Abstract
The utility model relates to a dryer motor current alarm device. A motor is connected with a current transformer which is connected with a PLC control system. In comparison with the prior art, the utility model has beneficial effects as follows: the dryer motor current alarm device has characteristics of low cost and simple structure, can be used to effectively reduce consumption of spare parts and avoid motor burning and funnel blocking accidents as well as material waiting and halting accidents caused by the above accidents, plays a role in protecting the motor and simultaneously has a good security effect on stable operation of a production system.
Description
Technical field
The utility model relates to a kind of warning device, particularly a kind of drying machine current of electric warning device.
Background technology
The equipment that is used for Concentrate Drying in the production process of pelletizing operation area is drum drier; by 2 YKR355-4 types; rated voltage 6KV high-voltage motor drives; be connected by 12 blob of viscoses between every motor and reductor; because daily operating load is large; thereby blob of viscose is fragile, and need to change 2-3 time average every month, and motor separated with reductor when blob of viscose damaged; the drying machine rear motor that stops still runs well; PLC control system None-identified, chain control does not have effect, causes the last process belt to remain in operation; finally cause leak stopping; in addition, after one-sided motor blob of viscose damages, opposite side motor independent operating; load is increased; easily occur to burn the motor accident, after motor burnt out, it was long to change the motor activity duration; cause easily stopping accident to be expected, the stable smooth operation of producing is exerted an influence.
Therefore, a kind of drying machine current of electric warning device has solved existing technical problem, has played the protective effect to motor, avoids occurring burning motor, the sub-accident of leak stopping.
Summary of the invention
The purpose of this utility model is to provide a kind of warning device of current of electric, and the stable smooth operation of production system is played good guaranteeing role.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of drying machine current of electric warning device, described motor is connected with current transformer, and current transformer is connected with the PLC control system.
Compared with prior art, the beneficial effects of the utility model are:
A kind of drying machine current of electric warning device; have cost characteristics low, simple in structure; effectively reduce the consumption of standby redundancy; motor, the sub-accident of leak stopping have been avoided occurring burning; and the stopping accident to be expected that causes thus; play the protective effect to motor, simultaneously the stable smooth operation of production system played good guaranteeing role.
Description of drawings
Fig. 1 is electric current principle figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further specified:
As shown in Figure 1, a kind of drying machine current of electric of the utility model warning device, described motor is connected with current transformer, and current transformer is connected with the PLC control system.
When using the utility model; obtain motor current signal by current transformer; transfer to the PLC control system; by the program intercepts current signal; be increased to set point such as current of electric, then the PLC control system is sent alarm signal and is automatically stopped the drying machine operation, has played the protective effect to motor; avoid occurring burning motor, the sub-accident of leak stopping, and the stopping accident to be expected that causes thus.
Above described only be basic principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
