GXGT1-12 solid insulated switchgear is a new generation of fully insulated and fully enclosed environmental protection switchgear. All live parts are sealed in epoxy resin insulated cylinder and silicone rubber enclosed bus with ground shielding layer sprayed on the outer surface. Adjacent cabinets are connected by plug-in solid insulated bus. The whole switchgear is not affected by the external environment.
GXGT1-12 solid insulated switchgear has three basic functional unit cabinets: vacuum load switch cabinet, vacuum load switch fuse combination electrical cabinet and vacuum circuit breaker cabinet. It is suitable for 10kV three-phase AC 50 Hz single bus system as the equipment for receiving and distributing electric energy. It has the functions of control, protection, monitoring and communication for lines, and can be used in airports, subways and large cities It is especially suitable for small site, harsh environment, high altitude, maintenance free and other occasions.
1. Safe and reliable - all live parts are sealed in the epoxy resin insulated cylinder and silicone rubber enclosed bus with ground shielding layer sprayed on the outer surface to realize full insulation, full sealing and maintenance free. It is not affected by environment and high altitude. The compartment design avoids the possibility of phase to phase discharge.
2. Simple and compact - one of the smallest products of the same kind of ring main unit, the size of load switch cabinet and circuit breaker cabinet is 400 × 750 × 1500, and the size of load switch + fuse combination electrical cabinet is 440 × 750 × 1500.
3. Green environmental protection - no greenhouse gases such as SF6.
4. Intellectualization - the circuit breaker mechanism has reclosing function, the load switch mechanism has tripping function, and can be equipped with intelligent control unit components to adapt to the realization of distribution network automation in power enterprises.
5. Visible fracture - the three positions of conduction, isolation and grounding of three position disconnector are visible.
6. Flexible expansion - various scheme combinations and scheme expansion can be carried out through plug-in insulated bus, and the expansion bus is set on the top of the cabinet, which conforms to the user's habits and is easy to install.
7. A lower grounding device is set at the outlet side of the fuse at the lower end of the load switch + fuse combination electrical appliance function cabinet to ensure personal safety when replacing the fuse.
8. The epoxy resin insulated cylinder is provided with explosion-proof pressure relief hole.
9. It has perfect mechanical and electrical interlocking function to meet the requirements of "five prevention".
