Specific embodiment
With reference to the accompanying drawing, the invention will be further described.
In order to realize the real-time monitoring to high-tension switch gear hydraulic mechanism energy storage state, provides a kind of high-voltage switch gear and set
Inside or other positions in high-tension switch gear can be set in the monitor controller of standby energy storage state, the device.It is led
It to include oil pressure sensor, central processing unit and wireless communication module.When the fuel injection pressure signal of oil pressure sensor acquisition is beyond setting
Warning value when, central processing unit according to the fuel injection pressure signal of acquisition carry out failure reason analysis, and by wireless communication module will
Fuel injection pressure signal and fault message transmission are transferred to reception 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 specifically include: battery-powered circuit, filtering conditioning circuit module, A/D conversion module, dormancy awakening triggering electricity
Road, central processing unit, serial communication modular, auxiliary switch, optocoupler, 4G communication module, 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
Wave conditioning circuit module and A/D conversion module become digital signal.Central processing unit reads the corresponding digital signal of each sensor,
It is added after time tag and is handled and analyzed, then deposit in data memory module.In order to reduce the electricity of cable coupling
Magnetic disturbance improves the reliability of device, is powered using battery feed circuit to device.It can be made using dormancy awakening trigger circuit
Central processing unit enters low power consumpting state in the smaller situation of oil pressure changing value, saves electric energy；Monitoring that oil pressure changing value is super
When crossing setting value, dormancy awakening trigger circuit makes central processing unit be rapidly switched to normal operating conditions.Before installation, pass through serial ports
Communication port sets running parameter, and for these parameters for setting to the work in every parameter of device, main includes 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 communication
Other wireless communications).In normal course of operation, corresponding operation code can be sent to device by receiving terminal, inquiry is current
With history energy storage state and fault message.
Monitoring and control method corresponding to above-mentioned monitor controller are as follows: 1) acquire the oil of high-tension switch gear hydraulic mechanism
Signal is pressed, and collected fuel injection pressure signal is compared with the warning value of setting；2) it is set when collected fuel injection pressure signal exceeds
When fixed warning value, judge whether high-voltage switch gear acts in setting time before；If 3) high-voltage switch gear does not act, determine
For oil circuit leakage.
If high-voltage switch gear acts, continue to judge, it is also necessary to which the criterion of judgement includes following at least one: a, and height presses off
Close whether operating frequency is greater than the set value；B, whether the energy storage motor working time is less than setting minimum value after operation；C, energy storage electricity
Whether electromechanical source voltage signal is lower than minimum operating voltage；Whether d, energy storage motor output torque are zero；When the criterion is
When no, then it is determined as that oil circuit is revealed.Such as: when any one sentenced in acute only a, b, c, d for also needing to judge, if this
Kind sentence play be it is no, then be determined as oil circuit leakage；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；When also need to judge sentences play as any three kinds in a, b, c, d
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 Figure 2, wherein criterion judgement
It is sequentially adjustable.
If the judging result of above-mentioned criterion a is that high-voltage switch gear operating frequency is greater than the set value, illustrate to cause oil pressure value super
It is that high-voltage switch gear operation is excessively frequent the reason of warning value out.If the judging result of above-mentioned criterion b is energy storage motor work after operation
Make the time less than setting minimum value, then illustrates that the reason of causing oil pressure value to exceed warning value is that energy storage time is too short.If above-mentioned sentence
Judging result according to c is that energy storage motor power supply voltage signal is lower than minimum operating voltage, then explanation causes oil pressure value beyond warning
The reason of value is that energy storage motor supply voltage is too low.If it is zero that the judging result of above-mentioned criterion d, which is energy storage motor output torque,
Illustrate that energy storage motor is damaged.Related oil pressure information and fault message can be sent to terminal is received by wireless network,
So as to maintenance personal's pointedly handling failure.In monitoring process, criterion, criterion can also in addition be increased according to the actual situation
It is more, determine that result is more accurate.
In addition, needing to believe collected oil pressure before by collected fuel injection pressure signal compared with the warning value of setting
Number analog quantity is converted to digital quantity signal, so that central processing unit is able to carry out the analysis processing of data information.In order to guarantee to turn
The accuracy of rear digital signal is changed, filtering conditioning step can be added before being converted into digital signal.Equally, for the ease of right
The processing and analysis of monitoring data are stored, analyzed or are sent out after time tag being added in the digital signal after conversion
It send.
In the normal course of operation of device, since high-voltage switch gear operates or is lower than the oil pressure in accumulator due to certain
When initiation value (P < P starting), device controls energy storage motor starting, and oil pump starts to suppress, to accumulator energy storage；When what is monitored
When oil pressure reaches rated pressure, device, which controls motor, to be stopped, and oil pump stopping is suppressed.It is arranged in embedded software and interrupts, works as oil
When pumping lasting suppressed time more than setting value, it may be possible to accumulator leakage have occurred or control the contactor that energy storage motor is suppressed
The failures such as failure, can cause certain damage, interrupt response to hydraulic mechanism in this way, and control energy storage motor shuts down, goes forward side by side
Row time-out alarm.Detailed process is as shown in Figure 3.
By real-time monitoring high-voltage switch gear hydraulic mechanism energy storage state, comprehensive many reference amounts characteristic can judge failure
Reason is of great significance to the reliability service and maintenance of electric system.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 receive terminal, avoids bankroll problem brought by additional setting intermediate equipment.
