Photo-voltaic Power Generation Step Up prefabricated substation
Product Overview
Photo-voltaic power generation used step up prefabricated substation makes step-up transformation substation prefabricated and assembled in factory workshop. It includes the step-up transformer, HV vacuum load switch and fuse combination electric appliance, LV switch, internal connection (cable, bus, etc.), power transformers and other auxiliary equipment. All above is equipped with a public shell, and it’s an outdoor sets of transformer substation which has passed the type test.It has advantages of complete set equipment, easy installation, short construction period, low operating cost, high structure strength, strong anti-corrosion performance.It is fully suitable for the beach, grassland, desert and other operating environments with poor natural conditions.
Product Structure Features
ü Functional Photo-voltaic Power Generation Prefabricated Substation integrates the advantages of European and American type products. It’s more suitable for the photo-voltaic power plants with following characteristics:
ü The isolation knife of the high voltage switch, the arc extinguishing chamber and the fuse chamber are separately placed, which solves the problem when the general switch needs to replace the fuse or the arc extinguishing chamber, the whole line power need to be cut. And it really realizes the function that the single set maintenance and not stopping other machines.
ü The HV switch to the transformer is connected by the bus-bar, and it solves the operational security problem with the cable connection.
ü For reference to the advantages of the pad-mounted transformer, the transformer radiator is installed in open type, which realizes the natural ventilation cooling performance, saves the power loss caused by forced ventilation, and eliminates the defect of the fan performance which is not reliable and easy to exceed the temperature to cause trip due to forced ventilation. It's also achieved that the charged body is totally sealed in the box so as to solve the dust problem;
