Overhead power line failure

XFH-JKXOverhead Wire Fault Locating Device for Small Current Grounding Faults, suitable for overhead lines in small current grounding systems. After a single-phase grounding fault occurs and the line is shut down, this device can be used to locate the grounding point.No Chinese content provided, please provide the text to be translated. Certainly.Positioning.

XFH-JKXIt is a portable device capable of pinpointing faults across multiple lines. The entire set consists of a transmitter (XFH-FSSensorsXFH-CG)、ReceiverXFH-JSThe assembly consists of the attachment. After the faulty line is shut down, an transmitter applies ultra-low-frequency high-voltage signals to the line to reproduce the fault. Sensors are hung on the line along the route using insulating poles to detect the signals, and the data is transmitted to the ground receiver wirelessly, where the receiver displays the measurement results. Before the fault point, the current persists; after the fault point, the current disappears. A preliminary segmentation can be conducted first.Please provide the Chinese content to be translated.

Feature Highlights

1.Our new solution is designed for distribution networks with small current grounding systems, capable of detecting various faults such as single-phase metallic grounding, arc grounding, and grounding through resistance transition in overhead lines.

2.Locating after the line is out of service, especially suitable for fault lines with cable branches.

3.Applying high-voltage signals to reproduce the fault, the current signals are stable and easy to detect.

4.Ultra-low frequency signals minimize the impact of system distributed capacitance, enabling precise location of high-resistance faults.

5.Transmitter Safety Features: High-voltage start interlock function, direct short-circuit output allowed.

6.The sensor utilizes high-sensitivity sensors with an open design, eliminating the need for closure, for easy attachment to the line.

7.Sensor and receiver wireless communication transmission is secure and reliable.

8.The transmitter can be powered by municipal electricity or a generator, while the sensors and receiver are powered by dry batteries.

9.The transmitter is compact and lightweight; the sensors are designed for miniaturization in size and weight, making them easy to hang along the route; the receiver is designed as a handheld unit.

10.The receiver features a large LCD screen, displaying sensor status, current waveforms, and current values.
