Abstract
The utility model discloses a high-voltage soft-start system for joint control of a plurality of air compressors, which comprises a high-voltage incoming wire cabinet. The input end of the high-voltage incoming wire cabinet is connected with an external power grid, the output end of the high-voltage incoming wire cabinet is connected with a soft-start cabinet, a first motor cabinet and a second motor cabinet arranged in parallel, the output end of the soft-start cabinet is respectively connected with the output ends of the first motor cabinet and the second motor cabinet through a relay, and the output ends of the first motor cabinet and the second motor cabinet are electrically connected with a first air compressor and a second air compressor. The starting current of the high-voltage soft-start system can be controlled within twice of the rated current, the requirements of large-torque startup of the air compressors can be satisfied, the starting current can be greatly reduced, power can be saved, and the impact on the high-voltage power grid can be reduced.
Description
Technical field
The utility model relates to the high pressure soft start and joins control multiple air compressors system.
Background technique
The especially load of voltage levels of this kind equipment at present, producing very big " 5 ~ 7 times " electric current during because of starting all is very big impact to electrical network and load.Be protection equipment and electrical network, common way is to adopt auto-transformer, and voltage was to reach the purpose that reduces starting current when methods such as resistance or the starting of star triangle reduced starting.Shortcomings such as such way not only cost is high, and equipment volume is big, and power consumption height and starting torque are little.Be not suitable for very much especially especially for air compressor system.
The model utility content
The purpose of the utility model provides a kind of high pressure soft start and joins control multiple air compressors system; Starting current but can be controlled within 2 times of rated current; Solved the requirement of the big torque starting of air compressor, starting current is significantly reduced, not only saved electric energy but also reduced impact high-voltage fence.
The technological scheme of the utility model is following:
The high pressure soft start joins control multiple air compressors system; Include the high pressure incoming line cabinet; The input end of high pressure incoming line cabinet links to each other with extraneous electrical network; Output terminal is connected with soft start cabinet arranged side by side each other, the first motor cabinet, second motor cashier's office in a shop, and the output terminal of said soft start cabinet is connected to the output terminal of the first motor cabinet, the second motor cabinet respectively through relay, and the output terminal of the first motor cabinet, the second motor cabinet is electrically connected with first air compressor, the second air compressor terminal.
The output terminal of said soft start cabinet is connected to the output terminal of the first motor cabinet, the second motor cabinet respectively through relay (KM1), (KM2).
The VFS series that the utility model utilization controllable silicon converter technique is made has grade frequency conversion stepless voltage regulation soft starter device to introduce frequency conversion mechanism simultaneously based on ' jumping the ripple principle '; Can realize that motor is by " 0 rotating speed is to 1/4 rotating speed "; " 1/4 rotating speed is to 1/2 rotating speed ", 3 grades of Soft Start-up Process of " 1/2 rotating speed to full rotating speed ", starting torque will be the conventional motors reduced voltage starting ten surplus times; Starting current but can be controlled within 2 times of rated current; It has solved the requirement of the big torque starting of air compressor on the one hand, and starting current is significantly reduced, and has not only saved electric energy but also reduced the impact to high-voltage fence.Especially valuable is to use a VFS device to start multiple air compressors respectively.These characteristics prove absolutely that this system has the theory advanced person, practice thrift investment, cut down the consumption of energy the innovation setting of a tractor serves several purposes.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; The high pressure soft start joins control multiple air compressors system; Include high pressure incoming line cabinet 1; The input end of high pressure incoming line cabinet 1 links to each other with extraneous electrical network, and output terminal is connected with on soft start cabinet each other arranged side by side 2, the first motor cabinet 3, the second motor cabinet 4, and the output terminal of soft start cabinet is connected to the output terminal of the first motor cabinet, the second motor cabinet respectively through relay; The output terminal of the first motor cabinet, the second motor cabinet is electrically connected with first air compressor 5, second air compressor, 6 terminal, and the output terminal of soft start cabinet is connected to the output terminal of the first motor cabinet, the second motor cabinet respectively through relay K M1, relay K M2.
After 10,000 volts of high pressure get into this system by the high pressure incoming line cabinet; Arbitrary pneumatics unit can be earlier again after being provided with earlier on the soft starting cabinet " VFS cabinet " in 2 as if starting; Pressing starting button [like starting 1* machine] start-up sequence will carry out automatically; At first KM1 adhesive, it approximately is 12 at this moment that the while power supply frequency is adjusted to 1/4 frequency.Raising frequency is to 25HZ automatically again behind the 5HZ operation set time, and corresponding half the back in short-term frequency of reruning that reaches of rotating speed rises to both full-speed operations of full range.KM1 automatic disconnection in soft starting cabinet this moment " VFS cabinet ", 1DL adhesive in the 1* motor cabinet.Electric motor starting is accomplished.It is normal that soft starting cabinet recovers.Again can repeat reach process if will start 2* unit whole system this moment.As long as press corresponding stop button if will shut down, then corresponding D L switch breaks off, and the outage of pneumatics unit stops.Native system all is provided with the integrated protection appearance cashier's office in a shop to voltage at soft starting cabinet and motor, electric current, and frequency, parameters such as temperature all have supervision and warning and out-of-limit shutdown function.
Claims (2)
1. the high pressure soft start joins control multiple air compressors system; Include the high pressure incoming line cabinet; It is characterized in that: the input end of high pressure incoming line cabinet links to each other with extraneous electrical network; Output terminal is connected with soft start cabinet arranged side by side each other, the first motor cabinet, second motor cashier's office in a shop, and the output terminal of said soft start cabinet is connected to the output terminal of the first motor cabinet, the second motor cabinet respectively through relay, and the output terminal of the first motor cabinet, the second motor cabinet is electrically connected with first air compressor, the second air compressor terminal.
