Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete, in particular to a novel prefabricated concrete foundation switch station. Background Art

[0002] As we all know, the existing switch station is set up in the transmission line to strengthen the connection control of the distribution network and improve the flexibility and reliability of the overall power supply of the distribution network. The switch station is the connection and branch node of the entire power grid cable line. At present, most of the switch stations are prefabricated as a whole and directly hoisted to the construction site.

[0003] When the existing new prefabricated concrete foundation switch station is in use, a lifting platform is set up to lift the switch station so that the lifting platform can drive the switch station to rise and fall. As a result, the structural design under the lifting platform is too complicated. Once a problem occurs in a mechanical component or connector, the switch station needs to be lifted out of the underground as a whole for maintenance. The maintenance cost is too high and the maintenance is inconvenient, resulting in high limitations on its use. Utility Model Content
