一种用于脐带缆电缆故障的定位装置及使用方法
摘要：
本发明涉及一种用于脐带缆电缆故障的定位装置及使用方法，它包括行波信号耦合器、前端控制单元和上位机。行波信号耦合器串联在被测脐带缆电缆线路中，行波信号耦合器与前端控制单元电连接，前端控制单元与上位机电连接。上位机向前端控制单元发送故障定位脉冲，前端控制单元产生行波信号，并经行波信号耦合器传输至脐带缆，经脐带缆故障点反射回的行波信号经行波信号耦合器和前端控制单元传输至上位机。行波信号耦合器由线路阻波器、耦合电容器和结合滤波器构成。前端控制单元包括CPU模块、行波接收和发送模块和高速数据采集单元。本发明能够快速对电缆故障进行定位，缩短故障修复时间，提高可靠性。
摘要（英）：

The invention relates to a locating device for a cable fault of an umbilical cable and a use method thereof. The locating device comprises a travelling wave signal coupler, a front-end control unit and an upper computer. The travelling wave signal coupler is connected in series in the cable line of the tested umbilical cable. The travelling wave signal coupler is electrically connected with the front-end control unit. The front-end control unit is electrically connected with the upper computer. The upper computer transmits fault locating pulses to the front-end control unit. The front-end control unit generates travelling wave signals and transmits the travelling wave signals to the umbilical cable through the travelling wave signal coupler. The travelling wave signals reflected back by the fault point of the umbilical cable are transmitted to the upper computer through the travelling wave signal coupler and the front-end control unit. The travelling wave signal coupler is composed of a line trap, a coupling capacitor and a combining filter. The front-end control unit comprises a CPU module, a traveling wave receiving and transmitting module and a high-speed data acquisition unit. The fault of the cable can be quickly located by the locating device so that fault recovery time can be shortened and reliability can be enhanced.
