The XHSC-60Q Cable Fault Location Intelligent Bridge integrates both the burn-through and intelligent bridge functions into one device. In burn mode, it has a rated voltage of 60kV and a short-circuit current of 600mA, which can swiftly convert a high-resistance fault to a low-resistance fault. The intelligent bridge operates at a rated current of 600mA, significantly enhancing the accuracy of fault location. It is particularly well-suited for insulation fault location in high voltage, large-section, and long complex cable systems, such as in complex high voltage cables with GIS terminals and cross interconnections. Fault location can be completed quickly without the need to remove the GIS switch or short-circuit cross interconnections.
The intelligent cable fault location bridge can be used to locate all cable insulation and sheath faults except some short line faults.
Features:
1.The equipment adopts switching power supply to form high voltage constant current source, high voltage and stable current.
2.The bridge detection module is integrated with a large LCD screen display at high potential. The operating button on the panel is at ground potential and the bridge is operated through the insulation rod.
3.The special custom-made four-core high-voltage measuring cable with shield, the copper mesh braided shield layer is reliably grounded and safe to use. The four - end resistance measurement method avoids the error of lead resistance.
4.The high voltage constant current source and bridge are integrated in a portable pull rod plastic box. High voltage, light weight, easy to operate.
5.The bridge method has no blind spot compared with the wave reflection method, and is especially suitable for determining the breakdown points of short cables and near the ends.
6.High voltage and high current are especially suitable for the fault locating of insulation and sheath of complex high-voltage cable systems with large length and large section.
