►Product overview
In recent years, with the general improvement of design quality, environmental protection performance and manufacturing technology of solid insulated ring main units, the product quality and standardization degree have met the requirements of users. Through the promulgation of DL standard and the gradual expansion of usage, solid insulated ring main units will become the mainstream products in smart grid construction.
CKSS solid insulated ring main unit is an intelligent, environment-friendly and all-working equipment with high reliable operation safety, which is suitable for 12kV secondary distribution system. It has the characteristics of complete insulation, long service life, maintenance-free, small occupied space, safety and reliability, and is not affected by the environment. Widely used in industrial and civil Ring Main Unit and terminal power supply, especially in small secondary distribution stations, switching stations, industrial and mining enterprises, airports, railways, commercial areas, high-rise buildings, highways, subways, tunnels and other fields, especially in plateau, humid, cold and low-lying special environments, the products are not only widely used in China, but also exported to western Europe, northern Europe and other countries.
►Technical parameter
►Product features
Excellent performance: the product has been analyzed, calculated and optimized by electric field simulation.
Flexible scheme: there are breaker type, direct-acting type, upper isolated upper grounding structure and lower isolated lower grounding structure, which meet the technical requirements of national grid standardization design and southern grid.
Modular design: it is divided into four modules: switch body, cabinet body, low-voltage box and bus bar. The cabinet body can be designed into complete sets of products with various styles according to customer requirements; Compact structure; Small size, light weight, easy to carry and replace. Unit structure, overhead bus mode, convenient installation, and can realize arbitrary expansion and replacement of units.
Strong environmental adaptability: suitable for areas at an altitude of 5000 meters, cold, low-lying and humid, coastal high salt fog, strong sandstorm and so on.
High degree of intelligence: meet the requirements of smart grid and intelligent operation and maintenance of State Grid and South Grid.
Safe and reliable: the switch adopts three-phase independent split structure, the protection level of the main circuit is IP67, and the overall maintenance-free design; The pole adopts surface arc zinc melting process to realize continuous and reliable grounding of the surface of the insulator; The switch is equipped with LED lights to isolate the fracture, and the three-phase fracture is clearly visible, which improves the safety of product maintenance.
