Single bus connection

Single bus connection

Operation sequence of circuit breaker and isolating switch:

Power supply operation sequence: first close the disconnect switches on both sides of the circuit breaker, and then switch on the circuit breaker.

Operation sequence of power failure maintenance: first open the circuit breaker, and then disconnect the disconnect switches on both sides of the circuit breaker. After the line partner is powered on, close the grounding switch.

busbar trunking

Single bus connection

Features: simple, clear and less equipment.

When the busbar is faulty or overhauled or the busbar disconnector is overhauled, the entire coefficient is blacked out.

The power supply to this circuit must also be stopped during the maintenance of the circuit breaker.

panel bending machine

Scope of application

Single-source power plants and substations, and the number of outlet circuits is small, and users have low requirements for power supply reliability.

Single bus section wiring

Features: Reduce the power failure range during bus fault or maintenance.

The power supply of this circuit must be stopped during the maintenance of the circuit breaker.

how to make bending machine

The number of bus sections is usually 2 to 3 sections. Too many sections add section breakers.

Scope of application

6~10kV power distribution devices with 6 or more outlets;

The number of 35kV outlets is 4~8 times;

The number of outgoing lines of 110~220kV is 3~4 times.
