Measures to reduce the grounding resistance: in high resistivity soils (such as rocks, frozen and long sandy soil), to meet the provisions of the grounding resistance is difficult to reduce the grounding resistance can take the following measures: 1, low resistivity clay, black soil and sandy soil instead of the original high resistivity soil, generally replaced the upper third of the length of the grounding, the soil around .2 0.5 m or less, to increase the grounding sand soil buried depth also can not consider the soil deep freeze and dry the increase in resistance Coefficient of .3, artificial soil treatment, in general, appropriate to add salt in the soil, according to the experimental results, with salt soil, the sandy Clay resistance is reduced 1/3 ~ 1/2, sand resistance by 3/5 3/4, sand resistance can be reduced 7/9 to 7/8, for rocky soil, impregnated with a salt solution After 70 Henan increase its conductivity distribution room, electrical conductivity can be increased 1200 times granite, but the soil after the manual processing, reduce the thermal stability of the grounding, grounding accelerated corrosion, reducing the grounding life. Therefore, any time you can use a natural way to achieve the grounding resistance, generally do not use manual processing methods .4, after the frozen soil for carrying out manual handling, also when meet the requirements, the best body buried in the ground beneath the building Henan distribution room cost, or in the winter using fill method peat equipment arrangement in arrangement of substation equipment, we also present problems, even in violation of the provisions of the mandatory provisions, are only examples: 1) high, low-voltage distribution system map and plan inconsistent. Its manifestations are two types: one is a system diagram of a plan view of the cabinet, the opposite order of the screen. When look at the system diagram is for cabinet, the front panel, which is arranged from left to right 1,2,3 ...... n; and in the plan is for the back panel, which is arranged from left to right 1, 2,, 3 ...... n, inevitably backwards. The key is to avoid errors in the system and plan for the cabinet should be front screen arranged in the order from left to right. Second, there is a plan bus bridge between the double-face arrangement of distribution panel, but has not been shown in the system of FIG. 2) low-voltage distribution screen in the front, rear screen channel width does not meet the new regulatory requirements. After the screen sometimes after as Jinju wall 700mm, 1800mm apart when only low pressure drawer face double screen arrangement according to specifications GB50053-94 section 4.2.9 stipulates that the low-voltage distribution room in a row before the distribution panel screen layout, screen The minimum width of the channel: channel distribution room after the screens, both fixed and drawer 1000mm; its screen front channels, arranged in a single row of stationary distribution room is 1500mm Henan construction, drawer-type single-row arrangement of 1800mm, fixed type double-face arranged to 2000mm, double drawer face arranged to 2300mm. Only when the building wall in case when the column type local projections protruding portion channel width can be reduced 200mm.
