变电站用温度信号在线监测单元
摘要：
本发明公开了一种变电站用温度信号在线监测单元，包括依次连接的温度采集单元、温度接收单元和计算机处理单元，温度采集单元包括温度传感器和信号发射器，所述温度传感器设置在母线连接部位，它通过信号线与信号发射器连接，所述信号发射器与温度接收单元信号连接，所述温度传感器与信号发射器明显隔离。本发明变电站用温度信号在线监测单元以其简单的结构，低廉的造价实现了温度传感器与信号发射器的分离，实现了温度传感器与信号发射器不同时提高温度，保障了信号发射器的正常运行，系统故障率进一步降低，可靠性高。
摘要（英）：

The invention discloses an online monitoring unit of a temperature signal for a transformer substation, which comprises a temperature collecting unit, a temperature receiving unit and a computer processing unit connected sequentially. The temperature collecting unit comprises a temperature sensor and a signal emitter. The temperature sensor is arranged at a bus connecting part and connected with the signal emitter through a signal line. The signal emitter is connected with the temperature receiving unit and the temperature sensor is obviously separated from the signal emitter. The online monitoring unit of the temperature signal for the transformer substation provided by the invention separates the temperature sensor from the signal emitter with a simple structure and low cost, improves temperatures of the temperature sensor and the signal emitter at different time points, ensures the normal operation of the signal emitter, and further reduces the failure rate of the system so as to achieve high reliability.
