Pagsusi sa Environment:
Ang mga switchgear equipments gi-evaluate pinaagi sa optimum analysis ug test aron mas sayon ang maintenance ug long lifetime. Hermetically sealed primary enclosure alang sa proteksyon labi sa environmental conditions (dirt, moisture, vermins, insects ug high altitudes).
Technical parameters:
RGIS-G20 Switchgear:
Ang RGIS-G20 series gas insulated metal-clad switchgear gisultiha sa single bus system lang, voltage class hanggang 40.5kV. Voltage transformer ug surge arrester gamiton sa main bus mahimong maayo nga i-arrange sa usa ka panel, mas sayon sa maintenance.
RGIS-G80 Switchgear:
Ang RGIS-G80 series gas insulated metal-clad switchgear applicable sa single o double bus system mahimo magbutang sa combination sa iba't ibang schemes. Ang paggamit sa plug-in technology nga naka-arrange ang voltage transformer ug surge arrester sa incoming panel o surge arrester sa feeder panel. Kini makapadami sa espasyo.
RGIS-G90 Switchgear:
Ano ang technical parameters sa SF6 gas-insulated metal armored switchgear?
Rated Voltage:
Common rated voltage levels include 12kV, 24kV, and 40.5kV, and can be selected based on the voltage level of the power system and application requirements.
Rated Current:
The range of rated current values is broad, typically from a few hundred amperes to several thousand amperes, such as 630A, 1250A, 1600A, 2000A, 3150A, etc. The specific value depends on the size of the connected load and the capacity requirements of the power system.
Rated Short-Circuit Breaking Capacity:
Typically ranges from 20kA to 50kA. This parameter reflects the switchgear's ability to interrupt short-circuit currents. The rated short-circuit breaking capacity must be greater than the maximum possible short-circuit current in the power system to ensure reliable interruption of fault currents during a fault, preventing the accident from escalating.
Gas Pressure:
The rated pressure for SF6 gas is generally between 0.03MPa and 0.16MPa. The actual operating pressure may be adjusted according to the specific requirements of the equipment and environmental factors such as temperature. During operation, it is necessary to monitor and control the gas pressure to ensure it remains within the specified range, thereby ensuring the insulation and arc-quenching performance of the equipment.
