SRM6-12 FULLY INSULATED INFLATABLE RING NETWORK SWITCHGEAR
OVERVIEW
The SRM6-12 fuly insulated inflatable ring network switchgear product is widely ud in 10k/6kV distnibution systems and is the prefered switch productfor various urban and rural user transformation and distribution systemsThe switchgear adopts a modular unit mode, which can be combined according to diferent purposes, t consists of two main categories: fixed unitcombination and expandable unit, meeting the flexible use of compact switchgear in various substations.The SRM6-12 fuly insulated inflatable ring network switchgear is a fuy sealed system, with its charged components and switches enclosed in a stainlesste! body. The entire switching device is not affected by external environmental conditions, thus ensuring operatinal reliabiity and personal safety. Andmaintenance free has been achieved. By selecting expandable busbars, any combination can be achieved, achieving full modularity.The expansion ofbusbar safety insulation and shielding ensures reliabily and safety. The SRM6-12 fuly insulated inatable ring network switchear can provide TV-basedautomation solutions, forming the concept of intelligent switches and minimizing on-site instalation and debugging workdoad.The SRM6-12 fuly insulated inflatable ring network switchgear is divided into non expandable standard configurations and expandable standardconfigurations. Due to the combination of full module and half module, as well as self scalability, it has extremely special flexiblility.SRM6-12 fully insulated inlatable ring network switchgear complies with GB standards. The design life for operation under indoor conditions (20*c )exceeds 30 years.
MODEL AND MEANING
Example:
1.SRM6-12-C/630DL represents the load switch cabinet, ith a rated votage of 12kVand a rated curent of 630.tis extended on the rightside and has a leht cable anty and exit mode.
2.SRM6-12-0F/630lR represents a combination ofload switch unit and fuse combination unit,with a bus voltage of 12kVand a bus curent of 630A The lef side is extended, and the right cable inlet and outlet mode is used.
MAIN FEATURES OF THE PRODUCT
Technical Description
The SRM6-12 fuly insulated inlatable ring network switchgear is installed on a galvanized sheet frame, with the switch unit inside an SF6 gas box made oforrosion-resistant and non-magnetic 3mm thick stainless steel plate.The SF6 gas box is a 'sealed pressure system" that can operate for 30 years under normal operating conditions. The presure of SF6 gas duning normaloperation is 0.15-0.4 bar, The gas box is equipped with a pressure relief device to ensure that the gas can be released from the bottom or rear when thepressure is too high.
Switch unit
the load switch adopts a coaxial rotating double breakpoint method, which operates with kinetic energy through the same operating hole and the slidingblate. Therefore,the switch can only be in one of the three states of "closing, opening, and grounding" at any time, completely avoiding misoperation.
Operating mechanismthe operating mechanism of the switch is instaled at the front ofthe air box, which is treated with special technology to prevent rust and facitate manualperation and maintenance, lt is also easy to achieve electric operation.
