Description

TECHNICAL FIELD

[0001] The utility model relates to power transmission pipeline technical field, concretely is a kind of power transmission pipeline sealing structure. BACKGROUND

[0002] The transmission of electric energy is an important component of the overall function of the power system. Power plants and power load centers are usually located in different regions. Power plants are established in places where water, coal and other primary energy resources are suitable, and electric energy can be transmitted to load centers far from power plants through power transmission, so that the development and utilization of electric energy can transcend geographical limitations. Compared with other energy transmission methods, power transmission has the advantages of small loss, high efficiency, flexibility, easy adjustment and control, and reduction of environmental pollution. Power transmission lines can be divided into overhead power transmission lines and underground power transmission lines according to their structure. The former is composed of line towers, conductors, insulators and other components, and is erected on the ground. The latter mainly uses cables and is laid underground (or underwater). Power transmission can be divided into direct current transmission and alternating current transmission according to the nature of the transmitted current.

[0003] The existing power transmission pipeline connection is usually provided with a protective structure for sealing protection to prevent short circuit caused by water seepage at the power transmission pipeline connection after long-term use. Although the existing power transmission pipeline sealing structure can prevent water from directly contacting the power transmission pipeline, there is still a risk of short circuit caused by contact between the accumulated water inside the power transmission pipeline and the worn power transmission pipeline after long-term use. Therefore, a power transmission pipeline sealing structure is proposed. SUMMARY
