KDJK-10 cable grounding fault locator

Beskrywing

cable grounding fault locator

KDJK-10 distribution network overhead line single-phase grounding fault locator is suitable for 6-35kV overhead line single-phase grounding fault line, when the line is shut down due to single-phase grounding fault, the equipment can be accurately located at the docking point.

KDJK-10 single-phase ground fault locator for overhead lines in distribution network is a set of portable equipment, which can locate faults of multiple lines. The whole equipment consists of KDJK-10 transmitter, KDJK-A sensor, KDJK-B receiver and accessories. Nadat die foutlyn gesluit is, Die sender pas ultra-lae frekwensie hoë spanningsein op die lyn om die fout te herhaal, en die sensor word aan die lyn met 'n geïsoleerde staaf langs die lyn gehang om die sein op te spoor, en die data word draadloos aan die ontvanger op die grond oorgedra, en die ontvanger vertoon die meetresultaat. Voor die foutpunt, Die huidige bestaan ​​steeds, Na die foutpunt, Die stroom verdwyn. Die foutligging kan vinnig bepaal word deur 'n ruwe segmentering gevolg deur presiese bevestiging.

Produk eienskappe
1. Suitable for distribution network of small current grounding system, detecting single-phase metallic grounding, boogbegrafnis, oorgangsweerstandige aarding en ander foute van oorhoofse lyne.
2. Locate the line after it stops running, especially for faulty lines with cable branches.
3. By injecting detection signals into the fault phase of the line to determine the single-phase grounding fault point, reduce blindness and shorten the fault detection time.
4. In die toestand van lynkragversaking, Die enkelfase grondfout kan vinnig en akkuraat geleë wees, en die fout moet nie oorskry nie 1 meter.
5. Using dichotomy for detection, without the need for full line inspection, shorten the fault detection time.
6. As die lyn normaal loop, die lynladingstroom (0-1000A) kan opgespoor word.
7. Operate on the ground through the insulation rod, En daar moet 'n lontbeskermapparaat in die toestel wees om persoonlike veiligheid te verseker.
8. The device built-in ultra-low frequency composite signal source, Kragseinbron, high voltage signal source a variety of power modules, the device to achieve a variety of working modes.
9. Die toestel is toegerus met 'n verskeidenheid ontvangstelsels, wat mekaar nie inmeng nie, en kan gelyktydig of afsonderlik getoets word.
10. Apply a high voltage signal to make the fault repeat, the current signal is stable and easy to detect.
11. Ultra-low frequency signal avoids the influence of system distributed capacitance, and can locate faults with high resistance values.
12. Veiligheidsfunksies vir sender: Hoogspanning Start Blokkeringsfunksie, Uitset laat direkte kortsluiting toe.
13. The sensor uses high sensitivity sensor, open design, no need to close, easy to connect on the line.
14. Sensor en ontvanger draadlose kommunikasie -oordrag, Veilig en betroubaar.
15. The signal and data measured by the device may be saved to the system background, and the communication protocol is universal.
16. Die toestel het 'n verskeidenheid beskermingsfunksies en het goeie veiligheidstoetsprestasie.
17. Die sender kan hoofkrag gebruik, kragopwekker kragtoevoer, Sensor en ontvanger Droë batterykragtoevoer.
18. As die kragtoevoerspanning te laag is, Die alarm moet gevra word om te laai.
19. The size of the different frequency signal sent is adjustable.
20. The frequency and power signal are adjustable.
21. Operate through the insulated rod and have a fuse protection device inside.
22. The device built-in ultra-low frequency composite signal source, Kragseinbron, high voltage signal source a variety of power modules, the device to achieve a variety of working modes.
23. Klein grootte en ligte gewig van die sender; Die sensor is ontwerp om die volume en gewig te verminder, en dit is gerieflik om langs die lyn aan te sluit. Die ontvanger is ontwerp vir handheld.
24. The receiver uses a large-screen LCD display to display the sensor status, current waveform and current value.
