Description

Technical Field

[0001] The present invention relates to the technical field related to the production of grounding down conductors, and in particular to a device for processing an anti-corrosion protective layer of an electric power anti-corrosion grounding down conductor and a method for using the same. Background Art

[0002] As the main component of the power system, the reliable lightning protection and grounding performance of power lines is the key to ensure the smooth operation of the power system. Flexible graphite composite grounding materials have completely realized the replacement of my country's traditional grounding materials, round steel and galvanized steel grounding materials, and effectively solved the technical bottlenecks of traditional grounding materials such as easy corrosion, large gap with soil, difficult construction and maintenance, and high life cycle cost. In recent years, flexible graphite composite grounding materials have completely realized the replacement of my country's traditional grounding materials, round steel and galvanized steel grounding materials, and effectively solved the traditional grounding materials. Easy corrosion, large gap with soil, difficult construction and maintenance, its application scope will be further expanded, but many operating units have reported that the following problems still exist in the actual application of graphite composite grounding bodies: (1) When the transmission line tower is struck by lightning, if there is no line arrester and the reclosing relay protection fails, the insulator flashes over and then causes power frequency continuous current, which makes the grounding down conductor bear the lightning current and power frequency continuous current. The power frequency short-circuit current intensity of pure graphite composite grounding materials is relatively small. At present, pure graphite grounding bodies have a certain risk of melting as grounding down conductors. (2) When the transmission line tower grounding grid uses graphite grounding material as the main grounding grid and galvanized steel grounding lead is used, there are two types of grounding materials in the tower grounding. Due to the corrosion potential difference between the metal steel and the graphite composite grounding body, the steel grounding material acts as the anode and the graphite acts as the cathode. The two form a chemical primary battery, which causes accelerated corrosion when the steel grounding material is connected to the graphite grounding material. There are also many corrosion problems in the application of graphite grounding grids for actual transmission line towers.

[0003] In order to solve the electrochemical corrosion and impact current tolerance problems that exist when current power projects use metal and graphite composite grounding bodies and other grounding bodies made of various materials, the industry generally uses metal above the ground and flexible graphite composite grounding materials below the ground. The two are connected by a clamp, and zinc strips are used as sacrificial anodes to delay corrosion. Among them, the metal grounding body above the ground and the connector part are coated with a thermoplastic layer for corrosion protection. The most common protection method in the prior art is to use a thermoplastic method to coat the surface of the wire body with an outer protective layer on the outside of the wire body. When the traditional wire outer protective layer forming equipment processes the outer protective layer, its various raw materials need to be weighed and added in batches, which is more troublesome, and the proportioning accuracy of the proportioning process is low, which affects the quality of the outer protective layer, thereby affecting the subsequent thermoplastic forming effect of the outer protective layer, resulting in a low yield rate of the grounding down lead, thereby affecting the product quality of the multi-material composite grounding down lead.

[0004] Therefore, in response to the above problems, the development of an anti-corrosion protective layer processing device for electric power anti-corrosion grounding down conductors has practical significance for improving the preparation process level of multi-material composite grounding down conductors, improving the molding efficiency and yield rate of multi-material composite grounding down conductors, etc. The product described in the patent has engineering application and industry promotion value.
