Accompanying drawing explanation
Fig. 1 is the schematic diagram of oil-field oil pumper comprehensive distribution box.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
With reference to Fig. 1, a kind of oil-field oil pumper comprehensive distribution box, described distribution box includes ICU, idle fixed compensation module and idle adjustable compensation module, described idle fixed compensation module and idle adjustable compensation module are all by the connection of fling-cut switch Yu oil-field oil pumper, and the control end of described fling-cut switch is connected with described ICU.
Further, described fling-cut switch includes reactive-load compensation chopper and the dynamic fling-cut switch of mechanical type, one end of the dynamic fling-cut switch of described mechanical type is connected with described idle adjustable compensation module, the other end of the dynamic fling-cut switch of described mechanical type, idle fixed compensation module all one end with described reactive-load compensation chopper are connected, the other end of described reactive-load compensation chopper and the connection of oil-field oil pumper.
Further, described distribution box also includes that motor protecter, described motor protecter are connected in the circuit of oil-field oil pumper, and described motor protecter is connected with described ICU.
Further, described distribution box also includes that electric quantity detection sensor, described electric quantity detection sensor are arranged on the circuit of oil-field oil pumper, and described electric quantity detection sensor is connected with described ICU.
Described ICU also includes remote transmission module.
The reactive-load compensation process of the present embodiment is as follows: the load curve of different pumping unit of well is different, and pumping unit load is a kind of relevant with underground working and balance, is cycle continually varying load cycling according to oil pumper stroke.Pumping unit load is change load cycling the most continuously.Change frequency is commonly used stroke and is represented, in general oil pumper stroke is 6～12 beats/min, i.e. period of change is 5～10 seconds.Two strokes up and down of period of change are respectively arranged with a dead point, when oil pumper is restarted after stopping, always load bigger dead point from two dead points and start to start.It is therefore desirable to motor of oil extractor should have bigger starting torque.When pumping unit load feature determines to select motor, it is necessary to match motor by peak torque.Time in reality in view of exceptions such as sand card, wax deposition, reason starting difficulty does not burns motor, and the most also very important person is for increasing motor allowance, and this aggravates " low load with strong power " phenomenon undoubtedly so that motor runs the most at low load.
Motor of oil extractor is when normally working, change according to oil pumper mechanical load, motor may have two kinds of diverse duties: when motor run mechanical load runs, and motor is in electric motor operation state, and now motor absorbs meritorious and reactive power from electrical network；When mechanical load drive motor runs, motor is in generator operation state, and now motor is from electrical network absorbing reactive power, sends active power to electrical network.And but no matter electric motor operation is in that state, and will be from electrical network absorbing reactive power.When motor is in generating state, from electric machine theory, the most unloaded reactive power of reactive power that motor absorbs from electrical network, its size is directly related with the method for designing of motor, material selection and manufacturing process etc..And motor is when being in electric motor state, reactive power change is then relevant with motor load size, and on-the-spot actual measured results shows: the load variations of the upper and lower stroke of oil pumper, can cause 1～4kvar idle change.
The motor of oil extractor overwhelming majority of oil field 1140V uses 6kV directly to join power supply, transformator-motor unit mode of connection, at active energy and the capacity of idle power of step down side stoichiometric consumption, it is the optimal compensation scheme that this system implements dispersion reactive-load compensation on the spot in motor terminal.It is fixed compensation to adding capacitor at Motor Control case, it is possible to obtain preferable compensation effect, power factor can be made to reach more than 0.85.
Preferably, reactive-load compensation capacitor is divided into two groups, fixed compensation and the adjustable compensation of about 3 or 4 kilovars.The zero load that fixed compensation capacitor device undertakes motor is idle, adjustable part is controlled by voltage regulator, with pumping unit load change regulation, compensating fluctuation is idle, and variation reactive-load compensation is controlled reactor by voltage regulator and realizes, and in-situ power factor can be improved to 0.98～1.00 after compensation.
Definite-purpose motor protector is increased for dragging motor and was used for stream, short circuit and open-phase protection, fault spread during to prevent from breaking down.
On the basis of no-power compensation function, GPRS remote communicating function is increased at ICU, to load real time data, the electric parameter such as voltage, electric current, active power, reactive power, power factor, harmonic wave and motor operating state, ambient temperature, other auxiliary switch signals are uploaded to main website of administration section.It is easy to administration section and grasps equipment operation condition and data acquisition in real time, thus realize unmanned.
