Description
Technical field
The utility model relates to a kind of control device. Specifically, be the intelligent frequency-conversion control device for Long-distance Control oil field oil-immersed pump working condition.
Background technology
All know in oil exploitation industry, due to submersible electric pump have simple to operate, the scope of operation is little, oil pump capacity is large, oil recovery efficiency advantages of higher, has been widely used at present the oil exploitation in domestic and international oil field. Because submersible electric pump is operated in the shaft bottom of 1000 ~ 3000 meters of below grounds, working environment is severe (high temperature, deep-etching etc.) very. Traditional submersible electric pump is mostly total head, power frequency power supply mode, owing to adopting the power supply of total head, power frequency, can not far distance controlled, and to only have and just can know at the scene whether submersible electric pump normally works, control device falls behind, and production efficiency is low.
The 2nd, when total head, power frequency startup, can electrical network be produced and be impacted, make the dash current of motor large, impulsive torque is large, easily cause the damage of the accelerated ageing of motor and cable and electric pump blade, axle system. In oil recovery process, because liquid level often changes, need often electric pump to be carried out to start stop operation, rush of current frequently, the service life that can reduce equipment.
The 3rd, because oilfield electric net is in electrical network end, adopt total head, power frequency power supply mode can cause voltage often to play pendulum, submersible electric pump is easily damaged.
The 4th, owing to adopting total head, power frequency power supply, the power output of submersible electric pump is constant, is difficult to adjust according to the condition of production power output of submersible electric pump, and energy waste is serious.
Utility model content
Problem to be solved in the utility model is to provide a kind of submersible electric pump intelligent frequency-conversion control device. Adopt this intelligent frequency-conversion control device, not only can be at a distance to the duty of submersible electric pump control, realize control automation, enhance productivity, and submersible electric pump is not fragile, service life that can extend submersible electric pump, can also reduce the waste of the energy.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Submersible electric pump of the present utility model comprises submersible electric pump and frequency converter with intelligent frequency-conversion control device, and the input of frequency converter is connected with three phase mains by breaker, and the output of frequency converter is connected with submersible electric pump by cable. Be characterized in also comprising controller and antenna, controller is connected with antenna by cable. Described controller contains touch-screen and control end, and described control end is connected with frequency converter by wire. Between controller and three phase mains, there are transformer and Switching Power Supply, described three phase mains contains the first phase line, the second phase line and third phase line, the elementary two ends of transformer are connected with the second phase line with the first phase line of three phase mains respectively, the secondary two ends of transformer are connected with negative pole with the positive pole of Switching Power Supply respectively, are connected with successively heater and temperature controller between the positive pole of Switching Power Supply and negative pole.
Wherein, between the secondary respective ends of the positive pole of Switching Power Supply and transformer, be in series with successively the 4th fuse and the 3rd fuse; Between the elementary two ends of transformer and the first phase line of described three phase mains and the second phase line, be connected with respectively the first fuse and the second fuse; Between the first phase line, the second phase line and third phase line and the ground of three phase mains, be all connected to arrester.
As can be seen from the above scheme, because the utility model contains controller and antenna, controller is connected with antenna by cable. Described controller contains touch-screen and control end, and described control end is connected with frequency converter by wire. Between controller and three phase mains, there are transformer and Switching Power Supply, described three phase mains contains the first phase line L1, the second phase line L2 and third phase line L3, the elementary two ends of transformer are connected with the second phase line L2 with the first phase line L1 of three phase mains respectively, the secondary two ends of transformer are connected with negative pole N with the anodal L of Switching Power Supply respectively, between the anodal L of Switching Power Supply and negative pole N, are connected with successively heater and temperature controller. When work, accept or launch gps signal by antenna, thereby at a distance the duty of submersible electric pump being controlled, not needing scene just can know whether submersible electric pump normally works. Owing to adopting intelligent frequency-conversion control, can electrical network not produced and be impacted, can avoid the accelerated ageing of motor and cable and the situation of the damage that electric pump blade, axle are to occur. Even in oil recovery process, because liquid level often changes, needs often electric pump to be carried out to start stop operation, rush of current also can not reduce the service life of equipment frequently. Owing to adopting intelligent frequency-conversion control, voltage, all the time in stable state, makes submersible electric pump not fragile again. Owing to adopting intelligent frequency-conversion control, can adjust in real time according to the condition of production power output of submersible electric pump, thereby avoid the waste of the energy again.
