1. Technical characteristics of DFW10-12 SF6 sulfur hexafluoride load switch cable branch box
DFW10-12 SF6 sulfur hexafluoride load switch cable branch box is a kind of high-performance equipment widely used in medium-voltage power distribution system, mainly used for cable branching, load switching and power distribution. Its core feature is the use of SF6 gas as insulation and arc extinguishing medium, which has excellent electrical performance and reliability.
Advantages of SF6 gas
SF6 gas has extremely high insulation strength and arc extinguishing ability, its insulation strength is 2-3 times that of air, and it can effectively isolate the current under high-voltage environment. At the same time, SF6 gas will rapidly decompose and reorganize under the action of electric arc, absorbing a large amount of arc energy, thus realizing rapid arc extinguishing and ensuring the safe operation of equipment.
Compact design
DFW10-12 adopts modular design with compact structure and small footprint, especially suitable for places with limited space, such as urban distribution networks and underground cable tunnels.
Three-position load switch
The equipment is equipped with a three-position load switch (closing, breaking and grounding), which provides flexible operation and high safety. The switch contacts are sealed inside the SF6 gas chamber, avoiding the influence of the external environment and prolonging the service life of the equipment.
Intelligent monitoring
Huadian has integrated an intelligent monitoring system in DFW10-12, which can monitor parameters such as SF6 gas pressure, switch status and cable temperature in real time, and transmit the data to the backend management system through wireless communication technology to realize remote monitoring and fault warning.
2.the innovative advantages of Huadian
As a leading enterprise in the domestic power equipment industry, Huadian has shown strong technical strength and innovation ability in the R&D and production of DFW10-12.
High Reliability Design
Huadian's DFW10-12 products adopt fully sealed structure with extremely low SF6 gas leakage rate, the annual leakage rate is less than 0.1%, which ensures the long-term stable operation of the equipment. Meanwhile, the switch contacts are made of silver alloy material with excellent conductivity and wear resistance, which extends the service life of the equipment.
Environmental Protection and Energy Saving
Huadian actively responds to the national environmental protection policy and adopts low global warming potential (GWP) SF6 gas substitution program to reduce the impact on the environment. At the same time, the product design focuses on energy saving and reduces energy loss during operation.
Intelligent Technology
Huadian takes the lead in introducing intelligent monitoring system in DFW10-12 products, which realizes remote monitoring and fault diagnosis of the equipment, improves operation and maintenance efficiency and reduces labor costs.
