Abstract
The utility model relates to a power-off protective device applied in an aluminum alloy casting process. The power-off protective device is characterized by comprising a 4kW/380V three-phase AC (alternating current) motor, a turbine decelerator, a 3kW/24V DC (direct current) motor, a 24-volt DC clutch, a 24V/90AH DC storage battery, a 380-volt three-phase AC contactor and a 24-volt DC contactor. The components are connected through power lines. The power-off protective device has black-out and power-off protective effects during an aluminum alloy hot top same-level closely-packed casting process and prevents safety accidents from happening.
Description
Technical field
The utility model relates to the power-off protection apparatus in a kind of aluminum alloy melt casting process.
Background technology
In aluminium type processing industry, in the same level solid matter casting process of aluminum alloy heat top, in case grid power blackout occurs, will inevitably cause that the traction on heat top pauses, cause high temperature aluminum water excessive, cause security incident.Therefore, special power-off protection apparatus of very necessary design is to avoid the generation of security incident.
The utility model content
The purpose of this utility model is to provide a kind of and plays power failure, power-off protection function in the same level solid matter casting process of aluminum alloy heat top, avoids the power-off protection apparatus in the aluminum alloy melt casting process that security incident occurs.
The technical solution of the utility model is achieved in that
Power-off protection apparatus in a kind of aluminum alloy melt casting process; its characteristics are that this power-off protection apparatus comprises the three phase alternating current motor of a 4KW/380V, a reducer of turbodrill, a 3KW/24V direct current machine, a 24V direct current clutch, the direct-flow storage battery of a 24V/90AH, a 380V three-phase ac contactor and a 24V D.C. contactor, and each parts is connected by electric wire.
The utility model is owing to adopted foregoing technical scheme, when making it be applied on the aluminium alloy casting device, can play such technique effect: when electrical network is normal, A.C. contactor energising adhesive, the alternating current machine work of 4KW, the direct current clutch is in clutch state, and alternating current machine drives the eddy current decelerator traction casting pallet casting aluminium bar that slowly descends, and this time, direct current machine was not worked; In a single day when the outage of power failure or fault occuring when, the A.C. contactor main contacts disconnects, and its auxiliary contact are closed, connects the D.C. contactor coil, D.C. contactor is closed, direct current clutch and direct current machine simultaneously electric work, continue to drive the work of eddy current decelerator, continue casting traction work, thereby obtain continual traction, avoid causing because of outage the pause of traction, cause high temperature aluminum water excessive, avoided the generation of security incident.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is circuit theory schematic diagram of the present utility model.
Embodiment
As shown in Figure 1; power-off protection apparatus in a kind of aluminum alloy melt casting process described in the utility model; it is characterized in that: this power-off protection apparatus comprises the three phase alternating current motor 1 of a 4KW/380V, a reducer of turbodrill, a 3KW/24V direct current machine 2, a 24V direct current clutch 3, the direct-flow storage battery 4 of a 24V/90AH, a 380V three-phase ac contactor and a 24V D.C. contactor, and each parts is connected by electric wire.
When electrical network is normal, A.C. contactor energising adhesive, the alternating current machine work of 4KW, the direct current clutch is in clutch state, and alternating current machine drives the eddy current decelerator traction casting pallet casting aluminium bar that slowly descends, and this time, direct current machine was not worked; In a single day when the outage of power failure or fault occuring when, the A.C. contactor main contacts disconnects, and its auxiliary contact are closed, connects the D.C. contactor coil, D.C. contactor is closed, direct current clutch and direct current machine simultaneously electric work, continue to drive the work of eddy current decelerator, continue casting traction work, thereby obtain continual traction, avoid causing because of outage the pause of traction, cause high temperature aluminum water excessive, avoided the generation of security incident.
