Product Description
Product Description1.Product descriptionGas insulated ring main unit is for the secondary distribution network 11/17.5/24/36 kV. It is a completely sealed system with a stainless steel tank containing all live parts and switching functions. A sealed steel tank with constant atmospheric conditions ensures a high level of reliability as well as personnel safety and a virtually maintenance-free system.
It offers a choice of either switch-fuse combination or circuit-breaker with relay for protection of the transformer. SafeRing can be supplied with an integrated remote control and monitoring unit.2.Service environment:a) Air temperature:Maximum temperature: +40ºC; Minimum temperature:-25ºCb) Humidity:Monthly average humidity 95%; Daily average humidity 90% .c) Altitude above sea level:Maximum installation altitude: 2500md) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.e) No frequent violent shakef)SF6 pressure:1.4barg) Gas leakage year rate:0.2‰/yearh)Ip range:IP67i)Thickness of gas stainless steel tank is 3.00mmj)Bus is 400mm2 Cu,Bus earthing is150mm2Cu3. Modularization designThe modular design scheme is adopted. The basic modules are load switch module, combined electrical module and other special function modules.Any combination of these modules forms a common box structure, in which any one function is roughly the same as the internal structure of the basic module4.Standards
IEC 62271-100 high voltage alternating current circuit breakersIEC 62271-105: alternating current switch-fuse CombinationIEC 62271-102: alternating current disconnectors and earthing switchesIEC 62271-200 A.C. metal enclosed switchgear and controlgear for rated voltage above 1 kV and up to and including 52 kVIEC 62271-103 high voltage switches for rated voltage above 1 kV and less than 52 kVIEC 60694: Common specifications for high-voltage switchgear and controlgear standards5. Flexible exit and extension modeAll modules can realize the connection mode of side outgoing line and side expanding line or outgoing line and top expanding line according to the customer's requirements, so as to meet the demand of power supply scheme to the greatest extentProduct Parameters
