Problems solved by technology

It can be seen that, on the one hand, the above methods involve large investment and high cost, but the effect is not certain
On the other hand, with the passage of time, the effectiveness of the resistance reducing agent, grounding module and ion rod, etc. will gradually weaken until they disappear, so the maintenance cost is also high

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. However, the examples given are not intended to limit the present invention.

[0024] A method for increasing the moisture content of substation soil, comprising the following steps:

[0025] Step 1. Survey the water level of the substation and determine the length of the grounding pipe.

[0026] Step 2. Make the ground pipe:

[0027] Use stainless steel pipe or hot-dip galvanized steel pipe as the grounding pipe, the diameter of the grounding pipe is 3-5cm, and holes a are left every 20-30cm on the wall of the grounding pipe.

[0028] Step 3, bury the grounding pipe:

[0029] Use a drilling rig to drill hole b in the ground. The diameter of hole b is the same as the diameter of the grounding pipe. Smash the grounding pipe into hole b. Fill the gap between the grounding pipe ...

Abstract

The invention relates to a method for improving transformer substation soil moisture content, and belongs to the technical field of transformer substation operating and high voltages. The method is used for lowering soil resistivity so as to lower the power frequency grounding resistance of a grounding grid. The method comprises the steps of surveying the water level of a transformer substation, determining the length of a grounding pipe, manufacturing the grounding pipe, burying the grounding pipe and welding the grounding pipe and a horizontal grounding grid. The method can achieve the function of gathering soil moisture, and the effect of lowering grounding resistance is very obvious.

Description

technical field [0001] The invention relates to a method for increasing the water content of substation soil, which is used for reducing the soil resistivity so as to reduce the power frequency grounding resistance of the grounding grid, and belongs to the technical field of substation operation and high voltage. Background technique [0002] In the power system, for the needs of work and safety, the shell of the power system and its electrical equipment, zero potential reference point, shielding layer, etc. are often connected to the earth, which is called grounding. The substation grounding system is the fundamental guarantee and important measure to maintain the safe and reliable operation of the power system and ensure the safety of operating personnel and electrical equipment. The power frequency grounding resistance value is an important technical index of the grounding system of the power generation substation. It is an important parameter to confirm the effectiveness...
