CapSwitcher® 38 kV - 170 kV Catalog Flyer

Product catalog summary

Overview: The CapSwitcher® is a high voltage capacitor switching device designed for reliable, long-life performance in improving power factor through capacitor banks. It is specifically engineered to provide restrike-free switching using SF6 gas and closing resistors to mitigate voltage transients and current inrush.

Features:

Closing resistors minimize voltage and current transients.
Design virtually eliminates restrikes.
Simple, cost-effective mechanical design ensures repeatability.
Long operational life of 10,000 operations.
Eliminates the need for inrush reactors.
Can be used as a protective device due to its interrupting rating.

Specifications:

Maximum Voltage Ratings: 38 kV – 170 kV.
Capacitive Current Switch Rating: 600 A (38 kV to 72.5 kV), 650 A (123 kV to 170 kV).
Primary Interrupting Ratings: 25 kA RMS Sym (38 kV to 72.5 kV), 40 kA RMS Sym (123 kV to 170 kV).
Short Time Withstand Ratings: 40 kA RMS Sym (1 sec) for lower voltages, 63 kA RMS Sym (18 cycles) for higher voltages.

Application: Suitable for single bank or back-to-back, grounded or ungrounded configurations. It makes and breaks circuits in SF6 and is designed for restrike-free performance. Multiple resistor sizes allow for performance optimization.

Rated Duty Cycle: CO – 5 min – CO – 5 min – CO, with a spring charge time of 15 seconds.

Key Advantages: The device offers a straightforward mechanical design for long life and repeatable operation, with a common gas system providing local and remote status indication.

Ratings:

Maximum Voltage Rating (kV): 38 to 170.
BIL (kV): 200 to 750.
Continuous Current: 600 A to 650 A.
Primary Fault Interrupting Rating: 25 kA RMS (standard and optional -50°C), 40 kA RMS (standard).
Short-Time Symmetrical Withstand: 40 kA RMS/Sec to 63 kA RMS (18 cycles).
Endurance Life: 10,000 operations.
Ambient Temperature Rating: -40°C to +50°C (standard), -50°C to +50°C (optional).

Capacitor Switching Ratings (IEEE C37.09a-2005): The device supports various closing resistor values and high-frequency transient making currents, tailored to different voltage ratings.
