Description
Technical Field
The utility model belongs to special power equipment's of photovoltaic power generation prepackage type transformer substation is applied to new forms of energy power generation engineering field, and specifically speaking is an integrated integration photovoltaic prepackage type transformer substation.
Background
With the increasing number of domestic photovoltaic power generation projects, the competition of investment cost is intensified, and the technical scheme is promoted to be promoted continuously. In order to respond to engineering requirements of users, a certain power equipment manufacturer integrates a photovoltaic combiner box (direct current cabinet), an inverter and an alternating current cabinet into a photovoltaic power generation combined transformer, so that the total floor area of power generation equipment is saved, and a secondary connection between field equipment is reduced. The structure of the transformer is characterized in that on the basis of the original 'product' -shaped combined transformer, the shell of the combined transformer for a low-voltage chamber and a common use is directly enlarged, and the inverter is connected with the alternating current cabinet by adopting a copper bar. The arrangement scheme has the advantages of simple manufacture and relatively low cost, but has the defects that the low-voltage AC cabinet, the DC cabinet and the inverter are arranged in a shared low-voltage chamber, a large amount of heat can be generated when the inverter works, if heat extraction is not timely, the normal operation of components in the AC cabinet can be directly influenced, and meanwhile, the inverter and the AC cabinet are arranged in the same operation chamber, so that the operation and the maintenance are not very convenient.
SUMMERY OF THE UTILITY MODEL
To the product scheme of the reduce cost of new energy market demand, optimization performance, the utility model discloses an integrated integration photovoltaic prepackage type transformer substation, direct current cabinet, dc-to-ac converter, the communication cabinet in this product not only integrated dc-to-ac converter room have integrateed combination formula transformer moreover, satisfy compact structure, the short period demand of mill's prefabrication, the utility model discloses a concrete technical scheme as follows: the utility model provides an integrated integration photovoltaic prepackage type transformer substation, including standard container, standard container divides into two parts, one part is as the dc-to-ac converter room, the dc-to-ac converter room adopts full seal structure, another part is as placing photovoltaic power generation combined transformer, photovoltaic power generation combined transformer direct mount does not have the container box body all around, directly exposes in the air, there are skeleton and the structure roof beam of container on upper portion, a secondary line between dc-to-ac converter room and the photovoltaic power generation combined transformer all adopts the cable of laying in the special intermediate layer of container base to link.
In the technical scheme, the primary and secondary connecting lines between the inverter room and the photovoltaic power generation combined transformer are connected by cables laid in a special interlayer of the container base. The product has a relatively compact structure, saves the total occupied area of power generation equipment, and simultaneously adopts an independent photovoltaic power generation combined transformer, thereby facilitating factory prefabricated production and butt joint connection. The inverter room has the advantages that the inverter room still adopts the arrangement scheme of the original inverter room and is independently separated from the alternating current cabinet of the combined transformer, the ventilation and heat dissipation performance of the inverter is good, the operation and maintenance of the alternating current cabinet and the inverter are not affected mutually, and the safety of operation and maintenance is greatly improved.
The utility model is further improved, a direct current cabinet, an inverter and a communication cabinet are integrated in the inverter room; photovoltaic power generation combined transformer includes hyperbaric chamber and low-voltage chamber, is provided with the AC cabinet in the low-voltage chamber, still includes oil tank and fuse room.
The utility model has the advantages that: the arrangement of each functional unit is more reasonable, and the safety of operation heat dissipation performance and maintenance operation of the inverter is met. The most important is that the standard container is adopted for factory prefabricated production, the overall structure strength is excellent, the export foreign marine transportation conditions are met, and meanwhile, the container can be stacked up and down, so that the transportation cost of export projects is greatly reduced.
