Metal-Clad Compartmentalized Construction
The KYN61-40.5 is divided into four defined areas: instrument room, handcart room, busbar room and cable room.
Instrument room: Accommodates the secondary equipment arrangement shown in the switchgear structure.
Handcart room: Houses the withdrawable circuit breaker handcart.
Busbar room: Contains the main busbar and busbar bushing.
Cable room: Accommodates the cable connection, current transformer and earthing switch.
Withdrawable Circuit Breaker Arrangement
The KYN61-40.5 uses a withdrawable circuit breaker handcart installed in a dedicated handcart compartment.
Circuit Breaker: Withdrawable circuit breaker handcart
Breaker Compartment: Dedicated handcart room
Primary Connection: Contact box
Secondary Connection: Secondary plug
Circuit Breaker Compatibility: VS1 / VD4 series
Project Configuration
The final KYN61-40.5 lineup is based on the customer's single-line diagram, feeder arrangement and protection requirements.
Control Circuit Voltage: DC 110 / 220 V; AC 110 / 220 V
Single-Line Diagram: Incoming, outgoing, transformer feeder and bus-coupler arrangement
Feeder Schedule: Panel quantity and feeder arrangement
Transformer Feeder Requirements: Transformer feeder electrical requirements
CT / VT Requirements: Current and voltage transformer requirements for measurement and protection
Protection Requirements: Required protection functions and relay configuration
Cable Arrangement: Cable connection and entry requirements
The approved single-line diagram and feeder schedule are used to confirm the final lineup before production.
Applications
Substation Distribution
Incoming and outgoing feeder panels for indoor 40.5 kV substations.
Transformer Feeders
