Description
Technical Field
The utility model relates to the field of cable terminal platforms, in particular to a self-supporting cable terminal bracket platform.
Background
The transmission line has two types of overhead lines and cable lines. The overhead line has the characteristics of simple structure, convenience in erection, large conveying capacity, large land occupation area of a power transmission corridor, easiness in causing electromagnetic interference to the surrounding environment and the like, is suitable for long-distance transmission, and is widely suitable for environments such as the field and the suburbs of the city. The cable line is not easily influenced by the environment, has high power transmission reliability, does not occupy an air corridor, has the advantages of long service life, large communication capacity, stable transmission quality, small external interference, good confidentiality and the like, and is more suitable for dense people areas such as cities and the like. In areas such as outgoing lines of transformer substations (power plants), dense transmission channels, important cross-over and the like, part of sections need to be erected from the overhead state to be laid in the ground by cable lines due to the limitation of air corridors.
At the splicing position of the overhead line and the cable line, a cable terminal tower needs to be arranged. A platform is required to be arranged on the side edge of the cable terminal tower and is used for supporting a cable terminal (a device which is assembled to the head end and the tail end of a cable line and used for completing connection with other electrical equipment, such as an outdoor terminal, an indoor terminal, an elbow-shaped terminal and the like), a lightning arrester (an electrical appliance for protecting the electrical equipment from high transient overvoltage, limiting follow current time and limiting follow current amplitude) and the like; the lower part of the platform needs to be provided with a bracket for leading the cable down. At present, the platform is usually in an integral type arranged on a tower body, the platform of the integral type is not flexible in arrangement, and the platform structure needs to be rearranged when the height of an iron tower is increased or decreased; in addition, due to the stress characteristic, the tower body integral platform structure always enables the iron tower to have higher tower weight and poorer overall economy. For the transformation project of leading overhead lines into the ground, if the existing iron tower is transformed into a cable terminal tower, when a tower body platform mode is adopted, the transformation difficulty of the old tower is higher, and the engineering implementation is more difficult.
In the field of existing cable terminals, for example, "a cable terminal wire grounding structure for iron tower" with patent No. CN 207530502U provides a wire grounding structure, and is not provided with a comprehensive platform structure, and only can realize partial functions similar to those of a cable terminal in terms of functions, but does not consider carrying a lightning arrester and a counter-pull string in terms of structural planning, and the function is single, which will limit the application thereof to a great extent. In addition, as an independent straight post type cable terminal platform provided in the patent with the patent authorization number of CN 207863569U, the function is relatively single, and the main body support is a steel pipe rod structure, so that the weight is heavier and the economy is not good.
