The JLGYZ8-12 series high-voltage vacuum prepayment metering

device is designed for use in three-phase power systems with AC

frequency of 50Hz and voltage of 12kV. It serves the purpose of

breaking and closing load currents, providing overload and shortcircuit protection, quick-break protection, timed delay protection,

and automatic reclosing function. Additionally, it can be equipped

with surge arresters or isolating switches (referred to as \"combined

intelligent circuit breakers\") according to user requirements. The

intelligent circuit breaker has its own power supply, allowing remote

control, and comes with CT and PT interfaces to meet telemetry

requirements.

Altitude: ≤1000m (If increased altitude is required, the rated level should be adjusted accordingly).

Ambient Air Temperature: Upper limit +40°C, Lower limit -40°C.

Seismic Intensity: ≤8 degrees.

Average Relative Humidity: Daily average ≤95%, Monthly average ≤90%.

No exposure to fire, explosion hazards, severe pollution, chemical corrosion, or intense vibration.

The JLSZK-12W2 type three-phase outdoor silicone rubber cast

combination transformer (commonly known as the power metering

box) is composed of two outdoor silicone rubber cast current

transformers and two outdoor silicone rubber cast voltage

transformers. Both current and voltage transformers use imported

outdoor cycloaliphatic silicone rubber casting. This product has high

accuracy, low temperature rise, fire resistance, explosion-proof,

anti-theft, pollution resistance, good dynamic thermal stability, and

no risk of oil leakage. It is mainly used for energy metering in threephase AC circuits with a rated frequency of 50Hz and a rated voltage

of 10kV.
