摘要:
根据轨道交通牵引供电与直流测量需求，针对直流牵引系统电气参数频繁变化的特点，采用MCU（微控制单元）控制的PWM（脉冲宽度调制）方法，利用PCB（印刷电路板）内嵌磁耦合互感器技术，研发了适用于直流高电压检测的隔离变送器，能够承受最高达3 600 V AC/DC的持续电压和最高AC 20 kV瞬态电压，适合3 600 V以下的交直流高压系统检测。该隔离变送器已通过国家电气检测中心性能及电磁兼容试验，指标均达到或超过国外同类产品。
Abstracts:
According to the requirements of rail transit traction power supply and DC measurement, in view of the characteristics of frequent changes of the electric parameters of the DC traction system, adopting the pulse width modulation (PWM) method controlled by microcontroller unit (MCU) and making use of the printed circuit board (PCB) embedded with magnetic coupling transformer technology, isolated transmitter suitable for the detection of DC high voltage is developed, which could withstand up to 3 600 V AC/DC voltage and AC 20 kV transient voltage. It is applicable for detecting up to 3 600 V AC/DC high voltage system. The isolation transmitter has passed the performance and electromagnetic compatibility test of the National Electrical Testing Center, and its indicators have reached or exceeded similar foreign products.
