Introduction
SPVG-J photovoltaic AC power distribution cabinet is an important part carrying a centralized inverter and a booster transformer or an AC combiner box and a booster transformer. Its incoming line adopts breaker input or direct input, with the output adopting the breaker or load-disconnector switch. Its bus adopts electroplated or purified bus connection. Grade 2 lightning protection is provided. The max system rated voltage is AC690V. The protection level is IP40 indoors and IP65 outdoors. Cables for secondary measurement and control include those over 2.5mm2 for current, over 1.5mm2 for voltage and over 1.0mm2 for control. The measurement current transformer is of Grade 0.5. The metering transformer is a current transformer of Grade 0.2S. Related functions or the like can be added according to customer requirements. With professional electric design and component selection, the product brings safe, concise and nice internal cabinet structure, which facilitates easy wiring on site and maintenance and ensures long-time stable work of equipment.

Use conditions
>Fixed mounting design or plug-in design;
>It can be combined with breakers and components of the company or other brands to form functional units; with excellent technical performance, it is safe and reliable;
>It can be respectively constituted into various standard unit modules, so customers can make selection and assembly at will;
>With inter-area isolation and mutual isolation between incoming and outgoing lines of functional units, it effectively enhances safety protection performance;
>It adopts a combined assembly structure. All structural parts of the frame are firmly connected by screws. The frame, door and panels are treated by phosphating and then static spraying. Those without spraying are plated and passivated;
It can meet requirements of various components as well as different working environments, and reach corresponding protection levels;
>The framework adopts steel plates. The framework can be equipped with holes of mode number 25mm for various usage expansion. Incoming modes include upper and lower side incoming;
>High breaking capacity, good dynamic and thermal stability, flexible and convenient electric scheme combinations, high practicability;
>Light weight, high mechanical intensity and assembly accuracy, nice appearance.
