Thumper cable outer sheath fault location tester
I. Introduction
60kV/600mA cable burning instruments cable thumper can emit a DC constant current voltage, forming a point heat source when the insulation is not good, and changing the insulation condition by the point heat source To achieve our ideal test status. A large number of practices have proved that this method is very effective in solving connector failures and other difficult faults. KC-60 CNC digital DC withstand voltage burn-through source (DC high voltage constant current power supply) is mainly used for high voltage cable insulation defects and high resistance leakage. The burn-through of the fault point causes the insulation resistance value of the poor insulation point and the high-resistance fault point to be greatly reduced, and the fault test condition is reached (the high voltage pulse can fully discharge). At the same time, it can also be used as a DC high-voltage power supply, which can perform DC withstand voltage tests on cables, capacitors, motors, porcelain bottles, etc. Used for DC withstand voltage of high-voltage electrical equipment, especially suitable for burn-through of high-resistance fault points of power cables, reducing the resistance at fault points.
1.DC withstand voltage test Can output 60kV DC voltage, can be used for DC withstand voltage test of high voltage cables and electrical equipment.
2.Burn-through cable failure points are particularly effective for breakdowns where high-voltage pulses such as high flashover resistance and intermediate connector water and moisture are difficult to penetrate..
