| titleOfInvention | Manufacture and manufacture method of hot dip galvanized ground rod for shim |
| abstract | 1. Scopen n n This standard applies to the method of manufacturing hot-dip galvanized ground rods installed in the ground of rock processing overhead lines.n n n 2. Types and Specificationsn n n Grounding rod is composed of basic part, connecting rod and lead terminal, and its type and standard are shown in Table 1.n n n TABLE 1n n n Type and specificationn n n n n n n n 3. Structure and materialn n n 3.1 Structure of ground rodn n n One). Grounding rod is composed of base, connecting rod and lead terminal.n n n 2). The main body shall be sufficiently resistant to the underground type, and the connecting rod connected with the main body ground rod and the lead terminal with the lead wire shall be of such a structure that the tightening torque is not loosened against the impact during the underground type.n n n 3). Earthing rods and connecting rods, and the surface and connecting parts of lead terminals shall be adequately corrosion-resistant to prevent corrosion by moisture and other foreign substances.n n n 4). Ground rod, connecting rod, and connecting part of lead terminal are processed to be in close contact with each other so that electrical resistance does not increase.n n n 5). Lead terminals and lead wires shall be connected electrically or mechanically so that the grounding effect is not impaired.n n n 6). Lead wire connection compression part inside lead terminal is copper plated to prevent corrosion and corrosion.n n n 7). The lead terminals and lead wires should not burst or fail at the time of type.n n n 3.2 Materialn n n One). The core of the connecting part of the foundation part, connecting rod and lead terminal shall be SM45C specified in KSD 3752 (Carbon structural steel).n n n 2). Lead wiren n n It shall be at least 7 / 2.6mm thick and specified in KSC 3101 (electric interlocking line) and shall be at least 300mm long.n n n 3.3 Zinc Platingn n n One). Each part is to be hot-dipped galvanized with the adhesion amount specified in Table 2 after removing impurities from the surface.n n n TABLE 2n n n Material and plating weightn n n n n n n n 2). Uniformity of plating: At least 6 times in the test solution until the end point is reached during the uniformity test.n n n 4. Shape and Dimensionn n n The shape and dimensions of the ground rod are based on the shape and dimensions of Figure 2 of the patent application.n n n 5. Test and inspectionn n n 5.1 Visual and structural inspectionn n n Visual inspection is to be examined in shape and shape, and structural inspection is to be in accordance with Par 3 and 4 by inspection of structure and dimensions.n n n 5.2 Material Testn n n The foundation part, connecting rod, and lead terminal are subjected to tensile test and bending test by KSD 3752 (mechanical carbon steel) SM45C, and the lead wire is according to KSC 3101 (electric interlocking wire).n n n 5.3 Connection tensile testn n n When connecting the foundation part and connecting rod or connecting lead terminal, foundation part and connecting part, it should not be abnormal when applying a tensile load of 1,300 Kg for 2 minutes.n n n 5.4 Tension Test of Lead Wiren n n It should not be abnormal when a tension of 350 kg is applied between the lead wire and the lead terminal for 2 minutes in the direction of the lead wire installation.n n n 5.5 Connection Resistance Test of Connection and Lead Terminal Junctionn n n When connecting the base and the connecting rod to each other and when connecting the base and the lead terminal to each other, the electrical resistance of the connecting part shall not increase more than 20% of the resistance of the rod of the same length.n n n 5.6 Current Testn n n When connecting the ground rod and flowing 2,000A of current from the lead wire to the ground rod for 1 second, it should be as follows.n n n One). The electrical resistance shall not increase more than 5% before and after this test.n n n 2). No abnormality should be observed when the test of 5.3 (Connected Tension Test) is carried out.n n n 5.7 Hot dip galvanized adhesion testn n n KSD 0201 "Method of Hot Dip Galvanizing" and adhere to adhesion test and adhesion test.n n n ○ As for the test method, double coating test (antimony chloride method) and uniform test (sulfur copper test) are carried out.n n n 5.8 Samplen n n Sample quantity by inspection and test item shall be extracted as follows for the same standard.n n n n n n n n 6. Displayn n n The following items shall be stamped or extruded in such a way that they cannot be easily removed from the ground rods.n n n One). Manufacturer name or abbreviationn n n 2). Year of manufacturen n n 7. Packingn n n Grounding rod and connecting rod should be bundled in 5 bundles each and 10 lead terminals should be bundled in bundles of 10, 2.0mm galvanized wire, light copper wire, or equivalent packing straps for easy transportation and handling. shall.n n n One). Manufacturer name or abbreviationn n n 2). Product Namen n n 3). Manufacturen n n <Related Standards>n n n ○ KSD 3752 (Carbon steel for machine structure)n n n ○ KSC 3101 (electric interlocking line)n n n ○ KSD 0201 (hot dip galvanizing test method) |
