Abstract

The embodiment of the invention discloses a multi-functional digital partial discharge detector calibrator. The multi-functional digital partial discharge detector calibrator comprises a memory for caching output signals, a numerical control pulse signal generation module for generating controllable pulse signals, a power frequency synchronous triggering module for generating amplitude-controllable power frequency synchronous signals, a digital-to-analogue conversion unit for converting digital data to an analog wave form, an amplitude control unit for controlling the pulse signals and the power frequency synchronous signal amplitude, a control interface, a pulse output port and a power frequency synchronous port, wherein the control interface, the pulse output port and the power frequency synchronous port are arranged in an external hooking mode. The multi-functional digital partial discharge detector calibrator is various in functions and can replace a plurality of detectors to finish the calibration of the partial discharge detector, a digital mode is adopted to arrange various parameters of the pulse signals, the signal output is accurate, test experiments of multiple parameters of the partial discharge detector can be completed through a user interface, and the multi-functional digital partial discharge detector calibrator is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of calibration and calibration of instruments, in particular to a multifunctional digital partial discharge instrument calibrator. Background technique [0002] The partial discharge meter is used to measure the apparent discharge of electrical equipment when partial discharge occurs, and is a key device to ensure the safe operation of the power grid. In order to ensure the accuracy and reliability of the measurement data of the partial discharge instrument, it is necessary to use a calibrator to calibrate the signal measured by the partial discharge instrument. [0003] However, the partial discharge instrument calibrator in the prior art has the following disadvantages: the function is single, and it can only realize the control of pulse polarity and charge amount, and the test of other parameters of the partial discharge instrument requires the help of other instruments, which makes the test process cumbe...
