Description

Technical Field

[0001] The invention relates to a foundation well for placing power distribution equipment. Background Art

[0002] In the prior art, it is known that with the development of social economy, a large number of underground power equipment and cable foundation wells are needed. The cable well requires sufficient underground space to solve the problem of incompatibility between the distribution equipment and the surrounding environmental conditions. During use, the cable will generate heat when it is heated, thereby generating water vapor. These water vapors will form condensed water on the distribution equipment and cables, thereby reducing the distribution equipment and cables to a wet state, reducing the stability and reliability of the distribution network operation. And because the power supply equipment is all arranged in the underground space, this puts forward more stringent requirements on the environment in which they are grouped. In the invention patent application with application number 201610660918.8, a water-blocking weir is used to divide the well body into two spaces. Although this can prevent water backflow, it occupies a large space and also limits the placement of the power supply equipment. This is a shortcoming of the prior art. Summary of the invention
