Description

Technical Field

[0001] The utility model relates to a preassembled underground transformer box. Background Art

[0002] The pre-installed underground transformer box is a device used to pre-assemble and package the transformer and related equipment in an integral box. The box is designed for underground installation and can provide reliable power distribution and protection. The pre-installed underground transformer box generally includes a transformer box shell, a transformer box cover and a box heat dissipation device. The existing pre-installed underground transformer box has a box heat dissipation device welded to the transformer box shell, which has the following disadvantages: 1. It is large and inconvenient to carry during transportation, and it is not flexible to use in some narrow spaces; 2. Underground maintenance is relatively complicated. When components need to be replaced or the box heat dissipation device has been radiating heat for a period of time, dust is easily accumulated, which will greatly affect the heat dissipation effect and is not convenient for cleaning or maintenance. In view of this, the existing pre-installed underground transformer box is improved and optimized. Utility Model Content
