CFL-2 TDR Method Underground Power Cable Detector Cable Fault Locator adopts an integrated design, which is convenient and flexible to move.
Safe operation, simple wiring: the output voltage is adjustable, and the high-voltage output is directly connected to the tested cable, it is safe for operation and simple for wiring.
A 7-inch color touch screen is used to display the working status, voltage and discharge of the instrument, electric current and discharge frequency, preset voltage, automatic voltage boost, shutdown automatic discharge of residual power. The discharge voltage and current value are displayed directly.
Integrated combination: integrated multi-gear DC high-voltage generator, multi-gear high-voltage capacitor, high-voltage discharge device, safety discharge device, Arc reflection automatic ranging system, and large-capacity lithium battery.
Automatic safety discharge: The instrument has its safety discharge mechanism, which can complete the high-voltage automatic safety discharge after the test, and can monitor the discharge at the same time process, to avoid the potential danger caused by the user's direct manual operation of high-pressure, safe and secure.
There are three configurations of capacitor levels: 1st gear: 32kV/4uF; Two-step switching: 32kV/4uF and 16kV/16uF; Three-gear cut Exchange: 32kV/4uF, 16kV/16uF, 8kV/64uF
Three modes: DC, single, and cycle three modes, the cycle discharge time and discharge frequency are actively controllable, and the discharge cycle is OK to set up. It supports continuous high-voltage impulse discharge, and the discharge voltage is not limited by the ball gap distance.
It can be burned through, and can be used for cable to withstand voltage tests.
With a constant current output function: it can provide a constant current source for the digital positioning bridge.
Silent discharge: no contactor mechanical noise, proximal fault location is not affected.
Built-in lithium battery: Built-in lithium battery solves the problem of outdoor operation and no power supply on-site.
Safety guarantee: It has the function of grounding protection, and when the contact with the protective ground is poor, the device cannot be started at high voltage to protect equipment and personnel safety.
Emergency stop button: The high-voltage output line is made of shielded special cables, which can withstand voltages up to 60KV, and has an "emergency stop" switch.
Overcurrent protection function: prevent the equipment from burning out and causing overcurrent impact on the power grid, and ensure the safety of the operator at the same time.
