Real-time-line Wide Range Power Meter Is Developed

Along with the super-speed development of the electric power industry, extensive and applied development in electric power has been abnormality quickly, electric power resources is becoming too increasingly missing .Under such big background,people are increasingly consider electric power of valid and reasonable with transparently applied to be important, the current electric power measurable instrument is constantly improvement, the function becomes stronger, more dependable, the usage becomes more convenient, the measurment distance becomes wider ,the higher precise instruments replaced the instrument in existence. The direction of replacing concentrated primarily in aspects such as :the quality of dependablity, advancement, useage , extendance , openning .According to this kind of circumstance, we combined with actual circumstance, and developed this item through cooperating with zhengzhoutaike company in Zhengzhou, aiming at developing a kind of instrument that can be measure electric power and powerless,and visual power, current valid value, voltage valid value, charged barbed wire net frequency, phase data on-line to examine three phases three lines, three phases four lines eletric net data quickly .To realize the purpose of rapid,designed the wide-range current measurement to apply all aspect.and realize the copy and receive of wired or cordless data, also can pass the key on the form proceeds to set and inquire, in addition, install an USB interface, which can passes the machine procedure, proceeding the fast intelligence adjust and receive data. This design can also compare the errors with the data of other electric power on-line timingly and analyse, get an error margin percentage, manifest the related data, combine to have password protection function.This paper is to studies primarily the work that contents do have: undergone the data of past every kind of electric power gauge, designed the techenology parameter based on taike corporate's requirement and practice circumvent .checked the instrument for index , developed all circuit module and total designing, improved the designing through the test ,at last caused the products.The designing adopt the method that passage intelligent cut over, realize the breadth...
