Product overview

The 35KV photovoltaic box transformer is a kind of backup power supply that our company combines with domestic and foreign advanced technology experience to provide a backup power supply using solar photovoltaic conversion technology. It converts the 690V voltage power generated by the photovoltaic generator into 35KV or 10KV through a step-up transformer. , sent to the system grid or users to complete the task of photovoltaic power generation. The box is equipped with a photoelectric and mains dual power automatic switching device, a transformer, a circuit breaker, and a power supply. The solar cells are connected to the input terminals of the solar panel and the DC/AC inverter voltage group respectively. The output terminal of the DC/AC inverter transformer is connected to The input end of the photoelectric/mains dual power automatic switching device is connected, and the photoelectric/mains dual power automatic switching device is connected to the mains power supply through a circuit breaker and a transformer. It is a 10KV power distribution system-secondary integrated outdoor device. This achieves the "four modernizations" of integration of the primary and secondary systems of the box-type substation, modular assembly, factory-based construction process, and simplified construction.

This product is used in various photovoltaic power generation sites and is the best supporting product for photovoltaic power generation systems. The products comply with standard requirements such as GB/T17467 "High and Low Voltage Prefabricated Substations" and DL/T537 "Technical Conditions for Ordering 6-5KV Box-type Substations".

Noodle product structural characteristics

The structure is compact and simple, takes up less space, and can be installed quickly. High and low pressure operation is easy. According to the requirements of the environment, a variety of colors of shells can be selected to make the box transformer harmonious with the surrounding environment; the fully sealed and fully insulated structure eliminates the need for insulation distance and reliably ensures personal safety. Cables are used for incoming and outgoing lines, eliminating the need for a power distribution room. Manufacturing costs and operating costs are greatly reduced.
