Abstract
The invention discloses an air knife fan AVR voltage-stabilizing apparatus applied to a BOPP production line. The air knife fan AVR voltage-stabilizing apparatus comprises a Hall sensor, an electric reactor, a driving transmitter and a circuit breaker, wherein the Hall sensor is connected with the driving transmitter in parallel and then is connected with the electric reactor in series; the electric reactor is connected with a motor for the fan; the other end of the driving transmitter is connected with the circuit breaker; the Hall sensor is used for detecting voltage and current fluctuations; and the voltage and current fluctuation amplitude detected by the Hall sensor is 20%. According to the air knife fan AVR voltage-stabilizing apparatus, a condition of shutdown caused by faults is prevented when the voltage fluctuation amplitude exceeds 20%; and therefore, it is ensured that the equipment still can run stably under voltage fluctuations.
Description
Technical field
The present invention relates to a kind of air sword blower fan AVR stable-pressure device for high wide cut, high speed biaxial tension BOPP production line.
Background technology
Current domestic BOPP old production line; die head fluid and slab sharp cooling roll attaching method; the pressurization of commonly used frequency conversion high pressure positive blower realizes laminating; and this process section is extremely important; stability and the sustainable requests of convection cell attaching air quantity are significantly high, in production process, when device external electrical network mains ripple is frequent; slab defect can be caused to shut down, and impact produces.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of air sword blower fan AVR stable-pressure device being applied to BOPP production line, when BOPP external factory power supply grid fluctuates, and burning voltage, meet complicated technology and the application of many variable working condition.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
It is applied to the air sword blower fan AVR stable-pressure device of BOPP production line, including Hall element, reactor, driving converter and chopper, then Hall element connects with reactor with driving converter parallel connection, the motor of reactor connecting fan, drives the other end of converter to connect chopper.
Preferably, two drive converter only one of which work when voltage is normal.
Further, the fluctuation of Hall element detection voltage and current.
Preferably, the fluctuating margin of the voltage and current of Hall element detection is 20%.
Further, the condition of Hall element transmission signal is: the fluctuating margin of voltage and current is more than 20%, and overtime continues 500ms.
Beneficial effects of the present invention:
1, when voltage pulsation is more than 20%, will not break down stop jumping again.Can join equipment voltage occur fluctuation time, still stable operation.
2, when voltage declines, the power factor of run with load is effectively improved, and improves power grid quality.
3, the AVR air knife voltage-stabilizing system of redundancy, improves the equipment rate of attendance, effectively reduces the stop jumping because voltage pulsation causes.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Embodiments of the present invention is described in detail below.
As shown in Figure 1, a kind of air sword blower fan AVR stable-pressure device being applied to BOPP production line of disclosure, including Hall element 1, Hall element 22, reactor 3, drive converter 1, driving converter 25 and chopper 7, Hall element 1 is connected with driving converter 1, Hall element 22 is connected with driving converter 25, Hall element 1 is in parallel with Hall element 22, then connect with reactor 3, the motor 4 of reactor 3 connecting fan, is connected chopper 7 after driving converter 1 and driving converter 1 parallel connection.
Operationally, drive converter 1 and drive converter 1 only one of which work when voltage is normal, Hall element 1 and Hall element 22 detect the fluctuation of voltage and current, and the fluctuating margin of the voltage and current of Hall element 1 and Hall element 22 detection is 20%.
When unusual fluctuations and drop occur when outside three phase supply, and the fluctuating margin of voltage and current is more than 20%, and overtime continues 500ms, and Hall element one detects device and transmits signal, converter two is driven to work, it is ensured that air sword blower fan is working properly stable.
The effective guarantee of the present invention stability of system, the application of this AVR redundant actuation system, it is simultaneously achieved cover system when operationally breaking down suddenly, another set of system can quickly respond protection switching and put into operation, and the conversion time is very short reaches Millisecond.
Invention described above embodiment, is not intended that limiting the scope of the present invention.Any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within the claims of the present invention.
