Embodiment
Below in conjunction with the accompanying drawings, the invention will be further described.
In order to realize that the real-time monitoring to high-tension switch gear hydraulic mechanism energy storage state is set there is provided a kind of high-voltage switch gear
The monitor controller of standby energy storage state, the device can be arranged on inside or the other positions of high-tension switch gear.It is led
To include oil pressure sensor, central processing unit and wireless communication module.When the fuel injection pressure signal that oil pressure sensor is gathered exceeds setting
Warning value when, central processing unit according to the fuel injection pressure signal of collection carry out failure reason analysis, and pass through wireless communication module will
Fuel injection pressure signal and fault message, which are sent, is transferred to receiving terminal.
In order to improve the function of above-mentioned monitor controller, as shown in figure 1, the monitoring control of high-tension switch gear energy storage state
Device processed can be specifically included：Battery-powered circuit, filtering conditioning circuit module, A/D modular converters, dormancy awakening triggering electricity
Road, central processing unit, serial communication modular, auxiliary switch, optocoupler, 4G communication modules, data memory module, time setting circuit mould
Block, relay drive circuit and energy storage motor.The analog signal of oil pressure sensor, torque sensor and voltage sensor is through filtering
Ripple conditioning circuit module and A/D modular converters are changed into data signal.Central processing unit reads the corresponding data signal of each sensor,
Add after time tag and handled and analyzed, then deposit in data memory module.In order to reduce the electricity of hole coupling
Magnetic disturbance, is improved the reliability of device, is powered using battery feed circuit to device.It can be made using dormancy awakening triggers circuit
Central processing unit enters low power consumpting state in the case of oil pressure changing value is smaller, saves electric energy；Monitoring that oil pressure changing value is super
When crossing setting value, dormancy awakening triggers circuit makes central processing unit be rapidly switched to normal operating conditions.Before installation, pass through serial ports
COM1 sets running parameter, and these parameters are used to set the work in every parameter of device, main to include sampling
Frequency, activation threshold value and related setting value etc.；And corresponding SIM card is installed, (it can certainly be correspondingly arranged into for 4G communications
Other radio communications)., can be by receiving terminal to the corresponding operation code of device transmission in normal course of operation, inquiry is current
With history energy storage state and fault message.
Monitoring and control method corresponding to above-mentioned monitor controller is：1) oil of high-tension switch gear hydraulic mechanism is gathered
Signal is pressed, and the fuel injection pressure signal collected and the warning value of setting are compared；2) set when the fuel injection pressure signal collected exceeds
During fixed warning value, judge whether act in the switch of setting time inner high voltage before；If 3) high-voltage switch gear is not acted, judge
Revealed for oil circuit.
If high-voltage switch gear is acted, continue to judge, in addition it is also necessary to which the criterion of judgement includes following at least one：A, height is pressed off
Close whether operating frequency is more than setting value；Whether the energy storage motor working time is less than setting minimum value after b, operation；C, energy storage electricity
Whether electromechanical source voltage signal is less than minimum operating voltage；Whether d, energy storage motor output torque is zero；When the criterion is
When no, then it is determined as that oil circuit is revealed.For example：When it is only any one in a, b, c, d that sentencing of also needing to judge is acute, if this
It is no that kind, which sentences play, then is determined as that oil circuit is revealed；When sentencing of also needing to judge it is acute as any two kinds in a, b, c, d when, only when
Both sentence play when being no, can just be determined as that oil circuit is revealed；Sentence acute as any three kinds in a, b, c, d when also need to judge
When, only when it is no that these three, which sentence play, it can just be determined as that oil circuit is revealed；When sentencing of also needing to judge it is acute as a, b, c, d this
At four kinds, only when it is no that these four, which sentence play, it can just be determined as that oil circuit is revealed, as shown in Fig. 2 wherein, what criterion judged
It is sequentially adjustable.
If above-mentioned criterion a judged result, which is high-voltage switch gear operating frequency, is more than setting value, illustrate to cause oil pressure value to surpass
The reason for going out warning value is that high-voltage switch gear operation is excessively frequent.If above-mentioned criterion b judged result is energy storage motor work after operation
Make the time less than setting minimum value, then the reason for explanation causes oil pressure value to exceed warning value is that energy storage time is too short.If above-mentioned sentence
It is less than minimum operating voltage according to c judged result for energy storage motor power supply voltage signal, then explanation causes oil pressure value beyond warning
The reason for value is that energy storage motor supply voltage is too low.If it is zero that above-mentioned criterion d judged result, which is energy storage motor output torque,
Illustrate that energy storage motor is damaged.Related oil pressure information and fault message to receiving terminal can be sent by wireless network,
So as to maintenance personal's pointedly handling failure.In monitoring process, criterion, criterion can also be increased in addition according to actual conditions
More, result of determination is more accurate.
In addition, it is necessary to which the oil pressure collected is believed before the fuel injection pressure signal collected is compared with the warning value set
Number analog quantity is converted to digital quantity signal, so that central processing unit can carry out the analyzing and processing of data message.In order to ensure to turn
The accuracy of rear data signal is changed, filtering conditioning step can be added before data signal is converted into.Equally, for the ease of right
The processing and analysis of Monitoring Data, are stored, analyzed or are sent out after can adding time tag in the data signal after conversion
Send.
In the normal course of operation of device, due to high-voltage switch gear operation or certain reason be less than the oil pressure in accumulator
(P during initiation value<P starts), device control energy storage motor starts, and oil pump starts to suppress, to accumulator energy storage；When what is monitored
When oil pressure reaches rated pressure, device controlled motor stops, and oil pump stops suppressing.Set and interrupt in embedded software, work as oil
When pump continues suppressed time more than setting value, it may be possible to there occurs the contactor that accumulator leakage or control energy storage motor are suppressed
The failures such as failure, can so cause certain damage to hydraulic mechanism, and interrupt response, control energy storage motor shuts down, gone forward side by side
Row time-out alarm.Idiographic flow is as shown in Figure 3.
By monitoring high-voltage switch gear hydraulic mechanism energy storage state in real time, comprehensive many reference amounts characteristic can interpolate that failure
Reason, the reliability service and maintenance to power system is significant.The relevant information and failure obtained after monitoring is handled
Information is transmitted by wireless network, reduces communication line, has saved the input cost of optical cable and cable.By relevant information
It is sent directly to receiving terminal, it is to avoid the bankroll problem that extra setting intermediate equipment is brought.
