保定电气厂

适用于35kV以下各种电压等级，多个谐振频率(1/3分频、1/2分频、工频、3倍频)均适用；

Used in the below 35 kv voltage grade, multiple resonance frequency (1/3, 1/2 frequency, power frequency, frequency three times) all applicable; 

无需整定和调试，开机自检后自动进入运行状态，设备维护量低；

Without setting and debugging, boot after self-checking automatically enter the running state, the equipment maintenance cost is low; 

在过电压，单相接地等故障时给出报警信号并显示保存相关信息，可存储20重故障信息供追忆和显示；

Single-phase grounding overvoltage, such as failure alarm signal and display the saved information, can store 20 heavy fault information for remembrance and display; 

实时显示，记录铁磁谐振发生时间及相关参数(电压和频率)，并在铁磁谐振发生时进行快速消除；

Real-time display and record the ferromagnetic resonance happened time and related parameters (voltage and frequency), and quickly remove the ferromagnetic resonance occurs; 

以接点闭合方式输出或语音报警输出；

In close contact way output or voice alarm output; 

可以配置通信接口(RS-485接口)；

You can configure the communication interface (RS - 485 interface); 

可以配置微型打印机以及时打印输出故障报告(故障类型、故障时间及4种频率的电压分量)。

When you can configure the micro printer and print failure report (fault type, fault time and four kinds of frequency voltage components).
