Example Embodiment

[0025] Example 1

[0026] Such as figure 1 The shown pre-installed ground wire fastening device aims to provide a prefabricated ground wire installation and fastening device that simplifies the existing operation process. The specific design structure, principle and work flow are described below.

[0027] The outer cylinder 1 and inner cylinder 2 of this device are the installation bases. In the prior art, when the grounding wire is used, the soil resistivity should be measured first, and then the grounding trench should be set out according to the design drawing requirements and the site topography and landform conditions, and the excavation line of the grounding trench should be drawn. The device can determine the length of the outer cylinder 1 and the inner cylinder 2 according to the resistivity of the soil to determine the grounding safety. Such as image 3 As shown, the outer cylinder 1 is movably mounted on the inner cylinder 2. A fixing groove 14 is provided on the outer ...

Abstract

The invention relates to the field of grid electrical appliances, in particular to a pre-installed grounding wire fastening device so that a problem that the existing grounding wire installation operation process is complicated can be solved. The device comprises an outer cylinder and an inner cylinder. The outer cylinder is nested to the outer surface of the inner cylinder movably; a metal material-based upper guide block is nested to the upper part inside the inner cylinder; and a metal material-based lower guide block is nested to the lower part inside the inner cylinder. A wire hook and ahandle are fixed on the upper guide block. The upper guide block and the lower guide block are connected by an inner wire. A bottom platform is arranged at the bottom of the inner cylinder. A plurality of movable disks are installed between the outer cylinder and the bottom platform. The pre-installed grounding wire fastening device has the following beneficial effects: the prefabricated groundingwire fastening device is employed; with the expandable movable disk structure, the ground wire is grounded firmly; and objectives of great convenience in installation and simple operation are achieved.

Description

technical field [0001] The invention relates to the field of power grid electrical appliances, in particular to a pre-installed grounding wire fastening device. Background technique [0002] For the needs of work and safety in the power system, it is often necessary to connect some parts of the power system and its electrical equipment to the earth, which is grounding. The "ground" in the power system refers to the earth conductive substance whose potential at any point is conventionally taken as 0. Grounding refers to the conductive connection (metallic connection) between the circuit (equipment) and the earth or some conductors that replace the earth. The grounding of the power system includes the grounding of the high-voltage system and the grounding of the low-voltage system. The low-voltage grounding system is divided into five ways: IT, TT, TN-C, TN-S and TN-C-S according to the grounding system. [0003] The existing grounding wire uses cement blocks as a fixed refe...
