Description

Technical Field

[0001] This utility model relates to the field of photovoltaic transformer box cover technology, specifically to a double-layer anti-condensation high-protection level welded integrated photovoltaic transformer box cover. Background Technology

[0002] European (American) style prefabricated substations, also known as outdoor complete substations or modular substations, are widely valued due to their advantages such as flexible assembly, ease of transportation, relocation, convenient installation, short construction period, low operating costs, small footprint, no pollution, and maintenance-free operation. In rural power grid construction (renovation), they are widely used in the construction and renovation of 10-110kV small and medium-sized substations (distribution substations), factory and mine substations, and mobile substations. Because they are easy to access load centers, reduce power supply radius, and improve end-point voltage quality, they are particularly suitable for rural power grid renovation and are hailed as the target model for substation construction in the 21st century.

[0003] Currently, among major complete electrical equipment manufacturers, the top cover structure of box-type substations is generally made of galvanized steel plate frame, with resin tiles covering the top. Box-type substations are typically used in residential areas, urban public substations, busy urban areas, and construction power supply areas, and are generally placed outdoors. Resin tiles have poor sound insulation, are prone to fading, and are susceptible to deformation or cracking under high and low temperatures, with a service life of only five to six years. In contrast, box-type substations generally have a service life of more than ten years. Replacing the tiles and returning them to the factory for repairs is troublesome and costly, consuming a lot of manpower and time. Furthermore, the tile structure provides poor protection, allowing insects and foreign objects to easily enter the interior of the box-type substation through the gaps in the tiles, affecting the safe use of the internal electrical cabinets, and in severe cases, even causing power outages, threatening the lives of monitoring and maintenance personnel. Utility Model Content

The frame body has a ventilation duct inside, with both ends of the ventilation duct connected to the two second frame sides respectively. The frame body has several lower sealing plates inside, which are connected to the frame body and the ventilation duct. The top of the frame body has several upper sealing plates, which are connected to the frame body and the ventilation duct.

[0015] The beneficial effects of this utility model are:

[0016] This utility model discloses a double-layered, anti-condensation, high-protection-level welded integrated photovoltaic transformer top cover, which effectively overcomes the shortcomings of resin tile top covers, such as short service life and low protection level, greatly improving the protection level and lifespan. The double-layered structure provides anti-condensation, heat insulation, and sound insulation. Laser welding eliminates the need for post-maintenance, reducing subsequent costs. The reduced overall height of the top cover allows for wider application and easier transportation. Solar photovoltaic panels can also be installed on the upper side of the top cover, aligning with current energy-saving and environmental protection concepts. The anti-condensation and high protection level effectively reduce safety hazards during equipment operation and personnel access.
