Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figures 1 to 7, a kind of intelligent buckling protective device of the present invention, including：Positioned at the in vivo power grid of cabinet
Flicker detection unit 1, program processing unit 2, text-processing unit 3, breaker 4, UPS5, Switching Power Supply 6 and relaying 7.
Wherein, power grid flickering detection unit 1 is abnormal for detecting power grid.
Program processing unit 2 is used for program control operations.
Program processing unit is using a kind of programmable memory, for its internally stored program, performs logical operation, suitable
The user oriented instructions such as sequence control, timing, counting and arithmetical operation, and it is each to pass through digital or analog pattern input/output control
The machinery or production process of type.
Text-processing unit 3 is used for man-machine interface, parameter setting, data query.
Text-processing unit also known as terminal display are a kind of human-computer interaction systems presented with word merely.Pass through text
This display by the content of required control, is written as corresponding program, is finally shown on the interface of text display
Come.In this way, not only substantially increasing the convenience of operation, and work efficiency can be significantly improved.
Breaker 4 is used to cut-off circuit.
Breaker（English name：Circuit-breaker, circuit breaker）It is to refer to close, carry and open
Electric current under normal loop condition of breaking can simultaneously close, carry before the deadline and cut-off the electric current under abnormal loop condition
Switching device.
UPS5 is used to provide stand-by power supply.
UPS（Uninterruptible Power System/Uninterruptible Power Supply）, i.e., not between
Power-off source is by accumulator（Mostly plumbic acid maintenance-free accumulator）It is connected with host, passes through the modular circuits such as host inverter
Direct current is converted into the system equipment of alternating current.It is mainly used for single computer, computer network system or other electric power electricity
Such as offers such as solenoid valve, pressure transmitter of sub- equipment are stable, continual supply of electric power.When alternating current input is normal, UPS will
Load is supplied to use after alternating current voltage stabilizing, UPS at this time is exactly an electric main voltage-stablizer, while it is also filled to self-contained battery
Electricity；Work as commercial power interruption（Forced outage）When, UPS by the direct current energy of battery, passes through the method for zero switch transition of inversion immediately
Continue to supply 220V alternating currents to load, load is made to maintain to work normally and protect load soft and hardware without damage.UPS equipment
Usually protection can be provided to overtension or brownout.
Switching Power Supply 6 is used to power to text-processing unit and relaying.
Relaying 7 is used to send on-off model to control device.
Intermediate relay (intermediate relay), also referred to as relays：For relay protection and automatic control system
In, to increase the quantity of contact and capacity.It is used to transfer M signal in control circuit.The structure of intermediate relay and
Principle is essentially identical with A.C. contactor, is with the main distinction of contactor：The main contact of contactor can by high current,
And the contact of intermediate relay can only pass through low current.So it is only used in control circuit.It is usually to be touched without main
Point, because overload capacity is smaller.So its is entirely auxiliary contact, quantity is relatively more.New national standard to centre after
The definition of electric appliance is K, and old-national's mark is KA.Usually DC power supply is powered.Minority uses Alternating Current Power Supply.
The voltage protection relay test voltage ripple of power network that intelligent buckling protective device passes through power grid flickering detection unit 1
With use equipment alarm export situation：When voltage fluctuation is more than preset value and equipment alarm has output, it is judged as that flickering stops
Machine；When voltage fluctuation be more than preset value but equipment alarm without output when, be judged as that flickering is not shut down；When voltage fluctuation is not less than pre-
If value but equipment alarm are judged as equipment failure itself when having output.
Further, when voltage fluctuation is more than preset value and equipment alarm has output, it is judged as that flickering is shut down, it is described
Intelligent buckling protective device starts subsequent action program, and homing device alarm starts restarting equipment program, equipment is made to open again
It is dynamic；As voltage fluctuation be more than preset value but equipment alarm without output when, be judged as that flickering is not shut down, the intelligence buckling protection dress
Automatic homing is put to detection state；It is judged as that equipment is originally die when voltage fluctuation has output not less than preset value but equipment alarm
Barrier, the intelligence buckling protective device output sound-light alarm, and indicate faulty equipment.
