Abstract

The invention discloses a manufacturing method of a modified graphite grounding body. The method comprises the steps: weaving modified graphite wires with the diameter of 2.5 + / -0.3 mm and stainless steel wires with the diameter of 5 + / -0.2 mm to form a flexible graphite grounding body, wherein the modified graphite wires are prepared through the following steps: firstly, taking 20-30 parts by mass of graphite for puffing, wherein the puffing temperature is higher than 950 DEG C, and the puffing time is 1-2 min; adding 3-6 parts by mass of asphalt, 7-10 parts by mass of elastic resin and 3-4 parts by mass of diacetone alcohol after puffing; adding 6-9 parts by mass of epoxy resin and 10-15 parts by mass of carbon fibers after the temperature is reduced to 100-200 DEG C; and acquiring graphite wires with the diameter of 2.5 + / -0.3 mm through pressing after sufficient mixing. The carbon fiber, the resin and the diacetone alcohol are added into the graphite, so that the conductivity is improved, the service life is prolonged, the flexibility is improved and the like.

Description

technical field [0001] The invention belongs to the field of flexible graphite grounding bodies, and in particular relates to a method for manufacturing a modified graphite grounding body. Background technique [0002] With the development of the power grid, the construction of various power facilities is increasing year by year, especially in recent years, with the development of UHV transmission projects, large-scale cross-regional transmission lines are becoming wider and wider. Our country has a large area and complex and changeable terrain. There are many dense lightning strike areas in the territory, especially in the southern region. Lightning strike is a relatively serious natural disaster, and the lightning protection grounding of transmission lines is directly related to the safety and stability of the power system. The graphite grounding body is the most commonly used non-metallic grounding body, which has good electrical conductivity and impact current tolerance...
