Prefabricated Fixed AC Metal-clad Switchgear

HXGN15-12F), HXGN15-12(F.R)Prefabricated fixed AC metal-clad switchgear (hereinafter refered to as "switchgear' is used forrated voltage of 12kV, rated current of 630A and below in the ring network power supply or radial power supply system. it isparticularly suitable for installation in prefabricated substations as control and protection equipment for power systems. Theproduct is equipped with the FLN36-12D type SF6 load switch or FLRN36-12D type load switch and fuse combination electricalappliances with insulated enclosure. t features small size, ight weight, easy operation, light operating force, reliable interlockingand maintenance-free characteristics. lt is a new generation of high-voltage switchgear needed for urban power grid renovationand construction.
This product complies with GB3906 ("3~35kV AC Metal-Enclosed Switchgear"”, GB/T1 1022 ("Common Technical Requirements forHigh-Voltage Switchgear and Control Equipment Standards”), 1EC62271-200 (“"AC Metal-Enclosed Switchgear and ControlEquipment with Rated Voltage Above 1kV up to 50kv"》, and DL/T404 ("Technical Conditions for indoor Ac High Voltage SwitchgearOrder Rejection") standards.

Ambient air temperature: -15℃ to +40℃.
Altitude: 2500m and below Humidity conditions: Daily average not exceeding 95%, daily average vapor pressure not exceeding 2.2kPa.
Monthly average not exceeding 90%, monthly average vapor pressure not exceeding 1.8kPa.
Seismic intensity: Not exceeding 8 degrees.
Locations without obvious pollution, such as corrosive or flammable gases.
Note: When exceeding the normal operating conditions mentioned above, users can negotiate with the company.

The switchgear consists of a cabinet, main switch (SF6 load switch or combination electrical appliances), grounding switch, meterl room, busbars, and other electrical and auxiliary components.
The cabinet is assembled from aluminum-zinc steel plates through modularization. A pressure relief channel is provided behind the cabinet to protect operators in case of internal faults.
The busbar room's busbar is covered with insulation and directly connected to the wiring terminals of the load switch. The three-
phase busbars are arranged vertically, allowing the switchgear to be easily expanded on both sides and facilitating layout changes.
The meter room is located at the top of the switchgear and can accommodate ammeters, voltmeters, indicators, and electricl operating mechanisms.
