Problems solved by technology
There are many precautions during calibration. If you are not very professional, you will often increase the possibility of misoperation, which will directly affect the accuracy and reliability of the monitoring data of the unit.
Therefore, at present, general users entrust the calibration of TSI meters to electric power research institutes in various provinces, which is inconvenient for disassembly and transportation, delays time, affects the progress of the project, and costs a lot of money

The invention provides an intelligent calibrator and calibrating method for a monitoring and protecting instrument of a steam turbine. Among them, the calibrator includes a computer, a signal generator and a data I / O module for two-way connection, the output of the steam turbine monitoring and protection instrument monitor is connected to the input of the data I / O module, and the output of the signal generator and the data I / O module The terminal is connected to the input terminal of the signal conditioner, and the output terminal of the signal conditioner is connected to the input terminal of the steam turbine monitoring protection instrument monitor to be verified. Calibration method Directly input the type and range of the monitor required to be calibrated on the computer interface, and the software will automatically calculate the signal that should be output according to the type, installation method, installation angle, and sensitivity of the sensor, and then instruct the calibration instrument to output Specified signal, all alarm set points can be verified, the analog output of the monitor can be recorded and error analysis can be performed. The invention has the advantages of lowering the threshold of professional knowledge involved in the engineering and technical personnel engaged in maintenance, and more effectively allowing users to directly perform correct calibration on the spot.
Description
technical field [0001] The invention relates to an intelligent calibrator and a calibrating system for a steam turbine monitoring and protection instrument, which is used for continuously calibrating the online monitoring instrument for the running state of a steam turbine generator set, and belongs to the steam turbine monitoring and protection instrument calibrator and calibrating method technology field. Background technique [0002] The routines for calibrating steam turbine monitoring and protection instruments (hereinafter referred to as TSI) are as follows: [0003] 1) Calibration of axial displacement and differential expansion: [0004] Such as figure 1 As shown, it is a schematic diagram of the calibration of the axial displacement and differential expansion monitor. The calibration principle is: calculate the magnitude of the corresponding DC signal according to the sensitivity of the sensor used in the axial displacement and differential expansion monitor, man...
