KDJK-10 cable grounding fault locator

Opis

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. After the fault line is shut down, the transmitter applies ultra-low frequency high voltage signal to the line to make the fault repeat, and the sensor is hung on the line with an insulated rod along the line to detect the signal, and the data is transmitted wirelessly to the receiver on the ground, and the receiver displays the measurement result. 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 followed by precise fixing.

Značilnosti izdelka
1. Suitable for distribution network of small current grounding system, detecting single-phase metallic grounding, ozemljitev obloka, prehodni upor ozemljitve in druge napake nadzemnih vodov.
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. V stanju izpada električne energije, the single-phase ground fault can be quickly and accurately located, and the error must not exceed 1 meter.
5. Using dichotomy for detection, without the need for full line inspection, shorten the fault detection time.
6. Ko linija teče normalno, tok obremenitve linije (0-1000A) mogoče zaznati.
7. Operate on the ground through the insulation rod, in v napravi mora biti zaščitna naprava z varovalko, da se zagotovi osebna varnost.

14. Prenos brezžične komunikacije s senzorjem in sprejemnikom, varno in zanesljivo.
15. The signal and data measured by the device may be saved to the system background, and the communication protocol is universal.
16. Naprava ima različne zaščitne funkcije in ima dobro varnostno testiranje.
17. The transmitter can use mains power, generator power supply, sensor and receiver dry battery power supply.
18. When the power supply voltage is too low, the alarm should be prompted to charge.
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, vir napajanja, high voltage signal source a variety of power modules, the device to achieve a variety of working modes.
23. Small size and light weight of transmitter; The sensor is designed to reduce the volume and weight, and it is convenient to connect along the line. The receiver is designed for handheld.
24. The receiver uses a large-screen LCD display to display the sensor status, current waveform and current value.
