一种用于变电站中变压器和GIS的状态监测系统
摘要：
本实用新型公开了一种用于变电站中变压器和GIS的状态监测系统，包括变压器、连接该变压器的若干第一智能电子设备、GIS、连接该GIS的若干第二智能电子设备、分别连接各第一智能电子设备和各第二智能电子设备的交换机以及连接所述交换机上位机；每个第一智能电子设备均包括第一传感器、第一滤波器、第一信号放大器、第一A/D转换器、DSP、第一FPGA、第一电源和第一RAM；每个第二智能电子设备均包括第二传感器、第二滤波器、第二信号放大器、第二A/D转换器、MCU、第二FPGA、第二电源和第二RAM。本实用新型通过对采集信号进行滤波、放大等处理，避免了因电磁干扰而造成的采集信号缺失、结果不准确的情况。
摘要（英）：

The utility model discloses a state monitoring system for a transformer and a GIS of a transformer station, which comprises the transformer, multiple first intelligent electronic devices connected with the transformer, the GIS, multiple second intelligent electronic devices connected with the GIS, a switch respectively connected with the first and second intelligent electronic devices, and a host computer of the switch. Each first intelligent electronic device comprises a first sensor, a first filter, a first signal amplifier, a first A/D converter, a DSP (Digital Signal Processor), a first FPGA (Field Programmable Gate Array), a first power supply and a first RAM (Random Access Memory); and each second intelligent electronic device comprises a second sensor, a second filter, a second signal amplifier, a second A/D converter, an MCU (Microprogrammed Control Unit), a second FPGA, a second power supply and a second RAM. According to the utility model, acquired signals are processed, amplified and the like, thereby avoiding signal acquisition loss and inaccurate results caused by electromagnetic interference.
