電力參數校驗儀器

NAGP工頻信號發生器

NAGP frequency signal generator

產品別名

NAGP工頻信號發生器，工頻信號測試儀，工頻發生器，工頻信號發生器，南澳電氣公司工頻信號測試儀

一、概述

 本儀器采用單片機波形合成發生器產生高精度，低失真的正弦波電壓，可用于校驗頻率繼電器，同步繼電器等，也可作為低頻變頻電源使用。

 本儀器具有讀數直觀，精確，性能穩定，操作方便等特點。關鍵器件采用進口元件，是一種有著較高性能價格比的試驗儀器。

二、基本原理

 工頻信號發生器，主要由數字波形發生部分、功率放大部分、以及中央控制單元等組成。通過前面板控制數字波形發生單元產生一個頻率及幅度非常穩定的數字合成的正弦波，然后送到功率放大器進行放大。最后經過輸出切換及短路保護后輸出。中央控制單元則負責測量輸出頻率及輸出幅度，并監視整個系統的工作狀態是否正常。

三、技術指標

NAGP frequency signal generator

Also called name

NAGP power frequency signal generator, power frequency signal tester, power frequency generator, power frequency signal generator, Nanao Electric Company power frequency signal tester

One. Overview

This instrument uses single-chip waveform synthesis generator produces high-precision, low distortion sine wave voltage, can be used to calibrate frequency relays, synchronous relays, etc., can also be used as low-frequency inverter power supply.

This instrument has a reading intuitive, accurate, stable performance, easy to operate and so on. Key components of the use of imported components, is a high performance and low cost of the test equipment.

Two. Basic principles

NAGP Frequency signal generator, mainly consists of digital waveform generation part, power amplifier part, and the central control unit and so on. Through the front panel control digital waveform generation unit produces a very stable frequency and amplitude of the digital synthesis of sine wave, and then sent to the power amplifier for amplification. Finally, after the output switching and short circuit protection output. The central control unit is responsible for measuring the output frequency and output amplitude, and monitor the work of the entire system state is normal.
