新闻动态
该装置可根据用户的要求配置以消除铁磁谐振
装置动作后，面板应显示故障类型（PT断线、金属接地或电弧接地）和相位，同时输出无源开关量接触信号。该装置可将相间和地间的各种过电压限制在3.5倍左右。本装置中的电压互感器可以为计量仪表和继电保护提供电压信号，可以代替传统PT柜。
After the device operates, the panel shall display the fault type (PT disconnection, metal grounding or arc grounding) and phase, and output the passive switch contact signal. The device can limit all kinds of overvoltage between phases and ground to about 3.5 times. The voltage transformer in the device can provide voltage signal for metering instrument and relay protection, and can replace the traditional PT cabinet.
6装置具有回忆功能，可以记录20个事件的时间和装置的动作状态。3.设备的附加功能1.设备可以根据用户的要求配置自动选线功能。小电流系统接地微机选线装置可增加选线功能。(2)该装置可根据用户的要求配置以消除铁磁谐振。可配备微机消谐装置保护PT。
6. The device has a recall function, which can record the time of 20 events and the action state of the device. 3. Additional functions of the device 1. The device can be configured with automatic line selection function according to the user's requirements. The microcomputer line selection device for small current system grounding can increase the line selection function. (2) the device can be configured according to the user's requirements to eliminate ferromagnetic resonance. It can be equipped with microcomputer harmonic elimination device to protect Pt.
