KYT8 ( KYN28A ) - 24 Safety Electrical Metal Clad Switchgear Metering Cabinet
Overview
KYN28-24 type armored remove AC metal- switch cabinet is three -phase AC50Hz,rated voltage 24KV indoor power distribution equipment .As power plants ,substations ,industrial &mining enterprises to accept amd distribute of electric energy to control ,protect and monitor, circuit , ect. Can also be used to control the place of frequent operation .
1. Service condition
2. Structure
2.1 Enclosure
Switchgear enclosure adopts imported aluminum zinc steel sheet by
CNC machine tool processing, and use multi-fold workmanship strong
oxidation resistance and corrosion resistance, light weight, strong
mechanism strength.
Enclosure with degree of protection IP4X is divided into four
separated comp artments, when the door opens the compartment and
circuit breakers the degree of protection is IP2X
2.2 Trolley(VCB)
The trolley frame assembled with thin steer after CNC machine tool.
The trolley co-ordinated with the switchgear as to make the
mechanical interlock safe and reliable. Trolley with the same
specification are interchangeable.
Circuit breaker trolley is equipped with vacuum circuit breaker and
other auxiliary equipment, the VCB can be circuit VD4 of ABB or
VT19 manufactured by ourselves. It can be reliably locked in
disconnected position, test position to ensure reliable interlock.
2.3 Busbar component
The branch bus is connected to the static contact box and main
busbar without other supports. Main busbar is separated and fixed
by the bushing in case of arc failure.
This construction can effectively prevent the accident spreading to
other cabinets.
2.4 Instrument cabinet
All kinds of switch, status-indicator and measuring instrument etc
could be mounted on the door of the instrument. Protective relay,
secondary wire, terminal and air switch, low-voltage fuses, etc,
are equipped inside the instrument cabinet.
2.5 Fail- safe interlock
There is a "anti-5" mechanical latch between the disconnector, VCB
and panel door, a reliable measurement to prevent from
mis-operation, convenient and safe maintenance, flexible operation.
