Standard smart substation: equipment like U disk, like "plug and play"

Compared with ordinary substations, standard distribution smart substation to achieve a primary equipment and secondary equipment, secondary equipment and secondary equipment like U disk, like "plug and play."

July 10, Zhangzhou, Fujian Heng Cang 110 kV substation on the 1st transformer after full voltage shock 5 times officially put into operation. Heng Cang 110 kV substation is the State Grid Corporation of the first batch of 5 standard distribution smart substation project is one of the first standard distribution smart substation in Fujian. Its completion and commissioning not only satisfied the electricity demand of Zhangzhou Taiwanese investment zone in time, but also provided valuable construction experience for promoting standard distribution smart substation in Fujian and the whole country.

Deepening the standardization of design, integrated application of new technologies is the building of Heng Cang substation highlights.

Constant Cang substation equipment and secondary equipment, secondary equipment and secondary equipment between the standardized connection, only need to use the relevant joints like U disk inserted into the correct position, to complete the equipment docking, to achieve secondary wiring "that is Plug and Play, "while traditional access methods, each wire need to go through complicated debugging before access to equipment. At the same time, the substation optical cable design has also been optimized. 19 prefabricated optical cables, a total length of about 1378 meters, 83 prefabricated cables, a total length of about 2159 meters, compared to conventional substation cable saving about 4 km.

Constant Cang substation project site equipment control cabinets are used intelligent terminal cabinet, to achieve the electrical equipment online monitoring and intelligent control. The whole station realizes the optical fiberization, the main control room adopts the integrated information platform, realizes the information sharing of the whole station and real-time linkage of the data.

In addition, through the adoption of "standardized design, factory-made processing and assembly-oriented construction", the construction period of the project is only 88 days, which saves 210 days in comparison with the normal construction period and saves two-thirds of the construction period the above.

EVA Foam Printer

EVA Foam printer are widely used to print a lot of materials including acrylic, metal, wood, glass, plastic, phone covers, MDF, melamine board, foam boards, PVC boards, ceramic tiles, etc. Mirror effect, 3d effect, embossing effect and flat effect can be easily achieved.

With Fast & easy is a big advantage for digital uv printing. And another advantage makes digital uv printing popular in many fields is the printing durability.

UV Printer is a new technology, you can print custom designs which can increase added value of your crystal with competitive ability. And the colorful designs on the crystals are high fastness, excellent adhesion and waterproof. Thanks to Digital LED UV Flatbed Printers, promotional gifts such as awards, trophies, plaques, medal have personality with good reducibility and high quality.
