A composite bushing assembly used in the teaching of power transmission high-voltage cable joints

Abstract

The invention discloses a composite bushing assembly used for the teaching of power transmission high-voltage cable joints. By arranging a top cover, a composite bushing, a cable assembly, a stress cone, a bottom plate and a tail pipe assembly, the height of the composite bushing assembly for assessment is reduced , reducing the weight of the composite sleeve assembly used for the assessment, reducing the length of the cable used for the assessment, and improving the safety of the assessment. Compared with the actual cable terminal assembly, the sleeve assembly is changed from porcelain to composite material, the total height is reduced from 2600mm to 1100mm in length, the weight of the sleeve assembly is reduced from 600KG to 65KG, and the length of the cable in the sleeve assembly is about 4.5 m is reduced to 3.3m, and the outlet rod used in the cable terminal assembly is changed from a one-piece structure to a split structure. The bottom plate of the cable terminal sleeve assembly is made of copper, and the weight is changed from about 73KG to aluminum alloy, and the weight is reduced to 23.5 KG, which greatly saves the assessment cost and improves the assessment efficiency.

Description

technical field [0001] The invention relates to assessment and teaching equipment in electric power systems, in particular to a composite bushing assembly used for teaching of power transmission high-voltage cable joints. Background technique [0002] As a typical representative of state-owned super-large power companies, power companies attach great importance to the ability evaluation of cable connector workers. The high-voltage cable joint workmanship assessment is costly, mainly because the trainees use new sets of materials for practice or assessment, which increases the cost burden of the enterprise. This is one of the key bottlenecks restricting the cable joint workmanship assessment. In the embodiment of the bushing assembly used in the actual industry, the bushing assembly includes a live running part and a bushing part, wherein the length of the live running part is 1200mm, and the bushing part is 1400mm, so the total height of the pipe assembly is 2600mm. And the...

AI Technical Summary

Problems solved by technology

When the bushing assembly used in the actual industry is used in the teaching of high-voltage cable joints for power transmission, because the live running parts of the bushing assembly in the prior art have no practical use, and the bushing assembly is made of ceramic materials, so the prior art The bushing assembly is heavy and high in height, so hoisting is required to assist in completing the teaching and training; at the same time, since the outlet rod of the bushing assembly used in the actual industry adopts an integrated structure, the entire outlet rod needs to be replaced after each teaching and training ; thus significantly increasing training costs
