Description

Technical Field

[0001] This utility model relates to the field of indoor power distribution equipment technology, specifically to an indoor heat dissipation type power distribution box. Background Technology

[0002] A distribution box is an electrical device primarily used in power systems for power generation, transmission, distribution, and energy conversion. It controls and protects electrical equipment during these processes and is suitable for power plants, substations, petrochemical plants, businesses, and residential communities. Distribution boxes contain numerous distribution and metering devices, which generate heat during operation, causing the internal temperature to rise and potentially affecting the normal operation of electrical components.

[0003] The existing distribution boxes have the following defects: 1. The electrical components inside the box are not arranged reasonably, which makes it difficult for the internal air to circulate. Even if there are heat dissipation windows, the temperature inside the box is still high; 2. The heat dissipation windows are relatively complicated to install on the distribution box, and workers need to spend a lot of time to install them, which reduces the production efficiency of the distribution box. In addition, the dustproof performance of the heat dissipation windows is poor. Summary of the Invention
