zcsf-12 indoor high-voltage ac sulfur hexafluoride intelligent ring network switchgear (10kv sf6 ring network cabinet)
zcsf-12 indoor high voltage ac sulfur hexafluoride smart ring network switchgear
zcsf-12(f•r) fully enclosed sf6 smart ring network switchgear for indoor use, is a three-phase ac 50hz high voltage switchgear set, as a 10kv system to receive and distribute electric energy and to achieve circuit control and protection, is a new generation of miniaturized sf6 fully insulated ring network switchgear. with excellent electrical performance, easy installation, reliable operation, flexible combination, maintenance-free, better performance and price ratio, etc., widely used in industrial and civil cable ring network and power supply end, especially suitable for small secondary distribution power station, open and close, industrial and mining enterprises, urban residential areas, railways, high-rise buildings and other power systems as the acceptance and distribution of electric energy.
◇ switch cabinet structure, performance and characteristics. ◇
the sf6 air box is made of stainless steel plate welded, and the protection grade reaches ip67. the air box has an on-site air filling valve. primary components such as load switch, ground switch, fuse support and bus bar are sealed in sf6 gas box; the high voltage fuse is installed in the sealed insulated cylinder, and the insulation is completely free from the influence of external environmental conditions such as condensation and pollution. with full sealing, full insulation performance, has strong flood control capacity, maintenance free, can operate safely under harsh environmental conditions. the main busbar in the cabinet is fixed on the upper part of the box by the busbar insulator, which can be easily expanded through the busbar connector. modular design, small volume, inlet and outlet wire ring network cabinet size uniform. the modular structure of unit type and common box type can be extended and combined arbitrarily according to user requirements. flexible operation, reliable interlocking, meet the "five prevention" function requirements, the base is made of aluminum zinc plate assembly, high mechanical strength, excellent anti-corrosion performance. can also be installed in the outdoor protective box for use. users who can adapt to the requirements of distribution automation.
