Description
Technical Field
The invention belongs to the technical field of grounding, and particularly relates to a vertical grounding device suitable for high soil areas.
Background
Currently, grounded grounding means that the neutral point of the electrical system and electrical device, the exposed conductive portion of the electrical equipment, and the external conductive portion of the device are connected to ground via conductors. Can be divided into working grounding, lightning protection grounding and protection grounding; the working ground is set by the power system operation requirements (e.g., neutral ground), so that normally there will be a long-term flow of current through the ground electrode, but only an unbalanced current of a few amperes to a few tens of amperes. When a system has a ground fault, thousands of amperes of working current can flow through a grounding electrode, but the current can be cut off by a relay protection device within 0.05-0.1s, and even if backup protection is adopted, the action is generally within 1 s; lightning protection grounding is grounding provided for eliminating dangerous effects of overvoltage, such as grounding of lightning rod, lightning conductor and lightning arrester. The lightning protection grounding can only flow current under the action of lightning impulse, the amplitude of the lightning current flowing through the lightning protection grounding electrode can reach dozens to hundreds of kiloamperes, but the duration is short; the protective grounding is grounding which is arranged for preventing equipment from being endangered to personal safety due to insulation damage and electrification, such as a metal shell of power equipment, a reinforced concrete pole and a metal tower. The protective earth only allows the flow of current in the event of a breakdown of the insulation of the installation, the value of which can vary within wide limits.

however, it is not preferable to increase the area of the grounding grid to reduce the resistance because of limited urban land resources and expensive land price; under the condition of low resistance, even if a resistance reducing agent is used, the resistance reducing effect is not obvious, and the manufacturing cost is high; the ground downlead of the grounding device of the power transmission line tower adopts round steel in the prior art, the round steel can be corroded after being used for a period of time, the self resistance of the round steel is increased after the round steel is corroded, the conductivity is reduced, lightning stroke accidents are easy to happen, and the power transmission line is tripped; on the other hand, after long-time research, the area with serious corrosion of the round steel down lead is concentrated at the contact interface between soil and air, the flexible graphite grounding down lead has good corrosion resistance and is the best substitute of the round steel down lead, but the connection realization difficulty of the flexible graphite grounding down lead and the underground round steel grounding net is higher, and the flexible graphite grounding down lead cannot be realized through a welding process;
even use connecting tool to connect flexible graphite ground connection downlead and secret round steel ground net, for example use screw, hoop etc. to connect, or carry out the indent processing according to the shape of the line body, all need operate with the help of the instrument, if the instrument damages, is improper or will cause the unable completion of connection operation when not carrying.
