Description

The adaptive power conservation threephase asynchronous

Technical field: the utility model relates to a kind of motor, is specifically related to a kind of threephase asynchronous of used for oil-field oil pumper.

Background technology: motor is that maximum power equipments is used in the oil field, and the power consumption of motor of oil extractor accounts for more than 1/3rd of the total power consumption in oil field, because the torque of oil-field oil pumper demand when starting is bigger, and the torque of demand is much smaller during operate as normal, so existing motor of oil extractor in order to satisfy the needs of detent torque, is all installed than the big a lot of high power motor of operate as normal power demand; And oil pumper often all is the continuous operation of a couple of days even tens of days, and therefore, there is the problem of power dissipation in motor of oil extractor under normal operation, thereby has caused that the motor of oil extractor power factor is low, efficient is low, the problem of power wastage; This is " low load with strong power " phenomenon that is difficult to change.

The utility model content: the present utility model a kind of adaptive power conservation threephase asynchronous, it has the function of the power output of automatic adjusting motor of oil extractor, different power demand when starting and during normal operation to adapt to, power of electric motor factor and whole efficient have been improved, save electric energy in a large number, reduced cost for oil production.The utility model has comprised motor field frame 1, End cover for motor 2, motor rotary shaft 3, terminal box 4, it has also comprised high-power rotor coil 5, high-power stator coil 6, small-power rotor coil 7, small-power stator coil 8, adaptive controller 9, adaptive controller 9 is installed in the terminal box 4, motor field frame 1 is by left shell 1-1, right shell body 1-2 forms, high-power stator coil 6 is fixed on the inside of left shell 1-1, high-power rotor coil 5 correspondences are fixedly mounted on the motor rotary shaft 3 of high-power stator coil 6 inside, small-power stator coil 8 is fixed on the inside of right shell body 1-2, and small-power rotor coil 7 correspondences are fixedly mounted on the motor rotary shaft 3 of small-power stator coil 8 inside.Operation principle: the utility model is made up of two separate motor windings, the public motor output revolving shaft of two motors, separately stator coil and rotor coil are arranged, they both can be worked simultaneously, also can work independently, can be competent at different work requirements, oil-field oil pumper is when starting, can open two motors works simultaneously, can export bigger power, and when normally moving owing to only need less power output, so can allow high power motor or small power motor isolated operation, adaptive controller 9 is judged desired power by the electric current of monitoring power input, the operation of control two motors and stopping.The utlity model has the function of the power output of automatic adjusting motor of oil extractor, the demand of different capacity when starting and when running well to adapt to, improved power of electric motor factor and whole efficient, improved the overall efficiency of the electric power utilization of oil pumper operation, energy-saving effect is remarkable; Solved " low load with strong power " phenomenon to a great extent, made that oil-field oil pumper motor operational efficiency improves, consume reduces.
