AI Technical Summary
Traditional dry-type transformer protective enclosures are susceptible to rain damage in outdoor or humid environments, affecting the equipment's service life. Furthermore, the integrated structure leads to high transportation and installation costs and low installation efficiency.
Design a detachable rainproof protective shell for dry-type transformers, including a rainproof top plate, a reinforced upper folded edge, a rainproof bracket, and a shell body. It is made of cold-rolled steel plate with a spray painting process and is connected by fasteners. The split design prevents rainwater intrusion and supports partial disassembly and quick installation.
It effectively prevents rainwater intrusion, extends equipment life, reduces transportation and installation costs, improves installation efficiency, reduces maintenance costs, and is suitable for humid environments.
