Conditions of use
• Ambient air temperature: maximum temperature +40°C, minimum temperature -15°C;
• Altitude: ≤2000m;
• Ambient relative humidity: daily average ≤95%, monthly average ≤90%;
• Air: not suitable for places with corrosion, severe pollution, flammable gases and severe vibration;
• If an earthquake occurs, the earthquake intensity cannot exceed 8 degrees.Main technical parameters
Project Unit Parameter Rated voltage kV 40.5 Rated insulation level Lightning impulse voltage (full wave) kV 185 Power frequency withstand voltage (1min) 95 Rated frequency Hz 50 Rated current A 630、1250、1600、2000 Rated circuit breaking time Power frequency withstand voltage (1min) kV 20、25、31.5 Rated short-circuit making current (peak value) kA 50、63、80 Rated dynamic stability current (peak value) kA 50、63、80 4s thermal stability current (effective value) kA 20、25、31.5 Enclosure protection level Vacuum circuit breaker cabinet mm IP4X Dimensions (width x depth x height) SF6 short circuit breaker cabinet mm 1400×2200×2600 Structural features
The switch cabinet structure is designed according to the armored metal-enclosed switchgear standards in GB3906-2006 and IEC298. The whole is composed of two parts: the cabinet and the withdrawable part (trolley). The cabinet structure is assembled, bolted and combined, and the metal partition is used to divide the inside of the switch cabinet into the circuit breaker room, main busbar room, cable room and relay instrument room. The shell protection level reaches IP3X, the protection level between each compartment is IP2X, and all metal structural parts are reliably grounded. There is an independent exhaust pressure release channel between the compartments of the main circuit system.
According to the purpose, the trolley can be divided into circuit breaker trolley, voltage transformer trolley, metering trolley, isolation trolley, etc. The appearance dimensions of various trolleys are the same, and the trolleys for the same purpose have good interchangeability; the trolley has a test 1 isolation position and a working position in the cabinet, and each position is equipped with an interlocking device to ensure that the trolley cannot be moved at will when it is in the above two positions.Circuit breaker technical parameters
