• Economy.

Environmental Qualification:

Ang mga kagamitan ng switchgear ay in-evaluate sa pamamagitan ng optimum analysis at test para sa madaling pag-maintain at matagal na lifetime. Hermetically sealed primary enclosure para sa proteksyon laban sa environmental conditions (dirt, moisture, vermins, insects, at mataas na altitude).

Technical parameters:

RGIS-G20 Switchgear:

Ang serye ng RGIS-G20 gas insulated metal-clad switchgear ay ginagamit sa single bus system lamang, voltage class hanggang 40.5kV. Voltage transformer at surge arrester na ginagamit para sa main bus maaaring maayos sa isang panel, madali itong i-maintain.

RGIS-G80 Switchgear:

Ang serye ng RGIS-G80 gas insulated metal-clad switchgear ay applicable sa single o double bus system at maaaring mag-combine ng iba't ibang schemes. Ang application ng plug-in technology na nagpapahintulot sa voltage transformer at surge arrester na ma-arrange sa incoming panel o surge arrester na naka-arrange sa feeder panel. Ito ay makakatipid sa space.

RGIS-G90 Switchgear:

Ano ang mga technical parameters ng 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.
