Summary of KYN28-24 switchgear
KYN28-24 indoor metal-clad enclosed switchgear is applied to 3-phase AC 50Hz/24kV single bus bar and single bus bar section electric power system, with the function of “five preventions”. It has perfect and reliable prevention function against misoperation. The removing compartment of the switchgear may be assembled with vacuum circuit breaker, vacuum contactor, load breaker switch and VT handcart etc. The switchgear complies with the standards of IEC 60298, GB3906, and DL404. electrical distribution panel
Structural feature of KYN28-24 switchgear
The enclosure is made of aluminum-zinc plated steel by CNC machine with high precise dimension, short production cycle, excellent mechanical strength and nice appearance.
The switchgear is composed by the enclosure and drawable CB. The panel and main components are shown in figures. The incoming panel and outgoing panel are the basic schemes of switchgear panel. There are other derivative schemes, such as: contact panel or metering panel. In addition, there are so many schemes of the switchgear panel with load switch, VCB (Vacuum Circuit Breaker) truck, VC (Vacuum Contactor) truck, disconnect truck. The bus-bar compartment, CB truck compartment, cable compartment and relay compartment are separated by metal sheet. The switchgear has flexible operation for CB truck’s movement and clear position instruction. The earth switch allows making short circuit current and gains creditable mechanical interlock. The protection degree of enclosure is IP4X; the protection degree is IP2X when the door of VCB room is open and the truck is drawn out.
The panel has two modes of configuration: single-face configuration and face-to-face configuration.
The details of structure and main components are referenced in order documents.
