Description
Technical field: the utility model relates to a kind of dynamo bearing Insulation Live Testing device.
Background technology: the energy that modern Chinese national economy construction and social development are utilized is electric energy substantially.The ten big emphasis energy-saving and emission-reduction engineerings that China starts, primary emphasis is exactly the energy-saving and emission-reduction of coal fired power generation industry, the most effective solution improves the single-phase capacity of generator, China brings up to 1100MW with single-machine capacity at present, the electric coal consumption of the every degree of medium and small unit is dropped to about 320 grams from about 535 grams, improved benefit, saved the energy, ecologic environment is improved.Raising along with the high-rating generator pool-size, require also more and more higher to the generator operating condition detection technique, particularly the detection of high-rating generator bearing insulation operating mode does not thoroughly solve for many years technically, and domestic many large-scale units the dynamo bearing damage accident take place in succession cause great economic loss.
Summary of the invention: the purpose of this utility model provides a kind of quick dynamo bearing Insulation Live Testing device that accurately detects data.The technical solution of the utility model is: a kind of dynamo bearing Insulation Live Testing device comprises: cabinet A, signal gathering unit A1, the central processing unit A3 that detects conditioning unit A2, industrial computer, a signal show and alarm unit A4, industrial indicator screen A5, signal is nursed one's health the central processing unit A3 that unit A2 sends into industrial computer after testing through signal gathering unit A1, sends instruction by the central processing unit A3 of industrial computer and delivers to signal and show and alarm unit A4, industrial indicator screen A5.
The utility model principle is to measure shaft current, active power, reactive power three road signals of bearing insulation, send among the central processing unit A3 of industrial computer through signal gathering unit A1 processing, computing machine is (being under active power and the reactive power) corresponding comparative analysis of normal data by preserving among the central processing unit A3 of special mathematical model to the leakage current signal of gathering the axle insulation and industrial computer under operating mode of the same race, if find that leakage current greater than setting value, provides " warning " so that take corresponding fault handling measure.
The utility model is applied to the detection of large synchronous generator bearing insulation operating mode, detect data processing, analysis, all finish by computing machine.Groove position that quick and accurate detection data are short-circuited and dynamo bearing adopt the standard code of insulating material to compare analysis, make the criterion whether the dynamo bearing insulation satisfies the technical requirement of generator.
Advantage of the present utility model: (1) actions menu is provided with complete.Be provided with " management " " measurement " " database " " setting " and menus such as " helps ".
(2) device application software is developed under ' WINDOWS ' environment, has good man-machine interface interface.
(3) if the dynamo bearing leakage current greater than setting value, pick-up unit printout automatically " figure reports to the police " and data file.
Whether (4) user can access the historical summary of dynamo bearing insulation operating mode at any time, need repairing generation according to effectively preventing generator shaft generation electrocorrosion fault is provided thereby can be generator amature.
(5) the device cabinet is a modular structure, is convenient to maintenance.
