Abstract
The present invention relates to a kind of multiple groups electric parameters transducers uniformly to test application of the law technology in transmitter calibrating.The prior art is mostly that single electric parameters transducer is independently examined and determine, and every transmitter need to disconnect secondary line again, and engineering is big, even and if for the electric parameters transducer assay approval of same purposes, it cannot guarantee that error is consistent, there is also deviation when practical on-load, pole is unfavorable for operations staff's monitoring.Present invention composition includes: transmitter calibrating installation (1), the input terminal of the transmitter calibrating installation is connected with the magnitude of current input terminal of one group of transmitter (2) by power supply line, the output end of the transmitter calibrating installation is in parallel by power supply line with the voltage output end of one group of transmitter, output restores after the completion of verification, whole voltages, the magnitude of current are inputted, are attached using all analog quantitys of the external experiment power supply line to all same type transmitters.The present invention uniformly tests application of the law technology in transmitter calibrating for multiple groups electric parameters transducer.
Description
Technical field:
The present invention relates to a kind of multiple groups electric parameters transducers uniformly to test application of the law technology in transmitter calibrating.
Background technique:
According to maintenance for generation companies standard and electric parameters transducer calibrating regulation, requires and whole inspections periodically are carried out to electric parameters transducer
It is fixed, to ensure the accuracy of each electrical data, electric parameters transducer at least over one hundred in power plant, quantity is more and also purposes not
One, the multiple transmitters having show same test point, and this requires multiple transmitter errors to want almost the same.Therefore generating set
It is huge to the calibrating project amount of electric parameters transducer during maintenance, it needs to put into very big human resources；
The prior art is mostly that single electric parameters transducer is independently examined and determine, and every transmitter need to disconnect secondary line, engineering again
Greatly, even and if for the electric parameters transducer assay approval of same purposes, cannot guarantee that error is consistent, when practical on-load also deposits
In deviation, pole is unfavorable for operations staff's monitoring.
Summary of the invention:
The object of the present invention is to provide a kind of multiple groups electric parameters transducers uniformly to test application of the law technology in transmitter calibrating.
Above-mentioned purpose is realized by following technical scheme:
A kind of multiple groups electric parameters transducer uniformly tests application of the law technology in transmitter calibrating, and composition includes: transmitter inspection
Device is determined, it is characterized in that: the magnitude of current input terminal of the input terminal of the transmitter calibrating installation and one group of transmitter passes through electricity
The voltage output end of the series connection of source line, the output end of the transmitter calibrating installation and one group of transmitter passes through power supply line simultaneously
Connection, output restores after the completion of verification, inputs whole voltages, the magnitude of current, is become using external experiment power supply line to all same types
All analog quantitys of device are sent to be attached；
Specific testing procedure are as follows:
(1) classified to electric parameters transducer according to the analog signals accessed, same group of voltage will be used, the magnitude of current
Comprising voltage transmitter, current transducer, frequency transmitter, zero sequence transmitter, negative phase-sequence transmitter, the institute including power transducer
There is transmitter to be detected to unify wiring；
(2) test parameters is inputted item by item, is treated the calibrating each check post of transmitter and is examined and determine；(3) gauging error is met the requirements,
It is qualified to calculate test result；It is unqualified to calculate test result, calibration
Transmitter, unqualified after calculating test result, transmitter cancels, the transmitter more renewed；
(4) finally unify dosage monitoring record and compare DCS system, AVC system, PMU system,
The display numerical value of DEH system each region, logarithm is checked, is compared, it is ensured that data are accurate, error substantially close to.
The utility model has the advantages that
1. the present invention, which is mainly to provide a kind of multiple groups electric parameters transducer, uniformly tests application of the law technology in transmitter calibrating, should
The technical issues of method solves is using " multiple groups electric parameters transducer unifies method of testing " technology for improving working efficiency, it is ensured that is become
There is larger effect in terms of sending device elementary error, not only saves human resources investment, moreover it is possible to guarantee multiple groups electric parameters transducer error one
It causes, the amount of working at the same time is few, improves work efficiency, and has largely established again to worker safety, equipment safety solid
Basis.
The present invention is attached using all analog quantitys of the external experiment power supply line to all same type transmitters, wherein electricity
Flow is concatenated, and voltage is carried out and connect, which has largely saved human resources, and project amount is reduced, quasi-
True property is higher.
The technology that the present invention uses can also be extended in the calibrating of all kinds of same type equipment, such as comprehensive protector,
Meter etc. only needs to use experiment power supply line relatively more, but saves a large amount of repetitive operations.
The present invention saves the wiring work when verification of big transmitter, not only saves the hair that the time also effectively prevent mis-wired
It is raw, it is ensured that the safety of work；It solves the inconsistent caused each region of transmitter error and shows offset issue, be conducive to run
Personnel correctly judge primary equipment operating status, and dosage detection is disposable to be completed, and save the extensive work time, dosage test itself
Be also an innovative point, according to regulation regulation verification finish, pass the test can, in order to ensure final effect, the application
It increases a dosage detection project more, proposes unified test, it is ensured that the accuracy of transmitter verification result.
