High voltage ground rod

Grounding rods are used in line and substation construction to prevent electrostatic induction and electric shock caused by nearby live objects or to ensure safety when the switch is accidentally closed. All performance indicators of the ground rod should comply with/industry technical standards. It is suitable for substation users and construction units such as power plants, power supply, telecommunications, railways, subways, etc. At the same time, special specifications of grounding rods can be customized as required.
The main components of the grounding rod include wire hook clamps, or busbar flat clamps, jumper short-circuit grounding tail wires, terminal noses, headers, grounding terminal clamps or five-proof locking chucks, grounding steel fibers and Composed of grounding operating wires, etc. The wire clip is made of high-quality copper (or aluminum) die-casting with a polished surface and is tightly connected to the wire nose. The wire is an important part of the "Portable Short-Circuit Grounding Rod".
High-voltage ground rod structure: The portable high-voltage ground rod consists of an insulated operating rod, wire clamp, short-circuited soft copper wire, ground rod, ground terminal, bus clamp, ground clamp or ground nail. The grounding rod is made of fiberglass epoxy resin, which has good insulation performance and high strength.
Usage environment: Indoor:
For indoor use, it is used for electrical grounding on electrical equipment. The wiring clamp adopts a flat spiral type, and the grounding method adopts a grounding rod clamp (connecting busbar and copper bar type). Low-voltage grounding rods are divided into two types: grounding rods for indoor equipment and grounding rods for outdoor lines. Generally, low-voltage lines adopt a three-phase four-wire system.
Outdoor:
The outdoor circuit adopts double spring type, and the grounding method adopts ground nail method.
.Installation operation
) Verify whether the voltage level of the ground rod is consistent with the voltage level of the operating equipment.
) Installation: Fix the double-eye copper nose on the grounding soft copper wire to the corresponding position of the electric clamp on the ground rod (the electric clamp has fixed and movable types), and connect the single-eye copper nose on the ground rod. The copper nose is fixed on the ground clamp or ground pin to form a complete set of ground rods.
3) The human body must not come into contact with the grounding rod or unbroken wire to prevent induction conduction.
) In places with high induced voltages, construction workers should also wear anti-static clothing.
) A grounding warning sign must be hung at the grounding point.
) When hanging the ground rod: connect the ground clamp first, then connect the electric clamp. When removing the ground rod, you must follow the procedure to first disconnect the electric clamp, and then remove the ground clamp.
) It is strictly prohibited to use a wire clamp instead of winding to create a ground short circuit.
) If there is a grounding point at the suspension point, a grounding rod clamp or a special copper rod should be used for grounding connection. If there is no fixed grounding point available, a temporary grounding point can be used. The depth of the grounding electrode buried underground should not be less than .
) Portable short-circuit grounding rods should be properly kept. Before each use, you should carefully check whether it is intact, the soft copper wire is not exposed, and the nut is not loose, otherwise it must not be used.
) The inspection cycle of the portable short-circuit grounding rod is once every five years, and the inspection items are the same as the factory inspection. After the portable short-circuit grounding rod that has passed the test is subjected to a short circuit, it should be judged based on the size of the short-circuit current and appearance inspection, and generally should be scrapped.
