摘要：近年來(lái),由于電力電子器件的發(fā)展,變頻調(diào)速、逆變、斬波等新技術(shù)的應(yīng)用,電壓、電流的波形已不再是標(biāo)準(zhǔn)的正弦波或直流。傳統(tǒng)的互感器顯然已不適于對(duì)該波形的測(cè)量。因此,很多國(guó)家都相繼進(jìn)行了非接觸式電流電壓傳感器的研究開(kāi)發(fā),其中尤以霍爾電流電壓傳感器被視為該項(xiàng)技術(shù)的代表。

Abstract: In recent years, due to the development of power electronic devices and the application of new technologies such as frequency converter, inverter and chopper, the waveform of voltage and current is no longer the standard sine wave or DC. The traditional CT is obviously not suitable for the measurement of the waveform. Therefore, many countries have carried out the research and development of non-contact current and voltage sensor, especially Hall current and voltage sensor is regarded as the representative of this technology.

0. 項(xiàng)目概述： Project Overview

沙特AFAQY公司主做通訊設(shè)備安裝項(xiàng)目，該客戶購(gòu)買(mǎi)我司霍爾電流傳感器主要安裝在UPS電源柜中，以監(jiān)測(cè)電流情況，保護(hù)后端設(shè)備.

Saudi Arabia AFAQY company mainly do the installation project of communication equipment. The Hall current sensor they purchased  is mainly installed in the UPS power cabinet to monitor the current situation and protect the back-end equipment.

霍爾傳感器，適用于交流、直流、脈沖等復(fù)雜信號(hào)的隔離轉(zhuǎn)換，通過(guò)霍爾效應(yīng)原理使變換后的信號(hào)能夠直接被AD 、DSP、PLC、二次儀表等各種采集裝置直接采集和接受，體積小，壽命長(zhǎng)，安裝方便，響應(yīng)時(shí)間快，電流測(cè)量范圍寬精度高，過(guò)載能力強(qiáng)，線性好，抗干擾能力強(qiáng)等優(yōu)點(diǎn)。

Hall sensor is suitable for the isolation and conversion of complex signals such as AC, DC and pulse. Through the Hall effect principle, the converted signal can be directly collected and accepted by various acquisition devices such as ad, DSP, PLC and secondary instrument. It has the advantages of small volume, long service life, convenient installation, fast response time, wide current measurement range, high precision, strong overload capacity and good linearity, It has the advantages of strong anti-interference ability.

4、總結(jié)Summmary

在UPS電源系統(tǒng)中，閉環(huán)霍爾電流傳感器用于測(cè)量輸出電流，UPS控制器根據(jù)此電流進(jìn)行反饋控制，保證逆變電源正常工作。由于其響應(yīng)速度快，特別適用于計(jì)算機(jī)中的不間斷電源。

In the UPS power system, the closed-loop Hall current sensor is used to measure the output current, and the ups controller carries out feedback control according to the current to ensure the normal operation of the inverter. Because of its fast response speed, it is especially suitable for uninterruptible power supply in computer.
