The cable outer sheath fault tester is especially suitable for 1.The high-resistance breakdown point of the cable after laying, especially the low-resistance linear high-resistance breakdown point, such as the linear high-resistance breakdown of the cable middle joint. 2. Flashover type breakdown point. After breakdown, the constant current source can maintain the arc, and there is a stable current through the bridge, the bridge has sufficient sensitivity. 3. Defects that have not been broken down but have low resistance, such as insulation defects that have low cable resistance but do not break down under operating voltage.
Feature
1.The cable outer sheath fault tester is designed based on the principle of MURRAY bridge. It can be used to locate the breakdown points of various wires and cables and the defect points without breakdown but low insulation resistance.
2.The equipment uses an electric voltage regulator and an R-type transformer to form a high-voltage constant current source, and the button operation increases and decreases the voltage. The no-load voltage is 5000V, the short-circuit current is 100mA, and the high-sensitivity amplifier and galvanometer are used to indicate balance. It forms a balance bridge with a proportional potentiometer, and the whole is placed at a high potential.
3.The measuring cable is a specially designed double-core high-voltage rubber cable. The four-terminal resistance measurement method avoids the error introduced by the lead resistance.
4.The operating knob on the panel operates the internal high voltage through the insulating rod. The entire panel is at a low potential.
5.The equipment is also equipped with a 12806 display screen, one-key operation, the input cable length can be automatically calculated, and the distance to the fault.
6.The high-voltage source and the electric bridge are integrated in a portable protective box. Therefore, the equipment has high voltage, light weight, convenient operation and safe use.
7.Compared with the wave reflection method, the bridge balance method has no blind spots, and is particularly suitable for judging short cables and the breakdown point near the end.
