三、結(jié)構(gòu)簡介(Construction)
1、JLENJH8-220W數(shù)字式光電組合互感器是一種新型的電子式組合互感器。它不同于傳統(tǒng)的電磁式電流、電壓互感器,它采用了光電
隔離、數(shù)據(jù)數(shù)字化、光通信技術(shù)。還用高度可靠的電氣絕緣設(shè)計使可靠性大大加強。
JLENJH8-220W digital photoelectric combination transformer is a new type of electronic combined transformer. It is
different from the traditional electromagnetic current transformer and voltage transformer. It adopts the optoelectronic isolation, data digitization and technology of optical communication. The design of highly reliable electric insulation makes the reliability improved significantly.
2、它也不同于基于法拉第磁光效應(yīng)和克爾電光效應(yīng)的光電組合互感器,它的電壓信號采用電容分壓原理,電流信號傳感器就是低能
量電流互感器和羅可夫斯基線圈。電流信號在高電位處就轉(zhuǎn)變?yōu)閿?shù)字信號,通過光纖傳到低電位處。所以測量的準(zhǔn)確度高,抗振動性、抗外界溫度變化、抗電磁干擾及運行壽命都有保障。
It is also different from the photoelectric combination transformer that is based on Faraday magneto-optical effect
and Kerr electro-optic effect. Its voltage signal adopts the principle of capacitance voltage division and the sensor for current signal is the low-energy current mutual inductor and the Rogowski coil. The current signal is transferred to digital signal at the high potential and the digital signal is transferred to the low potential through optical fiber. Therefore, the accuracy of measurement is high. It has the characteristics of shock resistant, resistance of temperature of external environment, anti-electromagnetic interference and the service life is guaranteed.
3、本裝置中,高電位處的供電是一個重要的技術(shù)創(chuàng)新。本裝置采用了低電位激光供能和高電位取能等多重供能技術(shù),產(chǎn)品運行可靠
性高。
The power supply at the high potential of this device is a technical innovation. This device adopts multiple
technology of power supply such as laser power supply at the low potential and energy output at high potential.

Therefore, the product operates stably.
4、JLENJH8-220W數(shù)字式光電組合互感器的絕緣柱采用硅橡膠外護(hù)套傘裙,為支柱式。結(jié)構(gòu)輕便、簡單,重量輕;有良好的抗污能力
、可靠性高。
The insulating column of JLENJH8-66W digital photoelectric combination transformer
adopts the silastic outer sheath and umbrella skirt. It is the pillar type, which enable simple and light structure
and light weight. It has the ability to counter pollution and high reliability.
