Description
Technical field
The present invention relates to a kind of on-line measuring device, particularly a kind of RTU automatic on-line pick-up unit that is used for digital transformer substation.
Background technology
In recent years, along with the continuous development of electric detecting technology, intelligent measuring equipment constantly is applied in the electrical measurement technology in the digital transformer substation.RTU is exactly the typical substitute of this series products, and widespread usage is energy-conservation, the most promising modern times monitoring product of the most effective, tool power, optimization of intelligent monitoring in the monitoring system of digital transformer substation.It also is the indispensable front-end equipment of information network platform simultaneously, and its application identity the beginning of most advanced and sophisticated electric quantity test technology of the new period.But the RTU that is applied in digital transformer substation has also brought a new difficult problem to us, and that is exactly that " cycle, magnitude tracing Sheng waitd upon Suan
Because RTU is that electronic module assembly and sensing element are formed, it is used in again in the environment such as specific electric field interference, humiture influence, dust invasion and attack.Therefore, irregular distortion can take place along with prolonging working time in the measurement characteristics of RTU, in case " distortion " exceeds the limit value that dispatches from the factory, can cause the serious deviation of operational monitoring data, thereby cause the intelligent monitoring system mistake to send out " safety early warning signal " or " trip signal ", cause the unplanned power outage of operation power safety when serious.
So, in the RTU on-line operation,, all must examine surely the performance period no matter whether condition is arranged to its periodic check.But in a single day RTU is applied to produce and just is difficult to withdraw from from running status, if it is arranged periodic calibration, be to plan the implementation cycle calibrating of electric supply installation unit ability out of service, can influence the management and running normal management like this, and the time delays of the application reply that has a power failure also can influence RTU be subjected to overhaul period validity.
Summary of the invention
The technical problem to be solved in the present invention is, but the inspection of a kind of remote monitoring school is provided, and makes things convenient for the RTU periodic verification, and the charge value that can the uninterrupted power supply system when calibrating continues to monitor, to substitute the shortcomings and deficiencies that the existing technology of mode calibrating manually exists.
The present invention takes following technical scheme: a kind of RTU automatic on-line pick-up unit, it comprises the following part that overlaps
Replace and use RTU, be connected on the conversion equipment of equipment operation loop, the interim replacement when being used for online RTU detection is for the normal operation and the monitoring of power supply unit provides safeguard;

Test center's concentrator station, link by channel transfer equipment and equipment operation loop conversion equipment, high stability standard source and three-phase standard scale, in be provided with the PC or the portable computer of RTU remote detecting system, also be provided with test terminal and database server, be used for online PTC periodic calibration and control.
Used high stability standard source is adopted detection system for closing the robotization friendship eventually.
Used three-phase standard scale is adopted detection system for closing the robotization friendship eventually.
Channel transfer equipment comprises netting twine, switch, router, fire wall and server.
Each equipment operation loop conversion equipment control two-way RTU device, the one tunnel is RTU to be checked, another road is replacement RTU, and is provided with secondary circuit input, output wiring terminal, remote signalling terminal and remote control terminal on each equipment operation loop conversion equipment.
The preservation that act as test result of database server, and generate detection raw readings, test certificate, test result L. A., cycle management form or examined early warning report.
Equipment operation loop conversion equipment is to online RTU or replace the switching that comprises communication signal with the switching of RTU
Compared with the prior art, the present invention will replace with equipment such as RTU, equipment operation loop conversion equipment, high stability standard source, three-phase standard scale, channel transfer equipment and test center's concentrator stations and overlap, set up one and close intelligent long-range RTU device detection system eventually, the process of its remote detection is:
1) by program control switch the RTU of online (or stop using) is cut (comprising that communication signal switches) from secondary line, and be linked on the RTU proving installation;
2) " replenishing RTU " that the RTU operation work that is cut open is set by the RTU device replaced (comprising that communication signal inserts);
3) according to the testing scheme of " predefine ", RTU automatically and RTU device standard enter test mode, then the comparison output quantity of RTU and RTU device standard by the RTU device the communications protocol oral instructions be passed to the test terminal of inspection center;
4) calculating, analysis and the data storage of test data finished in the test terminal, and forms test report and test result.
Utilize this cover system, can be when RTU week inspection, remote testing is controlled, and interrupts the operation of normal power supply unit in test, simultaneously, in testing process, allows replacement put in the circuit with RTU and moves, and has guaranteed the continuity of power supply unit data monitoring.In addition; this system also sets up the self-protection function; detect each flow process of link can both automatic diagnosis hardware effort state error rate; if find irreversible working routine obstacle or unusual; just can recover tested RTU work virgin state automatically; isolate RTU automatic on-line pick-up unit, automatically terminate calibrating procedure, and start the alert mode reporting system and control personnel and fix a breakdown.
