电缆接头温度监测装置
摘要：
本发明涉及一种电缆接头温度监测装置，其特征在于丝状热电偶缠绕在电缆外表面，半导体温度传感器粘贴在电缆上，丝状热电偶和半导体温度传感器连接发射器的输入端，发射器的输出端连接接收器的输入端，接收器的输出端连接微处理器的输入端，微处理器的输出端连接闪光灯和扬声器；所述的发射器内设有信号滤波器和发射定时器；所述的接收器的内设有接收定时器。当高压电缆接头、母线连接处因过电流、接触不良等原因发生过热时，能发光报警，便于巡检人员及时查明故障原因以免故障范围扩大，减少人工排查时间，提高了工作效率，降低了成本。
摘要（英）：

The invention relates to a cable connector temperature monitoring device. The cable connector temperature monitoring device is characterized in that a filamentous thermocouple is wound around the outer surface of a cable, a semiconductor temperature sensor is sticked to the cable, the filamentous thermocouple and the semiconductor temperature sensor are connected with the input end of an emitter, the output end of the emitter is connected with the input end of a receiver, the output end of the receiver is connected with the input end of a microprocessor, the output end of the microprocessor is connected with a flash lamp and a loudspeaker, the emitter is internally provided with a signal filter and an emission timer, and the receiver is internally provided with a receiving timer. When the position where a high voltage cable connector and a bus are connected is overheated due to overcurrent, poor contact and the like, the device can emit light to give an alarm, and inspectors can conveniently find out the reasons of faults in time to avoid enlargement of the fault range, shorten the manual troubleshooting time, improve the working efficiency and lower the cost.
