800KV SUBSTATION LAYOUT
ELK-4 SERIES FOR 800KV
High-voltage circuit breaker At core of our switchgear system is classical puffer
CB with three chamber and an optimized and solid layout that optimal adapt with the pre-in-section closing resistor stack.
The KEMA- certified CB is designed to provide optimal performance and low maintenance.
HOW DOES IT WORK ?
High-voltage circuit breaker
Disconnector or earthing switches
• Disconnector provide a safe insulating gap to isolator with different potential.
• The angular Disconnector integrated in the busbar ensures the highest degree of flexibility in lay outing.
Disconnector or earthing switches
• Earthing switches connect isolating section of the switchgear to the ground to protect personal during maintenance and assembly work.
Voltage Transformer • The single pole inductive voltage transformer are
connected to the switchgear with a standardized connecting flange and a partition insulator.
• The primary winding is coiled on top of core and the secondary windings. The latter are connected to the terminal in the external terminal box through a gas-tight multiple bushing.
Current Transformer• The core concentrically enclose the primary
conductor and are located outside the gas compartment elimination the need for as-tight feed to the secondary terminals.
