anode can continue always
It rises or drops, to cause the generation of electrode separation of electrolytic bath or pier bottom accident.
The purpose of this utility model can avoid anode lifting during slot control machine operation aiming at disadvantage mentioned above completely
It is uncontrolled and caused by from pole or the pernicious major accident of pier bottom.
Utility model content
The purpose of this utility model is to provide a kind of anti-aluminium electrolysis cell control unit anode runaway protectors, on solving
State the problem of proposing in background technique.
To achieve the above object, the utility model provides the following technical solutions: a kind of anti-aluminium electrolysis cell control unit anode mistake
Control protective device, including main power source control loop, control electric power loop, delay monitoring control loop and slot control machine control circuit board
Electric power loop, it is characterised in that: power supply shunt release KA is fixed at main power source air-break circuit-breaker QS tripping mechanism, and is connected
Three phase mains, main contactor KM1 and main contactor KM2 by concatenation reach anode and rise contactor KM3 or anode drop contactor
KM4, and connect anode lifting motor M.
Preferably, the power supply shunt release KA is fixed on the right side of main power source air-break circuit-breaker QS at tripping mechanism, slot
Control machine control circuit board electric power loop is de- by 380V/220V power transformer T access, time relay KT and with power supply shunt opening
Button device KA is incorporated to the control loop.
Preferably, anode lifting motor major loop rises contactor KM3 or anode drop contactor KM4 by anode and connects with master
Tentaculum KM1, main contactor KM2 concatenation.
Compared with prior art, the utility model has the beneficial effects that
1. the utility model has high-precision, automatically, self application is real-time continuous to be monitored and the advantages that self diagnosis；
2. the utility model anode lifting can be avoided completely uncontrolled during slot control machine is run and caused by from pole or
The pernicious major accident of pier bottom.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the technical solution in the utility model, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of anti-aluminium electrolysis cell control unit anode guarantor out of control
Protection unit, including main power source control loop, control electric power loop, delay monitoring control loop and slot control machine control circuit board power supply
Circuit, power supply shunt release KA 1 is fixed at 2 tripping mechanism of main power source air-break circuit-breaker QS, and connects three phase mains, warp
The main contactor KM1 3 and main contactor KM2 4 of concatenation are crossed, anode is reached and rises contactor KM3 5 or anode drop contactor KM4
6, and anode lifting motor M 7 is connected, and realize anode lifting, the time is incorporated in anode lifting Motor Control circuit
Delay monitoring of the relay KT 8 as movement, once anode lifting exceeds the predetermined time, time relay KT 8 is acted immediately
On the one hand slot control machine control circuit board electric power loop is interrupted, main power source air is on the other hand made by power supply shunt release KA 1
The tripping tripping of circuit breaker Q S 2.
Further, power supply shunt release KA 1 is fixed at 2 right side tripping mechanism of main power source air-break circuit-breaker QS,
Slot control machine control circuit board electric power loop is accessed by 380V/220V power transformer T 9, time relay KT 8 and and power supply
Shunt release KA 1 is incorporated to the control loop.
Further, anode lifting motor major loop rises contactor KM3 5 or anode drop contactor KM4 6 by anode
4 are concatenated with main contactor KM1 3, main contactor KM2, realize anode lifting.
Anode rises contactor KM3 5 and to act, main contactor KM1, KM2 simultaneously operation, in this way ability adhesive action, makes sun
Pole elevating motor carries out anode lifting.Equally, anode drop contactor KM4 6 will be acted, and main contactor KM1, KM2 are moved simultaneously
Make, ability adhesive action makes anode lifting motor carry out anode decline.
8 delay time of time relay KT is adjustable, can require to be adjusted according to aluminium cell operating condition or technological operation
Whole, the normally-closed contact of time relay KT 8 is concatenated into slot control machine control circuit board electric power loop.
The utility model relates to the contents of transformation: on the basis of slot control machine original control system, having newly established power supply is
