The oil pumper of most of petroleum crude oil producing well of past directly with alternating current machine as prime mover, pass through belt transmission, cam mechanism is converted into rotatablely moving of motor the upper and lower reciprocating of sucker rod, and the control of alternating current machine only is a switch, this control mode has following shortcoming, directly causes the huge waste of electric energy.
(1), the motor across-the-line starting, starting current is big;
(2), phase shortage and overload can't protect, and often causes motor to burn out, and can't monitor whether phase-deficient operation of motor, when the electrical network phase shortage, motor burnt out;
(3), power factor is very low, " falling to generate electricity " phenomenon that occurs in long-term underload and the motor operation course makes the power factor of oil pumper pace up and down in 0.2～0.3 such level, and clearly stipulate in the electric industry method of the new promulgation of China: the power factor of electrical appliance must reach more than 0.85, otherwise will be in 120% fine, this is concerning the oil district of the electrification energy, the power factor that improves oil pumper is extremely urgent, is the problem of standing in the breach and solve " falling to generate electricity " problem.
The utility model content:
The purpose of this utility model provides a kind of oil pump energy-saving device with regard to being the weak point that exists at prior art, it can make under system's situation that " generating " takes place each time and make response, the cut-out oil pumper is connected with electrical network, reaches purpose of energy saving.
For achieving the above object, the utility model comprises automatic switching module, bypass contactor, external interface module and peripheral operation system; Wherein, the automatic switching module is connected between 380V bus and the pumping-unit motor, be provided with thuristor throw-in and throw-off module, parameters of electric power detection module in it and judge control switching module, bypass contactor is in parallel with the automatic switching module, and external interface module links to each other with automatic switching module, bypass contactor and peripheral operation system respectively.
Also be connected with the overload protection thermal relay between described automatic switching module and the pumping-unit motor.
Be provided with auxiliary relay pack module, running status indicating module, voltage-stabilizing protection module, operation knob interface module in the described external interface module; wherein; the auxiliary relay pack module links to each other with bypass contactor by holding wire; the running status indicating module links to each other with indicator light on the peripheral operation system control panel via holding wire, and the operation knob interface module then links to each other with operation knob on the peripheral operation system control panel via holding wire.
Described auxiliary relay pack module also links to each other with buzzer siren via holding wire.
After adopting technique scheme, the beneficial effects of the utility model are: it detect to gather the parameters of electric power such as using electricity system load factor, electric current and voltage, power factor of oil pumper by sensing device, judge working state of system by calculating, " falling to generate electricity " of detecting each work period exactly is to take place, and dynamically control the operating state of switching module, make and to make response under system's situation that " fall generating " takes place each time, the cut-out oil pumper is connected with electrical network, thereby reach the purpose of economize on electricity, remarkable in economical benefits.In addition, but in the automatic switching module thuristor throw-in and throw-off module also have and use function stable, long reduced-voltage starting of life-span.
