Cable identification instrument Troubleshooting steps 1. Cable identification instrument After the fault occurs, the repairman should prepare working tools: 1. A set of cable fault tester 2. Cable fault, cable, cable head, and crimping tube have the same specifications. 3. Two small ropes, two large ropes and four cable identifiers Troubleshooting Step 1. After a cable identifier fault occurs, the repairman should prepare working tools: 1. A set of cable fault testers 2. Cable faults, cables, cables Head, crimping pipe specifications are the same. 3. Two small ropes, two large ropes and four sets of landing tools.
4. Check the electric pen, safety sign and ground seal 2 groups. 5. Lighting tools, communication tools, wire cutters, tie wires, iron wires, saw bows, phase sequence belts, blowtorches. 6. Power generation equipment.
7. Multimeter, insulating vibrator, anti-aging wire, wire ends, crimping pliers, tape, sandpaper, round. 2. The division of labor and the process of the cable identification instrument can be grouped at the same time. 1. According to the dispatch instruction, the power failure will be cut off at the first time.
2. Notify Baodong maintenance workshop according to the fault situation. 3. Prepare work tools and ship spare transformers. 4. When restoring, pay attention to site safety and the phase sequence of the cable terminal connection.
Three. Three considerations 1. The copper shield is wrapped with insulating tape to prevent copper in the manufacture of cable terminations. The shroud is loose and temporarily secured and should be removed when the heat stress tube shrinks. 2. The electrical stress control tube (called stress tube) is placed at the rupture of the shielding layer to disperse the electric field stress of the crack (power line) to ensure the reliable operation of the cable.
3. Safety protection should be provided during the stress test. The Cable Identifier is a comprehensive cable fault detection instrument. It can test cables for high impedance flashover fault, high and low resistance grounding, short circuit and cable disconnection, poor contact and other faults.
If equipped with a sound measurement legal point meter, the exact location of the fault point can be accurately determined. It is especially suitable for testing power and communication cables of various types and voltages.
