The Integration Of Beam Pumping Unit Energy-saving Design Drag

Oil pumping unit in accordance with the work of the current situation and analysis on the system configuration, I would like to develop a unit that meets the requirements of heavy-duty starter, but also allows the transformer, electric motor running in the economic load area, with a transfer function of capacity distribution transformers.The capacity of the transformer unit with the load changes, which can automatically adjust the capacity of the capacity of the transformer. Transfer capacity transformers and other transformers, it is through the relationship between electromagnetic induction, or the role of the use of mutual inductance from one circuit to another circuit of a static transmission of electrical power, according to Power Loss Characteristics of oil to reduce the transformer capacity, only need to meet the pumping oil machine start-up performance requirements, both to improve the load factor transformers.Through the low-voltage side of distribution transformer winding structure to change so that it can be two types of output voltage 400V and 660V, single-chip computer control system timing control, so that voltage is within the scope of a certain period of time in the work of 660V, in other time frame in a 380V work to increase the technical difficulty of Electric Larceny. Operating voltage of 660V will also achieve the purpose of reducing loss.As a result of these intelligent control system, through four, respectively, AC contactor control transformer 380V, 660V smoke joints with three-phase AC induction motor round corner of the stars, makes the single-chip digital signal output control, auto-transformer in two alternating operation between the output voltage, motor also access to stars and corner of the conversion, to tie in with the change of output voltage transformer, and alternating cycle can be adjusted through the single-chip, so as to achieve the purpose of preventing the theft of electricity.
