Project Description
Product Features:
Detect various ground faults such as single-phase metallic grounding and grounding through transition resistance of overhead lines.
The signal source adopts high-energy lithium polymer power supply, which can work continuously for no less than 12 hours.
The detector can easily measure the load current of the power supply line.
The detector adopts a U-shaped structure, which is convenient for hanging rod measurement. It is operated by an insulating rod, and there is a fuse protection device inside, which makes the operation safe and reliable.
Transmitter safety features: high voltage start lock function, output allows direct short circuit;
The LTJKX overhead line single-phase ground fault locator is used to quickly and accurately locate the grounding point after the fault line is powered off, which can realize the rapid search of the distribution network equipment in the event of a fault. It slao belongs to ground fault locator. Reduce the labor intensity of line maintenance personnel, save time and effort, and improve work efficiency, power supply reliability and economic benefits of power enterprises.
The company has combined the principles of domestic DC ground fault location technology, low current ground fault location, etc., invented the “S injection method” principle, and successfully developed the “high-voltage constant current open circuit, AC signal automatic tracking and positioning” technology, based on Fourier Algorithm, developed this product, and made major breakthroughs in 6kV, 10kV, and 35kV operation methods. It solves the problem of customer complaints caused by unable to restore power transmission due to long time no ground fault point and the economic benefit caused by the reduction of power sales; it also solves the problem of finding ground faults by manually climbing poles step by step due to crowded tactics And the problem of consuming a lot of manpower and material resources.
The current acquisition and reception wireless antenna is built-in to ensure that the clamp meter is absolutely insulated and reliable;
It is suitable for the power distribution network of small current grounding system to detect various faults such as single-phase metallic grounding, arc grounding, and transition resistance grounding of overhead lines;
Locating after the line is out of service, it is especially suitable for faulty lines with cable branches (10kv, 35kv overhead lines);
By injecting detection signals into the line fault phase, determine the single-phase ground fault point, reduce blindness and shorten the fault detection time
