Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of monitoring system of power equipment.
Background technology
At present, the preventative maintenance of power equipment is normally regular, so also can find many insulation defects, avoids the generation of operation power fault, thereby guarantees that power equipment normally moves.But along with the high capacity of electricity substation system high pressure power equipment and the variation of device structure, and the safe reliability requirement more and more higher to electric system, make this traditional repair method seem more and more incompatible.
Mainly show the following aspects
Need when (1) testing to have a power failure.
(2) test period long, test period is concentrated, and expends great amount of manpower and material resources.
(3) validity of test method, sensitivity are relatively poor.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of wireless insulated on-line monitoring system under the power equipment normal running (operation) conditions.
The scheme of the utility model technical solution problem is to adopt voltage transformer (VT), current transformer, signal processor (SignalPro), the AD collector, secondary microprocessor, secondary wireless communication module, main wireless communication module, master microprocessor and industrial computer constitute wireless insulated on-line monitoring system, the voltage transformer (VT) summation current transformer connect respectively the in-phase end of signal processor+and end of oppisite phase-, the OUT of signal processor connects the input end IN of AD collector, the OUT port of AD collector and the corresponding connection of the DB port of secondary microprocessor, the IN end of the OUT auxiliary connection wireless communication module of secondary microprocessor, secondary wireless communication module and main wireless communication module are complementary, the I/O of main wireless communication module is connected with the I/O of master microprocessor, and master microprocessor is connected with industrial computer by RS485 RS 232 twisted-pair feeder.Voltage transformer (VT) is installed on the bus of electricity substation system high pressure power equipment, current transformer is installed in the ground connection end screen of high voltage electric power equip ment.The monitoring personnel send by industrial computer and measure, orders such as dormancy, order is changeed the RS485 form with the RS232 form and is sent to master microprocessor, communicated by letter with secondary wireless communication module by main wireless communication module by the master microprocessor processing, pass through secondary microprocessor again, the AD collector, signal processor is passed on to the voltage transformer (VT) summation current transformer, the voltage transformer (VT) summation current transformer is controlled the AD collector to the collection of waveform by secondary microprocessor after receiving measuring command, the waveform of gathering is through after the secondary microprocessor rough handling, desired data passes back to the industrial computer of machine room through wireless communication module, data can form or picture show, check for the monitoring personnel.
The utility model can be to the charged insulating monitoring in real time that carries out of power equipment, the Leakage Current of the busbar voltage that real-time storage is measured, relevant power equipment and the dielectric loss tan δ of power equipment etc. record the data of various on-line monitorings by SQL Server database system management.Administration interface realizes that man-machine unification is mutual, shows functions such as monitoring result, the inquiry of historical data derivation, can also set test interval, the Measuring Time of system simultaneously etc.Raw data according to data-base recording can be to carrying out the presence diagnosis of equipment.
