KYN28A-24 is a relatively common high-voltage switchgear at present, rated voltage is 24kV. The equipped vacuum circuit breaker is in the middle of the switch cabinet, that is, the circuit breaker is located in the middle of the front cabinet of the switchgear, so the lower space can be saved for the expansion of other schemes or used as a cable room.

Application Channels:

Mainly used in power plants, substations, transformation and distribution centers of industrial and mining enterprises, and large-scale high-voltage motor starting equipment, etc., for receiving and distributing electric energy, and for controlling, protecting and monitoring circuits.

KYN28A-24 Structural Features

1. Cabinet structure

Fully enclosed metal armored design, divided into four independent compartments: circuit breaker room, busbar room, cable room, relay instrument room, each compartment has a metal partition, high safety.

The circuit breaker adopts a central trolley structure, which can be easily pulled out for maintenance or replacement, reducing power outage time.

2. Core components

Vacuum circuit breaker: strong arc extinguishing ability, long life, environmental protection and pollution-free.

Microcomputer protection device: intelligent monitoring and protection functions, support remote operation and communication.

Five-protection interlocking mechanism: ensure safe operation and prevent misoperation.
