Overhead line small current cable ground fault locator/Distribution network single-phase grounding fault locating device
Product overview
KDJK-10A can only locate the fault after the fault occurs, and the fault is reproduced by applying high voltage to the fault line from the transmitter. The ultra-low frequency current flows from the transmitter to the fault point, enters the earth through the transition resistance and flows back to the transmitter. Along the line, sensors are connected to the line through insulated rods to detect the current. The sensor uses a high sensitivity sensor, and its magnetic circuit does not need to be closed, which is convenient to hang and take operations to a large extent. The sensor detects the current on the line, automatically adjusts to zero, converts the analog signal into a digital signal and transmits it wirelessly. The receiver on the ground receives the wireless signal sent by the sensor and displays the measurement results directly on the LCD screen. Before the fault point, the current continues to exist, after the fault point, the current disappears. The fault location can be quickly determined by rough segmentation (the long line is segmented by half method, and the branch line is tested at the branch point first) and then accurately fixed.
KDJK-10A is suitable for single-phase metallic grounding, arc grounding, transition resistance grounding and other fault types. Ultra-low frequency signal can avoid the effect of system capacitance, low resistance to high resistance faults can be adapted; Whether the line has branches, whether it is an overhead line branch or a cable branch, whether a transformer is attached to the line has no effect on the device.
KDJK-10A needs to connect the transmitter first in the use process, and needs to climb the pole to connect the sensor in the positioning process, so the use is slightly complicated, but the restrictions of the positioning test are very few, and the positioning accuracy and fault confirmation are high. KDJK-10A is a test equipment that solves difficult faults that cannot be detected by inspection after a grounding fault occurs in the line.
