Original product description
Application: The 145kV SF6 Circuit Breaker is designed for use in power systems with a frequency of 50. Hz and a nominal voltage of 145kV. It serves as a primary power equipment for control and protection in power plants, substations, and industrial and mining enterprises.
This breaker is suitable for environments requiring operation under rated current or repeated on/off short circuit current, and can directly replace various oil circuit breakers with transition brackets. Usual Service Conditions: Frequency: 50.
Hz Rated Voltage: 145kV Ambient Temperature: -30°C to +40°C Relative Humidity: ≤95% or ≤90% Daily Average Saturated Vapor Pressure: ≤2.2KPa Monthly Average Value: ≤1.8KPa Altitude: ≤3000m Seismic Intensity: ≤8 Air Pollution Level: Level Wind Pressure: ≤700pa Advantages: Compliance with GB1984 standard, GB/T idt OHSAS18001:2007, GB/T idt ISO14001:200.
Superior fracture performance, short arcing time, and extended service life. Mechanical life exceeding 3000 operations. Frequent operation capability, with each set capable of installing 12 current transformers.
Equipped with the new sf6mkz pointer type densitometer, ensuring pressure gauge readings are unaffected by temperature changes. Additional Features: Stable breaking performance, reliably interrupting faults such as short circuits, out-of-step, and near-end line issues.
Simplified arc extinguisher structure for easy maintenance and reliable operation. Long electrical life, with the ability to break 20 times at full capacity and maintenance-free operation for 10 years under normal conditions. Low operating force, utilizing a simple and reliable compact spring operating mechanism.
