GENERAL INSTRUCTION
GBC-40.5(S)High Voltage Switchgear and 40.5KV Switchgear
For three-phase AC 50Hz, internal voltage 40.5kV indoor power system, as power plants, substations and industrial and mining enterprises distribution chamber for receiving and distributing electric energy. Dual-bus structure and derived products.
Used equipment structure, the air insulation based. Cabinet angles and welded from sheet metal bending, the cabinet has separate meter room, handcart, isolating contacts room and cable room. Switchgear has a perfect and reliable blocking device.
SERVICE ENVIRONMENT
a. The Ambient temperature upper limit and lower limit are respectively +40°C and -40°C; (allowing storage and transportation at -30°C);
b. Altitude is not more than 1000m;
c. Relative humidity: daily average value should not be more than 95%, while monthly average value should not be more than 90% (+25°C);
d. Seismic intensity should be not more than 8°;
e. Places without fire, explosion risk, serious pollution, chemical corrosion and violent vibration.
DESIGN AND STRUCTURE
The switch cabinet is metal-clad. Its structure design accords with the standards GB3906-91, IEC298, DL404 and DL402. The crust structure is made of steel plates by means of bending and welding, which are joined by bolts. The hand buggy panel is the door of cabinet. The bosom of switch cabinet is divided into a breaker chamber, a main bus bar chamber, a cable chamber and a relay chamber by metal partitions. The degree of protection of the entire crust and compartments is IP2X equally. All the metal structures are connected to ground reliably. All the compartments of main circuit system have pressure release channels for independent exhaust.
