CYGZ-711B cable fault detecting system
This instrument is a set of comprehensive cable fault detecting tester. It can test the cable's high resistance flash-over fault, high/low
resistance grounding, short circuit and break line, loose contact and other faults, especially suitable to test all kinds of types, different
voltage levels electric cables and communicating cables. It usually works with a high-voltage signal generator, portable and intelligent.
1. Technical Parameters of Intelligent Cable Fault Detector
(1) Sampling Method: low-voltage pulse method, impulse flash-over method, speed measuring method( optional for multiple times impulse).
(2) Sampling speed rate: 200MHz, 100MHz, 80MHz, 40MHz, 20MHz, 10MHz.
(3) Impulse Width: 0.05μs, 0.1μs, 0.2μs, 0.5μs, 1μs, 2μs, 8μs.
(4) Wave Speed Set: Cross-linked ethylene, polyethylene, oil immersed paper, no oil dripping and unknown type customized definition.
(5) Impulse High Voltage: 35kV and below.
(6) Measurement Distance: <60km, blind area≤1m.
(7) Resolution: 1m
(8) Measurement Accuracy: 1m
(9) Display Way: Industrial 10.4 inches colorful touching LCD.
(10) Operation Way: Touching operating, phsical knob operation.
(11) Analyzer Setting: scrolling screen, scale, save, recall, wave moving and other functions.
(12) Working Power: Built-in battery.
(13) Continuous Working: ≥8 hours(Use external power source is also ok).
(14) Save Function: can greatly reserve on-site datas and waveforms, and recall to use at any time.
(15) Waveform Analysis: all the high resistance fault waveforms performs as low-voltage pulse short-circuit fault waveforms, which is convenient to ananalyze the detent.
(16) Waveform Dealing: synchronizely display the fault point waveform and good phase total length open circuit waveform at the screen, which is convenient to same screen constrast and superposition contrast, and automatically judge the fault distance.
2. Technical Parameters of Sound Magnetism Digital Synchronous Squelch Locator
(1) Digital Display Distance: the max is 500m, the min is 0.1m.
(2) Rough Measurment Error is less than 10%, locating point error is zero.
(3) Electric magnetism channel gain >110dB(300 thousand times).
(4) Electric magnetism channel receiver sensitivity < 5μV.
(5) Sound channel audio frequency amplifier gain<120dB(It is 1000 thousand times when the Signal to noise ratio is 4:1)
(6) The squelch only receives fault point discharging earthquake wave.
(7) Sound and electricity synchronizely display monitoring: When locates on the site, the digital screen is repeatedly counted once under the action of the shock electromagnetic wave formed by the impact high voltage, and display the fault distance or full light(500m). At the same time, the seismic waves generated by sparks during shock discharge breakdown at the cable fault point are monitored by high impedance headphones to eliminate environmental clutter interference.
(8) When the sound wave transducer probe is switched to 15KHz electromagnetic transducer probe, it can accurately detect the cable's path and burying depth.
(9) Power Source: 6V lithium battery.
(10) Power consumption: <120mA, (0.7W)
(11) Working Environment: humidity 80%, temperature -10ºC~50ºC.
