Abstract

The invention relates to an important equipment independent grounding device, which comprises a grounding grid, a grounding wire, a clamp and a grounding electrode, and is characterized in that the grounding grid comprises tin-plated copper stranded wires which are vertically and horizontally arranged, the tin-plated copper stranded wires form a grid-shaped structure, the tin-plated copper stranded wires are connected through the clamp, the grounding electrode is perpendicular to the grounding grid, and the grounding electrode is connected with the grounding grid through the clamp. The grounding electrode is connected with a grounding grid, one end of the grounding wire is connected with the grounding grid through a clamp, the other end of the grounding wire is connected with the grounding electrode reserved in a wall body through the clamp, the grounding wire is arranged in the clamp, and the clamp is wrapped by a PVC electrical adhesive tape. The construction method comprises the following steps: reserving a grounding electrode for fixed installation; laying a grounding wire; the grounding grid is connected with a grounding wire; constructing a grounding electrode and a grounding grid; and testing the grounding resistance. The grounding device is mainly composed of the tinned copper stranded wire, the PVC galvanized round steel, the clamp and the grounding electrode, the grounding resistance can be effectively reduced by applying the grounding device to important equipment, and the safety production requirement is met.

Description

technical field [0001] The invention relates to the technical field of grounding devices, in particular to an independent grounding device for important equipment and a construction method thereof. Background technique [0002] With the rapid development of public health, scientific research and medical projects are rising by leaps and bounds, among which the requirements for lightning protection and grounding of buildings and precision equipment are getting higher and higher. The grounding requirements of buildings and precision equipment are strict (the grounding resistance value is less than 0.5Ω). If the lightning protection grounding setting does not meet the requirements, it will cause irreparable losses to medical equipment and precision equipment. SUMMARY OF THE INVENTION [0003] In order to solve the problems raised in the above background art, the present invention provides an independent grounding device for important equipment and a construction method thereof...
