Hongye - New Energy Photovoltaic Power Generation Special Box-Type Substation

The container-type integrated photovoltaic inverter grid-connected system (referred to as the integrated system) is a complete photovoltaic grid-connected system with an operating voltage of 0.4~35KV and three-phase AC 50Hz. The system integrates photovoltaic grid-connected inverters, transformers, high and low voltage switchgear, housings and other equipment into a single unit. It realizes the functions of DC power distribution, inverter grid-connection, voltage boost, AC power distribution, intelligent communication monitoring and so on. The product can replace the traditional "MW room + photovoltaic box change" model, widely used in distributed and centralized photovoltaic power stations, in line with GB 17467, NB/T 32004, GB1094.11, GB 7251.1, GB 3906 and other standards.

1. Photovoltaic inverter, transformer, switch cabinet integration, factory overall test, save site installation and commissioning time.

2. The shell adopts container design, without special lifting equipment, convenient transportation and installation.

1. Strong corrosion resistance: the shell is container-type and adopts high weather resistance steel plate, which has stronger corrosion resistance compared with standard carbon steel.

2. Thermal insulation: Thermal insulation panels are installed inside the chassis to provide good fire, thermal, and thermal insulation performance.

3. Effective ventilation and heat dissipation: the air inlet is specially designed to effectively prevent dust and sand from invading.

1. The dry transformer cast with epoxy resin is a flame retardant product to eliminate the danger of explosion and fire.

2. The dry-type transformer has passed the C2, E2 and F1 tests of the National Transformer Quality Supervision and Inspection Center.

1. Compared with the traditional "inverter room + photovoltaic box change" setting, the investment is reduced by 15% to 20%.

2. The number of installed bases is reduced from two to one.

3. Save 50% installation and commissioning time.

4. Copper wire is used between the inverter and the transformer to reduce the cable demand between the inverter room and the photovoltaic box. The structural optimization saves two low-voltage switching devices between the inverter and the transformer.

1. Product solutions can be customized according to the specific needs of customers, providing one-stop solutions to meet customer requirements.
