Abstract
The utility model discloses a converter is alarm system in advance, including warning circuit, the electric bell that the multiunit connected in parallel each other, multiunit warning circuit establishes ties with the drive electric bell, and every warning circuit of group is including establish ties to together temperature switch, converter pilot lamp, relay coil, relay normally open switch in order, and it has resistance to connect in parallel in the both ends of converter pilot lamp. The utility model adopts the above technical scheme technological effect below having: the temperature that can effectively prevent the fin of converter continue to rise, effectively guarantees equipment normal operating, can effectively improve production efficiency and product quality, can provide the reference for converter manufacturer, through converter software and parameter setting to and the IO terminal accomplishes this function, make the circuit simple more with facilitate the use.
Description
Technical field
The utility model is related to technical field of textile machine, more particularly to a kind of forecast of textile machinery frequency converter
Alarm system.
Background technology
The application of frequency converter is popularized very much, and when frequency converter works, the heat that the power output module of frequency converter is produced leads to
Fin absorption is crossed, by the cooling fan forced heat radiation on fin, it is ensured that frequency converter reliability service.But it is cold when frequency converter
But after fan is damaged or fin causes serious dirty stifled because of the environmental factor for using, fin radiates bad, the temperature of fin
Can raise, reach certain value（80 degrees Celsius of fin surface of actual measurement）When, frequency converter warning heatsink temperature is too high and stopping is transported
OK, the normal operation of production equipment is directly affected.
When my company Domestic New GA308 warp sizing machines run, there are 7 frequency converters to run simultaneously, the too high report of frequency converter temperature
Alert rate of breakdown is highest, and each failure stops platform, causes slurry and cotton yarn loss, and direct economic loss is average 500 yuan, weight
It is new to drive to need to prepare for more than 2 hours, affect production efficiency and product quality.
The content of the invention
The technical problems to be solved in the utility model is for problem above, there is provided a kind of effectively to prevent dissipating for frequency converter
The temperature of backing continues to raise, and equipment is effectively ensured and normally runs, can effectively improve production efficiency and
The frequency converter pre-alarm system of product quality.
To solve above-mentioned technical problem, the utility model is employed the following technical solutions, frequency converter pre-alarm system, including many
Group warning circuit, electric bell parallel with one another, multigroup warning circuit is connected with electric bell is driven, and is included per group alarm circuit in sequential series
To temperature switch together, frequency converter indicator lamp, relay coil, relay normally open switch, the two ends of frequency converter indicator lamp are simultaneously
It is associated with resistance.
The utility model has following technique effect using above-mentioned technical proposal：The fin of frequency converter can effectively be prevented
Temperature continues to raise, and equipment is effectively ensured and normally runs, and can effectively improve production efficiency and product quality, can manufacture for frequency converter
Business provides reference, and by frequency converter software and parameter setting, and I/O terminals the function is completed, and makes circuit simpler and square
Just use.
It is described further to originally new with reference to the accompanying drawings and examples.
Description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
In figure：1- temperature switches, 2- frequency converter indicator lamps, 3- relay coils, 4- relay normally opens switch, 5- electric bells；
6- warning circuits.
Specific embodiment
Embodiment, as shown in figure 1, frequency converter pre-alarm system, including multigroup warning circuit 6 parallel with one another, electric bell 5,
Multigroup warning circuit 6 is connected with electric bell 5 is driven, and is included per group alarm circuit 6 in sequential series to temperature switch 1, frequency conversion together
Device indicator lamp 2, relay coil 3, relay normally open switch 4, the two ends of frequency converter indicator lamp 2 are parallel with resistance.
During work, the fin cooling fan of frequency converter is damaged or serious dirty stifled, and fin temperature rise is also not reaching to report to the police
Temperature value, pre-alarm temperature sensor in temperature switch 1（It is set as 60 degrees Celsius）Sense fin temperature rise, temperature switch 1
Closure, makes warning circuit 6 work, and corresponding relay coil 3 is powered, while corresponding frequency converter indicator lamp 2 is lighted, relay
Normal open switch 4 is closed, and electric bell 5 works, and maintenance technician is informed rapidly, takes technical measures, prevent the temperature of fin after
Height of continuing rising, is effectively ensured equipment and normally runs, it is to avoid because the failure causes the loss in production.
