  Abstract:This article introduces the application of the Hall Sensor used in chile. Hall current sensors are mainly used to isolate and convert AC, DC, pulse and other complex signals. After signal control of current signals are converted according to the Hall Effect Theory, they can be directly acquired by AD, DSP, PLC, secondary instruments and other devices. Hall current sensors are widely applicable for acquisition and feedback in the current monitoring, battery application, inverter, solar power management, direct current cabinet, DC motor drive, electroplating, welding, frequency converter, UPS servo control systems. They feature the quick response, wide range of measurement, high precision, strong overload capacity, good linearity and excellent anti-interference performance.

  與傳統(tǒng)直流(liú)電(diàn)流計量一般采用(yòng)分流器或互感器測(cè)量(liáng)方法相比，開口(kǒu)式(shì)霍爾(ěr)傳(chuán)感器具(jù)有以下優點(diǎn)：

  1）原(yuán)邊副(fù)邊絕緣(yuán)強度高，可達AC 12kV隔(gé)離；

  2）無(wú)插入(rù)損(sǔn)耗；

  3）動(dòng)態性(xìng)能(néng)好(hǎo)：響應時間小於(yú)20us速(sù)度di/dt高於20A/us

  4) 安裝(zhuāng)時無需拆卸原(yuán)邊電纜或(huò)母(mǔ)排，特別適(shì)用於不允許斷電設(shè)備的改(gǎi)造(zào)施(shī)工。

  Compared with the traditional DC current measurement method generally adopted by shunt or transformer, the open-type Hall sensor has the following advantages:

  1) High insulation strength of primary side and secondary side, up to AC 12KV isolation;

  2) No insertion loss;

  3) Good dynamic performance: the response time is less than 20uS and the tracking speed Di /dt is higher than 20A/ uS

  4) There is no need to disassemble the original side cable or bus during installation. It is especially suitable for the transformation and construction of equipment that is not allowed to lose power.
