Product Description
Insulated Fiberglass Hot Stick Cutout Fuse Surge Arrester Hv Telescopic Insulation Operating Rod
Non Linear Carbon Discharge Resistor Type Discharge Rods are used to discharge dead system having limited fault levels and also to discharge the static & induced charges in the dead system or equipment, particularly in transmission lines, cables, transformers, reactors, large bus bar systems, switch-gears etc. The earthing lead is made up of special highly flexible braided copper cable with transparent sheath. Copper Hook and copper rod & Earth End Clamp of special alloy are provided.
Composition: discharge rod + single-phase ground wire + grounding clamp.
Uses:
The high voltage discharge rod can be usde for on-site high voltage test, especially in DC withstand voltage test, it should carry out a ground discharge for the accumulated charge on tested objects to ensure personal safety.
Portable telescopic rod model is easy to use in the outdoor high voltage test, especially in DC voltage test, to test the charge accumulation, to discharge, to ensure personal safety using the discharge rod discharge, is to ensure that the necessary for each test of the personal safety of the weapon. Portable telescopic rod is easy to carry, convenient, flexible, has the advantages of small volume, light weight, safe and reliable, is a safe tool of high voltage staff lack.
The use of methods
1. pull out the telescopic part of the portable telescopic discharge rod
2. the prepared grounding wire plug is inserted into the socket of the head end of the discharge rod, and the other end of the ground wire is connected with the earth, and the grounding is reliable
3. discharge should be completed after the test, the DC generator control box booster knob back to zero, at this time can observe the control box of the voltmeter voltage drop to 15KV ~ 20KV or so, can discharge
The 4. discharge should be the first to use the metal pointed front rod, go slowly on into disconnected power supply test samples. At this time the discharge rod release electricity is after discharge resistance of discharge. Then the discharge rod on the hook to hook the sample, second electricity.
Matters needing attention
1. of the sample capacitor discharge, should be in after the test, disconnect the power after the test, you should wait for a period of time, the charge on the cylinder and the sample times by itself on the self discharge. This can be observed on the control box of the voltage meter voltage the gradual decline in the fall, when voltage meter down to a lower voltage, usually in 5Kv ~ 15Kv, available discharge rod to gradually move to the sample nearby. First through the air gap free discharge, then you can hear a hissing sound, when no sound, with a tip to touch the discharge rod test, finally test direct grounding discharge.
The magnitude of the accumulated charge of the 2. large capacitance specimens is proportional to the size of the sample capacitor and the applied voltage, and is proportional to the time
3. after a few kilometers above the high voltage cable test, the discharge time is generally very long, and need to repeatedly discharge. Resistance capacity is large, need to order a large capacity of the discharge rod
4. is strictly prohibited without open test power to discharge the sample with the discharge rod.
5. strictly prohibit the use of foot and heavy extrusion rod, bending, breaking the discharge rod is strictly prohibited
6. prohibit the discharge rod damp, affect the insulation strength, should be placed in the dry place
High voltage ground wire classification
(1) high-voltage ground wire in accordance with the use of the environment can be divided into: indoor busbar grounding line and outdoor line-type ground wire .
(2) high-voltage ground wire in accordance with the voltage level can be divided into: 10KV ground wire, 35KV high voltage ground wire, 110KV grounding line, 220KV high-voltage ground wire, 500KV high-voltage ground wire
(3) According to the connection mode of FRP insulating rod, it can be divided into Connection straight type and Telescopic type
