Problems solved by technology

[0003] The logistics and transportation of underground pipe corridors are inseparable from the support of electric power, but at present, in the construction of logistics and power for underground pipe corridors, almost all of them use ordinary electrical cabinets on the market to complete the power conversion task; due to the heavy logistics and transportation tasks of underground pipe corridors, relatively large power is required The power components are converted to high and low voltage; the traditional electrical cabinet has a low level of safety protection, so it is difficult to meet the needs of the logistics development of the underground pipe gallery, and there are many safety hazards in use
