Cable termite-resistant apparatus

Abstract

The invention discloses a cable termite-resistant apparatus. A cable is at a center position, the cable is arranged in an inner protection groove, the inner protection groove is externally provided with an intermediate protection groove, a drug charging space is arranged between the inner protection groove and the intermediate protection groove, upright columns are arranged between a lower drug charging space and a side drug charging space, the lower drug charging space communicates with the side drug charging space through a gap between the upright columns, and the outermost layer of the apparatus is also provided with an outer protection groove. The apparatus is buried below a ground surface when the apparatus is at a partial use state and extends out of the ground through a drug charging tube, and the drug charging tube is uniformly arranged for certain intervals along the length direction of the cable termite-resistant apparatus. The cable termite-resistant apparatus can effectively kill termites and prevents damage caused by the termites to electric power devices such as cables and the like.

Description

technical field [0001] The invention relates to a cable auxiliary device, in particular to a cable termite prevention device. Background technique [0002] In southern my country, especially the subtropical climate area, the climate is warm, humid and rainy, which is suitable for termite reproduction and growth, and is a high-incidence area for termite damage. Due to the environment and operation characteristics of directly buried high-voltage cables, they have been plagued by termites. Therefore, high-voltage cable failures caused by termites also occur from time to time. Therefore, termite prevention and control work for directly buried high-voltage cables is particularly important. Termites are insects with strong organization and high division of labor. In order to adapt to the environment and survive, it has certain life rules: [0003] (1) Group habitat. Termites are a kind of insects that live in nests. No matter what kind of termites, they all build nests and live ...

Problems solved by technology

[0015] (5) After termites bite through the outer sheath of the cable and reach the metal sheath, the formic acid secreted by termites accelerates the oxidation of the metal sheath, which is more likely to cause termite damage. After the metal sheath is damaged, the cable insulation layer is damp. Under the action of electric field, dendritic aging will be accelerated and the insulation strength will be reduced. In severe cases, single-phase grounding short circuit will be caused.

[0016] However, the above methods are slow to take effect. For areas with serious termite damage, developing a simple and efficient cable termite prevention device is the most urgent problem at present.
