36kV/38kV Indoor Vacuum Servo Motor Controlled Switching Circuit Breaker

Description：

VD4-CS is the unique solution based on new vacuum interrupter technology and an innovative actuation systems up to 38kV, 1250A, 31.5kA and with superior noise-free performances, to support your business needs in reactive power compensation.Noise-free power quality by safe and reliable switching and protection of capacitor banks.

Key benefits:

• Inrush elimination thanks to high accuracy in controlled switching technology.
• Up to 5-times higher performance than the market standard with 10,000 maintenance-, inrush- and restrike-free operations.
• Enables elimination of inrush limiting reactors and resistances, leading to significant cost and space savings.
• Cost saving by as much as 20%, using same ratings, same interfaces of existing MV substation thanks to optimized footprint equivalent to standard distribution breakers.
• Reduced total cost of capacitor bank operation due to elimination of downtime for breaker overhaul and a lifespan 5 times the market standard, with predictive health indication.
• Fast and reliable support thanks to ABB’s global footprint.
• Assets optimization having both circuit-breaker and capacitive switching devices in one single solution.
• Enables increased lifespan of capacitors by more than 10% in e.g. 3 years.

Key features:

• Embedded advanced diagnostics.
• Up to 38 kV, 1250A, 31.5 kA.
• 10,000 maintenance-free and noise-free operations.

The CB comprises of:

• Three poles in epoxy resin containing the vacuum interrupter.
• Three brushless servomotors, one per phase with double encoder.
• Three electronic controllers, one per phase, communicating hierarchically with each otherand with the first unit controls the entire system.
• An electronic supply unit.
• A capacitor for storing the energy required to operate the CB in the absence of auxiliary supply.
• Three sensors and three mechanical position indicators.
